Thanks for the information Dave.
You got me wondering what would happen if the all of the fuel used
was Propane (BP -42.1) or Methane (BP -161.7) ??
With methane could you put a 500 HP hit on Jack's flathead? (Just kidding)
Seriously, I wonder if Av Gas with the max. TEL added would be a good idea.
Thanks again for the (as usual) excellent information,
Bryan
