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.

Check out the new Valvoline Modern Engine Motor Oil if you like Valvoline. Probably less of a need in an 86 though since intake valve deposits aren’t a concern like they are in the 2.0DIT.
The new Ascent specs 0W-20. Good luck to all of those beta testers!
