Visit Robbins Nissan to learn if you can drive a vehicle without a gas cap.
The first symptom of bad gas cap is probably going to be a gas cap that won't completely tighten or a gas cap that is loose. This may seem insignificant initially, but without an air-tight seal, the entire fuel system can be contaminated with dirt and grime. If the gas cap isn't sealing properly, check the seal to make sure it isn't brittle or missing. If you own an old vehicle, make sure the metal gas cap is not damaged or bent. Both can lead to the gas cap issues and might even require purchasing a replacement from the manufacturer.
These days you might see no gas cap on new cars, but if your car wasn't constructed with a capless gas tank, it is not recommended that you drive without a gas cap installed. If your vehicle is a little older, there's a possibility that gasoline could escape from the fuel tank during hard corners or other enthusiastic driving. Driving without a gas cap could also lead to poor gas mileage because the fuel might evaporate without a fully-sealed tank. The smell is the fuel evaporating from your tank, which causes poor gas mileage.
What problems can a loose gas cap cause? How about a check engine light? A loose gas cap will not only let fuel vapors escape the fuel tank, but it can also let in dirt and grime. These vapors can produce errors in the emissions system, which could light up the check engine light. Dirt and Grime that gets into the fuel tank can also damage the fuel injectors over time. Perhaps the most common sign of a faulty gas cap is the gasoline smell in your car.
If you have already looked at the gas cap, the problems you're having may be caused by bad fuel. If the car has trouble starting, will not accelerate, or just isn't running smoothly, then you might just have a contaminated tank of gas. If your vehicle does not feel right and you are not sure if it's bad fuel or a bad gas cap, bring it on in, and our knowledgeable service technicians will diagnose the issue and give you options for fixing the problem.
