What are the effects of poor fuel quality on a car?

The effects of poor fuel quality on a car include: 1. Using low-quality gasoline not only reduces the car's power output but also causes noticeable vibrations and unusual noises during idling. 2. Secondly, inferior gasoline often lacks good anti-knock properties, making the engine prone to knocking. Over time, this can lead to significant carbon buildup, increasing fuel consumption. 3. In severe cases, it can also damage the catalytic converter, resulting in high repair costs. Remedies for using poor-quality gasoline: 1. If only a small amount of poor-quality gasoline has been added (less than 50% of the tank's capacity), refueling with 97-octane gasoline can help mitigate the effects, usually without causing noticeable issues. 2. However, if a large amount of poor-quality fuel has been added, it is necessary to completely drain the remaining gasoline from the tank and refill it with higher-quality fuel. 3. Additionally, the fuel injectors, combustion chamber, fuel filter, and fuel pump should be cleaned or replaced to prevent clogging from excessive impurities.
I've been driving for almost ten years, and I deeply regret the few times I filled up with substandard fuel. That terrible fuel wreaked havoc on the entire fuel system, causing the engine to cough and struggle for breath frequently. Not only did fuel consumption skyrocket, but the car also shook like a tractor when driving. The scariest part was the difficulty in cold starts due to clogged injectors from gum deposits, and thick carbon buildup formed around the piston rings. When the mechanic opened up the engine, they said continuing like this would lead to cylinder block failure. Later, just cleaning the fuel system cost me nearly two thousand yuan. I sincerely advise everyone not to skimp on fuel—the small savings aren't worth the hefty repair costs down the line.
