I am not sure why you said 0w-40 was not allowed for the 996tt.  That is the factory fill.

It is on the approved list. 

When it comes to oil bulletins Porsche changes them every few months. On this board is the current stuff. I have the older ones which have been superceeded.

I looked in my files for the first Boxster bulletin reference to Mobil One 0W-40 being the the factory fill for the Boxster. Issued June 1, 2001, and states the 996 turbo is an exception.

You are correct that subsequent to the Boxster bulletin Porsche issued a bulletin stating that it was also factory fill for the turbo.
