【Car owner's car knowledge】As a car owner, you must often receive text messages and phone calls from 4S shops and repair shops, and it's time for seasonal maintenance! Come and experience free testing and more. Worrying about the accident of the vehicle, or coveting the free small price to test, once the result is tested, there are a lot of problems, and the hidden dangers are endless!
When buying a car, the 4S shop said that the maintenance of the car is only five or six hundred yuan each time. After buying a car, there is basically no maintenance less than 1,000 yuan each time! Several times it is still nearly 2,000 yuan! In fact, it is not the 4S shop deceiving marketing, but in the actual maintenance process, after inspection, there are many items that need to be added, and the car owner It has to be done to ensure safety, so it costs a lot more.
So when repairing, among the lists provided by the merchants, which ones should be replaced? Which ones should not be replaced? The easiest way is to operate according to the "Maintenance Manual", but if there are some situations outside the manual, how should the owner judge? ?
"Over-maintenance" repairs 70% of the most damaged cars
For the sake of corporate profits, 4S stores make early or excessive maintenance, so that consumers at least double their money, which is also a great waste.
How to avoid over-maintenance? Read the manual more, and the book that needs to be replaced regularly has instructions. Shortened maintenance mileage and frequent replacement of parts are not only unnecessary, but also damage the car. Before the maintenance, the owner can ask the specific items and costs of the maintenance. If the maintenance is not necessary, the owner has the right to refuse.
1. Excessive cleaning of paint surface premature aging
Just like if people take too many baths, it may lead to dry skin, aging and even reduce the resistance to external bacteria, too many “baths” for the car will also lead to premature aging of the car paint, and even after a period of time. Causes rust and corrosion of the car floor, the bottom of the door and other parts.
All car beauty shops are unavoidable, of course, it is even more serious in some street car wash points: the mud and sand carried by the reused car wash rags will scratch the car paint, and these small scratches are illuminated by the street lights at night. The most obvious ones are called sun spots. When the sun spots are serious, the brightness of the car paint will decrease. Maybe car owners will say, if you want to brighten it, just wax it. This is another source of aging vehicle paint: too frequent waxing.
Whether it is polishing wax or glazing wax, there is a certain degree of grinding on the paint surface. If waxing is too frequent, the paint surface will become thinner and thinner, which will affect the color or gloss of the paint surface.
suggestion:Prepare a feather duster like a full-time driver, and use it to remove a little ash, which can greatly reduce the number of car washes. Of course, be careful with the duster to avoid scratching the paint. In the case of normal dust fall, washing the car once every 10 days is enough. As for waxing, if you choose a longer-lasting waterproof wax, you can do it once a quarter or half a year.
2. Vehicle fuel and various lubricants are too much.
Careful selection, and often buy some car "supplements" to supplement the car. However, this high-priced supplement may be a drug! A car is a very delicate product, and it has corresponding technical specifications for fuel, lubricating oil, brake fluid and coolant. If it is necessary to add or replace, the user should refer to the relevant regulations in the user manual, add and replace it with quality and quantity, and must not use oil casually, otherwise it will cause harm to the vehicle.
Many fuel and oil additives that claim to enhance power and reduce fuel consumption not only fail to achieve the functions bragged in advertisements, but also aggravate engine wear and seriously damage the three-way catalytic device, resulting in unqualified vehicle exhaust. Therefore, as long as the car is used and maintained normally, these so-called supplements are not actually needed. If there is such a need, the regular products designated or approved by the car manufacturer must also be used.
suggestion:If you have used oil additives, please change the oil immediately, and the fuel additives should also use the products certified by the manufacturer. In fact, most of the fuel sold by domestic gas stations has already added detergents, and you also pay an extra 4 cents per liter for this, so there is no need to add it.
What are the necessary maintenance?
Practice has proved that in my country, it is better to perform primary maintenance once every 5,000 kilometers, and perform secondary maintenance once every 20,000 to 30,000 kilometers. Don't be frightened when you hear people in the 4S store say that there are safety problems if you don't maintain them.
As long as the vehicle has undergone secondary maintenance in a regular repair shop, if there is an accident due to the vehicle, the repair shop will be held responsible.
