Fuel Saving Tip from Martin's Auto Center: Gas Cap

Last Updated: Jul 01, 2025

This fuel saving tip for Mount Vernon residents is so simple you won't believe it. It has to do with your gas cap. The first thing is to make sure it's screwed on tight. If it's loose, gas vapor will be constantly leaking out – reduced fuel economy. This could cause the check engine light to come on as well.

A worn gas cap can have the same effect. If you constantly smell gas when you walk by your tank, you might need a new gas cap.

So, twist your cap until it clicks three times – that means it's on tight. Have your friendly and knowledgeable Martin's Auto Center inspect the cap to see if it needs to be replaced. See, I told you it was simple.
