The street version has a nice shot of zinc for anti-wear and moly for friction modification. But phosphorus is low to get the API/ILSAC certification and to keep it cat friendly. It likely also has higher detergent levels.
NOACK volatility is within allowed limits but I’m surprised that it’s at 12% when the allowed limits are 15% and the better oils are closer to 10%. Probably due to the limitations of the Group III base stocks.

My Blackstone VOA on Sustina 0W20 actually showed phosphorus content significantly higher than zinc.
I point to high density as a positive attribute.
It astounds me that these oils with VI's of 229 and 239 have NOACK's of ~12.
I have used Ravenol 0W16 for ~ 50k miles w/10k OCI. It is designed with a reasonable NOACK, low VI, ~ 40% ester content, and 2x Mobil 1 trimer moly. It is quite stellar.
PLEASE report this to Shannow.
FWIW, my new favorite oil is Valvoline Advanced Full Synthetic 5W20. VI 147. NOACK 7.6. I am now in a marathon mindset, aiming for such things as clean piston rings at 500k miles !
It is hoped that this Valvoline oil is a bluesubie approved oil, although maybe a little thin for your taste.
