I run 91 octane no-ethanol in the BMW airhead bike and ALL my lawn equipment.
I'd run it in the Spyder, but I need the 93 octane...
So that's what I run, unfortunately it has ethanol.
Fortunately, my fuel pickup, pre and post filters, fuel pump, pressure regulator, fuel rails, injectors, metal lines (Nickel-copper) and braided EFI hose are all compatible.
