What are the characteristics of 95-octane gasoline?
2 Answers
95-octane gasoline is characterized by containing 95% isooctane and 5% n-heptane. The higher the octane number, the greater the content of isooctane, and the stronger the anti-knock performance of the gasoline. Gasoline is a volatile and flammable hydrocarbon mixture liquid obtained from petroleum through fractionation, cracking, or pyrolysis, and can be used as fuel. Characteristics of gasoline: 1. Volatility: It rapidly vaporizes in the engine cylinder and forms a uniform combustible mixture with air; 2. Stability: The ability to resist oxidation under normal temperature and liquid phase conditions is called stability; 3. Anti-knock performance: Refers to the ability of gasoline to resist detonation combustion under various usage conditions; 4. Corrosiveness: Sulfur compounds in gasoline can cause corrosion to objects.
I've been driving a Volkswagen Golf for five years and always use 95-octane gasoline, which feels quite reliable. The octane rating of 95 means it has the highest anti-knock performance, preventing engine knocking during high-speed driving or climbing hills. Engine knocking sounds like the engine is firing randomly, which can damage the engine and shorten its lifespan. The 95-octane fuel burns cleaner, and my car's fuel consumption has dropped by an average of 5%. On the highway, the throttle response is quicker, and acceleration feels smoother. Although the price per liter is 1-2 yuan more expensive than 92-octane, it saves money on repairs in the long run. I often add fuel system cleaners at gas stations to remove carbon deposits and reduce emissions. Remember to choose fuel according to the car manual's recommendation—don't risk using lower-grade fuel just to save money.
