Engine oil in the engine requires periodic replacement (according to maintenance plan, see below), every 15,000 km or every year of operation of the vehicle, whichever comes first.
When choosing engine oil, follow the manufacturer's recommendations. During the warranty period of the car, you must use only the recommended brand and type of oil. The life of the engine depends on the quality of the oil, so do not save on oil and oil filter and replace them in a timely manner.
