I like what a Pennzoil rep said in the bitog q&a post:
"Motor oil formulations are a delicate synergistic balance of base oils and additives. When you add in one, you must adjust the amount of another. If an additive was added to specifically increase one area of performance, another area of performance might suffer. The Pennzoil Platinum® Full Synthetic motor oils with PurePlus™ Technology offer Complete Protection. We are confident in the overall balance of our formulation and would not change it to incorporate additional moly."
If only they would release results of the the SN/GF-5/dexos1/etc. tests to the public! Then we could compare which oil sways the compromise in favor of wear, deposits, low-temp viscosity, etc. .... Still, using massive moly might not hurt much and might just do something for start-up and cold-running wear like Idemitsu (and maybe Schaeffer) favors.
