How Many Liters of Engine Oil Are Needed for Maintenance?

[McDante]

When performing maintenance on a car, the amount of engine oil to be added depends on the type of engine. Generally, small-displacement vehicles require 3.2-3.6 liters of engine oil per maintenance session, while larger-displacement engines need approximately 4.5 liters. Changing the engine oil ensures the normal operation of the engine and also provides sealing to prevent leaks, as well as protection against rust and corrosion. Although under normal circumstances, the consumption of engine oil is minimal, the oxidation of esters and polyolefins in the oil, along with wear particles from engine components entering the oil, can reduce the oil's lifespan and cause internal components to degrade. Therefore, regular replacement during maintenance is necessary. When adding engine oil, it is important to ensure that the amount added is slightly below the mark on the dipstick. Exceeding the upper limit on the dipstick can increase the rotational resistance of the crankshaft and reduce the engine's output power.
