Volkswagen of Alamo Heights welcomes you to find out more about bad gas cap signals.
The most common symptom of faulty gas caps is likely going to be a gas cap that is loose or a gas cap that won’t tighten completely. This might not seem important right away, but if it’s not completely sealed then the entire fuel system can be contaminated with grime and dirt. If the gas cap is not fitting properly, try checking the rubber seal to be sure it isn’t brittle or missing. If you own an old car or truck, make sure the metal gas cap isn’t bent or damaged. Both a bad seal or bent gas cap can cause gas cap issues and might require buying a replacement from the manufacturer.
What problems can a loose gas cap cause, well a check engine light? An ill-fitting gas cap will not only let in dirt and grime, but it can also allow fuel vapors to escape the fuel tank. These vapors could cause an error in the emissions system, which would light up the check engine light. Dirt that seeps into the fuel tank may also damage injectors over time. Perhaps the most common sign of a faulty gas cap is the smell of gasoline inside your vehicle.
These days you might see no gas cap on new cars, but if your car, truck, or SUV was not made with a capless gas tank, it’s not recommended that you drive without a gas cap. If your car is a little older, there is a chance that gasoline could leak out from the gas tank during hard cornering or other spirited driving. If you drive your car without a gas cap, it can lead to poor gas mileage because the gasoline may evaporate without the correct seal on the fuel filler. The smell is the gas evaporating from the gas tank, which causes reduced fuel efficiency.
If you’ve checked out the gas cap, the problems you are having may be due to contaminated gasoline. If your vehicle has problems starting, won’t accelerate, or just is not running smoothly, then it’s entirely possible you just have a bad tank of gas.
