I know this topic has been visited here before, and some feathers even got ruffled over it. Is the current thinking with new fuel tanks from Kitfox still the same? i.e. that ethanol-containing fuels are highly discouraged?

I ask because the nearest place I can get ethanol and lead-free 91+AKI fuel is a 3 hour round trip by car. There is 90 AKI ethanol free that's a 1.5 hour round trip. In either case, I don't save any money vs. burning 100LL/Decalin, even when you factor in the reduced oil change and spark plug intervals.

The only unleaded fuel I can reasonably use would be 10% ethanol. If I could use it, it would save me about $15/hour, and the hassle of oil changes every 25 hours. But obviously it's not worth gumming up my fuel system with a nice epoxy varnish.
