> Has anyone tried a correctly engineered propylene glycol coolant?
The Evans system (no water=no corrosion) sounds very promising.  Check
it out at: http://www.evanscooling.com/

kinda odd to see the claims that they are making for prop. glycol ....
what i've heard (and read on the backs of the containers) is that p.
glycol is NOT as efficient as the ethylene glycol ... that is, a
e.glycol mix goes to lower temps in winter and higher temps in summer
(than the p.glycol mix). this sounds like the same old Sierra p.glycol
mix of a few years ago. the package kinda looks like it, too.

only thing i saw with p.glycol was that it wasn't poisonous to animals
and people ... the e.glycol is definitely poisonous.  :(
