Thanks for your help guys bout my miles per gallon problem. Im really wondering, my car really pulls to the right bad, cause the alignment is terrible, how much diesel could I be wasting. Could I lose 200 miles of fuel from the wheels being that way. I do start my car, and turn off the car alot. Because I do pizza delivries with this car, could that also kill the fuel fast. How big is the Tank? 21 gallons? usually the light will go on, and when I fill the tank it fills 14 gallons how much fuel do I have left in the car? I just found also that my air filter is really dirty and im gonna buy a new one, could that also kill fuel mileage. Im thinking of buying the K&N filter it uses cotton instead of paper, is it worth the money to buy that.
