I have been working on a project to remove ethanol from auto fuel and have been having good luck removing it by (1) Testing for percentage of ethanol in pump gas. (2) If present, I mix in the appropriate amount of H2O (Yes - WATER) (3) Letting it combine with with the ethanol,by agitating it. (4) When it mixes and settles to the bottom of my mixing tank, I drain it off an pour it into my truck (which has E-85 capability). I then go through the process again. When it tests as having no ethanol (I haven't had to run it through the de-ethanolation process a 2nd time.) I pour it into my storage tank and run it in my antique motorcycle.
Once I get my new aircraft engine broken in I'm going to start mixing it into my aircraft fuel and plan to run it as a blend with LL-100 at a ratio of 4 to 1 [To get the lead for valve lubrication.]). Based on the fact that I check my tanks for water before use, I think it will work fine.
The removed ethanol zips through my trunk (and it's extra water filter), without a hic-up I figure I lose a little ethanol and my cost of pure gasoline for other uses (motorcycle and airplane) only increases about 5 to 10%.
Yes, it is slightly labor intensive (I'm retired and have more time than money.) but, when avgas costs over $5/gallon and my converted (ethanol free) auto fuel costs $3.75/gallon so, I save a fair bit of money.
