Engine Anti Wear Protector is a single molecule petroleum compound that penetrates the metal surface of the engine, forming a protective film and reducing friction induced 'cold start' damage to the vehicle. It is suitable for diesel and gasoline universal cars and is used for engine maintenance to maintain long-lasting power. The product comes in a 100ml bottle and has a net weight of approximately 100g. To use, simply add the anti-wear agent to the oil after idling for 10 minutes, then run the engine for 10 minutes or drive normally.
