Yups, its another Cooper MPG rant!

I have just been browsing the forum, and noticed a thread regarding Cooper S comp, thread, to see who can get the most out of a full tank.

Now, They is a few on their who are getting (according to the trip computer) 400-450 miles! per full tank, for a supercharged 1.6!

I have a standard 1.6 cooper, and when I fill up a full tank, my computer averages around 300m, but I barely get that, more like 250, My mate has a Type R, and I am getting the same as him give or take.

I have tried everything, changed induction kit, tried different after market ones, then to revert back to the standard (it does help a littled) I have had my Oil service done etc.

Trying to do tests, for say a week after I have filled up full, to drive slow, no high revs, heavy breaking etc. But all fails. I can never get over 250ish to a full tank. I get about 50-60m per quarter on the clock.

When I had my warranty back in the day, I booked it in for them to check it out, but they found nothing, so doing that again would result in a heavy labour fee, for something they cannot sort.

I was wondering if they is any advice anyone can give me, maybe point me in direction of a previous thread/articles that could be of help. Anything Im willing to try.

Thanks for reading, and sorry for another MPG thread.

Maybe a petrol leak?

Also i see you have aftermarket wheels on. That could affect MPG if they are big/heavy.

You should definately be getting more miles than 250 to a tank,

On this tank im at 280 atm and that leaves me with just under half a tank.

[Mull3t]

Before I put the wheels on, I had the standard alloys and still got the same, has not really made a difference.

I have checked around for leaks but nothing, Im close to pulling my hair out! lol

[RichTea]

Have you got a trip computer, if so what MPG is it showing ?

I have a cooper '03 and the trip rarely shows more than 30mpg, although I only ever really do short stop start journeys, which are the worst kind of trip !

What sort of conditions do you do driving in (ie, stop/start, motorway etc) ?

Cheers,
Rich.

Yeah, the MPG it shows is usual 25-30.

I have varied in what I test out, for example I have filled up a full tank when going on a road trip, I.e down to london, or cornwall, and I get prob a bit more at around 280-290 to a full tank.

During the week I drive about 15 miles a day, to and from work, which is mainly on A roads, but sometimes I have opted to jump on the M1 to my Junction, but this seems like it uses the petrol more.

Mainly sometimes my day can consist of stop start. The thing that baffles me, is that other peoples with coopers, their computer says 400-450 to a full tank, Mine never says this

Hmm, I would have thought that a 15 mile a day journey on mainly A roads should give you more mpg than you're getting but I'm not sure how much more. I don't think I've ever got much more than 300 out of a tankful, even driving sensibly on longish trips. I'm not doubting that some people may have got 400-450 out of a tank but I would imagine that would be difficult (unless you travel everywhere at 56mph, not using your brakes and staying in the highest gear for about 400 miles).

Obviously I only have an '03 so I can't comment on 2nd gen MINI's, but the MINI despite its size is not that economical unfortunately. If you do that many miles it may be worth thinking about a Dooper ?

Obviously if you do find a magical way to up your mpg let me (and probably countless others!) know,

Cheers,
Rich.

I dunno what else to try
Its not the fact so much that its leaving a hole in my pocket, its just annoying the fact thats its a 1.6 and is leaving a hole in my pocket lol. I could have MCS and get the same MPG.

I have been looking at the MCS, but im not thinking of making that jump until early next year.

I think im gonna get it up at the weekend and have a full check out of it, engine bay, underneath etc.

I barely get 300 m/tank too man, mines a 53 plate cooper, but mainly town and stop start, and i cant help pushing 1st gear past 4000rpm cos i love the sudden boost you get so i dont really expect much better myself, only filled up last week, 1/2 left already, guess I will get getting another vpower ferarri soon then, every cloud and all that!

I think wiv a MCS you would get a lot less mpg, but have may have a bigger smile on your face

Yeah, I honestly think sub 300 miles is nearer the mark for an average Cooper rather than the 400-450 you are trying to achieve.

I know its difficult with petrol prices racing up as they are but I try and forget about MPG and drive the car as you want to, cos soon it will be too expensive to drive anything other than a 1000cc eco car and you'll regret not driving the car to the max when you had it !!

06 Cooper std spec.
On a recient trip to Scotland, I filled up 3 times using different petrol each time. First was Sainsbury's ultra low sulphur petrol rating
95 octane.

The computer gave a range of 389 miles still about 45 miles on the computer range but only 1 segment on fuel gauge (chrono pack gauge).

I refuelled with Tesco's finest, 99 octane the computer gave a range of 459 miles. Without making any adjustments with fuel supply's uncertain.

I refuelled with Shell V power 98 octane this gave 411 miles range.
Overall I averaged 37.1 over 800 miles mixed driving, with no air cond. on driving motorway speed as much as possible.

About 370 miles to a best estimate
Has anyone driven closer to zero on the computer range?

I wouldn't of thought the octane rating makes any difference to the predicted range. The trip computer decides the range by making a calculation of the amount of fuel in tank and the last recorded MPG. So if you cain it just before you drive into the garage and computer reckons you doing say 30mpg then that is the last figure it will calculate the range with. Same vice verser if you bimble into garage then range will be greater as mpg higher.
As for my mpg i usually get 300 miles before red light comes on and this is short trips to work of between 6 and 20 miles on A and B roads. This last week however i have been away on a course and travelling 92 miles a day on mixed A,B,motorways and have got 372 miles on tank with the range saying 40 miles till empty. Wanted to get to 400 miles but bottled it as im not sure how accurate trip comp is.

When I had my 04 Cooper it did around 28 mpg around town and on a run about 34, the highest I ever saw was 36-38mpg. I was using V Power as well! So your not going to get any better I'm afraid.

Unless you get a R56 Cooper your not going to get fantastic mpg, if you had an R53 S you would be lucky to see 25 mpg. hth.

btw, when changed from 15 to 17" S Spoke, it did effect the mpg the above figures are what I was getting with the 17"s on , but I was only ganing a couple of mpg with the standard 15" without runflats.

Hello Tracie

Amazingly, I'm still getting a long term average of 34 mpg out of my R53S!

[*Vikki*]

i have got a ONE and only get about 300 miles a tank, and i dont drive hard at all

[David King]

Over the last 800 miles ive averaged 42.1 mpg, getting about 370 miles until the light comes on.

All outside lane motorway cruising speeds.

[Joiner]

I drive 60-100 miles a day in my 2nd gen cooper and I average 30 mpg. My Citroen C2 1.6 16v was exactly the same. Have you checked your tyre pressures coz I gained another 2 mpg after pumping mine up.
To be honest you've just gotta accept it or buy a lower powered car.

[jpw]

Hi

I'm getting on average now 35mpg - gone up just recently since I had my seized rear calliper done - was previously only managing 28mpg - never realised it would make such a difference!
I would say thats about as much as you could expect from a cooper?

Jon

[Mull3t]

Never updated this thread to tell you guys the outcome,

Well I did a few inspections myself, and I have improved my MPG by a shed load!

Just simple stuff really helps out, I was running around 30PSI in my tyres, and I noticed when I checked the PSI one of my tyres was as low as 25! so I have upped them all to around 35psi and now I am on half a tank, with 191 miles used, and 234 showing on the clock. My MPG is also showing 35.7mpg.

Yup, and that has seemed to have worked. Its not that I cannot afford the money it taking, Its just I might as well go for a higher powered car (cooper s) and get the same.

But Now Im happy for the moment with what Im getting
