Generally, there will be some problems when the car is used for a period of time, but as long as the quality of the car is fine, even if there are some problems, it is better to solve them. In the past, the domestic car-making technology was relatively backward, so a common problem of many domestic car couples is that there are too many minor problems, and now the technology has been improved, but some cheap cars still have these minor problems. Here's a common problem of insufficient engine power, the reasons for insufficient engine power and the reasons for insufficient engine power.

1. Problems with the engine are generally related to the oil circuit of the car. When the oil circuit fails, the engine can't work normally, so it is easy to cause the gasoline to fail to reach the designated place, and there is no way to provide power for the engine. Generally, this kind of situation will make the power of the engine smaller and smaller, making the feeling more and more obvious. Therefore, this is usually caused by the blockage of the fuel injector or the blockage of the gasoline filter. Just go to the repair shop to check and replace it.

2. The fuel quality is not good. Many people think that the car costs a lot of oil, so it is better to add some ordinary oil to the car, which saves money and the car can be used normally. But after a long time, we will know that this will lead to carbon deposition in the engine, and the money needed for this treatment is far more than the money you saved, and it will damage the engine. Generally, there are regulations on how much oil to add to a car. You can choose high-grade but never low-grade.
