There is no simple answer. If I were you I would contact the
manufacturer(s) of your engine and fuel system (tank, hoses, pump,
carb/injectors, etc.). At best you will likely get the maximum %
ethanol each component will tolerate. That should be good enough for
your purposes. Although I'm not sure why you want to know "in all
percentages". That may be asking too much. Are you saying that you
*plan* to run all percentages (0 to 85) in your aircraft? You do
realize that significant mixture adjustments must be made over that
range? How will you compensate for that?

I don't plan on doing it that way.

what I am trying to figure out is what would need to be replaced if I
decided to go from X% mix to a Y% mix. currently autogas can contain 10%,
but if I want to convert my truck so it can run 50%, what will I need to
replace?

ten bucks says that the manufacturers will stick to 10% and say anything
over that will void warranties, without bothering to see if that really is
the case.

yes, truck. I assume the same thinking goes into aircraft. been to Oshkosh,
cant afford a plane(yet!)
