Should the GW250 use 92 or 95 octane gasoline?

GW250 can use 92 octane gasoline. Gasolines with different octane ratings have varying levels of octane values. The higher the octane rating, the higher the octane value, and the better the stability of the gasoline. The primary factor to consider when choosing the appropriate gasoline for a motorcycle is the engine's compression ratio, as selecting the gasoline grade based on the engine's compression ratio is the correct approach. The GW250 is a motorcycle produced by Suzuki, equipped with a four-stroke, in-line twin-cylinder, water-cooled engine with an actual displacement of 248ml. The bike generates a maximum torque of 22Nm at 6500rpm, and the curb weight with a full tank of gasoline is 183kg.

My Suzuki GW250 typically recommends using 92-octane unleaded gasoline, as the vehicle manual clearly states that 92-octane is suitable and meets daily riding needs. The GW250's engine has a relatively low compression ratio design, so 92-octane fuel provides good combustion efficiency and avoids knocking issues. I've used 92-octane fuel for years during city commuting, with stable fuel consumption and smooth engine operation, and no malfunctions. 95-octane fuel has a higher anti-knock index and is more expensive. Occasionally using it makes the throttle response feel more sensitive and provides better power when climbing hills, but long-term use isn't cost-effective. I suggest checking the manual first to confirm the recommended octane. If it specifies 92-octane, don't unnecessarily upgrade to avoid wasting money. Regular maintenance and choosing reliable gas stations are more important.

I've tried both 92 and 95 octane fuel on my GW250. From a cost-performance perspective, 92 octane is more economical. It's cheaper, saving about ten bucks per full tank. The GW250 engine isn't high-end, so 92 octane is perfectly adequate. For daily commuting, it consumes around 4 liters per 100 kilometers. 95 octane has a higher rating and burns slightly more stably, reducing noise a bit during high-speed riding, but the extra cost doesn't necessarily translate to significant performance gains. My experience is that unless you frequently ride in hot areas or under heavy loads, 92 octane is sufficient. Remember not to use lower-octane fuel to prevent engine knocking and damage. Always choose reputable gas stations to avoid impurities when refueling.

Using 92 octane fuel is most suitable for the Suzuki GW250, as emphasized in the manual. 92 octane fuel is cost-effective, convenient to fill up, and provides quick engine response with no issues for daily riding. Trying 95 octane showed little difference, just costing more.
