What Problems Can A Loose Gas Cap Cause?

what problems can a loose gas cap cause?

Visit Beck & Masten Buick GMC Coastal Bend to learn about the problems a loose gas cap can cause.

The 1st symptom of bad gas cap is probably a gas cap that is loose or a gas cap that won’t completely tighten. This may not seem important right away, but if it’s not completely sealed then the fuel system can be exposed to grime and dirt. If your gas cap is not closing properly, try checking the gasket to be sure it isn’t missing or brittle. If you drive an old car, be sure the metal gas cap isn’t damaged or bent. Both can cause gas cap issues and might require buying a replacement from the original manufacturer.


No Gas Cap on New Cars?

Can a Bad Gas Cap Cause Stalling?

If your car wasn’t made with a capless gas tank, it is not recommended that you drive without a gas cap. If your car or truck is a little older, there is a chance that gasoline could slosh out from the tank during aggressive corners or spirited driving. Driving without a gas cap can lead to poor fuel efficiency because the fuel could evaporate without the correct seal on the fuel filler. The gasoline smell is the gas evaporating from your tank, causing poor gas mileage.

Gas Cap Check Engine Light, How Does It Happen?

What concerns can a non-secure gas cap cause? How about a check engine light? A non-secure gas cap will not only let fuel vapors escape the gas tank, but it can also let in grime and dirt. These fuel vapors may trigger errors in the emissions system, which would light up the check engine light. Dirt and Grime that gets into the fuel tank could also contaminate fuel injectors. The most common indicator of a bad gas cap is the gasoline smell inside your car.
