You need to load an engine to get the rings to seat. As others have said you need to find somehow, but keep in mind that lugging it is not good because oil pressure and volume are lower at slow RPMs and could cause oil starvation for moving engine components leading to premature wear and faliure. For example, for at least the first 100 hours, if the engine can’t maintain at least 75% of the full throttle RMSs under a load, back the load off or shift down.

The importance of a load is imperative for some diesel engines (if not all) as the compression ring and piston lands are tapered in such a way that the more down pressure on the rings, the more side pressure is exerted against the cylinder wall. Thus as the load increases, the pump injects more fuel into the cylinder causing more explosive force against the rings, causing more outward force on the rings, causing them to “seat” better with the cylinder wall.

Hope this helps!
