There is a detailed PDS of the Mobil1 0w40 ? (not the ESP version)
I have these data but the Noack is not mentioned
The flashpoint and TBN are very good
Castrol is using ASTM D93 method to determine flashpoint.
Also I did several used oil analysis on Mobil1. While Mobil1 has very good TBN, retention rate is not good. But you will not have that problem in EU considering sulfur level there (ULSG).
However, in EU you do not ahve to worry about stuff we worry here. Burn is different in EU, gas is better, you can drive much faster and worry less about carbon build up. If you go with Castrol 0W40 you will be fine, if you go with M1 you will be fine. Take into consideration that Castrol is also "true" synthetic (PAO based) and Mobil1 that is available in Germany is HC based. In the end final product matters, but you will be fine with both.
