JOHN: This Turco oil employs sodium as a dispersent additive. The metals should not be there but at
these levels, they aren't going to hurt anything. The viscosity was okay for a 0W/20 grade. The
insolubles are odd. This oil had a blue dye in it so we could not appraise the true color of the
insolubles materials. Usually, in a virgin oil with a lot of molybdenum in it (944-ppm is a lot) we will get
molybdenum back out of the sample when we centrifuge it. That may be the case here, where the
insolubles are additive that came out of suspension.

Did you shake the bottle before you took the sample? Or did you pour the sample from the bottom of an unshaken container??

I can't remember, so probably not. Good question, good point, I probably forgot, duh'!
