That Noack is very easy to achieve in 5W30. What is exceptional Noack? Mobil1 0W40 is 8.7%. Or Castrol 0W40 9.1%. Or previous version of Mobil1 ESP 5W30 LL04 5.6%.
Castrol Edge 0W30 and 0W40 are basically same oil except 0W40 has more viscosity improvers
0W30 has Noack 8.1%
0W40 has Noack 9.1%
It is bit more complicated than that (0W20 oils have higher Noack generally) but in discussion about ACEA A3 and C3 oils this is basically rule of thumb.

Just thought it was a better Liqui Moly alternative to what he was considering.
