What grade of gasoline is recommended in the Suzuki UU manual?

[StAthena]

Suzuki UU manual recommends using 95-octane gasoline. Here is the relevant introduction: Gasoline grade: The ratio of the actual gasoline's anti-knock performance to that of standard gasoline. The higher the grade, the stronger the anti-knock performance. Standard gasoline is composed of isooctane and n-heptane. A higher grade is not necessarily better; the appropriate gasoline grade should be selected based on the engine's compression ratio. Anti-knock performance: 95-octane gasoline has a higher octane number. The higher the octane number in gasoline, the better the anti-knock performance for the engine. Under normal circumstances, the higher the engine's compression ratio, the higher the corresponding gasoline grade should be. This is mainly because a higher compression ratio leads to increased pressure and temperature in the cylinder, making the air-fuel mixture more prone to combustion and increasing the likelihood of engine knocking.
