Fuel can typically be stored in a gas can for about 3 to 6 months for gasoline, depending on the type and storage conditions. Ethanol-blended gasoline, such as E10, tends to have a shorter shelf life, closer to 3 months, due to its tendency to absorb moisture from the air, which can lead to phase separation and degradation. Pure gasoline, without ethanol, can last up to 6 months. Diesel fuel, on the other hand, can be stored for 6 to 12 months under optimal conditions. However, it is more prone to contamination from water and microbial growth, which can shorten its shelf life. To maximize the storage life of fuel, it should be kept in a tightly sealed, approved container, stored in a cool, dry place away from direct sunlight and temperature fluctuations. Exposure to heat, air, and moisture accelerates the degradation process, leading to the formation of gum and varnish, which can clog fuel systems. Using a fuel stabilizer can extend the shelf life of gasoline by up to 12 months. These additives work by preventing oxidation and the formation of deposits. It's important to add the stabilizer to fresh fuel and ensure it is mixed thoroughly. Regularly checking stored fuel for signs of degradation, such as a sour smell or discoloration, is crucial. If fuel shows signs of spoilage, it should be disposed of properly, as using degraded fuel can damage engines and fuel systems.
