Liqui Moly Engine Flush Plus is an advanced internal engine cleaner formulated to remove sludge, varnish, and built-up contaminants before an oil change. Its powerful blend of detergents and dispersants breaks down both oil-soluble and oil-insoluble residues, suspending them safely so they can be drained out with the old oil. By restoring internal cleanliness, this flush allows your fresh oil to work at full efficiency — improving lubrication, reducing wear, and helping the engine deliver optimal performance. Safe for petrol and diesel engines, as well as vehicles equipped with turbochargers, catalytic converters, and diesel particulate filters (DPF).
