What should be noted when switching from 95 to 92 gasoline?

[VonMichael]

Precautions for switching from 95 to 92 gasoline: Pay attention to whether the vehicle can use 92 gasoline. If the recommended fuel is 92 or higher unleaded gasoline, then decide based on the engine's compression ratio. If the compression ratio is below 11, 92 gasoline can be used. If the compression ratio is above 11, it is better to use 95 gasoline. The octane number of gasoline only represents a parameter of its anti-knock performance. A higher octane number indicates better anti-knock performance and has no relation to purity. The anti-knock performance of gasoline is related to engine operation. Generally, the compression ratio of household car engines is relatively low, making 92 gasoline with lower anti-knock performance suitable.
