I used to drive this truck back in college (quit for several years, then started again about 4 years ago) and remember antifreeze leaking out the cylinder head at one point. Being a poor college student I threw in a bottle of the sealer and it went away.
So the potassium that shows up isn't a ton and tested negative for glycol, but I do have to add a small amount of coolant every few thousand miles. I did replace the oil cooler o-rings on this three years ago and it could be the gasket isn't lined up perfect allowing a small seepage of coolant into the oil.
For the boron Schaeffer's doesn't use it and this is the second oil change with Schaeffer, so I'm guessing its from the Rotella that I have used sometimes to top it off. Note that the oil makeup isn't from burning oil, its from a mysterious leak around the filter housing.

The Motorcraft FL-1995 filter looked really good, no tears, waviness, etc. One thing to note is on these filters there isn't an anti drain back valve since the filter sits almost vertical.
