What kind of engine oil is good for cars in winter, and what kind of engine oil is better to add in

It's not about looking at the brand, you have to look at the label.

10W-40 is its SAE standard viscosity value, this viscosity value first indicates that the oil is a re-grade lubricating oil (now there is basically no single-stage lubricating oil in the civil field), W stands for Winter winter, and the number in front of W represents the pour point temperature, which is simply the freezing point temperature. The corresponding freezing point temperature of 10W oil is -25, other common 0W is -35, 5W is -30, and 15W is -20. The number after w represents the kinematic viscosity of the oil at 100, and the higher the value, the higher the viscosity.

Now you can choose the right oil for your local temperature.

It needs to be replaced, and the oil change is generally determined according to the number of kilometers and time, and the suitable oil needs to be selected in particularly cold places.

Boss, I've served you, Fox engine oil generally needs to be replaced in 5,000 kilometers or 3 months, if you add blue shell or gray shell, you can consider 10,000 kilometers and then replace, in addition, which city are you driving in? It's best to ask specific questions.

Of course it has to be changed. The number of kilometers is enough to do maintenance. What season is used for what oil, and still have questions?

The engine oil is changed once on the 5000 road, you are talking about changing it in summer and changing it in winter, what a headache!! You don't need to change it once in the first quarter.

In winter, when the temperature is low, it is recommended to change to a fully synthetic engine oil, and the starting number should be smaller.

Because the temperature in winter is still very low, the requirements for the low temperature fluidity of the engine oil are very high. It is best to use an oil with a grade of less than 5w, which can effectively prevent freezing. Winter engine oils generally have a W mark oil type.

The number in front of w represents the low-temperature fluidity of the oil. The lower the number, the lower the freezing point, the more resistant to low temperatures, and the better the flowability.

Change the engine oil in winter, the cold engine oil is affected by low temperature, and the fluidity becomes poor, which will cause the old engine oil to be unclean. When the oil reaches a certain temperature, the lower the viscosity, the higher the fluidity, and the sludge inside the engine will also soften, which makes the softened sludge drained together like old oil, and now it comes out, and the oil is drained faster to improve work efficiency.

Also make sure that the old oil can be put away more cleanly.

However, it is necessary to pay attention to the amount of engine oil lamp oil to avoid oil leakage after the liquid level rises and the car is cold. There are two types of oil leakage: internal leakage and external leakage. An oil leak is an oil leak from outside the engine, mostly due to certain oil seals.

damage. The solution is to check the oil leak and replace the relevant oil seal. Internal leakage is more troublesome, oil leakage into the combustion chamber combustion, the amount of oil will be reduced, at this time the car must be overhauled, otherwise it will reduce the engine power, greater pollution to the environment.

In winter, when the oil is changed in the current month, the temperature changes in the area are observed. For example, the winter in Guangzhou begins to cool down in November, while parts of the north may begin to cool down in September. Therefore, the time to change the engine oil in winter should ultimately be decided according to the actual situation.

Don't underestimate this problem, not to mention that it doesn't affect the performance of the oil, it's just that starting the engine is already difficult.

If it is below zero and below 10 degrees, it will cause the effect of the oil to be lost. In the long run, it is easy to experience severe engine wear and tear, and maintenance costs are not low. So be sure to pay attention to the local temperature changes before buying, if it is in the southern region of Guangzhou.

The temperature in winter must not be lower than minus 10 degrees, so you can use it with confidence at this time. But if it is in a cold place with a cold winter such as the north, it is necessary to change the engine oil with more cold resistance.

You can choose 15w-40 engine oil, because this oil has better fluidity and is more suitable for cold starts. Winter oil should be changed between October and November.

It is better to add antifreeze oil. In November or October, it will be replaced, and the weather at this time is not very good.

It is better to choose antifreeze engine oil when adding engine oil in winter, and the engine oil in winter is generally changed around October to November.

When buying engine oil in winter, you should choose one with high fluidity and anti-wear ability. Winter oil can be changed in November.

A lot of riders have heard of the concept of winter oil and summer oil, but few know the difference between them. Let's start with popular science:

Winter engine oil, generally 0w, 5w, 10w, etc. , w represents winter, the smaller the previous number, the lower the applicable temperature;

Summer oil, general, etc. , the higher the value, the higher the applicable temperature;

Generally, the 5w W-30 and other oil we use belong to the general purpose oil of winter and summer, and the riders who generally use this oil generally do not need to be replaced.

The previous figure w also determines whether it is the so-called winter oil or summer oil, generally more than 10w of oil belongs to summer oil.

If you use the car in the Northeast region, 10W is unacceptable, and it must be replaced with 0W or 5W, otherwise the viscosity of the oil is too high, it will not protect the engine, and it will even freeze.

Only 0w or 5w is common in 4s stores. This kind of engine oil is used in both winter and summer, and it belongs to the four seasons engine oil. So the maintenance in winter and summer is the same, so you don't have to worry about when to change the winter oil and when to change the summer oil.

However, if you buy your own oil, you should pay attention, especially for car owners in northern China, the oil consumption in winter cannot exceed 10w. If they have already been used, they should be replaced before winter.

Some motorists may be worried that even if they use the winter and summer engines, they will not be able to adapt to the local temperatures. In fact, this situation is redundant. Generally, during testing, the automobile manufacturer will mark the recommended oil label on the car manual according to the area where the car is used.

Generally according to this label, there will be no problem. Friends who regularly maintain their cars at 4S stores don't have to worry. The maintenance standards of the 4S store will strictly follow the maintenance manual, unless:

You go to a black shop.

Although there is no need to change the winter oil separately, it is still important to maintain the car on time during the winter.

Millions of car purchase subsidies.

The engine oils suitable for winter use are 0w, 5w, 10w, 15w, 20w, and 25w. The symbol W stands for winter. The smaller the value before w, the smaller the low temperature viscosity, the better the low temperature fluidity, and the lower the applicable minimum temperature.

In winter, the smaller the number in front of the use, the better the low-temperature fluidity of the oil, the lower the usable ambient temperature, and the better the protection of the engine during cold start.

Engine oil is the lubricating oil used in the engine, which has the functions of lubrication, anti-chaos and less wear, auxiliary cooling, sealing and leakage-proof, anti-rust and anti-corrosion, shock absorption and buffering.

0W engine oil is resistant to external low temperature -35 °C, 5W is resistant to external low temperature -30 °C, 10W is resistant to external low temperature -25 °C, 15W is resistant to external low temperature -20 °C, 20W is resistant to external low temperature -15 °C, winter and summer general engine oil is 5w W-30, Juexu 5w w w -20

The grades of summer oil are respectively. The higher the value, the higher the viscosity and the higher the applicable maximum temperature.

Car oil is the lubricant of the start, the oil should be changed regularly, so the owner friends ask, it is better to change the engine oil in winter or summer, it is recommended to change the car oil in the spring and autumn season. Because the temperature will cause the car oil to expand and contract, the high temperature oil will expand in summer, the temperature is low in winter, the oil shrinks, and the oil is added to the car when the oil is hot and expands and contracts.

Although it is not recommended to change the engine oil in summer and winter, it is also possible to change the engine oil in summer or winter, no matter what season it is, you must choose the right viscosity of the engine oil to change the car oil. According to different temperatures, there are winter engine oil, summer engine oil, and four-season engine oil on the market, mainly according to the viscosity value of the engine oil, and different oil viscosity is suitable for different temperatures.

Under normal circumstances, the applicable temperature of engine oil in winter is minus 50 degrees Celsius to 25 degrees Celsius, and the applicable temperature of oil in summer is minus 15 degrees Celsius to 55 degrees Celsius. Car owners can choose according to the actual situation.
