What are the manifestations of poor gasoline quality?
1 Answers
If the quality of gasoline is poor, the most obvious phenomenon is increased carbon deposits in the engine. The increase in carbon deposits may not be visible from the outside. If inferior gasoline is frequently used, a significant amount of black carbon deposits can be observed inside the engine when inspected with an endoscope. Poor gasoline quality can also manifest as difficulty starting or even failure to start; engine shaking at idle after starting; noticeable vibrations in the vehicle body; unpleasant odor from exhaust gases; valve noise; lack of power during acceleration and increased fuel consumption; and gear shifting with jerks. Solutions: Completely drain the remaining fuel in the tank, refill with high-quality gasoline, clean the fuel injectors, clean the combustion chamber, and replace the fuel filter. It is recommended that car owners choose high-quality gasoline and the correct gasoline grade when refueling. Methods to determine gasoline quality: Observe the color: Standard fuel should appear golden yellow or colorless and transparent. Fuel that is cloudy, black, dull, or contains suspended particles may be of inferior quality. Smell the odor: Inferior fuel typically exhibits two extreme types of odor. One is diluted gasoline with a very faint gasoline smell, and the other has a strong, foul, pungent, or sour odor. The exhaust emissions will also have an unusual smell. Qualified fuel has a faint aromatic odor. Test by touch: Qualified gasoline is highly volatile. Dip your fingers in a few drops of gasoline. If the gasoline is qualified, your fingers will feel cool. Slow evaporation or noticeable residue indicates poor fuel quality. Listen for sounds: Generally, vehicles using inferior fuel will produce noticeable abnormal noises during driving, accompanied by shaking. Shake it: Shaking gasoline will produce bubbles. The faster the bubbles disappear, the better the fuel quality.
