Mola's Comments: This analysis doesn't show the Sulfur, Nitrogen, or Boron additive components, nor the base oil's, but does give one baselines for comparison to future UAO's.

[Al]

Since the Zn is so low what compound is the Phosphorus in?? Obviously not ZDDP

Al,

It actually is the ZDDP.

Additive suppliers can give you ZDDP with greatly varying amounts
of zinc, phosphorus, and sulfur.
