Winter car maintenance is easy to enter the misunderstanding

The car is the preferred means of transportation for modern people, and the car owners spare no effort to care for it. In the face of cold winter car maintenance will also go astray, especially when you are anxious to love the car but the maintenance error often occurs.

In order to keep warm, some car owners always put the air conditioning switch in the position of internal circulation, in fact, this way is somewhat inappropriate, and the adjustment method of air conditioning should be determined by temperature and environment. After starting the engine, after a few minutes of good operation, first open the blower, and open the window for ventilation, and then open the air conditioner when the temperature in the car drops slightly to reduce the load of the engine and compressor; first use the circulation in the car to quickly cool down the air, after driving for a period of time, the temperature inside the car is roughly the same as the ambient temperature outside the car, and then use the external circulation to keep the air in the car fresh.

Some car owners think that cheap is not good, so when choosing lubricants, they feel that the more expensive the better. In fact, there is another sentence corresponding to it, called the suitable is good. Choosing the right lubricant for your model and season is the right thing to do. Good lubricants are selected according to SAE viscosity level and API quality level. Take "SAE10W-40" as an example: SAE refers to the viscosity level, W refers to the oil suitable for winter, the smaller the number in front of W, indicating that the lower the low temperature fluidity of this lubricating oil, the better the lubrication at cold start; the numbers behind 10, 20, 30, 40 and so on refer to the size of the viscosity, the larger the number, the higher the viscosity of the high temperature.

In winter, because of the cold weather, some drivers feel that the preheating start is troublesome, so they use open fire roasting car start, suction start, waterless start, slope start, drag start, cart start, etc., which aggravates the wear and tear of tires, drive train, engine friction, and can lead to broken shafts, cylinder pulling, flying car and other failures, and when serious, it will also cause crashes and overturning accidents. In fact, there is also a simple hot car method, the engine starts 30 seconds to 1 minute after driving on the road, pay attention to the gear control at 1-2 gears, the engine speed is maintained at 2000 rpm. After driving for a few hundred meters in this way, after the engine temperature rises back to normal levels, the owner can accelerate normally, which can also reduce the engine damage.
