I have used vodka successfully.  a bottle in the tank, but I had drained
most of the tank.  This was when I had to park it in sub-freezing for a few
days without using it, and no power.  Worked great but had to do a few
flushes before refilling (weird taste).  I would prefer, but would never
waste in this way, Jack Daniels.
