I was very skeptical about comments of cleaner oil especially since I already had it ORMed and have experienced the state other diesels got their oil into.
I don't know what to make of the oil comments. I've been running SEGR since about 30K and have had the GDE tune for about 10K. Neither made any difference in how dark the oil is. It's pitch black before it's warm and has been like this since the Jeep was new. I've had oil analysis done and they tell me to run it longer (I don't). It is really, really black and stains anything it touches.
This is interesting to me. BEFORE my GDE Eco tune my oil was black immediately, and you're right, it used to stain my hands black for a few days when I tried to change it. It was so bad that I wore latex gloves.
After the tune, (50k ago?) my oil stays much lighter in color and my hands don't stain when I change the oil. I don't wear gloves anymore. I sort of forgot that it used to stain my hands real bad until I read this. I wonder if your EGR is closed correctly.
For the record, I have no idea what was staining my hands. I guess I'm going to say the extra soot.
