We have 3 places that supply non ethanol fuel in this part of the world. The trouble I have, if one was to be completely anal about the whole situation is that at 2 of the 3 it is delivered on the forecourt through a blender pump. This means the first 1,2,3????? litres are whatever the last guy pumped. Only one has a dedicated hose only for their high octane non ethanol fuel.
My attitude is that if I am out and about and using the bike consistently I will run the (10%) ethanol fuel but try to top up with non ethanol if I am going to leave it parked for a while - like the winter. My C Rapide ran about last Feb 2020 and 2 weeks ago I started it up. Second kick on the fuel that was in it for 16 months. That was the stuff from the non blender pump.
