It IS different than other group III in that its is a textbook Synthetic not a fraudulent (i.e. marketing term) synthetic.
I am not talking about base oil performance here, just impropriety and obfuscation in API marketing.
This post makes no sense. First off, the Group is not intended to represent finished oils, that is a construct often seen here on Bitog but not the intention of the designations. Secondly, if this product is exactly the same as other Group IIIs then why would it be designated a Group V? No oil formulator would agree with your comments when viewed in light of the reason the Group designations exist in in the first place.
Lastly, your belief that the designation comes from some conspiracy by ExxonMobil is just.... well it is completely unsubstantiated and silly. Your circular reasoning that the designations ascribed by the API itself are are an obfuscation in their "marketing" is again linked to the misguided belief that the Group is directly representative of a finished product - which is a misunderstanding of API 1509 Appendix E. API 1509.
You say you aren't talking about base oil performance yet that is exactly what you should be talking about when discussing a Group designation.
