Breaking in a new car...A 2019 ford fiesta se hatchback

The thing is when someone recalls something that someone said, it may not be very accurate. You know input/output. At any rate my Acuras, and maybe other cars or small engines, (I just can’t recall but read the owners manual) have said that they contain “break in oil” and not to change it until the specified time. I don’t know what is in the mix of oil from the factory, but that may have been what the guy meant. I always do my first oil change earlier to get that stuff out of there but I usually check with the service department before changing out the break-in oil. My pressure washer for example is two years old but still doesn’t have the required run time to change the original oil. Maybe I should check for grit when I change it.
