Is there 98 octane gasoline available?
3 Answers
As of now, major cities across the country have gas stations offering 98 octane gasoline. 98 octane gasoline refers to fuel whose octane rating is equivalent to a mixture of 98% isooctane and 2% n-heptane. Engines with high compression ratios should use high-octane gasoline; using low-octane gasoline in high-compression engines can cause abnormal combustion. Relevant information about gasoline is as follows: 1. Introduction: Gasoline is a volatile, flammable liquid hydrocarbon mixture distilled and cracked from petroleum, used as fuel. It appears as a transparent liquid, is flammable, and has a distillation range of 30°C to 220°C. 2. Key Characteristics: The important properties of gasoline include volatility, stability, anti-knock quality, corrosiveness, and cleanliness.
As a veteran driver with over a decade of experience, I've seen many fuel types, and 98-octane gasoline does exist. I remember during my trip to Australia, I saw the 98-octane option at gas stations, where they call it 'Premium Unleaded'. It has a higher octane rating suitable for high-performance vehicles. Higher-octane fuel can reduce engine knocking and improve combustion efficiency, making it particularly suitable for turbocharged or modified cars, resulting in smoother driving. In China, 95-octane is common, but 98-octane is more premium and naturally more expensive. If you drive a European import, the manual might recommend 98-octane gasoline, as it protects the engine and extends its lifespan. However, it's not available everywhere, depending on the gas station's inventory. For daily driving, 95-octane is sufficient, but if you're after peak performance, you might consider trying 98-octane.
After playing with cars for so long, there's no fuel I haven't seen. Of course, 98 octane gasoline exists and is quite common in Europe! High octane means better anti-knock performance, especially for sports cars or performance models like Porsche and BMW M series. Using 98 octane can reduce engine knocking and ensure more stable power output. I've driven a friend's modified car with 98 octane, and it felt noticeably quicker in acceleration response. In fact, the gasoline grade reflects cleanliness and efficiency—98 octane has fewer impurities and burns more completely, making it more environmentally friendly. Different regions have different fuel station supplies; most in China use 92 and 95 octane, but some imported car service stations occasionally stock 98 octane. It's best to choose fuel according to your car's manual—no need to experiment unless your car specifically requires higher octane fuel.
