Titanium seems to be interchangeable with molybdenum. So from what I've seen its one or the other.
And I wouldn't ever expect to see titanium in a pennzoil product simply because they have the best additive packages available due to infinium,along with Exxon.
While I agree that SOPUS and Exxon make great oils I think there are also great oils made with Lubrizol, Afton, Oronite, NeuMarket etc...additive packages.
I would love to see a list showing which oil uses which companies additive package?
It would probably help with knowing which oil are more compatible with each other.
I remember reading that Pennzoil's original PAO synthetic (Performax) used an Oronite (Chevron) additive package and it was an excellent synthetic.
