I say Noack is overrated-just like many used to say viscosity index is overrated. The Noack test is conducted at a very high temperature. It is not necessarily indicative of engine cleanliness.
Oils of the future will be thin. They will have high quality, moderately expensive base stocks. Additive packages will not need to be so robust. The key question will be how long before they shear beyond acceptable levels. Just one man's opinion.

Do u daily drive it? If so, how is your driving style? Because I switched to motuls 8100 5w30 for my ago kit, and I noticed it takes a little longer to reach operating oil temps (90-100c)
