Royal Purple API SN does not contain moly, if that's the oil you're thinking of.
I'm not sure that I'd try 10K with it either.
If you want an oil that can go 10K, find some long OCI UOAs in that forum and see how the various oils did in engines like the one you have.
Also, what kind of driving are you talking about?
If mainly daily short trips, no oil can go 10K.
If mainly long commutes, many oils could be run for 10K.
