Unwanted and imposed E10 put me off when it melted the polycarbonate prism attached to the fuel cap on my Victa and would fall right onto the fuel outlet of the tank, blocking flow and making a gooey mess at the bottom.
I have heard that it will gradually separate in the tank if it sits for a long period unused. The NSW "govmint" have forced petrol stations to take a minimum amount of E10 from their friends with the only ethanol plant in the state.

Ahh, if only victa had kept producing the thumblatch catcher series, they would be in better shape today!
