Does Mixing 92 and 95 Octane Gasoline Have Any Impact?

[AlanFitz]

Strictly speaking, 92 octane gasoline and 95 octane gasoline should not be mixed. Here are the differences between 92 octane and 95 octane gasoline: 1. In terms of n-heptane content: 95 octane gasoline contains 5% n-heptane; 92 octane gasoline contains 8% n-heptane. 2. In terms of isooctane content: 95 octane gasoline contains 95% isooctane; 92 octane gasoline contains 92% isooctane. 3. In terms of anti-knock performance: Different gasoline grades represent different fuel anti-knock properties. The higher the gasoline grade, the better the anti-knock performance. 95 octane gasoline has better anti-knock performance than 92 octane gasoline.
