The lubrication system is essential for the proper functioning of the engine, therefore the periodic checking of the oil in the sump with the help of the oil dipstick is recommended. The correct level of the oil in the sump must be between the minimum and maximum marks on the oil dipstick. And the change of the oil and of the filtering element (the oil filter) is done at a certain number of kilometers travelled, specified by the manufacturer of the motor vehicle, or according to the validity period of the oil.
The engine oil loses its properties due to wear from use but also through wear from time. Even if the number of kilometers specified in the service manual is not completed but the time interval is exceeded (the oil expires), it must be replaced. Once the oil is replaced, the oil filter will also be replaced.
The correct answer is: A
