I remember seeing an analysis of several different anti-freeze/coolant
products that were effective in improving coolant performance.  But,
for the life of me, I cannot find it.  Paul, did that come from your
list?  If so, could you re-post?

Best Regards,

Are you talking about Evans coolant?
Propylene glycol
Molecular formula     C3H8O2
Propylene glycol Boiling point     188.2 °C

Ethylene glycol Boiling point     197.3 °C (470 K)

Sorry for the confusion; what I was looking for (and I found) was a
report on wetting agents, not anti-freeze.  Here is the report from
Turbo Magazine that I found.  This seems to be an effective way to add
cooling system effectiveness.
