I work for a marine supplier. Had one of the places say they wanted X type of AF as it supposedly only turned to slush. So it would not damage the boats motors! Much more expensive than waterlines in RV's. They put a cup of both the stuff they preferred, and one that we sell about 100 to one vs what they wanted. The one sold the most, was actually softer than the one they wanted, and a bit cheaper too.
At the end, both work well. Granted we only usually have temps in Puget Sound into the 20F relm, had a few pushing 5-10F around here in the last week.
Another buyer will only use -100 as they think it will protect them more from cracking motors.
Reality, if the AF freezes per say, but does not expand, it is not an issue for anyone, whether you put it into an engine cooling system, or the water lines.
Just make sure you use the types for waterlines that are not poisonous to you or other animals if you dump it on the ground after use, or in the case of a trailer able boat motor, when you turn on the system in the water, it will not hurt the water you are in.
