This is where this thread started. Play with your life on the highway if you wish, but please do not use this concoction in an airplane. If you must though, make sure you take no passengers, and stay away from congested areas. When your aircraft goes down in flames, make sure everyone knows you were using an experimental fuel so that the homebuilder community does not get a black eye.
Thank you.

That's a rant? There's way too much logic and rational thought for that to be a rant, at least according to internet standards.
