Should motorcycles use 92 or 95 octane fuel?

Motorcycles should use 92 octane fuel. Difference between 92 and 95: The main difference lies in the octane rating, which indicates the fuel's anti-knock performance. The higher the octane number, the better the anti-knock performance, making it less prone to engine knocking. Motorcycle refueling restrictions: At regular gas stations, motorcycles must meet certain requirements to refuel. First, the station will check if the motorcycle has a license plate - motorcycles without plates will not be refueled. Additionally, gas station staff will inspect both the motorcycle's registration certificate and the rider's driver's license. Both documents are mandatory, and only when these conditions are met will the gas station refuel the motorcycle.

I also pondered this question when I first got my motorcycle. Most people recommend using 92-octane gasoline because it's cost-effective and widely available, perfectly sufficient for everyday commuting. If the motorcycle's compression ratio isn't high, 92-octane is just right, unlike higher-octane 95 which would be a waste of money. I checked the user manual, which emphasizes choosing fuel based on the engine design—if it specifies 92-octane, don’t arbitrarily upgrade. In daily riding, using 92-octane for city roads is completely fine, and even occasional long trips pose no risk. Modern motorcycles have ECUs to adjust for knocking, so they have strong compatibility. Remember, using the wrong gasoline long-term might affect spark plugs or cause carbon buildup, but initial issues are rare. The key is to follow professional advice and not blindly chase higher octane ratings.

As a seasoned motorcycle rider with years of experience, I'm accustomed to using 92-octane gasoline unless it's a high-performance model. The octane rating affects anti-knock performance—95-octane is suitable for high-compression engines to reduce knocking, but for most street bikes with a compression ratio around 10:1, 92-octane works perfectly fine and saves money. I once tried 95-octane and noticed no improvement in acceleration, just higher fuel costs. The most reliable approach is to check the user manual or the recommended octane rating printed on the fuel cap. Some riders believe 95-octane is "cleaner," but in reality, pollutant levels are similar—it mainly depends on engine tolerance. If you frequently ride aggressively on mountain roads, higher-octane fuel might optimize performance, but for regular commuting, it's better to save money and hassle.

I always emphasize safety first, and the type of fuel to use depends on the vehicle model. Regular motorcycles run smoothly enough on 92-octane gasoline, while 95-octane, though premium, is unnecessary. Misuse may lead to power loss or engine knocking. I recommend beginners prioritize the manual guidelines and ignore gas station promotions. 92-octane is cheaper and widely available in most regions, reducing the risk of suddenly running out of fuel. Occasionally, 95-octane can alleviate mild knocking on highways, but don’t overcomplicate daily commutes. A well-maintained engine usually adapts to lower-octane fuel, and regular oil changes to ensure lubrication are more critical.
