I'm wonderin this as well. I went with the recommended interval for my second oil change - after the 1200 mile service, I did not change the oil until the car told me it was due at 15000 miles. Hope the potential long term damage is not too bad. I'm definitely doing an oil change every 7500 miles from now on.
