MILEAGE is really poor especially at $2.59 a gal here.

I get about what you're getting and am not complaining. It's only 2mpg less than I was getting with my 94 2WD 5-speed. I DID notice that my mileage dropped 2mpg when I filled up at a Pilot truck stop in Florida!

My 3. 73 ratio gets 18. 5-20. 5, But my friends 4. 10 ratio averages 14. 0. I also run Lucas Oils cetane booster (like octane booster for gassers) avaliable at most truck stops.
