standard 15-40 dino il is fine.
a lot of people like the rotella t6 synthetic. thats what im gonna try
the next time i change my oil.
if its cold where you live you can use 5-40 synthetic.
i use wix filters (napa gold), a lot of guys use motorcraft ones.
the fuel filter is under the powerstroke cover if its not broke off. right on top of the motor.
i change it between 7,500-10k miles.
no need to drain it unless you get the water in fuel light.
and as far as the diff cover goes, thats your preference.
i would do the usual maintennce on everything, trans, transfer case, differentials and so on.
the rear end takes 75w-140 synthetic only. with limited slip added unless the gear oil already has it added.
i went with valvoline full synthetic with the limited slip additive already in it.
it takes 4-5 quarts i cant remember.
