Is it better to change the engine oil in all seasons or use seasonal oil

Normally, multi-grade viscosity oil, in addition to the change in the selection of low-temperature viscosity in winter, the high-temperature viscosity does not change with the use of summer, because the temperature of the engine after fully heating up is about the same in winter and summer, all around 90-100, then if the original factory of your car recommends that the viscosity of the engine oil is 5w-30 in winter, you can also use this viscosity oil in summer. Hope.

Kiss! If it helps you, thank you ( If you have any questions, you can ask them!)

Many people find that after changing the engine oil under low temperature conditions, sometimes the engine performance is significantly reduced, and even there are difficulties in starting, insufficient power, weak acceleration, and increased noise, which is actually the reason for the wrong oil.

As we all know, engine oil can be said to be the "blood" of the engine, with multiple functions such as lubrication, sealing cylinders, cooling and cooling, and cleaning. Among them, the lubrication characteristic is to rely on the adhesion of the engine oil to form an oil film on the surface of the part, thereby reducing the wear and tear inside the engine. Although engine oil is particularly mysterious in the eyes of many whites, in fact, as a kind of oil, it is also affected by temperature changes like edible oil and kerosene.

In low-temperature areas, the use of conventional engine oil may not be able to cope with the changes caused by the lower temperature, which may affect the performance of the engine. In order to give full play to the engine performance, it is best to use special engine oil in low temperature environment.

When the temperature is low, what kind of oil does your car need to be replaced?

So what kind of engine oil is suitable for low temperature environments?

If we want to know what kind of engine oil should be used in a low temperature environment, we should first distinguish what types of engine oil there are. Generally speaking, the engine oil itself is divided into many different types such as 5W W-40, and this provides us with a clear classification. In the designation, the "w" stands for winter, while the "0" and "5" indicate that it is limited to an ambient temperature of -35°C or -30°C.

The higher the number in front of w, the worse the low temperature fluidity, and the smaller the number, the better the low temperature fluidity. As for the 30 and 40 marked after "—", they represent the relative kinematic viscosity of the engine oil at 100°C, and the larger this number, the higher the high-temperature kinematic viscosity and higher the high-temperature adaptability.

The adhesion of motor oil is generally determined by its own kinematic viscosity, which is affected by the temperature of the oil. When the temperature rises, the kinematic viscosity of the oil will decrease, resulting in a decrease in its adhesion and failure to achieve the desired lubrication effect. Conversely, when the temperature drops, the kinematic viscosity of the oil increases, resulting in an increase in oil adhesion, which increases the load on the engine and thus increases fuel consumption.

Some common motor oils often perform well in high temperature viscosity, but perform poorly in low temperature fluidity, which makes ordinary motor oil not suitable for low temperature environments. To really fit the engine oil in the low-temperature environment, you should choose the type with good low-temperature fluidity. That is to say, the oil that we often reduce starts with 0w and 5w, and the limit environment can reach as low as -35°, which is enough to cope with low temperature conditions in various places, so that the engine is not afraid of low temperature environment.

Choose a good model, but also choose a good brand.

Due to the harsh environment test brought by low temperature, there are not only high requirements for the low-temperature fluidity of engine oil, but also more requirements for the brand of engine oil. So what kind of engine oil brand should we choose in a low temperature environment?

Four seasons oil can also be used in winter. All-season engine oil refers to the all-season engine oil, for example, SAE 5W-40 in SAE viscosity grade is all-season engine oil, which belongs to long-lasting engine oil. 5 represents the flow capacity of the low-temperature engine oil in winter, the smaller the number, the better the fluidity at low temperatures, and 40 represents the ability of the oil to withstand the load at high temperatures.

Winter or summer engine oil, mainly on the outside of the oil barrel has a mark, according to the symbol can be judged what temperature the oil is suitable for. For example, 5w-40, then this oil is all seasons. It can be used from minus 20 degrees to minus 40 degrees.

All seasons engine oil can be applied in most parts of the country, except for the extremely cold Northeast region. The smaller the number in front of the four-season oil, the stronger its low-temperature fluidity, which means that it can adapt to the colder the region.

At present, the engine oil is mainly divided into mineral oil, semi-synthetic engine oil and fully synthetic engine oil, in terms of performance, the fully synthetic engine oil will be much better than the other two, and the service life of the fully synthetic engine oil will be relatively long.

It is recommended to change the mineral oil at 4000-5000 km, the semi-synthetic oil is recommended to be changed at 5000-7500 km, and the fully synthetic oil is recommended to be changed at 7500-10000 km. At the same time, if we often drive in bad road conditions, the oil change interval should be appropriately advanced.

Hulunbuir you said has a low temperature of minus 40 degrees, and it is best to use winter antifreeze oil directly in winter, and use antifreeze oil at minus 40 degrees. This will save a lot of trouble, some people do not change the antifreeze oil in time in winter, and the car will not start in the case of ultra-low temperature.

Is it better to use all-season engine oil in winter or winter engine oil? This problem, first need to understand that you are driving in **, if the weather is about minus 10 degrees in the north, you must use special antifreeze oil in winter, and the water tank should also use (high-level) antifreeze. If it is the south, you can just use four-season engine oil.

There's no need to spend more money on that special antifreeze oil.

It is best to use the SAE 0W model oil with a minimum temperature of minus 35 degrees Celsius.

The models of Four Seasons engine oil include 5W W-305W-40, 5W-50, 10W W 0W W-2015W W W-50 and so on. 5w is better.

This is also a way to adapt to different use environments across the country. In addition, the number after W represents the viscosity of the oil at 100, the higher the value, the higher the viscosity at high temperatures, and the wider the applicable temperature range. This value can also be seen as an indicator of the performance of the oil in the summer.

Key Benefits: These oil models:

A general-purpose motor oil that can withstand both high temperatures in summer and low temperatures in winter. In the model of engine oil, W stands for winter, that is, the abbreviation of winter, the smaller the number in front of W, the smaller the low temperature viscosity of the engine oil, the better the low temperature fluidity of the engine oil, and the lower the minimum temperature for application.

Let's use the engine oil model number as 5W 30 as an example, first of all, the engine oil model contains the letter "W", which means winter. The "5" indicates that the oil has reliable low temperature start-up at minus 30 degrees, the lower the number, the stronger the cold resistance of the oil, and 30 represents the kinematic viscosity standard at 100 degrees Celsius (to).

Normal 0W and 5W labels are all four-season general engine oil, choose the viscosity label suitable for your own car, like I am a German car, before using 5W40 original factory fully synthetic, the cold start experience is generally replaced by 0W40 GT Magic Red engine oil, the base oil of the four types of PAO has good low-temperature fluidity, long-term durability, and the addition of esters, the power is sufficient, and the experience is much better than those used before.

I've been using German Magic Red engine oil, although this oil is not very famous, but its performance is better than the big brands of engine oils I used before, because his PAO base oil content is relatively high, and he used to do additive research and development!

Mineral oil; semi-synthetic motor oil; Fully synthetic motor oil; Regardless of the car environment and driving habits, the oil change interval of mineral oil is 5000 kilometers or half a year; The oil change interval for semi-synthetic motor oil is 7500 km or seven months; The oil change interval for fully synthetic oil is 10,000 km or one year; It is recommended to use fully synthetic engine oil, with long-term engine filter, which can better protect the engine and save costs.

1.Engine oil, that is, engine lubricating oil, can lubricate and reduce friction, assist cooling and cooling, seal leakage, rust and corrosion, shock absorption and cushioning for the engine. It is known as the "blood" of automobiles.

2.Engine oil is made up of two parts: base oil and additives. Base oil is the main component of lubricating oil, which determines the basic properties of lubricating oil, and additives can make up for and improve the shortcomings of base oil performance, give some new properties, and are an important part of lubricating oil.

3.The 5W W-30 and so on in the engine oil indicate the viscosity grade of the engine oil, which is the SAE grade. "W" means winter.

The smaller the number in front of w, the smaller its low temperature viscosity, the better the low temperature fluidity, and the lower the applicable minimum temperature. The number after w does refer to the viscosity of the oil at 100 degrees Celsius, and the higher the number, the more viscous the oil. The following figures mainly refer to the index of the high temperature resistance of the oil, and the better the protection performance at high temperatures.

4.Fully synthetic engine oil: Fully synthetic engine oil has better high and low temperature performance, longer oil change interval and is suitable for more severe car conditions, suitable for luxury high-performance vehicles, and is replaced at about 10,000-12,000 kilometers.

5.Semi-synthetic engine oil: The replacement cycle of semi-synthetic engine oil is generally about 8000-10000 kilometers, and the performance is moderate.

6.Mineral oil: This type of oil generally needs to be replaced after about 5000 kilometers.

Try to choose multi-grade oil, multi-grade oil has a better protection effect on the engine due to saving, long life and high efficiency. Based on the characteristics of multi-grade oil, premature blackening and oil pressure may be smaller than that of ordinary oil during use, which is normal.

Summary. This oil can be changed at any time, this has nothing to do with the weather, that is to say, even in winter, this can be changed oil, that is, in the process of changing the oil, that is, as long as the engine runs for more than half an hour, the temperature of the engine will reach a normal range, so the viscosity of his oil is compared. The viscosity of the engine oil is relatively low, and the viscosity of the engine oil is relatively thin, so if you change the engine oil, he will release it relatively cleanly, and this has nothing to do with the climate, and it can be replaced at any time.

Of the four seasons of the year, it is better to change the engine oil.

Hello, I have seen your inquiry, please wait for a moment and answer it for you immediately.

Hello, happy to answer your questions.

Of the four seasons of the year, it is better to change the engine oil.

This can be changed at any time to change the oil, this has nothing to do with the weather, that is, even in winter, this can be changed oil, that is, in the process of changing the oil, that is, as long as the engine runs for more than half an hour, the temperature of the engine will reach a normal range, so the viscosity of his oil is more sideways. The viscosity of the engine oil is relatively low, and the viscosity of the engine oil is relatively thin, so if you change the engine oil, he will release it relatively cleanly, and this has nothing to do with the climate, and it can be replaced at any time.

See.

The difference between winter engine oil and four-season engine oil is: different ambient temperature, different kinematic viscosity, and different protection ability.

First, the ambient temperature is different.

1. Winter engine oil: The ambient temperature of winter engine oil is lower.

2. All-season engine oil: The ambient temperature of all-season engine oil is higher.

Second, the kinematic viscosity is different.

1. Winter engine oil: Winter engine oil has higher kinematic viscosity and better fluidity at low temperature.

2. All-season engine oil: The four-season engine oil has lower kinematic viscosity and better fluidity at high temperature.

Third, the ability to protect is different.

1. Winter engine oil: Winter engine oil has a better ability to protect the engine during cold start.

2. All-season engine oil: All-season engine oil has better protection ability for the engine during hot start.

Fourth, the oil type is different.

1. The grades of winter oil are: 0W, DU5W, 10W, 15W, 20W, 25W, the symbol W represents winter, the smaller the number before W, the smaller its low temperature viscosity, the better the low temperature fluidity, and the lower the applicable minimum temperature;

2. The four seasons of oil grades are respectively, the larger the number, the greater its viscosity, and the higher the applicable maximum temperature;

It is an all-season motor oil. Now I basically use all season engine oil 5w-30 10w-40 15w-40!! SAE divides motor oils into two categories according to their viscosity grades, which are single-grade viscosity and multi-grade viscosity.

The single-stage viscosity type is divided into a type for high temperature environment and a type for low temperature environment. The special engine oil for high temperature environment is marked with SAE30, SAE40, SAE50, etc.

Four seasons engine oil can be used regardless of spring, summer, autumn and winter, and winter engine oil can only be used in winter, which has limitations.

The condensation point is different, and the condensation point of engine oil is low in winter.

Hello, now most of the engine oil is four-season engine oil, divided into mineral oil, semi-synthetic, fully synthetic, fully synthetic oil is the best, mineral oil is the worst, such as the oil model is 5w-30, the smaller the number in front of w, the better, the larger the number in the back, the better, choose the right oil according to the ** of your own vehicle, thank you.
