Should the Kymco CT250 use 95 or 92 octane gasoline?

[EmersynAnn]

Kymco CT250 should use 92 octane gasoline. The gasoline grade represents the octane rating of the gasoline. For example, 92 octane gasoline consists of approximately 92% isooctane and 8% n-heptane. Since isooctane has better anti-knock properties while n-heptane has poorer anti-knock properties, a higher octane rating indicates better anti-knock performance of the gasoline. Therefore, the engine's compression ratio must be considered when selecting the appropriate gasoline grade. Gasoline is a volatile and flammable hydrocarbon mixture liquid obtained from petroleum through fractionation, cracking, or pyrolysis. At room temperature, it appears as a colorless to light yellow, easily flowing liquid that is difficult to dissolve in water and highly flammable. Mixing different grades of gasoline can lead to incomplete combustion, carbon deposits, and shortened engine lifespan.
