It’s half sarcastic
WCW say 1 litre per 650l tank. Intriguing.
What a load of rubbish one ltr will not stop 650 ltr from freezing you put 2:5 ltr of antifreeze in a cars cooling system and that only holds around 10-15 ltr some people are so gullible and wcw shouldn’t be giving out false info either
Perhaps the strength is less with car antifreeze, not sure but it think antifreeze doesn’t contain isopropanol. I’ve never been one to buy snake oil products, but if this did genuinely help keep frozen hoses away, then why not. As said though, I’m not going to be the first to try it
Spruce, to me, I’m not worried about the tank freezing (tank always freezes from top down so completely irrelevant to me), but I did wonder if it would help keep the hose from freezing up if not using a hot system.... that’s the only advantage I can see, and, if it worked, it’d be a good product. My guess is, it wouldn’t work!
