hmmm. since the system is pressurized, i think it's capable of getting well 
over 100. plus, you're talking about oil temps, not water. though they're 
kind of related, there's no reason to think they equilibrate at the same 
temp. last, i would think a higher boiling point would make the system more 
able to dissipate hear and lead to a lower oil temp, but i can't back that 
up at all/don't feel like thinking about it.

you could still have some burping to do to--i've driven for a while before 
everything settled out. you could always run water wetter instead of a/f for 
corrosion protection. at any rate, a 60/40 mix is definitely overkill in 
s.c.
