Does the Saiying 125 require 95 octane gasoline?
1 Answers
The type of gasoline to use mainly depends on the engine's compression ratio. For motorcycles with an engine compression ratio below 9.5:1, 92 octane gasoline is sufficient. Of course, using 95 octane gasoline is also acceptable and won't cause any issues, but it is unnecessary as it doesn't provide better performance and only leads to waste. Below is relevant information: Compression Ratio: If the motorcycle's engine compression ratio reaches or exceeds 9.5:1, it is suitable to use 95 octane gasoline. The octane rating of gasoline does not indicate the quality or cleanliness of the fuel, and blindly using higher octane gasoline is pointless. Gasoline: Gasoline is a volatile, flammable hydrocarbon mixture liquid distilled and cracked from petroleum, used as fuel. It appears as a transparent liquid, is flammable, with a distillation range of 30°C to 220°C, and its main components are C₅~C12 aliphatic hydrocarbons and cycloalkanes.
