Mobil1 5W20 updated it spec sheet. What the heck is.....

[CB900F2]

Mobil1 updated their SDS sheet for the 5W20 dated June 2021 from the old one of July 2020.

On the new Jun/21 SDS, what the heck is

DECENE, TETRAMER AND TRIMER HYDROGENATED

is TETRAMER and TRIMER a more fancy word for PAO ?.. or is it something else?

How does this item compare to the Jun 2020 version?

Thanks all!!

Would seem to be a 4 molecule and 3 molecule construct.

what does that mean for a laymen like me??...

Yes, it's PAO.

The very first link on Google when googling "1-decene oil":

1-Decene: An Overview Of Disruptive Petrochemical Industry​

Industry : Organic Chemicals

Increasing popularity of synthetic lubricants as they offer better lubrication has triggered poly alpha olefin demand over the recent past. Poly alpha olefin is prepared by oligomerization of linear alpha olefins (C-10 and higher). 1-Decene is the most preferred alpha olefin for poly alpha olefin production as it is the purest form of PAO. Increasing PAO demand for producing engine/gear oils, greases, and other lubricants is expected to be the key factor driving 1-decene market.
1-Decene is stored under a nitrogen blanket and is not corrosive to steel or aluminum. It should be avoided from the contact of air or oxygen because alpha olefins are sensitive to moisture. Alpha olefins should be handled under a dry, inert gas atmosphere otherwise it can form explosive mixtures with air or oxygen in certain concentrations.
Currently, most linear alpha olefins, and thus 1-decene, are commercially produced by ethylene oligomerization. Products of oligomerization process consist of even-numbered carbon chains ranging from C4 to C30+. 1-Decene is obtained only through the linear distribution of alpha olefins obtained. On purpose production process for C-10 has not been yet developed.
