How Long Is the Break-in Period for a Car Generally?

[VanMichael]

During the break-in period of a new car, avoid sudden acceleration and braking. The engine speed should not exceed 3,000 rpm, and the speed on highways should not exceed 120 km/h. After running in the engine and transmission, the first oil change should be done at 5,000 kilometers to complete the break-in. Below are precautions for the break-in period of a new car: 1. Warm up before starting: This applies to fuel-injected cars. Before starting, turn the key to the second position and wait for 5-10 seconds before ignition. This is because the fuel pump starts working once the ignition is turned on, adjusting fuel pressure and injection volume. Therefore, waiting a few seconds before starting helps protect the new car's engine. 2. Avoid emergency braking: Emergency braking not only shocks the braking system during the break-in period but also increases the impact load on the chassis and engine. It is best to avoid emergency braking within the first 300 kilometers of driving. 3. Avoid overloading: Running a new car at full load during the break-in period can damage the components. Therefore, within the first 1,000 kilometers of driving, domestic cars should not exceed 75%-80% of the rated load capacity.
