Well I dropped the factory fill engine oil and rear differential lube in the 2011 Mustang GT 5.0 with 1062.5 miles.
The oil was run through a fine stainless mesh into a clean pan that caught absolutely nothing. I ran it back through a white cloth and all that I got was some very fine gray "powder" that might have been from the ring seating.
The differential lube was essentially the same other than the fact that most of the gray powder was on the the magnetic plug.
The Factory FOMOCO Filter appeared to be a Champion PH500 although Im not certain its internally the same. The replacement Motorcraft FL500S comes with an 8-psi Bypass Spring and Im thinking the standard PH500 uses a heavier spring. The FOMOCO Filter is a little longer than the FL500S.
I refilled with Motorcraft 5W-20 SB and used the MC FL500S Filter. It took exactly 8 Qt (Engine appears to fully drain) and the Filter mounts on a 45-Degree Angle. I pre-filled as much as I could without it running out while installing. I did not get any indication of low oil pressure on restart. The inlet is directly over the timing chain tunnel so the oil goes directly to the pan without having to drain through the head. Pulled the dipstick and allowed 5 minutes for dipstick tube to drain to make sure I got a clean reading.
PS After seeing this oil and rear diff lube I think Im finally ready to leave the early change camp.
