How Many Liters of Engine Oil Should Be Added?

[VonLawson]

It is generally appropriate to add 3.5 to 5.0 liters of engine oil during maintenance. Here are some details about engine oil: Classification of Engine Oil: Automotive engine oil is divided into three types: mineral oil, semi-synthetic oil, and full-synthetic oil. Mineral oil is the most basic and cheapest type, usually classified below SJ grade, and is only suitable for low-end vehicles or some new cars. Functions of Engine Oil: Lubrication to reduce wear: There is rapid relative sliding between the piston and cylinder of the engine, as well as between the main shaft and bearing bush, which can easily cause wear. High-quality engine oil can form a sufficiently thick oil film between the two sliding surfaces, separating the relatively sliding parts and thereby reducing wear. Cooling: Engine oil can carry heat back to the oil tank and then dissipate it into the air, helping the radiator to cool the engine.
