Call me contrarian but I don't see the value in testing engine oil.
If something is going wrong, you will more than have other symptoms that will present themselves. Before you shoot the arrows, let me just say that in a previous life, we performed oil analysis on jet engines and gear boxes. Naturally, you don't want these items prematurely failing at 30000 ft or the middle of no where. This was done at frequent intervals, 10 hours after engine or gear box change and then every 50 or 100 hours (can't remember sorry). The first after 10 hours (break in) and if ok, then to establish a baseline with regular interval testing (100 hrs).
Usually, some fine particles would be found at break, then nothing (hopefully). This was in addition to having chip detectors.
We used Mobil 1 to prevent coking in the oil passages.
Any way, I think if you're inclined to do oil analysis, 100000 miles with an oil change every 5k doesn't tell you anything.
My experience has been that excessive wear on different jet engine or gearbox components can identify premature failure, but only when tested at frequent intervals. Also, I don't think the $28 cost/test, while not extremely high if taken at the mid point of every oil change would soon result in a greater cost than engine replacement.
Having said all this and perhaps boring anyone who bothered to read it, my other experience has been that my opinion doesn't mean a whole lot.
