What are the lubricating oil classes?
Lubricating oil is engines, what is blood for the human body. Like different types of blood found in different bodies, there are different classes of lubricating oil, each of which serves for a significant purpose. Synthetic and semi -synthetic oils are the most common classes of lubricating oil. In each of these classes, oils are divided into other classes for commercial classes and services.
engine oil and raw oil are not the same. It would be impossible to operate the engine or maintain metal joints properly lubricated with strong black oil from the ground. Initially, engine oil and lubricating oils were made from the by -product of the oil refinement process, but for most situations it turned out too unreliable. For this reason, synthetic oils have been developed to imitate the lubricating properties of the oil and at the same time eliminate its tendency to give and fail. Two different classes were born with this invention: synthetic oil and semi -synthetic oil.
synthetic oil chemically changes make -up oil, especially to improve its consistency.This class of lubrication oil can be calculated to keep moving parts safe during a long range of use. This oil class is sought in extreme weather conditions because its chemical structure allows it to function reliably in cold or hot climate. One of the largest users of purely synthetic oils is the air industry because the engine turbines require this class oil.
More common lubricating oil is a semi -synthetic class. Purely synthetic oils are usually relatively expensive, but semi -synthetics are more accessible. It stems from its composition; It consists of 70 percent of mineral oil and the rest is synthetic oil. This oil provides excellent lubrication to moving parts, but suffers from lower performance and reliability. These oils are found in multiple domestic products, such as JOOKO of lawns or cars.
These two primary classes are further divided according to their use. OilE served class C signs are considered commercial lubrication oil. This applies to the ignition of the engine compression, usually found in diesel engines, and is created to withstand the voltage of commercial use. The S -Class oils are reserved for lubrication of the service class associated with cars and trucks that operate using petrol engines. These classes are created by government councils in many countries, such as the US oil institute in the United States.
