    I keep pretty anal records on my vehicles. Below is the worst and the best I've gotten on a tank, along with averages for each year I've had the car.

    Date Gallons Miles Mileage
    25-Mar-04 13.979 247 17.669
    18-Apr-04 13.991 370 26.446

    2006 486.45 10576 21.741
    2005 834.51 18155 21.755
    2004 622.45 13252 21.290

    Both the best and worst were prior to any mods and it is almost always between 20 and 23 at each fill up. I had a 99 T/A that I bought new, it was an A4 and got slightly worse mileage. Even babying these cars and all highway miles I've never gotten more that 27.?? on a tank, that was on a 94 T/A with M6.
