keep ur Transmission in Overdrive all the time. Dont drive above 55mph. Keep tires inflated to 35 or above psi, new air filter, pcv, plugs, wires, caps, rotors etc. Even when my low fuel light comes on and i fill the tank, I am only able to get 18 gallons in the tank. I heard this car as a 21 gallon tank. I dont think that is correct.
