Friction modifiers are sneaky things -- Rotella T6 has moly oil in it now but the amount is very low.   As ZDDP goes down other additives that were commonly known as friction modifiers are creeping in to all the synthetics.

I am testing for it now by switching back to Rot dino as my Rot syn was giving me very minor warm up clutch slippage.

I checked Bob's for current VOA data -- issue is that nobody has tested any Rot dino since 2008 so any recent change becomes as a surprise.

I did go look at the Shell Tech pages and sure enough, they list Rot dino as 1,100 ppm zinc ..... aw shite, there goes another good oil getting sorta kinda wimpy on us.

This is the most modern independent VOA for Rotella Triple Protection I have found.

Next dino jug I try will be Walmart Supertech HDEO 15w40 -- the same stuff I used to always recommend as a clean up oil for abused bike engines since you could actually afford to change it monthly until the caked up gunk stopped coming out of your engine and you could see your oil level again in the little crudded up glass windows.

The way of things is wimpier and less  less zinc and phosphorus -- Rotella Triple protection is now down to 1,100 ppm zinc.   I suspect that all of the HDEOs are dancing to a CJ-x spec change so the rest may drop soon as well.

IMHO this topic has been given way more wind than it deserves.

Gus,

It's not about the question that you asked,  it's about the oils.  

Periodically somebody brings the topic up and we are reminded to go look at the oils again. This time we got a surprise and one of our favorite oils had changed formulations a little bit, but still it means we have to pay attention to it.

Dave mentioned the bump tables needed to be updated.   This is true, but until it happens I think we will find that the existing bump table recommendations for Rotella T (dino) Triple Protection are still good but instead of putting you at the top part of the scale the lower starting point will put you a little notch below max but still within the range of "good".
