Changing the oil is the most important element of car maintenance. Engine oil enables the engine to be lubricated and cooled, which is essential for proper and long-lasting engine operation. Engine oil is an integral element of every internal combustion engine, which is especially consumed when driving short distances, especially in the city. It is recommended to change the oil filter when changing the engine oil. The role of the filter is to clean the engine oil from micro-pollutants, which affect the operation of the engine.
