An infrequent hit of -20 F isn't too bad. It's not like we get -40 from the first day of winter to the last day, either, and we can have some nice winter weather. But, we can be hit with a very nasty and prolonged cold spell on occasion. And, one had best be ready for it. If a stretch of -35 to -40 weather hits, and one doesn't have a semi-sensible oil, and a reasonable battery, or some other nice-to-have accommodations to compensate for other issues, one can be in serious trouble, with tow truck waits being 24 hours or more and taxi waits being two or more hours.
So, when -40 does hit, I prefer not to be licorice-sticking a distributor shaft or having a battery give up the ghost for good.
