Product Description

The Liqui Moly 2037 Pro-Line Engine Flush is a specialist treatment designed to clean the internal oil-system of engines without disassembly. Over time, oil passages, crankcase surfaces and lubrication circuitry accumulate sludge, lacquer and residues that hinder performance, increase wear and reduce engine life. This flush dissolves those deposits and restores proper oil flow before a full oil change.

Simply add the 500 ml can to the warm engine oil, let the engine idle for approximately ten minutes, then drain the oil, replace the oil filter and refill with fresh oil. By using the flush prior to the oil change, you help ensure the new oil works in a clean environment, maximising its effectiveness and protecting your engine. Ideal for both gasoline and diesel engines, this product supports smoother running, quieter operation and improved longevity.

For best results, use at scheduled service intervals, or when signs of internal contamination appear (such as engine noise, poor oil circulation or increased deposits). Always follow your vehicle manufacturer's service and oil-change guidelines, and ensure the engine is at normal operating temperature before applying the treatment.
