Can Gasoline Be Used After 5 Years of Storage?

[DePaisley]

Gasoline stored for five years is not recommended for continued use. Gasoline has its own shelf life; opened gasoline in a bottle can last up to 3 months, while sealed gasoline can be stored for a maximum of 2-5 years. Gasoline is primarily used as fuel for spark-ignition internal combustion engines in vehicles. The octane rating of gasoline indicates its octane number—the higher the rating, the higher the octane number. When refueling, it is important to note that different grades of gasoline should not be mixed, as this can lead to engine knocking, which may shorten the lifespan of the vehicle. For storing gasoline, it is best to use metal containers and ensure proper sealing to prevent evaporation and leakage. The container should not be filled to the brim; leave some space to allow for the expansion of volatile gasoline components, avoiding excessive internal pressure that could cause an explosion. Additionally, gasoline containers should be kept away from open flames or high-temperature areas and stored in a cool, well-ventilated warehouse.
