I think you should have took better notest Ed. they originally said you should change your oil at 600 miles. They've relaxed that 1000 +or - a few hundred miles. if you're not running the car hard a few extra miles either way shouldn't hurt anything.I was told by my delivery specialist that first oil change is at 5K miles unless you take it on the track. If you go to the track change oil before the event.

The normal service intervals are 5,000 miles of normal driving or 2,500 hard driving at the Track etc.. I would not do my first oil change at 5000 miles.
With this expensive motor I don't think you'd want to wait no matter what they told you
