What to Do If 92 and 95 Gasoline Are Mixed?

[EvaDella]

Here are the solutions for adding the wrong gasoline: If the gasoline added has a higher octane rating than the car requires, for example, adding 95 when 92 is specified, you can simply consume it normally and then switch back to 92 gasoline afterward. If the gasoline added has a lower octane rating than required, such as adding 92 when 95 is specified, you only need to add a high anti-knock fuel additive. Of course, you can also directly drain the fuel and refill with 95 gasoline. To find out which gasoline your car requires, you can check the car's user manual or the fuel cap for the specified octane rating. 92 and 95 gasoline should not be mixed because they have different iso-octane contents. 92 gasoline is suitable for low-compression engines, while 95 gasoline is suitable for high-compression engines. If 92 gasoline is added to a car that requires 95, it may cause abnormal combustion, leading to knocking. Knocking not only damages the combustion chamber but also directly affects the engine's normal operation, potentially causing severe engine damage. Conversely, adding 95 gasoline to a car that requires 92 will not damage the engine, but 95 gasoline is more expensive, leading to unnecessary waste. Differences between 92, 95, and 98 gasoline: Standard gasoline consists of iso-octane and n-heptane. Iso-octane has good anti-knock properties, with an octane rating of 100, while n-heptane has poor anti-knock properties and is prone to knocking in gasoline engines, with an octane rating of 0. If gasoline is labeled 92, it means it has the same anti-knock properties as standard gasoline containing 92% iso-octane and 8% n-heptane. The same principle applies to 95 and 98 gasoline.
