"Pshaw" is absolutely correct, Brett. Water has the highest heat capacity
of any substance on the face of the earth. The heat capacity of all other
substances is measured by comparing it to water, Specific Heat being the
ratio of the amount of heat required to raise a unit weight of a substance 1
degree to the heat required to raise a unit weight of water 1 degree. By
def. water has a Specific Heat of 1, all other substances being <1. Alcohol
is second best with a SH of .65 to .70, most other substances solid, liquid,
or gasous are <<.5.
Therefore coolent additives can only degrade a water's heat transfer
performance, and are used only to inhance other properties such as corrosion
resistance, boiling point, etc. Don't use more antifreeze in your mix than
is needed for freeze protection in your enviroment! And don't pay for any
other exotic claims, unless your wallet needs thinning.
