What's the Difference Between 95 and 92 Gasoline?

[VonEmily]

95 and 92 gasoline mainly have the following differences: 1. The biggest difference between 92 and 95 gasoline actually lies in the different proportions of n-heptane and isooctane in the two: 92 gasoline contains 92% isooctane and 8% n-heptane; while 95 gasoline contains 95% isooctane and 5% n-heptane. 2. Due to the different proportions of n-heptane and isooctane in the two types of gasoline, it directly leads to the difference in their anti-knock performance. The gasoline octane rating actually represents the anti-knock performance, with a higher number indicating better anti-knock ability (this is because it contains more octane).
