I have 1300 miles on mine and I am overdue for an oil change.
Returning my top-grade FRAM and going all the way to subaru to get a subaru filter has held me up....
I feel the first one is important to do... Your oil really can get bad during break in period.... I feel it's important to change it before i bring it to the track...
GTX for this change, then probably to mobil 1.
