Yes, agree with above post. Also of note, my 2002 Cummins 5.9L would keep oil clean for a long time too. It's all related to emissions garbage.
My '03 Cummins was the first year of the new 305/555 HPCR engines. When new the oil would stay honey colored till around 3000-3500 miles depending on how hard it was worked unlike a '01 and a '96 Cummins I had in other trucks. Those old engines got black in a hurry.
The '03 has over 255k miles now and I still use the 7500/15000 mile oil change schedule from Cummins but losses that honey color at around 200 miles now.
I noticed when Cummins came out with the '04.5 325/600 engine with the 3rd injection event, some folks complained of their oil turning black quicker.
