How to Distinguish Good and Bad Gasoline?

[VonAbigail]

There are several methods to distinguish good and bad gasoline: 1. Smell with your nose: The heavier the gasoline smell, or even irritating, the worse the quality. Poor-quality gasoline has a pungent, eye-stinging, or foul odor, indicating excessive sulfur content. The octane number is an agreed value for evaluating gasoline quality, so generally, gasoline with high sulfur content is not good. When smelling, do not directly sniff the gasoline; instead, gently wave your hand over the container opening to catch the scent. 2. Observe with your eyes: The color of gasoline can indicate its quality. Generally, 93# gasoline appears transparent yellow, and 97# gasoline appears emerald green. Qualified gasoline is usually very clear, with no floating objects on the surface, no suspended particles in the middle, no sediment at the bottom, and no stratification or turbidity. Conversely, if the gasoline appears turbid, stratified, with suspended particles or sediment, it indicates potential quality issues. 3. Touch with your hand: Dip your finger in the gasoline and rub it a few times. If your finger feels very oily, like engine oil, the gasoline quality is poor. Alternatively, pour a little gasoline on your hand; if it evaporates quickly, the gasoline quality is good.
