Using your DC Sport oil cap is a piece of cake. Just remove the old oil cap from your Honda, Nissan, or Suzuki engine and screw on the new one tightly. Make sure it's properly seated to get the best seal. When it comes to maintenance, keep an eye on the O-ring. If it looks worn out or damaged, it's a good idea to replace it. You can clean the cap with a mild soap and water solution and dry it thoroughly. Avoid using harsh chemicals as they might damage the anodized finish. And remember, don't overtighten the cap when installing it, as this could cause damage to the engine threads.
