2 Answers
Here are the differences between 92, 95, and 98 gasoline at gas stations: 1. Different octane ratings: 92 refers to gasoline with 92% isooctane and 8% n-heptane. 95 refers to gasoline with 95% isooctane and 5% n-heptane. 98 refers to gasoline with 98% isooctane and 2% n-heptane. 2. Different vehicle compatibility: 92 is suitable for vehicles with lower compression ratios; 95 is suitable for vehicles with higher compression ratios; 98 is suitable for high-end luxury cars and high-performance sports cars. Additional information: Here are some tips for choosing gasoline grades: 1. 92 gasoline is suitable for ordinary cars with low technical requirements. 2. 95 gasoline is suitable for the vast majority of cars. 3. 98 gasoline is suitable for high-end luxury cars and high-performance sports cars.
I often chat with fellow car enthusiasts about gas stations, and it's quite interesting. The numbers 92, 95, and 98 are essentially octane ratings, representing the gasoline's ability to resist knocking. The higher the number, the better it prevents the engine from pre-igniting under high pressure. If you drive a high-performance car or a turbocharged model, it's recommended to use 95 or 98 octane gasoline, which can make acceleration smoother and reduce engine noise. For regular family cars like economy models, 92 octane is perfectly sufficient, no need to waste extra money. I remember a friend once upgraded to 95 and complained that fuel consumption didn't drop much—this is actually because the engine wasn't matched, wasting money on fuel. The key is to check what your car's manual recommends; don't fall for gas station promotions. Different octane levels do offer varying levels of engine protection, but choosing the right one is the real way to save money. Using the correct fuel also improves the car's power response and drivability.
