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.
Probably as simple as the person doing web stuff knows bugger all about oil and thought if theres 229.3 and 229.5 logical to assume theres a 229.4 as well.
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.
