How to Determine the Quality of Gasoline?

[VonTyler]

Methods to determine the quality of gasoline are: 1. Smell it: A strong, pungent gasoline odor indicates poor quality; 2. Observe it visually: Qualified gasoline should be clear, with no floating matter on the surface, no suspended particles in the middle, no sediment at the bottom, and no signs of layering or cloudiness; 3. Touch it: Dip your finger in the gasoline and rub it between your fingers—the stronger the oily feel, the poorer the gasoline quality. Gasoline is a volatile, flammable liquid hydrocarbon mixture obtained from petroleum through distillation, cracking, or pyrolysis, and is used as fuel. It can be classified by octane rating into: 89, 90, 92, 93, 95, 97, and 98. The higher the octane number, the stronger the gasoline's anti-knock performance.
