Yes I do, alot of the time. I usually do around 80 on the highway while my dad does 90-100 and we still get great gas milage. I would say 80% highway so that might help. I call it luck. maybe 93 octane gas helps

13 average for me.

20.4 is impossible if your car is turned on.

In the middle of no where it is quite possible.

I do the math at the pump, not much for the propaganda that the OEMs use for mpg in the car.

2200 miles on the odometer, have not had any tank below 18 mpg. My trip computer is reset after each refill and hit above 20 most of the time. Back country roads! I have not however averaged above 21 mpg yet!

Most people here just go by what the fuel meter shows. They dont realize it can be 10 to 20% off.

I calculate how many miles driven plus how much gas put in, and I get about 17-19 with a mix of city and street

not bad imo for a car like this

I used to get the same in my 335i, though I hit boost all the time back then... lol

I get about 20mpq in my Z4

13-14 around town after break in. 17-19 on highway between 75-90mph.

Saw a nice bumper sticker on the back of a big pick-up a few years back:

" Suckin' gas & haulin' ass "
