I bought my acadia used june of 09 . i drive back and forth to school maybe about 60 miles total a day and i have to gas up every two days. it seems my car just drinks gas or maybe im not use to it i was driving a 96 grand am and it was great i would gas up maybe once a week, driving the same route. is there anything other than tire pressure that i can check to get better gas millage?
