If it makes anyone feel better, I just did my first oil change on my Jeep and I am now considering one of these By-Pass setups. The dealer I purchased the Jeep from put in whatever oil was recommended in the manual less than 1200 miles before I changed it. I wanted to get fresh oil in since i had unplugged the MAF and did the EHM. Even at 1200 miles i was amazed at how bad the oil looked and felt. You could tell it did not feel like regular oil on your hands.
I know exactly what you mean by the oil not feeling right, it's due in part to the soot load. That is why I researched many options before settling on the FS-2500, including centrifugal and toilet paper styles. I found at least a half dozen different bypass filtration options. As far as I can tell, the individual filtration performance of all these bypass units is somewhat similar. The difference was small enough I did not consider it in my selection process. Some of the other units I found were almost as expensive as the FS-2500, but others were significantly cheaper; some were even way cheaper than the AMSoil unit. But all of the other units required that I choose a location, that I make any necessary brackets, that I cut hoses to length, that I assemble the collection of necessary parts, etc. The FS-2500 was by far the closest thing to a true "plug-and-play" bypass filter as I could find (other than the MicroGreens which I used with good results for my most recent 20K mile oil run, see
http://www.microgreenfilter.com/). My goal was to significantly reduce soot from the oil, and I think I have achieved that goal.

Do you think Rotella T6 is an appropriate oil to run out for very long OCIs ?
I ran Rotella T6 for about 20K miles with the MicroGreens, it was still fine. In fact, that's the oil I am using for the filter's inaugural run (because it was on sale at the time and cheaper than Mobil 1 TDT).
You are also right that the suggested 10K mile filter change interval is probably way too short for our small engines; these filters are usually put on big V-8 Diesels, two or three times bigger than our engines. What oil are you using right now, and are you doing a TBN analysis each time?
