Should a 125cc scooter use 92 or 95 octane fuel?

[VonEdward]

For a 125cc scooter, both 92 and 95 octane fuel are suitable. Reference for motorcycle fuel grade selection: For many small and medium-sized motorcycles, 92 octane fuel is commonly used. However, using 95 octane fuel can provide better acceleration performance. Compared with 92 octane fuel, it offers faster power response and causes less engine vibration. The difference between 92 and 95 octane fuel lies in their iso-octane content. Higher-grade gasoline has better anti-knock performance. 95 octane fuel is purer than 92 octane, releasing more kinetic energy during combustion in the engine. Therefore, higher-grade fuel demonstrates better fuel efficiency and longer range in terms of power delivery. Motorcycle refueling precautions: For motorcycles below 150CC, the engine oil capacity is mostly less than one liter. Never overfill the engine oil - the correct amount should be checked using the oil dipstick or observation window. Overfilling engine oil may cause engine overheating, oil leakage. Never fill the engine oil to maximum capacity. Do not arbitrarily switch fuel grades. If you switch to a lower grade fuel, it may cause premature combustion and engine knocking.
