I have had my car for a little under a year now and I've noticed that in city driving, my car only gets a brutal 10-12mpg. Highway driving is a totally different story. 40mpg. I recently got 496 miles from a full tank, on a highway drive. I'm just curious as to how many miles have you gotten out of a full tank strictly on highway drives.

Add that to your "Mein Auto".
Something doesn't seem right. 10 - 12 mpg is too low for city driving and 40 is outrageously high for highway. You should be getting about 21 - 26 mpg overall. How did you make your calculations?

I wouldn't trust the readout. You need to fill the tank, zero out your trip odometer, and when you need gas again, fill the tank, note the gallons it took, and divide that into the miles on your trip odometer. Keep doing that. Over time, you will get a sense of what your true gas mileage is.

23 to 28 for me depending on what kind of driving and that's with awd, so I'll take it... Could probably get 30-32 outta the right tank of gas and just going about 78mph straight down the interstate though.

How many gallons did you put in?
Unless it was all downhill, that would be unlikely to go 85 mph and 42 mpg over 200 miles. I would suspect there's something going on with the computer's calculation
Although possible, you might also want to do an odometer check and see if 1 mile actually equals one mile. Even at 490 miles with 18 gallons of fuel is 27 average mpg. With 16 gallons, still only 30.
The variables are obvious and were mentioned in this thread.
BUT if you are constantly resetting, you will be getting some absurd numbers. If you reset and do your city driving you will be picking up the really low numbers. NOTE: if you look at your MPG (instantaneous) gauge, you will see some cases of "0"MPG, and cases of "99" Mpg.
If you reset, then drive on the highway, you will be getting absurdly high numbers. The only way to test would be as noted by dividing actual miles by actual gallons used.:thumbup:

If you know that you will not be doing any highway driving for a few days, you could conceivably get your city mileage by zeroing out the trip odometer, filling up, doing your city-only driving, and then fill up again, noting the gallons and miles traveled. I think it's more accurate the more miles you travel, but it should at least be in the ballpark.
At 16.5 gallons, that makes it 29.7, not 40. Looking at the needle is subjective, if you only look at it on down hills or while not accelerating.
29 MPG on highway is good for your car. Do the division next time you drive street only, you might find out you're getting 20MPG. I get ~19.5 on my 535ix
