Ive been doing a lot of searching recently on best oil for the 6.4, but coming up with a lot of dated discussions. Now that these trucks have been on the road a while longer I figured I'd start a current oil thread.
I have been running Rotella T6 5w40 for the past year and have no complaints. Is there anything better? What are you running?
