I've had an interest in how Toyota formulates this oil since is was released and was hoping for a comprehensive VOA perhaps from PQIA but nothing to-date.
So this UOA and the MSDS kinematic viscosity spec's will have to do which are as follows:
KV40 30.08 cSt
KV100 6.72 cSt
VI 191
This oil is simply TGMO 0W-20 with less Viscosity Index Improvers lowering the HTHS viscosity @150C from 2.6 cP to 2.3 cP.
That's a significant drop in VI, but at 191 it's still way higher than any other 0W-16 and therefore it is the lightest 0W-16 at typical start-up temp's.
The only oil on par is also made by Mobil, their Mobil Super Syn 0W-16 which has the same viscosity spec's (it's the same oil) but with a less robust additive pac'.
In the decade TGMO 0W-20 has been on the market it has established a reputation for good shear stability so TGMO 0W-16 should be bullet proof.
For vehicles that are spec'd the 0W-16 grade, at least here in North America,TGMO 0W-16 has to be the oil of choice, any other 0W-16 is even heavier than TGMO 0W-20 at typical start-up temp's which largely erases any fuel economy advantage it might otherwise have.
Ironically the only oil lighter than TGMO 0W-16 on start-up is the expensive Eneos Racing Street 0W-20 with a KV40 of only 28 cSt and CCS of 3400 cP.
I did find Cam2 Synavex 0W16 with a quick search.

The Motul and Ravenol offerings have low VI's.
I anticipate trading my beloved truck in soon on a 2019 RAV4 Hybrid.
TGMO 0W16, here I come.
VOA, rapidly acquired UOA's to follow.
With Toyota's D4S fuel delivery system and mostly freeway miles,
my focus will be on extending OCI's and oxidative thickening.
Thanks for digging up the CAM2 Synavex 0W-16 PDS spec's.
The only way to know for sure if it's VI and other spec's hold up under scrutiny is with a VOA. It is so common for oils to fall short of their PDS spec's to some degree.
Anyway, based on the PDS info this oil will be heavier than TGMO due to it's higher 2.4cP HTHSV and KV40 spec's.
If you are going to order a VOA on TGMO 0W-16 I'd suggest requesting a KV40 test to be included.
