Is 5w40 engine oil winter engine oil

5w40 engine oil belongs to winter engine oil.

The oil designation usually indicates viscosity and quality. The viscosity of lubricating oil is mostly marked by SAE and other grades, and SAE is the abbreviation of the English "Society of Automotive Engineers". w stands for winter (winter), the more ** the number in front of it, the better the low temperature fluidity of the engine oil, the lower the ambient temperature available for use, and the better the protection ability of the engine during cold start; The number after the "W" (after a horizontal line) is an indicator of the high temperature resistance of the engine oil, and the higher the value, the better the protection performance of the engine oil at high temperatures.

The label after the classification of the engine oil indicates its viscosity specifications, for example, in "15w w-40", "w" means winter (winter), the more ** the number in front of it, the better the low temperature fluidity of the engine oil, the lower the ambient temperature available for use, and the better the protection ability of the engine during cold start, such as 5w represents the external low temperature resistance -30 °C, and the 20w low temperature resistance is -15 °, and the number behind the 20w low temperature resistance is -15 ° represents the kinematic viscosity of the oil at 100, the higher the value, the higher the viscosity. 40 represents 100 degrees Celsius, and the kinematic viscosity standard is between to.

It's not winter engine oil, it's 30's.

Now it's better to use 10w-30 stabilization.

5w40。

The difference between 5w-40 and 5w-30 is only the difference between the following numbers, 40 can be used in summer temperatures below 40 degrees, and 30 can be used in temperatures below 30 degrees.

The winter oil grades are: 0w, 5w, 10w, 15w, 20w, 25w, the symbol w represents winter, the smaller the number before w, the smaller the low temperature viscosity, the better the low temperature fluidity, the lower the applicable minimum temperature, the summer oil grade is , the larger the number, the greater its viscosity, the higher the applicable maximum temperature.

Oil precautions.

In the winter, when the temperature is low, the oil will become viscous and become semi-solid and semi-fluid, which will not flow smoothly, and the oil of poor quality will even stop flowing completely, and it will take longer for the oil to flow to the inside of the engine.

Therefore, if you start immediately after starting in the morning to work, it will cause dry wear, and over time it will strain the inside of the cylinder, resulting in engine wear, and in severe cases, it will be accompanied by abnormal noise.

It is good to use 40 in winter, and the anti-freezing ability is strong.

It's still 5w40 good, the bigger the oil number in winter, the more it carries the freezing, especially in the cold northeast, choosing this 5w40 is the best.

It depends on what kind of car you use, 30 and 40 are mainly the difference in viscosity. Choose the one that's right for you.

5w40 and 5w30 comparison, in the cold start performance is the same, but the viscosity of the oil is higher, the higher the viscosity of the oil, the better the sealing, the engine will be more fuel-consuming, in the idle state, the oil viscosity is high, the noise is lower, in the driving state, the oil with high viscosity, the noise is higher. The low viscosity has the characteristics of fuel saving.

The 5W in the 5W-30 indicates the performance of the oil cold start. Using an oil with a lower value in front of the engine makes it easier to start the engine in cold weather. 5 out of 30w-30.

Indicates the viscosity characteristics of motor oil at high temperatures. A high-viscosity motor oil (with higher values) may be better suited for vehicles traveling at high speeds or heavy loads.

Summary. Dear, I'm glad to answer for you, it's better to use 5w30 or 5w40 oil in winter, 5w30 is better. The high temperature kinematic viscosity of 5w40 oil is higher than that of 5w30 oil, and in winter it can be lower viscosity oil, and the lower viscosity oil flows better.

If the temperature in the area is low in winter, it is recommended to use 0w oil, which can flow normally at minus 35 degrees Celsius.

Engine oil, that is, engine lubricating oil, can play a role in lubrication and wear reduction, auxiliary cooling and cooling, sealing and leakage, rust and corrosion prevention, shock absorption and buffering for the engine. It consists of two parts: base oil and additives. Base oil is the main component of lubricating oil, which determines the basic quality of lubricating oil, and additives can make up for and improve the deficiency of base oil energy and give some new energy.

Plain as day. The lower the viscosity of the oil, the thinner the oil film and the better the fluidity, but the lower the protection under high temperature and pressure. On the contrary, the viscosity is high, the oil film is thicker, the fluidity is weakened, and the high temperature protection is good.

As the saying goes, the more viscous engine oil is, as the saying goes, thicker, more difficult to stir, and naturally consumes more energy, just like walking in water, which is always more strenuous than walking on flat ground.

I used 5w40 engine oil before the Northeast, which was useless, and it was still very difficult to get up in winter, and there was no power just to listen to the movement. The 0W40 German GT Magic Red that I am now changing to is much easier to use, and the quality of this PAO base oil is also good, and there is no problem when I start the car in winter, which is the same as usual, and the difference is much more obvious.

5W-30: W is the meaning of winter, the previous number represents low temperature fluidity, the smaller the number, the better the low temperature fluidity (0w engine oil is recommended for cold areas); 30 is the high temperature index (viscosity), the greater the math, the higher the viscosity (thicker), the better the sealing, but the mechanical loss of the engine will increase (fuel economy will decrease), the smaller the math, the smaller the viscosity (thinner,) the better the fuel economy, but the poor sealing. The winter in the Northeast is cold, it is recommended to use 0w engine oil (good fluidity at low temperature), 30 or 40, depending on the specific situation of the car (40 for old cars, 30 for new cars).

0w20 and 5w30 are two completely different types of engine oil, 0w20 is mainly used in Japan, the United States, South Korea and other automobile engine clearance is larger. 5W30 is mainly used for German and other automobile engines with more fine engines. In short, following the manufacturer's guidance is the most scientific.

1. Normal driving in a normal use environment, such as Japanese cars 0w20 is enough. However, if you are driving aggressively, or if you are in a place with a high climate temperature, then it is enough to change to 0w30 or even 0w40, because Japanese cars must ensure that the oil has enough fluidity.

2. The engine of the current German and European cars is more fine, and it can be fully used in winter and summer general engine oil, and the common 5w30 can basically meet the needs, and 5w40 has basically no problem in the Chinese environment.

3. Finally, remember to follow the manufacturer's guidance.

Aconi lubricants answer for you, the difference is not big, often drive at high speed with 40, commute with 30.

Hello, dear <>

The difference between these two types of engine oil is that the number in front of W represents low-temperature fluidity. It is the fluidity of the engine oil at low temperatures, and the smaller the number in front of this w, the better the fluidity of the oil at low temperatures. That is to say, the fluidity of this 4w-40 oil is better than that of 5w-40 oil at low temperatures.

Aconi lubricants are the answer for you, 5w40 is the all-season oil.

In winter, it is generally better to use 5w30 oil.

5w30 and 5w40 these two oils, through the number can know that the use of these two oils in low temperature conditions is the same, the difference is the part behind the "w", the larger the number of this part, the greater the viscosity of this oil, in winter it is best to use a less viscous oil, so you can choose the "30" type of oil.

In general, in winter, the car mainly selects suitable for low temperature conditions and the viscosity of the oil is relatively small, the choice of this type of oil has great benefits, so that the engine can reduce the resistance when running, so as to achieve the purpose of fuel saving, but also a good protection engine is not easy to be worn.

Oil:

Engine oil, that is, engine lubricant, English name: engine oil. The density is about to lubricate and reduce friction, assist cooling and cooling, seal leakage, rust and corrosion, shock absorption and cushioning for the engine. Known as a car"Blood"。

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.
