Complete Engine Treatment

Lucas Complete Engine Treatment is a multifunction cleaner plus lubricant from the labs at Lucas Oil Products. It is designed for use in both crankcase and fuel system and works in both gasoline and diesel engines. When added to fuel, it cleans and lubricates all components from the fuel tank to the cylinders. When added to the oil, Lucas Complete Engine Treatment cleans internal engine parts and forms a protective barrier against excessive heat and friction while extending oil life.
