What grade of gasoline should the CM300 use?
3 Answers
Honda CM300 has a compression ratio of 10.7, and 92 octane gasoline is sufficient. Below is some relevant information about the Honda CM300: Power: In terms of power, the CM300 is equipped with a single-cylinder, water-cooled, four-valve, fuel-injected engine with an actual displacement of 286ml. It is paired with Honda's PGM-FI fuel injection system, achieving a fuel consumption of 2.92L per 100 kilometers and a designed top speed of 134km/h. Configuration: Currently, mainstream configurations can be found on this model, such as an LCD instrument panel, LED lighting, dual-channel ABS, and a slipper clutch, all of which are equipped.
I've been riding my CM300 for almost two years, always using 92 octane gasoline, and it feels just right. The engine's compression ratio isn't high, so 92 octane's anti-knock performance is perfect, offering the best cost-performance ratio. It's convenient to refuel and saves money. Using 95 octane is also possible, but it's more expensive and unnecessary for daily commuting. The Honda manual recommends 92 octane or higher, so 95 is acceptable, but 92 works perfectly fine. For maintenance, regular checks of the spark plugs and oil filter are essential to ensure clean combustion of the air-fuel mixture. In short, following the manual ensures both safety and economy, making for a smooth ride.
When using the CM300, I always fill it with 92-octane gasoline to save money and hassle. It saves me dozens of yuan on fuel costs each month—small savings add up over time. I’ve tried 95-octane occasionally, but the power boost was negligible, making it feel like a waste of money. Honda designed this bike to run on regular gasoline, so 92 is more than enough for city riding. Just make sure to refuel at reliable stations like Sinopec or PetroChina for better fuel quality. Avoid lower-octane fuel as it may harm the engine. Always keep an eye on your bike’s condition—smooth and steady riding is what matters most.
