Last January I took my "d" up to central Quebec (about 4 hours north of Montreal).When I arrived in late afternoon it was -10F (sorry,don't know celsius).I made it a point to fill up at a local Shell station in anticipation of a *cold* night.Thirteen hours later,at 7AM,it started like a champ at -31F.For the first 30 minutes it felt,and sounded,like a Mack truck but after that it ran like a top.Of course by then the temperature had soared to -25F.
These things are *amazing* in cold weather.
