There is a LOT of snake oil out there.   I am not saying that NPG is
snake oil, really haven't looked into it, but it is likely not optimum

for

cooling engines designed for EG/water 50/50 mix.

Take another look at all the charts on this subject I have uploaded
recently.

I guesss, I don't understand this search for a different coolant medium.
So far as I know, no commonly available liquid has a higher specific heat
value than water.  Even mixing antifreeze with water effectively lowers the
amount of heat the coolant can absorb as anitfreeze does not have as high a
specific heat value as water.  So regardless of the boiling temp of the
cooling liquid, if the specific heat value is lower then less heat is
transported from the metal into the liquid per unit volume. While a higher
boiling temp does permit more heat to be transfered to the cooling medium
before it boils, this does not necessarily mean that it transfers heat more
efficiently than water.  There may be some applications where the higher
boiling temperature is critical, but for ours?? What am I missing??
