Prestone rv pink antifreeze

I just bought 12 gal of Walmart branded Super Tech at $2.59 a gal. We pump it throughout the house water lines so we can leave the heat off. Been doing it for years and it works fine. I'd have no concerns using it in the RV if we didn't take it to Arizona for the winter.

It's just a matter of reading the label, which will show the contents. The other thing to watch for is what they claim for freeze point - none are pure PG, they have added water. How much depends on the area of the country and price.

Last spring I picked up 8 gallons of sta bil at Walmart for a $1 a gallon.

I use the Super Tech -50 degree stuff for $2.58 Our Walmart also has the -75 degree stuff for $1 more. Since I've never encountered -50 in Western NY I'm not spending the extra money.

For comparison, here's the pertinent part of the Prestone MSDS:

Note that propylene glycol and dipotassium phosphate are both common food additives used in many products.

There are times to be brand conscious. RV antifreeze isn’t one of them.

Here's the MSDS in part for at least some of the Super Tech RV & Marine antifreeze sold by Walmart. Check the labels before buying...

If you buy a product because of personal preference, . . . that's fine.

Are you putting this antifreeze in your radiator/cooling system or in your plumbing system?

If it goes in your cooling system, follow the vehicle manufacturers recommendations. If it goes down the drain to winterize your plumbing, do you really think that ethyl alcohol will damage the seals? Think about all the other "stuff" that goes down there. You might want to verify your "seal and rubber" information with credible sources. Taking/passing a college level course in general chemistry might be a good start.

In the U.S., there are over 50 antifreeze manufacturers and tens of thousands of retailers who sell various brands. IMO, if you can't find one that fits your particular preference, that's because you haven't looked very hard.

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

Mine does too, but i did not see a list of ingredients..

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.

X2. I've been using Super Tech antifreeze in our 96 Southwind for almost 12 years.
No problems.
Maybe we're just lucky?
