What is the recommended speed during the break-in period?
2 Answers
The speed during the break-in period should be controlled at around 70 to 80 kilometers per hour, with the engine speed not exceeding 2200 rpm. The break-in period refers to the initial driving phase of a new car or after a major overhaul, typically covering 1000 to 1500 kilometers. This is the essential mileage required to ensure that mechanical components fully contact, rub against each other, adapt, and settle into their final form. During this period, the car's various parts can adjust and enhance their ability to adapt to the environment while wearing down any protrusions on the components. After driving more than 1500 kilometers, you can gradually increase the engine speed and vehicle speed to the maximum allowed by the car. Avoid pressing the accelerator pedal forcefully to ensure that pistons, cylinders, and other critical components increase their load under moderate conditions. Additionally, avoid using a single gear for extended periods. Start in a low gear and progressively shift to higher gears, driving in a step-by-step manner.
When I first bought my new car, I kept the speed between 60 to 80 km/h during the break-in period for optimal stability. I remember on the day I picked up the car, my friend who works as a mechanic repeatedly reminded me not to drive too fast and to keep the RPM below 3,000 to avoid excessive wear on engine components. For my daily commute, I usually maintained around 70 km/h, and even on the highway, I gently pressed the accelerator to avoid sudden acceleration or braking. The break-in period isn't just about speed—it's also important to avoid overloading the car, ensure proper tire pressure, and follow these practices to extend engine life and improve fuel efficiency. After two months of careful driving, I noticed the car's responsiveness became smoother, and overall performance improved significantly. I recommend all new car owners take this phase seriously and consult the manual—don't skip this step.
