M1 0W30 is considered a very good oil but it does seem, looking at its UOAs it does shear (significantly) in many applications. So given that this 3.6 DI engine has a known fuel dilution tendency and as also a VVT engine which again seems to be hard on oil i.e. mechanical shearing maybe M1 0W30 isnt the best here....in terms of protection.
