As stated, there is data and marketing BS combined, such as the claim to not have corrosive oxygen like water. I believe that at least some of the Evans products are glycol-based, so have oxygen-containing molecules. While it might be amusing to calculate heat transfer coefficients from Reynolds numbers and viscosities (what shear rate do you want to assume?), I'd guess an empirical evaluation on a test rig measuring the temperature in and out at known flow rate was done somewhere.

The previous poster's advice is solid science, not marketing. I believe that these coolants prevent boiling by having a higher boiling point. That doesn't mean your engine is necessarily running cooler. It takes a higher heat transfer rate both from the engine and from the radiator to do that

What does the Forum think about Water Wetter?. I am not an agent or associated with this product but have introduced it to my vehicles over the past 12 months for anti corrosion purposes. It appears to work very well. I would very much appreciate some no BS comments from the coal face. Theorists are ok but please qualify any advice. Any research info whatever on this product would be appreciated. I would be particularly interested in any research regards its compatability with head gasket sealants. I was quoted $70,000 to get my 1934 P11 ( 3,131 miles from new) working because of a corroded head but have managed to stem the flow from radiator to sump from 3 quarts per day to less than 1 ounce per two days.

In case you wanted to know what a P11 is, for reference, here are a few photos. It spent a lot of its life in a museum, hence the low mileage.
