What are the precautions for running in a new car?

[Melo]

When running in a new car, pay attention to preheating before starting; avoid emergency braking; ensure fuel quality; avoid long-distance trips and perform initial maintenance. The reason for preheating before starting is that when the vehicle is turned off, the engine oil inside will slowly flow back into the oil pan. After starting the vehicle, it takes some time for the oil to fully lubricate all parts of the engine. Avoiding emergency braking means prohibiting sudden braking. When emergency braking occurs in a new car, it will subject the braking system to a huge impact, while also increasing the impact load on the chassis and engine. Ensuring fuel quality requires using high-quality gasoline. The oil used in a new car should not be of a lower grade than specified by the manufacturer, and anti-wear additives should not be used to avoid insufficient running-in despite sufficient mileage. Long-distance trips are prohibited during the running-in period of a new car. Long-distance driving causes the engine to operate continuously for extended periods, which can easily lead to increased wear of mechanical parts. Initial maintenance is required for first-time driving. During the running-in period of a new car, frequently check whether the engine oil, coolant, and battery electrolyte are sufficient, and replenish them immediately if any are found to be lacking.
