Description
The LIQUI MOLY Pro-Line Engine Flush (Part #2037) is a highly effective formulation designed to quickly and safely remove deposits from engine components before an oil change. This specialized product optimizes oil consumption, guarantees proper oil pressure in hydraulically activated systems, and ensures optimal oil flow following a cold start. Its advanced cleaning action allows the fresh oil to develop full performance immediately, restoring engine efficiency and reducing exhaust emissions. Suitable for most 4-stroke gasoline and diesel engines, Pro-Line Engine Flush is tested safe for use with catalytic converters and turbochargers, making it a versatile choice for a wide range of vehicles. To achieve the best results, a minimum of 3 liters (3.17 U.S. quarts) of oil is recommended for use with this product. A single 500 ml can is sufficient for cleaning up to 5 liters (1.3 gallons) of oil, simplifying maintenance procedures and delivering excellent value. To use, add the product to the engine oil at operating temperature before an oil change. Allow the engine to idle for 10 to 15 minutes depending on contamination levels, then proceed with the oil and filter change. This process ensures thorough cleaning without damaging seals or components. The product is compatible with most commercially available engine oils and is suitable for use in oil-running belts. Please note, it is not recommended for use on motorbikes with wet clutches. The formulation is environmentally friendly, does not attack common sealing materials, and is suitable for diesel particulate filters. Its gentle yet rapid cleaning action makes maintenance simple and effective, enhancing engine longevity and performance.
