Liqui Moly Pro-Line Engine Flush – 500ml

Keep your diesel engine running smoothly and efficiently with Liqui Moly Pro-Line Engine Flush Diesel, a high-performance solution designed to clean and protect your engine from the inside out. Over time, harmful deposits like sludge, varnish, and carbon build up inside your engine due to combustion and oil breakdown. These contaminants reduce efficiency, cause rough idling, and lead to premature engine wear. This is where Liqui Moly’s trusted German engineering steps in.

Liqui Moly Pro-Line Engine Flush is a specially formulated additive that is poured directly into the engine oil before an oil change. It circulates through the engine during idling, gently loosening and dissolving contaminants without damaging engine seals or components. Within just 10–15 minutes, this flush thoroughly cleans oil circuits, pistons, valves, and hydraulic components.

Ideal for diesel engines of all types—passenger vehicles, SUVs, light commercial vehicles—this product helps restore original engine performance, reduce fuel consumption, and extend the life of your engine and new oil. After flushing, simply drain the old oil and replace it with fresh oil and a new filter for best results.

The formula is free from aggressive solvents and safe for use with all diesel engine types, including turbocharged and common rail systems. Using Liqui Moly Pro-Line Engine Flush regularly—especially in high-mileage or older vehicles—ensures smoother operation, improved lubrication, and fewer engine problems down the road.

Whether you’re a DIY car enthusiast or a professional mechanic, this engine flush is an essential maintenance step for keeping diesel engines in optimal condition. Trusted by workshops worldwide, it’s a small step that makes a big difference in engine health.
