How long is the break-in period for a new car?
2 Answers
New car break-in period requires driving more than 5,000 kilometers, generally taking about 1 year to complete. Below are relevant explanations: 1. Definition of new car break-in period: The break-in period refers to the initial stage of a new car or after major repairs, also called running-in. 2. Reasons for new car break-in: Although factory-new cars have undergone initial break-in, the surfaces of components remain relatively rough. Additionally, there are certain processing and assembly deviations along with some hard-to-detect potential issues. This mileage ensures full contact, friction, adaptation and final shaping of mechanical components. During this period, it can adjust and improve each component's ability to adapt to environmental conditions.
Actually, there's no fixed rule for the break-in period of new cars nowadays. Last year when I bought my SUV, I specifically checked the manual, and the manufacturer recommended avoiding hard acceleration for the first 1,600 kilometers. The main point is to prevent the engine from running at high RPM for extended periods, and try not to exceed 100 km/h on the highway. The brake pads also need a break-in period, so it's safer to apply the brakes gently for the first 300 kilometers. A friend at an auto repair shop mentioned that although car manufacturing technology has advanced, the transmission gears still require a break-in period, especially for manual transmission models. For the first month, I basically kept the RPM below 3,000 and regularly checked the engine oil condition. Now, it feels particularly smooth to drive.
