Is It a Big Problem to Fill Up with Low-Quality Fuel Once?

[VonHeidi]

In daily driving, if you accidentally fill up with low-quality gasoline once and no warning light appears on the vehicle, it indicates that the car is fine. However, if the vehicle displays a warning light, do not start the engine again and promptly contact a repair shop for maintenance. The hazards of low-quality fuel are as follows: Clogging the fuel system: Low-quality fuel contains more impurities, which can lead to incomplete combustion, producing numerous fuel residues that obstruct the fuel supply, causing severe vehicle shaking during driving. Engine carbon buildup: The incomplete combustion of gasoline generates carbon deposits that adhere to the engine's surface, soon leading to increased fuel consumption and, over time, potential engine damage. Damage to the catalytic converter and oxygen sensor: Substandard fuel quality results in poor exhaust emissions after combustion. The catalytic converter purifies exhaust gases for emission, but if the exhaust contains excessive impurities, they can adhere to the catalytic converter, causing its damage.
