Can Gasoline Be Used After Three Years of Storage?
1 Answers
Gasoline cannot be used after three years of storage. The shelf life of gasoline is generally around three months. Gasoline has strong volatility and hygroscopicity, and is easily affected by environmental factors such as temperature and humidity. If stored improperly, gasoline will absorb moisture from the air upon contact, and when it reaches a certain level, it will form a milky-white stratification, leading to deterioration. Gasoline is a volatile and flammable liquid hydrocarbon mixture obtained from petroleum through fractionation, cracking, or pyrolysis. It is used as fuel and appears as a transparent liquid, primarily composed of aliphatic hydrocarbons, naphthenic hydrocarbons, and a certain amount of aromatic hydrocarbons. Gasoline has a high octane rating and is classified into grades such as 89, 90, 92, 93, 95, 97, and 98 based on the octane number.
