My 09 MCS with alta CAI, 3" exhause from the DP back will average 40-44 MPG with the cruise control set at 63 mph. Keeping it around 75-80 it is around 30-34mpg. With it running hard on the autobahn average of 140mph and up I see around 9 mpg.

 

Here is an image of my current mpg. I'm driving mostly for mpg on this tank but I still have run it up through the gears W.O.T. 2 or three times. From the inaccurate computer, it shows I'm going to get about 617 mph this tank.

That's very interesting!! Can you tell me how you brought up that info. on the Radio Display?/!!

 

RJK, I'm pretty sure that '07 and up MINIs have this same comuter. Just press the menu button next to the button which has audio on the other side of it. Then turn that button left or right to tab on computer. Pust the button and there you have it.

 

When I bought mine it was at 30. Then I installed a CAI and Riss Racing exhaust and it went down to 23. Then I reinstalled stock exhaust (RR too loud) and it stayed at 23. Then I installed a scorpion exhaust, disconnected the battery and now it shows 30 again.

Thanks much!! I'm not able to drive her right now, but in 8 Weeks I should be able to. I will definitely have to see if Molly shows me this info.

Thanks Again!!

 

We average 34mpg with alot of in town driving and some highway.. Agressive driving at that.. 2009 justa with 6 speed.. Have got 31 if i rip the hell out of it.

Man, i thought we should be getting better than that but seeing some of these numbers makes me glad to get 34

 

Why can't we have the Autobahn here?!?!?!

 

With numbers like that you must be driving downhill the whole time

 

Nope.. It is about 10 miles from home to work on country highway (50mph) then about 2 miles through town (9 stoplights and always hit every one) then about 15 miles from work to school, same stoplights, then about 6 miles to the house.. that is with the wife driving and she is harder on it than i am.. Granted there arent any hills.. Mostly flatland here in central Indiana

 

I have about 900 miles on my '10 MCS and my recent avg MPG (based on tripometer math) is 25. My daily commute is a 50/50 split of highway / street. I usually have the A/C compressor turned on and I have a fairly heavy foot but have been keeping it under 4500 RPMs during break-in. I'm thinking my avg should go up a bit after time...I'd love to see ~40 MPG at some point.

 

I don't think I've ever gotten above 35 mpg on my MCS. I doubt you'll ever see 40 mpg. I don't recall my mpg going up much after break-in.

 

My 08 MCS 6-speed manual gets a steady 34.5mpg on my 5 day a week commute. 60% HWY/40% city. 100% Freeway gives 37mpg. All Calcs done by hand. The OBC consistantly reads 2 mpg high.

 

My '08 MCS gets 33.2 avg with about a 30/70 split city v highway. It's been fairly consistent since I got it.

 

after 3 days of ownership and commuting, my 08 MCS 6spd shows 42mpg (on board)...my commute average speed is 52mph...no freeways...just a few stop lights...27 miles each way.

I just filled up for the first time so I'll get a more accurate hand calc method in a couple of weeks.

 

I just filled my 2010 Justauto for the third time and my computer was indicating I had gotten 33.5 MPG so it seems to be about 2mpg optimistic. I have two Acuras and their milage estimates are spot on so, how hard can it be to make one that calculates correctly?. My calculation based on the fill-up was 31.5 which is still not bad considerering I have less than 1,000 miles and the EPA sticker says 28 combined!
Question: Is anyone running 87 octane? The manual says you can but, was wondering how it effected the milage. I may try a tank in the future as premium is almost $3 here in Nashville.

 

I just did 36 in mine. computed by hand. OBC reads about 2-3 miles high.

 

Best I ever got was 33.5 on an 1800 mile highway interstate trip to Denver and back. In town it's 28-29 mpg.

 

I just finished my first tank of summer blended fuel and got 41.5mpg, (all highway driving, 60-70mph, ac-off). I'm having a JCW tuning kit installed on Monday at NW Mini in Tacoma, Wa. I hope I don't take too big a dip in MPG's.

 

interesting - I think I'll; go check my numbers... ??

 

That's close to what I'm getting. I could drive for better mpg if I really wanted to but that would give MINI a bad rep. Also, I wish I was getting a JCW tuning kit. I'm sure that you will only get worse mpg if you get on it because the engine becomes more efficient.

 

6 speed MC here; average 36mpg city. Around 50 on highway.
I shift around 3k RPMs and keep it in 6th if over 45. Rarely use the AC (providing weather permits).

Lovin' it!

 

I get 24 but I do a lot of spirited driving and some traffic on my daily commute. Id say about 60/40 City/Highway

 

I average 29MPG city everytime I fill up I check. I used to get 33mpg city driving until I start modding. Highway depends, last time I took a trip on highway driving I averaged about 37.

 

i still get 24.4 mpg
=(
maybe my MINI loves eating up gas?
