BMW of Tulsa welcomes you to find out more about bad gas cap signs.
The most common symptom of faulty gas caps is likely going to be a gas cap that is loose or a gas cap that will not completely tighten. This may not seem significant right away, but without an air-tight seal, the entire fuel system can be exposed to dirt and grime. If the gas cap is not fitting properly, try checking the seal to make sure it’s not brittle or missing. If you own an old vehicle, make sure the metal gas cap is not damaged or bent. Both a bad seal or bent gas cap can cause gas cap issues and may require a replacement from the original manufacturer.
What issues can an ill-fitting gas cap cause, well a check engine light for starters? A loose gas cap will not only let in grime and dirt, but it can allow fuel vapors to escape. These fuel vapors can produce an error in the emissions system, which could cause the check engine light to turn on. Dirt that gets into the fuel tank could also contaminate fuel injectors over time. Perhaps the biggest sign of a faulty gas cap is the gasoline smell in your vehicle.
These days you might see no gas cap on new cars, but if your vehicle wasn’t built with a capless gas tank, it is not recommended that you drive without a gas cap installed. If your car is older, there’s a possibility that gas could slosh out from the fuel tank during aggressive cornering or enthusiastic driving. If you drive without a gas cap, it can lead to poor fuel efficiency because the gas could potentially evaporate without a fully-sealed fuel filler. The smell is the fuel evaporating from your tank, which can cause poor gas mileage.
If you’ve already inspected the gas cap, the problems you are having may be caused by contaminated fuel. If your vehicle has trouble starting, will not accelerate, or just is not running right, then you might just have a bad tank of gas.
