Would Higher Octane Run the Gen Better? UPDATE

It should be noted that ethanol provides an octane boost along with an energy density loss to any gasoline mix. I don't expect that merely higher octane fuel would offer an improvement, but a no-ethanol gas might. I don't know about BC, but here in the states, at least on the East Coast, no-ethanol gas is available, but you have to search for it. It is not usually needed for cars, but small engines often do better with it.
