Which is better to use 0w40 engine oil or 5w30 engine oil in winter?

The lower the number before 0W40W, it means that the low temperature fluidity is good and the starting performance is good, and the oil viscosity is behind the W, the greater the high temperature fluidity.

0w-40 has a wider range than 5w-30 and is better.

5w-30, 0w-30, 5w-40, 0w-40 refers to the viscosity of the oil.

5W, 0W refers to the low temperature viscosity characteristics of the oil.

0W flows better at low temperatures than 5W. Of course, ** is also more expensive.

If you live in an area where the temperature does not fall below -15°C, 5W is fine. Similarly, the latter 30, 40 refers to the viscosity characteristics of high temperatures when the engine is operating normally.

The viscosity of the oil required by different engines is different.

Hello, the lower the number before W, it means good fluidity at low temperature and good starting performance, and behind W is the viscosity of the oil, the greater the fluidity at high temperature. 0w-40 has a wider range than 5w-30 and is better. Hope it helps.

The difference between 0w40 and 5w40 is: different references, different definitions, and different emphasis

Refers to different ones. W40: Refers to fully synthetic motor oil.

W40: Refers to semi-synthetic motor oil.

Main advantages: 0w40: synthetic engine oil is a kind of artificially manufactured engine oil, in the production process, a variety of natural substances are selected for chemical decomposition, and then synthesized with various other substances, and finally the synthetic engine oil is produced. Synthetic engine oil manufacturers produce various types of synthetic engine oil according to user requirements.

In other words, synthetic motor oil can change its composition depending on the purpose for which it is used.

5W40: Semi-synthetic oil (semi-synthetic lubricant) is one of the automobile engine oil, semi-synthetic oil is the use of semi-synthetic base oil, that is: the international three types of base oil to prepare lubricating oil, is based on the mineral oil after hydrofission technology purification products, it is made of mineral oil, fully synthetic oil to 4:

6 The purity of semi-synthetic oil is very close to that of fully synthetic oil, but its cost is slightly higher than that of mineral oil; It is an ideal transition product from mineral oil to synthetic oil.

Of course it's 0w, if you're in the south, 5w is enough, 5w-40 and 0w-40 have the same viscosity performance when the vehicle is working normally, there is no difference. The biggest difference between the two is the working capacity of the low temperature environment, 5W oil can ensure the normal start of the vehicle in the environment of minus 30 degrees, while 0W oil can be used normally at minus 35 degrees. Don't underestimate this little 5 degrees, the production requirements for engine oil are much higher, so 5w engine oil will have different grade classifications, and 0w engine oil base oil grade can only use the best, ** is naturally expensive, of course, if we want to use good engine oil but don't know how to distinguish the grade from bad, then 0w is the best.

I use 0w40 engine oil all year round, the temperature here in winter is not very low, 0w40 engine oil I use not only feel more resistant to low temperature than 5w40, other aspects are also significantly improved, of course, it also depends on what brand of engine oil is used, I have been using GT magic red, PAO's fully synthetic engine oil performance is indeed much better than most of the three types of fully synthetic engine oil.

The quality of 0w engine oil is much better than that of 5w engine oil, and there are many traffic jams on my side, and the car also has to stop and go. I usually take care of the car, and the 5w40 I used before didn't feel very good, so I used GT Magic Red engine oil 0w40, the oil has liquid molybdenum in it, the wear resistance is particularly good, it can effectively protect the engine, and it is a four-class PAO base oil, the oil is long-lasting and durable, and there is no problem with changing it for a 15,000 kilometers, and it is much longer than the previous maintenance.

My Magotan originally used the original 5w40 engine oil also has a lot of abnormal noise, and there is obviously no big problem with the GT Magic Red 0w40 engine oil, the sound is small, and the power is enough for a long time.

0w40。For the oil 5w40 and 0w40, the high temperature viscosity performance of the two is the same, the difference lies in the low temperature fluidity of the oil, the low temperature fluidity of the 0w40 grade oil is better, and the temperature can be lower to minus 35, while 5w40 is slightly worse, the minimum can only withstand the temperature of minus 30. The lower value of the oil in front of the engine makes it easier to start the engine in cold weather.

Precautions for the use of engine oil.

In summer, the temperature of the vehicle's surroundings is inherently high, combined with the heat generated by the car's engine, which makes the temperature even hotter. At this time, once the oil is used carelessly, it will be easy to have undesirable situations such as low oil pressure and bright lights.

The engine is a very critical part, and special attention should be paid to its cooling system. When the ambient temperature rises, the temperature of the engine will rise, so that the engine can maintain high temperature operation for a long time, it is easy to oxidize the oil and produce deterioration, so that the viscosity declines and loses the lubrication effect.

There is no one who is good and who is not, depending on the temperature of your location, generally speaking, 5w40 engine oil is completely fine, and the difference between them is the condensation point of the lowest temperature. 5w40 is iced at minus 30 degrees, and 0w40 is iced at minus 35 degrees. Hope to adopt, thank you!

Hello, 5W-40 and 0W-40 are both labels for engine oil. The letter W stands for winter, and in fact the oils with the letter W are all winter and summer general purpose motor oils.

The number 40 represents the high temperature viscosity grade of the engine oil, the higher the number, the stronger the high temperature viscosity of the engine oil, the thicker the thickness of the oil film, and the better the sealing and protection ability.

The numbers 5 and 10 represent the minimum applicable temperature of the oil, or the low-temperature fluidity. 0 means that the minimum applicable temperature of the engine oil is minus 35 degrees, and 5 means that the minimum applicable temperature of the engine oil is minus 30 degrees.

0w40 is relatively good when the weather is cold, I hope it helps you, thank you!

Which one to choose should be based on a number of factors:

1. Look at the car system

First of all, we all know that American cars, the engine is more precise, the gap between parts is smaller, and the oil of 5w-30 is the most suitable. As for German cars, turbocharging technology is usually used, and the gap will be relatively large, and it will be relatively better to choose 5W-40.

Japanese and Korean cars will use more viscous oils, such as: SAE 0W W W W-30; The American system recommends using 30 viscosity, such as: SAE 5W-30, and the European system uses 40 viscosity, such as:

0w
w-40。

2. Look at the age of the car

Each car will be equipped with a maintenance manual as standard, referring to the maintenance manual on the car, new cars usually choose a slightly lower viscosity oil, then add 5w-30, Japanese and Korean cars can use 0w20. As the car ages, slowly choose a slightly more viscous engine oil, because the wear of the older car engine will be more serious, choose a relatively higher viscosity oil 5w-40.

3. Look at the road conditions

In addition to the above two points, road conditions are also a very critical point, for the impact of oil life, poor road conditions in the area, should be quite short oil change cycle, and in the urban area due to more vehicles, often frequent start and stop, it is recommended that the viscosity is lower, SN5W-30 will be very suitable, if it is often run long distances and the like, it is recommended to SN5W-40.

4. Look at the season

You should know that the season is different, and the choice of engine oil is also different Generally, within the reasonable range specified in the driving manual, the engine oil with better fluidity will be recommended in winter, that is, 5w30, and the oil with higher viscosity will be recommended in summer, that is, 5w40. However, in some areas, 5W-30 and 5W-40 engine oil can be used, so don't worry too much.

Hello, friend, your oil, this is different according to your model, the use is different, if your car compares this new car, I personally recommend using this 530 of 5w30. If the car is relatively old, it is recommended for personal use to recommend this 5w40. Because if the car is relatively long, use this 5w4o engine oil, which has an effect on burning the engine oil.

Question: Which is the best Odyssey? In 2017, 30,000 kilometers were driven.

Question: With 30, a little burn oil, 8000 kilometers is probably less liters, is it normal?

Question: Oh, the garage said that you can switch to 40 engine oil, is that okay?

Question: Okay, how many kilometers does a normal fully synthetic engine oil be changed?

Question: I went 8000 kilometers to change, and the oil was less, what is the reason?

If you answer that this engine oil is a loss, this is a friend with loss. If you are like this liter, this is basically within the normal range, and this waste-gas valve is a loss. This doesn't matter, you can use this five w40 to try it, basically it can be improved.

Hello question, thanks!

Good evening, this depends on what brand of vehicles to use, Japanese vehicles are recommended to use 5w30, German vehicles need to use 5w40, and the specific oil viscosity needs to be selected according to the outdoor temperature, the more ** the number in front of "w", the better the low temperature fluidity of the engine oil, which means that the lower the ambient temperature that can be used, the better the protection ability of the engine during cold start; w The number after the w is the index of the high temperature resistance of the engine oil, the higher the value, the better the protection performance of the engine oil at high temperatures.

5W for -30°C 10W for -25°C 15W for -20°C 20W for -15°C W The number 30 behind it represents high temperature resistance, 30°C 40 high temperature resistance, 40°C resistance 50 high temperature resistance 50°C

This indicator is not good or bad, this refers to the "viscosity" of the oil, 5w-30 oil is a little thinner than 5w-40 oil, 5w-40 is a little thicker than 5w-30. If the car is less than 5 years old, it is recommended to use 5w-30 engine oil, and if the car is more than 6 years old, it is recommended to use 5w-40 or 10w-40 engine oil.

5w30 is sufficient.

5w30, the minimum operating temperature is minus 30

The winter oil grades of SAE lubricating oil viscosity classification 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, and the lower the applicable minimum temperature;

The higher the number, the greater the viscosity, and the higher the applicable maximum temperature;

We all know that engine oil is very important for the engine, but many car owners have a lot of misunderstandings on the issue of changing the engine oil, and if you don't pay attention, it will not be good for the engine.

I found that 5w30 is more expensive than 5w40.,But it seems to say it's 5w40.,It's not clear.,Come up and ask the master.。。。 In addition, there is no problem with the Sega Plus 5w30 or 5w40.
