Several ring manufactures agree totally with run them hard as soon as possible to get enough cylinder pressure to seat the rings, but no excessive rpm. I believe one company said with a manual trans to go from 30-60 in high gear at full throttle somthing like 20 times,then drive the engine like you normally would with no long runs at a constant speed. No baby treatment. I had one tractor with an L10 Cummins that I ran on a light load for the first 30 or so hours,the thing was an oil hog and must have had a lot of ring blow by as the oil got black very fast. Cummins replaced sleeve/piston/rings assy and told us to pull the heck out of it as soon as the water temp hit normal. We did that and had much better luck the second time.
