Here is the PQIA 2019 VOA of QSUD 5W20 http://pqiadata.org/QuakerState_5W20.html It looks very good TBN of 9.16 with a LSPI friendly Ca & Mg detergent mix Zinc near the top end of the ILSAC limit at 864 ppm Healthy Boron at 113 ppm Lots of Moly at 181 ppm Great Noack volatility at 7.1 % Rated SN-Plus and Dex1-Gen2 I know you got the 5W30 but given most oils are matrix developed (one add pack for all grades), I would assume the 5W30 would be very similar.
