36mm socket on the oil filter cap. Motorcraft filters only. If you still have the DPF intact and the truck is regenerating, then your oil is how it is suppose to be. There will be some fuel in it from the regen process. The oil will be pitch black in an EGR diesel before 1k miles on the oil change. That is how it is.
Make sure you do not make the same mistake as the dealer. Those plastic caps are NOT designed to be that tight. I believe the torque spec is stamped on the cap itself.
The dealer tech was probably someone who didn't know what they were doing and figured too much is better than too little. If in doubt, find a torque wrench!
