What happens when you mix 95 and 98 gasoline?

[MacJulianna]

Mixing 95 and 98 gasoline can result in reduced acceleration performance. The differences between 98 and 95 gasoline are as follows: Different composition: 98-octane gasoline is composed of 98% isooctane and 2% n-heptane, while 95-octane gasoline consists of 95% isooctane and 5% n-heptane. The main difference lies in the purity of isooctane. The higher the purity of isooctane, the stronger the gasoline's anti-knock performance, and consequently, the higher the price. Different stability: Both 98-octane and 95-octane gasoline have excellent stability, but 98-octane gasoline is more prone to combustion and has superior stability. The octane rating of 98-octane gasoline is 98%, while that of 95-octane gasoline is 95%.
