I would suggest going back and rereading the last 4 pages of posts. The ethanol is there not only to satisfy regulation, but is used to raise the octane of the fuel feedstock to create the finished fuel. Removing the ethanol also substantially lowers the octane. While your aircraft is apparently burning it without detonation issues so far, that is no guarantee the next can as you really don't know what octane you have in your now scrubbed fuel.
