Our engine protectant contains viscosity improvers and anti-friction additives. It can minimize the noise and vibration of the engine to the greatest extent. Its usage method is very simple: turn off the engine and wait for it to cool down. Check the engine oil level. Open the fuel tank cap， pour in an appropriate amount of anti-wear protective agent， and tighten the filling cap. Start the engine and run it at the total speed for a few minutes to fully mix the protective agent and engine oil. Drive a short distance to ensure the normal operation of the engine. And it can form a protective layer on the engine components， significantly reducing wear， extending the engine's lifespan， while keeping the engine running at peak performance， reducing friction and making operation smoother.
