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.

It doesn't generally go bad. The dye may fade or change over time, but the ethanol and/or propylene glycol doesn't break down, at least over the course of a few years, assuming the container is closed so the contents cannot evaporate. If it's a few decades old or has evidence of some weird slime growing or something like that, I'd probably pass, but otherwise it shouldn't be any problem at all.
This.
