Most RV specific blends are good to -20 to -40. Keep in mind, it will slush below zero but it doesn't expand like water does. Water crystallizes, expands, and does its damage. The anti-freeze will slush but doesn't burst PEX lines. Next year, winterize with the antifreeze then blow the lines with compressed air, this is the method I use.
