Now many novice drivers are only able to drive, either over maintenance, or do not know when to do maintenance for their cars. After driving for tens of thousands of kilometers, an icon of a small wrench appears while driving, indicating that it's time for us to go for maintenance. Sometimes, even shortly after maintenance, the icon of a small wrench suddenly appears. At this time, many drivers are worried. Is there something wrong with my car? I also asked for maintenance. It's only a short time since the maintenance. Should I go? If I don't care, will there be any problem when it's overdue?

The most important thing for us to do is to change the filter and the oil. In general, our car needs to change mineral oil every 5000 km or every half a year. We can change all synthetic oil every 10000 km. But overseas, their fully synthetic oil can run 20000 kilometers or even 30000 miles. Why can oil from other countries run tens of thousands of kilometers? But our engine oil can only run 10000 kilometers?

Actually, the 4S store adjusted it for your car. A lot of people don't know that they can set their own settings in the travel computer on the car. Every time we go to the 4S store, the little brother of the 4S store will help us to set up maintenance reminders in the central control of the car. For example, the mileage will be set to 5000 km or 10000 km, or the time can be set to 3 months, 6 months or 1 year. So if the time limit is exceeded, the maintenance sign will pop up.

For example, I have been driving my own car for so many years. Basically, I have to drive mineral oil for about 7000 to 8000 km before I go for maintenance, and I have to drive all synthetic oil for 15000 km before I go. There has never been any problem. Therefore, we should not worry too much about this. It doesn't matter if we don't have a long time to jump out of the repair sign. It's OK to drive for maintenance when you have time. After maintenance, the prompt appears again, which is likely that the settings have been forgotten.

However, the maintenance time should not exceed too long. If the engine is not maintained for a long time, the most likely problem is the engine. The engine oil will bring out some slag and dirty things from the metal friction in the engine. If the engine oil is very dirty, the engine oil fails again and does not maintain for a long time, then the engine will have a big problem over time. If we don't maintain the vehicle for a long time, it will also lead to carbon deposition in the parts. Carbon deposition often occurs in the engine of our car.

Carbon deposition not only has the characteristics of oil absorption, but also allows incomplete combustion of gasoline to be converted into carbon deposition. These carbon deposits will lead to the decrease of the power of our engine, the increase of our daily fuel consumption, the difficulty of cold start of vehicles, the excessive emissions of vehicles, the shortening of the engine life of our vehicles, and the shortening of the vehicle life. So there's no problem with the short time of overdue maintenance, but it won't work after a long time.
