Nothing in the article contradicts my recommendation to increase the
ration of coolant to water by adding pure coolant.  The system now has
30% coolant and 70% water.  The article shows an increase in
protection against freezing all the way up to 60% coolant.

Incidentally, pure coolant does not transfer heat as well as water.
The way I understand it, pure water is a better medium from a pure
heat transfer standpoint, but is not good for the water pump or
metallic system components.  I have run all of my vehicles with a
50/50 mix for thirty years, including some brutally cold Chicago
winters.  No problems yet.
