What happens if you use 92 octane gasoline when 95 is recommended?

[BeauMarie]

Using 92 octane gasoline once or twice will not cause any harm to the car or the engine, but prolonged use may lead to engine knocking. Here is an introduction to gasoline: 1. Changing gasoline grades: If you want to switch gasoline grades, you can do so directly; 2. Refuel when the fuel gauge light is on: When switching from a higher octane gasoline to a lower one, it is best to wait until the fuel in the tank is used up to the point where the fuel gauge light comes on, i.e., when the fuel gauge pointer is in the red zone. Below is additional information on the differences between 92 and 95 octane gasoline: 1. Different anti-knock properties: The octane rating represents the anti-knock properties, with higher numbers indicating better anti-knock capabilities; 2. Different isooctane content: 92 octane gasoline consists of 92% isooctane and 8% n-heptane, while 95 octane gasoline consists of 95% isooctane and 5% n-heptane. The slightly higher price of 95 octane gasoline is due to the higher proportion of isooctane; 3. Price difference: A tank of 95 octane gasoline is slightly more expensive than a tank of 92 octane gasoline.
