It's now the 21st century and this discussion is about synthetic oil.
Here's some data:
I checked the "cold pour point" specification for various grades of Mobil 1 on their website.
They were ALL THE SAME, same for 15W-50 being about 15 degrees higher. That made it minus 40.
No, just run year around the ONE version of Mobil 1 that meets Mercedes specifications and is NOT designed for diesels: 0W-40 European Formula.
