Hello everyone, I'm Xiao Li. The car was bought by saving money by themselves, and everyone wanted it to be healthy and healthy for a few more years. Therefore, as soon as a new car is bought, people who understand the car or do not understand the car will take special care of the new car, and pay attention to the maintenance and maintenance. But the same car is in the hands of people who know cars and people who don't know cars, and the gap is obvious after 5 years.
People who don't know how to buy a car will immediately put on the film given by the 4S store and spray the chassis armor paint sent by the 4S store. But the 4S shop is not charitable, if they really send you a good film, a good chassis armor paint, it will be a blood loss for them. In order to facilitate the transaction, most of the films sent to you are the kind of stalls, commonly known as dyed films, the kind that cost a few dollars a meter on the Internet. Chassis armor paint is also that kind of bargain, in fact, it does not play a protective role. After 5 years, or even 5 years, the film faded and even bulged, and the chassis paint almost fell off.
If the budget is not enough when people who know cars just buy a car, they will also use this film first, but they will soon spend some money and replace it with a first-class film, and the chassis armor paint will also be sprayed better. **The film has a better thermal insulation effect and is not prone to fading. On the road, I saw that the windows of many cars have become transparent, and most of them are people who buy cars for the first time, because they don't understand the car and don't understand the doorway, so they use the film sent by the 4S store.
People who understand the car are generally free of charge and return to the 4S shop to do maintenance, after the first and second insurance, they are basically outside to do maintenance, and people with strong hands-on ability even maintain the vehicle themselves. People who don't know how to do cars generally don't dare to go to the outside repair shop to do maintenance, they often think that the 4S shop is more reliable, and it is better to do maintenance in the 4S shop, and it can be foolproof. But if you maintain the car in the 4S shop, after driving it for 5 years, you will find that the old driver's car may be more fuel-efficient than you, the power is better than yours, and the maintenance cost for 5 years is much lower than yours.
Most of the maintenance in the 4S shop is a waste of money, spending the same amount of money, but using cheap spare parts, the labor cost is too pitiful. For example, I used to maintain it once in a 4S shop, and it was just a simple change of oil filter, which cost more than 500, and the oil was only used for more than 200. I secretly asked the maintenance master who was working, and I said what kind of quality engine oil this engine oil was, and the maintenance master told me: this kind of engine oil is actually semi-synthetic, and it is best to use fully synthetic engine oil for a turbocharged engine like yours. I maintain and change the fully synthetic engine oil outside, not to mention how much the car repair shop makes me, at least for the same money, I can use the best real fully synthetic engine oil. Change the battery 4S shop for 1400, outside 800 to get it, so people who know cars generally do not go to the 4S shop for maintenance. 
People who don't know how to drive don't dare to go to private gas stations to refuel, and their cars are filled with 92 gasoline, so they definitely don't dare to add 95 gasoline for fear of burning out the car. I go to the car wash regularly for fear of getting dirty and damaging the paint, but I never dare to wash the engine compartment every time I wash the car. And as long as the person who knows the car is a 92 car, then the oil of 92 or 95 can be used casually, and reliable private gas stations can also add it. If the car is dirty, then wash it, don't do any routine of washing the car regularly, and rinse it if you find the engine compartment dirty. 
Finally, there are two very common habits of people who don't know how to drive, that is, the seat cover, and there will be the problem of overheating the car. There is nothing to talk about about the seat cover, it is a personal preference, and the old driver generally does not set it. Excessive heating of the car will lead to an increase in engine carbon deposits, and there is a clear difference between cars that have been used for more than 5 kilometers for more than 5 years. The engine compartment of the old driver's car has always been relatively clean, and even if it is filled with oil from private gas stations, there will be no problem of high fuel consumption and weak power. However, novice cars are used carefully, and there will still be various problems such as weak power and high fuel consumption.
