The maintenance habit of a vehicle depends on how the owner cares for the car. If you buy a second-hand car, the first priority is to change the oil in the car, because the various fluids in the car system are like the blood of the human body. The same is the source of the power of life. Therefore, after buying a second-hand car, it is necessary to replace the previous car fluid to create a new “blood system” for the car.
And in this link, changing the oil is the most important. Motor oil is the blood that maintains the life of the engine, and plays the role of cooling and lubricating engine components. New owners can choose the right oil according to their driving habits. It should be noted that when replacing the oil, the oil separator should also be replaced to ensure that the oil circuit is smooth and not blocked by impurities.
In addition, the “blood” to be replaced includes gearbox oil, brake oil, water tank cooling water, water splash glass water, etc. Gearbox oil is the most easily overlooked item. It is recommended that after driving a second-hand car, the owner should immediately replace the gearbox oil that meets the specifications of the vehicle manufacturer, regardless of whether it is a manual wave or an automatic wave. This is especially important for used cars that are 5 or more years old.
