Should the Yamaha Fuxi 125 use 92 or 95 octane gasoline?
1 Answers
Yamaha Fuxi 125 requires 95 octane gasoline. The manual specifies the compression ratio, and motorcycles with a compression ratio of 9.5 need to use 95 octane gasoline. Whether a motorcycle should use 92 or 95 octane gasoline depends on the manual and the compression ratio of the motorcycle itself. If the engine compression ratio is between 8 and 8.9, 92 octane gasoline is required; if the engine compression ratio is between 8.8 and 9.8, 95 octane gasoline is needed. 95 octane gasoline has better fuel quality, and the engine's acceleration performance will be better. The engine's response speed is also faster compared to using 92 octane gasoline. The difference between 92 and 95 octane gasoline lies in the isooctane content. The higher the octane rating, the better the fuel's anti-knock performance. It is important to note that the motorcycle's fuel octane rating is limited by the manufacturer, so a higher octane rating does not necessarily mean the engine will perform better. The specific fuel label for the motorcycle should be selected according to the manual.
