Adding oil to new Z?

I am usually driving around at 2500 to 3000 RPM most of the time with some bursts to around 5000 RPM. I don't sprint away from a stop. Just curious why I should change oil now plus at 5000 miles? My local dealer uses Mobile 1 which I will change over to at the first oil change. Is this a good oil to use or is something else better? Thanks
