How Long Does Gasoline Last in the Fuel Tank?
1 Answers
Gasoline can last for about 3 months when stored in a sealed fuel tank at room temperature, but this duration may vary depending on storage conditions and the type of gasoline. Below is a detailed explanation of the shelf life of gasoline in a fuel tank: 1. The effective components of gasoline are its light fractions, which are highly volatile. Gasoline stored for too long will have reduced combustible parts, leading to weakened engine performance. 2. The concentration of heavy gum-like substances increases. Using such gasoline can cause clogged fuel injectors, rapid carbon buildup in the engine, and other hazards. 3. Certain types of gasoline, such as ethanol-blended fuel, may develop sediment if stored in the tank for too long, leading to excessive impurities in the fuel pump and potential clogging or damage. It is not recommended to use such gasoline if stored for more than a month. 4. The shelf life of gasoline primarily depends on its oxidation stability. Taking certain measures can improve this stability. Reducing exposure to air, avoiding direct sunlight, and lowering storage temperatures can prevent or slow down oxidation, thereby extending the shelf life of gasoline.
