What is a car break in period?

The break-in — or mechanical run-in — period is designed to begin to wear the engine evenly and smoothly with low, consistent pressure, normal operating temperature and smoothly flowing oil. The goal is to get the engine’s piston rings, which expand, contract and flex, to seat properly on the cylinder walls.

How important is engine break-in?

Breaking in an engine ensures that early engine wear is kept to a minimum, and that the oil flows smoothly and evenly through all moving parts. It also gives the piston rings (the connector between the cylinder and the piston) time to seat properly, and allows the engine and transmission time to adjust to each other.

Is break in oil necessary?

Break-in oil is a critical component of an engine rebuild. It allows controlled friction in low-load areas like piston rings. … This ensures that all surfaces within the engine are fully mated, particularly the piston rings and valvetrain. A proper break-in is vital to a successful build.
