I'm wondering what's a good oil for my Mercedes C36, I've been using Mobil 1 15W50 for awhile and want to know if changing to Mobil 1 0W40 would be better? I live in Vancouver, BC, not a really cold area. Thanks
Reason of using 15W50 is because the 0W40 doesn't exist when I first own the car and no retail store carry them in Vancouver. And I just found out that's one place to order it.
