Worry may have been the wrong word.. I guess I am aware of my mpg too. I just don't care what it is. I bought it to drive it like I hate it!!

Your mileage for the Audi matches that of my 1998 Suburban 4WD...With a 42 gallon tank, and since I don't drive all that far, I only fill it up every 4-5 weeks. It only bothers me when 3 rounds of cars come and go at the pumps and I am still filling the truck up.
