What Happens When Gasoline Quality is Poor?
2 Answers
Poor gasoline quality can lead to increased carbon deposits in the combustion chamber, cause knocking combustion, and result in reduced power and elevated temperatures. Below are the effects of gasoline quality on vehicles and the manifestations of fuel quality. Impact of gasoline quality on vehicles: Gasoline is the heart of a car, and whether its quality meets the national standards for automotive gasoline has a significant impact on the vehicle. Poor fuel quality can 'poison' the car, with minor effects like reduced acceleration and severe cases causing engine damage that requires disassembly for repair. Abnormal car malfunctions are often caused by the use of substandard gasoline. Manifestations of fuel quality: Standard fuel appears colorless, transparent, or golden yellow, while substandard fuel looks cloudy, dark, dull, and may contain suspended impurities. Qualified fuel has a faint, pleasant smell; substandard fuel, if diluted with water, may have a weak odor or extreme pungent and sour smells, leading to exhaust emissions with abnormal odors. Standard gasoline feels cool when dripped on the hand, while slow evaporation or residue indicates poor quality. Cars using substandard fuel may produce noticeable abnormal noises during driving, accompanied by vibrations. Shaking gasoline will produce bubbles; the faster the bubbles disappear, the better the fuel quality.
I've been driving for several years and once encountered a situation where I filled up with poor-quality gasoline. The feeling was truly awful. The engine acceleration became sluggish, it had no power when going uphill, and it occasionally made a rattling noise, as if small parts were fighting inside. The fuel consumption suddenly increased, burning at least one more liter per 100 kilometers. Not only did it cost more, but later, a lot of carbon deposits built up in the engine, and I spent over a thousand on cleaning during maintenance. Now, I always choose reputable gas stations and make sure the fuel tank cap is free of dust to keep the engine running smoothly. If not addressed in time, it could damage the entire fuel system, leading to even higher repair costs. So, I advise everyone not to save money by using bad fuel—what you save now, you’ll pay for later.
