Using this DC Sport anodized oil cap is a piece of cake. Just align it with the oil filler opening and gently turn it clockwise until it's firmly in place. When you need to remove it for an oil change or inspection, turn it counter - clockwise. As for maintenance, keep it clean by wiping it with a soft, dry cloth. Avoid using harsh chemicals that could damage the anodized finish. Also, regularly check the O - ring for any signs of wear or damage. If it looks worn out, replace it to ensure a proper seal. And remember, this cap is specifically designed for Hyundai vehicles, so don't try to use it on other models.
