I'll tell you what your are seeing, then YOU can tell ME what we are seeing (I Hope)...
Both oil samples are essentially from the same source(s). 85% oil I know about (from work), 15% "gimmie" oil from reasonably trusted sources.
Oil in RIGHT has been centrifuged (simple centrifuge) twice and let settle for a month or more.
Oil on LEFT was my first attempt at mist washing. It turned it into a horrible emulsion, but then I heat settled until the crud dropped, drained it, and then centrifuged twice as well. It is certainly a lot lighter in color but still has a distinct haze. I am not concerned about the creamy at the bottom that is the hydrogenated portion of the PHO oil my source uses. I AM very concerned about the haze though.

I have not hot pan tested either source. I am not sure how much I trust my analysis judgment on hot pan test having never done it. The few YouTube videos I watched of it were poor quality and not very helpful.
Not sure what all this adds up to, except that the more I screw around trying to perfect my filtering system, the worse off I seem to be doing. That dark oil is so clear and all I did was chuck it in a barrel, pressurize it, and shoot it through my centi nice and slow. That mist washed sample scares the heck out of me!!
Oh, the one other difference I can think of is that the dark/clear sample was pushed nice and gentle through the centrifuge using an air operated barrel pump. It only pushed what the centrifuge feed valve required/allowed. The light hazy sample was pushed violently through using a 1” clear water pump with the bulk of the oil (the bypass volume that the centi coulend take) circulating back into the mist tank. Come to think of it, I am starting to think this may be the culprit. That violent mixing is certainly what caused my emulsion to begin with.
Please advise.

) I decided to try my hand at mist washing. - UG not sure I am going to do that again. At least not in combination with the clear water pump.
