What is base oil 6cst?
base oil 6cst is one of the examples of the third group of oils. This oil is extracted from crude oil. After crude oil refining and solvent purification, oxygen, nitrogen and sulfur elements are separated from crude oil by means of hydrogen gas and catalysts, and finally pure oil is obtained. base oil 6cst is known for its antioxidant properties and flowability at low temperatures. This makes this oil to be used to make secondary solutions. The price of this product is higher compared to group 2 and 1 base oils because its extraction process is more complicated than the previous two oil groups.

The development of science and technology made new products available in the market that are better than the previous products. In fact, the needs of people or industrial industries cause the production of industrial products. In the industry sector, the number of machines that are operating every day is very high. One of the requirements of these machines is proper lubrication.
What is the use of 6cst base oil?
With the efficiency of Group 2 base oils, the temporary needs of some industries were solved, but there were still machines that needed better quality oils and greases.with advancement of machinery in industries, the market for Group 2 base oils is decreasing and Group 3 base oils are becoming more prosperous. Group 3 base oils were recommended for machines that needed purer oils and greases with better viscosity index and antioxidant properties. Undoubtedly, it can be said that the expansion of this group of oils will be a transformation for production and industry.
In the following, we intend to introduce one of the samples of base oil group 3, base oil 6cst. To learn more about this oil, we will first provide a definition for it and then go to its specifications and uses.

Benefits of base oil 6cst
The advantages of this oil according to its characteristics are:
1- Proper fluidity at low temperatures:
Maybe the car or the machines that are used, start working in cold weather conditions. This oil does not lose its fluidity in difficult conditions and does not cause problems when starting the machine.
2- Having antioxidant properties:
The reaction of free oil molecules with oxygen causes the oil to develop internal friction. Internal friction affects the characteristics of the oil and may change the fluidity of the oil. base oil 6cst is saturated, which means that the free molecules in this oil are much less than the previous two groups and it does not react with oxygen, so its fluidity does not change.
3- Low volatility:
This oil does not vaporize at high temperatures and you do not need to continuously add oil to the machine during the process.
Applications of base oil 6cst
As the characteristics of this oil are different from other groups. Group 1 and 2 oils had many applications, but for sensitive and specialized applications, group 3 base oil should be used. Some applications of Group 3 base oil include:
1- Basic composition for making all kinds of car and machine oils
Cars and industrial machines need oils that have special characteristics. The characteristics of base oil 6cst are close to the required final specifications, so they use this product as a base oil to make the final oil.
2- An additive to some compounds
They may use it in some situations to bring the characteristics of the solution to ideal characteristics. In fact, its role in these solutions is to adjust the final specifications.
3- functional fluids
Functional fluids are solutions that are often concentrated. To use these products, you must first mix a certain amount of it written on the catalog or guide sheet with water. After some time, this solution can be used. This product is mostly used for cooling, lubrication and preventing corrosion.
4- Production of lubricant and grease
High quality greases are made from group 3 base oils. These greases are used to lubricate bearings, shafts and gears. These oils are often used to lubricate car gearboxes and machines.
5- Making paint and resin
To prevent rusting of the metal surface and to have a beautiful appearance, the metal surface is painted. In fact, paints prevent rusting by creating a coating layer. They use third group base oil to make colors. The reason for this is the anti-rust property of this product.
6- springs oil
Springs are installed to reduce transfer shock. springs need to be lubricated. 6cst oil is considered as a suitable option for lubricating springs due to its good viscosity at different temperatures.
The price of base oil is 6 cst
The price of petrochemical products is determined based on the spot price of crude oil. The current price of crude oil is not fixed, so it is not possible to consider a specific price for this product.
