You can thank ultra low sulfur fuel for that.

Whether it's a Cummins, International (6.9 and 7.3 idi turbo & non-turbo, 7.3 di, 6.0), Isuzu, Detroit, Cat, JohnDeere, VW/Audi, ect. that I've owned or work on, the oil ends up black. It may take a little longer nowadays for some thanks to ultra low sulfur. Alot of the DI diesels, even after oil is drained, still have a few quarts of old black oil in the high pressure system so upon startup it mixes with new oil turning it black.
Your Kenworth holds probably as many as 4 times as much oil so of course it will take longer to appear black. Also if you're running a by-pass filter it will help.
As a side note, if the oil wasn't black I'd be more concerned because it's job, among others, is to carry contamination to the filter(s).
To wrap it up it makes no difference EGR or not and black diesel oil is no indication of a problem, it's a way of a diesel's life.

How many gallons of oil does that Cat engine take at oil change?

Don't follow Ford's schedule for cleaning the egr, I do mine every oil change and replace the O rings and gasket every other time.

Sulfur is one of the contaminants of oil via piston ring blowby during combustion.
Majority of the engines I listed above do not have EGR systems at all and always had black oil. EGR systems cycle and sample exhaust back into the intake only when certain parameters are meant. They are more off then on. They are not what dirties oil. It's been happening since the start.

Sorry 05 crew I didn't get your whole post before I replied. No bypass on the kW, I won't run synthetic in semi so no reason to, dirty oil to me is a sign of a poorly running/tuned engine, egr makes oil dirtier, I didn't think anyone would disagree with that. I got writers cramp.
