Tell me this, what do you make of his claim that you can pour this stuff
straight into an airplane set up for Avgas? No timing or mixture
changes, no hardware changes?

If it really is a substitute for 100LL, then that would be exactly
what one would do.

A pretty big 'if', though. If he can really make the stuff, why is
he talking instead of mixing? If you can put avgas out at 1/2 the price
as he seemed to be claiming, he could get a lot of attention with a
pump pumping for $2.499 / gallon.

Of course, if he makes the stuff without lead, then I don't see why
it wouldn't work in most cars as well. At $2.499 / gallon, he could
sell all he could make.

*IF* he can do it.
