oil grades

My new 2016 Ford Power Stroke F 250 diesel recommends oil 5w-40 syn. oil for towing. I’ve been using 15w-40 Shell Rotella. What oil have you been using?
  • Been using 15W-40 Rotella since new (2006)

    Full Timed for first 7 yrs towing 14K 5th wheel weekly.

    I am anal about oil changes.
    Change oil/oil filter every 5000 miles.......fuel filter every 10K and air filter when 'dirty'
