How to Distinguish the Quality of Gasoline?
2 Answers
Gasoline quality can be distinguished by its color and smell. Here is an introduction to gasoline: 1. Definition: It is a volatile, flammable hydrocarbon mixture liquid obtained from petroleum through distillation, cracking, or pyrolysis, primarily used as fuel for spark-ignited internal combustion engines. 2. Categories: It mainly includes organic compounds derived from crude oil distillation and various additives. 3. Function: Based on different octane ratings, gasoline can be classified into several grades. Other chemicals are often added to gasoline to improve chemical stability and other properties, control corrosiveness, and maintain fuel system cleanliness.
The key to distinguishing between good and bad gasoline lies in daily driving experience. After years of driving, I've found that high-quality gasoline makes the engine run smoothly, with quick starts, strong acceleration, and responsive throttle. Poor-quality gasoline immediately shows problems, such as engine knocking, a sudden increase in fuel consumption by several liters, or even difficulty starting. The most noticeable signs are the engine sound and exhaust emissions—good gasoline burns completely, with no smoke or strange odors, while low-quality gasoline produces black smoke or pungent smells and may cause significant vibrations. I recommend choosing reputable gas stations like Sinopec or Shell, which have stable fuel sources and more additives. In hot weather, gasoline evaporates faster, so freshness is crucial—avoid cheap, old stock from small stations, as it can damage components and increase repair costs. Safe driving comes first; if you suspect fuel issues, stop immediately to check and prevent accidents.
