I understand Tim. The better the filtering the better off your motor is. The small stuff gets between the cylinder wall and the piston causing scuffing and the bearing surfaces causing them to deteriorate in short order. This small stuff is a real problem. GM did a test some years back and showed proof that the engines lasted 7+ times longer when filtering down to this level. I know the diesels already last a long time, but when you turn up the wick, it wears them even quicker from this. Plus your emissions stay low and fuel mileage up over the years from lack of wear. I call my system the purifier. I did it for the trans too because of the wear on the clutch plates and steels. I've seen my spin ons from my Allison after 5K. I didn't like it. That's just me though. I've been doing these on local trucks around here and they ALL love them. Yes it's a cat fuel filter that is $15 from the CAT dealer (cheap oil purification). I do them in singles, the dual for our trucks. A dual that mounts on the frame or in the bed, and a very LARGE single for anything you can fit it in including motor home campers, earth movers, or over the road big rigs. They handle 250+ deg oil just fine as does the hoses I use. There is a company that likes them so much that they want to start supplying them in private autos, commercial apps, and marine use. Oil does't wear out. It only gets broke down from heat and contaminants. This removes the contaminants. The things that the auto industries screw us on is crapy filteration (if it was sufficient, the vehicles would last much, much longer and there revenue would fall because of lack of new vehicle sales), NO dang egt gauge (for the charged autos and diesels), and NO oil temp gauge. All these equal a much longer lasting vehicle with less issues. My purifier feeds the filtered oil back into the oil fill hole (side not the top) so you remove the cap to see it working and you can also see when it's getting clogged. If it does, it's a non issue because you still use the stock oil filter the same as before. The trans filter dumps back into the spare dip stick hole.
