Motor oil 5W30

For most modern gasoline and diesel internal combustion engines, the technical characteristics of Motor oil 5w30 are optimal. This product is designed to lubricate assemblies and parts, remove excessively high temperatures inside the unit, and minimize the effects of friction between moving and stationary parts. It is quite simple to choose a product; manufacturers offer many options for such an oil.


 


To ensure long-term and efficient operation of such a complex mechanism as an internal combustion engine, it is important to provide high-quality care for it. The motor is made up of many individual parts that operate under extreme temperature conditions with constant friction. All this inevitably leads to gradual wear of the power unit.


In order for the engine to work as long as possible and not cause any problems to the car owner during operation, it is important to provide high-quality care and regularly refuel the lubrication system with 5W30 engine oil.


 


Decoding of marking 5W30


First of all, it should be noted that the marking, which allows you to quickly determine the main characteristics of the lubricant, is carried out according to the generally accepted international SAE classification.


The product is all-season, which is the reason for the highest popularity among motorists. In fact, the versatility of the oil indicates its suitability for use in engines running on a variety of fuels. And the temperature range of application covers almost all climatic zones of our country.


 


More about the characteristics, decryption features


The quality of the lubricant is directly influenced by 2 main parameters: viscosity when exposed to negative and positive ambient temperatures.


Let's consider them sequentially:


 


- Low temperature viscosity.


The parameter is important for the engine of any machine, since it shows that the lubricant is somewhat capable of being on the surface of parts for a long time. This property of the substance is coded as "5W", where the letter indicates the possibility of use in winter conditions:


W– winter. It is known that at low TS values, oil, like other liquids, thickens.


 


- High temperature viscosity.


The parameter indicates the other half of the label. So, in accordance with the established SAE classification for a given brand of oil at a temperature of 100 ° C, the viscosity index will be in the range of 9.3 - 12.6 mm kV / s. Another parameter that is characterized by high-temperature properties is the minimum viscosity at shear rate (106 s-10. For this product, this parameter does not exceed 2.9.


 


Having figured out the parameters, you can decipher the 5WЗ0 engine oil easily and quickly.


 


Features of practical application


When deciding on the use of a particular product in the lubrication system, it is necessary to understand that for cars with different years of production, experts give individual recommendations on the choice of oil. As for the 5W 30 brand, it should be used if the service life of the car is more than 7 years, and the mileage has not exceeded the mark of 70 thousand km. If these values are exceeded, an oil with a higher high-temperature viscosity should be used: 5W40.


 


When choosing in favor of 5W30 oil, in addition to the degree of engine wear and resource development, you should pay attention to the following indicators:


- Power unit type;


- How intensively the vehicle is used;


- Feature of road and climatic conditions;


- The presence of additives that improve the physical, mechanical and operational properties of the product.


 


 


Summarize


The use of 5W30 engine oil in car lubrication systems in temperate climates, as well as in arctic (subarctic) temperature drops, shows all the advantages of using the product. Thanks to the unique development of chemical engineers, it was possible to produce a high-quality product, and to provide the highest level of concentration of all necessary components to achieve excellent stability indicators, both chemical and thermal!
