When oil is drained, the oil filter replaced, and fresh fluid added, a certain amount of air remains in the oil galleries and oil pan. The Science Behind the Break-In Modern engines are精密 machines where tolerances are measured in microns.
Automotive Engineers Engine Break In Oil Change Process and Best Practices
Maintain this speed for 30 seconds to agitate the oil and purge air from the system. Cold oil is thicker and flows more slowly, which can make the purge process less efficient.
The engine break in oil change facilitates this purge by allowing the vehicle to idle and run at a low, safe RPM. An engine break in oil change is a critical procedure often overlooked by drivers who assume any fresh oil will suffice.
