If you want spectacular ignition, go to the local airport & get a gallon of avgas to use. I believe it's between 115 and 125 octane. Should blow up quite nicely!

Not much.bout how much of the 4:1 - 6:1 diesel:gas mixture would a person need for a pile of this size?
We forget how to do things that we haven't been taught to do(I cannot believe, 1 million years after homo erectus [back in the Pleistocene geological epoch] learned how to make and control fire, that modern man is questioning how to do it)
