What Happens If a Motorcycle Uses 98 Octane Gasoline?
2 Answers
Using 98 octane gasoline in a motorcycle will not cause harm. 98 octane gasoline consists of 98% isooctane and 2% n-heptane. Engines with high compression ratios should use high-octane gasoline. If a high-compression engine uses low-octane gasoline, it may lead to abnormal combustion, causing knocking, increased fuel consumption, and reduced driving power. Relevant information about gasoline is as follows: Introduction: Gasoline is a volatile and flammable hydrocarbon mixture liquid derived from petroleum through distillation and cracking, used as fuel. It appears as a transparent liquid, is flammable, and has a distillation range of 30°C to 220°C. Key Characteristics: The important characteristics of gasoline include volatility, stability, anti-knock properties, corrosiveness, and cleanliness.
I've been riding motorcycles for several years and once tried using 98-octane gasoline. During that long highway trip, I noticed the engine noise became quieter and acceleration smoother, as higher octane reduces knocking and enables more complete combustion. But honestly, the cost is too high - my Honda CB150 has a small tank, and each fill-up costs dozens more than 92-octane. For daily commuting, it's simply not necessary. Since the manufacturer's manual recommends 92-octane, I've switched back to standard fuel - the savings are enough for maintenance. I suggest checking your motorcycle's user manual rather than blindly pursuing higher octane. Unless you frequently ride highways or race tracks, it's just wasting money.
