I have searched for days through many many pages, and I can't seem to find a definitive answer to that question.
To be more specific, I would really like to know which of the currently available synthetic engine oils are in fact built either exclusively on Group IV base stock oil, or at least "blends" using very high percentages of Group IV.
From what I think I understand from studying the great technical articles here on BITOG (and other places), a "finished product" multi-viscosity oil that is manufactured upon a Group IV base stock, may not require any Pour Point Depressants, or Viscosity Index Improvers at all.
It sure seems to me like a better way to build a quality motor oil, rather than having to rely on those two additives to "prop up" the finished product. -Like avoiding having to deal with the long-chain polymer shearing problem inherent to VI improvers.
If anyone can "point me in a direction" that would be GREAT !!
Thanks.
