What are the effects of mixing 92 and 98 gasoline?

[VonBrooklyn]

Effects of mixing 92 and 98 gasoline: 1. If the vehicle's specified gasoline grade is 92, mixing with 98 gasoline is acceptable, but long-term mixed use is not recommended; 2. If the vehicle's specified gasoline grade is 95 or 98, long-term use of 92 gasoline is not advisable as it may increase the frequency of knocking and accelerate engine wear. The gasoline grade represents the octane rating of the gasoline. For example, 92 gasoline consists of approximately 92% isooctane and 8% n-heptane. Since isooctane has better anti-knock properties while n-heptane has poorer anti-knock properties, a higher grade indicates a higher octane rating and better anti-knock performance of the gasoline.
