That's right. For first ~500 miles after oil change. Hence, oils with HBN does not exist. Solid lubricating components can't be added in the plant therefore. Why ~500 miles? In the time the new oil solves old filth from the previous oil. Thereafter this is no longer so important. And for safety of solid components, dont overdosage. Overdosage is (IMHO), more than 1%. With 1% after 500 miles you are safe. Guarantees. I am using HBN in many cars since 500.000 miles (accumulated to all cars in the family)
just say no to solids of any type in the oil IMO.
