Pure antifreeze (ethylene glycol) will freeze at about 0 to -5 deg. F. Years ago, I actually had it happen (left jug outside one very cold night.)haven’t seen anti freeze freeze yet. Gonna call BS on this one
Back when I was growing up, it got so cold at night that the fire in our fireplace would freeze. If we tried to throw another log on, the fire would shatter and send shards across our living room floor. We'd have to sweep them up before they thawed and burned our house down.
50:50 for -34F
60:40 for -60F
70:30 for -84F
Pure antifreeze (ethylene glycol) will freeze at about 0 to -5 deg. F. Years ago, I actually had it happen (left jug outside one very cold night.)I know if you pee at -40F it freezes before it hits the ground. Makes a tinkle tinkle noise as it hits the ground.
At extreme low temps it can gel, like diesel fuel does. But if it’s low enough to gel antifreeze, ain’t nothin gonna work.
