How long can a car stay in garage if temps drop below freezing

would “change freezing point” be better terminology?

would you agree even Water Wetter would lower the freezing point a little? So would pouring in salt, bottle of beer, pasta sauce, etc... ?
Yes, I agree with you...and sorry, I'm not try to be a turd. I actually am a Chemist by trade (Analytical Chemist), and I get a little nit picky on wording...because.....well, I can't help it, its what I do.:)

Carry on.
