No matter what kind of car, maintenance is a must, but according to the age and car habits, the frequency of maintenance and the project are not the same. If you go to the 4S shop for maintenance, the staff will often recommend some dispensable items, which are necessary on the surface, but in fact, there is no difference between doing it and not doing it, which will only make you waste money in vain. Therefore, in this issue, we will talk about several more pit maintenance projects, there is no need to do it in the 4S store, hoping to help the owners.
The first is the so-called air conditioning maintenance.
We all know that car air conditioning is very important, whether it is a new car or an old car, before entering the summer, we must pay attention to cleaning or replacing the air conditioning filter, otherwise the dust inside will damage the respiratory system of the human body. However, if you go to the store to maintain the air conditioner, there are many routines, such as the staff will suggest that you do a sterilization of the air conditioner in the car, and claim that it is the activity price, the price is not high.
But if you really want to calculate, removing a single fungus is enough for us to buy more than ten bottles of fungicides, and do maintenance in the store, encounter irresponsible masters to spray casually, may not do their own clean. In fact, the air conditioning sterilization operation is very simple, buy a bottle of fungicide, open the internal circulation of the air conditioner, and the air conditioner will be clean in a short time.
The second pit is engine maintenance.
On the surface, the engine does need maintenance, but there is no need for excessive maintenance, usually only need to change the oil, the machine filter basically does not care. However, in the store maintenance, the staff will often fool you to buy some value-added packages, the project is often some cleaning, basically useless, for example, will sell you engine protector, that is, oil additives.
In fact, the oil additive is dispensable, if it is really needed, it is completely unnecessary to add at the time of maintenance, buy your own addition, operate in the 4S shop, and may also charge additional fees, which is not worth the loss.
The third is oil circuit cleaning.
I believe that many car owners have such an experience, when they go to the 4S shop for maintenance, the store will engage in a lot of activities. Especially cleaning projects, such as inlet decarbonization, oil circuit cleaning, hydrogen and oxygen decarbonization, etc., and will be discounted, a project is not expensive.
However, these cleaning projects are completely unnecessary, and if you hesitate, you can easily be persuaded by the staff. In fact, it is not as good as running at high speeds to do these so-called cleaning and maintenance, or cleaning the throttle regularly, which is completely enough.
The fourth pit maintenance is brake maintenance.
Needless to say, the brakes are very important, so 4S shops often work hard here, and when maintaining, they will recommend a bunch of brake maintenance packages. Generally speaking, the vast majority of family cars can change the brake pads after running about 50,000 kilometers, and at this time, the staff will push the boat along the water and launch some brake maintenance packages.
At this time, it should be noted that if you agree to this service, it is equivalent to entering the pit, and when you pay, you will find that there are some cleaning agents or brake ointment on the bill, and the cost is not low. Therefore, if you really want to maintain the brakes, you must be clear about the specific charges of these items and whether there are additional costs, if you do not pay attention, you will suffer more losses at that time.
The fifth is tire maintenance.
It is completely unnecessary to do maintenance for tires, I believe many people are also hearing about it for the first time, but the staff will often tell you bitterly how good it is after tire maintenance.
But when you finish doing it, you must be surprised, in fact, there is no much maintenance, that is, the tires are brushed clean and then waxed, and these operations can be completed when washing the car or by yourself. Buy some tire wax or the like on the Internet, the effect is not much worse, and it is very cheap, there is no need to spend money.
The last pit maintenance item is the fuel additive.
When refueling, the staff of the gas station often sell fuel additives, the most common is the fuel treasure, many people feel that it is really useful or embarrassed to refuse. Especially for some turbocharged models, it is also recommended to use fuel additives when going to the store for maintenance, the reason is that the oil is too poor, and the engine is easy to accumulate carbon.
Of course, fuel additives do have an effect on some cars with a long service life, such as driving for more than 5 years. But there is no need to add in the store, buy a few bottles from the Internet, and add them before refueling, which is not only cheaper but also more secure in quality. Well, this issue of some maintenance projects that are easy to be pitted will first talk about this, and see you in the next issue.
