You guys are awesome!  You could work on our spacecraft systems.

           Evans is mostly a mix of ethylene and polypropylene glycols, not
           significantly different than your regular antifreeze mixes, minus the
           absence of water. Straight water has a higher heat capacity than Evans
           or water + Antifreeze mixes. Glycols are used to provide freeze
           protection and antifreeze mixes include corrosion inhibitors. The
           boiling point of glycols is higher than water (or mixtures) so yes
           Evans can claim the vehicle won't boil over with water less coolant,
           but think about that for a moment... the engine is still running at
           that temperature, just the coolant isn't boiling, so in reality your
           fail safe of steam / boiling over to tell you have a problem has been
           eliminated! Damage is still occurring to your engine from running at
           elevated temperature! Evans evens say on their website the gauge temp
           may be higher!
        
           IMO Evans is basically a great marketing exercise to alleviate you from
           some of your wallet contents and nothing more. If you have an inherent
           over heating problem, spend your $$ to fix that by adding more
           cooling capacity (larger or more efficient radiator), move more coolant
           around (high volume water pump or overdrive pulley) etc., but Evans
           doesn't fix anything, it's a band aid approach that helps mask it!
        
           Evans should not be used in a vehicle to be used on track for the same
           reasons traditional glycols are not recommended as they leave a 'oily'
           slick residue if spilled.
        
           On the discussion of aluminum vs. copper I run Fluidyine aluminum
           radiators, but it is worth mentioning that many aluminum radiator
           failures are due to simple galvanic corrosion, thus it is well worth
           using a sacrificial lead anode in a mixed metals cooling system.

           Never heard of that risk but I will test the ignition temp of the stuff
           and report back
