First timer from New Mexico. Just bought 2007 Chevy Silverado 2500HD, 4x4, 6.6 LMM, Allison. 89K miles, runs great. My first Diesel, dealer said they changed oil, checked it after 100 miles and already dirty. Should I flush? I'm calling dealer tomorrow to verify oil change and type (synthetic).

What exactly in the oil is "dirty" ? Oil is dirty to begin with haha, as soon as you crank up a diesel, the oil will get "dirty". Its natural. Milky or dis-colored or smelling different is unusual though.... Oh welcome to the forum !!!!

Can't claim that one. I am running AMSOIL 15W-40 Diesel and Marine Oil and it stays dirty. Even after I flush the motor, and I do every oil change.
