Based upon my first 5 UOAs, I would say that 1000 miles is about right for the first OC with another about 3500 after that (or 4500 total miles), then settle into a normal OCI. There was a fair amount of copper, iron, and silicon that was shed during the first 1000 miles, but had dropped off by 10,600 total miles.

If I may--the regime that you suggest is too excessive and the one that I did may be considered by some to be excessive, and some may argue to wait and capture all of the wear metals in one fell swoop, but there is empirical evidence that extra wear metals exist in the early OCs. Now, whether or not they cause more engine wear remains to be seen, but I believe I did the right thing for the long run.
