What to Do If You've Filled Up with Low-Quality Gasoline?
2 Answers
Promptly visit a 4S dealership to completely drain the remaining fuel from the tank, refill with high-quality gasoline, clean the fuel injectors and combustion chamber, and replace the fuel filter. Below is more information about low-quality gasoline: 1. Hazards: It can cause engine carbon deposits, fuel system blockages, reduced vehicle performance, and failure of the oxygen sensor and catalytic converter. 2. Identification Methods: Observe the appearance of the fuel, smell its odor, and test a few drops for volatility. Qualified gasoline evaporates easily, typically completely evaporating within one to two minutes. Slow evaporation or noticeable residue indicates abnormal fuel quality.
When I first bought my car, I foolishly filled up with low-quality fuel to save money—what a regret! The engine noise became noticeably rougher, acceleration felt sluggish, and the dashboard warning light came on. I immediately pulled over, turned off the engine, and called the dealership. They sent a tow truck to haul my car in for inspection. Cleaning the fuel tank cost me 800 RMB, and replacing the fuel filter added another 400-plus. The mechanic warned that impurities in substandard fuel can clog injectors, damage oxygen sensors, and even score cylinder walls in severe cases. Now, I strictly refuel at Sinopec stations—I’d rather drive extra miles than risk sketchy gas. Had I kept driving back then, engine repairs would’ve cost me two years’ worth of fuel!
