Rings seated at 550 miles? Probably. But my advice is follow the OM break-in recommendation. Remember, it was Nissan engineers who designed the engine and know what is required for a proper break-in and not a bunch of opinionated yahoos on the internet who may or may not know the difference between a piston ring or an engagement ring. Just my opinion.
