You need to take the number of miles you've driven and divide that by the number of gallons you used. That is a number that actually means something. 200 miles a tank could be anywhere from 13 to 19 mpg depending how your fuel gauge reads. Find out the actual mpg number and THEN compare it to the numbers posted in the MPG thread which can be found from a link in the consolidated sticky.

Probably 75% city driving for my 02...around 220 miles per tank, sometimes more, sometimes less, depending how much city/highway and how much playing I do.
