From what I've read on the ROC, there is something very unique about the 5w30 ESP SP version. As we've seen, it has no moly, no ester and much less boron. The guys on the ROC seem to suggest it's using some new Infineum system. To add further confusion, we know Triple Action was born from using additives outside the norm from the cosmetic industry.
There is also potentially mPAO in the latest 5w30 SP formulatin and they also could be using diblock VM. That could add to the price.
There have been several VOA's now per the Russian Oil club which all show the same numbers. There was also one UOA on that site where the oil was used for 9,600 miles and the results were very good.
This oil meets the Porsche C30 spec, which you can see exceeds API SP and dexos 1 Gen 3.
