Higher moly content in budget synthetics

Does anyone know why the more budget friendly synthetics like QSUD, Rotella Gas truck, Havoline High Mileage have higher moly content (100ppm +) than the "premium" synthetics such as Pennzoil Platinum/Ultra Platinum, Valvoline Advanced, Castrol Edge, Mobil 1 AP, and Amsoil Signature which are usually 80ppm or less? Yes I know Redline is premium and has a ton, but curious why Shell for instance loads their lower priced synthetics with moly vs their flagship oils.

I've heard there some differences in the quality of the moly? If that's true, is that to say that 60-80ppm of a higher quality moly out performs 150-200ppm of a lower quality moly? Or is the view that since the premium lines have a better base oil, you don't need to compensate with as many additives?

I think there’s something to what you said however I don’t know that lower amounts of one moly are performing better than higher amounts of another moly. They many perform the same but it takes different amounts to get the same performance. I don’t have the knowledge to say if it’s six of one/ half dozen of the other or if there’s a profound difference.
