If you've been doing fine with the PP additive package, why shift to Mobil Super 5000 which is quite different?
Pennzoil conventional, like PP, is still a high Ca oil with plenty of Boron and Moly. Mobil Super 5000 is a weaker Ca, high sodium oil with no moly, no boron. Mobil Super 5000 is more like the Valvoline conventional and NAPA oils.
