The change interval for fully synthetic motor oil is usually recommended to be changed every 10,000 to 12,000 km or every 6 months. However, this cycle can be adjusted appropriately on a case-by-case basis.
If the vehicle is frequently operated in harsh environments, such as dusty environments, low temperatures (below -20 degrees Celsius) or frequent short drives (less than 8 km at a time), oil changes may be required. In addition, if the vehicle has not been started for a long time (e.g. more than 3 months), a new oil change should also be considered.
Motor oil plays an important role in lubricating and protecting vehicles. It can reduce the friction and wear of the metal parts inside the engine, reduce the heat generated by friction, and effectively clean the impurities and carbon deposits inside the engine. Over time and with the accumulation of use, the oil gradually loses its lubricating properties and cleaning ability, so it needs to be replaced regularly.
In addition, frequent short drives can also have an impact on the oil. Short distances mean that the engine does not have enough time to reach its normal operating temperature, which can cause the oil to not flow and function adequately. Therefore, if your vehicle is frequently engaged in short trips, it may be more appropriate to change the oil every 5000 to 8000 km.
Finally, if the vehicle has not been started for a long time, you should also consider changing the oil again. Leaving it unstarted for a long time means that the oil stays inside the engine for a long time, which can be affected by oxidation and pollution. Therefore, it is advisable to change the oil in time after the vehicle has not been started for a long time.
