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.

Seeing as how vehicle manufacturers recommend changing coolant between 100,000 and 160,000 miles which might correlate to 10 years of severe duty, I don't think I would worry much about some virgin coolant in a jug.
well, rv antifreeze is entirely different than vehicle antifreeze,
RV is either propalene glycol or ethanol, vehicle antifreeze is ethalene glycol, very poisanous, along with other additives, and it is a sealed system.
But a sealed or even open rv antifreeze jug that has been kept capped should be good for decades IMHO.
