hi guys,,,, a few years ago in MORWELL victoria australia,, a guy opened up an independent service station selling 10% ethanol ,, i unknowingly purchased 50-60 bucks worth for my commodore wagon ,,, which ran like a charf cutter for about 30k ,,then as sweet as ever,, the exhaust looked like new after a week with it in the car,,, the only drama too me was he was dearer than any other sort of petrol in morwell,, which was a shame as our goverment was trying to push its use .. but no real support .. i used to use it about once a month ... as ir ran sweet .. ,,, i really don,t know about putting in my bikes regards oldbiker
