Too early! There's not enough time for the engine to wear in. Generally, the first oil change rids the fluids of high concentrations of break-in wear metals. I wouldn't recommend doing it so early. Maybe if you did all city driving and varied your rpms it would be okay. You might want to do another oil change on your own at 3,000 or 5,000 miles to clear the engine oil again. However, in the long-run, it probably shouldn't make a huge difference if any at all.
