From personal experience my car had a re-bore and pistons and some other work just over a couple of years ago. At running-in I changed the first lot of oil at 50 miles, then at 150 miles, 350 miles, 650 miles and 1000 miles. I change it now every 1000 miles, using supermarket 20W-50.
The amount of small debris in the first three changes was quite surprising, so perhaps an even earlier intermediate change might be beneficial. The engine has now covered 6500 miles and consumes very little oil.
