Well im not a blender but 900 ppm seems like over kill to me.


Honda and Toyota don't seem to agree.

Explain?


Here is a VOA of Honda, Toyota, Red Line and RLI 0W-20 oils. Lots and lots of moly.

Molybdenum is a metal and only metallic-based additives contribute to sulfated ash.

Maybe, but then you have the issue of added amounts (albeit minimal compared to other wide grade spectrum oils) of VI improvers (also in RL's 0W-30, 0W-40 according to Dave, but not sure about their 0W-20), and their possible propensity to shear down.
One of my "other" reasons for the mix instead of just pouring in their 5W-40.
