Costco sells, on sale, occasionally, 4 jugs of their brand for $8.50, which is -45 rated. I am unsure if it is the best I have ever used, but so far so good as far as freezing goes. Keep your eyes out for it and stock up when you see it.
I never thought to check Costco, we're making our weekly trip there tomorrow so I'll see what they've got! This afternoon I also picked up two jugs of -35C rated stuff from our Walmart here for $2.88.
When I saw how cheap this stuff was in Niagara Falls I couldn't resist a bargain like that!
I topped up both of our winter driven cars with it today but both cars had at least 75% of the -49C stuff in there as well. So based on the posts I'm seeing here, I think I'll save this -25 stuff for the early spring when we won't see such brutally cold temps.
