I use it at every fill-up. It quiets the engine and it runs much smoother. my fuel mileage has increased an averave of 1-1.5 mpg. Havent really felt anything in the way of SOTP oomph. But, the extra mileage, cleaner fuel system and injectors is a plus. Great peace of mind, especially since I take 3 long vacation trips per year, towing my travel trailer. Its cheap insurance against clogged or dirty injectors.
