The new CJ oils
Shell Rotella Triple T 15w40 8.77 TBN at $11/gal
Amsoil Premium Synthetic 5w40 7.61 TBN at $27/gal
Chevron Delo 400le 15w40 7.82 TBN at $13/gal
so these are what you consider bargains..... hmmm.... I'll pay a little more for a higher tbn, a load more of moly and other good stuff....

My last oil change I went from CI-4 to CJ-4 (Chevron Dello 400). I had an oil analysis done on the CI-4. Next oil change I will have another oil analysis done and compare the wear products present.
Diesel Power magazine published an article about a year ago and said the low sulfur blend CJ-4 Rotella had significantly less wear.
CJ-4 is backwards compatible with previous year models.

The TBN on the new CJ-4 valvoline premium oil is 10 , and the part number is the same for the new oil and the old CI-4 oil , the new will say CJ-4 and label face will be colored red instead of blue. I would check on Rotella and see what the TBN is and like Don says , if your changing the oil at 5 thousand miles, you will be alright.
The recommended oil change on the 6.7 truck engine is 15,000 miles , but they use a larger oil pan and bigger oil filter also.

TBN = total base number, which is a measurement of additive left in an oil. These additives are what protect your engine from all the byproducts of combustion. One of which is acidity which will eat away the insides of your crankcase if your oil isn't doing it's job properly.
The main thing I'm learning is the newer CJ oils just aren't anywhere near as potent as the CI blends. PERIOD. Numbers don't lie. Now honestly it doesn't matter a darn to me because I'm going to change my oil every 5000-6000 miles anyway because I'm running excessive horsepower...
But I like to know I'm protecting my expensive engine with the best oil. Those guys who like to run long oil change intervals are gonna have a harder time when these new oils don't have near enough of the good stuff to start with.

This contains a lot of info on the "new" CJ4 oil. What stood out to me was that yes the TBN starts lower, but it is more robust than in the CI oil (stays around longer).

I just did an oil change on my truck. I used a Stratapore 3894 and Chevron Delo 400 LE CJ-4 15w40. We'll see.
On a side note, where I bought the oil filter, they had cutaway filters on the shelf so you could see the guts of 'em. man that stratapore is one good filter!

For the last 2 years I've been using Mobil 1 synthetic 5-50. Anyone else using this or another synthetic? If so how often are you changing oil and filter? I find the difference in the winter to be unbelievable.

Summary: Oil
Solution:
Thanks for your Email message. You have contacted Cummins, Inc. at our Customer Assistance Center located in Columbus, Indiana. This is our worldwide headquarters and has been our home since Clessie Cummins founded the company February 3, 1919.
There are a lot of rumors about fuel and oil going about right now.
CJ-4 oil is required for the engines with aftertreatment exhaust systems. Other Cummins diesel engines can use either CJ-4 or CI-4 as long as the ULSD fuel is being used.
Vehicles using the older fuel (as in Mexico) should use CI-4 or if CJ-4 is the only oil available use it but cut the oil change interval in half.
Also we found an older FAQ style sheet that may be useful for you.
A new engine oil for 2007 is being introduced with a formulation that meets or exceeds the performance requirements of today's lubricants, while also providing protection for emissions control systems.
These new low-ash oils are identified as API CJ-4/CES 20081, and they meet Cummins Engineering Standards. The API CJ-4/CES 20081 oils are specifically formulated for improved wear protection, deposit and oil consumption control, soot-related viscosity control, prevention of viscosity loss from shearing, used oil low-temperature pumpability, and protection from thermal and oxidation breakdown when compared to previous API and CES performance categories.
Although the API CJ-4/CES 20081 oils were developed to be used in 2007 Turbo Diesel engines, they are also backwards-compatible for use in pre-2007 engines running on ULSD (Ultra-Low Sulfur Diesel) fuel. These oils are also compatible with LSDF (Low-Sulfur Diesel Fuel) in pre-2007 engines. In fact, if you are running LSDF in your pre-2007 Turbo Diesel, you can maintain the current oil drain intervals recommended for the API CJ-4/CES 20081 oils. (Consult your Owner's Manual for the appropriate oil schedule specific to your driving duty cycle.) Older oil formulations will still be available, as many oil manufacturers will continue to sell products meeting API CI-4/CES 20078 for use in engines/vehicles burning higher-sulfur fuel. These oils are acceptable for use in pre-2007 engines with no change to oil drain interval. However, the older oil is NOT recommended for use as the engine oil of choice, or as a top-off oil, in the 2007 Dodge Ram Turbo Diesel - regardless of fuel sulfur level. Only CJ-4/CES 20081 engine oil should be used in 2007 Dodge Ram Turbo Diesels.
For your 2006 Diesel you can safely use CJ-4 or CI-4 and the new ULSD fuel. These items are backwards compatable with our older products. They both meet strict standards for lubricity.

It seems to me that I person would get great results with some CJ-4 and a little more anti-wear additive if that floats your boat, something like Torco MPZ.

BUSBOY,
Are you sure that the Mobil 1, "5X50" is diesel-rated? I believe that they have a 5X40 (Mobil 1, Turbo Diesel Truck).
Make sure that the "5X50" is CI-4+ or CJ-4 rated.

retired chuck,
I believe that the 3894 is a standard cellulose filter media & the LF-16035 is the Stratopore filter. The Stratopore is more desireable (better filtering media).

Rowland, This is true. But everyone with an 89-07 truck can use the LF16035. IIRC the only difference between the 2 is the 16035 has a fluted end to make it easier for removal with an end cap wrench. http://www.genosgarage.com/prodinfo.asp?number=LF16035

Buffalo thanks for the comments, I was using a Mobil 0w50 that was cf-4 and did say for diesel use then about 2 years ago I tried to buy it again and they no longer made it. The auto parts store told me that the 5w50 replaced it and it was good for diesel use. I had tried at the time to contact Mobil but the wait times were too long so I just went with what the auto parts store told me. I should know better, I phoned Mobil today and this time waited for a "tech guy" he told me that it is approved for diesel but does NOT meet cf-4 specs. So I am now about to change oil immediately this time with a PetroCan Duron 5W40 synthetic that meets CI-4. Luckily no engine damage. Thanks again for getting my attention.
