Motorcraft 10W30, 5W40, Rotella or Mobil 1 for 6.7

2011 F350 6.7. 10W 30 Motorcraft is listed oil for 20*-100*, 5W 40 for towing 1000 miles or severe duty-also Motorcraft. I went with the 5W 40 for this first change.
Next up is coolant flush, differential fluid and front wheel bearing repack, then fuel filters, air filter (maybe), trans filter and a possible serpentine kit with tensioner and idler changed along with new belt.
