Synpower 5w30 now does indeed show a 7 NOACK rating on their website for 5w30 while Ultra is 11.9?
Is this a sign of a superior basestock? Redline and Amsoil are consider top tier oils in many minds and now Synpower is very near them in NOACK.
Dont get me wrong I have used both (currently Ultra is in vehicle). Like that Ultra has Moly and Boron where as Synpower does not for the most part. Maybe Ultra's higher NOACK come from having a more substantial add pack?
How is better NOACK typically achieved during refinement. More PAO used or better refinement and harvesting of uniform group III molecular size?

What gives with Synpower giving
I suspect 5w30 is the base stock for many if not all the other grades and altered through viscosity improvers or something of the sort and as such why their NOACK numbers may suffer a bit compared to the 5w30 ? ? ?
