What is the normal RPM for a new car at startup?
1 Answers
New cars typically have a startup RPM around 1000. Since the new engine hasn't been broken in yet, the starting resistance is higher, resulting in a correspondingly lower startup RPM. After the engine has undergone proper break-in and maintenance, the coordination between moving parts reaches its optimal state, and the RPM may increase slightly. Below are some precautions for breaking in a new car: 1. Avoid overloading: During the break-in period, the vehicle's load should not exceed 75% of its rated capacity. New cars should be loaded below the specified weight and passenger limits, and overloading must be avoided. Overloading increases the burden on components such as the engine, transmission, drivetrain, and suspension system, accelerating wear. 2. Generally, domestic vehicles should not exceed 75% of their rated capacity, while imported vehicles should not exceed 90%. Additionally, to reduce the load on the body and powertrain, choose relatively flat road surfaces and avoid vibrations, impacts, or emergency braking. 3. During the break-in period, the gasoline used in a new car should not be of a lower grade than specified by the manufacturer. Do not add anti-wear oil additives, as this may result in insufficient break-in even after reaching the required mileage.
