Everyone knows that the most important thing after buying a car is to raise the car. The most cautious thing to raise the car is to raise the engine. It is inevitable to change the oil regularly. Needless to say, the importance of engine oil is relative to cars, just as blood is relative to the human body. The engine is the heart of a car. When the temperature of the engine is as high as 600℃, the engine oil plays the role of lubricating, cooling and cleaning the stolen goods produced by engine friction, ensuring the normal operation of the engine and prolonging its life. But changing the oil early is very expensive, and it will destroy the engine a few minutes later, so how often is it appropriate to change the oil? Auto mechanic: We should judge according to these aspects!

There are many factors that will affect the oil change interval. First of all, the type of oil is a big reason. Engine oil is divided into mineral oil, semi-synthetic oil and fully synthetic oil. Mineral oil is refined from petroleum, which can meet the daily lubrication of engines. The normal replacement cycle is 5000 kilometers or half a year. If you drive less than 5000 kilometers, you must change it every six months. If your car doesn't go out often, change the oil more frequently, about once every three months. Generally speaking, like Japanese cars, the oil will be changed after 5000 kilometers or half a year. Change the oil every 7,500 kilometers or half a year like a German car. Therefore, based on different models, the timing of oil change is different.

It is also necessary to judge how often to change the oil according to the engine type. Nowadays, turbocharged engines and naturally aspirated engines are widely used in family cars. Turbocharged engines require more oil than naturally aspirated engines, so in general, you should consider changing the oil every 8000 kilometers. But if your car is a naturally aspirated engine, you can replace the whole synthetic engine oil when driving 8000- 1000 km. In fact, if you want to change the oil, you don't need to look at the mileage, which has little to do with mileage. It depends on the state of the oil in your car. This requires the maintenance master to test the engine oil, and you can also check it yourself with special test paper. If it's black, it won't work well. It should be replaced in time.

If you care about the vehicle in front of you and don't plan to replace it within ten years, I suggest you change it to ordinary engine oil for 5,000 kilometers and synthetic engine oil for 5,000-7,000 kilometers. Don't think it's a waste to change it too early. Five years later, comparing similar cars, you will find great differences in power, fuel consumption and maintenance costs.
