I KNOW this helps: Wax the **** out your car! I did a test with my truck and long story short, with it waxed real good ... I got 3 MPG (hwy miles and city miles) more than with it washed only. I am going to do another test with my car as soon as I can get it aligned. My A/C kills my gas mileage too, so don't run it when you don't have to ..... Um, thats all I can think of.
