Can anyone tell me,if it is ok to use e10 fuel(australia)in a 2 sroke 50cc scooter?

will it damage the motor?or be better for the motor?

Be sure the oil to fuel ratio, and the carb jetting is correct for your type of motor. You should be good to go.

Try it. It should work. Mite burn something out in the long run but in will go for now.
