My car is Zhengzhou Nissan Odin cross-country, which is a diesel vehicle. Please tell me what I need for diesel car maintenance.

Whether it is a diesel vehicle or a gasoline vehicle, if the temperature is too low in winter, there will be a one-time ignition failure. This is normal. If you can't hit it many times in a row, you should check your oil to see if it is antifreeze. Generally, it is because the oil has solidified; If there is no problem, check the carburetor and electronic control system. It is relatively difficult to start a diesel vehicle. As long as you do a good job in the maintenance of the conventional parts of the engine carburetor clutch. I suggest reading more books on car maintenance. There is no need to go to 4S stores at every turn. I've always opposed this. Going to a 4S store is equivalent to buying clothes and going to a specialty store. Prices are all set globally and are very expensive.
