Premium Blue Full Synthetic 5w40 from Valvoline is the RECOMMENDED and preferred oil for this motor as it was designed by cummins and valvoline just for cummins engines. We switched our shop D-Max to this oil and it was an improvement across the board from economy to performance.

Well I had some service done on my front end and they said that Rotella is the way to go, but I really like AMSOIL.
