What is the difference between using 92 and 95 gasoline in cars?

[KiaraAnn]

Here is a detailed introduction to the differences between 92 and 95 gasoline: Composition: 92 gasoline contains 92% isooctane and 8% n-heptane, while 95 gasoline contains 95% isooctane and 5% n-heptane. Anti-knock performance: 95 gasoline has better anti-knock performance than 92 gasoline. The octane rating of 92 and 95 gasoline represents the fuel's anti-knock performance; the higher the rating, the higher the isooctane content, indicating better anti-knock performance. Compression ratio: 95 gasoline is better suited for engines with higher compression ratios than 92 gasoline. Engines with a compression ratio greater than 9:1 should use gasoline with an octane rating of 90 or higher; engines with a compression ratio greater than 9.5:1 should use 92 or higher; and engines with a compression ratio greater than 10:1 should use 95 or higher octane gasoline.
