i aint touchin this topic!
but i have used it in 3 different engines without any problems!
follow directions , and works out OK!
100% No corrosion, will not boil, until engine coolant reaches 375/400*F, by then you have other things to think about!
altho it seems to work better in hot climates, it is an oil, so gets thick in cold weather!

what andrew said, true.
ethylene glycol developed for Allison 1710, late 30s
propylene glycol , Evans coolant developed for SR71 Blackbird (hydaulic systems), 85000 ft its gets cold, but temps inside get super hot, skin friction starts to glow red,Titanium! not good to have anything boiling.
speed around 10,000 mph,?

if any interest, i used Evans for 11yrs in a turbocharged Rotary engine, maybe added a cup full of Evans.
and when i drained coolant it was a clear amber color,(like color of beer), 11 years!
seals and bearings perfect, cooling pump, no corrosion anywhere in the system, same hoses as i started with.
490whp, drained system , because sold the engine to a guy, and put same fluid back in, filtered 1st.
now things i learned , you need a good hi volume/hi pressure pump, stuff gets thick when cold (minus 40F and down).
No hi pressure cap, i run a 7 lb cap. room for coolant expansion, large resevior tank.
some run no pressure atall, open vent! maybe a catch can?
negative ; banned at all race tracks, if it leaks on to track , its a veg oil, slippery as ice,
so that means a good system.
and if you have dog/cat drinks any no problem(non poisonous)ethylene will kill them.
