Comments about 100F Engine & Water System Antifreeze:
might as well get that extra protection. I even tested the product. I mixed a cup of water and a cup of -100 anitfreeze together and stuck it in my freezer for a couple days-it didnt freeze. Its a extra piece of mind knowing if there was any left over water in my engine that somehow didnt make it out while winterizing, it would be OK.
