Nothing happens, so it is like it wasn't run at all. Too much of it, though, and it will wear just enough to prevent a true break-in. 5 hours is kind of a long time, so I would wait and see. After 5 hours of hard running if the oil consumption stays high (a quart every hour or two) then I'd start to think something wasn't put together right. On one of my engines I found an intake valve guide that was loose in the head, for example.
