Will changing the engine oil of a car once every 3 years damage the car?

Hello The general manufacturer's recommendation for engine oil is. Replace every three months at 5000 km. After expiration, the quality of the oil will deteriorate and the lubricating properties will deteriorate.

This leads to increased wear and tear on the engine and increased noise. For your car, it is only once every three years to replace it, and there is already a lot of greasy oil in the lubricating oil, so it is recommended to clean the oil duct before changing the oil. Hope it helps.

Generally, even if the lubricating oil is not used, the physical indicators will be reduced in three years, and the contact air will be oxidized, and the quality of the oil will deteriorate seriously in three years.

The life of the car oil is generally about two years, and the oil will produce gum for a long time, which is easy to hang inside the machine, which has an impact on engine lubrication.

It is definitely not possible to change the engine oil every 3 years, even if it is a fully synthetic engine oil, the service life is one year. I run more than 20,000 miles a year, and the GT engine oil I use is exactly two times, and I used to change it almost three times with ordinary fully synthetic engine oil, and the power is almost bad. And now a lot of fully synthetic engine oil said that it can run 18,000 kilometers are a bit empty, and the power of the individual with GT is almost more than 10,000 kilometers, and the power will be a little worse, according to the standard of 12,000 kilometers.

So if you change it every 3 years or 20,000 kilometers, the engine will definitely have problems.

Change the oil once every three years that has a very big impact, the validity period of the engine oil is generally about one year, whether you drive or not, you must change the engine oil for about a year, change the engine oil once every three years, the oil has lost its lubricating effect, if the vehicle has been driving, it will damage the engine.

I hope for the above suggestions, thank you.

Of course, there will be damage, like this case, the general is that our maintenance is as long as it is a change of season, it should be maintained, for example, you are changing the oil in winter, then it should be replaced in the summer, otherwise the oil will also have a shelf life, it will also lose its performance, in this case, the damage to the engine is relatively large, and you will overhaul it in advance anyway.

The engine oil of the car also has a shelf life, 79 changed once every three years, which is obviously more than this time. Generally, we recommend 5000 kilometers or replace nine every six months. If it is a long time, only a long period of high temperature combined with air will produce oxidation, or too many internal impurities, causing this scenery to wear and tear.

The damage to the engine is very great if the car oil is changed once every three years, the engine oil has a shelf life, and the oil is easy to deteriorate after a long time, and the effect on lubrication and heat dissipation will be much worse, which will lead to the aggravation of the wear and tear of the engine.

Car oil should be changed every three years. At this time, the engine oil has deteriorated, emulsified, lost lubrication, noise reduction, and cooling, which will lead to serious engine wear and tear, and will produce oil burning. Therefore, the car oil must be changed on time.

If in the Northeast, there is also a summer and winter division. Replacing the lubricating oil with qualified quality is the premise and basis for ensuring the service life of the engine.

First of all, the oil of the car is changed once every three years, and it has no effect on the car, mainly because the engine needs to change the oil once as long as it runs more than 10,000 kilometers, because the oil has been tried and the interest rate has passed, so as long as it has not run enough for 10,000 kilometers in three years, it is not necessary to change.

The engine oil is turned off once every 3 years, which will have an impact on the service life of the vehicle's engine, because the engine oil also has a shelf life, and the viscosity of the engine oil will decrease after the expiration date, which will lead to insufficient engine lubrication.

No matter what the mileage you drive, changing the oil once every three years will definitely hurt the car, because the chicken fillet is best changed twice a year, there is a difference between winter and summer, if it is not returned for more than a year, it will be very harmful to the car, not to mention that it is not changed for three years, and the damage to the car will be very great.

If the engine of the car does not change the oil for a long time, it will definitely have an impact on the engine, especially in terms of wear, etc., which will increase the degree of engine wear. 10,000 km is recommended for fully synthetic oil, or at least once a year, and 5,000 km for semi-synthetic oil, or once every six months.

Under normal circumstances, the engine oil should be changed once a year, even if you don't open it, after opening it, the oil will come into contact with air, oxidize, and the lubrication performance will drop sharply, causing unnecessary wear and tear to the engine.

Generally, the maintenance cycle of the car is one year or 10,000 kilometers based on the principle of first arrival, so if you do not change the oil for three years, the damage to the engine is particularly large. It is easy to cause engine failure.

Definitely not, at most once a year, long-term not to change the engine is not good, accelerate engine wear, sludge carbon deposition increases, easy to cause oil burning, when the overhaul of the engine costs more, the gain outweighs the loss.

Changing engine oil in three years is not a no. When the case is 5000 7000km change the oil. Or a year. Failure to change the engine oil for a long time can lead to accelerated engine wear.

The oil of the car engine has its life, and the general fully synthetic oil is required to be changed once a year, and your car has not changed the oil for three years, and the lubricity of the oil will be discounted and it is a big discount, so it is best to change the oil once a year at the latest.

It is recommended to replace it at least once a year, because many of them are mineral synthetic oils, and there will be a shelf life after the high temperature of the engine, after which the oil composition will decline or change and affect the engine performance.

I didn't open it after changing it, and I put it for 3 years and it was fine, but I need to change it again before I open it. If it is open for 3 years. Let's scrap it.

Well, probably not, because he's not. The length of time, hey, a matter of a few years, is how many kilometers the lover has run, and how many kilometers have been an. Is it the kilometers to change the oil? So, well, if you say that time, there is no right or wrong kilometer to calculate.

3 years is too long, damage is for sure.

Car oil has a certain shelf life. It is divided into six months and one year. There are 10,000 kilometers of kilometers in 5,000 kilometers.

It took only 3 years to drive 100 kilometers, so what damage can there be?

It also depends on what model, there is no absolute.

There is no damage to the car, because the oil change is not related to the time, but only the distance, so there is no damage to the engine.

Of course, there is damage to the engine, because oxidation will slowly occur after not changing the oil for a year, and the impact on the engine is still relatively large, so it is still necessary to change the oil in time.

There will be some damage to the engine, mainly because if you do not change the oil for a long time, it is very likely to solidify, and in this case, the engine will slowly be damaged.

It will be damaging to the engine because there are some impurities in the oil that can wear out the engine.

Of course, there will be damage to the engine, so in this case, you should go to the 4S shop and let a professional person check it for you.

No, even if it is a fully synthetic engine oil, it can't be changed every 2 years. 2 years to change the oil will deteriorate, even if the mileage is less, but the dismantling of the engine for a long time, a year is already the limit, change the oil working hours 30-50, the filter element is only more than 20 pieces, 4 liters of fully synthetic engine oil is only 400 pieces, all add up to only 500 pieces, don't lose a big deal because of the small.

Strictly speaking, fully synthetic engine oil is 100% high-quality oil produced after careful blending of PAO (polya-olefin) or synthetic esters, with good stability and durability, so the oil change interval of general synthetic engine oil can be extended to 7500-10000 kilometers.

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.

It is recommended that the fully synthetic engine oil should be changed for 10,000 kilometers, or once in a year.

The replacement interval for fully synthetic oils is one year or 10,000 kilometers. Due to the good performance and strong oxidation resistance of fully synthetic oils, the use cycle may be longer. Semi-synthetic oil has a replacement cycle of 8 months or 7,500 km, while mineral oil has only half a year or 5,000 km of service life.

This cycle needs to take into account both time and kilometers, and if one of the two meets the deadline, it needs to be replaced, and it cannot wait until it arrives at the same time.

1.Oil is often added, but not replaced, and not changing can only make up for the lack of oil, but can not fully compensate for the performance loss of lubricating oil. The performance of engine oil gradually decreases due to pollution, oxidation and other reasons during use, so there is a certain consumption and the quantity is reduced.

2.The role of oil additives is very great, high-quality engine oil is a finished product with a variety of engine protection functions, the formula already contains a variety of additives, and the oil pays the most attention to the balance of the formula to ensure that the performance of the full play. Adding other additives by yourself not only does not bring additional protection to the vehicle, but also easily reacts to the chemicals in the oil, thus reducing the overall performance of the oil.

3.Swap the oil after it turns black. Engine oil has a cleaning effect.

It can clean and dissolve carbon deposits and oxides inside the engine. It can be seen that the black substance in the engine oil is the carbon deposit and oxidation product inside the engine. So even if it is a brighter oil, it will turn black for a while when it is added to the engine.

This is the oil that plays a cleaning role, so blackening is completely normal. When it gets dark, you have to change it.

The main functions of automotive oil are lubrication, cleaning, and cooling. The decay of the oil is over a period of time. "Normal" generally starts oxidizing after about 3 months of exposure to air (6 months for "semi-synthetic" and 9 months for "fully synthetic").

The function is reduced, and the effect of engine lubrication, cleaning, and cooling cannot be achieved, causing damage to auto parts. So it's unscientific to say that car oil needs to be changed once a year, have you learned?

Need. Because the car's oil is changed twice a year to better protect the engine, I think it is needed.

It needs to be replaced twice a year, because it will maintain the car without damaging the engine and protect the other parts of the car.

Yes, the oil of the car needs to be changed twice a year, because it is beneficial to the service life of the car and is better for the car.
