What grade of gasoline should be used for the BMW G310R?

[SanZane]

BMW G310R should use 95-octane gasoline. The following is an introduction about gasoline: Reasons for using 95-octane gasoline: BMW recommends using 95-octane or higher gasoline, which ensures complete combustion, reduces carbon deposits, and provides quick acceleration response. 95-octane gasoline consists of 95% isooctane and 3% n-heptane. When the engine has a high compression ratio, high-octane gasoline should be used. Using low-octane gasoline in a high-compression engine can cause abnormal combustion, leading to knocking, increased fuel consumption, and reduced driving power. Differences between gasoline grades: Currently, the gasoline grades available on the market are 92, 95, and 98, corresponding to different octane ratings. The higher the octane rating, the better the gasoline's anti-knock performance. When the air-fuel mixture is injected into the engine cylinder, the piston moves upward, and the compressed mixture's temperature rises. If the anti-knock performance is insufficient, the mixture may start burning before the spark plug ignites due to temperature and pressure, causing knocking.
