What you are seeing in most of the traces are spectrum indicating majority PAO base fluids and complex polyolefin (co-oligomer) esters.
Many of the traces are showing what we call various "isomers" or various molecular weight PAO molecules indicating this is a mixture of various PAO's and co-oligomers or "complex" esters.
These co-oligomer esters, derived mostly from PAO and other polymers, have the advantage of providing shear stability without the need for viscosity index improvers. If the oil is very shear resistant, then wear is potentially reduced at high temperatures in the hydrodynamic lubrication regime. The large molecular weight hydrocarbon spectrum(s) we believe are of the complex "co-oligomer" esters.
Combine the fact that this is an upper 30 weight oil with the low temperature PAO cuts, and you have an oil that has good BPT's as well. The viscosity index is most likely better than than that stated in the Product Data Specifications.
For mixed lubrication or boundary lubrication regimes, the zddp and Ca provide the bulk of the primary and secondary AW additives with Mg providing the dispersant and FM capabilities.
The data to-date reveal no di-esters or conventional polyolesters contained therein.
The data to-date is also absent of any naturally derived esters such as from seed oils. At first, we thought certain refined seed oils might be contained therein, but no naturally derived fatty acid molecules have revealed themselves.
IMHO, the formulators and additive suppliers have done a superb job in developing a most interesting PCMO.
