How Many Months Must a Full Tank of Gasoline Be Used Up Within at Most?

[DelRuth]

A full tank of gasoline must be used up within three months at most. Here are the specific details: 1. Time: The shelf life of gasoline in a car's fuel tank is three months. 2. Reason: Due to gasoline's lower density compared to diesel, lower ignition point than diesel, and higher volatility than diesel, its shelf life is shorter than that of diesel. Here is some additional information: 1. Introduction and Function: Gasoline is a volatile, flammable hydrocarbon mixture liquid distilled and cracked from petroleum, used as fuel. 2. Main Components: The main components are C5 to C12 aliphatic hydrocarbons and cycloalkanes, along with a certain amount of aromatic hydrocarbons. 3. Classification: Gasoline has a high octane number (anti-knock combustion performance) and is classified by octane ratings such as 89, 90, 92, 93, 95, 97, and 98. Starting from January 2012, the gasoline grades 90, 93, and 97 were revised to 89, 92, and 95.
