First, check the car engine.
Inspection items: antifreeze, freezing point and lubricating oil label of water tank.
At present, there are special engine oils for winter on the market. Generally, you only need to find the packaging of oil drums, and the logo representing the special oil for winter will be marked with "W", such as 0W, 5W, 10W, etc. For example, 0WW shows that even if the temperature drops to -30℃, the lubrication and flow of oil can still be maintained in a good state. In short, the smaller the number before W, the better the startup in low temperature environment.
By the way, on the contrary, there is high temperature when there is low temperature. In high temperature environment, the viscosity grades of engine oil are SAE20, 30, 40, 50, etc. Similarly, the higher the number, the better the effect.
Second, parking knowledge
Car windows are prone to frost in winter, which is really a headache. This is because the temperature difference between inside and outside the car is unbalanced. The solution is to open the window for a period of time before parking, so that the temperature difference between inside and outside the car is in a balanced state, reduce the temperature inside the car and improve the frosting of the glass.
In fact, the best way is to park your car in the garage or underground parking lot. If you can only park outdoors, you'd better choose some dry, flat and sunny places (there is no water, and the tires are easy to freeze in winter) and then park your car in the leeward, so that the stimulation of snow and snow to the engine will be reduced to some extent.
If there is a certain slope in the parking position, it is recommended that the front of the car go uphill, otherwise the condensed water will flow backward into the exhaust system.
Third, the aspects that began to pay attention to
In winter, in order to avoid ignition difficulties or flameout, you can change the starting time to 5 seconds, and try again in a few minutes after not starting several times. If you want to maintain the battery in winter, friends who don't bother can take it down and put it at home, and then install it before driving. Then start the car or pay attention to the hot car for one minute and then drive at a low speed.
