Can gasoline still be used after being stored for a long time?

[DelMackenzie]

Gasoline cannot be used after being stored for a long time. Prolonged storage of gasoline leads to severe oxidation, forming gum. This gum can cause valves to stick, resulting in poor sealing. At high temperatures, it decomposes into carbon deposits that accumulate in fuel lines and other components, leading to poor engine performance. Additionally, due to gasoline's volatile nature, its octane rating decreases during evaporation, resulting in less gasoline and reduced effectiveness. Gasoline is a volatile, flammable hydrocarbon mixture liquid derived from petroleum through distillation, cracking, or pyrolysis. It is used as fuel and appears as a transparent liquid, primarily composed of aliphatic hydrocarbons, naphthenes, and a certain amount of aromatic hydrocarbons.
