Indicators of Bad Gas

Group 1 Ford of El Paso welcomes you to learn what the indicators of bad gas are.

The first symptom of faulty gas caps is a loose gas cap or a gas cap that won’t tighten completely. This may seem insignificant at first, but if it’s not fully sealed then the fuel system can be contaminated with dirt and grime. If your gas cap isn’t sealing properly, check the rubber gasket to make sure it isn’t brittle or missing. If you drive an old car or truck, be sure the metal gas cap isn’t damaged or bent. Both a bad seal or bent gas cap can cause gas cap issues and might require a replacement from the manufacturer.

What concerns can a non-secure gas cap cause? How about a check engine light? A loose gas cap will not only let fuel vapors escape, but it can also let in dirt and grime. These gasoline vapors can cause an error in the emissions system, which could cause the check engine light to come on. Dirt and Grime that gets into the gas tank may also damage injectors. Perhaps the most common sign of a faulty gas cap is the smell of gasoline in your car.

How Far Should You Drive Without a Gas Cap?

These days you may see no gas cap on new cars, but if your vehicle was not built with a capless fuel tank, you shouldn’t drive without a gas cap. If your vehicle is a little older, there’s a possibility that fuel could slosh out from the fuel tank during hard cornering or other spirited driving. Driving without a gas cap could lead to diminished gas mileage because the fuel may evaporate without a fully-sealed tank. The gas smell is the gasoline evaporating from the fuel tank, which causes diminished gas mileage.
