Do modern cars no longer have a break-in period?

[VanJayden]

New cars do have a break-in period, but generally, modern vehicles do not require special breaking-in procedures during this period. Below is relevant information about the car break-in period: 1. Break-in period: The break-in period refers to the time from when the car is purchased until its first maintenance service. During the break-in period, aggressive driving is not allowed, and cars that support launch control should not use this feature. Avoid running the engine at excessively high RPMs during the break-in period, as this can accelerate engine wear. 2. Break-in oil: The oil used when the car leaves the factory is initial fill oil, which is suitable for use during the break-in period. This initial fill oil should not be drained prematurely nor used for an extended period. For the first maintenance, it is recommended to visit an authorized dealership and use the manufacturer's genuine oil.
