P.S. To the above. If you want a "lose, lose," try isopropanol which is frequently sold as "rubbing" alcohol in the US. From what I've read (again, I am NOT a medical professional), it's more toxic AND it produces more soot when burned. Yep, here's the fuel you really (don't) want.

This is anecdotal, but a friend of mine was doing tests in his garage with isopropanol. He had to stop because he was feeling ill. He didn't feel 100% for a couple of days.

Therefore, last choice, emergency use only: Isopropanol.
