I would recommend mineral oil to start with (about 500 to 800 miles) then start the good stuf. The best you can afford ( I prefer Polyol ester oil) change after 50 to 100 miles then continue. when running in be gentle and keep vairying the revs. do sitting at a constant rpm at constant load isn't so good.
I pick a nice scenic run that I would normally push it on then take it like I am doing my advanced driving test on it! good luck.
