Although it is convenient for us to buy a car in our daily travel, we should also bear the corresponding responsibilities. Automobile is a relatively large mechanical product, and it is inevitable that there will be various failures in normal use, so it is very necessary for us to maintain the automobile regularly. But you know what? Some maintenance projects are actually dispensable, and even after they are completed, they are not only useless, but also have negative effects. However, the staff will never tell you these negative effects when doing maintenance. It's a waste of money to show you four maintenance services that must be rejected.
1 air conditioner maintenance.
It's hot summer now, and the first thing we have to do when we get into the car is to turn on the air conditioner. However, if the air conditioner is turned on for a long time, it will inevitably produce some bacteria, which will affect the health of the owner. At this time, a staff member will tell the owner. It is popular to maintain air conditioners to keep them clean for a long time. Many car owners have some conation after listening to it and spent a lot of money cleaning the air conditioning filter. But this step can actually be done by yourself. Cleaning the air conditioner only needs to buy a little detergent, so there is no need to spend so much money.
The second is tire maintenance.
In the maintenance project, in addition to testing the tire pressure, the car will also be waxed. When we ask for tire maintenance, the staff will clean the tires and then wax them. After the maintenance, the tires will be as good as new. It looks good, but it's not necessary. Even if the tires are well maintained, they need to be replaced regularly. Cleaning tires does not extend the service life of tires.
The third is to clean the car seat.
Nowadays, many car seats are made of leather, so some car owners will ask for cleaning the seats in the car when they are in maintenance. The price of this maintenance project is really not low at all. The more expensive the model, the higher the price, at least several thousand yuan. However, the cleaning agents used in auto repair shops are actually bought online, and the price is several hundred yuan. A bottle of cleaning agent can clean dozens of cars, so why should we buy cleaning agents?
The fourth is oil pollution cleaning.
Some cars have been driving for a long time, and the owners will feel that the power is getting weaker and weaker. Therefore, they will choose to clean the oil circuit during maintenance, which is simply to clean up the carbon deposit inside the engine. Cleaning up carbon deposits is a good thing, but frequent cleaning may cause big problems. Generally speaking, it is enough for ordinary cars to clean the oil circuit once every four years, and it is not necessary to do it often. If the oil circuit is cleaned frequently, it is likely to cause damage to the engine.
