Can Poor Fuel Quality Cause Engine Vibration?

[NoraFitz]

Poor-quality gasoline usually contains a high water content and more impurities. Water is not easy to burn, so the engine may experience poor combustion, leading to engine vibration. Impurities in gasoline can clog the fuel injectors, resulting in poor atomization and generating a large amount of carbon deposits, which can also cause engine vibration. Methods to identify poor fuel quality: 1. If the fuel contains water, it may have a weak gasoline smell and appear overly light in color. 2. Unusual odors that differ from the typical gasoline smell. 3. If the gasoline contains excessive gum, it may appear darker in color, presenting an orange-red hue. 4. Gasoline with too many impurities may look cloudy.
