Robert and all,
Here's a useful link courtesy of Bob Putnam. It provides dry/wet boiling points of some popular brake fluids and other information.

By the way, I am using the Valvoline
Synthetic in my Cobra and Mustang Cobra. I agree with Robert that it has some good properties, not hyper exepnsive, readily available, and is NOT Dot 5 "
synthetic".
