Just bought a used 2004 Dodge Ram 2500 with a Cummins 5.9 Diesel engine (24-valve, I think). It has a little over 100,000 miles on it and is in excellant mechanical condition.
My question is... what type of oil do you guys use in these engines and please give any other service recommendations that you have to offer on this truck.
It has to last me a long time.
Thanks for your help.
I had a 2005 before. I ran Delo 15-40. Never any issues on oil. I had a Manual trans and every other year changed the gear oil with Amsoil. Same with the rear diff. I would also put external fuel filters on it to keep those injectors clean. Should be god to go.
