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

[McJustin]

During the initial break-in period, keep the engine RPM between 2,000 and 2,300. In the middle phase, maintain it below 2,500 RPM, and in the later stage, control it between 2,500 and 3,500 RPM. The vehicle's break-in period is essentially a gradual process - slowly conditioning and progressively increasing the car's speed allows for optimal engine performance development. Throughout this period, avoid both excessively high and excessively low engine RPMs. For manual transmissions, refrain from maintaining a single gear for extended periods. Additionally, don't overload the vehicle during break-in as this may cause engine wear, and avoid prolonged continuous operation to allow the machinery proper adjustment time.
