Liqui-Moly MOS2 Anti-Friction Engine Treatment forms a high load-bearing film on all wearing components which significantly reduces friction, heat and wear. MOS2 (Molybdenum Disulfide) is renowned for its very low co-efficient of friction and ability to “cling” to surfaces even under extreme conditions. Suitable for all petrol, diesel and LP gas engines, safe and effective for all turbocharged and supercharged engines. Can be used in new cars from first oil change, and is effective for the entire period the treated oil is being used in the engine.
