Does mixing 92 and 95 octane gasoline have any impact?

[DavidLynn]

Mixing 92 and 95 octane gasoline does have an impact. Below are the relevant details: 1. Basic composition: From the perspective of basic composition, 92 and 95 octane gasoline differ in the ratio of n-heptane and isooctane. 92 octane gasoline consists of 92% isooctane and 8% n-heptane, and the same principle applies to 95 octane. 2. Additives: The additives are quite particular, mainly addressing the issue of gasoline's anti-knock properties. 92 octane gasoline is relatively cheaper and often contains higher levels of olefins and aromatics in its additives. You don't need to worry about what these substances do; just know that they tend to cause more carbon deposits after combustion. In contrast, 95 octane gasoline typically uses pure isooctane as an additive to maintain better anti-knock properties, resulting in fewer carbon deposits.
