on my drive up to school when i first got a tank got me 275miles of straight up highway, no city at all driving around 75-90 the whole time, so around 170 city is about average for an auto gt? up here at school the only driving i do is in the city since all i drive to is school and stores and what not...except for the occasional joy drive to wherever

Hell 170 aint average for an auto GT, before I changed my fuel filter I got about 270-280 miles per tank and at least 50% of my driving is around town (speeds up to 55-60).
