What model of summer engine oil to use? Are there any limitations to choosing an oil?

Summer oil selection should pay attention to, high temperature, oil viscosity grade is wrong, high temperature will be unstable, I bought German GT oil, low temperature and high temperature have no effect, or very good, low temperature fluidity and high temperature stability compared with the current famous brand of engine oil have certain advantages, especially like low temperature, the pour point can reach minus 50 degrees.

The Gold Mobil 1 0W-40 is more suitable for turbocharged engines, and the main focus of Mobil 1 is protection at high revs. The gray shell focuses on clean engines, while Castrol EDGE focuses on cold start protection, and each has its own strengths depending on your choice.

There are three types of engine oils: summer, winter, and seasonal oils.

The oil grades used in winter are: 0w, 5w, 10w, 15w, 20w, 25w, the symbol w represents winter is the abbreviation of winter (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;

The general oil grades in winter and summer are: 5w w w w

1) High temperature type (such as SAE20 SAE50): The number indicates the viscosity at 100, and the larger the number, the higher the viscosity.

2) Low temperature type (such as Saeow Sae25W): W means only used in winter, the smaller the number, the lower the viscosity, and the better the low temperature fluidity.

3) All-weather type (such as SAE15W W 50): It means that the viscosity grades at low temperature meet the requirements of SAE15W, 10W, and 5W, and the viscosity grades at high temperature meet the requirements of SAE respectively, which belongs to the general type in winter and summer.

In summer, 10W-40 or 10W-30 engine oil is generally used, and the oil model will be marked on the oil bottle.

When using the car in summer, under the condition of ensuring lubrication, according to the temperature range, engine temperature and actual vehicle conditions at the time of use, choose engine oil with low viscosity as much as possible. For engines with better vehicle condition and less wear, you can choose an oil with low viscosity, such as 5w-30 or 10w30, and for an engine with serious wear and a relatively large clearance, you can choose an oil with a slightly higher viscosity, such as 10w-40.

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.

In the case of Shellhelix Supermotor Oil, the most typical figure is SAE10W 40.

The oil grades used in summer are respectively, the larger the number, the greater the viscosity, and the higher the applicable maximum temperature; The winter oil grades are: 0w, 5w, 10w, 15w, 20w, 25w, the symbol w represents the abbreviation of winter (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 specific classification of automobile engine oil is 4 kinds of summer oil, 6 kinds of winter oil, and 16 kinds of winter and summer general oil. There is also a general oil for winter and summer, the grades are: 5w w w w w

Precautions for the use of engine oil.

It is necessary to pay attention to the conditions when there is a qualitative oil change; When there is no condition, the oil can be changed according to the oil change mileage recommended in the instruction manual or specified by the model. Do not mix oils produced by different specifications and manufacturers. Because different engine oil additives have different compositions, they are easy to form precipitates when mixed together, which is not good for engine lubrication.

In order to prolong the service life of the oil, the old oil should be cleaned when changing the oil, and the lubrication system should be cleaned. When the engine is working, the crankcase ventilation device should be kept good, and when adding new oil, care should be taken not to let impurities and moisture mix. The oil change should be accompanied by a replacement of the filter element.

Since winter and summer general purpose engine oil has become the mainstream, we no longer need to change the corresponding engine oil at the turn of winter and summer. The labels of winter and summer general purpose engine oil are 5w w w w

5W40 SL and 10W40 SL are common in winter and summer, and are common in the north and south, which is a pure synthetic lubricating oil.

5w50 sl, 5w60 sl, 10w50 sl, 10w60 sl and other oils are too viscous and cannot be used in winter, so they are suitable for other seasons other than winter.

If your car is a gasoline engine of about 100,000, it is recommended that it is more cost-effective. If the winter temperature is higher than -20 degrees in your area, then there is no problem with the use of this oil in winter.

I'm using GT Magic Red oil, which is really good, and I feel like the driving experience is the best after using so many oils. The quality of PAO engine oil is much better than that of semi-synthetic engine oil, the driving experience will be better, the driving force is particularly strong, the oil is ester in it, and the power is very good, and it is very easy to drive the more difficult roads.

To change the engine oil in summer, whether to improve the label to protect the engine, many old drivers do not understand.

Cars are not the same as cars, and different regions are not the same.

If it is a general turbocharged engine, you can use 5w30 oil; If it is a high-performance turbocharged engine, 5w40 oil can be used. If it is a naturally aspirated engine, you can use an oil with a viscosity of 20 or 30.

Generally speaking, 5w30 engine oil can be used in summer. This kind of engine oil has good fluidity at low temperature, low viscosity mold dust, more fuel efficient, and can be used in summer.

In the oil label, the number in front of W represents the low-temperature fluidity of the oil, and the lower the number, the better the low-temperature fluidity. The number after w represents the viscosity of the oil. The higher the value, the greater the viscosity and the better the sealing performance. The smaller the imitation value, the smaller the viscosity and the more fuel-efficient.

In general, low-temperature and well-flowing oil should be used in winter to prevent it from flowing in the engine and reduce its lubrication, cooling and cleaning effectiveness. In summer, you can choose a low-viscosity oil that is easy to start the car.

In summer, 10W-40 or 10W-30 engine oil is generally used, and the oil model will be marked on the oil bottle.

How to choose engine oil in summer is what car owners need to know. The impact of high temperature on engine oil is still very large. Choosing the right oil can have a significant impact on protecting your engine.

When using the car in summer, under the condition of ensuring lubrication, choose an oil with low viscosity as much as possible according to the temperature range, engine temperature and actual vehicle conditions. For engines in good condition and low wear, you can choose an oil with low viscosity, such as 5w-30 or 10w30, and for engines with serious wear and large clearances, you can choose a slightly more viscous oil, such as the abbreviation of the Society of Automotive Engineers of the United States, SAE grade represents the viscosity grade of the oil. SAE30 and SAE40 are single-grade oils, and SAE 10W-30 and SAE 15W-40 are multi-grade oils.

Among them, the smaller the previous value, the lower the low-temperature viscosity, and the better the protection ability of the engine during cold start. "w & quot The latter figure is an indicator of the high temperature resistance of the engine oil. In the case of Shell Helix oil, the most typical data is SAE 10W-40.

The distinction between winter and summer engine oil is mainly based on the viscosity grade of the engine oil, that is, the engine oil label. Winter oil is mainly based on the low-temperature fluidity of oil, of which 0w, 5w, 10w, 15w, 20w, and 25w are all expressed as winter oil. The oil used in summer mainly refers to the viscosity grade of the oil at 100, and the viscosity grade at 100 is the summer oil.

With Castrol or Shell. The level is 5w30. This oil is an all-season motor oil. The flow performance at low temperatures is particularly good. The engine runs with little resistance. So it's fast and fuel-efficient. **Also very affordable.

The temperature in the summer is relatively high. When choosing an oil, you can use an oil that is more viscous than usual. If cars usually use 20 viscosity oil, 30 viscosity oil can be used in the summer. If the car usually uses 30 viscosity oil, 40 viscosity oil can be used in the summer.

However, in the summer, you can also use the same viscosity as usual, and the rider only needs to maintain and change the oil on time.

Engine oil is known as the blood of the engine and plays a role in the engine for lubrication, heat dissipation, sealing, cleaning, buffering, and rust prevention.

If the engine is without oil, the engine will not work properly.

Common engine oil models are 0w, w, w40, etc. The W in the oil model number is an abbreviation for winter, which means winter. If there is a letter w in the oil model, it means that the oil can be used normally in winter.

The number in front of W represents the low temperature fluidity of the oil, 0W means that the oil can flow normally at minus 35 degrees Celsius, and 5W means that the oil can flow normally at minus 30 degrees Celsius.

The number after w indicates the high temperature viscosity of the oil, and the higher the number, the greater the viscosity.

When buying engine oil, you should choose the right viscosity, and the viscosity should not be too high or too low. Too high viscosity will increase the resistance of the engine during operation, and too low viscosity will lead to poor engine lubrication.

Nowadays, there is a general purpose engine oil for winter and summer, so there is no need to change the corresponding engine oil at the turn of winter and summer. The labels of winter and summer general purpose engine oil are 5w w w w I believe that many car owners will do regular maintenance on their cars.

The maintenance and replacement of engine oil and oil filter element machine is a must-have for car maintenance:1. Engine oil is the lubricant that runs the engine.

It lubricates, cleans, cools, seals, and reduces wear and tear on the engine. This is of great significance to reduce the wear and tear of engine parts and extend the service life.

2.The oil filter cartridge machine is a component used to filter engine oil. The oil is rich in certain colloids, impurities, water and additives; During the working process of the engine, the metal chips formed by the friction of various parts, the impurities of the suction sail leather into the air body, and the oil oxides.

They are all filtration targets for oil filters. If the oil is not filtered, it will directly enter the oil circulation, which will adversely affect the function and service life of the engine.

Millions of car purchase subsidies.
