What is the normal RPM for a new car at startup?
2 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.
I've been driving for several years, and I remember that when starting a new car, the RPM is usually quite high, typically between 1000 and 1500 revolutions per minute. Especially on winter mornings when starting the car, the engine needs to warm up quickly, so it's common for the RPM to rise to around 1500. Then, after about half a minute, it gradually drops down to an idle speed of 700 to 900 RPM. If you notice that the RPM consistently stays above 1500 without dropping or fluctuates erratically, it's best to take the car to a repair shop. It could be due to low oil pressure or a minor electronic system malfunction. Make it a habit to pay attention to the dashboard and not rush to drive immediately after starting the car. Let it idle for a while to warm up before moving—this is good for engine maintenance and helps prevent premature wear. After all, taking good care of a new car is always the right thing to do.
