Haven't got my car yet (although it's built and I've seen it) so haven't seen the manual. But if it's similar to the manual for the Aero 8 that I do have, it's not had too much time and effort spent on it, and is unlikely to go into much detail on oil alternatives and extra running-in precautions!
As far as I know the Morgan 3W standard is to have an oil and filter change at the 1000 miles service, but nothing before... (I might be wrong!!)
