Thanks for posting this. Yes, the bottle tells (almost) everything.
There is a four-digit formulation number (revision number) on the back label of all ExxonMobil oils. By looking at this number, you can tell what the formulation is.
The original TGMO 0W-20 SN had RN5953. It was Group-III-based and looked liked it had a lot of polyol ester (POE) if my FTIR oxidation number was correct. It also used trinuclear moly.
Years later PQIA tested a TGMO 0W-20 SN that had RN6378. It was GTL-based with a very high amount of 787 ppm sulfurless Molyvan 855 moly. It also likely had some POE according to Russian FTIR data, but it was only a few percent if at all. TGMO seems to like to have ester.
The SN PLUS version you posted also has RN6378; therefore, the formulation hasn't changed for the last two years or so. You can see the PQIA VOA of this formulation
here. Note that the PQIA version is labeled SN but it is the same RN6378 formulation.
Now, someone needs to find the SP bottle so that we can see if the SP formulation is different.
Moreover, if you could also post the four-digit RN numbers for TGMO 0W-16, it would be appreciated. In a few years most newer Toyota engines will use 0W-16. Already almost half of them use it.
