only 300?! thats nuts! im 17 and i do like 1800 a month lol and i dont even commute anywhereHow much of a difference does it really make? I always have put 93 in my car, but if gas goes up to $4 a gallon I'll have to start putting the regular in the car--I'm 17 and don't want to spend all my money on gas. I only drive like 300 miles a month or so, most of it in town. Bone stock 2009 GTI.
