I should also mention that ASTM D341 fails for oils using a PMA VII. Therefore, if indeed a PMA VII is used, all bets are off.
Verification of the density and ASTM D341 extrapolation in the VII and HTFS calculation
It would be interesting if Total indeed used a PMA VII. It would be strange if they did because Mazda recommends this oil in its newest turbocharged engines as a PMA VII increases the deposits substantially, but the formulation may have changed now. If someone can find out a PMA VII was used or not in this oil, it would be great.
For what it's worth, the Pennzoil DEXRON® III/MERCON® ATF uses a PMA VII, but ATF temperatures are not nearly as high as engine-oil temperatures and the thermal stability of the VII is much less of a concern as a result.
