What is the difference between engine oil 10w40 and 5w40, and which one is used to improve power?

The difference lies in the level of fluidity at low temperatures. The power is not good, mainly related to the quality of the oil. You can change the oil from 0w40, and the overall quality is higher than that of 5w40.

I use 0W40 GT Magic Red, which is a PAO fully synthetic engine oil, and the power only decays when driven to 10,000 kilometers, which is much longer than the attenuation period of 5,000 kilometers of general fully synthetic engine oil.

The difference between engine oil 10w40 and 5w40, which is better engine oil 5w40 or 10w40.

The difference between engine oil 10w40 and 5w40 is that the low temperature performance is different, in comparison, engine oil 5w40 is better than 10w40, its cold resistance is stronger, and it can be used in a lower temperature environment. Let's take a closer look.

In order to better understand the difference between engine oil, the premise is to understand the meaning of oil viscosity, where w means winter, which means that the oil can be used in winter. The lower the number, the better the low temperature fluidity, the lower the applicable temperature, and the stronger the cold resistance. The number after w is an indication of the high temperature viscosity of the engine oil, the larger the number, the greater the viscosity of the oil, the better the high temperature protection performance, and the stronger the sealing.

Engine oil 10w40 and 5w40 have the same high temperature viscosity value, its high temperature protection performance is the same, and the difference is in the number in front of w, that is, the low temperature fluidity of the oil is not the same, the applicable environment is different, the oil 5w40 can be applied to the lowest temperature of minus -30, and the oil 10w40 can only be used in the environment above minus -25, 5w40 has better low temperature fluidity than 10w40, cold start performance is better.

From the above description, the available engine oil 5w40 is better than 10w40, and has better low-temperature performance. In fact, car owners only need to choose a suitable viscosity engine oil according to the driving environment of the vehicle, the driving habits of the car owner and the vehicle maintenance requirements.

Engine oil 5w40.

1. Different low-temperature performance: In comparison, engine oil 5w40 is better than 10w40, its cold resistance is strong, and it can be used in a lower temperature environment.

2. The applicable environment is different: the minimum temperature of engine oil 5w40 can be applied to minus -30, while the engine oil 10w40 can only be used in the environment above minus -25, 5w40 has better low temperature fluidity than 10w40, cold start.

Better performance. <>

Precautions. Multigrade oils should be used whenever possible. Multi-grade oil has good viscosity and temperature performance, can be used in the engine for a long time, saves fuel, and is common in all seasons, easy to manage.

When using multi-grade oil, the oil color is easy to turn black, and the oil pressure is less than that of ordinary engine oil, which is normal and does not affect the use.

Domestic brand-name engine oil should be preferred. Domestic engine oil is of high quality and low price (only 50 60 of imported engine oil), and large domestic oil refineries can produce high-grade lubricants that meet international standards, which can be selected with confidence.

The quality of 5w 40 and 10w 40 engine oil is the same, but their viscosity is different, 5w 40 engine oil is relatively thinner, more suitable for winter use, and has antifreeze effect. 10w 40 engine oil can be used as a four-season oil in the south.

Nothing good or bad, depending on what kind of car your car is suitable for, the low temperature fluidity of 5w 40 is a little better, and it is better to use it in winter than 10w 40. It is recommended to use LA zero limit engine oil to improve power and reduce fuel consumption.

5w40 is better, 5w w-30 and so on in the engine oil indicates the viscosity grade of the engine oil, which is the SAE grade. "W" means winter. The best way to improve the power before w is to change the *** fully synthetic engine oil.

The difference between 5w30 and 5w40 is the difference in viscosity. Volkswagen model 40.

The power performance is better than that of the three types of fully synthetic engine oils, the throttle is smooth, the power is fast, the gear shift is sensitive, and it also takes into account the aspects of cleanliness and silence. The anti-recession ability of imported PAO is particularly good, and the recession can only be felt after running 10,000 kilometers, and the maintenance mileage can reach 15,000 kilometers.

Benefits of motor oil:

1. Lubricity. The ability of engine oil to reduce friction, slow down wear and prevent metal sintering under various conditions is called engine lubricity. The viscosity of engine oil is an important indicator of lubricity.

2. Low temperature operability. From the engine oil aspect, the engine oil is easy to start and reliable to supply oil at low temperatures, which is called the low-temperature operability of engine oil.

The difference between these two oils is that the viscosity is different, I have not used these two types of engine oil, I use the best 0W engine oil, the German GT engine oil 0W40 has been used in the family car, it contains liquid molybdenum, outstanding wear resistance, the throttle is particularly light to press, and the acceleration is particularly fast.

The effect of 40 oil is better than that of 30 at high temperatures, and the German engine is running at a high temperature, so the effect of using 40 will be a little better. However, if you want to improve the power, the best is 0W40 imported PAO engine oil, I use the German GT Magic Red, there is no problem with running 10,000 kilometers, and the power is particularly excellent, the sound is low and powerful when running at high speed, and it is particularly cool to use.

How to choose car engine oil? What do the numbers and letters on the oil mean, and what is the difference between 5w30 and 5w40? Let's take a look.

First of all, 5w30 and 5w40 are both all-season universal types and have the same oil cold starting performance.

Then the difference between them is that the kinematic viscosity standard is different at 100 degrees Celsius, which is generally said that the viscosity of 5w-40 is greater than that of 5w-30 engine oil, so that the better the protection performance at high temperatures. The advantage of 5W-30 is that the oil has good fluidity and the fuel-saving effect is relatively obvious.

1. The car series is different:

The choice of engine oil model must be in accordance with the provisions of the car manual, after all, it is not the same engine design of the manufacturer. First of all, let's talk about American cars, American engines are relatively precise (small clearance), so it is most suitable to use 5W-30 engine oil (low viscosity). German cars are usually turbocharged engines, and the gap will be relatively large, so you have to choose 5w-40 (high viscosity) oil.

Japanese and Korean cars use more viscosity oils, while European cars use 40 viscosity.

2. Traffic conditions:

In order to minimize the impact of road conditions on oil life, it is important to choose the right oil viscosity. If you often use the car to commute to work, you will inevitably encounter peak congestion periods, let alone first-tier cities. At this time, we need to change the oil type (5w30) with a lower viscosity, which can greatly reduce the formation of carbon deposits.

If it is often at high speed, the heat and wear of the engine must be more serious, it is recommended to use 5w-40 oil, even at high temperature operation has good oil stability.

3. The age of the car:

The age of the car is also a crucial factor, because with the passage of time, the aging of the engine is inevitable, and the degree of wear is naturally more serious, so it is necessary to change the oil of the model 5w-40 to play a better protective role. For new cars, if the manual stipulates that 30 viscosity is added, then choose a 5w30 oil model.

1. Different applicable temperatures.

1) 5w30: above minus 25 degrees to minus 15 degrees.

2) 5w40: above minus 25 degrees to minus 35 degrees.

2. Different oil levels.

1) 5w30: oil is lower than sn.

2) 5W40: SN grade, SN indication shall not be greater than 35mg; Piston Average Sediment Fraction: SN requires no less than 4 points.

3. Different fluidity.

1) 5w30: It means that the kinematic viscosity is between 9 3 12 5 when it is 100.

2) 5w40: It means that the kinematic viscosity is between 12 5 16 3 at 100 °C.

There are many different grades of engine oil, and different labels indicate different oil properties. Take 5W-30 as an example, 5 means that the temperature applicable to the oil is above minus 25 degrees, if it is 10 means above minus 20 degrees, the smaller the value in front of W, the better the low temperature fluidity. In other words, it is more suitable for northern winter, and has good cold start performance.

W means winter, and the applicable temperature range is relatively large, which means that the engine oil can be used in all seasons.

The value after 5w-30 is the viscosity index, which means that the viscosity index of the oil is 30 in the working state of 100 degrees Celsius, the higher the number, the higher the viscosity, the better the protection of the engine at high temperatures. However, depending on the driving situation and the type of vehicle, it should be filled with the appropriate grade of oil.

The main difference between 5W30 and 5W40 is that 5W-30 has relatively better fluidity and is more capable of reducing fuel consumption and making the engine dissipate heat faster and better. At the same time, for some older cars, the use of 5W-30 will cause the engine noise to be slightly larger, and some strictly require the use of 5W-40 engines and choose to use 5W-30 will cause greater fuel consumption than normal.

At high temperatures, 5W-40 will have better oil stability.

Secondly, the same quality level of engine oil:

The W-30 flows better than the 5W-40, reduces fuel consumption (fuel) more, and dissipates heat from the engine faster. (Low viscosity oils flow better than high viscosity oils).

2. For old cars, the engine noise of 5w-30 oil is slightly louder than that of 5w-40 oil.

3. For engines that strictly require the use of 5W-40, if 5W-30 is used, there may be a situation where the oil consumption is greater than normal (commonly known as: burning oil).

The W-40 has better oil stability than the 5W-30 in the particularly high engine temperatures.

Which is better engine oil 5w30 or 5w40? Many car owners use it incorrectly.

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.

30 and 40 refer to the model of the oil, which has nothing to do with power. If you want to increase the power, you still need to change the oil, not the model. The original oil I used before was also not good, and then I changed the GT Magic Red engine oil after the warranty, and I changed it at 151,000, and the power was abundant during the replacement mileage, and the acceleration and overtaking were smoother than the original oil.

Hello! 10w40 oil, 10w represents -25° can maintain good viscosity, 40 represents high temperature viscosity The higher the value represents the better the high temperature viscosity, I recommend you to change the 5w40 or 0w40 oil, because these two may be semi-synthetic or fully synthetic oil, 10w40 may be mineral oil.

0W40 is the best, 5W40 Secondly, 4S shop maintenance to more than 600 5W40, I bought German GT oil 0W40 is only in the early six00s, the quality is better than 4S shop 5W40, the oil change cycle is extended from 5,000 kilometers to 12,000 kilometers, it is cost-effective to buy oil maintenance by yourself, now there is basically no use of 10W oil, at least 5W, the best is 0W.

The difference between 10W and 5W is the difference in the environment in which the oil is used. 5W is used in extremely cold environments, and 10W is used in warm environments. The following 40 numbers indicate temperature.

If it's summer, 10W is fine, and in winter, it's 5W

The main difference between 10w and 5w is the fluidity of engine oil in winter, and the basic 5w30 belongs to the national four-season oil.

First of all, the oil power experience of 5w40 is better. Secondly, the differences between the two are as follows:

1. Different applicable temperatures.

1) 5w30: above minus 25 degrees to below zero 15 degrees.

2) 5w40: above minus 25 degrees to below zero 35 degrees.

2. Different oil levels.

1) 5w30: lower than sn oil.

2) 5w40: SN level, SN index is required to be no more than 35 mg; Piston Average Sediment Fraction: SN requires no less than 4 points.

3. Different fluidity.

1) 5w30: indicates that the kinematic viscosity at 100°C is between.

2) 5w40: indicates that the kinematic viscosity at 100°C is between.

The difference between 5w40 and 10w40 engine oil is that the environment in which it is used is different, and there is not much difference in use.

W is the abbreviation of winter English has w means that the oil is universal in all seasons, the number behind w indicates the viscosity of the oil, the larger the number of the source family of the number of the town, the thicker the oil, the number in front of w indicates the start-up of the oil, the smaller the number, the better the start-up of the oil, and the minimum temperature applicable to 5w40 should be lower than 10w40.

5w40 oil is resistant to external low temperatures of -30°C, 10w40 oil is resistant to external low temperatures of -25°C, while 5w40 and 10w40 are both resistant to external high temperatures of 40°C. That is to say, 5w40 is more suitable for cold areas in the north than 10w40.

Choice of oil

5w40 is mainly suitable for energy-saving engines with low temperature in the north, low load intensity, medium and low speed, and small compression ratio, and 10w40 is mainly suitable for areas with high temperature in the south, often used in mountainous areas with intense driving and large loads, or suitable for vehicles that travel for a long time.

When choosing the use grade of engine oil, high-grade engine oil can be used on the engine with lower requirements, but it is not economical to use too much downgrade, do not add the lower grade oil to the engine with higher requirements, otherwise it will cause crack resistance to early wear and damage to the engine. The viscosity and temperature performance of multi-grade oil is good, it is used in the engine for a long time, saves fuel, and it is universal in all seasons, easy to manage, when using multi-grade oil, the oil color is easy to turn black, and the oil pressure is less than that of ordinary engine oil, which is a normal phenomenon and does not affect the use.
