Dissolves the sticky and gummy deposits formed by internal combustion. These deposits cling to vital engine parts inside the engine even after an oil and filter change. After using Penray Motor Flush engine oil will circulate freely to all parts of the engine, freeing sticky valves and rings. (Concentrated formulation is added to empty crankcase for complete and thorough cleaning. After engine is run for 5 minutes, drain Motor Flush, continue with maintenance oil and filter change.)
