Group 1 Chevrolet Northwest invites you to understand more about malfunctioning gas cap signals.
The first symptom of bad gas caps is likely going to be a gas cap that will not completely tighten or a loose gas cap. This might not seem important right away, but if it’s not completely sealed then the fuel system can be contaminated with grime and dirt. If the gas cap is not sealing properly, try checking the seal to be sure it isn’t brittle or missing. If you drive an old car or truck, make sure the metal gas cap isn’t bent or damaged. Both can cause gas cap problems and may even 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 the fuel tank, but it can also let in grime and dirt. These fuel vapors can trigger an error in the emissions system, which would light up the check engine light. Grime that seeps into the fuel tank could also contaminate injectors. The most common sign of a faulty gas cap is the gasoline smell in your car.
If your vehicle wasn’t made with a capless fuel tank, you shouldn’t drive without a gas cap. If your vehicle is a little older, there is a chance that fuel could leak out from the tank during aggressive corners or other spirited driving. If you drive your car without a gas cap, it can lead to diminished fuel efficiency because the gasoline might evaporate without the correct seal on the fuel filler. The gas smell is the fuel evaporating from your gas tank, which can cause reduced fuel economy.
If you’ve checked out the gas cap, the problems you’re having might be caused by contaminated gasoline. If a vehicle has problems starting, won’t accelerate, or just isn’t running correctly, then you might just have contaminated gas.
