Anything added to the base oil, including elements like Molybdenum, Magnesium, Calcium, Prosperous, etc, are still technically "additives" to the oil. Semantics.
From info about motor oil analysis done by Blackstone and others, they use ICP (inductively coupled plasma) Spectroscopy, which detects the elements added to the oil, and those elements are shown in ppm on an oil analysis report.
