Use major brand gasoline regular, not "no name" discount gas. The key however, is conservative driving: No hard accleration, no 75 MPH highway drivng. Remember, air resistance increases proportionately to the square of the speed. Double your speed and you quadruple the air resistance. It takes much more gas to maintain high speeds. Coast to red lights, don't race up to them, then slam on the brakes. Almost all of the kinetic enrgy driving up to the light with your foot on the gas is wasted by transforming it to heat through the application of the brakes. Maintain good tire pressure. I notice a drop in mileage as soon as I take off the alloy rims with summer tires and put on the after market steel rims with the clunkier winter tread tires. Also winter gas formulation changes and just cold engine in cold weather changes fuel mixture, and gums up the drive train, so expect a drop in mileage in the winter.
