Why does Nissan have the first insurance at 2,500 kilometers?Nissan first warranty does not need to change the oil

The machining of Japanese engine parts is relatively smooth, and the assembly clearance is also very tight. Secondly, according to the machining accuracy of Japanese engines, the running-in period of 2,500 kilometers is completely sufficient. Too late first maintenance is just to cause bad wear to the engine by iron filings.So, generallyNissanCompared with other car series, the first insurance time of the car will be much earlier. The first insurance can be done after 2,500 kilometers, and generally not more than 3,000 kilometers.

General vehicle first maintenance items include: replace the engine oil and oil filter, clean the air filter, check whether the tire pressure is normal, check the chassis and all the switches of the whole vehicle, check whether the various oil levels are normal, check whether the tire pressure is normal, check the generator belt,wiperswhether the chip is damaged.

The first warranty requires an oil change. The first warranty period of a new car is the running-in period of the vehicle. Although the new car has been run-in after leaving the factory, the surface of the parts is still rough.In addition, there will be certain deviations and some difficulties in processing and assembling.Discoverhidden dangers, etc., and there will be a lot of metal particles falling off between new parts and accessories. These metal particles will not only aggravate the wear between parts, but if they fall into the engine oil, it will also reduce the quality of the engine oil and affect the lubrication effect. Since new parts have greater frictional resistance than normal during operation, fuel consumption will also be higher. Therefore, the first guarantee is to replace the engine oil and oil filter, otherwise the performance of the engine will be seriously affected.
