Has anyone used acetone...1-3 oz. per 10 gal. of gas...to increase gas mileage? Are there any rubber parts in the fuel system that would get eaten by the acetone?

 

This has come up many times on many of the Rover forums and I would suggest you stay away from it.
What sort of mileage are you currently getting, how many miles on your truck and what have you done so far to improve your mileage.

 

i HAVE USED NOTHING EXTRA AND i GET 21.7MPG ON THE 2008LR2 and 22on the Freelander. I watch tire pressure and drive conservatively.
What do you suggest?
