Is Driving a New Car at 120 km/h on the Highway Harmful?

[McBrody]

Driving a new car at high speeds on the highway can be harmful, and it is not recommended unless absolutely necessary. If you must drive a new car on the highway, avoid staying in one gear for extended periods. Change your speed and gear every few minutes to allow all gears to break in evenly and reduce excessive wear on any single gear. Additional Notes: 1. Gearbox Control: Just like the internal components of the engine, the parts inside the gearbox also need to break in. Shift gears frequently to ensure all gears are properly run-in. Driving on various complex road conditions can help. For manual-automatic transmissions, it is advisable to switch between manual and automatic modes often. 2. Avoid Emergency Braking: During the break-in period, frequent hard braking can cause uneven wear on the brake pads, leading to issues like noise and vibrations, as reported by many car owners. These problems may stem from improper break-in practices. Typically, within the first 300 kilometers, try to avoid emergency braking as much as possible.
