What is the process to run-in new piston rings? Using the standard synthetic or semi-synthetic oil is unlikely to do the job. Has anyone had any experience of doing this?

I heard that the factory use a special oil and run the engine on a dyno to run it in.

    The factory uses Aeroshell Sport +4 10w-40.
    No special oil is needed and no break-in procedure is specified for ring replacement.
    Just don't lug, or baby, the engine.
    During assembly: DO NOT use moly or any other coating on the piston or cylinder walls. Only a film of motor oil is needed.
