They did? Someone has discovered magnetic organic molecules then.

Yes that was me. No insider knowledge, but the old (90's & 00's from memory) Castrol Magnatec had spec sheets the actually stated in writing that it contained esters, which were the polar molecules that attached to the metal surfaces, then they started using marketing speak about intelligent molecules.
I have been clearly told that the formula has since changed and no longer contains esters. But nobody uses Group I anymore in a modern SN oil, Group II and III and IV are all non-polar, while Group V includes Esters and everything else. So if it contains a polar molecule, it must be Group V since that includes everything not listed in Group I to IV.
Group V is a grab-bag term. It's probably an Alkylated Naphthalene (AN), as these seem to be replacing esters in some high performance oil, but that AN is just a guess.
