Which engine oil do you use in your CTD?
I use Valvoline Premium Blue. Cummins ran a series of tests with this oil and had very good results.

Rotella is a pretty good oil. My grandfather runs it in his class 8 trucks and at least 3 of them have over a million miles and several others have close to a million. I bought Amsoil for my truck and I'm waiting for the Wix filters to come in so I can change oil, tranny fluid, fuel filter, and rear end oil at the same time since I just recently bought the truck and it has 100k miles on it.
I use the Valvoline Premium Blue (not on the poll list). It has the Cummins logo on the jug. Used a Mopar oil filter. Can you believe the local Dodge dealer sells them for $8. Pick up 3.
I use shell rotella, every 5k miles. First person to say they use whatever is cheapest at walmart....let me konw where you live so I can get a few of the guys together and we can "discuss" your choices.
