I originally posted this in the oil filter forum but I think it's more on topic here.
I'm doing an AutoRX treatment on my newly acquired 2007 Entourage and decided to change the filter at the half way point. Based on what I saw in the filter canister when I did the first oil change right after I got the van last month I think this engine was neglected for its last couple of oil changes. The fresh oil the dealer had put in was already doing a good job of cleaning out a lot of junk, having only been in there for about a month with less than 100 miles on it. That's why I decided to do a full ARX treatment.
Halfway through the ARX run there is quite a bit of junk in the filter pleats and a little in the filter canister. When I did the first oil change after getting the van it looked worse than this.
It doesn't really show up in the photos, but I can tell based on the texture and color of the filter media that most of the "cleaning" that ARX does is by solubilizing the gunk. I think that's why Frank recommends a filter change at the halfway point because as the media gets saturated with the goo it gets restrictive enough to cause the filter to run in bypass mode.
