The Difference Between 92 and 95 Gasoline

[SanMila]

92 gasoline and 95 gasoline differ mainly in the following three aspects: First aspect: Composition difference. 92 gasoline consists of 92% isooctane and 8% n-heptane, while 95 gasoline consists of 95% isooctane and 5% n-heptane. The primary 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. Second aspect: Stability difference. 95 gasoline has particularly good stability and is easier to burn. The octane rating of 92 gasoline is 92%, while that of 95 gasoline is 95%. 95 gasoline is highly flammable, so it is actually less fuel-efficient. The two types of gasoline should not be mixed, as mixing can cause engine problems and significantly impact the engine's lifespan. Third aspect: Applicable vehicle difference. When choosing between 92 and 95 gasoline, please refer to your car's manual for guidance. Generally, cars priced around 100,000 yuan can use 92 gasoline, while cars priced around 300,000 yuan require 95 gasoline to meet the engine's demands.
