What are the octane ratings of 92 and 95 gasoline?

[VanZoey]

92 gasoline contains 92% isooctane and 8% n-heptane, while 95 gasoline contains 95% isooctane and 5% n-heptane. Relevant information about gasoline grades is as follows: 1. The gasoline grade represents the fuel's anti-knock performance. The higher the grade, the better the anti-knock performance. It is worth noting that the gasoline grade has little to do with the quality of the gasoline itself. A higher grade does not mean the gasoline is better, nor does it indicate fewer impurities or higher purity. 2. Anti-knock performance refers to the ability of gasoline to resist knocking when burning in the engine. It is the primary indicator of gasoline's combustion performance. Knocking is caused by abnormal combustion of gasoline in the engine. The octane rating is the measure of gasoline's anti-knock performance; the higher the octane rating, the stronger the anti-knock performance.
