Has the break-in period passed at 1500 kilometers?

[MacJourney]

1500 kilometers marks the completion of the first phase of the break-in period, which is a fundamental process to ensure full contact, friction, adaptation, and stabilization of mechanical components. During this phase, the vehicle's parts can adjust and enhance their ability to adapt to the environment, while smoothing out any protrusions on the components. The quality of the break-in period significantly impacts the car's lifespan, safety, and fuel efficiency. Key considerations for new car break-in include: 1. Avoid idling to warm up the engine; 2. Do not drive at high engine RPMs; 3. Prevent excessive engine load; 4. Refrain from changing the original engine oil prematurely during the break-in period, and regularly check the levels of engine oil, coolant, battery, and electrolyte, topping them up immediately if low; 5. Replace the engine oil and the three filters (fuel filter, oil filter, air filter) as well as gear oil at around 2300 kilometers into the break-in period.
