Hey everyone,

I got my new Cooper S a few weeks ago, and am still breaking it in. I have a lead foot, and have been getting those revs up to about 4k - 4500 after the engines warmed up. The onboard computer says that my MPG is 17.6MPG. I'm wondering if this is normal for an engine that is still breaking in, and someone with a lead foot like me? :p

So far, I've only driven in Mid mode as well.

Thanks!

As you've said 'gas' I assume US gallon so UK mill age would be greater but it still seems low, but the only way to see ifs it's a lead foot issue is to drive with lower revs.
4K whilst running in through the gears seems high if it's all the time.

I have the same model in the L.A. area and drive "briskly"
when I get the chance.
My dash readout shows 27 mpg average. The low end
torque is so good that I don't feel the need to buzz the engine.
If I drove more sedately and used the green mode I know
that over 30 mpg is achievable. Nevertheless, even staying
in sport mode and using 4500 revs, 17 mpg seems low.

Yes, I live in the US. I also forgot to add my Cooper S is an automatic with paddle shifters. I usually just drive it in "D", but do like going manual with it quite often. Yeah 4k - 4500 isn't economical I know, but it is fun to hear that exhaust and feel that pull :p.

It seems like i'm getting conflicting reports now. I guess I will just drive more "economically" and see if that helps. Also, how accurate is the onboard computer?

I have a Cooper S auto and I'm getting 25 mpg over the first 600 miles. I also have a BMW F30 with the 240 horsepower 2 liter turbo. It weighs 3,500 lbs. and gets 26 mpg. I think I drive them both the same with the auto stop/start turned off.

I was expecting the MINI to get better mileage, since it has less power and weight. Perhaps the 8 speed trans in the BMW compared to the 6 speed in the MINI makes more of a difference than you would expect.

I've driven 139 miles so far, and am on the first tank of gas still. I'm down to a quarter tank left. I don't think anything is wrong though, as there is no odd smells, sights or lights emitting from my MINI. I'm sure it's just that it's a new engine, as I've heard that MPG improves once an engine is broken in. I've been following the manual as much as possible to a T though about not going over 4500 RPM or 100MPH.

Still just sort of surprised as well at the 17.6MPG, even at those revs. I'm not complaining though as gas prices have dropped quite a bit around here. :D Might as well have some fun while it lasts. :p

1800 miles, manual MCS in the US. 29.5 MPG in city driving, almost no freeway. Sport mode 100% of the time.

You'll get better mileage once the engine breaks in a little better, but you might want to also reset your onboard computer's MPG counter. I usually reset mine every few tanks or so.

Hit the "BC" button on your turn stalk until you get your average MPG reading on your instrument cluster then press and hold the "BC" button to reset. It will start calculating from then.

I'll do this the next time I fill the tank. Thanks! :)

I was wondering about this today. I've gotten into the habit of resetting the dashboard MPG reading every time I fill up. I'm also doing the same, at the same time, with the trip computer that you access through the centre console.

Thing is, the readings are quite different. Nothing major, but usually about 4-5mpg off one another. I'm getting pretty low readings for a MCSD at the mo - usually around the 45mpg mark, so we're looking at a 10% difference between the two readings.

Does anyone know why this is, and which one tends to be the more accurate?

I consistently drive my MCS like it's stolen. shift around 5500 RPM. Traded in my 06' M6 for my MCS. V10 for 7 mile commute....ridiculous. MPG for me has been around 22 to 23MPG. I also have a VIP air intake, and a BMS B48 Stage 1 chip installed.

Your reduced MPG may also be attributed to poor quality gas. I prefer Shell, and settle for Chevron when I have to.

MCS 1400 miles.... Sport mode
1st 800 easy shift below 4500 rpms
Next 400 up to 5500 every now and again.
Soon as it hit 1200 miles.... Pretty much wide open all the time!
30-31 MPG

If you are still on the first tank, reset the onbaord trip computer and see what happens It could have been sitting on the lot running with no lileage which would push the MPG down. I have a non S and with less than 1000 miles I am averaging 43 in green mode Majority of my driving is highway

I just filled the tank yesterday with Shell 93 Premium fuel and reset the fuel consumption meter. I will be keeping an eye on this.

Mine was a custom order, so this could definitely be true. I also bet the dealership just filled it with any fuel from the closest gas station regardless of quality.
