Using this oil filler cap is easy. Just remove your old cap and screw this one on tightly. Make sure it's well - seated to prevent any oil leaks. When you're doing regular maintenance on your vehicle, check the cap's tightness. If it seems loose, tighten it up. To keep it looking great, clean it with a mild soap and water solution. Avoid using harsh chemicals as they might damage the red finish. Also, if you notice any signs of wear or damage, it's a good idea to replace the cap to ensure the best performance for your engine.
