What is the recommended RPM during the break-in period for a new car?

The recommended RPM during the break-in period for a new car is between 2000 to 2300 revolutions per minute. The initial break-in period covers the first 500 kilometers of driving, followed by the mid-term break-in period from 500 to 1000 kilometers, during which the RPM should be kept below 2500 rpm. The final break-in period from 1000 to 1500 kilometers allows RPM between 2500 to 3500 rpm. Important precautions during the new car break-in period include: 1. Avoid sudden braking and rapid acceleration; 2. Always warm up the engine before driving; 3. Avoid overloading, as carrying full capacity may damage mechanical components; 4. Avoid long-distance trips, as prolonged engine operation increases component wear; 5. Use only reputable gas stations and ensure fuel octane meets (but doesn't necessarily exceed) manufacturer specifications, while maintaining fuel cleanliness.
When I first got my new car, I was particularly concerned about the RPM. The salesperson told me it's best to keep the RPM below 3000 during the break-in period, meaning no hard acceleration or high-speed driving. For the first 1000 kilometers, I drove very gently, cruising between 2000-3000 RPM in the city and maintaining 80-90 km/h on the highway. This is because the new engine's components are still rough and prone to wear. I remember the manual also recommends doing this for the first 1500 kilometers, which not only extends the engine's lifespan but also ensures smoother acceleration in the future. By the way, avoid prolonged idling—just turn off the engine when parked. After the break-in, I noticed significantly better fuel efficiency on the highway. I'd advise new drivers to regularly check the oil level to prevent issues.
