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 car models and is used for engine maintenance to maintain long-lasting power. To use, add the anti-wear agent to the oil after idling for 10 minutes, then run the engine for 10 minutes or drive normally.
