We all know that the most important thing after buying a car is to maintain the car. The most important thing to maintain a car is to maintain the engine. It is unavoidable to change the engine oil regularly. The importance of oil is needless to say. Oil is relative to the car, just as the blood is relative to the human body. The engine is the heart of the car. The working temperature of the engine will be as high as 600 ℃. The engine oil plays the role of lubrication, cooling and cleaning the dirt generated by engine friction, so as to ensure the normal operation of the engine and prolong the service life of the engine. However, it costs a lot to change the oil early, and the engine will be damaged minutes later. So how often is it appropriate to change the oil? Mechanic: we should judge according to these aspects!
There are many factors that can affect the oil change cycle. First of all, the type of oil is a big reason. Oil is divided into mineral oil, semi synthetic oil and fully synthetic oil. Mineral oil is refined and processed from petroleum, which can meet the daily lubrication of the engine. The normal replacement cycle is 5000 km or half a year. If you drive less than 5000 km, you must change it in half a year. If you don't drive your car regularly, you need to change the oil more frequently, about once every three months. Generally speaking, for example, the Japanese car is 5000 km or about half a year to deal with and replace the oil. For example, in German cars, the oil has to be replaced after running 7500 km or half a year. Therefore, based on our different models, we change the oil at different times.
It is also necessary to judge how long to change the oil according to the type of engine. Today's household cars generally use turbocharged engine and naturally aspirated engine. Among them, the requirements of turbocharged engine oil are higher than that of naturally aspirated engine, so under normal circumstances, the oil change of turbocharged engine should be considered every 8000 km. However, if your car is a naturally aspirated engine, you can change the fully synthetic oil after driving 8000-10000 km. In fact, if we want to change the engine oil, we don't need to look at the mileage. This has nothing to do with the mileage. It depends on the state of the oil in our car. It requires the maintenance technician to test the oil condition. We can also use special test paper to check it. If blackened, it means it doesn't work, it should be replaced in time.
If you care about the vehicle in front of you and don't intend to replace it in 10 years, it is recommended that you change the normal oil at 5000 km and the synthetic oil at about 5000-7000 km. Don't think it's a waste to replace it early. If you compare the same kind of car after five years, you can see the huge difference in terms of power, fuel consumption and maintenance cost.
