At the risk of being completely full of shit, I believe propelene
glycol is what's used for antifreeze in potable water systems, RV's
etc... available in gallon quantities at relatively reasonable costs.
  Also have heard that propelene is highly flamable, as in if a hose
blows and gets on a exh manifold you're in for some excitement.
If t were me using it knowing only what I know now, you can bet
I'd be keeping a close eye on hose condition...
Anybody got come chemical specs handy??
