Tips for running-in period of automatic transmission new cars include: 1. Pay attention to the running-in mileage: The running-in mileage of a new car is generally 1000 to 3000 kilometers, and the engine speed can be increased to 3000 rpm. To keep the new car engine active, avoid high-speed operation of the engine while driving, and the lower the speed, the better, otherwise it may damage the engine; 2. Pay attention to warming up the car: Do not start immediately after starting the car, wait until the water temperature reaches the normal temperature before starting; 3. Pay attention to changing the speed: Do not maintain a constant speed for a long time. Automatic transmission cars cannot determine the gears that need to be run-in like manual shifting, so it can only be achieved by constantly changing the speed; 4. Do not run-in with heavy load: During the running-in period, try to drive with an empty car or small load, and do not overload; 5. Check the equipment: Before driving, check all the meters to see if they can display the normal functions of each part.
I just bought a new automatic car and feel that the break-in period really requires attention. Remember not to exceed 80 km/h for the first 1,000 kilometers, avoid sudden acceleration or hard braking, as these can be harmful to new engine components. New drivers tend to be impulsive, so I always remind myself not to press the gas pedal too hard—keeping the RPM around 3,000 is safest. Also, avoid carrying too much heavy cargo; don’t overload the trunk, as it’s better to travel light. Automatic transmissions are convenient, but during the initial period, it’s good to use cruise control more often to maintain steady speeds. I recommend checking the engine oil monthly, as fresh oil lubricates the components better for smoother break-in. Honestly, developing good driving habits during this phase pays off in the long run with better fuel efficiency and longevity. Sometimes, I even take slightly different routes on longer drives to vary the speed a bit, helping to smooth out internal engine imperfections. In short, drive gently and avoid impatience.
