I don't think moly was added to most Pennzoil viscosities until the latest SL formulation though. I know the SJ 15w40 long life had moly, but I don't believe the 5w30, 10w30 or 10w40 versions in SJ formula contained moly.quote:

Let me just say that I'm glad you are on this board sharing your knowlegde with us. Great, informative answer.quote:

The powdered moly sulfide used in some gear oils and greases would settle out, but I know of no modern formulated oil that uses the powdered version.
Dave, I'd appreciate you supporting this comment. Where do you see this? There are many cummings engines running Schaeffers and I've yet to see where this statement is true.quote:

If you had a Cummins diesel you would not want Moly. It's been reported here that the Cummins roller cams can't get a good grip when Moly is used since friction is so low. That's why Delvac 1 is void of any Moly.

IMO, you want Moly. I'm convinced that it has helped Mobil 1 SS become a much better oil and if you look at Schaeffer's it really does a fantastic job. Loading up with ZDDP is not the answer IMO. But I'm no chemist either!quote:
ZDDP is a lower temp, lower load AW additive, while Moly and Antimony DTC and the Naphthenates such as Bismuth Naphthenate, are higher temp, higher load AW additives. While not a panecea, it certainly doesn't hurt to have higher load additive.
