Yeah, I know I'm going to get flamed

I have read a lot recently about people burning everything from bio-diesel
and straight french fry grease to used ATF in ground based diesel engines
but what about flying turbines? I am quite sure that they would burn either
at ground level but will these fuels gel at the lower flight levels and
would the FAA have a problem with fuel type in an experimental aircraft?

Deltahawk discusses fuels for their piston aviation diesel. JP5 I think with
some lubricant I suspect to prevent cylinder washout. They mention regular
diesel with altitude/temperature restrictions due to gelling.
