What is the break-in period mileage for the Infiniti QX50?
1 Answers
The break-in period for the Infiniti QX50 is 3,000 kilometers. Before vehicle assembly, each moving component is processed separately, and geometric deviations exist during the machining of parts. Therefore, after assembly, some moving parts may have direct local contact, making it difficult for lubricating oil to reach the friction surfaces, resulting in early wear. The process of wearing away metal debris and burrs from parts when the car is first used is called the break-in period. Below are precautions to take during the new car break-in period: 1. Avoid high-speed driving: New cars have speed limits during the initial driving phase. Domestic vehicles are generally limited to 40-70 km/h, while imported vehicles typically require that within the first 1,000 kilometers, the speed should not exceed 80% of the maximum speed when the throttle is fully open. Additionally, it is important to monitor the engine tachometer and speedometer to ensure the engine and vehicle operate at medium speeds. Generally, the engine speed during the break-in period should be strictly maintained between 2,000 and 4,000 rpm. 2. Throttle and brake usage during the break-in period: Learn to control the depth of the throttle during the break-in period. Pressing the throttle deeply increases air intake, which in turn increases fuel injection, potentially damaging internal components. Frequent hard braking can also cause excessive wear on the braking system. 3. Avoid emergency braking: Emergency braking not only shocks the braking system during the break-in period but also increases the impact load on the chassis and engine. Therefore, it is recommended not to use emergency braking within the first 300 kilometers of driving.
