What happens if you don t maintain your car and only change the oil after you buy it?

If you don't change the oil and don't maintain it, the car will soon have problems, and the service life of the car will be greatly reduced.

If you only change the oil, nothing else, you can drive it in 2 to 3 years, if you are not a careful owner, you will not find the resistance of the car, such as increased fuel consumption, weak power, sometimes one or two alarm lights may pop up.

The maintenance of the car is mainly to change the oil, and the oil is changed during maintenance, and the rest are small parts.

Just change the oil, change it when the mileage is reached, the oil is like the blood of the engine. Regular replacement will reduce wear and extend engine life. Within 20,000 kilometers, there is basically no change.

It's the same as a new car. If it is 4 to 60,000 kilometers, the air filter will be too dirty, which will affect the air intake, and the fuel filter will not be replaced, and there will be too many impurities, resulting in poor oil quality of the intake engine. If the air conditioning road is not changed, the air quality in the cab will be very poor.

Ignition will be affected if the spark plug is not replaced. So at this time, the engine begins to shake, the car starts to start, the fuel consumption is high, and so on.

If you don't have a car to maintain, it's easy to get into an accident, unless you plan to drive it for two years.

The maintenance of the car is very important for the performance of the car. For automobiles, maintenance generally refers to the replacement of oil and air filters, gasoline filters and oil filters, and others generally include air conditioning grids, gasoline grids, brake pads, brake fluid, transmission fluid, differential oil, spark plugs, antifreeze, and belts, tires, batteries, etc. that are easily damaged after a period of time. If you only change the oil and never maintain the vehicle, you may not be able to commute to work, but the safety is not guaranteed.

If you don't maintain it properly, many problems will ensue in the future. ‍‍

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. Perhaps many car owners think that maintenance is simply a change of oil.

As long as you change the oil on time, you won't have a problem, which is an unsound idea. So be sure to do a good job of maintenance.

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. However, if you use the car like this, unless you only want to drive it for a few years, you don't want it, because of improper maintenance, many problems open Pandora's box and flock to it.

If a car from the buy back only change the oil never maintained, basically equivalent to a small maintenance, according to the family car 10,000 kilometers per year of the course to calculate, five years only 60,000 kilometers, in 60,000 kilometers before the maintenance of the general will not be a problem. The life of ordinary spark plugs is 20,000 kilometers, and it can still be used after more than 20,000 kilometers, but it is recommended not to exceed 40,000 kilometers, otherwise the ignition efficiency will decrease, resulting in a decrease in engine power; The life of a single platinum spark plug is 5-80,000 kilometers, which needs to be replaced regularly, and the performance of a single platinum spark plug decreases as normal anode, cathodic ablation, ignition gap change, etc.; The life of iridium spark plugs is 50,000 kilometers, and when the performance is reduced, it is manifested as cathodic ablation, resulting in the change of ignition gap and the decrease in stability, so it is recommended to replace them regularly; Brake fluid is as important as brake pads, brake fluid is different from other fluids, it has strong water absorption, once wet, it will cause the brakes to be soft and the braking distance to increase. ‍‍

There are no other problems with a car, just changing the oil is enough.

I am the owner of the 2014 Changan Yidong car, bought the car in April 2014, and it has been more than three years now, driving more than 140,000 kilometers, and returning to my hometown three times, Sichuan. I went to Shanghai three times, all of which were more than 1,600 kilometers away, I walked in the morning, and arrived at 12 o'clock in the evening, and now there is no problem with the car. Light maintenance is not good, occasionally you have to pay attention to other parts, you still have to understand a little bit of your own driving, the province is saved, you can get your own get, of course, if you are a big money, of course, it doesn't matter, there is another point is that whether it is in the ** change things, these things must be bought a little better, tires, brake pads, engine oil, famous brands, don't be cheap.

The condition of the vehicle is discounted, and the value of the second-hand car shrinks: compared with the timely maintenance of the car, the car that is not maintained in time will be discounted in the working conditions, and the common ones are high engine noise, the gearbox shift is not smooth, the chassis is noisy, and the car is not powerful enough, and the vehicle health index of the car is directly related to the value of the second-hand car. If you are usually kind to him, you can sell it for a good price when it is time to sell, and conversely, 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. 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.

If the maintenance only replaces the oil filter, it does not mean that there is no problem with the engine, according to the current electronic control technology of the car, then before, first of all, at 1-20,000 kilometers, your engine does not clean the throttle and begins to shake, and because your air filter element does not care for a long time, the filtration is even worse, the throttle is very dirty, and the intake manifold and the engine are carbon deposits, which will lead to the phenomenon of cold car difficult to start, high fuel consumption, and weak acceleration. ‍

Now the car pays attention to 3 points and 7 points of maintenance. That is to say, the current car technology is relatively mature, and it will not be overhauled at every turn as before. Nowadays, the improvement of automobiles is mainly in the addition of electronic products and the continuous replacement, and the basic mechanical principles have not changed much.

Just change the oil, change it when the mileage is reached, the oil is like the blood of the engine. Regular replacement will reduce wear and extend engine life. 100,000 kilometers, at this time, I feel that there should be very few at this time, haha, 100,000 kilometers should have been discovered a long time ago, if you can drive it all the time, no problem.

But the exhaust gas is not up to standard. The car is also boring. Loud noise.

There is no big problem with normal small maintenance, but it is recommended to wash it. After all, washing and decarbonizing will save fuel, and the car will also be worry-free. It is easy, too.

All manufacturers have strict recommended time and mileage for the maintenance of their own brand cars. It must also be admitted that in order to evade their responsibilities and shorten the maintenance cycle, the manufacturer will objectively earn indirect profits for its authorized SSSS stores to increase revenue and production. Therefore, objectively, manufacturers have the benefit of reducing the repair cycle in order to benefit from it.

So we can't trust the manufacturer's recommended maintenance interval, and we can't fully trust it. The choice of most smart people is to appropriately extend the maintenance mileage and time recommended by the manufacturer on the premise that the car does not react abnormally.

Car maintenance is divided into major maintenance and minor maintenance, and minor maintenance usually refers to oil change and three filters. If a car only changes the oil and never maintains it, it is basically equivalent to minor maintenance. According to the annual course of 10,000 kilometers of family cars, it is only 60,000 kilometers in 5 years, and there is generally no problem before 60,000 kilometers of maintenance.

If you don't change the oil filter for a long time, it will clog. When the oil filter is clogged, the circulation drops dramatically and the bypass valve in the middle of the filter is switched on. At this point, the function of the filter element will be lost.

Some impurities or metal powders produced between engine parts will enter the circulation with the oil, and these metal powders will spread to all lubricating surfaces like sand particles, causing a lot of friction and destroying the finish of the parts. However, some fine sludge will also adhere to the inner wall of the oil pump and the oil circuit, resulting in a decrease in pump pressure and a slower oil circulation, which will also affect the heat dissipation of the engine and cause the engine temperature to rise.

Now the quality of the car is really good. Unless the design is flawed, proper maintenance is hardly a big problem. The daily maintenance of the car is very important, which directly affects the life of the car and also has an important impact on safety.

Some friends will over-maintain, and each early shouting maintenance will be mentioned, so there is no harm in spending money on multiple cars, but there is no need, just follow the instructions for maintenance.

The consequences of not maintaining the car only changing the oil: there will be more and more problems in the car engine, the oil only plays the role of lubrication and wear reduction, cooling and cooling, if the oil is not maintained for a long time, 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.

The effects of not changing the oil when the maintenance time is up are as follows: the sealing effect, lubrication effect and cooling effect of the oil are reduced. If the maintenance time is up, the oil will be water-sampled and lose its sealing effect; The effect of lubrication will be reduced, resulting in dry friction or semi-dry friction between the cylinder and the piston, accelerating the wear of parts, and the starting resistance will be greatly increased, resulting in difficulty in starting.

The hazards of not changing the engine oil for a long time:

1. If the car does not change the engine oil for a long time, it will lead to ineffective and deterioration of the engine oil, and the engine oil will not only fail to lubricate and protect, but will increase the damage to the parts.

2. The sealing effect is reduced, and the appropriate viscosity of high-quality engine oil can effectively block the gap between the cylinder block and the piston to prevent gas leakage. If the oil is not changed for a long time, the oil will be watery and lose its sealing effect.

3. The cooling effect is reduced, the heat absorption and thermal conductivity of the oil are much higher than that of water, and if the oil deteriorates seriously, the heat dissipation function will be greatly reduced.

4. If the oil is not changed for a long time, a lot of impurities will be precipitated, such as iron filings, large particles of dust, etc., which is not only a problem of wear, but also a problem of corrosion of internal parts.

5. Once the oil deteriorates and the performance decreases, the lubrication performance of the bearing and the lubrication and cooling function of the mechanical transmission parts will disappear, which will affect the good driving condition.

6. If the car does not change the engine oil for a long time or uses inferior engine oil, it will lead to the generation of oil sludge. When there is too much sludge in the engine, it is difficult for the oil pump to maintain enough oil pressure, which can lead to engine failure, which is the heart of the car, and once it stops working, it will increase the cost of repair.

<><It is not possible to only change the oil for car maintenance, and the old driver tells you that these places are also very important

We all know that today's society is developing rapidly, and many people's living standards have been greatly improved, so there are more and more people buying cars, but many people who take people home to buy cars only to find that cars are really a troublesome thing, and monthly maintenance requires a lot of money. However, many car owners are not particularly familiar with the car, and each maintenance is only a simple change of some oil. In fact, many parts of the car that cannot be seen are equally important, and they also need strict maintenance, and car maintenance is not good for only changing the oil, and the old driver tells you that these places are also very important.

The first

It is the ignition device - spark plug, as long as anyone who has driven a motor vehicle knows, the spark plug is an important part of starting the vehicle. Many people may not know what this is, the spark plug is actually the ignition system to direct the current into the cylinder and then produce a spark so that the car ignition is successful, so the spark plug is a very important component, without him, there may be no way for the car to ignite and start. The general spark plug needs to be checked for replacement during the period of 3-100,000 kilometers, as long as it is within the service life.

The second

It is the brake oil, the brake fluid is born with the characteristics of water absorption, the brake oil is actually used as an auxiliary when the hydraulic brake brake, so after a long time, there will be a lot of water in the brake oil, which will have a great impact on the brakes of the car, which is very unsafe, so we should check and replace it when maintaining. Generally, the two-year cycle of automobile brake fluid, but it is not certain, and some vehicles have a very short requirement for brake fluid replacement time when they leave the factory, such as medium and large cars, performance cars and other models that need more mandatory power.

The last one is the "cage cover", the car knowledge is a white driver, do not understand what is the cage cover, its main role is to drive the car at high speed, if the cage cover is damaged, then the lubricating oil of the cage will be thrown out in high-speed driving, resulting in dry grinding of the cage, if the lubricating oil in the cage flows out, the car may be abnormal noise or frustration; In severe cases, it may cause a traffic accident. Therefore, regular replacement or lubricating oil will reduce the abnormal noise of the car or the frustration of the liquid, which cannot be ignored.

<> "Car maintenance only changes the oil? If these things are not changed, it is a blind toss!

Does everyone know? In today's society, cars are becoming more and more common. For the majority of car owners, it is also very convenient for us to have a car when we travel.

But after all, it is a consumable, and after a period of use, it also needs to be maintained, otherwise it will cause very large losses.

Let's start with a brief introduction! Brake cylinders. This part can be said to be often overlooked, because of the location, the things it comes into contact with the most are dirt and water, which makes the place always dirty.

However, because of these things, this part is prone to rust. If this part is rusty, then the wheels of the car will always be locked to the silver, the braking ability will be reduced, and the fuel consumption of the car will increase significantly.

That's right! Spark plug, an ignition device, is an extremely important part in the ignition system of gasoline engine, if the spark plug does not pay attention to maintenance, the carbon deposit on it is too much, or too much precipitated material is accumulated, the spark plug gap increases, and the ignition energy of the disturbance tong is insufficient, resulting in difficulty in starting the car.

Once the spark plug fails, the ignition system cannot work normally, resulting in insufficient combustion of the mixture, and some harmful substances are discharged without sufficient combustion, which also causes an increase in fuel consumption. Spark plugs are not without life, generally speaking, the life span is between 40,000 km and 90,000 km, and it must be checked and maintained at any time.

In fact, antifreeze, the car will inevitably have a temperature rise when driving at high speeds. And with antifreeze, it can play a very slow and good cooling effect. In addition, it also has the effect of anti-corrosion and cleaning, and has great room for vehicle protection.

Of course, the special brake oil, today's cars all use hydraulic brakes, and this kind of braking needs brake fluid to transmit. However, brake fluid has a very bad characteristic, that is, it is easy to absorb water, and after driving for a long time, we will find that the water in the brake fluid will increase.

This will lead to a decrease in braking performance, especially when braking suddenly, the braking level will also be significantly reduced, so for your own safety, you should also check and replace it regularly.

All in all, we must replace the above things in time, but don't say what the 4S shop says we will change, that excessive maintenance will only waste our money, every time before going to the maintenance of the car manual, what should be replaced is written clearly, according to the manual maintenance of other items are not done, 4S shop will never pit you.
