Can 10w forty engine oil be used in the north in winter

Can be used. At present, the engine oil on the market mostly uses SAE and other grades to identify the viscosity, where "W" means winter, the more ** the number in front of "W", the thinner the engine oil, the better the low-temperature fluidity, the better the cold start ability, and can be used in a lower temperature environment.

The temperature in the northern region is lower in winter, so it is recommended to use 0w, 5w or 10w oil. Most of them choose a viscosity of 5w-30 or 10w-40. Generally, the smaller the number in front of W, the better the fluidity of the oil, 5W can be applied to minus 30 degrees Celsius, and 10W can be used to protect the engine at minus 25 degrees Celsius.

In environments above minus 25 degrees Celsius, it is no problem.

The number after "w" (one horizontal back) 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.

10W-40 is the SAE (Society of Automotive Engineers) viscosity standard used to distinguish the different temperature ranges for which lubricants are suitable. "W" stands for winter, and the higher the number in front of it, the better the low-temperature fluidity of the oil, which means that the lower the ambient temperature available for use, and the better the protection ability of the engine during cold start; The number after "w" (one horizontal back) 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. 10w-40 engine oil can generally be used between minus 20 degrees and minus 40 degrees, that is, most parts of our country can use this brand of engine oil all year round.

Depending on what kind of car you use, the single-cylinder one uses a 5w one

With 10w40 oil, the high temperature performance is enhanced, which reduces the probability of burning the engine oil, but the performance of low temperature cold start and winter antifreeze performance will be reduced, and the engine may have problems in winter. The w in the viscosity index represents winter, the number before w indicates low temperature performance, the smaller the number indicates the better low temperature performance, the number after w indicates high temperature performance, and the larger the number indicates the better high temperature performance.

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.

It is known as the "blood" of automobiles. 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.

Motor oils are divided by viscosity.

10W-40 is its SAE standard viscosity value, this viscosity value first indicates that the oil is a multi-grade engine oil, W stands for winter, the number in front of W represents the flow performance at low temperature, the smaller the value, the better the starting performance at low temperature. The number after w represents the stability of the oil at high temperatures, and the higher the value, the better the stability of the oil at high temperatures.

This depends on the temperature of your living environment and the quality of your oil.

Under normal circumstances, 10w-40 engine oil can adapt to the temperature of minus 25 degrees or minus 40 degrees.

It can be used if it is difficult to ignite the car department in winter.

It can be used in places where the temperature is not particularly low.

For 15w40 engine oil can be used in winter depends on the local temperature conditions in winter and summer, it can be used in winter in the southern region, and it is not suitable for low temperature in northern areas such as Harbin.

The 15w40 engine oil is used in most areas for all seasons, and the applicable temperature range is -20 100. 40 represents the kinematic viscosity standard at 100 degrees Celsius.

15W-40 lubricating oil suitable temperature range -20 +40, in North China and the central and western regions of winter and summer.

If you are in the Northeast, you can still use it this month, and you should change to 5w-30 or 5w-40 next month.

15w--40 ambient temperature -20--40, where the temperature is lower, please choose 0 or 10w-40 oil. It's best not to use 15w-40

Hello! It can be used in the south, and the oil in the north needs to be changed with viscosity.

It can be used, but the viscosity is too large, and the resistance to low temperatures is relatively poor.

Hello, you can do it in the south of Jiangsu, but you can't in the northeast.

Hello, the viscosity is a bit large, it is recommended to use it in winter or 5w30 engine oil!

OK. 10w-40 engine oil, generally above minus 20 degrees can be used normally, the temperature in the northern Harbin area can be as low as minus 20 degrees to about 30 degrees, 10w-40 oil is not suitable, should use 5w-40 or 0w-40 oil.

10W-40 is the standard viscosity value of SAE, and W stands for Winter. The grades of winter oil are: 0w, zhuan5w, 10w, 15w, 20w, 25w, the smaller the number before w, the smaller the low temperature viscosity, the better the low temperature fluidity, and the lower the applicable minimum temperature.

The number after the w represents the oil at 100.

10W-40 engine oil is a four-season engine oil that can be used in the winter in the northeast and southeast.

The minimum temperature that 10W-40 four-season engine oil can withstand is minus 35 degrees, but the four-season engine oil is also divided into many kinds, and the cold resistance of a four-season engine oil can be judged by the number a long time before W, the smaller the number before W, the stronger the low temperature fluidity, and the more adaptable it is to the colder the area.

The oil with the number 0 is the most hardy and can be used in weather temperatures as low as -35 degrees. An oil starting with 5 can be used above -25 degrees, 10 can be used above -20 degrees, and 20 can be used above -10 degrees.

It is a four-season engine oil, with w for winter and 40 for spring, autumn and summer. The minimum applicable temperature of the oil is minus 25 degrees, which should be no problem in the northeast and southeast, especially when the car is not running day and night.

10w-40, "w" stands for "winter" which means used in winter, and the "10" in front of "w" represents the viscosity at low temperatures. "40" refers to the viscosity at 100, and the higher the number, the higher the viscosity and the stronger the ability to withstand high temperatures.

SAE is the English abbreviation of the Society of Automotive Engineers of America, and the SAE grade represents the viscosity grade of the oil. SAE30 and SAE40 are single-grade oils, and SAE10W 30 and SAE15W 40 are multi-grade oils. Among them,"w"The higher the previous number, the lower the viscosity at low temperatures, the better the protection ability of the engine during cold start; "w"The following figures are an indicator of the oil's resistance to high temperatures.

The frost resistance of this oil is a bit low, because for use in the Northeast, it is recommended to use a higher frost resistant type of oil.

Hello, it is not universal in all seasons, the general reason for the four seasons is 0w-30, and it will be difficult to start the car in cold places in winter. [Car questions, ask the car master.] 4S shop professional technician, 10 minutes to solve. 】

Hello, 10w-40! It is very suitable for high temperatures, low temperature fluidity is not good, and the starting car is not good. This is still not recommended in winter. Hope to help you [car questions, ask the car master. 4S shop professional technician, 10 minutes to solve. 】

Fit. 10w40 oil is generally suitable for minus 25 degrees or minus 40 degrees, the owner can make a reasonable choice of engine oil according to the local temperature, the use of winter car oil will be marked on the maintenance manual of the car, and the owner who does not grasp the oil label can refer to the maintenance manual or consult the relevant maintenance personnel.

Oil 10w40 refers to the viscosity of the oil is 10w40, the number in front of w represents the cold start performance, the smaller the number, the easier it is to start the engine in cold weather, the common ones are 0w, 5w, 10w, 15w. And 40 of them indicates the viscosity characteristics of the 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.

10w40 oil in the environment above minus 25 degrees is no problem, to be honest in the northeast has also stayed, the winter is too cold, I think it is better to change to a more low-temperature resistant 0w oil, I was a winter self-driving tour to you to see the ice sculpture, deliberately changed their oil to Germany imported 0w30 GT oil, it is very resistant to low temperature, minus 45 degrees is no problem, and in your hot car start time is relatively short.

I am Changchun City, Jilin Province, when I changed the oil, the car repair factory gave me a change of 10w-40 engine oil, I asked him if this can survive the winter, he said yes, I asked again, and also said that it can survive the winter, between -30-25 degrees, I really came over, a fire.

10w40 is to say that the low temperature fluidity of the oil is minus 25 degrees, is 40 viscosity marking, the quality of the engine oil is not very good, now I do not use much, I have been using g t magic red 0w40 label oil, the oil quality is very good, there is the addition of liquid molybdenum, the anti-wear protection ability is very good, the respect effect is obvious, the engine is very quiet and easy to maintain.

In summer, you can use a more viscous engine oil, and in winter, it is more suitable to use a thinner engine oil, so the 10w-40 model engine oil is more suitable for use in summer.

For a motor oil, 10W-40 is its SAE standard viscosity value, this viscosity value first indicates that this oil is a double lubricating oil (now there is basically no slip in the civil field, there is no single-stage positive base no lubricating oil), W stands for 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. 40 represents the kinematic viscosity at 100 degrees Celsius, and the higher the number, the higher the viscosity of the oil.

The various models are not used to distinguish performance, but to represent the use environment, the minimum operating temperature is -25 degrees, and the oil can still maintain the viscosity of No. 40 oil at 100 degrees Celsius.

1. High temperature stability is different.

The number after w indicates the kinematic viscosity of the engine oil at 100, and the larger the number, the greater the viscosity, which means that the guarantee is better and more stable at high temperatures, that is, it is less likely to thin at high temperatures. That is, 5w40 is more stable at high temperatures than 5w30.

2. The objects of use are different.

5w40 has a better viscosity than 5w30, so it is more suitable for old cars, 5w30 is more effective in reducing fuel consumption, making the engine faster and better heat dissipation, and at the same time less noise, suitable for new cars or naturally aspirated engines.

The difference between the two labels of 5w30 and 5w40 is that the viscosity index is different at 100 degrees, and the viscosity of 40 is greater than 30, which is suitable for use in the north not less than minus 35 degrees, and the turbocharged engine is recommended to use 40.

What are the differences between engine oil 5w30 and 5w40? Which grade of motor oil is more suitable for northern winters? Because of the cold weather in the north, it is still more suitable for 5w30 grade oil.
