The four most expensive car maintenance projects! Don't be fooled by novices: spend money to destroy cars!

For all car owners, car maintenance is a very, very expensive and energy-consuming thing. In order to save trouble, many people will drive their cars to the 4S shop to make a maintenance package, and the 4S shop will also launch many maintenance projects for profit, but many maintenance projects are expensive, with average results, and even bad for the car, especially the four most expensive car maintenance projects! Beginners should not be fooled again: "I spent money and ruined the car"!

First, air conditioning cleaning.

4S stores often use the slogan of respiratory health to recommend car owners to do air conditioning cleaning. If the air conditioner is not cleaned, it will indeed accumulate dust and bacteria, which will easily make passengers sick, and if the air conditioner is not cleaned for a long time, it will inevitably have serious odor. So many car owners are very happy. However, the way to clean the air conditioner in 4S shop is to spray cleaning agent on the air inlet of the air conditioner, and then open the external circulation to let the air circulate, and it is over. A little detergent costs two or three hundred yuan, which is very expensive.

Second, tire maintenance.

Tire maintenance in 4S stores is just cleaning and waxing to make them look like new ones. However, tires, as automobile consumables, are not the type that can prolong the durability and service life by washing and waxing, so there is no need for maintenance at all. On the contrary, it may affect the friction of tires, leading to accidents and car damage during driving.

Third, the deep maintenance of the engine.

In fact, deep maintenance is to clean up the dust of the engine, then add the cleaning agent to the engine through the intake pipe, and then run at idle speed for a period of time, so that the cleaning agent can clean the carbon deposits and blockages in the engine. The effect is average, and hundreds are collected at a time. Many car owners are easily fooled when they see the name of this maintenance project and think of the importance of the engine.

Fourth, oil cleaning.

This is originally an important maintenance project, and the price is relatively high. Many 4S stores seize this point and constantly fool customers to do oil cleaning and maintenance. If you refuse, I will tell you immediately that not cleaning the oil circuit will make the fuel consumption of the car higher and higher, reduce the power of the car, make it difficult to idle the car, and even shorten the life of the engine. Many car owners listened to the truth and did it anyway. However, the oil circuit is not so easily blocked. Generally, you can do it once every 30,000 to 40,000 kilometers. Unless you use inferior gasoline every day, the three-way catalyst on the exhaust pipe will be damaged if the oil circuit is cleaned frequently.

Therefore, when you go to the 4S shop again, you must pay attention to the four major car maintenance projects that burn money. If you can't do it well or even spend money to destroy the car, especially for three or four maintenance projects, it will cost hundreds of dollars just to clean up the carbon deposit. In fact, the owner can do it at home, and it is cheaper and simpler.

Fuel treasure can achieve the same effect. A fuel treasure is only a dozen dollars. You can add a refueling treasure to the tank when you refuel. The cleaning ingredients contained in it can follow the flow of gasoline, clean the carbon deposits in the oil circuit and the engine, and let the engine get rid of the burden.

That is, the fuel consumption of the car is obviously reduced, and the engine is lubricated, the service life is prolonged, and the carbon deposit is prevented from damaging the engine. It's better to do it yourself. It's better to go to the 4S shop and be fooled into doing some burning money or even destroying the car.
