AIUI the engine management system monitors the quality of the oil as well as the amount. When I changed it, the oil looked as though it had been there for a while and was quite thick/dark (last serviced at 100hrs, 173hrs on it now. I've only put 10 hours on it and I don't know what use/standing the engine had done with the previous owner).
So I'll take it for another test run soon and then just keep a watchful eye til I service it in 25ish hours.
