I've run Mobil [1] for over 25 yrs in ALL my vehicles (0w-40 in the M62 X5, almost 200k miles now).

No wear issues and only 1 leak (VCGs on the M62).

Pic from the VCG gasket change at almost 190k miles, manufacturing grind marks still visible on the cam lobes (pic date is actually fall 2014, battery died on camera, didn't reset date pre-photo).....
