On German version bottle it says: Synthetic technology NOT Full synthetic.
So why would they market their oil for German market as Synthetic technology and on other markets as Full synthetic?
There is no doubt that oil contains synthetic base oils, but predominant base oil is still GroupIII.
They advertise Mobil1 0W40 same, SHC oil, and it is predominantly GroupIII oil.

You have to take what's on the can with a pinch of salt sometimes as it's quite common to have oils listed as semi synthetic/synthetic technology indicating a mineral oil/synthetic blend and it's actually full synthetic in the can, Shell Helix AX7 AF is an example of this.
The Mobilube SHC 75w-90 transmission oil is PAO but as you can see contains the phrase SHC
when you look at Mobil msds's they list it like an ingredient list with the biggest first and PAO listed as synthetic base oil and group 3 synthetic as highly refined mineral oil
There are advantages to using group 3's over PAO so I've got no probs using them,PAO's don't have very good load carrying ability, less than a mineral oil I think, it's just got very good cold fluidity and high temp low deposit performance
If you read the blurb on this you'll see that Mobil mean synthetic hydrocarbon when they say SHC

"SHC synthetic technology" may just be a marketing term for a blend of PAO and group 3 synthetic which Mobil 1 0w40 now is and they've decided to roll that term out to all Mobil 1 products but with a synthetic base oil listing in the msds and -45'C pour point the Mobil 1 ESP 5w-30 is PAO.
Let me try to understand this:
Mobil1 was selling few years ago Full Synthetic oils in Germany (advertised as full synthetic) and now they are selling it as SHC as marketing trick? And that happened when they moved from majority PAO stock. Interesting.
I am constantly saying, M1 ESP has inside synthetic base oils, but it is combination of GRIII and either PAO or Ester, probably Easter, considering pour point and flash point (+254c) as well as TAN (2.22) and extremely low NOACK.
But, predominant base stock is GRIII (whatever Mobil1 is using).
So Mobil1 is selling their oils as Full Synthetic in all other EU countries (ESP is made in Finland) but only in Germany they are using SHC marketing trick. Yeah right.
Do not get me wrong. I am not saying oil is bad, I am using it, but it is predominantly GRIII.
On other hand, Pentosin Super Pento III is predominantly PAO oil, but on paper not as good as Mobil1.
I think you may have misunderstood what I have said
SHC means Synthetic HydroCarbons which is PAO, it's what ExxonMobil mean when they say "SHC"
On the bottles in Germany it says "SHC synthetic technology" which sounds like a marketing term to me. If SHC meant synthetic hydrocracked then the term would be saying "synthetic hydrocracked synthetic hydrocracked" since synthetic technology means hydrocracked synthetic oil, it just would not make sense grammatically.
It would be similar to the Spielberg film "E.T the extra terrestrial" E.T. stands for extra terrestrial, so essentially the title of the film means "Extra Terrestrial, the extra terrestrial", silly.
Shell and Mobil have been trying to "globalise" their oil products for the past couple of years so I'm thinking that they've come up with the "SHC Synthetic Technology" term to put on all their premium Mobil 1 products rather than have Full Synthetic on one bottle and Synthetic Technology on another.
I've stocked 208 ltr barrels of Mobil 1 ESP 5w30 in the past which was confirmed by Mobil as PAO, as well as their Mobil Formula V 5w-30 which is sold as a different formulation but it's the same oil with the same specs as ESP just without so many approvals.
ExxonMobil are the biggest producers of PAO on earth so it makes sense for them to use it.
Mobil 1 ESP 5w-30 is not a GIII/Ester blend
