What is the Difference Between 95 and 92 Octane Gasoline?

[Gertrude]

95 and 92 octane gasoline differ in the following ways: 1. Different composition content: 92 octane gasoline consists of 92% isooctane and 8% n-heptane, while 95 octane gasoline is composed of 95% isooctane and 5% n-heptane. 2. Different anti-knock properties: The gasoline octane number represents its anti-knock performance. A higher number indicates better anti-knock capability, with 95 octane gasoline having superior anti-knock properties compared to 92 octane. 3. Different prices: 95 octane gasoline is more expensive than 92 octane. 4. Different power performance: The higher-octane 95 gasoline is suitable for engines with higher compression ratios. This is because as the engine speed increases, the ignition timing in the cylinder advances. When the speed reaches a critical point, the air-fuel mixture may ignite prematurely before the spark plug fires.
