Modern fuels & older bikes

Had a mail yesterday,

Hi All,
Great news from Esso. Their new Shell Super Unleaded (Synergy Supreme+ Unleaded 97 and Synergy Supreme+ 99) both contail No Ethanol; although will be marked as E5 (UP TO 5% Ethanol). Not available everywhere. THIS is the fuel to use in your classic, high compression and carburetted motors.
