Does anti-freeze brand matter?

The time has come to winterize the plumbing again. On the assumption that propylene glycol is the way to go (vs ethanol or blowing out), does brand matter? What does nüCamp recommend?

Yes.  See attached thread.

I saw three brands (Walmart, Camco, HomeDepot) mentioned with no preferences. My take on the question is, then, brand doesn't matter but the contents do. As long as it's propylene glycol you're covered. Vodka, while potable, lacks temperature range.

I'll also include that it you live in a normal winter climate or warmer winter climate the standard -50 antifreeze is fine.  If you live in an very cold climate like I do then I'd use -100.  I use the Prestone -100.

Point taken. Even 30 years in the Sierra Nevada we never needed Prestone's -100. Stay warm.
