How many kilometers should a new car run at high speed?
2 Answers
New cars should run about 10 kilometers at high speed. Pay attention to gear shifting, speed control, and clutch usage during high-speed driving. Precautions for using a new car include: 1. Maintain smooth starts, avoid sudden acceleration, and do not let the engine speed get too high; 2. Before starting, the water temperature should reach above 50 degrees Celsius, start in a low gear, and shift to a high gear after 1 kilometer; 3. Shift gears promptly while driving, avoid using one gear for a long time, and do not use a high gear at low speed or a low gear at high speed. A new car is a vehicle that has just left the factory and passed road tests, with a factory time of no more than six months.
When I first got my new car, I was also confused about this and asked an experienced technician at the 4S dealership. The so-called 'running-in at high speed' doesn't actually refer to the vehicle's speed, but rather focuses on the engine RPM. After the initial 1500 km break-in period, find a highway with good road conditions. For manual transmissions, downshift to increase RPM, or for automatics, switch to S mode to raise the RPM to around 4000. Maintain this for 15 to 20 minutes – no need to foolishly speed over 160 km/h, which is both dangerous and harmful to the car. Remember to get the first oil change promptly after this procedure to remove any metal particles generated during break-in. Last week, I accompanied a friend for this high-speed run, deliberately choosing the early morning hours with lighter traffic, and the results were quite good.
