Oil & Fuel 50 hour service oil change

That would have been my choice if Wal-Mart had it. But I also started thinking that I will be changing my oil every 50 hours, which equals about once a year for me. Not sure if I will benefit from synthetic.

There's a Mobil 1 for diesels, which is what I run in my F350 diesel, and will use in my DK45S.

Can't go wrong with Mobil 1 Turbo Diesel Truck oil or Mobil Delvac (more geared to the heavy truck market).
