I reset my mpg display before leaving work for the first time on my new to me MCS and averaged 41+ mpg for my 35 mile commute.

 

I get about the same if my mind is not in "race mode"

 

Is it highway all the way? I have yet to break 29!

 

Enjoy it...before the averages get you After a couple thousand miles without resetting the display, maybe more, I average 36.2, mostly highway driving, using 91 octane gas.

29 mpg? Sounds like lots of city driving, little freeway. I'd check my tire pressure. I thought Texas had 93 octane, and if you use that I'd think it would give your mpg a lift.

 

Do you have you display set to British gallons, seems high for a msc.

 

I've had the gallons spontaneous change to British gallons, you do get surprisingly high mpgs that way.

I also had British gallons when I didn't realise that setting British English in the configuration would make him use British gallons. I was trying to work out what changed when you set him to British, now I know.

 

I am, and always have, used 93. Funny, I've reset the ECU by disconnecting the battery, and my MPG has actaully gone up about 2 MPG, and I'm driving it harder now then before the reset. That's what has taken me near 29. Prior, I was only maxing out around 27-28.

A lot of stop and go traffic. I guess I'll just have to be happy with my 28-29.

 

Haha same here...I've been in race mode for the past year now lol

 

I've found that my OBC mileage reads a consistant 2mpg higher than My mpg calculated by hand. My 08 MCS is averaging 34.5 mpg figured the old fashion way.

 

I really gotta stay off the go pedal. Most weeks I average 25-27

 

I ave about 29-30 mpg with mixed driving figured by hand.

 

My OBC is always really close to my calc by hand, usually .2-.5mpg less actually. I get 32 mpg mixed.

 

Averages are tricky, too. I do a lot of releatively short trips and before the engine gets up to operating temps, mpg is not that great. On longer trips, or discounting the warm-up time, my manual Cooper does fantastic!!!

 

i can NEVER manage thta milegae...

 

Yep same here.

 

No not all highway it's a mix.

I don't think it's set to British gallons. How do I tell? I have searched through my owners manual and I don't see where I can check/change that setting.

Yes I do expect it will go down if I don't reset for awhile. But if I can maintain 36-38 I'll be happy. Thats a lot better than i was getting with my last car.

Has anybody found any cost effective mods to help with the mpg? I know I can do exhaust and intake mods to help but they will never pay for them selfs.
