Id do the first 1000kms on the same oil.
Just change the filter due to machining waste and little bits of fluf round the engine internally.
I personally run Motul 8100 turbolight and it seems like any other...
But i am planning on changing to 300V 10-60 next change...
5000kms i believe is good for regular changes and i do the filter every 2 so 10,000km's...
I buy (forgot the brand) the filter with the magnet in it to catch any little filings and you would be supprised how much crap it will pick up.
If you decide to change oil brands or types i always do the filter also as it holds a bit of oil...
