How to Test the Quality of Gasoline?

[LeJayce]

Methods to test the quality of gasoline are: 1. Observe the color of gasoline: Normally, gasoline should be water-white in color. If the color darkens, it may indicate that the gasoline has been stored for too long; 2. Usage observation: Check if fuel consumption has increased and inspect the exhaust pipe for sticky substances, as their presence suggests poor-quality gasoline; 3. Smell test: Gently waft the gasoline's odor. If there is a pungent smell, such as spiciness, eye irritation, or unusual odors, it means the gasoline contains excessive sulfur and likely other impurities; 4. Touch test: Rub a small amount of gasoline between your fingers. If the greasy sensation is strong, similar to engine oil, it indicates the gasoline quality is not good.
