Gasoline, the fuel that powers most vehicles, has a limited shelf life. Over time, it can degrade and become less effective, leading to a variety of performance issues in your car.
How Long Does Gasoline Last? The shelf life of gasoline depends on several factors, including the type of gasoline, the storage conditions, and the presence of additives. Typically, gasoline stored in a sealed container in a cool, dark place can last up to six months. However, if the gasoline is exposed to air or heat, its shelf life can be significantly reduced.
