Is 95 Octane Gasoline More Durable Than 92 Octane?
1 Answers
95 octane gasoline is not more durable than 92 octane. The octane rating represents the anti-knock performance; a higher number indicates better anti-knock capability, but it has no relation to the quality of the gasoline itself, nor does it mean that higher octane gasoline has fewer impurities. Some people may feel that using 95 octane gasoline improves their car's performance, but this is merely a psychological effect. Differences between the two: The main difference between 95 and 92 octane gasoline lies in the different proportions of chemical components, resulting in variations in octane value, fuel consumption, and price. 92 octane gasoline consists of 92% isooctane and 8% n-heptane, while 95 octane gasoline consists of 95% isooctane and 5% n-heptane. A higher octane value indicates better anti-knock performance. 92 octane gasoline has a slightly lower octane value than 95 octane. The anti-knock performance of 92 octane gasoline is relatively weaker, requiring a delayed ignition angle, which leads to faster fuel consumption in the car. In contrast, 95 octane gasoline has stronger anti-knock performance, resulting in slower fuel consumption. 92 octane gasoline is suitable for engines with a compression ratio between 8.6 and 9.9, while 95 octane gasoline is suitable for engines with a compression ratio between 10.0 and 11.5.
