that's what i ve used in the 03 3500 cummins ram. hard to find and very costly. but the factory rec service is 7,500 miles so i pay for the best oil i can get. btw wait till you service the auto transmision, power steering, and transfer case. it takes mopar transfluid and so far it's dealer only syn. atf.
good luck!
