RV antifreeze?

lkc001

What brand of RV antifreeze do you use?  I am going to do the antifreeze method of winterizing.  I have read some negative reviews of the Walmart brand of the pink stuff "Super Tech RV & Marine"--anyone used this brand?  Would like to find a propylene glycol (no alcohol) based brand, or are all RV antifreeze the propylene glycol.  Camco brand, of course, appears to be the most expensive.  Are they all the same?

What did the negative reviews say? Does it freeze when it's not supposed to?

I just grab whatever pink stuff is handy when I'm thinking of it and everything seems just fine come spring. But I like livin' dangerously!  ;-)

Pink stuff is NOT all the same. You can have alcohol based, PROPYLENE GLYCOL or a mixture. Professional RV places recommend pure PROPYLENE GLYCOL ONLY as alcohol tends to dry plastics and rubber out and also can leave bad taste even after flushing.

Of course the "good" stuff is more expensive as most things in life!

As far as brands, I need to look at what I got from my local RV place. I had to ask for it, the stuff out front on the shelf was a blend! I have heard that Rain-x makes it ,but be sure it isn't a washer fluid!!

Most brands are rated by burst temp, NOT freezing temp which is typically much warmer. The burst on most is -50F, BUT some brands also sell burst of -100F, of course for more money.

I went with South/Win from Home Depot. Propolyne glycol based and easiest for me to quickly get my hands on.

@ScottG several comments said they still had something crack over winter.  That is concerning.

@N7SHG_Ham would like to know the name of the antifreeze you use.  Thanks for the article.

I think the brand I used is Winter Safe, BUT I will double check that later today, my friend just sent me a photo of a jug he bought at same place on my recommendation, I will attach it, BUT it doesn't clearly show the actual
brand.
