Is There 98 Octane Gasoline?

[DeLilliana]

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.

As a car enthusiast, I absolutely love talking about this. Of course 98-octane gasoline exists! Its high octane rating means superior anti-knock performance, making it ideal for high-performance engines like sports cars or modified turbocharged ones. I remember trying it on a long highway trip - the engine responded quicker and the throttle felt incredibly smooth, just amazing. Nowadays it's widely available in most countries, and you can find it at many gas stations in China too. But I have to watch the cost since it's more expensive - 95-octane is perfectly fine for regular sedans. For new car owners, I'd suggest checking the recommended rating on the fuel cap - higher isn't always better. Personally, I believe regular maintenance protects your engine better than just using premium gasoline alone.

After driving for a long time, I've encountered many gasoline choices, and the existence of 98-octane gasoline makes sense. It has a higher octane rating, mainly helping to prevent engine knocking, especially useful in summer or when climbing mountains. It's available at most gas stations in China, just a bit more expensive than 95-octane. From an economic perspective, using 98-octane for regular family cars is actually a waste of money, as fuel consumption may not decrease significantly. Car owners should develop the habit of checking the engine type and local climate before refueling—keeping it simple and cost-effective is the way to go. There's no need to follow the trend.
