Using your DC Sport Anodized Oil Cap is simple. First, make sure your engine is cool. Then, remove the old oil cap and clean the area around the oil filler hole. Place the new DC Sport oil cap on the hole and turn it clockwise until it's snug. That's it! When it comes to maintenance, you don't need to do much. Just wipe the cap with a clean cloth every few months to keep it looking good. And remember, don't overtighten the cap as it can damage the O - ring and lead to leaks. If you notice any signs of wear or if the seal seems to be failing, it's time to replace the cap.
