If there is oil in it, its probably a failed oil cooler. If its fuel (that wouldn't necessarily make it a dark color), that would point to failed injector cups. If its dark in color, I would guess oil.

I'm having same issue on my 01 excursion. Dark oil, well mixed, no gobs of oil, and doesn't smell like diesel fuel.

2001 excursion 4x4, 4" Magnaflow SS exhaust, AEM Brute Force intake, 05 conversion, 6k HID's, after market tail lights, and thats it for now. More to come..
