The QR codes represent the back and front labels only -- they don't reflect actual formulation changes. They may change or not with or without formulation changes.
Interestingly the plant code on the Mobil 1 and Mobil Super bottles seem to be 110 while on the TGMO and Mobil Delvac bottles, it seems to be 102. I remember the TGMO being made by the industrial division of Exxon Mobil when I gave them a call. Perhaps Mobil Delvac is also made by the same division. In any case the TGMO has always been a different beast than both the Mobil 1 and Mobil Super.
Ah, from the revision number, we know that this is the same formulation for which PQIA has a VOA on it! So, OP, perhaps don't waste your money on a VOA -- there is already a good one. Nevertheless, if you could send it to Wear Check USA, we could know the oxidation number and if there is still ester in it, as the old formulation had a lot of ester.
It's a high-moly (not the Infineum trinuclear moly but the sulfur-free Vanderbilt moly) GTL-based formulation -- explored in glory detail in the following thread. It's good to know that this is the current formulation. Interestingly I had a batch with exactly the same label as on the PQIA site except for the revision number -- mine had RN5953. When I had a UOA, mine turned out to be the old low-moly Group III formulation with the Infineum trinuclear moly.
Is TGMO 0W-20 SN made in Heaven? Part II: high-moly GTL
