Cedar Park Nissan invites you to understand what the signs of a malfunctioning gas cap are.
The most common symptom of faulty gas caps is probably a loose gas cap or a gas cap that won’t tighten completely. This may seem insignificant at first, but without an air-tight seal, the entire fuel system can be exposed to dirt and grime. If your gas cap is not closing properly, try checking the rubber seal to be sure it isn’t brittle or missing. If you have an older vehicle, 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 may even require buying a replacement from the original manufacturer.
What issues can a loose gas cap cause, well a check engine light? A loose gas cap will not only let fuel vapors escape the fuel tank, but it can also let in grime and dirt. These vapors could cause an error in the emissions system, which would cause the check engine light to come on. Dirt that gets into the fuel tank can also damage injectors over time. The biggest indicator of a faulty gas cap is the gasoline smell in your car.
These days you might see no gas cap on new cars, but if your car was not constructed with a capless fuel tank, it’s not recommended that you drive without a gas cap installed. If your vehicle is older, there is a chance that fuel could escape from the fuel tank during aggressive corners or other spirited driving. If you drive without a gas cap, it can lead to diminished gas mileage because the gasoline might evaporate without a fully-sealed fuel filler. The gas smell is the fuel evaporating from your gas tank, which causes poor fuel efficiency.
If you’ve inspected the gas cap, the problems you are having may be caused by contaminated fuel. If a vehicle has trouble starting, won’t accelerate, or just is not running correctly, then you might just have bad gas.
