I bought your "Tune-Up" in a bottle Injector Cleaner two tank fillups ago and I've improved my "mile-per-gallon" by 7 miles per gallon. My new PT-Cruiser was getting only 18 mile/gal in the city before adding your fuel treatment and now I'm getting 25 mile/gallon!! I can't wait to see how well it does on freeway driving on a long trip, I'll let you know.
Thanks for a great product.
