High Noack indicative of less than stellar base stocks?
No, the CCS is pretty low. You need to take the CCS and Noack simultaneously into consideration. Therefore, the base oil is likely Group III+ and/or GTL.
The additive package seems outdated with no magnesium and a weak TBN despite the high SA.
An MSDS shows that it is made by Total.
Note that the viscosity index VI = 219 is ultra high, meaning the base oil is very thin and the VII content is very high, typical of Japanese-OEM oils aimed at improving the fuel economy through a ultra-high VI by increasing the VII content, which could compromise the engine wear and engine deposits.
Therefore, the reason for the high Noack is the very thin base oil. The base oil is otherwise still Group III+ and/or GTL according to the CCS and Noack.
Interestingly the oxidation number, if correct, may
indicate the presence of a small amount of a POE (polyol ester) base stock (3 - 4%). I saw the same thing with the TGMO 0W-20 -- it could be another Japanese-OEM thing not talked about.
