Hi,
If you do a search of the Forum you will find quite lengthy discussions about ethanol in petrol and especially E10. There did not seem to be a conclusion so it is probably a matter of try it and make up your own mind.
Maybe I have been lucky but when lead was removed from petrol I just used unleaded and when E5 came I just put that in and the same with E10. Occasionally a tank of Super Unleaded will go in the tank as the extra additives help to keep the carb and combustion chamber a bit cleaner.
Dave.
