How Long will RV antifreeze last
I had a few family issues this summer. I didn't get to use my travel trailer. I winterized it last year. Will it stand another winter with the same antifreeze? thanks

I googled "shelf life of propylene glycol for RV" and found a Dow Chemical MSDS (Material Safety Data Sheet) that states a shelf life of 2 years. Apparently, storing it higher temperatures shortens the life.
