How to Test the Quality of Gasoline?
2 Answers
Methods to test the quality of gasoline are: 1. Observe the color of the gasoline; 2. Smell the gasoline; 3. Judge by touch. Gasoline has a high octane rating, and it is classified according to the octane rating into: 89, 90, 92, 93, 95, 97, and 98. The higher the octane number, the stronger the anti-knock performance of the gasoline. Gasoline is a volatile, flammable hydrocarbon mixture liquid obtained from petroleum through distillation, cracking, or pyrolysis, and it can be used as fuel. Sulfur compounds in gasoline can cause corrosion to objects, and it has the ability to resist detonation combustion under various usage conditions.
Color and smell are the most intuitive indicators! I usually pay attention to the color of gasoline when refueling—it should be transparent with a slight yellow tint, like mineral water. If the color is dark or cloudy, it’s likely stale from prolonged storage. When I unscrew the fuel cap and take a sniff, authentic gasoline should have a clean chemical odor. If it smells sour or like pungent paint, there’s definitely a problem. Monitoring fuel consumption after refueling is also crucial—a sudden increase may indicate water contamination or excessive impurities. Residue around the fuel tank opening is another red flag. I once encountered sticky, glue-like substances on the inside of the fuel cap, and the repair shop said such fuel contains too many impurities, which can clog the fuel injectors.
