"a friend that owns a garage ... told me that a customer told him that he his brother, a janitor at a well known oil company was cleaning the men's room when he heard engineers talking about the Oil Change Interval..."
?!?!?!? 
Well that sounds just about as good as hearing it from the mouth of God.

which is why I asked if these "engineers" were discussing conventional or synthetic

Then you are fast and cheap. I get the K&N filter for $15 because of the nut that allows me to unscrew it easier and with that kind of oil is $32 around here. I can't even get that sort of time for my MBs which doesn't require the car to be lifted. With those, I have a cartridge style filter and a wrench takes the cap off, pull out cartridge and replace and screw it back on. After that, I have to fill it, run for a minute and let it settle down, check level and then wipe off any spills with brake cleaner. Oil removal is done by topside which sucks oil oil out but you spend time to get the air compressor up to pressure. Dump oil into cans and bring it to Autozone or something.
To the OP - alkim's early answer is still the best - do an oil & filter change - drive the car somewhere around 5,000 mi, drain the oil - but after about a quart drains out - get a sample, and send it off for a real oil analysis. That will provide a fact based answer about the oil's ability to keep lubricating. Let that be your guide.

Just out of curiosity - you say that you use the K&N filters, and that used to be my brand of choice, but all of a sudden the reviews of them went from nearly all positive to a whole bunch of negatives (about 12 - 18 months ago). Seems that K&N went from having the filters made by Champion Labs to having them made in Mexico, and a number of people have been reporting problems (leaking at spot welds, bad threads etc.) on a "major retailer" website. I still have a few Made in the USA K&N's - but I've gone to buying Mobil 1 filters for a while (also made by Champion Labs). Just wondering if you have had any problems or even seen a difference with recent production K&N filters (country of origin is Ink Jet printed on the filter itself). I also really like that 1" hex on the filter bottom.
Well, you try looking at what the size of a K&N 1995 filter for a Ford Excursion is and realize how hard you have to crank it or it leaks and you will be glad for the nut. In the winter, when I took it to Wal-Mart, they broke the strap wrench they used, got another one, broke it and finally, I went home, got my own heavy duty one and it worked. Now with the hex nut, it makes life easier in the winter when I don't want to lay on the ground trying to crank off the oil filter. Has it had any issues? Nope. Only when you don't turn it hard enough then it leaks but that is common with the Powerstroke in 7.3L.

I run M1 Full-Syn High Mileage 10W-30. I change the oil once per year, usually in spring when i get it out of storage. I dont worry about the drain interval, since i only put about 1k on the car per year. The HM has more zinc and phosporus, which is better for our older cars. And i only use AC filters.

No less than once a year and no less than 5k miles. A GM filter or Wix, Castrol full synth SN+ 5w/30. I think I’ll be ok with this ritual
