NAPA Know How writers recently cited twice-annual use of Max-Clean in gas tanks as one of the “10 Overlooked Services that can Extend the Life of Your Vehicle.”

Highly versatile, Max-Clean is EPA / CARB compliant and safe for use in gasoline and diesel engines including all ethanol blends or biofuel. Max-Clean is great for use in both 4-cycle and 2-cycle engines, and will not harm specialized emissions equipment.

Fuel system cleaner is worth it. We performed multiple product fleet tests on various makes and models of vehicles and, after as little as one treatment with Max-Clean, we found significant advantages in engine performance and fuel economy.
