Visit Beck & Masten Buick GMC North to learn about the problems a bad gas cap can cause.
The first of many symptoms of bad gas cap is probably going to be a loose gas cap or a gas cap that will not completely tighten. This might seem insignificant at first, but if you don’t have an air-tight seal then the fuel system can be contaminated with dirt and grime. If the gas cap isn’t closing properly, try checking the gasket to make sure it’s not brittle or missing. If you drive an old car, 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 might require buying a replacement from the manufacturer.
These days you could possibly see no gas cap on new cars, but if your vehicle wasn’t built with a capless fuel tank, it is not recommended that you drive without a gas cap. If your vehicle is older, there’s a possibility that gasoline could escape from the fuel tank during aggressive cornering or other spirited driving. If you drive without a gas cap, it can lead to poor fuel economy because the gas could potentially evaporate without the correct seal on the fuel filler. The gas smell is the gas evaporating from the gas tank, which can cause diminished fuel economy.
What problems can an ill-fitting gas cap cause, well a check engine light? A loose gas cap will not only let fuel vapors escape, but it can also let in dirt and grime. These vapors can cause an error in the emissions system, which could light up the check engine light. Grime that gets into the fuel tank can also damage the fuel injectors over time. The most common indicator of a faulty gas cap is the smell of gasoline in your vehicle.
If you’ve inspected the gas cap, the problems you are having might be due to bad gas. If the car, truck, or SUV has difficulty starting, won’t accelerate, or just is not running right, then you might just have contaminated gas.
