The mix may not the same everywhere. I can tell you this.....and I just learned this last week. Wiper fluid comes in different degrees. Our normal stuff goes down to like 22. Then there is some we carry less of that goes down to 0. Then the stuff we don't stock goes down to -32. The reason I found this out is because one of our biggest accounts is a guy who specializes in OTR truck and diesel repair. Some of his customers go up north, including Canada and Alaska. He just askedlast week if we could get some wiper fluid that would go further down and we looked and lo and behold we could.
Whether this holds true for antifreeze, I don't know but I wouldn't be surprised.
