I'm new to this diesel thing. Never had one before. Although our T/V is a Ford our dealer recomended that I use 15-40 Motorcraft Oil for Diesel motors. Don't know that the brand would make any difference but I believe this is a partial synthetic oil. I wish I had the history on my truck but I don't have. It is purring like a kitten right now and it has 311k+ miles on it. Don't have any reservations about taking off somewhere on a long trip at this point.

15W-40 is the correct oil. I use Motorcraft oil. I used to use Rotella but decided to now have my oil changes done at Ford. I don't believe that this oil is a partial synthetic oil. I wonder where that thought came from.
