Supertech (Wal-Mart) RV Anti-Freeze
Wow, did I just dodge a bullet. I noticed that an unopened bottle of this crap was frozen almost solid at 0° F. I checked both RV's I'm storing and the drains were frozen solid. I thawed it out and checked it with my spectrometer, and it tested at 12% propylene glycol. The minimum concentration that will yield the protection claimed is 35%. This stuff is good to about 15° F.
I checked both RV's that I'm storing, and the drains were frozen solid. I added a few ounces of propylene glycol full strength to each and fired up the furnaces. They all opened up, and are now protected. If I had not done that, they would have burst.
It was real fun, as we had a cold front rolling in, -7° with -20° wind chill as I was scrounging up and installing propane tanks.
Fortunately, after I flushed the water lines with this crap, I blew them clear with compressed air, so no worries there.
If you used this stuff, check it out. You may be in line for some heart breaking damage.

I never buy anything with the SuperTech brand name. Just one reason stated above. Besides why would you drive a $70,000 truck and use .99 a quart oil in it.

I've had very good luck with SuperTech synthetic oils in my small engines and gas automobiles.
I tested some Peak RV anti-freeze and it wasn't much better, 16%. I'll use it in the water system and blow it out with air as much as possible. for the traps I'll use safety-freeze 33%.

Side trail. A long time age I rented a UHaul truck. Checked the oil at the rental place and nothing was on the dipstick. Guy said they don't put oil in. I wrote that on the papers and he signed next to it. He also put on there that eh would reimburse me for oil. We stopped at a little store. Found some really cheap oil. Label said using this oil will void all mfg warranties. In it went
