If you're running Archoil AR9100 oil additive and you have a bypass oil filter on your engine, this pertains to you.
I have a 55 gallon drum of hydraulic oil that I continually reuse and clean (polish) using a model X011303 Donaldson Filter Buddy. link to pdf file
I run a P560584 dewatering filter and a P165185 filter with a Beta ratio of 200 at 4 microns. (the highest efficiency filter offered by Donaldson for this application)
I use both Caterpillar, and Blackstone Labs for used oil analysis, and the last time I sampled the oil it showed no water and an ISO cleanliness code of 18/17/14. Which is cleaner than new unused fluid, which rates at 21/18/14.
After this last report, I ran two of the P165185 (ultra-fine) filters in tandem on the Filter Buddy for another two weeks non-stop, and the back pressure indicators on the filter heads showed no resistance at all.
I've used AR9100 in my 2002 7.3 with good results. And a friend's 2005 6.0 showed improvements too. So I decided to add it to the hydraulic fluid batch.
I dumped about a gallon of AR9100 into 35 gallons of fluid, which is lean because the directions call for 3.2 ounces per quart. Meaning I should have dumped 3.5 gallons in it.
The filter was running when I added the AR9100. I dumped it in and focused on another task. I came back to the filter assembly about 10 minutes later, and noticed that both restriction indicators on the filter heads (plumed in series, not paralleled) were pushed all the way in the red (50 psi of back-pressure). So in 10 minutes time the AR9100 clogged two filters who previously showed no signs of any back pressure at all.
So now my questions is, if you're running a bypass valve on your truck, like me. Does all the good stuff in the AR9100 get stuck in your bypass filter? Does it clog the bypass filter rather quickly and make your bypass system ineffective?
I'll e-mail Archoil and ask these same questions after the Holidays.
