oil 7,500 - 10,000 miles or one year. I push mine farther on my 2010 changing it monthly. I do oil analyzis and have a by-pass filter. Typically change between 16k and 20k miles.
Fuel filters, I have heard from the guys that drive these newer 2011+ GM diesel trucks filter will go 50,000 miles+. Or just change it once a year. If the filter ever does get clogged the truck will go into limp mode. Not fun pulling a trailer.
NEW Diesel Exhaust Fluid. This can vary by how hard the engine works. I believe the typical range is 3500 to just over 4000 miles before truck wants more. Its important to not let it run low. The truck will limit its speed. The best place to buy is pumps at truckstops.
