How to choose the right oil for your car?

It often happens that you stand in front of engine oil bottles confused and do not know which of them is suitable for your type of car and do not know the difference between them.
But in this article we will talk about the types of oils used and what you should choose.
The types of oil differ according to the degree of viscosity of the oil, because viscosity is the most important component of the oil, as it determines the number of kilometers that the engine can travel, as well as the temperature that surrounds the engine without corrosion in the parts that friction occurs. Therefore, attention must be paid to the degree of viscosity of the oil when purchasing it, and to ensure that it is suitable for the engine.
You can know the viscosity of the engine by reading the mark on the oil bottle, for example, there is 5W-30 number 5Here it means the temperature at which it can operate in the winter, i.e. when the temperature drops and the oil retains its viscosity up to 5 degrees Fahrenheit.
The letter   W also indicates winter and does not indicate weight, as many people think.
The number that comes after the letter W also indicates the temperature at which the oil operates efficiently, which is   30 degrees Fahrenheit and can maintain its viscosity to protect the engine from wear.
When we compare two types of oils, for example 10W-30 and 10W-40 , this means that the bend type works more efficiently at higher temperatures than the first type.
You can look at the user’s manual and find out the appropriate viscosity limits for the car engine, through which the oil can be purchased within these limits so that it works efficiently, so as not to harm the engine. It is also preferable to buy a specific type of oil with a certain viscosity degree so as not to damage the engine and also not to take a lot of time to get used to the new type.
Also, knowing the number of kilometers the oil runs and is highly efficient is essential, so that you know when to change the oil. This helps to maintain the engine and make it last longer. This information is on the oil packaging.
