For short drain intervals, I'm comfortable advising to stay with the 9070 short filters. If you're doing approx 3000mile drains, you're not going to risk plugging even the short filter that quickly...and save a few $$$, I think the 9000's are about $20 more but I haven't bought a short one in many years so it may not be that much.

So are you just going to regurgitate some verbal diarrhea or personal opinion, or are you going to substantiate that claim with something of substance?

Lucas is zero additive refined oil base stock. It is used as a viscosity enhancer that then dilutes your oils additive package. I agree with Rawze, and do not use or recommend it.

Rotella is a high detergent content oil, which is why an engine with sufficient wear consumes it at higher rates than it's competitors.
However saying that it does as much good as Lucas is unsubstantiated. This is supported by this http://www.motoroiltests.com/diesel-oil-...E3FzutfOrU oil study. Number 1 & 2 are high priced 15/40 synthetics, #3 is a synthetic 5/40 which is specifically recommended to avoid viscosities of less than 15/40 by Cummins for use in any twin cam engine (871 or prior, which the OP stated '06). So that brings us to 4, 5, & 6. Four is Chevron Delo 400 15/40, five is Mobil Delvac 15/40, and 6 is "new" Rotella 15/40 followed by seven "old" Rotella 15/40.
Rawze states that ISX's need lots of zinc, and Rotella exceeds Mobil Delvac in zinc levels, so IMHO, that makes Rotella ranked 2 & 3, because I cannot justify the high cost of synthetics without extended drain intervals. Rawze has educated me on the inadvisability of that practice. Rawze has forgotten more about oil & additive packages than I ever intend to learn, so I'll happily defer to his recommendations and save myself the time investment to learn what he already shares.
Since the purpose of my post as to assist with the possible soot contamination buildup of this particular OP's issue, and Rotella has the highest detergent content of 4 through 7, this actually makes it not only a good recommendation, but the best recommendation supported by testing and knowledge.

I am human, and I am completely capable of being wrong. Prove to me I'm wrong, and I'll be happy to have learned something and gladly change my recommendation.

Speaking of LUCAS :) I never used lucas since i owned this truck and at all i do not recommend using it.
