I love Mobil 1 oil, so I won't get into the brand argument. I use either the 0w-40 or 5w-40 period. You can't always find the zero....but 5w seems to always be on someone's shelf... I would think any name brand synthetic in those numbers would be fine. But, Mobil 1 has been a proven winner in all my cars since the early 80's and I am staying with it....
