What are the symptoms of poor fuel quality?
1 Answers
Symptoms of poor fuel quality are as follows: 1. Smell test: The heavier the gasoline smell, or even pungent gasoline, the poorer the fuel quality. Inferior gasoline has irritating odors such as pungent, eye-burning, and foul smells. This indicates that the gasoline has an excessively high sulfur content. The octane number is an agreed value for evaluating gasoline quality, so generally, gasoline with excessively high sulfur content is not good. When smelling, do not directly sniff the fuel with your nose; instead, gently wave your hand over the container opening to detect the odor. 2. Visual inspection: The quality of gasoline can be judged by its color. Generally, 93# gasoline appears transparent yellow, and 97# gasoline appears emerald green. Qualified fuel is usually very clear, with no floating substances on the surface, no suspended particles in the middle, no sediment at the bottom, and no layering or turbidity. Conversely, if the fuel appears turbid, layered, has suspended particles, or sediment, it indicates potential quality issues. 3. Touch test: Dip your finger into the fuel and rub it a few times. If your finger feels greasy, similar to engine oil, then the quality of this gasoline is poor. Alternatively, pour a little gasoline onto your hand. If it evaporates quickly, the quality of this gasoline is good.
