Well I spoke to a couple of dealers and they are adamant that the car comes to OZ with full synthetic from the factory. They also both said that the car doesn't really require a running in period and to drive it as normal after 500kms just so that your familiar with it and the tyres, brakes etc are all set in...
They recommended the Nissan synthetic that they sell (or course!) and one also recommends Mobil 1 - they both say that the car HAS to have full synthetic 5W 30 and that I shouldn't bother changing the factory oil until at least 5000 as its a waste of money.
I might still change it anyway since I brought the oil - plus it will be good get the tools out and my hands dirty for a change!
