Do cars need to change oil in winter?

In winter, it is necessary to change the oil with low viscosity.

Low temperatures affect the viscosity of the oil.

As the temperature drops, the oil becomes thicker, thus losing its fluidity i.e. the ability of the oil to circulate through the engine through the oil pump. Obviously, a cold and thick oil is not good for the engine to pump.

After the car has been parked overnight, and a few hours have passed, the oil will slowly flow into the oil pan, so the oil cannot be transported through the oil pump to the pistons of the engine that need the most lubrication immediately after the car is warmed, so in addition to changing the oil with low viscosity, it is necessary to warm up the engine.

Today's engine oils are all seasonal. If this is not replaced by the number of kilometers, it does not need to be replaced. Therefore, you can drive with confidence, and you can change the engine oil in 5000km or six months, and there is no problem with this.

Hello this car, most areas do not need to change the special engine oil for winter, because now the use is 5w30, the all-season common engine oil.

At present, the general models are replaced with four-season engine oil, so there is no need to change the engine oil in winter.

In winter, you only need to replace the glass water with antifreeze function, and you don't need to change the oil, and the oil is changed during maintenance.

The engine oil is universal in all seasons, and there is no need to change the engine oil in winter, but the glass water needs to be replaced with antifreeze function.

Hello, there is no need to change the engine oil in winter, and most of the current engine oils are common in all seasons.

Hello, now it is generally added to the four-season engine oil, which can be replaced if it is not needed, but it must be maintained during the maintenance period.

Nowadays, engine oil is used in all seasons, except in particularly cold areas, such as Northeast China, where it is necessary to use engine oil specifically for winter use.

Hello, if your original car uses all-season general engine oil, then it does not need to be replaced in winter, and the all-season universal model is generally 5w30.

Hello, this is not necessary to change the oil, this original is the four-season oil, and there is no need to change it.

Hello, if you are doing maintenance in a 4S shop, you generally do not need to change the oil when the maintenance interval is not reached. At present, the engine oil produced by the manufacturer is generally 5w 30 all-season general oil.

Hello, it depends on what kind of oil the vehicle originally was, if it is 5w, there is no need to replace it.

Hello, this mainly depends on whether the oil you changed last time was a four-season general engine oil, if so, it does not need to be replaced.

From a professional point of view, winter lubricating oil is divided into --18 ° is the viscosity, a total of 0w 10w 15w 20w 25w six grades, of which the smaller the number, the wider the scope of application, the summer lubricating oil is divided into 100 ° yes viscosity, there are 20 30 40 50 four grades, of which the larger the number, the wider the scope of application, the general is different in the scope of application, because the usual temperature varies greatly in various places, so in order to be economical, winter oil and summer oil are distinguished Generally, the place where you sell engine oil will tell you that the applicable range of general winter engine oil is -50° 25°, and the applicable range of general summer engine oil is.

When should the car be serviced and when should the oil be changed

The oil change is decided according to the driving environment. If the ambient temperature of the driving is relatively low, you can change the special engine oil for winter, or you can refer to the suggestions on the car maintenance manual, if you don't know very well, you can go to the 4S shop to consult, so that you can be more assured when driving, so that the car can be driven in a better lubricated state.

Attached: Misunderstandings about the use of automobile engine oil:

1. Change the oil of the car when it turns black

This way of changing the car oil is not wise, the color turns black does indicate that the car's oil has deteriorated, but now there are many engine oils will add a static decomposer, this kind of quiet decomposer can clean the black carbon deposits to form a precipitation, so there will be a phenomenon of the oil blackening, but sometimes the oil has not deteriorated.

2. Add more oil if you can

If too much oil is added, the engine compression ratio will be increased, the hidden danger of detonation will be increased, and the wear of cylinders and pistons and fuel consumption will also increase.

3. The engine oil is often added without changing

It is right to check the engine oil in time, but it is not right to only add and not change, the oil is only added and not changed, which can only meet the amount of engine oil, and cannot guarantee the use of engine oil, so this method of changing the engine oil is not correct.

There is no need to change the engine oil for the vehicle in winter, the key is to see whether the original engine oil can be applied to the standards of your safe driving natural environment and driving habits. For example, in the Northeast, it is very cold in winter, if you used summer engine oil or seasonal engine oil, it is recommended to change to winter engine oil to prevent the car from not starting, and you can also maintain the engine faster and reduce the friction of parts.

For minus a few degrees to change the cold-proof engine oil, this is not determined, most people use the 5w series of oil, and the minimum temperature available for the series of oil is minus 30 degrees Celsius, in fact, it can be applied to the vast majority of domestic regions, only in a small part of the region (such as the northeast) is more cold, it must be replaced with 0w series of oil. Therefore, the key is to choose the right engine oil for your car based on the local minimum temperature and the safe driving habits of the car buyer.

In addition to replacing the engine oil according to the natural environment, it is also necessary to replace it on time, because the oil has been used for a long time, its action characteristics will obtain the attenuation coefficient, mildew and other conditions. If the replacement is not carried out as soon as possible, the engine cannot be moistened and cleaned, and the damage to the parts in the engine will be more serious, reducing its service life and detrimental to the operation of the engine.

Generally, the replacement cycle time of full-generation engine oil is 10,000 kilometers or about one year, the application period of semi-generated engine oil is 7,500 kilometers or about 6-eight months, and the replacement period of mineral oil is about 5,000 kilometers or about one year.

Generally, it is not needed, because the oil used now can be lower than in cold weather in winter. The key is to choose a denier imitation oil model and important.

Here is an explanation of the meaning of the engine oil model silver Dayu:

For example, 0w-30

0w-30", "w" stands for "winter" which means used in winter, and the 0 in front of "w" represents the viscosity at low temperatures. "30" refers to the viscosity at 100, and the higher the number, the higher the viscosity and the stronger the ability to withstand high temperatures.

The requirements for car lubrication in winter are high, and if you are in a place where the winter is relatively cold, you need to change the winter oil.

The drop in temperature will increase the viscosity of the car oil, which will increase the running resistance of the engine, which may cause the problem of cold start in the winter. The wear and tear caused by the engine at start is twice that of normal operation, and the wear and tear caused by a cold start is equivalent to the wear and tear caused by the normal driving of the car for 150 kilometers.

During the winter months, the car changes its oil once or twice depending on the mileage. The oil selected for these two oil changes must be better than the oil changed in other seasons in order to keep the car engine running smoothly in cold weather and provide the best protection for the engine. When the weather is warmer, you can change to a lower level of oil.

The best engine oil is selected based on the SAE (Society of Automotive Engineers) viscosity index and API (American Petroleum Institute) quality grade. When changing the oil, each car owner should pay attention to the logo on the outer packaging.
