I just checked with Daimler and there's no such thing as a 229.4 engine oil spec.
Amsoil AFL 5W-40 claims to meet:
Daimler Chrysler 229.3, 229.4, 229.5
There's a 229.3 and 229.5, but there's no such thing as 229.4
I just checked the Amsoil website and looked up 'Product Information' for the 5W-40 European
oil, they have removed the 229.4 spec reference.
They reference the 229.3 & 229.5 specs but not the 229.4 .
Thought you would want to know.
It was confirmed by a non-Amsoil Site Supporter/Amsoil dealer that 229.4 is a non-existent spec after talking with Daimler Chrysler. It's not even a page # unless you consider 229.1, 229.3, and 229.5 as page #s rather than specs.
