I added it. Some people believe in air only winterization. I believe in the pink stuff. In addition to my Motorhome, I have a 46' boat I have to winterize. I use about 5 cases of the pink stuff between both. For under $100 for all 5 cases ($3 gallon at Tractor Supply), I sleep much better...

coldest winter ever last year, never did anything to it and all was well this year.
