What is this stuff in the Vormax?

Car is running good - hence no new posts.

One thing that has been around for a few months now is this stuff at the bottom of the Vormax. It's not the same stuff as I mentioned before as this looks different and does appear to be going anywhere. The only thing I can think of what it might be is is dissolved solids - now obviously undissolved.

Because I heat the oil when filtering, to get it to flow better, I'm thinking that there must be some things that dissolve in the process then re solidify when the oil cools.

The strange thing is that I don't remember placing any hot/warm oil in the tank recently. In the past I have filled the tank while filtering (after checking for water) but now I realize it's best to let the oil settle. Besides I need to log whenever I add oil to the car for tax purposes.

I have not noticed any sediment in the bottom of the filtered oil cubees. I do feel it is safe to assume that this same sediment is on the bottom of my OEM tank, unless this stuff settles out as the Vormax cools.

For the time being I'm not concerned because the system is always purged back to diesel so I don't think stuff has had a chance to settle in the shared parts of the fuel system. I can always open the drain valve on the Vormax or remove the clear jar and inspect. The stuff in the main fuel tank (if any) would be another matter

The Racor filter has the same sediment though seems to be much less. Perhaps a long hot drive might clear things up.
