^^^ Maybe your bad MPG is because of your SES light?

If I drive it hard for a tank I'll get 10 or 11. If I drive normal 15 or 16. Super easy and highway about 17-20.

Got up to the 20s on the highway but right now it's 15.7 city

[shoei]

i used to average about 9-10mpg in the city... but, 1. i used to drive it like i ride a motorcycle and 2. Los Angeles. Stop and go, all day long...

I'm getting 18 right now over a few thousand miles. A lot of it is highway or easy backroad mileage.

[S65V8]

Track : 6.2
Highway (Best) : 22.0
City (Best): 14.5
Regular Mixed : 13.7

how im i getting 9.4? i keep it under 5rpm...

[Crypty]

6mpg and that's as low as it will go I think. I reset the meter right before an autocross run.

[cohenfive]

my life to date is 19.9

[SouthShoreM3]

I was getting 12 steadily...since I supercharged it has gone up to 16!!!! Oh wait that's cause I'm still breaking the charger in...

I think we all know we did not buy the car for its gas efficiency.. My DD TTRS on the other hand will do 25-30mpg all day long and at worst 19 with a heavy left foot! I guess I actually did make a practical decision for once in my life when it comes to cars!

Ill just keep telling my girlfriend and myself that for a little bit longer..

just a cheerful note here-this may have been covered earlier in this long thread,but in my car if you actually calculate mpg (miles divided by gallons),it's about 1.5 mpg less than the reading in the dash display.i've checked this 4 or 5 times,always the same.are others having this experience?

last fillup,car said 14.3,it was really 12.8.

I get the same...computer says 18.5 to 18.9 and I'm usually right at or a little under 17 mpg actual.

i suspected that it was the same for others.so the moral of the story here is don't actually figure your gas mileage out,and then you'll feel better. i don't really worry about it,i knew the car would suck down lots of gas when i got it,but it has been a bit worse than i thought.oh well, must pay to play,this engine is well worth it,it's an amazing piece of engineering.it does make me wonder sometimes when i see something like a 500 hp two ton+ bentley that's almost as fast as an m3 and gets as good or better mileage.

17.4 mpg before supercharger....
After 10,000 miles, 17.3 mpg

[WayneM3]

I live in NYC and commute to Queens and my usual tank average is 10-10.5. I have seen as low as 9.8. With some highway driving it quickly goes up and in all highway I have seen just over 20.

[saeedg48]

8.0 in the AMG 11.2 in the M6

[Accelerometer]

Reset the clock at the last track day and got 7 mpg.

thats about right. i got 6-7 usually in the e90 and now high sevens to low eights in the e46.

[Ezio]

Right when i got my car new. I was getting like 9 MPG, and thought there is no way this car can be that bad. after more driving was getting 16MPG at my best, now 15.8 MPG.
