The cold air continues to exert force, the temperature plummets, many car owners and friends are anxious to protect the car, but they have stepped on the misunderstanding of winter car maintenance
1.Blindly change low-viscosity oil.
The lower the viscosity of the oil, the thinner the oil, and the better the fluidity of the oil at low temperatures, so the oil with low viscosity can lubricate the engine parts faster, which has a certain protective effect on improving the friction and wear of the vehicle during cold start. However, if the viscosity of the replaced oil is too low, and the oil film is not enough to support the shear force of the engine during normal operation, it will lead to poor lubrication effect, oil film rupture, and even dry friction and engine cylinder pulling. Moreover, the current engine oil technology has been relatively mature, as long as the brand oil purchased through regular channels, it is generally common in all seasons, especially the fully synthetic engine oil of Dihang with superior performance, which does not need to be replaced according to the change of seasons.
2.Mix with antifreeze.
In winter, when the temperature is low, it is necessary to protect against freezing. The antifreeze, anti-boiling, anti-corrosion, anti-rust, anti-scaling, and anti-foaming functions can protect the cooling system from freezing and cracking, and can also avoid the high temperature alarm of the engine. However, some car owners only know to add enough antifreeze without replacing it, or even mix different brands of antifreeze, which is not right. Different brands of antifreeze have different formulations and freezing points, and random mixing may cause chemical reactions of the ingredients, which may form sediment, affect the effectiveness of antifreeze, and clog the water tank pipeline.
3.The hot train takes too long.
It is said that hot cars cure all diseases, and they must be heated in winter, but many people have the wrong way to warm up cars. In fact, the time to warm up the car in winter should not be too long, otherwise it will not only increase fuel consumption, but also increase the carbon deposit of the engine, which will bring about problems such as unstable idling of the vehicle, excessive exhaust gas, and difficulty in starting, the correct way to warm up the car should be to start the car for about 30 seconds to start low-speed driving, and then drive normally after the water temperature is normal.
If you have a similar operation in front of the screen, you must pay attention to avoid it, which seems to be a good behavior for the car, which may cause more harm to the car.
