Can CNOOC and Sinopec Gasoline Be Mixed?

[LeOlive]

Gasoline from different gas stations and brands can be mixed as long as they have the same octane rating. If the octane ratings differ, even if the gasoline is from the same brand, it should not be mixed. Mixing different octane ratings can lead to abnormal combustion, causing engine knocking. Knocking not only damages the combustion chamber but also directly affects the engine's normal operation, potentially leading to severe engine damage. To determine the appropriate gasoline grade for your vehicle, refer to the car's user manual or check the fuel grade indicated on the fuel tank cap. Handling incorrect gasoline usage: If you use gasoline with a higher octane rating than required (e.g., using 95 octane when 92 is specified), simply switch back to 92 octane after consuming the current fuel. If you use gasoline with a lower octane rating than required (e.g., using 92 octane when 95 is specified), you can add a high anti-knock fuel additive. Alternatively, you can drain the incorrect fuel and refill with the specified 95 octane gasoline.
