How Should a New Car Be Run In?
1 Answers
New car run-in methods are as follows: 1. The most crucial aspects of running in a new car actually serve two purposes: first, to achieve harmony between the driver and the car, and second, to ensure proper integration of the car's components. 2. Starting with the correct engine startup procedure, always wait for the self-check to complete before starting the engine, and avoid immediate ignition. The primary rule of running in a new car is to constantly monitor the dashboard's warning lights and address any unfamiliar fault indications immediately. 3. Regarding engine run-in alone, the engine has already undergone low-speed and high-speed adjustments during assembly, which is why some cars claim to require zero-kilometer run-in. However, since the car's powertrain involves many aspects, it is still recommended to properly run it in, but avoid high-speed operation too early. 4. For the first 2,500 kilometers, it is advised not to exceed the following speeds in each gear: 1st gear - 20 mph, 2nd gear - 40 mph, 3rd gear - 60 mph, 4th gear - 80 mph, and 5th gear - 100 mph. The main goal is to ensure smooth engagement of the new clutch, proper meshing of gears in the transmission, and smooth power delivery. 5. However, it is important to avoid continuously using a single gear for extended periods to prevent excessive heat buildup in that gear set, which could lead to uneven heating inside the transmission. This may cause metal shavings to form when shifting gears due to meshing issues.
