I would have to agree with the Liqui Moly part. I used it immediately after ZIC, and it was just worse somehow.
Moreover, I did some research about the 'Synthesis Technology', apparently it is the same standard as the rest of the world's 'Fully Synthetic', but I think it's better to be safe than sorry.
The oil Toyota Indus sells here, the 0W20, is Semi-Synthetic. But they're putting that in the Camry; i.e. they don't know anything.
