Good morning, I discovered this site in 2004 and it is the #1 site for lubrication information thanks to everyone here. I use the VPB in my Jeep 4.0, as well as T5 and Motorcraft super duty all 10W/30. From reading on here, and the PQIA, (PQIA had nothing on VPB in 10w) none of these HDDO have moly in the formulation, but i was curious about VPB. Called Valvoline, they couldn't answer the question on the spot. They emailed me last week saying that the 10w/30 contains approx. 50ppm of Moly. From what i gather, as long as the other anti wear adds and detergent level is approx. the same in all 3 of these brands, the VPB may have the edge in anti wear with the small amount of Moly. All the stuff i have is CK-4 according to the API circle on the back.
