As I type this, your signature shows that you're using T5 15W40. So far they have only reformulated the 10W30 (speaking of the T5). Just sayin' so if you're interested in a voa of the CK-4 (15W40) version, you may need to wait.
The T5 15W40 doesn't list much of anything on the approvals list. A few are on there but I'd prefer the oils with a long list of approvals.
