What happens if you don t change the oil for a long time

If you don't change the oil for a long time, the oil will be too dirty, which will cause great wear and tear on your engine. For a long time, sludge is generated in the engine, which affects the heat dissipation of the engine and the lubrication of the oil circuit system.

Hello, this long-term failure to change the engine oil will shorten the engine life, and this long-term failure to change the engine oil will quickly form carbon deposits inside the engine and cause oil to burn.

Hello, you said that the car does not change the oil for a long time, which causes serious wear and tear on the engine of the car.

If the car is not routinely maintained for a long time, it will lead to serious wear and tear of the engine, and the phenomenon of burning engine oil will occur in the later stage.

If you don't change the oil for a long time, the wear and tear on the engine is great, and the impurities in the oil also have a lot of wear on the engine block.

Hello, the oil of the car also has a warranty period, and if the oil is not changed for a long time, it will cause engine wear and tear, and in serious cases, the engine will be scrapped.

Do not change the oil for a long time, if the oil deteriorates. If the oil is too dirty, it will cause wear and tear on the engine.

This can lead to wear and tear on the internal parts of the engine, and even damage the engine, which is not acceptable.

Hello As you said, if you don't change the oil for a long time, the lubrication effect of the engine will not be achieved, it will cost oil, the power will decrease, and the engine will be scrapped if the oil loss is serious.

Hello, if the vehicle does not change the engine oil for a long time, there will definitely be insufficient oil stock, and there are more impurities in the engine oil, which will cause serious engine failure.

Hello, if the car does not change the oil for a long time, the oil will cause serious damage to the engine if the oil is too dirty!

Hello, this engine oil also has a shelf life, if it is not replaced for a long time, it is easy to shorten the engine life, resulting in increased fuel consumption.

If you don't change the oil for a long time, it will cause wear and tear on the entire gearbox and engine in the first place, as well as scrap, so it's best to replace it regularly.

If you don't change the oil for a long time, the wear of the engine will be exacerbated, and the wear of the rocker arm of the camshaft will be aggravated. The cooling effect on the engine will also be reduced, and there is a possibility that the cylinder may be pulled into the cylinder.

If the car is not changed for a long time, the engine of the car will be seriously worn, you can refer to it.

Hello, if you don't change the oil for a long time. The damage to the engine is quite serious. It is best to maintain it on time.

If the automobile oil is not changed for a long time, the sealing effect, lubrication effect, and cooling effect will be greatly reduced, and the impurities in the engine oil will wear out the internal parts, which will affect the service life of the engine, and will also lead to the engine being prone to failure and causing potential safety hazards.

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, which 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. It will further damage when the motive, and the harm of lack of engine oil is similar, the lack of engine oil is a direct damage, do not change it depends on whether the oil deteriorates and the performance declines, and the deterioration will be damaged after the decline, and the process is relatively long, it is slowly damaged, just like chronic poisoning, once the attack is out of control.

7. 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.

8. Once the sludge accumulation has occurred, according to the advice of the maintenance technician, the engine cleaner can be added appropriately to remove the sludge better. In addition to using additives, another approach is to shorten the oil and filter change intervals, and preferably when the oil is warm rather than completely cool, so that the old oil can be drained more thoroughly.

9. All kinds of small hazards caused by not changing the engine oil for a long time accumulate into a large load, which has a very large impact on the service life of the engine and will also cause potential safety hazards, so for the service life and driving safety of the car, please follow the reminder marked on the car maintenance manual for maintenance!

If you don't change the oil for a long time, it will aggravate the wear and tear of the engine and it will affect the performance of the engine.

Engine oil is known as the blood of the engine, and the engine oil plays the role of cleaning, sealing, heat dissipation, lubrication, buffering, and rust prevention in the engine.

Engine oil will become thinner with prolonged use, and it can also deteriorate.

When the engine is working, the oil forms an oil film on the surface of the various parts in the engine, which can reduce the friction between the various parts. If the oil becomes thinner, the oil will not be able to form a stable film, which will increase the wear and tear of the engine.

Motor oil is made up of base oils and additives, common of which are antioxidants and dispersants. The engine oil will deteriorate if it is left in the engine oil pan for a long time, so it is recommended that the engine oil should be changed regularly.

If you don't change the oil for a long time, it will also increase the sludge and carbon deposits in the engine, which is harmful to the engine.

If you have less mileage in a year, it is also advisable to change the oil once a year. Because the oil is left in the engine oil pan for a long time, it will oxidize and deteriorate.

It is recommended that riders use a fully synthetic engine oil, the base oil of this motor oil is synthetic, so the molecular size and shape are almost the same. Fully synthetic motor oils are better lubricated and last longer. The oil filter needs to be replaced every time you change the oil.

If the oil is not changed for a long time, as the oil life declines, its lubrication ability will also decline rapidly, so that the engine is not well lubricated, resulting in abnormal wear.

At the same time, the metal debris cleaned by the engine oil cannot be discharged, and it will accumulate inside the engine, and the dirt will produce a large amount of sludge.

The engine will also have increased fuel consumption, decreased power, difficulty in starting, abnormal shaking and poor operation, and in serious cases, it may also lead to the direct scrapping of the engine.

Failure to change the oil for a long time will cause very serious and irreversible damage to the engine, and the repair cost will be much higher than the daily maintenance cost. Therefore, when our vehicle reaches the specified maintenance time limit, we should change the engine oil in time, and do not lose a big one because of a small one.

Leaving the oil unchanged for a long time will exacerbate the wear and tear of the engine and will affect the performance of the engine.

Engine oil is known as the blood of the engine, and the engine oil plays the role of cleaning, sealing, heat dissipation, lubrication, buffering, and rust prevention in the engine.

Engine oil will become thinner with prolonged use, and it can also deteriorate. When the engine is working, the oil will form an oil film on the surface of each component in the engine, which can reduce the friction between the various parts, if the oil becomes thin, it will not form a stable oil film, which will aggravate the wear of the engine.

Engine oil is composed of base oil and additives, common engine oil additives are antioxidants and dispersants, and the oil will deteriorate if placed in the engine oil pan for a long time, so it is recommended that the car owner change the engine oil regularly.

Failure to change the engine oil for a long time will accelerate the wear of the engine and shorten the service life. When the engine is running, the frictional resistance increases, the mechanical loss increases, and the power output decreases.

The effects of not changing the engine oil for a long time are: 1. It leads to ineffective and deterioration of the engine oil, and increases the wear and tear damage of the parts; 2. The sealing effect is reduced, so that the oil is water-sampled and loses the sealing effect; 3. The cooling effect is reduced; 4. The precipitated magazine will corrode the internal parts; 5. The lubrication performance of the bearing and the lubrication and cooling function of the mechanical transmission parts disappear, which affects the good driving condition; 6. Damage when the motive; 7. It will produce sludge and cause engine failure. The method of changing the oil of the car is:

1. Start the vehicle engine to warm up; 2. Unscrew the oil bolt; 3. Unscrew the filter element; 4. Use new oil to apply the interface gasket of the new filter element; 5. Pour the new oil into the oil pan; 6. Check whether there is leakage in the lower part of the engine, check the oil dipstick and start the engine test.

Failure to change the oil for a long time will cause the engine to become louder, and the internal lubrication effect will not be good, which will lead to increased wear and tear on the components in the car and reduce the service life of the engine.

According to the manufacturer's maintenance manual and the oil used, to determine the time to change the oil, if it is semi-synthetic oil, it takes 6 months or 5000 kilometers to replace, if it is a synthetic oil, it needs to be replaced within 10,000 kilometers or a year. Oil precautions.

Used engine oil already contains a lot of acidic substances, oil sludge, as well as moisture and impurities due to high temperature oxidation. Not only do they cause damage to the engine, but they can also contaminate the new oil and affect performance. The oil filter should be changed at the same time as the oil change.

After a long period of use, there will be a large amount of black sludge, particulate matter and other impurities in the oil filter element, which will weaken or completely lose the filtration function, which will not play the due protective role, and will also cause the lubricating oil circuit to be blocked, and the engine will be damaged by the shaft, burning tiles, and pulling cylinders. If you often run mountain roads and dirt roads, the air filter should be replaced at the same time, and the dust adsorbed on the air filter will pollute the lubricating oil

If the oil is not changed for a long time, the lubrication effect of the engine oil will be reduced, and the internal parts of the engine cannot be lubricated when the engine is working, which will lead to the wear of the internal parts of the engine and shorten the service life of the engine.

In the case of vehicles using engine supercharging technology, when the supercharged parts start working, the engine torque is greatly increased, and the oil film covering the engine crankshaft is subjected to shear forces that are several times higher than before. The engine oil is subjected to high temperature for a long time, and the oil quality will deteriorate after a certain period of time, and the engine power will decrease if it continues to be used, and the fuel consumption will increase, and the most important thing will damage the internal parts of the engine.

1. The sealing effect is reduced.

The proper viscosity of high-quality engine oil can effectively plug 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.

2. The lubrication effect is reduced.

The lubrication system is very important to the engine, it affects the performance and service life of the engine, if the oil is not changed for a long time, the lubrication effect of the oil will be greatly reduced.

3. The cooling effect is reduced;

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

4. Increase the wear and tear of the parts.

If the car does not change the engine oil for a long time, it will lead to ineffective and deterioration of the engine oil, which will not only not play a protective role, but will increase the damage to the parts.

5. Corrosion of internal parts.

If the oil is not changed for a long time, there will be a lot of impurities in it, such as iron filings, etc., which is not only a problem of wear, but also a problem of corrosion of internal parts.

6. Further damage to the engine.

It will be further damaged when the motive, and the harm of lack of engine oil is almost the same, the lack of engine oil is a direct damage, do not change it depends on whether the oil deteriorates and the performance decreases, and the deterioration will be damaged after the decline No, and the process is relatively long, it is slowly damaged.

What is the impact of not changing the engine oil for a long time?

By long time, how long do you mean? Half a year, a year or two years?

And it depends on how you use the car, such as how many kilometers you run per day.

If it is ordinary engine oil, it is generally changed every six months, and if you insist on changing it once a year, if you use it all synthetic, if the frequency of using the car is not high, there is no problem at all for more than a year or two years, and now many people are over-maintaining the car.

Usually the 4S shop will call ** in three or four months, and he wants you to maintain it several times a year, which is really unnecessary.

So you can take out the oil dipstick, it's normal to have a little bit of black.

The oil has an attenuator, and even if the oil is not used after being opened, it will begin to oxidize after three months, and the performance will decay;

The cycle of changing oil is different for different types of engine oil, mineral oil: 5000 km or 3 months to change;

Semi-synthetic engine oil: 7500 km or change every 6 months;

Fully synthetic engine oil: 10,000 km or change once every 1 year;

CEPSA engine oil: 15,000 km or 18 months to change;

If you change the ordinary fully synthetic engine oil, it is better to replace it as soon as possible, otherwise the lubrication, cleaning and stability of the engine that have not been changed this year will weaken, and the wear and tear of the engine will be aggravated if you continue to use it, resulting in a shortened service life of the engine.
