Back in The Good Old Days, doing the first oil/filter change at 500-1500 miles could make a big difference in engine life. Even today, it's a good idea if you want to get maximum longevity. But for most people, with modern manufacturing processes and lubes, it's just not that big of a deal (at least with a DD). Since you care enough to ask, I'd go ahead and change at 1000-1500 miles, but waiting until 3750 or so will not really hurt. Keep an eye on the oil condition and change if anything looks "funny."
