The run of this 5W grade oil was 1,059 miles from about 28,000 to 29,000 miles on the truck. According to Red Line the HTHS = 1.58. The J300 has a minimum kinematic viscosity requirement but no HTHS requirement for this grade. The HTHS for an 8 grade oil is 1.7.
Half high speed highway and half city driving. The engine takes 6 qts of oil and I would have needed to add a quart if I was going to continue using this oil. Normally with a 20 or 30 grade oil this engine uses no oil between changes.
At around 25,000 miles the air filter was replaced. Around 20,000 miles everything timing chains related was replaced, it was making a lot of noise just after start up especially. It was a known issue. All new seals to complete the work.
Previous oil changes were at around 6,000 mile intervals +/-, always with either 20 or 30 grade Motorcraft oil.

Upcoming 0W5 Grade Red Line Oil Experiment- 2019 Lincoln Navigator 4WD 3.5L V6 Twin Turbo
Engine: This Black Label version of the Navigator has a 3.5L, 450-hp twin-turbo V-6 pushing an over 3 ton barn door through the wind. It has 9k towing capacity and specs a 5W30 motor oil. It is mated to a 10-speed automatic transmission. The package gets you to 60 MPH in 5.4 seconds. Correct me...

I will provide the comments from the testing labs later.
My guess is that the bearings are aluminum, tin and silicon with a copper base. The high copper is likely mostly corrosive rather than wear.
Water is high as the oil probably did not get very hot to help burn it off. Remember the products of combustion are about half CO2 and half H2O. Humidity is always elevated here and we know that it is an independent factor for wear, it is now controlled on ASTM engine tests.
Regarding the small particles seen on the oil filter. I do not know how much is metal, what type or if some of the particles are gasket material. The Motorcraft oil filter is rated at 50 percent capture of 20 micron particles. 20 microns is the limit we can see with the naked eye. The blot filter paper test was unrevealing and there were no particles even under magnification.
Occasionally the oil idiot light would blink when using Motorcraft 0W20 in my wifes Lamborghini when very hot. I forgot what the pressure guage showed but remember it was unremarkable. I wondered if the light would show up on this truck. It never lit up, if that tells us anything.
One of the purposes of this test run is to compare different labs results on the same oil sample. You may want to comment on this aspect as well as my insanity.
