Owners know that regular replacement of engine oil is an important item in car maintenance, so how often is it considered regular? If you talk about it in detail, there are three kinds of engine oil replacement standards: one is based on the mileage of the vehicle (or the working hours of the engine), which is what we often say about regular oil changes. One is based on the degree of change in the performance of the engine oil, called quality oil change. In addition, there is another one that determines whether the oil should be replaced according to the display of the oil quality detection instrument. Although the latter two methods are more accurate, the cost is higher and more troublesome, so now people are mostly based on experience to determine the replacement cycle of engine oil, even if the replacement time or mileage marked by the manufacturer's manual is only an approximate number.
Therefore, how often to change the oil should also be determined by you according to the specific car conditions, referring to the car's manual. For example, you are driving a new car, with a higher level of good oil, basically can travel 10,000 to 20,000 kilometers and then replace the oil. If your car is in bad condition and the driving environment is general, it is necessary to shorten the cycle of oil replacement, such as replacing the oil every 5,000 to 10,000 kilometers.
