I would not use it in an attempt to compensate for cooling issue(s). Prior to our decision to "invest" in this product, we talked directly to Model A drivers in South Texas who drive their "A's" in 100+ degree heat with no worries with Evans Coolant.
PS The back cover of Snyder's 2020 catalog shows a photo of our car reaching the summit of Donner Pass.

There is absolutely nothing in Evans coolant that increased your car's
cooling reliability on that trip. In fact due to Evan's lower heat capacity, you hindered, not helped your cooling system. The benefits from a no water coolant are corrosion and temperature range related, not thermal efficiency.
The level of reduced thermal capacity obviously did not rear its head for your trip, but please don't use that experience as a qualifier for the benefits of this expensive product.
Glycol has less heat capacity than water.
