Tighten that gas cap

This little plastic cap doesn't just hold in liquid fuel after you've gassed up, it keeps vapor from leaking out, too. To ensure that it's on tight enough to maintain fuel economy and prevent the check engine light from coming on, be sure to twist the cap until it clicks. Refer to the owner’s manual of your car to know how many clicks you should hear for proper tightness.
