The only unusual finding in this sample was sodium. 39 ppm is not enough to call it antifreeze, but it's not present in Motorcraft oil. Maybe you used an oil in the past that contained sodium and it's still washing out. Wear looks good, so this doesn't really look like an antifreeze problem. If it is, it's a new problem and can be contained for now with short oil changes. No fuel or moisture was present in this sample, and the air and oil filters are working well for you. Try 7000 miles for next oil change (3500 miles is average) and check back to keep an eye on sodium.
I know the make-up oil skews things a bit, but hey, my engine did not blow up with this thin oil!
This vehicle has a pretty easy life with a 25mi commute each way to work. However, I pulled a trailer a couple times. Once I pulled a trailer up to Tahoe, during our heat wave last summer. It was 107F-112F while I was flooring it up the mountain. Car did not overheat, but I am sure the oil got pretty hot.
The sodium is probably left over from the previous oil which was Mobil 7500.
Oil filter was Purolator Premium Plus.
