Oil Additive for high load or full throttle driving. Substantially reduces wear & extends engine life. Less heat, smooth running, reduced fuel consumption. Perfect for engines used in high load applications like extended towing and full throttle driving conditions. Liqui-Moly MOS2 Friction Reducer forms a high load-bearing film on all wearing components which significantly reduces friction, heat and wear. MOS2 (Molybdenum Disulfide) “clings” to surfaces even under extreme conditions. Suitable for all petrol, diesel and LPG 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.
