Should the GW250 use 92 or 95 octane gasoline?
2 Answers
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.
