I don't recall the brand name, it was purchased from the local auto zone store. I believe the label stated good to 40 below, it was regular RV antifreeze. Hopefully everything will be alright, I winterized the TT properly by making sure the pink came out of the faucets , then putting some in all the p traps. I will have my fingers crossed till spring, now I am second guessing myself , hoping I did everything rights. We are just having record lows here in eastern Va in the single digits. A lot of the Chesapeake Bay is frozen, most all the rivers have tons of ice in them. COME ON SPRING.
