I believe the NOAK volatility is around 9-10%, which is what Amsoil S2k is (9.3%). I have found Mobil 1 10w-30 to be the best oil for volatility and Amsoil 10w-30. M1 10w-30 is 6% NOAK.
 
Buster,

Actually the latest Noack specs I've seen for Amsoil are:

0w-30, 8.6%
5w-30, 4.9%
10w-30, 5.5%
15w-40, 6.3%

This is based on testing done in March of this year ....

The following specs for M1 0W-40 are from the New Zealand Mobil web site.

Vis. @ 40 C 80
Vis. @ 100 C 14.3
Vis. Index 187
Vis. after shear 13.4
CCS Vis. @-35 C 5600
NOACK Volatility 8.8%
Flash Point 230 C
Pour Point -54 C
 
Cool, that NOACK figure seems low enough.

I wonder why it's not listed on the US site.
