I suspect 100% pure marketing BS.
Could it be the small ppm of moly Penn Long-Life uses?
Here it is in the 6th paragraph

I'm not sure Pennzoil has a patent on Moly Disulphide ?

It might possibly be the new EOP base oil that is to become a PAO alternative.
Something has changed, or they just refined their website. On 7/20 when I wrote down the specs, other than VI, I thought it was Mobil Delvac 1300S as far as the tech sheet. Very slight variance.
Now with the updated Tech/Spec sheet, the pour point has gone from -27 to -33 and the VI has risen to 136. So MolaKule, you are correct, as this is a real sleeper OTC oil for diesels. No idea how or what additives used to accomplish this or if it was just a paperwork update.

I don't know,,looks like a update to CI but still says it uses the Purebase to put the Pennstar additive in that resists shear. Guessing it is a new VII ?
Looks on paper that Delvac wins cold weather use marginally

The Pennzstar Molecule is just our trade name for the VII used in this product. We use to use this VII in all of our multivis oils until a year ago, now it is just used in the Long Life multivis oils. This VII was invented by Shell Chemical. We signed an agreement with them 6 years ago to have exclusive rights to using this product. I believe it is called Shell Vis 600. If you look at it under a microscope, it looks like tiny little spheres (bad spelling)and it is extremely shear stable. By the way, it is not marketing BS. This stuff really works.
Johnny,
Thanks for the info. I have been looking at this oil since July. I have seen oil analysis in the Ford PSD run on this oil with good results.

The exact ad was "Works Like Liquid Ball Bearings". Now, that was marketing BS. What a stupid way to try and tell the general public about VII.
anyone have any more info on Shell Vis 600?
what exactly makes it better? why is opnly long life using it? does shell use this in any of shell branded lubes?

I would GUESS, since I have no clue...
That the VII resists degredation.
Most oil sheer is the result of the oil breaking down because the "GLUE" won't hold anymore... it is pressed and cut and will not GO back into a CHAIN.
A better VII will be able to be cut up over and over and over with little change in the way it keeps comming back for more.
The lesser quality ones (VII's) will say make a come back (100 times) and the better ones will be able under the same conditions come back 10000 times or whatever thee ratio is...
So a good VII is like PlayDough and
a poor one is like a PlayDough that had
been exposed to a little too much "play time"
and will not work like the fresher playdough, the better VII's stay fresher longer...
This reportedly is the same VII used in the Pennzoil 5/20 .
That's a heck of a 5/20 at $1.24 per quart

Shell had a Dutch patent on the Star copolymer in 1977, in which polydienes or diene/styrene copolymers are reacted with divinylbenzene and then hydrogenated (hydrogen molecules are added to stabilize it). This produced one of the better and more stable VII's. They have since improved upon it and have given it another (internal) designation.
This upgraded VII is now used in all of the Pennzoil multi-vis oils, but not the Quaker State oils.
Out of the better VII's which 3or4 are the BEST IYO?
Which are the ones used most commonly and where do they stack up to the best?
Does this include the HM oils ?
It is in ALL of our mulit-vis oils.
