VPB ---- Recommended by Cummins
Mobil-D ---- Great Oil
Shell Rotella ------ Another Great Oil

** With the fuel contamination issues the 6.7 has I would be doing cheaper oil SHELL/M-D and changing every 5,000 miles. It all depends on your local prices.

Can't go wrong with Rotella! Change it every 5,000.

Rotella is what the dealership uses in my truck.
