Home Hardware sells pure propylene glycol. Search for Cryo-Tek concentrated
18.9 liters ( 5 US gallons ) is $135.
It may be that glycerin based antifreeze is the best choice for winterizing an
though other than in sprinkler systems it has not caught on.

The plumbing antifreeze sold here is denatured ethyl alcohol (ethanol), which
is not great for rubber parts, but not as bad as methanol. As I noted in my
last post, there is sometimes available a "premium" version plumbing
antifreeze, which does contain at least some propylene glycol, but it contains
ethanol as well. I went to some lengths to try and get a product that was based
solely on propylene glycol and was not successful here in Ontario, and I could
find nothing online anywhere in Canada, except as I also noted previously, the
grossly over priced speed shop engine stuff. Either you have had good luck with
ethanol, or the plumbing antifreeze that is available where you live is
different. I wasn't so worried about the impeller in the engine as I am about
all the rubber parts in the head. It is both a PITA and expensive to rebuild.
