What to Do If the Wrong Gasoline Grade is Added to the Car?

If the wrong gasoline grade is added to the car, do not start the engine. The car should be towed to a repair shop for a thorough cleaning of the fuel tank to prevent engine knocking. Here is more information about car gasoline grades: 1. Oil grades represent different categories of engine oil. Numbers like 20, 30, 40, 50 indicate the viscosity of the oil, with higher numbers representing thicker oil, suitable for use in high-temperature areas. The 'W' in 0W, 5W, 10W, 15W, 20W, 25W stands for Winter, and the smaller the number before 'W', the better the low-temperature viscosity. 2. Different gasoline grades correspond to different requirements for the car's compression ratio. The higher the engine compression ratio, the higher the required gasoline grade. Generally, engines with a compression ratio above 8.0 should use 92-octane gasoline; those above 9.0 should use 95-octane gasoline; and those above 10.0 should use 98-octane gasoline.
Last time I filled up with the wrong fuel grade - 90 octane instead of the required 95 octane, which threw me into a panic. The key was not to start the engine at all, as it could cause knocking and damage. I immediately called a tow truck to take the car to a repair shop for fuel system cleaning, spending over 500 yuan to save my vehicle. After this incident, I learned my lesson: always double-check the fuel pump grade before refueling. I now use reminder apps on my phone or stick labels on the fuel cap as preventive measures. In the long run, regular engine maintenance also helps reduce risks - it's money well spent. Never take chances; proper handling prevents bigger troubles.
