2000 miles on engine? Barely, if, broken in. Aircraft engines are considered broken in when oil consumption stabilizes. Between 5-10 hours at 75% rated power at lower altitudes for best cooling. Cars could be considerably longer since it’s hard to keep 75% power.
I will reiterate, most of the people on these boards simply don’t drive their cars enough to keep them healthy. Bearings sit metal to metal, oil oxidizes, heating and cooling cycles cause moisture condensation/collection. Add washing repeatedly, then waxing traps water in crevices and low areas. The simple act of driving mixes all the stuff up, airflow dries things out and redistributes the lubes and oils.
I have pulled cylinders off of aircraft engines that had the rings corroded to the cylinders, rusticles hanging from the cam, dripping into the sump.
The main byproducts of internal combustion are CO2 and H2O along with a few other compounds. Every single engine that has run has water in some amount inside.

My car isn’t “happy” until it’s temp is up and 20-30 miles are under the tires. Everything smooths out and settles in. But I average 1000 miles a month, rain or shine.
If you are worried about date codes on your tires, wear them out, problem solved. The simple fact that there is so much concern for date codes prove they aren’t driving enough.
Drive it, like the good Dr says.
