I use Mobil 1 High Mileage 10 W 30 and do oil testing with Blackstone labs, so far my numbers are excellent even when I went 8000 between changes. For what is worth my zinc levels were 870ppm. I am not seeing any noticeable wear or problems based on the results. I use about a quart in 4000 miles if I go that long between changes. Seems to like the Mobil 1 is OK.
