I am posting the latest UOA on my 2020 Toyota Avalon Hybrid on TGMO 0W16. The first UOA using Mobil1 0W16 is available follow the red fint link below. I now have 18,774 miles on the vehicle and 8,970 miles on this UOA. The mileage math will not add up exactly from my first UOA shown below since I sampled the oil a few hundred miles before it was ultimately changed. This continues to look very good to me. I love the high Moly but both oils appear to be providing excellent protection. Silicon appears to be trending down as expected. I think this is probably from engine sealants. The oil was changed yesterday by my Toyota dealer. Again their service report shows that they used TGMO 0W16 again. After this next run, I will most likely just start using the Mobil1 0W16 but would be interested in the group thoughts. Not sure why my formating changed after posting but the first number for each parameter was using Mobil1 0W16 and was taken after 7k miles of use. Total miles on unit at that time was 6.1k

Prior UOA Discussion 1st UOA Mobil1 0W16 6985 Miles

The testing company was CAT SOS Laboratory.

Are they using the SP/GF-6B labeled oil ?

Up until recently, the bottles were labeled SN+.
I wasn't able to see the oil container. The part number on the service record is 00279-blk16-01. I talked to the parts guy and he indicated that this is the Toyota part number number for bulk Toyota 0W16.

Based upon this UOA, and upon smithph's VOA with substantiated TGMO 0W16 SP/GF-6B, I am going to reach the following conclusions.

TGMO 0W16 SP/GF-6B has twice as much boron and 25 per cent more moly than the SN+ formula.
That certainly appears to be the case. I found the link to smithph's post here:

It has the funky triangular API symbol on the front label which signifies GF-6B to only be used in engines calling out 0W-16. See post #9.

This article seems to reference 4 wt% as the optimal boron concentration. How does that convert to parts per million? I couldn't find any conversion that had a believable number.
4% is 40000 parts per million ....aka .04.
