Were all of those 300k kms Camrys serviced by the dealers and with 0w-16 oil?
It’s been my experience here in the U.S. that dealer service departments use whatever they want, to include viscosity.
I know of several dealerships, including Toyota, that use only two grades (0w-20 and 5w-30) of bulk oil.
I’m surprised the 0w-16 is recommended for your locale as I’m not aware of any CAFE-like requirements overseas compared to the U.S.
