How many kilometers can a new car drive on the highway?

[Yvette]

A new car can be driven on the highway at any time, just avoid running the engine at excessively high RPMs during the journey. New cars have a break-in period after purchase, during which they can be driven on highways as long as the engine is not operated at excessively high RPMs. Running the engine at high RPMs during the break-in period can increase engine wear. After the break-in period, it is recommended to drive the car at high speeds to enhance engine performance. This is because, after the initial break-in, the components of the engine operate more smoothly together. Driving at high speeds for a period allows testing of the engine's performance under extreme conditions and expands the tolerance limits of the components in terms of tensile, compressive, impact, and torsional resistance.
