A highly effective formulation designed for quick and safe removal of deposits in engines before an oil change. Optimizes oil consumption, guarantees proper oil pressure in hydraulically activated systems and ensures proper oil flow after a cold start. Allows the fresh oil to immediately develop full performance while restoring full engine performance and reducing exhaust emissions. For all 4-stroke gasoline and diesel engines, with or without turbochargers. Miscible with most commercially available motor oils. Safe for use with catalytic converters and particulate filters (GPF/DPF). Contents (500 mL) is sufficient for 3-5 Liters (0.8 gal. to 1.3 gal.) motor oil.
