On the factory installed Mazda Skyactiv they use 0w-20 high moly in naturally aspirated cars but in the turbo version they use 5w-30. The moly is significantly reduced in the 5w-30. For my 2019 Miata it is recommended in Mexico to use 5w-30. What is your thoughts on this?

My understanding is Mazda FF usually contains tons of moly. So where's the moly?
