FWIW I use to run regular Mobil 1 in my duratec and while my samples from blackstone at the time were all good and within typical spec, when I switched to Pennzoil ultra platinum my wear levels in copper and iron decreased noticeably in every sample since.
Not trying to make a case for Pennzoil but in my instance it would seem Pennzoil is superior to Mobil. At least ultra platinum vs Mobil 1.
Which Mobil 1?
