I must have a motor oil fetish of some sort. I guess I am just really interested in what are good oils/filters.

This all started in the motorcycle world for me, when people said you don't need to buy $10/qt moto oil when $5/qt car oil will work just fine. This lead to a lot of argument, with little proof on either side.

FWIW...

Oil Filters put to a pressure drop test, I found this on the net:

I got to it from this guys site:

His theory is that more pressure drop equals more filtration, which is kinda pseudo-science, no?

Here is an article on using synthetic oil for longer than 3,000 miles. In the test, they used Mobil 1 for 18,000 miles in a 5.7L Camaro...

Modern BMW's tell the owner when to change the oil (which comes synthetic from the Factory) and this usually happens around the 12,000 mile mark so I am told.

Amsoil says 25,000 miles between oil changes, but you need to change the amsoil filter at half that or so.

I was planning to switch to Mobil 1 5w-30 in the next few days, and maybe even do the tranny with something synthetic. Any recommendations for a full synthetic tranny fluid? I was thinking either Royal Purple, Mobil 1, or Schaeffers 267 80w90 from "OilGuy" site.

There's Ford-designed fully synthetic tranny fluid that -- according to many -- works miracles with MTX-75. I've been pretty much going the same route as you -- bob's info, paradise garage tests, etc. Recently I've been looking into how transmission works, how to make its life easier, etc.

Opinions on Royal purple, Redline, Amsoil, etc. differ, but everybody who tried it, unanimously praises this Ford "Gold" fluid. Part number if XT-M5-QS, cost is over $15. (Don't get confused with mt-5-qs or whatever with the price under $4.00 -- that's not it).
I'm not sure if they were putting it into newer vehicles from the factory, but I doubt it. Wouldn't hurt to find out. According to what I found out, Ford developed some stuff that facilitates shifting in this tranny, and Redline or anything else that is recommended for MTX-75 contains the same exact stuff, only less of it. Also, Ford service bulletin tells all Ford dealers to top off or refill ALL TRANNYS with XT-M5-QS, after any work has been done to them. My guess, if it's just a top off, the owner most likely wouldn't even know it, and wonder how great his shifting became all of a sudden...
Based on all that, I've just picked up 2 qts from a dealer yesterday.

Sure looks like gold in mine.
I know it is in the wife's Escape.
It was a little low causing the coolant light to come on,
so I picked up a gallon from the Dealer...$13...IIRC.
