As posted in other threads Pennzoil Platinum has been removed from the approved dexos list. I emailed Shell today with a question as to the future of Pennzoil synthetics and the dexos specification. Here is their reply:
Dear Consumer,
Thank you for your inquiry. Unfortunately, the plan is not to re-certify our Platinum and Ultra brands. You can also consider using our Quaker State Ultimate durability 5W-30. That is a full synthetic and does have the Dexos approvals.

Technical Service, sn
So looks like the approved SOPUS list for dexos is getting mighty short. Makes me wonder if I should just go ahead and switch to M1 as they've historically always had a good relationship with GM. I'm wondering how much longer SOPUS will pay for QSUD to carry the certification?
I know they are all good oils, but I don't want to fight GM if I ever have an engine/oil concern under warranty.
