Our engine anti-wear protector is carefully prepared from sodium tripolyphosphate and sodium gluconate. Designed to reduce wear and corrosion and delay engine components aging. How to use: 1. After replacing new engine oil, start the engine and keep running at idle for 5 minutes to ensure warm-up, then turn off. 2. Pour the whole can into the oil tank and run at idle for at least 15 minutes for thorough mixing. 3. For 6-cylinder engines, recommend 1 can or 5% of total oil volume. 4. Add every 12,000-15,000 km with new oil for best results. It optimizes friction coefficient, improves engine efficiency and power output.
