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.

mfg often are required by gov't regulations to state a shelf life on a product. Now in some cases, there is a real shelf life, an example is DEF which depending on temperature has a shelf life of a few months to a few years.
In other cases rather than go through the testing to determine shelf life on long lived products,they create one.
The two compounds used for RV antifreeze are propalene glycol which has an very long shelf life under normal conditions or ethanol. Now ethanol has a shelf life of decades, even centuries.
If the antifreeze was sealed, I'd use it.
