What does the oil label mean? Will the marking be different for different car models? What car shoul

There is a difference in the viscosity of different engine oils in the car series, but DU has nothing to do with the quality of the car itself, you will send the first insurance dao after you buy the car, the first insurance is the original engine oil of the 4S shop, generally 5W marking, the quality is not very good, the power is insufficient to run more than 3000 kilometers, you can buy your own oil after use, I Langyi uses the magic red 0w40 engine oil imported from Germany, PAO oil power enough to run is a good driving experience, and more than 10,000 kilometers can be changed once.

The label after the classification of the engine oil indicates its viscosity specifications, for example, in "15w w-40", "w" means winter (winter), the more ** the number in front of it, the better the low temperature fluidity of the engine oil, the lower the ambient temperature available for use, and the better the protection ability of the engine during cold start, such as 5w represents the external low temperature resistance -30 °C, and the 20w low temperature resistance is -15 °, and the number behind the 20w low temperature resistance is -15 ° represents the kinematic viscosity of the oil at 100, the higher the value, the higher the viscosity. 40 represents the kinematic viscosity standard at 100 degrees Celsius.

There are differences in the viscosity of different engine oils, but it has nothing to do with the quality of the car itself, you will send the first insurance after you buy the car, the first insurance is the original engine oil of the 4S shop, generally 5W marking, the quality is not good, the power is insufficient to run to more than 3000 kilometers, you can buy your own oil after use, I use GT magic red 0W40 engine oil, PAO oil power is a good driving experience, and you can change it once for 15,000 kilometers.

Personal opinion: There are two main parameters for the oil label, one is the temperature coefficient, which is selected according to the minimum temperature of the place where the car is located; One is viscosity, this parameter should not be played by yourself, it is best to choose according to the viscosity on the manual, and the old car can also increase the viscosity slightly according to the actual situation.

The oil designation usually indicates viscosity and quality. The specific interpretation is as follows: the viscosity of lubricating oil is mostly marked by SAE and other grades, and SAE is the abbreviation of the English "Society of Automotive Engineers".

Take 10W-40 as an example, "W" means winter, the number 10 means that this oil is suitable for the minimum external temperature of -25, and the number 40 means that it is resistant to external high temperature of 40.

For example: SAE5W-40, where "W" represents Winter, and the number in front of "W" represents the flow viscosity of Ming Min Qiao at low temperatures. The number after the "w" is the viscosity of the oil at 100, the higher the number, the higher the viscosity.

The designation on the motor oil is based on the American Society of Automotive Engineers (SAE) oil viscosity classification.

This is a viscosity classification that divides lubricants into high-temperature types for summer, low-temperature types for winter, and all-weather types for winter and summer.

The specific classification of lubricating oil is 6 types of winter oil, 4 types of summer oil, and 16 kinds of winter and summer general oil.

1.Shell lubricants 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, the lower the applicable minimum temperature;

2.The grades of Shell lubricants used in summer are as follows, the larger the number, the greater the viscosity, and the higher the applicable maximum temperature;

3.Winter and summer general Mobil Hongchun lubricant grades are: 5w w w w 40,

10w w w w w 50, the smaller the number representing the winter part, the larger the number representing the summer part, the higher the viscosity, the larger the applicable temperature range.

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 W 50): It means that the adhesion defect level at low temperature meets the requirements of SAE15W, 10W and 5W respectively

The viscosity grades at high temperatures meet the requirements of SAE respectively, and belong to the winter and summer general type. There is no problem with 5w-30 engine oil in Sichuan.

The label of motor oil means to indicate viscosity and quality. The engine oil label includes two parts: grading and viscosity specifications, and the graded label indicates its viscosity specification, the difference is that it is divided into a high-temperature type for summer, a low-temperature type for winter and an all-weather type for winter and summer.

The oil label consists of two parts: grading and viscosity specification. The oil designation usually indicates viscosity and quality. The specific interpretation is as follows:

The viscosity of lubricating oil is mostly marked by SAE and other grades, and SAE is the abbreviation of the English "Society of Automotive Engineers". w stands for winter (winter), the more ** the number in front of it, the better the low temperature fluidity of the engine oil, the lower the ambient temperature available for use, and the better the protection ability of the engine during cold start; The number after the "W" (after a horizontal line) 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.

The oil classification is indicated using a two-letter combination. The series starting with "S" represents gasoline engine oil, and the general specifications are from SA to SN, with each letter incremented, the performance of the engine oil will be better than the previous one, and there will be more additives in the oil to protect the engine; The lower the letter, the higher the quality grade, and most of the oil grades in international brands are above the SF grade. The series starting with "C" represents diesel engine oils.

If the letters "S" and "C" are present at the same time, it means that the oil is a general purpose type of gasoline and diesel.
