And, knowing the attributes of both fuel types. Using non-ethanol fuel will give you the best results. It's simply a matter of physics. You just can't change physical realities with opinions.

However, the next potential fly in the ointment and legitimate question is, how much difference will using optimal fuel make over using the minimum requirement fuel? This is where the factual debate lies.
It will be small and not actually noticeable, really. Not worth the hefty price difference.
