How often it is necessary to change the engine oil?
It is believed that every 10-15 thousand kilometers. However, not everything is as simple as it seems at first glance. There are a number of specific nuances that can affect the recommended mileage.
The degradation of oil largely depends on the quality of the road surface. Driving on urban roads and the highway is fundamentally different, in particular, it is at least a four-time difference in motor hours. For example, in urban areas, approximately 700 hours of lubrication work will be expended for 30 thousand kilometers, while trips on the highway will require no more than 200 hours. It is important to understand that in different conditions the car engine is exposed to different levels of stress. And the smaller it is, the lower is the load on the oil.
Driving speed has the same considerable effect on engine oil. The higher it is, the stronger the load on the engine is, and hence the oil. Therefore, it is important to maximally maintain the optimum mode for operation of engine and lubrication, which is equal to half of the maximum speed and to minimum operating time at idle after warming up.
If you convert 15 thousand kilometers into motor hours, it equals to 200-700. The indicator depends on the driving mode. In general, it is important to take into account all the criteria as a whole. So the same 400 motor hours under urban conditions at a speed of 20-25 km/h equal to 8-10 thousand kilometers per one portion of oil, while an increase in speed to 80 km/h equals to 32 thousand kilometers.
Type of oil
Of course, the frequency of engine oil change depends on the specific type. Therefore, you should definitely follow the recommendations of the manufacturer and the operating conditions of the vehicle, including the climatic ones. Deviation from standards is fraught with premature wear of vehicle parts.
In conclusion, it should be said that the determination of the optimal frequency of engine oil change is individual and requires consideration of all the above factors. That is, for example, if the road surface you have to drive on leaves much to be desired, or there is a ride at a speed that exceeds the average figure, the engine oil definitely needs to be changed more often.
