what is Base Oil SN150?
SN150 base oil is an excellent choice for lubricants and additives. Base Oil SN150 is known as the base oil for making all kinds of lubricants and engine oils. This oil is one of the examples of group 1 base oils and is the result of refining crude oil with solvents. The high quality of the base oil makes lubricants more efficient. Do you know what factors increase the quality of Base Oil SN150? In the following, we intend to answer this question in addition to stating the benefits of this product.
BASE OIL SN150 is a cheap product compared to other derivatives
By refining oil, oils of different quality and efficiency are obtained. These oils are divided into 5 categories.
- Group I
- Group II
- Group III
- Group IV
- Group V
The difference between each of these categories depends on the degree of saturation, the amount of sulfur in the oil and its viscosity level.
In the first group, the saturation level is less than 90%, the sulfur content is above 0.03%, and the viscosity level is 80 to 120 millipascal seconds. Products of this group are cheaper than others due to less saturation and higher sulfur levels. The main uses of this group of oils are:
1- Production of oils for cars and trucks
2- Preparation of lubricants for all kinds of industrial, agricultural and transportation machines
3- Production of grease with different concentrations
4- Production of liquids needed for metal polishing machines
In the industries that need this type of product, several indicators are considered as the main indicators.

Important indicators for choosing the right base oil
1- Stability of chemical and physical properties during operation
Engines of cars and industrial machines operate at high temperatures; This makes the oil used for lubrication to have the required stability at high temperature and pressure. Poor quality oils are decomposed and evaporated due to high temperature and pressure.
2-High ignition point
High heat causes poor quality oils to work. Base Oil SN150 is one of the oils that can withstand high heat and has a high ignition point.
3- Optimum oxidation and thermal stability
High heat causes oil and oxygen to combine. This leads to sequestration and dissolution of oil. Base oils Group 1 have good oxidation stability and over time their oxidation rate increases less.
Factors to increase the quality of Base Oil SN150
So far we have discussed the introduction and benefits. Here we intend to answer the first question. In order to find out the factors that increase the quality, we must first look at the ingredients of this liquid. SN150 oil is a combination of crude oil, normal paraffins, polar compounds, isoparaffins.
The amount of paraffin in the composition of oils increases the quality of the oil.
Also, the higher amount of isoparaffins in base oils increases oxidation resistance and thermal stability.
What should be the concentration of Base Oil SN150 ingredients?
The concentration of polar compounds should be normal and its low and high depends on the conditions. A suitable amount of polar compounds leads to heat transfer and protection of metal surfaces against corrosion and erosion. But a large percentage of it causes oil deposition and blocks the oil passage valves.
Another important factor is the amount of sulfur in these oils. The high amount of sulfur causes high friction and causes wear with metal parts over time. In addition to external friction, it causes internal friction that reduces the amount of oil lubrication.
purification process
The refining process is one of the important factors in increasing the viscosity of group 1 base oils. The refining process of base oils includes various steps such as separation of impurities, hydrogenation and refining with solvents. Defects in any of the steps will reduce the quality. BLACK WATER company is continuously measuring the quality level of oils using accurate devices.
Oil quality control at each stage is the last important thing in determining oil quality. At each stage, the quality of the oil must be evaluated so that the specifications of the processed oil match the desired technical specifications the most. This company fully supervises the refining process in cooperation with experts and expert engineers.
