I used to be the "pink stuff" guy as well, but the past 3 years, I've went solely with air and then pouring a quart of antifreeze down each sink/tub trap. Works for me ...
Don't forget to put pink antifreeze down the washer drain and open the supply valves located there when purging the system with air only.
I do this and all is good every year.
