How Much Engine Oil Should Be Added During Car Maintenance?

[MasonAnn]

Generally, small-displacement vehicles require 3.2-3.6 liters of engine oil per maintenance, while larger-displacement vehicles need around 4.5 liters. The following introduces the classification of engine oil and its functions: Classification of Engine Oil: Engine oil is divided into three categories: mineral oil, semi-synthetic oil, and full synthetic oil. The replacement intervals for these three types of oil also vary. Generally, mineral oil should be replaced every six months or 5,000 kilometers, semi-synthetic oil every six months or 7,500 kilometers, and full synthetic oil every six months or 10,000 kilometers. Functions of Adding Engine Oil: The quality of engine oil has a significant impact on the working environment of the engine. The engine operates in a high-temperature environment, continuously repeating mechanical friction movements. Engine oil plays a role in cooling, lubricating, and cleaning during this process. Over time, the accumulation of impurities in the oil leads to a decline in its performance.
