I thought to make this a topic for Australian motorised bike users, as there is a government movement to remove 91 octane fuel from gas stations in Australia. The Government has decided to add 10% Ethanol to unleaded fuel. Calling it E10. And they are removing 91 octane from the market. Some cars can't use E10, any engine that has rubber gaskets will die. most 2 strokes can't use E10. I can't use E10!!! i have a starfire GenIIA 2 stroke motorised bike. I have a dellorto performance carby with rubber gaskets. E10 is going to slowly kill my carby. Does anyone know what we can use now? 95 octane? ???
