Signs of a Bad Gas Cap

signs of a bad gas cap

Mercedes-Benz of Boerne welcomes you to learn what the signs of a bad gas cap are.

The 1st of many symptoms of faulty gas caps is likely going to be a gas cap that won’t completely tighten or a loose gas cap. This may seem insignificant, but if you don’t have an air-tight seal then the entire fuel system can be contaminated with grime and dirt. If your gas cap is not sealing properly, check the rubber gasket to be sure it’s not brittle or missing. If you own an older vehicle, be sure the metal gas cap isn’t damaged or bent. Both can lead to the gas cap issues and might require purchasing a replacement from the original manufacturer.


Gas Cap Check Engine Light, How Does It Happen?

What Causes a Gas Cap Check Engine Light?

What concerns can a non-secure gas cap cause, well a check engine light? An ill-fitting gas cap will not only let fuel vapors escape, but it can also let in grime and dirt. These gasoline vapors could trigger errors in the emissions system, which could cause the check engine light to turn on. Dirt that seeps into the gas tank may also contaminate fuel injectors. The most common indicator of a bad gas cap is the smell of gasoline inside your vehicle.

Can a Bad Gas Cap Cause Stalling?

Can You Drive Without a Gas Cap?

If your car wasn’t constructed with a capless gas tank, you shouldn’t drive without a gas cap installed. If your vehicle is a little older, there is a possibility that fuel could leak out from the fuel tank during hard cornering or other spirited driving. If you drive without a gas cap, it can lead to poor fuel economy because the fuel might evaporate without a fully-sealed gas tank. The gas smell is the gasoline evaporating from the gas tank, which can cause diminished fuel efficiency.
