My issue just came today and there are three good articles pertaining to fuel for aircraft--- Fueled by Ethanol,Life After Avgas, and Greg Poe And His MX2. Life after Avgas talks about Sweden's 91/96 UL avgas----just think, blending that with 20 or 30% ethanol could get it up in the even higher 90's octane and not lose as much range as straight ethanol.
