I'm no oil genius, but it sure doesn't look like there is an abundance of Zinc (Zn) and Phosphorus (P) in that oil. According to this chart https://www.mobiloil.com/USA-English/MotorOil/Files/Mobil_1_Product_Guide.pdf , even the much-maligned Mobil 1 0w40 has more Zn & P than the 5w40 Royal Purple. On the plus side, if your car burns oil the catalysts won't be quickly poisoned.
