 Is it viable?
 Do you have any experience with that?

 Some people have run it successfully but I recommend a thermal couple be
 placed close to the lower spark plug to monitor the "cylinder" head
temp.

Thanks, Paul.

The website shows that Evans Coolant has only HALF the thermal
conductivity of a 50/50 water/ethylene glycol mix.  I'm no engineer, but
halving the rate at which the coolant extracts heat from the block
appears to be a move in the wrong direction.
Their claims of increased efficiency comes ENTIRELY from a lower duty
cycle of the engine-driven cooling fan on large diesel trucks.  They
make NO claims that cooling is improved.

I am aware of that. The higher boiling temperature may over ride
that drawback for aircraft engine use. Boiling cannot be allowed
in an aircraft engine. As long as the metal temperature near the combustion
chamber around the lower spark plugs remains below 500 F it is OK.

Mark S has installed thermal couples in this area. So did Mazda
and NASA.
