I agree regarding SN synthetics but I'm not sure that most blends would meet dexos1 requirements.
Mobil 1, QSUD and PP are all dexos1 approved (which means they pay GM the licensing fee).
Castrol Edge Syntec says it meets dexos1 but it isn't licensed (because they won't pay GMs fee). I think Valvoline Synpower is in the same catagory as Edge w/Syntec.
My new Cruze 1.4T calls for dexos1 and I think that any name brand synthetic should work. I wouldn't worry about using synthetic in the non-turbo 1.8 Cruze but I feel better using synthetic in a turbo.
As far as filters I think the AC, Wix and even Fram are all capable of doing a full OCI safely.
PS: I'm thinking of picking up some (non dexos1 approved) Shell full synthetic at BJs or Napa full synthetic which are both great deals right now.
Which of these two oils would be better?
