Our engine anti-wear protective agent is carefully formulated from mineral oil anti-wear additives and antioxidants. Designed specifically to form a protective barrier on important engine components reducing friction during operation and minimizing wear. The usage method is extremely convenient: 1. Turn off the engine and wait for it to cool down. Check the engine oil level. 2. Open the oil filler cap pour in an appropriate amount of engine booster and maintenance agent and then tighten the filler cap. 3. Start the engine and let it idle for a few minutes to ensure that the protective agent and the engine oil are thoroughly mixed. 4. Drive a short distance to ensure the engine is running normally. Moreover this anti-wear agent has a high viscosity and good adsorption capacity which can protect gears and prevent wear.
