The following are the differences between 92 and 95 gasoline: In terms of n-heptane content: 95 gasoline contains 5% n-heptane; 92 gasoline contains 8% n-heptane. In terms of isooctane content: The octane rating of 92 gasoline is lower than that of 95 gasoline. 95 gasoline contains 95% isooctane; 92 gasoline contains 92% isooctane. 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 gasoline has better anti-knock performance than 92 gasoline.
