Hey guys and gals. Ive been wondering some things about my MPG. I sold my old Mitsubishi mighty max pickup which seemed to get bad mileage. I could watch the gas needle go down as I drove lol. But anyways, i gave it up so i could get my beautiful 25/37 MPG cobalt. Well the dealer gave me a tank of gas and it only lasted 220 miles:weird:. Since then, I drive it and it seems the old way of my truck, I can see the needle go down like have a notch before i get home from anything. It has 1447 miles on it and ive filled it up like 13 times!
