Is There 98 Octane Gasoline?
2 Answers
Gasoline includes 98 octane gasoline, which has an octane rating equivalent to a mixture of 98% isooctane and 2% n-heptane. Different gasoline grades represent varying levels of fuel anti-knock performance, with higher octane numbers indicating better anti-knock properties. Introduction to 98 Octane Gasoline: This grade of gasoline can be produced by many domestic manufacturers, but it is not available at every gas station. Although relatively expensive, occasionally using it can provide benefits such as cleaning the fuel system. Introduction to Gasoline: Gasoline is a volatile and flammable liquid hydrocarbon mixture obtained from the distillation, cracking, or pyrolysis of petroleum. Its characteristics include volatility, stability, anti-knock performance, corrosiveness, and cleanliness.
Having driven for over a decade, I can say that 98-octane gasoline is available at many gas stations. Every time I refuel, I pay attention to the number on the nozzle—98-octane is that high-octane fuel, especially suitable for my old turbocharged car. After filling up with it, the engine sound becomes steadier, and there's no stuttering noise during acceleration. However, regular family sedans don’t necessarily need it. For engines below 1.5 liters, 92 or 95-octane is sufficient. I often remind my friends to check their owner’s manual—if the manufacturer recommends high-octane fuel, then using 98-octane is worth it. Otherwise, it’s just wasted money with little noticeable effect. In major cities, at Sinopec or PetroChina stations, 98-octane is pretty much standard, though it’s a bit more expensive—paying an extra yuan or two per liter is common. Overall, it’s quite convenient, so no need to worry about finding it.
