What happens when a car comes back from buying it and only changing the oil and never maintaining it

The correct answer is that when the tread is worn to the warning line, it must be replaced, the vast majority of people run 50,000 kilometers without a problem, assuming that the tread surface grinds to the warning line, in fact, it can still be driven, but the highway drainage has decreased a lot, and the high speed should not exceed 80 on rainy days! In reality, we also see that some cars are already slick tires and are still in use!

I can tell you clearly. A car only changes the oil, and nothing else matters, and it can indeed be used normally for a few years or tens of thousands of kilometers without any major problems.

Let's not discuss whether the car electrical appliances, chassis parts are damaged, etc., which are not directly related to routine maintenance, but simply discuss what impact the maintenance that should not be done will affect the car. Other maintenance items include spark plugs, air grids, air conditioning grids, gasoline grids, brake pads, brake fluid, transmission fluid, differential fluid, and antifreeze. After a few years, there are belts, tires, batteries, etc. that are easy to be damaged.

I am an auto mechanic. When a car comes back from the purchase of a car only to change the oil and do no other maintenance, this problem is very acute and very realistic. As a mechanic, I have also met a lot of similar car owners.

I thought that as long as I ensured that there was a gasoline car in the fuel tank, I could go, just a few days ago, I met a car, ran 30,000 kilometers, turned on the engine fault light, came to the store to check, and finally found that the owner had not changed the oil since the car was lifted, and the sludge in the engine was particularly thick.

It's useless not to change the oil filter.

All manufacturers have strict recommendations for the maintenance of their own brand cars and mileage, and we must also admit that in order to avoid their own responsibilities and shorten the maintenance cycle, manufacturers will objectively increase the income output for their own authorized SSSS stores to make indirect profits. Compared with the timely maintenance of the car, the car that is not maintained in time will be discounted in the working conditions, the common engine noise, the gearbox shift is not smooth, the chassis is noisy, the car is not enough power, the vehicle health index of the car is directly related to the value of the second-hand car.

Don't look too delicate about the car! The quality of the car is actually getting better and better, and the durability of various wearing parts is also improving, including the current oil quality compared with a few years ago, and there is also a detailed improvement! If a car only changes the oil (the oil and the filter are at the same time) if you usually commute to work, drive for 4 or 5 years, an average of 10,000 kilometers a year, it may be nothing, according to the value retention rate of second-hand cars, the value retention rate within five years is the highest, and you can change the car at that time!

There won't be any problems in a short period of time, and if you don't drive diligently, you won't have a problem in the new year. No matter how long it takes, the car will have to go to the repair shop often.

If you are usually kind to him, you can sell it for a good price when you need to sell it, on the contrary, someone else's car may sell for a car of the same year at a much higher price than yours. Moreover, if the car is not in good condition, it will be more difficult to shoot. Everything Nima is fair, care is mutual, usually be good to the car, timely maintenance, in addition to giving you a better driving experience, when leaving, it will also give you better money feedback. ‍‍

Air filter and air conditioning filter, according to the provisions of the general two years to change, one is to prevent dust into the engine, one is to filter the dust in the car, two years up, you can take out a blow to blow a duster to continue to use, the air may affect the engine air intake, there may also be a small amount of dust in, but it will really affect the life of the engine, it is estimated that it is 3 months If it is calculated according to 15 years of life, the air conditioning filter may affect the cleanliness of the air quality in the car!

Changing the engine oil is also considered maintenance, but if you only change the engine oil after driving for a long time, it may have a greater impact on the engine life of the car.

If a car is only changed from the purchase of the oil and never maintained, many problems will come in the later stage. For example, in the engine, the oil only plays the function of lubrication, but also needs accurate air intake, strong ignition, and precise oil supply. The air intake is the air grid, which has not been changed, and every time the oil is changed and blown clean, the problem is not big, and it can not be used until it is rotten.

The ignition is a spark plug, which is generally changed for 50,000 kilometers, and if the gasoline is good enough, it is not a big problem to use 100,000 kilometers. In terms of oil supply, the fuel injector is generally cleaned and washed, and there will be no problems. Gasoline grid If the gasoline is good enough, 100,000 kilometers is fine.

But the engine is precisely coordinated, and several factors are in poor working condition, and the problem comes. Cooperate with each other and influence each other.

The engine will accumulate a lot of impurities, and it is easy to accumulate carbon elements, which will lead to the noise of the engine and the shorter life.

There will be more and more problems in the automobile engine, the oil only plays the role of lubrication and wear reduction, cooling and cooling, if only the oil is changed for a long time and not maintained, it will affect the normal operation of the engine, resulting in serious carbon deposition in the engine, weak acceleration, and will also lead to an increase in fuel consumption.

If you just change the oil, there is basically no problem, but the basic components also need to be maintained regularly.

It can cause a lot of damage to the car and can also cause a lot of damage, which may affect the engine of the car. You should maintain it regularly in your life to make the life of the car longer.

There is harm. Because in addition to changing the oil, the car also has to change a lot of things regularly, so it is harmful to the car.

There will be some damage to the car, because it is likely to affect the engine and cause the performance of the car to deteriorate.
