03 "S" 19% ,headers, miltec exaust ,16" wheels,alta intake,jcw injectors,big intercooler,ect . The computer says 22.3mpg

 

I got 34 mpg on my first tank with the car.

 

We are getting ~32 city and 35 hwy with our 07' MC Automatic.
Would likely have a higher hwy result but this includes traffic pockets in
the SF bay area traffic commute. My wife primarily drives the car and she is
a fairly conservative driver.

 

I have recorded every drop of gas that i have put in my 03 cooper and after 58000 miles my cumulative mpg is 30.01

 

between 29 and 30 in town.. 33 hwy... 15% PULLEY AND K&N THAT COME TO THINK OF IT HAS NEVER BEEN CLEANED!

 

You asked for it ....

All data is hand calculated.

(completely stock; 16" v-spokes with runflats)

 

The best I've been able to get is 42 mpg (OBC). Average - 36 to 38 mpg combination city and highway. Gas mileage seemed to improve by a few mpg after 20,000 miles.

 

30.5 mpg average in my stock 06 MCS with stock (pirelli) 17" runflats and 20,000 miles. Almost all highway miles; trying to keep it under 80 mph.

 

When I can keep my foot off the gas at about 60 mph I average 34-35. In normal driving about 31. I find that I get better mileage with 89 octane than with 91-93, but the engine runs bettter and gives better performance with the higher octane.

 

7.4 MPG according to the in flight computer with 105 Octane fuel.

 

I get an average of 26.5 MPG. Almost always. And I calculate at every tank with a calculator and my gas (93 octane) receipt. I drive mostly highway in my 2006 MCS. I now have the JCW CAI and Milltek exhaust. I haven't seen too much change in fuel consumption since the mods were installed. I don't drive "too" hard but I like to get to cruising speed quickly. The best I ever got was 29 on a highway cruise with 60 other MINIs in the mountains. The worst was 24 as my car was breaking in.

 

29+ per gallon on first two tanks in new '07 MCS w/17" wheels.

 

I have been getting 29-30 miles per gallon with about 60% highway driving (stock Cooper with 15" tires).

 

I get about 35mpg on flat highway, 30mpg throught the mountains, 28mpg in the city, and average overall about 30mpg in general.
