Can you use 10w 40 engine oil in winter?

Yes, but it is necessary to distinguish between the minimum temperature in winter in the area where the vehicle is used, which should be measured by the indicator of 10w-40 engine oil.

How to read 10w-40

First of all, 10 represents the index of low temperature start-up, the smaller the value, the better the performance of low temperature start-up, and 10 means that it can also ensure normal start at -25°.

W stands for the letter winter, which proves that this oil is suitable for winter.

40 represents the viscosity of the oil, the higher the value, the greater the viscosity of the oil, and the better the high-temperature sports type also has the high temperature shear viscosity.

Therefore, it is necessary to decide whether to use this type of oil according to the minimum temperature in the area where the vehicle is located.

It's better not to use it, it's too thick.

The oil label (the number on the oil drum) is selected as SF or above

10W---40, or 15--40 in summer, 10W--30 or 5W--30 engine oil in winter, such as 10W---40 can also be used in Zhengzhou, Henan Province, which can be used in winter and summer, and it should also be noted that SF or above should be selected, North China, East China, South China, it is recommended to use normal 5W-30 40 or 10W-30 40 engine oil, 10W-40 means that it is used between ambient temperature - 25 and +40.

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.

It works. 15w40 engine oil is a four-season engine oil, which is a composite engine oil, and such an engine oil can basically be used all year round. W is the abbreviation of winter, which means winter, 15 means that such engine oil can flow normally at minus 20 degrees Celsius, and 40 represents such a high temperature viscosity The larger the following number, the viscosity of the engine oil is also greater.

Engine oil is called the blood of the engine, and if there is no engine oil in the engine, the engine will not function properly.

Engine oil not only plays a role in lubrication in the engine, but also plays a role in cleaning, sealing, buffering, rust prevention and heat dissipation. When the engine is working, the engine oil will form an oil film on the surface of each component in the engine, which can prevent friction caused by direct contact between the various parts in the engine.

If the surface of the various parts in the engine is in direct contact and causes friction, it will affect the engine and cause huge heat instantaneously, which is fatal to the engine. Engine oil will basically reduce its performance after a long period of use, and it is natural that engine oil needs to be changed regularly. It is recommended that friends change the engine oil regularly when using the car.

And every time you change the engine oil, you basically have to replace the engine oil filter element together. If there is no engine oil filter, the engine oil will be very dirty after a period of use, which will affect the lubrication of the engine and aggravate the wear of the engine.

Fit. 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.

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.

OK. The minimum working temperature that 0W oil can withstand is minus 35 degrees, and the GT Magic Red 0W40 oil I use in Northeast China is no problem to use in winter, and it starts quickly in the morning. 0W is the best compared to 5W and 10W low temperature cold start protection.

Engine oil 0w-40 (not 0-40w) The front 0w represents the fluidity at low temperature The lower the number, the better the fluidity at low temperature The 40 at the back represents the viscosity of the oil at 100 The higher the number, the higher the temperature, the better the viscosity 0w-40 can basically be suitable for all regions of our country at present. Of course it can be used in winter. And your label is currently a high-grade motor oil.

Yes, it is more expensive than 5w in the same level, and a high level of 5w is recommended. The specific situation should also be prescribed in the vehicle maintenance manual.

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.
