What's your best? I know you can manipulate the numbers by accelerating then resetting just as you let off and coast ( I got it to say 99.9) but what's your highest highway MPG?
You left out an important parameter. Over what distance are you reading mpg?
The best my 328i has done over a 250 mile tankful is about 33 mpg, normal is closer to 29 or 30 for highway driving and 24 overall.
And do you have a turbo or NA motor? It makes a difference.
