Whatever is on sale Every 4s engine I own runs on sale priced Dino 15-40. Except the wet clutch bikes get Rotella T6. Well, and I have put the spec 0w40 in the new car for the first couple oil changes , but it’s not necessary, just my current preference.
Maint interval is more important than brand of oil.
06 Cummins will live a healthy life on pretty much anything that says 15-40 on the jug.
