Buy Base oil 8cst
Group 3 base oils have better characteristics than the previous two oils and are better for new machines. Motor oil and greases obtained from this oil are far better and more effective. In this article, we are going to introduce one of the base oils of the third group. base oil 8cst In the future, group 3 oils will be expanded and the base oil of group 1 will be removed from the market. In the following, we will examine the specifications and uses of this oil.
What is base oil 8cst?
Many products can be extracted from crude oil, one of which is this oil. To produce this oil, crude oil is first refined, then solvent purification is used for purification. In the next step, in order to separate unnecessary elements such as nitrogen, oxygen, and sulfur, they use the purification method with hydrogen and catalysts. The first two steps are used to produce the first and second group base oils, and the third group base oils are obtained by performing the third stage. In addition to purifying the final product, the third step improves its characteristics, including viscosity index and antioxidant properties.

After the industrial revolution and the development of advanced machines, lubricants are felt more. With the updating of industrial machines, oils and lubricants should be purer and have better specifications. Base oils of the second group were purer than the first group and had better characteristics. Over time, machines came along that needed better oil, and base oil Group 3 became an excellent proposition.

Benefits of base oil 8cst
The advantages of this oil according to its characteristics are:
1- Proper fluidity at low temperatures:
At low temperatures, the movement of molecules and atoms slows down. Adequate flowability at low temperatures is an important issue. This oil flows well at low temperatures.
2- Having antioxidant properties:
The antioxidant property means that there are few free molecules in this oil, which causes them to react with oxygen. The reaction of free molecules with oxygen causes internal friction in the oil. Internal friction has a negative effect on oil performance.
3- Low volatility:
Resistance to evaporation at high temperatures is one of the important features of any oil. If the oil evaporates at high temperatures, the operator has to add oil again. 8cst oil does not evaporate at high temperatures and there is no need to add oil to the machine again.
Applications of Base oil 8cst
Base oil 8cst are highly valued across various industries due to their superior properties. Key applications include:
Base for Lubricants: The excellent characteristics of Group III base oils make them an ideal foundation for formulating a wide range of automotive and industrial lubricants. Their inherent properties often require minimal additive adjustments.
Additive Component: In certain formulations, this oil can be incorporated to enhance specific performance attributes, tailoring the final product to precise requirements.
Functional Fluids: These oils serve as essential components in concentrated functional fluids. When diluted with water, they create solutions for cooling, lubrication, and corrosion prevention.
