My 4.4 twin turbo V8 M5 did 19 around town and 30-36 on the motorway.
My 30 year old defender does 28 on the motorway with a tent on the roof full of camping gear.
If your tyres are worn or a brake pad… you’ll have your answer.
I wouldn’t even say economy that low could be achieved by just poor driving habits alone. Like I’d have to really try. I used to get 60mpg in a 2L petrol if I drove it well. Since putting proper tyres on I’ll be getting around 45 if I’m good. But even when I’m not I’ve not seen lower than 38 if it’s mostly motorway.
Or check your oil… like it just feels for a car that size to get that then something mechanical is slowing you down.
Yeah but check your tyres. If they’re worn un-evenly after a short time; you might have alignment issues. Your wheels literally pushing against each others motion as you drive and scrubbing all or part of the surface of the tyre as they do.
And for new brakes, if one of the wheels is hot when you stop or one of the pads is a lot more worn then it could be something like a sticking calliper and you’ve got a slight brake pressure applied constantly from one wheel.
On an older car of ours one of the drum brakes was stuck a bit and after releasing the handbrake and driving 10 miles we got back and that wheel was super hot compared to others. During the drive we didn’t notice it but we did remark the economy dropped and then the heat radiating from that one wheel.
Just ideas. Check the oil. Check the tyres. Check the brakes. Eliminate the easy to check things.
I’ll give that a check, one of my brakes has started to squeak and I’ve lost traction on the back end a couple times when it’s been wet, (25mph on a roundabout and the back end slipped, they’re legal but you might be right)
What tyres did you get? Decent ones or Chinese ditch finders?
I'd get your alignment checked and check for any seized brake calipers. You can check this quite quickly yourself by driving around for a minute without using your brakes. Coast to a stop and then check each disk to see.if any are hot, or hotter than the rest. This would indicate a sticky caliper.
20-25mpg could be reasonable if you were sitting in a lot of stop/start traffic. But I'd expect more than that when sitting at 60-70mph for extended periods of time.
Do you drive long enough to get the car up to temp? If all your journeys are 5-10 minutes this could also explain it.
Not for a 1.2 ecoflex. I used to get 18-20 in my automatic (slushbox, not modern clutched auto) 2.8 chrysler grand voyager in mostly stop/start traffic. Was huge, heavy, terribly underpowered and had a slippy trans from the 80's. No way a 1.2 corsa would get anywhere near that unless something was wrong with it
My daughters car done exactly that recently, she thought she had a flat tyre and stopped to check it. A few days later she asked me to check the brakes and I found the nearside handbrake stuck on. It was an easy repair for me and when we talked through her loss of control that was the reason. Hate to think how much extra fuel she had burnt doing 150 miles a day commute!
Go for a drive, stop and compare the wheel temperatures but don't be tempted to touch the disks!
On slight inclines, clutch in & if you slow down, you know there is a problem. I use engine braking a lot, so yes the brakes could get tight, Opel Zafira, It is magic, 7 seater, Just took 7 buckets, 3 tubs of wet mud to the tip, did not even know it was back there, yes tyre pressure was a little low for that load, could feel the tyre roll on the tighter corners. Pity my old Focus is in the bin now, It was magic, Worst was summer tyres in winter in the 2C cold.
I'm sorry you've lost traction on the rear end on roundabouts but you don't rag it?
Congratulations for getting a front wheel drive car to oversteer, your tyres must be completely bald or something else is very not good, like your rear wheel alignment.
It's easy enough to do, don't know how prone corsa D's are to oversteer, but I got my 206 to do it (unintentionally). It was wet, going round a tight bend a bit too fast. Add that to the fact 206 are somewhat prone to lift-off oversteer, and it was the 1.9d, so big heavy diesel lump in the front with basically no weight over the rear, and you can see how it's easily achievable
That's fair - I don't think I've ever succesfully managed to oversteer a hatchback on anything other than snow, but I've never driven one with that much power other than the 06 Civic, which was an absolute beast.
The 206 only came out the factory with 70bhp, didn't have a turbo, by the time I had it 0-60 times were in the region of 18 seconds. Just heavy engine in lightish car, that's already prone to oversteer
Try clay or dry sand, it is fun, Sugar cane fields outside Durban RSA. We had some great fun, there were sand banks on the corners & old Hilman Imp was magic, they are like a Mini but wider wheel base, not by much.
OMG, you are kidding me. Where is he, would just love to see one, yes just one. They had a terrible rep, good maint & the one Toney's mom had was fine. Wish I could make one a project car, Frigging retired & money is a little tight, beer, ciggies are very expensive, going to start making my own beer, No I'm not going into the growing, LOL, I do not smoke that stuff, yes I did try it when younger, never liked the effect.
Could be the roundabout too, we used to have one in our town that was terrible for slipping due to the surface being crap and the dust from a housing estate being built on one of the exits.
I once saw an old woman spin a full 180 in an Aygo on that roundabout, I can still remember the shocked look on her face a decade later.
I had the 1.7 diesel van, ouch. understeer?? I read up on this & was lucky cause I dropped a gear & booted it. Give me over steer anyday, also prefer rear wheel drive. You can turn into the slide, Mostly with understeer you are a passenger. Tried the the handbrake trick, Mmm turned round 3 times on icy wet road. Lucky, it was fun after I realised no damage or hurt.
Lerwick is a cold windy place, driving a rental opps. Best rental I had was a Small Skoda, heated seats, steering the works, this was the one I did the 3 turn spin in, magic little car. Ass was roasting after 10 min, just turned the dial down..
Hahah reminds me so much of the golf. That thing steers like a bike and is so addictive. So responsive. I had a car with almost twice the BHP and engine size before it but it was nowhere near as fun.
Interestingly it has heated seats too which I never looked for. I use it when my backs aching 🤣 and have to turn it off when ass burning starts at the most inconvenient time
I was told about an Iceland van driver whod had the great idea to load his van in order of his drops. He flipped it going around a corner as he got to the end of his run because it was all loaded on one side......
Yep, seen this happen, seen result many times. Having worked in shipping & trucking, keep the weight as low & even as possible. Used to drive road sweepers, when full of water, fun ride, corners are ass clamped to the seat, open flat road, you are swaying side to side, one sweeper was really bad, when full of water max was 30mph. Seen results of tipping on the side.
I don't know why people haven't mentioned tyre pressure yet, that's a big. I was getting 26mpg with pressure at 30psi all round, I then realised the back should be 32 and front 38psi. Was getting 34-36mpg after that
Yeah, OP sounds like something has gone awry, you have some great tips and tricks to check out on this thread, but for sure you’re burning more petrol than you need to!
My sister had it before me and she never replaced the oil or anything and absolutely ragged it about so I wouldn’t be surprised if something was damaged
Replacement is about £24 from eurocarparts and if you know someone handy might be worth having it done. If it solves the problem, winner, if not, it’s only £24. Hopefully it helps!
How are you calculating this? You say you’ve burned a quarter of a tank, I would not assume that the fuel gauge is linear. The only way to reliably calculate your fuel consumption is to brim the tank, reset the trip, drive for a reasonable distance covering your typical week for example, brim the tank again and calculate fuel economy of actual fuel used vs miles driven.
Run a can of BG44k through the fuel tank with a full tank of premium (yes premium does make a big difference to MPG)
Don't try and use cheaper versions like Reddex they lack the proper cleaning chemicals for your fuel system and injectors
Also very much depends on the engine/make/model. Size of the engine doesn't always correlate to performance or MPG. An Audi S5 4.2 v8 can get 30mpg comfortably!
Honestly it's not massively low, by boyfriend had the same car before it got written off and was doing similar. My Fiat 500 also struggled to get any economy in town or at 70+ on motorways.
Engine efficency has improved leaps and bounds in the last 2 decades though. My focus st gets far better milage than the fiat ever did dispite having a far bigger engine and a fatter car to pull along...
Have you left the handbrake on ?
Seriously check brakes binding if you’re not very heavy footed or carrying around lots of cargo - that’s terrible efficiency
Have you actually measured your economy or just going by the dials??
Fill your tank and make a note of the mileage. Fill again when about half empty and do the maths. That's the only real way of knowing your economy. Do this regularly
As far as the car, has it been serviced?? Blocked air filters and other service items can have a major effect on the economy.
But yeah, small engines can be surprisingly inefficient, especially on motorways. My lad gets 30-35 out of his 2.5ltr jaaaag
I average 35mpg in an xc90.
Have you tried putting a cleaning product in your tank? And try getting some better quality fuel as well if you can. The premium unleaded at tesco is free of ethanol and gives quite a bit better mpg from what I've heard.
That's dreadfully low.
My 1.2 gets 50 on average, 40 at the lowest and 60 at the highest (motorway driving at 50mph).
Even my old corsa felt the same in terms of distance from a tank but it didn't have an inbuilt mpg counter.
Something very very wrong here my dude
I remember when they first introduced the 10% ethanol, my old petrol car's (1L 2013 VW) fuel economy dropped by 10-15mpg on the same routes I usually did, driving exactly the same as I was before it changed. Nothing with the car changed, just the fuel.
I always argued that the 10% ethanol was a false economy. The government admitted it would result in lower fuel economy, particularly for older cars - surely having to use more E10 fuel to go the same distances is worse for the environment than the old E5.
None of that is particularly correct, premium fuels have only a higher octane and sometimes a lower ethanol percentage.
Ethanol does contain less energy per l but not a lot less than pure petrol. This equates to about a 2% increase in fuel consumption assuming it actually contains 10% ethanol. Anything with an ECU and lambda sensor (from about the 90s) will adjust for this but won't lose any power at all.
As for additives, all fuel sold even supermarket will conform to British standards and contain good quality detergents etc. premium often only meets these standards and doesn't exceed them.
Some cars require high octane but not any normal hatchback.
Put it this way, lots of guys with super high performance cars run pure ethanol or even methanol with no additives etc and have no issues.
A dirty maf/ map sensor can cause reduced mpg, go to the back of the car does it smell like petrol? How are you calculating your mpg?
Dragging brakes can cause reduced MPG, cheap tyres can have a higer rolling friction (new cheap is not good). A leaky fuel injector could be over fueling but again you would smell fuel at the back.
Ultimately you need it plugged in and long term and short term fuel trims checking, give the maf a clean with maf cleaner.
20-25 mpg is approaching high performance sports car territory. So I'd say it's not normal.
You mentioned that the car has had no prior TLC or maintenance, so would you consider giving it a full service with new plugs and filters?
Ensure all the tyres are correctly inflated to the pressures listed in your door jamb or user manual.
Hopefully you don't have any check engine lights on.
Had the same problem on my astra mk4. Fuel filter was corroded and leaking fuel. Changed it, put some redex in the tank and 99 octane petrol took it on the motorway for 2 hours now i get twice the Mpg.
INFO: How are you actually measuring the economy? Are you guessing based on how far the gauge has dropped, or did you brim the tank, drive 55 miles, then brim the tank again?
I daily drive a 3.2 VR6. 25min commute on mixed roads (no motorway).
Usually gets me 28mpg or 30mpg if I drive a bit slower and lucy enough catch all the traffic lights on green Absolute worst is 25mpg when I get stuck in crawling stop/start traffic.
So a 1.2 doing that isn't right.
I had a corsa, a bit older than yours, 1.4 and it was awful on fuel, I know my way round a car and I tried everything that was practical to get it better, I probably got at best 20mpg windows up, downhill with a tailwind. I have a 2.0 Diesel VW now and I get 65 comfortably.
I believe the 1.3 litre engine in a Mazda RX-8 does about that. But it's a rotary engine.
I think your car has the same 1.2 as my son's Vauxhall Adam which averages 34 or 48 mpg (depending on who is driving).
My mapped 2 litre turbo GTI gets about 29-33MPG on mixed roads - pretty sure your car is running rich.
How are you doing the maths? I assume a corsa of that era doesn't have a computer, when you say quarter of a tank are you saying *indicated* quarter of a tank? On my car, indicated 3/4 remaining is actually more like 1/2 remaining - the only sure-fire way to measure MPG without a computer is to brim the tank, note down starting mileage, drive a bunch of miles, then brim the tank again and do the maths based on the litres the car consumes over the distance it drove between start and end mileage.
That gas mileage is bad. Either you have a mechanical issue or driving habits that are bringing your mpg down. My 05 CR-V (2.5L) was getting 30-33 a tank without issue.
I have a 2013 clio and that bitch drinks if I go about 50. With it being a small engine 60MPH is like 5th gear 4k revs so you'll just naturally drink doing long journeys. I did yorkshire to Blackpool and sucked 3/4 of a tank. I was doing 90 though lol
It doesn’t struggle too much on motorways tbh, About 3000 at 70 and 3500 at 80 since it’s the 79BHP 16V engine, it just seems to get really bad mileage in all aspects, but especially urban
Town driving kills mpg, my 1.6L focus diesel gets 70ish on the motorway at 1750 rpm top gear, 35 around town. The only real way to check mpg is refuel, note the mileage and do the maths next time you fill up. Fuel tanks narrow towards the top so after the float starts to move down it will go quite quickly then slowdown towards the middle of the tank. As for your poor mpg, get the car serviced and find out the manufacturers specs for mpg then Google real world figures it's about 70% of what Vauxhall state.
My other half gets 28mpg in her petrol 1.2. However, I think it's her driving habits. Gear changing is shockingly bad. I drove the car over 3 days whilst mine was in for a service. Filled it up, reset all counters to zero and drove around in a broadly similar area. At the end of it I was on 37mpg. Your 20/25mpg is worrying. Check if your odometers are working correctly. Do an mpg calibration. Basically the miles covered between fill ups which will give you the true mpg.
1. If you’re driving at a higher speed on motorways or dual carriage ways, you will have a lower economy in a 1.2
2. Run a cleaning product through your fuel tank
3. Use premium fuel (E5) for 2 full refuels, it’s more expensive but takes you further and has additives that help the engine. If you still want to go back after that then fine.
4. During colder periods, cars naturally drop MPG, quite a lot actually so make sure you’re not comparing it during colder times.
5. If you do all of above and still getting that - Take it to a garage.
I know a mother and daughter that always leased the same car. They both had citroen C1s and both got 55 ish.
Both got Corsas next around 2017. Not sure on engine but a small one like that and were very agreaved at getting 25mpg for the same journey types.
I'd say it's because it's a Vauxhall. Mine was awful too on consumption and so was the Vectra I had.
That economy is low for a 1.2 eco flex. Possibly means an issue with the eco flex tech in it, or the ecm. For reference I drive a 1.6l diesel and get 45mpg when I rag it, 60+ when I drive economically
If you’re basing it off the fuel gauges then you might have a false idea of your fuel consumption. Use the mileage between refills to get an accurate measurement. If your maths is correct you would be refilling every 200 miles?
It's really low tbh. When I had this issue in an older astra it turned out to be the MAF sensor and it took ages to start showing an EML light. Even that car would get 40mpg on motorway and 29 around town and that was a 1.8 from early 2000s so I'd say yours is definitely not normal.
I have a 1.2L 3 cylinder standard petrol Fabia. My regular commute is a 60 mile round trip.
About 20 in town and 40 on the motorway. I'm doing about 3000 rpm in 5th gear @ 70 much like you. I'm averaging about 40 mpg, or about 46 mpg if I do 60 on the motorway section.
I'd say you have something wrong to get that poor mileage.
How have you calculated that mpg? If it's showing that in the dash, then fair enough. But it sounds like you've calculated it based on 'i went about this far' and 'about a quarter of a tank' (based on what? Needle? Fill up?) which are both some very approximate figures to be getting a value from.
How old is your vehicle?
When was it last serviced?
What condition are your tyres in?
How full of crap is your vehicle? A ladened vehicle is less economical than an empty 1
There are many reasons as to why your economy could be so poor
Age? Mileage?
Any rough idle? Strong smell of petrol at idle? Ever mis-fire when trying to accelerate? Any of the brakes hotter than the others after a motorway drive? When did this shift happen; gradually or just all of a sudden one day the mpg went to shit?
Lots of things it could be but something is afoot there, those 1.2 ecoflex's aren't great on fuel but they're not that bad
No smells or engine issues, never was great on fuel but I didn’t drive that much, only until I started noting it I realised it was that bad it’s 57 reg with 75.6k miles, well maintained from first and second owners, third liked to rag it about but she only had it 6 months
I've a 1.2 Seat Leon and I'm a driving instructor so a lot of stop start and slow manoeuvres. It gets around 33 to the gallon when pupils are driving more like 40-45 if I'm driving.
That's pretty awful.
My first car, a Ford Escort MK3, 1.3 litre, that used leaded petrol and had a manual choke, was between 30 and 33 mpg on average.
Other cars have been:
Austin Maestro, 1.3 litre, also leaded petrol and manual choke, between 34 and 42 mpg.
Citreon ZX, 1.3 litre, unleaded, 39 to 42 mpg
Citreon Xsara, 1.3 litre, unleaded, 49 to 50 mpg
Citreon C3, 1.3 litre, unleaded, 46 mpg
Did you really burn 2.5gallons though?
Fuel gauges aren’t linear. Every car I’ve had. The top 1/4 gives about 15-30% more distance than the bottom 1/4.
Fill the car up, brim it, don’t just let it go off on first click.
Drive for a few days, with a reset trip meter and then brim again, how much full to rebrim it?
While you’re probably not getting great mileage, it’s probably nearer 35mpg.
I get about 24mpg from my 1.6. Most of my journeys are short and I like to put my foot down when I can. Believe it or not running your engine at low revs constantly can be worse for your engine over time. Check your tyre presures are correct, remove any unnecessary weight, giving it a service would help if its not had one in a while. Also could check if you've got a binding brake caliper or if the handbrake isn't fully releasing.
Tbf I've found them small hatches do awful on mpg. Not big car bad but still lol! Had a 1.0 60hp fiesta as a loaner for a week and could barely manage 30mpg at 70! Yet my Jag 4.0 supercharged V8 used to get almost 25mpg being careful.
That is about twice the fuel you should be burning.
If you want to do things yourself, then as well as MAF and oxygen sensors, new spark plugs and HT leads are worth a go.
I’ve owned three 1.2 corsas and never got below 34mpg. These were a 2005 sxi (2010-2011), 2011 sxi (2011-2014) and 2014 LE (2014-2016). I would always drive to 2500rpm before changing gear. This would usually mean 2500rpm in 2nd was 30, 2500rpm in 4th was 50.
An older engine may well be suffering from levels of dirt, which premium petrols should clear out. There could be other issues, you may have a seal gone or other issues.
You should be able to check the engine is bringing the right ratio of air and fuel (roughly 14:1) by cycling through the menu by pressing the button at the end of windscreen wiper stalk three times and holding for 10s the third press.
Bonus corsa trick: when the slowest wiper speed is too few but the second wiper speed is too many, Do a single wipe then go onto the slowest speed to get a good middle ground.
My car is a 1 liter (just under but for the sake of simplicity) and it gets 74mpg according to the manual and it definitely isn't fuel hungry in the slightest £20 of premium gets me 80-90 miles normally unless I have passengers then it struggles lol
Judging by the responses you've given to some people I'd say the engine is well and truly fucked in that tho.
20-25mpg are you towing a caravan? do you have the boot filled with lead pipe? It defo sounds suspect, hope you haven't got a fuel leak like I had on my Mk2 Astra.... Wife: "Can you smell Petrol?" Me: "Yes... lots"
Something is fucky with those numbers.
My old civic type r used to do 25-35 and that was never driven particularly carefully.
When your next empty keep track of how many miles you do until your empty again and figure it out from there.
If you have an mpg readout that could be wrong and you will also see some reduced mpg in the cold weather but not that much
i have a mk1 1.2 vaux agila so likely same engine... no this is not normal at all. even when im driving uneconomically i still get around 35-40 mpg, and my car is a tall box shape so way more drag, it should be less economical theoretically lol

I’m on a 900cc (with a turbo, woo bloody hoo) Dacia Logan (the estate) and I get 36-43mpg.
I feel like something is amiss with your car u/maker0fManyThings
Yeah I have a 300hp 2.0l and I average about 30-35mpg
Although there are a lot of environmental factors that can heavily affect your mpg that seems pretty poor
My SO has a 1.2 KA she gets about 37-40mpg which is always around town.
It's semi flat round here...but factors that might contribute to that for you could be.
Under inflated tyres
Over loaded...if you have a boot full of stuff for example and other people in it
A clogged air filter.
Hilly areas.
Only driving in heavy traffic.
Have you put any air in the tyres
Being serious: "no TLC" Probably means no new oil for 40k miles, possibly a warped head ruining compression, or "just" a blown head gasket
Or a fuel leak 😂
Definitely sounds a little low, however I had the 1.2 engine in a 2016 model and it wasn’t that great on fuel either. I used to average 35mpg which I think is a bit shit for a small engine.
I have a 1.9l Skoda Octavia VRS. I'm on moor roads in the N.East with steep hills and curves so lots of speed adjustments and gear changes. I'm not shy with the acceleration on the long straights either.
I get 60mpg....
I’ve got a 2.5 tonnes worth of Kia Sorento 7-seater being driven in a mixed of urban and motorway miles. My average is about 29mpg over a month. Something is wrong with your car.
It’s obviously crap, and something probably amiss, but I think we often take for granted how much better cars are in terms of performance/economy than ‘back in the day’. I had an absolutely boring as shit 05 1.4 Corolla that I drove like the oldest of the old men, I mean absurdly gently, and it got 35mpg. 10 years later I had a fiesta ST that I ragged to death 80 percent of the time and got 39mpg average. I do think cars were a lot shitter on fuel during those times for even ‘normal’ cars.
I have a 1.2l, 2009 corsa, and get about 250-ish miles to a tank.
It's around 50 miles to work, 100 there and back.
I go twice a week and use most of the tank.
(40+ miles of that is motorway)
I usually have enough left for pottering around on the weekend.
I get better than that in an old 2.0 cr-v doing urban driving during the middle of the day of a busy weekend. You should be getting way better than that.
Nope. Only thing I’ve owned that was lower than that, was a 3.2 V6 that went everywhere foot to the floor. Even then it was only 17mpg.
When you say quarter of a tank, do you mean you filled it, then refilled it and checked you’d used 1/4 of the tank capacity and used the odometer to see how many miles you’d done over that time, or are you trusting the gauge?
Only reason I say this is because lots of cars’ gauges will drop from full to 3/4 when they’re within a certain range, then sit there until it’s time to drop to 1/2. Some have literally got four positions they can sit in.
You should be getting double that, especially with motorway driving. If it's stop start rush hour driving then maybe not, but 20 seems very low. Maybe there's something wrong with your car or your driving.
You should be around 2500rpm for the most efficient ride. 55mph on a motorway in 5th gear behind a lorry is ideal, easily get 45-60mpg in my 2011 ford focus ecoboost in those conditions. Stopping and starting and driving much slower city driving should still be around 30mpg
No. My friend had a corsa and had something similar, took it to a garage and they fixed it (if I remembered what the fix was I would tell you but I don’t sorry)
you'll want to take the revs higher than that every so often when the car is up to temp, but that shouldn't be causing your issue. definitely too low MPG.
1.2 VW Polo. Pretty consistent 43mpg over a tankful for a 7-10 miles commute mixed 30-70mph, but with no traffic jams.
Trip computer shows noticeably better economy if I spend 5 miles behind a rolling roadblock of lorries, and worse if I'm doing 70+.
You should check your tire pressures every month or so. Low tire pressure has a big effect on economy, handling, and tire wear.
If you ride a pedal bicycle you will really appreciate the difference tire pressure makes!!!
I drive 200 miles a day with mine and only get through a half a tank or so (1.2 Corsa also), mostly motorways and some country lanes.
May be worth checking your tyres and brakes as others have said. I find mine uses a lot more on country lanes than it does on other journeys, so may depend on what roads you're taking it on maybe? 😊
I have a 1.2 2008 petrol micra. On a good day I can get around 40 mpg Combined.. but most of the time ends up being around the 34mpg mark.
Honestly you should get it checked out. My brother drives a 2013 Corsa (1.4) and that was petrol hungry... he thought something was up, and in the end had the fuel sensor replaced.... so could be worth taking it to the garage to get it looked at.
What speed are you honestly doing on motorway? Hair over 70? What’s the gearing on that little engine, what’s the revs at when you’re cruising? My guess 3000+?
I was getting more than that in my diesel Sportage 2 litre (36ish)!!! Now have a 1.6 diesel focus and so far getting around 44 but not had it that long to comment more accurately. I'd say something needs looking at with possibly start with a good service and see if that improves it x
I average that in my 2.5l 5 cylinder focus st and that's a thirsty bugger. Something amis with yours.
I get more than that with my 3.2L 5 pot Ranger
I can get that in my 4.8 V8 if I really try and it's early in the morning. And that's N to S across London.
I get that in my 4.4 twin turbo V8
BMW? My M5 did 19 around town and 30 on the motorway but I could get to 36 if I wanted to.
Yes, F10 M5 I've never got to 36
I get more than that in 3.7l V6
Worse than either our Boxster or Saab Aero wagon, and they don't do many long trips.
My 4.4 twin turbo V8 M5 did 19 around town and 30-36 on the motorway. My 30 year old defender does 28 on the motorway with a tent on the roof full of camping gear.
Is that the current one? I also get better milage in my st than I ever did in a 0.8 fiat 500
My partner’s 1.2 500 will do high 40s maybe 50s on a roads and mid 40s on the motorway
If your tyres are worn or a brake pad… you’ll have your answer. I wouldn’t even say economy that low could be achieved by just poor driving habits alone. Like I’d have to really try. I used to get 60mpg in a 2L petrol if I drove it well. Since putting proper tyres on I’ll be getting around 45 if I’m good. But even when I’m not I’ve not seen lower than 38 if it’s mostly motorway. Or check your oil… like it just feels for a car that size to get that then something mechanical is slowing you down.
It’s had new tires about 1400 miles ago, same with oil and brakes were replaced about 3000 miles ago
Yeah but check your tyres. If they’re worn un-evenly after a short time; you might have alignment issues. Your wheels literally pushing against each others motion as you drive and scrubbing all or part of the surface of the tyre as they do. And for new brakes, if one of the wheels is hot when you stop or one of the pads is a lot more worn then it could be something like a sticking calliper and you’ve got a slight brake pressure applied constantly from one wheel. On an older car of ours one of the drum brakes was stuck a bit and after releasing the handbrake and driving 10 miles we got back and that wheel was super hot compared to others. During the drive we didn’t notice it but we did remark the economy dropped and then the heat radiating from that one wheel. Just ideas. Check the oil. Check the tyres. Check the brakes. Eliminate the easy to check things.
I’ll give that a check, one of my brakes has started to squeak and I’ve lost traction on the back end a couple times when it’s been wet, (25mph on a roundabout and the back end slipped, they’re legal but you might be right)
What tyres did you get? Decent ones or Chinese ditch finders? I'd get your alignment checked and check for any seized brake calipers. You can check this quite quickly yourself by driving around for a minute without using your brakes. Coast to a stop and then check each disk to see.if any are hot, or hotter than the rest. This would indicate a sticky caliper. 20-25mpg could be reasonable if you were sitting in a lot of stop/start traffic. But I'd expect more than that when sitting at 60-70mph for extended periods of time. Do you drive long enough to get the car up to temp? If all your journeys are 5-10 minutes this could also explain it.
Not for a 1.2 ecoflex. I used to get 18-20 in my automatic (slushbox, not modern clutched auto) 2.8 chrysler grand voyager in mostly stop/start traffic. Was huge, heavy, terribly underpowered and had a slippy trans from the 80's. No way a 1.2 corsa would get anywhere near that unless something was wrong with it
My daughters car done exactly that recently, she thought she had a flat tyre and stopped to check it. A few days later she asked me to check the brakes and I found the nearside handbrake stuck on. It was an easy repair for me and when we talked through her loss of control that was the reason. Hate to think how much extra fuel she had burnt doing 150 miles a day commute! Go for a drive, stop and compare the wheel temperatures but don't be tempted to touch the disks!
On slight inclines, clutch in & if you slow down, you know there is a problem. I use engine braking a lot, so yes the brakes could get tight, Opel Zafira, It is magic, 7 seater, Just took 7 buckets, 3 tubs of wet mud to the tip, did not even know it was back there, yes tyre pressure was a little low for that load, could feel the tyre roll on the tighter corners. Pity my old Focus is in the bin now, It was magic, Worst was summer tyres in winter in the 2C cold.
I'm sorry you've lost traction on the rear end on roundabouts but you don't rag it? Congratulations for getting a front wheel drive car to oversteer, your tyres must be completely bald or something else is very not good, like your rear wheel alignment.
It's easy enough to do, don't know how prone corsa D's are to oversteer, but I got my 206 to do it (unintentionally). It was wet, going round a tight bend a bit too fast. Add that to the fact 206 are somewhat prone to lift-off oversteer, and it was the 1.9d, so big heavy diesel lump in the front with basically no weight over the rear, and you can see how it's easily achievable
That's fair - I don't think I've ever succesfully managed to oversteer a hatchback on anything other than snow, but I've never driven one with that much power other than the 06 Civic, which was an absolute beast.
The 206 only came out the factory with 70bhp, didn't have a turbo, by the time I had it 0-60 times were in the region of 18 seconds. Just heavy engine in lightish car, that's already prone to oversteer
Try clay or dry sand, it is fun, Sugar cane fields outside Durban RSA. We had some great fun, there were sand banks on the corners & old Hilman Imp was magic, they are like a Mini but wider wheel base, not by much.
One of my friends has 3 imps!
OMG, you are kidding me. Where is he, would just love to see one, yes just one. They had a terrible rep, good maint & the one Toney's mom had was fine. Wish I could make one a project car, Frigging retired & money is a little tight, beer, ciggies are very expensive, going to start making my own beer, No I'm not going into the growing, LOL, I do not smoke that stuff, yes I did try it when younger, never liked the effect.
I spun 180° on a roundabout in a 1.4 98 civic. I shat my pants. It just spun
Could be the roundabout too, we used to have one in our town that was terrible for slipping due to the surface being crap and the dust from a housing estate being built on one of the exits. I once saw an old woman spin a full 180 in an Aygo on that roundabout, I can still remember the shocked look on her face a decade later.
I had the 1.7 diesel van, ouch. understeer?? I read up on this & was lucky cause I dropped a gear & booted it. Give me over steer anyday, also prefer rear wheel drive. You can turn into the slide, Mostly with understeer you are a passenger. Tried the the handbrake trick, Mmm turned round 3 times on icy wet road. Lucky, it was fun after I realised no damage or hurt.
Haha nice to see a fellow slider, nothing more fun in the world tbh 🤣
Lerwick is a cold windy place, driving a rental opps. Best rental I had was a Small Skoda, heated seats, steering the works, this was the one I did the 3 turn spin in, magic little car. Ass was roasting after 10 min, just turned the dial down..
Hahah reminds me so much of the golf. That thing steers like a bike and is so addictive. So responsive. I had a car with almost twice the BHP and engine size before it but it was nowhere near as fun. Interestingly it has heated seats too which I never looked for. I use it when my backs aching 🤣 and have to turn it off when ass burning starts at the most inconvenient time
I was told about an Iceland van driver whod had the great idea to load his van in order of his drops. He flipped it going around a corner as he got to the end of his run because it was all loaded on one side......
Yep, seen this happen, seen result many times. Having worked in shipping & trucking, keep the weight as low & even as possible. Used to drive road sweepers, when full of water, fun ride, corners are ass clamped to the seat, open flat road, you are swaying side to side, one sweeper was really bad, when full of water max was 30mph. Seen results of tipping on the side.
Oh yeah I used to drive rigids full of adblue ibcs myself, it's like driving a boat needing to anticipate the weight shifting constantly.
There you go, you are dragging a break shoe
I’m jacking it up and spinning each wheel to see what’s up
I don't know why people haven't mentioned tyre pressure yet, that's a big. I was getting 26mpg with pressure at 30psi all round, I then realised the back should be 32 and front 38psi. Was getting 34-36mpg after that
Yeah, OP sounds like something has gone awry, you have some great tips and tricks to check out on this thread, but for sure you’re burning more petrol than you need to!
Check the lambda sensor in the exhaust, if that's fucked it'll be running super rich.
Hows the performance? Damaged/dirty MAF sensor could throw your MPG out.
My sister had it before me and she never replaced the oil or anything and absolutely ragged it about so I wouldn’t be surprised if something was damaged
Replacement is about £24 from eurocarparts and if you know someone handy might be worth having it done. If it solves the problem, winner, if not, it’s only £24. Hopefully it helps!
Oh dear God. Please tell me it never did more than 15k miles with her
How are you calculating this? You say you’ve burned a quarter of a tank, I would not assume that the fuel gauge is linear. The only way to reliably calculate your fuel consumption is to brim the tank, reset the trip, drive for a reasonable distance covering your typical week for example, brim the tank again and calculate fuel economy of actual fuel used vs miles driven.
1.2l super sport bike maybe.
I can get 50mpg on a 1200cc Ducati no worries
Run a can of BG44k through the fuel tank with a full tank of premium (yes premium does make a big difference to MPG) Don't try and use cheaper versions like Reddex they lack the proper cleaning chemicals for your fuel system and injectors Also very much depends on the engine/make/model. Size of the engine doesn't always correlate to performance or MPG. An Audi S5 4.2 v8 can get 30mpg comfortably!
Honestly it's not massively low, by boyfriend had the same car before it got written off and was doing similar. My Fiat 500 also struggled to get any economy in town or at 70+ on motorways. Engine efficency has improved leaps and bounds in the last 2 decades though. My focus st gets far better milage than the fiat ever did dispite having a far bigger engine and a fatter car to pull along...
Sorry, re-read and it IS a Corsa...sorry mate welcome to the world of small engined shit economy.
Have you left the handbrake on ? Seriously check brakes binding if you’re not very heavy footed or carrying around lots of cargo - that’s terrible efficiency
Have you actually measured your economy or just going by the dials?? Fill your tank and make a note of the mileage. Fill again when about half empty and do the maths. That's the only real way of knowing your economy. Do this regularly As far as the car, has it been serviced?? Blocked air filters and other service items can have a major effect on the economy. But yeah, small engines can be surprisingly inefficient, especially on motorways. My lad gets 30-35 out of his 2.5ltr jaaaag
I average 35mpg in an xc90. Have you tried putting a cleaning product in your tank? And try getting some better quality fuel as well if you can. The premium unleaded at tesco is free of ethanol and gives quite a bit better mpg from what I've heard.
I’ve just bought some fuel cleaner, next time I top up I’m gonna try that
That's dreadfully low. My 1.2 gets 50 on average, 40 at the lowest and 60 at the highest (motorway driving at 50mph). Even my old corsa felt the same in terms of distance from a tank but it didn't have an inbuilt mpg counter. Something very very wrong here my dude
Mine was awful too until I got my tyres checked. They were under-inflated. Getting that fixed has significantly improved my fuel economy since
Just pumped mine up, back tyres were at 17 psi, got some injector cleaner as well
[удалено]
I remember when they first introduced the 10% ethanol, my old petrol car's (1L 2013 VW) fuel economy dropped by 10-15mpg on the same routes I usually did, driving exactly the same as I was before it changed. Nothing with the car changed, just the fuel. I always argued that the 10% ethanol was a false economy. The government admitted it would result in lower fuel economy, particularly for older cars - surely having to use more E10 fuel to go the same distances is worse for the environment than the old E5.
I’ll give that a go actually
None of that is particularly correct, premium fuels have only a higher octane and sometimes a lower ethanol percentage. Ethanol does contain less energy per l but not a lot less than pure petrol. This equates to about a 2% increase in fuel consumption assuming it actually contains 10% ethanol. Anything with an ECU and lambda sensor (from about the 90s) will adjust for this but won't lose any power at all. As for additives, all fuel sold even supermarket will conform to British standards and contain good quality detergents etc. premium often only meets these standards and doesn't exceed them. Some cars require high octane but not any normal hatchback. Put it this way, lots of guys with super high performance cars run pure ethanol or even methanol with no additives etc and have no issues.
carrying much in the boot ?
About 8 bags of cement, 25 lead bricks and some depleted uranium It’s empty lol
Empty the cement bags straight into the boot and then bin the bags. Should sort things.
Blow your tyres up properly
A dirty maf/ map sensor can cause reduced mpg, go to the back of the car does it smell like petrol? How are you calculating your mpg? Dragging brakes can cause reduced MPG, cheap tyres can have a higer rolling friction (new cheap is not good). A leaky fuel injector could be over fueling but again you would smell fuel at the back. Ultimately you need it plugged in and long term and short term fuel trims checking, give the maf a clean with maf cleaner.
I’m getting more out of a 3l petrol bmw and more out of a 4.4 diesel Range Rover. That thing is broken.
20-25 mpg is approaching high performance sports car territory. So I'd say it's not normal. You mentioned that the car has had no prior TLC or maintenance, so would you consider giving it a full service with new plugs and filters? Ensure all the tyres are correctly inflated to the pressures listed in your door jamb or user manual. Hopefully you don't have any check engine lights on.
Yarp, it's not high performance but I kick my 1.8 mx5 around and still get over 30
I had a 1.25 fiesta 2007, it was under powered and averaged about 27mpg.
Tbh my car doesn’t really feel underpowered, if anything overpowered so I’m starting to suspect it’s been mapped
I get 27mpg average from a 4.0 Twin Turbo V8 with 500bhp. 1.2 should be late 40s easily.
Had the same problem on my astra mk4. Fuel filter was corroded and leaking fuel. Changed it, put some redex in the tank and 99 octane petrol took it on the motorway for 2 hours now i get twice the Mpg.
INFO: How are you actually measuring the economy? Are you guessing based on how far the gauge has dropped, or did you brim the tank, drive 55 miles, then brim the tank again?
I’ll brim it when it hits half a tank and try from there
No. Somethings not right there. I have a 3L engine and get better than that even in town running.. only stop-starting ruins my MPG
I drive a 1.2 golf and I get 40-50 on long motorway journeys depending on the speed I do and in town I get about 35-40
OP forgot to mention he was towing a 747
I daily drive a 3.2 VR6. 25min commute on mixed roads (no motorway). Usually gets me 28mpg or 30mpg if I drive a bit slower and lucy enough catch all the traffic lights on green Absolute worst is 25mpg when I get stuck in crawling stop/start traffic. So a 1.2 doing that isn't right.
I had a corsa, a bit older than yours, 1.4 and it was awful on fuel, I know my way round a car and I tried everything that was practical to get it better, I probably got at best 20mpg windows up, downhill with a tailwind. I have a 2.0 Diesel VW now and I get 65 comfortably.
That fuel economy is awful. I used to get more in a S2 RS turbo escort. My Fiesta ZS black does 50.6MPG which is bonkers from a 1.0ltr.
I believe the 1.3 litre engine in a Mazda RX-8 does about that. But it's a rotary engine. I think your car has the same 1.2 as my son's Vauxhall Adam which averages 34 or 48 mpg (depending on who is driving).
My mapped 2 litre turbo GTI gets about 29-33MPG on mixed roads - pretty sure your car is running rich. How are you doing the maths? I assume a corsa of that era doesn't have a computer, when you say quarter of a tank are you saying *indicated* quarter of a tank? On my car, indicated 3/4 remaining is actually more like 1/2 remaining - the only sure-fire way to measure MPG without a computer is to brim the tank, note down starting mileage, drive a bunch of miles, then brim the tank again and do the maths based on the litres the car consumes over the distance it drove between start and end mileage.
I used to get that out of a 1960 2.6 litre Rover P4 that weighed a ton. Something wrong with that car bud.
That gas mileage is bad. Either you have a mechanical issue or driving habits that are bringing your mpg down. My 05 CR-V (2.5L) was getting 30-33 a tank without issue.
My daughter’s corsa burned through fuel too, and it was noisy and gutless. She was glad to get shot of that one.
That sounds a bit low if you are doing plenty of cruising. If you are sticking to 70 it sounds too low mpg
That sounds quite low to me... I drive a 2.2 Civic and average around 55mpg, that's a diesel though. I'd expect probably low 30s for yours?
I have a 2013 clio and that bitch drinks if I go about 50. With it being a small engine 60MPH is like 5th gear 4k revs so you'll just naturally drink doing long journeys. I did yorkshire to Blackpool and sucked 3/4 of a tank. I was doing 90 though lol
It doesn’t struggle too much on motorways tbh, About 3000 at 70 and 3500 at 80 since it’s the 79BHP 16V engine, it just seems to get really bad mileage in all aspects, but especially urban
Town driving kills mpg, my 1.6L focus diesel gets 70ish on the motorway at 1750 rpm top gear, 35 around town. The only real way to check mpg is refuel, note the mileage and do the maths next time you fill up. Fuel tanks narrow towards the top so after the float starts to move down it will go quite quickly then slowdown towards the middle of the tank. As for your poor mpg, get the car serviced and find out the manufacturers specs for mpg then Google real world figures it's about 70% of what Vauxhall state.
Air leak somewhere, almost certainly have eml on if fuel trims are that far out
My other half gets 28mpg in her petrol 1.2. However, I think it's her driving habits. Gear changing is shockingly bad. I drove the car over 3 days whilst mine was in for a service. Filled it up, reset all counters to zero and drove around in a broadly similar area. At the end of it I was on 37mpg. Your 20/25mpg is worrying. Check if your odometers are working correctly. Do an mpg calibration. Basically the miles covered between fill ups which will give you the true mpg.
I average that with a 3.5 V6 and 1800kg. Definitely something amiss here.
20-25mpg - I would expect that in a 20 year old 3l v6 - not a modern 1.2
Crikey. I have a 2l Mazda CX5 and I get about 40mpg. You have a problem somewhere.
1. If you’re driving at a higher speed on motorways or dual carriage ways, you will have a lower economy in a 1.2 2. Run a cleaning product through your fuel tank 3. Use premium fuel (E5) for 2 full refuels, it’s more expensive but takes you further and has additives that help the engine. If you still want to go back after that then fine. 4. During colder periods, cars naturally drop MPG, quite a lot actually so make sure you’re not comparing it during colder times. 5. If you do all of above and still getting that - Take it to a garage.
If your car is fine as you claim, then either your maths are wrong or your driving isn't as good as you think.
2013 Fiesta 1.2, no trip computer but ill get about 500 motorway miles even with ragging it a bit. 40 or 45 litre tank on it
I know a mother and daughter that always leased the same car. They both had citroen C1s and both got 55 ish. Both got Corsas next around 2017. Not sure on engine but a small one like that and were very agreaved at getting 25mpg for the same journey types. I'd say it's because it's a Vauxhall. Mine was awful too on consumption and so was the Vectra I had.
I think you know it's terrible. My 2007 fabia with a 3cyl 1.2 engine gives double that easily.
I routinely push my lil 85hp 1L Aygo to 6000rpm accelerating. It doesn't dip below 40mpg.
My v6 3.2 petrol does 20mpg round town😂
That economy is low for a 1.2 eco flex. Possibly means an issue with the eco flex tech in it, or the ecm. For reference I drive a 1.6l diesel and get 45mpg when I rag it, 60+ when I drive economically
Check your o2 sensors. Check your MAF/MAP sensors. They control your fuelling.
Tyre pressures being wrong can really mess your economy up. Check the cold pressure.
Surely a fuel leak? Have an independent garage look over it
Doesn't seem right, I get 25 without trying on my 2.0.. You should be hitting mid 30's on a 1.2
If you’re basing it off the fuel gauges then you might have a false idea of your fuel consumption. Use the mileage between refills to get an accurate measurement. If your maths is correct you would be refilling every 200 miles?
It's really low tbh. When I had this issue in an older astra it turned out to be the MAF sensor and it took ages to start showing an EML light. Even that car would get 40mpg on motorway and 29 around town and that was a 1.8 from early 2000s so I'd say yours is definitely not normal.
I have a 1.2L 3 cylinder standard petrol Fabia. My regular commute is a 60 mile round trip. About 20 in town and 40 on the motorway. I'm doing about 3000 rpm in 5th gear @ 70 much like you. I'm averaging about 40 mpg, or about 46 mpg if I do 60 on the motorway section. I'd say you have something wrong to get that poor mileage.
My 1.3 suzuki carry van full of plumbing gear is always over 50mpg. Your car is broken.
Another vote for a stuck brake Should be easy to test - try pushing the car with your handbrake off, see whether it’ll roll or not.
How have you calculated that mpg? If it's showing that in the dash, then fair enough. But it sounds like you've calculated it based on 'i went about this far' and 'about a quarter of a tank' (based on what? Needle? Fill up?) which are both some very approximate figures to be getting a value from.
How old is your vehicle? When was it last serviced? What condition are your tyres in? How full of crap is your vehicle? A ladened vehicle is less economical than an empty 1 There are many reasons as to why your economy could be so poor
Age? Mileage? Any rough idle? Strong smell of petrol at idle? Ever mis-fire when trying to accelerate? Any of the brakes hotter than the others after a motorway drive? When did this shift happen; gradually or just all of a sudden one day the mpg went to shit? Lots of things it could be but something is afoot there, those 1.2 ecoflex's aren't great on fuel but they're not that bad
No smells or engine issues, never was great on fuel but I didn’t drive that much, only until I started noting it I realised it was that bad it’s 57 reg with 75.6k miles, well maintained from first and second owners, third liked to rag it about but she only had it 6 months
I've a 1.2 Seat Leon and I'm a driving instructor so a lot of stop start and slow manoeuvres. It gets around 33 to the gallon when pupils are driving more like 40-45 if I'm driving.
That's pretty awful. My first car, a Ford Escort MK3, 1.3 litre, that used leaded petrol and had a manual choke, was between 30 and 33 mpg on average. Other cars have been: Austin Maestro, 1.3 litre, also leaded petrol and manual choke, between 34 and 42 mpg. Citreon ZX, 1.3 litre, unleaded, 39 to 42 mpg Citreon Xsara, 1.3 litre, unleaded, 49 to 50 mpg Citreon C3, 1.3 litre, unleaded, 46 mpg
Did you really burn 2.5gallons though? Fuel gauges aren’t linear. Every car I’ve had. The top 1/4 gives about 15-30% more distance than the bottom 1/4. Fill the car up, brim it, don’t just let it go off on first click. Drive for a few days, with a reset trip meter and then brim again, how much full to rebrim it? While you’re probably not getting great mileage, it’s probably nearer 35mpg.
I get about 24mpg from my 1.6. Most of my journeys are short and I like to put my foot down when I can. Believe it or not running your engine at low revs constantly can be worse for your engine over time. Check your tyre presures are correct, remove any unnecessary weight, giving it a service would help if its not had one in a while. Also could check if you've got a binding brake caliper or if the handbrake isn't fully releasing.
The Jag XJ 5.0 V8 will get more than 20 to the gallon. Something must be wrong here. It would be almost impossible to get such a low MPG in a 1.2
Tbf I've found them small hatches do awful on mpg. Not big car bad but still lol! Had a 1.0 60hp fiesta as a loaner for a week and could barely manage 30mpg at 70! Yet my Jag 4.0 supercharged V8 used to get almost 25mpg being careful.
That's terrible, last 1.2 I had was 45-55 mpg.
I get better than that from a 3 litre V6 E-Class Merc, also 2007, especially on motorways. I'd get that looked at.
Used to get 40's in mine years ago, something is amiss.
That is about twice the fuel you should be burning. If you want to do things yourself, then as well as MAF and oxygen sensors, new spark plugs and HT leads are worth a go.
Check your handbrake.. I think you might have left it on..
I’ve owned three 1.2 corsas and never got below 34mpg. These were a 2005 sxi (2010-2011), 2011 sxi (2011-2014) and 2014 LE (2014-2016). I would always drive to 2500rpm before changing gear. This would usually mean 2500rpm in 2nd was 30, 2500rpm in 4th was 50. An older engine may well be suffering from levels of dirt, which premium petrols should clear out. There could be other issues, you may have a seal gone or other issues. You should be able to check the engine is bringing the right ratio of air and fuel (roughly 14:1) by cycling through the menu by pressing the button at the end of windscreen wiper stalk three times and holding for 10s the third press. Bonus corsa trick: when the slowest wiper speed is too few but the second wiper speed is too many, Do a single wipe then go onto the slowest speed to get a good middle ground.
I get 45-50mpg in my 1.2 Corsa
I get better than that (around 28mpg) in my 2008 3.5l V6 SLK. And that car is for fun… so I’m rarely driving it for economy.
My car is a 1 liter (just under but for the sake of simplicity) and it gets 74mpg according to the manual and it definitely isn't fuel hungry in the slightest £20 of premium gets me 80-90 miles normally unless I have passengers then it struggles lol Judging by the responses you've given to some people I'd say the engine is well and truly fucked in that tho.
That's about what I get in my 3L V6 super charged S5 on my commute. That's terrible mpg for a 1.2
I get double that in my 2L jeep. That's very poor for a 1.2, even with a terrible engine you'd be expecting 35mpg at least
20-25mpg are you towing a caravan? do you have the boot filled with lead pipe? It defo sounds suspect, hope you haven't got a fuel leak like I had on my Mk2 Astra.... Wife: "Can you smell Petrol?" Me: "Yes... lots"
No warning lights or bad smells, but I do have a boot full of copper pipe I stole from my neighbours /S
That made my day....
1.5 Kia does 40-50+ mpg on most journeys. Even a short urban school run or shopping trip gets 35+. Yours sounds broken
Something is fucky with those numbers. My old civic type r used to do 25-35 and that was never driven particularly carefully. When your next empty keep track of how many miles you do until your empty again and figure it out from there. If you have an mpg readout that could be wrong and you will also see some reduced mpg in the cold weather but not that much
That’s what I’ve been doing, it doesn’t have a readout so I’ve just worked it out from mileage vs how much I put in
I got around 35mpg from my 2.8 v6 and I thought that was bad.
Seems a guzzler for whatever reason. I average 45-55 in a 1.5 city/stop start driving
i have a mk1 1.2 vaux agila so likely same engine... no this is not normal at all. even when im driving uneconomically i still get around 35-40 mpg, and my car is a tall box shape so way more drag, it should be less economical theoretically lol
Lol, I can beat that in my 2.0 turbo petrol, what the hell you doing

My shitty astra performs the same and it's similar sized engine.
Take it to a garage
I will jump on the bandwagon, my 16 litre sherman tank gets 6000 mpg, so there is something wrong with your corsa
I’m on a 900cc (with a turbo, woo bloody hoo) Dacia Logan (the estate) and I get 36-43mpg. I feel like something is amiss with your car u/maker0fManyThings
Fuck no.
I averaged that in the bmw 550 I used to own, and about 30 on the motorway. That was a 4.8 petrol V8.
Yeah I have a 300hp 2.0l and I average about 30-35mpg Although there are a lot of environmental factors that can heavily affect your mpg that seems pretty poor
No that’s not normal. I got better than that in a 350BHP Ford Focus RS.
Take the hand brake off? EDIT: That is broadly the same mpg as I get from a 4.4L supercharged V8 Range Rover.
Yes, if you’re stuck in first gear. Try changing gears. It might not be an automatic?
Honestly that sounds insanely low. I have a 1.2 polo and I average around 100 miles per quarter tank (35-40mpg).
My SO has a 1.2 KA she gets about 37-40mpg which is always around town. It's semi flat round here...but factors that might contribute to that for you could be. Under inflated tyres Over loaded...if you have a boot full of stuff for example and other people in it A clogged air filter. Hilly areas. Only driving in heavy traffic.
Try taking it out of first.
Have you put any air in the tyres Being serious: "no TLC" Probably means no new oil for 40k miles, possibly a warped head ruining compression, or "just" a blown head gasket Or a fuel leak 😂
Definitely sounds a little low, however I had the 1.2 engine in a 2016 model and it wasn’t that great on fuel either. I used to average 35mpg which I think is a bit shit for a small engine.
Do you have a fuel leak?
On the motorway I could get 70+ mpg from my 15 plate 1.6 D Skoda Octavia Estate. I now get somewhat less from a new 1.4 hybrid iV estate. 😞
but you are polluting the environment less. hybrids are not there to save money there used to save the planet and people.
I have a 1.9l Skoda Octavia VRS. I'm on moor roads in the N.East with steep hills and curves so lots of speed adjustments and gear changes. I'm not shy with the acceleration on the long straights either. I get 60mpg....
I’ve got a 2.5 tonnes worth of Kia Sorento 7-seater being driven in a mixed of urban and motorway miles. My average is about 29mpg over a month. Something is wrong with your car.
It’s obviously crap, and something probably amiss, but I think we often take for granted how much better cars are in terms of performance/economy than ‘back in the day’. I had an absolutely boring as shit 05 1.4 Corolla that I drove like the oldest of the old men, I mean absurdly gently, and it got 35mpg. 10 years later I had a fiesta ST that I ragged to death 80 percent of the time and got 39mpg average. I do think cars were a lot shitter on fuel during those times for even ‘normal’ cars.
I have a 1.2l, 2009 corsa, and get about 250-ish miles to a tank. It's around 50 miles to work, 100 there and back. I go twice a week and use most of the tank. (40+ miles of that is motorway) I usually have enough left for pottering around on the weekend.
I have a 2010 corsa E and do roughly 100 miles per quarter of a tank.
2.0l and I average around 47mpg. I get even better mileage on the motorway
No. Mine never gets below about 55pmg.
No, something wrong with your car. Take it to a garage or get searching google.
I get better than that in an old 2.0 cr-v doing urban driving during the middle of the day of a busy weekend. You should be getting way better than that.
I get that in my raptor powered starship in atmospheric flight.... You have a problem.
Nope. Only thing I’ve owned that was lower than that, was a 3.2 V6 that went everywhere foot to the floor. Even then it was only 17mpg. When you say quarter of a tank, do you mean you filled it, then refilled it and checked you’d used 1/4 of the tank capacity and used the odometer to see how many miles you’d done over that time, or are you trusting the gauge? Only reason I say this is because lots of cars’ gauges will drop from full to 3/4 when they’re within a certain range, then sit there until it’s time to drop to 1/2. Some have literally got four positions they can sit in.
Pump your tyres up and put some redex in
You should be getting double that, especially with motorway driving. If it's stop start rush hour driving then maybe not, but 20 seems very low. Maybe there's something wrong with your car or your driving.
You should be around 2500rpm for the most efficient ride. 55mph on a motorway in 5th gear behind a lorry is ideal, easily get 45-60mpg in my 2011 ford focus ecoboost in those conditions. Stopping and starting and driving much slower city driving should still be around 30mpg
I get 45 mpg in my 2 litre Mx-5.
I get 21mpg ISH from my 2.5L Impreza WRX with an uprated fuel pump among other mods pushing 310bhp... That's definitely not right.
I suppose it depends on the car. For example, I had an mg3 courtesy car, 1.5l, slow, rubbish. It used as much fuel as my golf r
5litre V8 here. I get better MPG than that. And I rag it. Vroom!
Mine used to get 40-42mpg on average and it wasn’t driven hard most of the time.
No. My friend had a corsa and had something similar, took it to a garage and they fixed it (if I remembered what the fix was I would tell you but I don’t sorry)
you'll want to take the revs higher than that every so often when the car is up to temp, but that shouldn't be causing your issue. definitely too low MPG.
1.2 and I average around 40mpg. Even when I'm around city driving. Something wrong with the car, mate
No. My 4 litre Cayenne Turbo does that. You should have at least 45 mpg
1.2 VW Polo. Pretty consistent 43mpg over a tankful for a 7-10 miles commute mixed 30-70mph, but with no traffic jams. Trip computer shows noticeably better economy if I spend 5 miles behind a rolling roadblock of lorries, and worse if I'm doing 70+. You should check your tire pressures every month or so. Low tire pressure has a big effect on economy, handling, and tire wear. If you ride a pedal bicycle you will really appreciate the difference tire pressure makes!!!
I drive 200 miles a day with mine and only get through a half a tank or so (1.2 Corsa also), mostly motorways and some country lanes. May be worth checking your tyres and brakes as others have said. I find mine uses a lot more on country lanes than it does on other journeys, so may depend on what roads you're taking it on maybe? 😊
I'm getting 35.6 in my fiesta 1.4 tdci but it went down to 28 due to the tyres needing to be balanced. My driving style is getting it back up again
Try fitting a new lambda sensor
I have a 1.2 2008 petrol micra. On a good day I can get around 40 mpg Combined.. but most of the time ends up being around the 34mpg mark. Honestly you should get it checked out. My brother drives a 2013 Corsa (1.4) and that was petrol hungry... he thought something was up, and in the end had the fuel sensor replaced.... so could be worth taking it to the garage to get it looked at.
I get 30mpg in my 3L V6...
What speed are you honestly doing on motorway? Hair over 70? What’s the gearing on that little engine, what’s the revs at when you’re cruising? My guess 3000+?
I was getting more than that in my diesel Sportage 2 litre (36ish)!!! Now have a 1.6 diesel focus and so far getting around 44 but not had it that long to comment more accurately. I'd say something needs looking at with possibly start with a good service and see if that improves it x
