OW-40 is also approved but the one time I tried it in my OM-617 I did not like it. Engine was noticably more "clattery". Would probably be the best choice for really extreme cold, though. When I'm able to get it, I run 15W-50 year round, or the "Turbo Truck" 5W-40 (Delvac-1), though that is harder to find here. I fall back to conventional Delo-400 if I can't find anything else.
