Car dashboard fuel tank symbols include E and F, where E represents an empty tank and F indicates a full tank. Below is a brief introduction to gasoline: 1. Basic information: Gasoline is a volatile, flammable hydrocarbon mixture liquid distilled and cracked from petroleum, used as fuel. It appears as a transparent liquid, is flammable, and has a distillation range of 30°C to 220°C. 2. Composition: Mainly consists of C5~C12 aliphatic hydrocarbons and cycloalkanes, along with a certain amount of aromatic hydrocarbons. Gasoline has a high octane number (anti-knock combustion performance) and is classified into grades such as 89, 90, 92, 93, 95, 97, and 98 based on octane levels. Starting from January 2012, gasoline grades 90, 93, and 97 were revised to 89, 92, and 95.
