There is no such thing as magic oil.
Maybe it comes across wrong to say "I would use " or "MB knows better" etc.
But choosing 15w over 0w on a newer MB was why I noticed this thread. Some say great, some like me hmmm. Just opinions we bother to take time to express.
BTW I plan 5K or less, 12-18 month oil and filter changes,with the factory stuff, not respecting the MB engineers oil gadget, even if they know it all. I know how wife drives though, they don't. Says 5k on clock, but add 10k worth of idling at lights. I know it is supposed to take that in account, but I think I know better.
