Actually all the rest of the world save Germany goes by exactly the same thing that the US does. In fact the US was one of the last to change their marketing practices.

Real synthetic oil?
- Thread starter ron17571

Actually an oil is classified as a "synthetic" by the process it undergoes to become a base oil.
sniffs at this boring thread as I drive to 10k ocis on Kirkland synthetic with no downsides. Decides not to Pee on it Since this was covered a couple of decades ago here. Moving along.
Don't be fooled by those oil adds on T.V; Synthetic oi is NOT made in a laboratory by young women in clean
white Lab coats wearing Oversize Safety goggles.
Developed? Yes. Made in quantity? No!
It is an advertising Term agreed upon by the The National Advertising Division of the Council of Better Business Bureaus and The big Oil Co's after a bit of contention.
SAE said they are not going to touch this hot potato so that definition is history.
"The Definition of Synthetic Shall be Stricken from all the records and obelisks!"
"So it is written, so it shall be DONE!"
Now you know the power of Oil!
It was already being done in nearly all the rest of the world, both Mobil and Castrol were selling Group III based synthetics elsewhere.
Mobil knew knew that if it went to court they would lose due to this fact. It was truly a tempest in the US teapot by then.
... and from a place rich in German history! How could you ?!
vollsynthetisch über alles !
Learning a lot here, thanks everyone for the good information and for the kind corrections to my statements. Until now I thought that PAO and Esters were the only true synthetic base oils, and I thought the Group 3 / hydrocracked stuff was called "full synthetic" only because its performance (as a finished lubricant) is "close enough" to those true synthetics... guess I should re-read the home page article lol.
Just curious as to where you got that info from?

integration by law.
there remains some great architecture and cultural carryover. The California winery craze is taking over Fredericksburg lands and crowding the breweries. But the History of the area is beautiful And unique.

Here's one link, and there's a few white papers on it as well.
Performance of Base Oils and Future Trends - The Evolution of Base Oil Technology - Part 3
This is the third of a three-part series on base oil technologies and applications. Lubrication technology evolved slowly from ancient times until the 1950s. Solvent-refining technology then...

Another interesting data point is the old ExxonMobil presentation on their Visom product which was produced in response to a projected PAO shortage. How today's Group III base stocks compare to Visom is a guess (especially GTL base stocks as noted in the presentation), but it is still relevant today:
NO, you are correct the industry has bamboozled the consumer. But that was long ago.
I am not saying traditional synthetic formulations are better, with it's concomitant extra cost, but it surely can be for some.
Now I recall my 1988 VW Fox had a statement in the OM to NOT use synthetic oil in the 1.8L

My 300X’s owner’s manual says in bold print “You can use synthetic or mineral based oils, but do not mix synthetic and mineral based oils”.
I doubt Group III can do all of this simultaneously. Both "additive solubility, lubricity and antiwear performance" are three terms for one single thing and you could also substitute it with aniline point. It's important to remember, the more you refine/hydro-crack mineral oil, the more you elevate aniline point towards that of PAO. You gain something, you lose something. The often claimed "better solubility" is barely more than a popular myth. As a matter of fact Group IV/PAO with a slug of ester will easily match or surpass additive response/solubility of Group III. That's how proper PAO based oils are blended.
Btw, it's hard to find any Group III (incl. GTL) PCMOs with a poorpoint of -76°F or even -87°F. Do they even exist? There are several PAO based PCMOs with these numbers.

But the point is you can make a competitive Group III synthetic for a lot less cost than Group IV/V. Blenders were looking for a cheaper way to make synthetic and, at the time, there was a real fear of shortages for materials to make Group IV/V.
That was 1996 and 1988 mentality.
SP was never the goal with PP/Helix Ultra 5W40, it comes naturally with its add pack
SRT 0W40 is API only and the a3/b4 flagships make a mockery of it

But what rationale exactly make petroleum and automotive engineers come to that conclusion? There had to have been something to it.
