red58, people can say that all they want. I park at the same pump, write my mileage down and count. Ive down it several times in a row both ways. Always the same. I get 24 up and 29 down. Maybe a few decimal points off, but its true. It may be the vehicle aerodynamics??? who knows. I know it works in my toyota. Im sure I could nurse a few more if I took my foot out of it!

Also, I get better mileage using lower octane gas. Tried several times with the high octane and got around 21 mpg. Not sure how that works either but it does...
