Can different brands of gasoline be mixed?

[ORhett]

Gasoline from different gas stations and brands can be mixed as long as they have the same octane rating. If the octane ratings are different, even if they are from the same brand, they should not be mixed. Mixing different octane fuels can lead to abnormal combustion, causing engine knocking. Besides damaging the combustion chamber, knocking can directly affect the normal operation of the engine and may even cause severe engine damage. To find out the appropriate octane rating for your car, you can refer to the vehicle's user manual or check the fuel cap for the recommended fuel grade. What to do if the wrong gasoline is added: If a higher octane gasoline than specified is added (e.g., adding 95 octane when 92 is recommended), simply consume the fuel normally and then refill with the correct 92 octane gasoline. If a lower octane gasoline than specified is added (e.g., adding 92 octane when 95 is recommended), you can add a high anti-knock fuel additive. Alternatively, you can drain the fuel and refill with the correct 95 octane gasoline.
