Are you an engine builder?
Switched to synthetic at a conservative 2000 miles on the Z, much like I switch to synthetic right at 1200 miles on all my built turbo engines... hasn't burnt a DROP since switching.
It's safe to run the VHR on synthetic out of the box, if and only if you break it in aggressively. Mobil 1 comes as factory fill on many cars - Corvette, Evo's, Mercedes AMG (I believe)...
