Types of car oil

Car oil is necessary for the operation of any car. One of the important parts of a car is its engine. When the engine does not work well, the car will face a lot of problems and will generate a lot of repair costs. Therefore, car owners attach great importance to the quality and health of the engine. One of the things that must be done to take care of the car engine is to use the right oil. Engine oil must have a series of standards. In this article, we will mention its different models, so stay with us. Let's drive a car to know why it is so important. The engine has many parts that create friction between them; Wherever there is friction between parts, heat is generated. The heat weakens the parts and makes their operation difficult; The presence of engine oil makes the friction between them less and the wear of the parts is eliminated. In addition, repairing and replacing worn parts of the engine costs money; Therefore, if you choose a suitable engine oil. On the other hand, another feature of engine oil is to reduce rust. During fuel, it combines with oxygen, and oxygen is the cause of rusting of metals; Engine oil prevents oxygen from reaching the engine and minimizes rust. It is one of the most important factors in choosing engine oil. Viscosity, which you have probably seen in textbooks, is called thinness or incorrectness of the liquid, if I want to give a simple example, water has a low viscosity, while jam has a high viscosity and is thick. For the engine to work well; The engine oil must have a suitable viscosity. Hence the rating called SAE was created to help you choose the right viscosity grade for your engine oil. SAE stands for Society of Automotive Engineers and its rating ranges from 0 to 60 degrees. In this grading, you will encounter numbers from 0 to 25, which is for winter and cold weather, and a number between 30 and 60 degrees for hot and summer weather, each of which is divided into single grade and multi grade models, which single grade is Viscosity is said to be a single number as its SAE is 30, which means this oil model is not good for four seasons and is only for cold or hot weather. If multi grade is used for engine oils that are suitable for 4 seasons. This model of engine oil has a series of polymer additives that do not need to be changed. It is compatible in every season.   Motor oil has different models in terms of viscosity. The most common model is 10 W-40, the use of this engine oil in the hot seasons of the year causes the oil to stick to the internal parts of the engine when the temperature rises and does not allow the parts to wear. 10W engine oil -40 and 20W-50 These two models of engine oil are the most widely used, which have differences. 10W-40 engine oil for low grade air; If 20W-50 engine oil is suitable for high temperature. The reason for the difference between the two is that the first engine oil is faster and its viscosity is low, and it goes easily between the engine components and starts the engine earlier in cold weather; If the second motor oil is the opposite of the first.   Production is classified into three models. The first model is a fully synthetic engine oil that is exploited in the laboratory using chemicals and has optimal performance and increases fuel consumption efficiency.This model of oil has a higher price than others, and the word FULL SYNTHETIC is written on its bottle; This model of oil has full and perfect performance for any car engine. Semi-synthetic engine oil is the second category, which is produced from the combination of normal and synthetic oil; The price of the oil is not full synthetic. 10W-50 motor oil is part of this oil category. The normal motor oil is the third category, which is based on crude oil and is cheaper than others and usually for cars Their design is not complicated or they have zero efficiency. This type of engine oil is not suitable for very cold weather because it cannot protect the engine, and it is the same in hot weather. When using this type of oil, you should change it after 4 thousand kilometers of operation, which is usually not recommended because of its costs and the inefficiency of suitable engine oils.
