Lauren Fix, The Car Coach Product Review: MAX-CLEAN FUEL SYSTEM CLEANER & STABILIZER


Royal Purple’s New Max-Clean is a state-of-the-art high performance synthetic fuel system cleaner that maximizes the performance of your fuel system. Max-Clean restores fuel economy and deeply penetrates and cleans injectors, carburetors, intake valves and combustion chambers.
