I would expect the schedule for the first $X months/$Y km to differ from subsequent periods. Manufacturing tolerances are incredible these days but there is still going to be a period of high wear leading to less and less new particulate in the fluids. At some early point, months if not weeks or days after the mechanical bits all have experienced a range of conditions, a fluids change would be beneficial. Most of the wear having taken place, it will take much more time to reach the same level of contamination after the first fluids change. Does your owner’s manual recommend abiding by certain speed/rpm limits during a break-in period? I’m pretty sure my (Canadian) old car/old truck do.
