The moly in the latest sample is interesting. Was moly added to the latest CI-4+ formulation of Delo 400?

It appears that Moly and Boron both have been added. Nothing else beside Delo has been put in the truck since I've had it. Maybe good oil just got better.

Cool, were the ratings on the bottle of this sample different than those in the past? (want to make sure what I buy will be same)

Sorry, I'm not sure as I had some of the old and the new sitting in the barn so I'm not positive. It would have to be some of the new CI-4plus I would imagine.
