Prestone rv pink antifreeze

Walmart by me has StaBil brand, no alcohol. Plenty of warnings on the container not to use it as a fuel stabilizer though!

Interesting...
I just went out to the garage and looked at the Camco RV antifreeze I have left.
Sure enough, contains ethyl alcohol (denatured alcohol).
Considering how long I have been using the stuff, all my drain valves and seals should be rotted away by now.
No problems.
Oh, well, too late to change now, I'll just keep on doing things as I have been all these years.
I think I have just enough to do the job one more time.

You are correct, but I wouldn't limit my choices to just one brand. Just look at the ingredients and pass on those with ethanol or alcohol, or whatever they choose to call it. I bought a case at Home Depot last year that was a brand not often seen. Check Lowe's as well.

I've been using the Walmart SuperTech RV antifreeze. It's good to about -40. I blow the lines and put pink stuff in the traps.
And it's fairly cheap. It doesn't get that cold in PA.
I don't remember seeing Prestone at Walmart around here.

Difference between Prestone, and WalMart brands. Usually about $2.00

I am not ready to buy any yet, but I noticed that our local Walmart had a huge pallet of their "House Brand" RV non-toxic anti freeze on display yesterday.
Come to think of it, I need to check, I might have enough out in the garage to do the job. It doesn't take much to protect the drain traps and the toilet valve.
IMO, the "House Brand" does just as good a job as the Prestone, at a lower price per gallon.

Why Prestone? Is there something special about that brand, other than personal preference?

FYI- I have used Walmart house brand for years, even down to -40C without issue.

Why buy Prestone? I have used the cheapest off brands with the same results. Buy what you can find on sale or cheap.
