If the archoil can settle out of the carrier oil in the can on the shelf,,,, then it can also settle out of the engine oil in the truck. Its not dissolving, is dispersing (like soot doesn't dissolve in oil, it disperses).

Diesel engine oils typically have a lot of dispersant additive to keep soot in solution, but if the archoil is saturating the engine oil such that it can't hold any more solids in solution, then well, those solids gotta go somewhere (which is normally how sludge forms in engines).

I theorize that the reason some people are seeing issues, and some aren't, is because of the dispersant additive package/ suspended solids holding ability of the engine oil the archoil is being added to. Higher quality oils with have more dispersant additives and can simply hold more suspended solids in solution.

It would appear archoil is effectively taking up some of that suspended solids holding capacity, and perhaps exceeding the suspended solids holding capacity of some oils (this would be especially troublesome if say someone where running lower quality oil and overdosing it with archoil ).

The "mineral" elements disperse (Potassium Tetraborate, etc). The majority component organic carriers (the esters and paraffin that will thicken) will dissolve. It is clearly the organic carrier that is what clumps/thickens (you can see it go back to a liquid state with heat).

Bismic, I just changed my oil with Motorcraft oil filter and the package came with that adapter. Should I be pulling that out? Why would it come with a Motorcraft filter if it's not to be used?

The real OEM filters never come with that adapter. You must have an aftermarket filter labeled as Motorcraft. Where did you buy it?

Local parts store, O'Rielly's, I got it there because it was Motorcraft. I started my 6.0 journey by watching all of Diesel Tech Ron's videos so I've always used OEM filters. I just went to see if the box was still around, but it's already been taken to the dumpster. My fuel filter box was still there though and it says Motorcraft.

Not a real OEM filter.

If you want authentic OEM, then buy from DieselFiltersOnLine (for a discount - either Motorcraft or Racor), or at a dealership. If you would go buy one from a dealership, you would know what I am talking about.

I've not had any trouble with Parker/Racor from Dieselfiltersonline.com they seem to still be legit.

I’ll do that from here on out. Normally I’ve gotten them from the dealership, but it was pointed out to me that they had Motorcraft in stock at the local place. I’m wondering if someone switched boxes because a they are substantially more than a WIX. Every is out on the shelf so it’s a possibility.
