Narrative:

On a flight I experienced a dramatic loss of power and subsequently declared an emergency with approach. Approach advised that the closest airport was ZZZ. I maneuvered the airplane for an emergency landing on the grass strip. The landing was uneventful and after coming to a stop discovered large quantities of oil on the belly. The exact cause of the leak is not known at this time.
