Do cars still need a break-in period nowadays?

[DelLaura]

Currently, vehicles still require a break-in period, albeit a shorter one. Here are detailed explanations about car break-in: 1. Overview: The break-in period generally refers to the process where mechanical components initially come into contact, rub against each other, and mesh during early operation. It is often used to describe the time when two things or internal operations within an organization become familiar and adapt to each other. 2. Purpose: Break-in is also called run-in. The car break-in period refers to the initial driving phase of a new car or after a major overhaul, typically covering 1,000-1,500 kilometers. This is the essential mileage required to ensure full contact, friction, adaptation, and stabilization of mechanical parts. During this period, the vehicle's components can adjust and enhance their ability to adapt to the environment while wearing down any protrusions on the parts. The quality of a car's break-in will significantly impact its lifespan, safety, and fuel efficiency.
