What are the heat transfer specifics of MPG?  Is that the stuff that was
discussed a few months ago and said to have really poor heat transfer
attributes?
Remember the thread ... can't remember the "stuff" ... Jim S.

Dave,
I did a search on the web, and the MPG coolant is Mono Propylene Glycol.  It
is the non-toxic anti-freeze, and apparently it does have a much higher
boiling point.  Both Sierra and Amsol make one.  After reading about it, I'm
definitely going to get some.

One of the guys at the airport says that "all" the subaru guys are using
something called MPG instead of Ethylene Glycol/water because it boils at
290 without need to be pressurized.

Does anyone know anything about that stuff?
