Can the CFMoto 250 use 92 octane gasoline?
1 Answers
CFMoto 250 can use a minimum of 92 octane gasoline. Choosing the correct gasoline grade helps avoid engine knocking. Engine knocking: An abnormal combustion phenomenon inside the engine that affects power output and fuel economy. Causes of engine knocking: Occurs during the compression stroke when both intake and exhaust valves are closed, and the piston moves upward to compress the air-fuel mixture. The temperature and pressure of the compressed mixture increase. If the gasoline has poor stability, the mixture may ignite prematurely. The burning mixture pushes the piston downward while it's still moving upward, negatively impacting power output and fuel efficiency. Severe knocking can lead to connecting rod deformation or piston fracture.
