I wouldn't worry much about d1g2. I think any API SN+ synthetic, in the appropriate viscosity, would qualify for d1g2 if the blender cared to apply (and pay) for certification. Pennzoil, Amsoil, whatever, as long as it's API SN+ synthetic in the appropriate grade, I don't see how you could go wrong. I believe DEXOS is just GM's way of migrating their customer's oil change habits from conventional to synthetic.
