Setup, Compatibility & Care
Before adding K2 Stop Leak, ensure your engine oil level is checked and is not overfilled. One 50ml bottle is designed for approximately 4 litres of engine oil. Simply pour the contents directly into the oil filler port when the engine is warm. Compatibility is broad, covering standard mineral, semi-synthetic, and synthetic oils. Always consult your vehicle manufacturer's handbook to ensure the use of additives is permitted within your specific warranty terms. For best results, add the product during a routine oil change so it can mix thoroughly with fresh oil throughout the service interval.
