In very cold subfreezing temperatures my own personal opinion is to allow extra time for the engine and transmission oils to circulate freely. Perhaps a couple of minutes. Then ease into gear and creep along for 5-minutes if conditions allow it, then slowly increase speed. If I lived in Walrus Tusk NWT next to a freeway on-ramp I would modify this personal recipe.
