Liqui Moly Engine Flush is a concentrated, silicone-free liquid formula designed to clean and flush out the internal oil system of both petrol and diesel engines. Ideal for use before an oil change, this powerful treatment removes harmful deposits from lubrication holes, oil screens, the piston ring zone, and other vital components—helping to restore optimal engine function. One 500ml can is sufficient for engines with up to 5 litres of oil. By eliminating internal build-up, it can help reduce engine noise, lower oil consumption, and improve compression, making it a simple yet effective way to extend engine life and performance.
