Does antifreeze have a shelf-life

I found two containers of Prestone in the cellar. Probably were my father's and he passed in 1983, so almost 40 years old. Okay to use, or just bring to a auto garage to dispose?
 

Neat Antifreeze has no shelf life at all.. as long as it's tightly closed.. and not in any way mixed with water.
I was trying to remember my chemistry and then I remembered a murder case where a lady killed her boyfriend by serving him drinks laced with antifreeze. The jug must have been 20 years old. I forget how old it was, but I remembered that it had a very old label on it.
