Does RV antifreeze go bad?
My neighbor gave me some RV antifreeze he's had in his garage. It has been a year or so since he has had a RV so I'm not sure how old it is.

A "freeze test" is not a good way to test RV antifreeze. The propylene glycol and water mix it's made with will in fact freeze at some point. The difference compared to straight water though, is that the PG/water mix does not expand to cause damage when it freezes.
