What are the consequences of filling a car that requires 95 octane with 92 octane fuel?

[LeCharles]

The consequences of filling a car that requires 95 octane with 92 octane fuel include reduced power, engine shaking, and knocking. The principles for selecting gasoline octane ratings and the differences between 92 and 95 octane gasoline are as follows: Principles for selecting gasoline octane ratings: The compression ratio of the engine is the sole criterion for choosing the gasoline octane rating. Generally, engines with a compression ratio of 10:1 or higher should use 95 octane or higher gasoline. Car owners can refer to the manual or the label near the fuel tank cap to select the appropriate gasoline. Differences between 92 and 95 octane gasoline: The difference between 92 and 95 octane gasoline lies not in quality but in the content of added isooctane, which affects the gasoline's anti-knock properties. 95 octane gasoline contains a higher proportion of isooctane, making it slightly more expensive and providing better anti-knock performance.
