I agree with whatever is said about need for timely maintenance. Compression is good, engine is running and some oil did drain out. If it were me I would put quality synthetic oil and do couple short interval oil changes and gradually increase oil change interval. You would be surprised how clean the engine would get without tearing it down and cleaning it after few oil changes.
