The engine is known as the "heart" of the car, is the most important part of the car, the performance of the engine directly affects the overall performance of the car. If you want the engine of the car to be used for a long time, you have to maintain it carefully, and you must pay attention to the details of the car when driving usually, so as not to cause damage to the engine and affect the service life of the car because of improper operation.
In the course of daily driving, there are several behaviors that seem harmless, but actually hurt the car very much. Novice drivers often make mistakes, and old drivers often make mistakes. Today, I will tell you about these 4 wrong behaviors, if you also have such bad habits, you must change them as soon as possible.
First, add inferior gasoline
Now the price of gasoline is rising very fast, and the No. 92 gasoline in many cities has risen to more than 7 yuan, and it costs 40 or 50 yuan more to add a tank of oil than before. Originally there was a lot of pressure to raise a car, and now that the oil price has risen, the pressure on their own car is even greater, and some car owners will choose some small gas stations on the side of the road in order to save fuel expenses.
Some small gas stations are actually "small workshops", they add a lot of impurities to the gasoline, these substances can not be fully burned in the engine, will aggravate the engine carbon deposits. If this inferior gasoline is added frequently, it will increase the frequency of engine cylinder pulling, and over time, it may also lead to engine scrapping.
Second, high-end low speed
High-end low speed is a lot of novice drivers often appear in the wrong operation, in the process of driving encounters the front car congestion, the driver will urgently step on the brakes, reduce their speed, so as not to collide with each other. But many novice drivers only know how to reduce the speed of the car, but forget to change gears, and have been maintaining a high-end low-speed driving state.
Hanging high-grade slow cars, the gasoline in the engine can not be fully burned, and carbon deposits will form inside the engine. Over time, there will be problems such as difficulty in starting the vehicle, increased fuel consumption, and decreased engine power. Driving in this way is also easy to wear out the engine and clutch, causing damage to the clutch. The damage caused by high speed and low gear to the engine is irreversible, and can only be replaced and cannot be repaired.
Third, often increase the number of motor oil
The most important item in car maintenance is to change the oil, many people think that the higher the oil label, the better for the car, so when you go to maintain the car, you will always let the staff add the highest number of oil to yourself.
Engine oil is a lubricant, its main role is to relieve friction and high temperature, rust, sealing. The oil is not the higher the label, the better, we need to choose according to different weather conditions and the performance of the engine. If it is only a 100,000 yuan family car, there is no need to use the most expensive motor oil.
Fourth, idle hot car for a long time
Many people have heard that in winter, the car should be heated in the same place first, and then drive after the water temperature rises. Generally, a hot car in situ can be used for one minute, but some people will stay in place for 5 minutes or even 10 minutes when the car is hot. This is very unnecessary, and the in-situ heat car will accelerate the formation of carbon deposits for a long time, and it will also cause some damage to the engine.
Car owners think that these operations are the protection of the car, but they do not know that such operations actually cause great damage to the engine invisibly. These injuries are irreversible for the engine, and it is too late to make up for it in the future, so you can only replace the engine again. If you also have these habits, be sure to correct them in time.
