With the impending arctic cold air coming, I am wondering how cold would be too cold to cold start my E39 M5 running Liqui-Moly 10W-60? I am contemplating switching to Mobil 1 0W-40 that I run in the non-M BMWs for the winter, but given that we'll be back to the 70s within a week, not sure the change is justified for such a short duration event.
