FWIW, I've been using Mobil1 10-W30 for years both in the 4.4i and the Tundra Gen-1 (200k). I just finished chain guides and seals job on the 4.4i and the motor runs clean and well. Wear on the chain guides was minimal the internals were very clean. Both motors run quietly and trouble free but I change oil every 5k - 7k, intervals which are a bit short by modern standards. Still, I feel the mobil1 works well. Nevertheless, I think most brand oils will do the job well enough given the right grade and not overly long intervals between changes.

On the other hand, in my E70 35d I use only the oil from BMW itself, as diesels are pickier and it is priced within the ball park if bought as a kit.
