For a 6.0 PSD:

What oil/filter do you use and why? Any oil additives?

What transmission fluid/filter do you use (Torqshift 5-speed with O/D)and why?

What fuel filter/water separator do you use and why? Any fuel additives?

What air filter do you use and why?

What differential fluids do you use and why?

I have noticed that many of the factory parts are expensive ($28 for an oil filter!). Are there better alternatives, or am I better off with all factory filters/fluids? Thanks for sharing your experience...

The ONLY fluid to use is MERCON SP. This trans is EXTREMELY sensitive to fluids, and that is the only type rated for use in this trans.
