Good news, this is first verification I have seen the PUP 0w40 has lowered CA level specifically for Hurricane engine. It seams to be a little lower total tbn formula so it appears to be a lower interval oil, which is how it should be because you don't want to run long oci's in a di turbo and no reason for extra tbn when the oil should be out of the sump at 5k miles. This oil at a 5k interval looks like what the doctor ordered for the hurricane.

The rumor is the SO has a low viscosity, I have no comment on that one. I can say PUP 5w30 has already done this to that formula long ago as it is SP category which means ok for di.
