This problem you're having seems to be strange to me... Out of all of the b5s that I have had, and worked with, this number does not sound right. My gas mileage on my 1999 B5 1.8t (AE quattro, 5spd, averages from 25.2 to 31.1 depending on what and where... It may deviate a couple of miles depending on oil life. I only have a cat back exhaust, and intake. BUt thats it. I have always been impressed by the fuel consumption, so your problem puzzles me... This is with 91octane shell gasoline.
