I've put near 300000 miles on several engines.
Technically there is no reason to change oil prior to the first oil change reminder, which will occur somewhere between 3500 and 8000 miles, unless it takes you more than a year to put those miles on. I'd wait till the second oil change before switching to synthetic.
Changing early is an old wives tale, like changing every 3000 miles. But it does make some here more comfortable. Something about cleaning the sand out of the casting... but after 100 miles that grit has already done its damage or has been caught in the oil filter. So do what makes you feel good.
