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
