Default Is draining the block enough to keep it from cracking....?
Star-Brite makes a number of anti-freeze products. While you are correct
about the freezing point of propylene glycol/water mixes, Star Brite has
other
additives. The MSDS for the -100 deg formula is here.

Note that the product contains 93% propylene glycol with no water so your
chart may not be applicable

They market a -200 deg product as well. I bet they work as advertised
though I've no experience with their products.
