But there is this statement that I don't agree with, and I really dont think any other engine builder would agree with either. To me, this statement says that after rebuilding an engine, run it with the oil for 10k miles. Is this excluding the 500 mile "break-in" (yes, I do realize the engine is not completely broke in at 500 miles) period? Or is it stating that you don't need to change it at 500?
