Your car can run less than 10 thousand kilometers a year. Can it be maintained once a year? Any suggestions?

In reality, there are many car owners like you. If you buy a car, you have to commute 20 kilometers, 8,000 kilometers all year round. Therefore, this kind of car should pay special attention to maintenance because it drives less.

There are few opportunities for this kind of car to run at high speed, and the urban areas are generally crowded, so the biggest problem, that is, the place that needs most maintenance, is the carbon deposit on the engine. Find some good additives online and occasionally add a bottle to run. For friends who have a few miles of maintenance once a year, it is recommended to clean the throttle and intake manifold by the way.

If your car is often put on hold for half a month, I suggest you set fire once a week when you are free, which can effectively prevent the battery from dying.

As for other details to be maintained, just go as usual.

Running less than 10000 km a year, maintenance once a year may hurt the car. It is not recommended to do so.

For example, it is best to maintain a new car every 5,000 kilometers or half a year, mainly to change the oil, filter the machine, clean the air filter and so on.

This is because impurities are easy to accumulate in oil and gasoline filters, and with the increase of service time, the filtering performance will decline or even fail. If the engine oil is not filtered, it will directly enter the oil circuit circulation, which will adversely affect the performance (power decline and fuel consumption increase) and life of the engine. If the air filter is not cleaned, it is easy to accumulate dust and bacteria, which will affect human health.

In addition, the engine oil is composed of base oil and additives, and the components in the engine oil will deteriorate and fail with the driving of the vehicle. Generally, the service life of mineral engine oil is 6 months or 5000 kilometers; Synthetic engine oil is a little longer, 8 months or 8000~ 10000 km.

Of course, if it is an old car with good daily conditions and good road sections, the whole car is in a relatively stable state at this time, and the maintenance time can be appropriately extended. It is no problem to maintain it once every 7,000 ~ 8,000 kilometers.

For ordinary brands, the price of a small maintenance is usually not high. As long as you don't get cheated, the price of regular 4S stores is generally around 300~600 yuan, which I think is acceptable. Moreover, a maintenance time is generally within one hour, which is not very time-consuming.

In order to be safe and prolong the service life of the car, I think it is better to maintain it according to this requirement. However, if you mean major maintenance (major maintenance: minor maintenance+oil change machine filter, gear oil change, coolant change, hydraulic oil change, booster oil change, etc. ), can be used once every two years (major maintenance is generally 20,000 to 30,000 kilometers or once every two years).

For many family cars now, the mileage of a year is almost 10 thousand kilometers. The general purpose of the family car is nothing more than commuting. I have to go to road trip two or three times a year and return to my hometown during the New Year. Thousands of kilometers to 10 thousand kilometers a year, so if there is one more car, the number of kilometers will be even less, and there are many cases where it is less than 10 thousand kilometers a year. When scouring used cars, you can often see cars in Shanghai that are five or six years old and have a mileage of only one or two thousand kilometers. Because Shanghai is restricted, many cars actually have little time and mileage on the road. Can this kind of vehicle be maintained once a year?

Take my own as an example. My present situation is one car and two motorcycles. Motorcycle is the main tool for daily travel and going out to road trip. Cars are only used for business activities or when I need to take my family out. So my motorcycle mileage adds up to more than 10 thousand kilometers a year, while my car mileage is less than 10 thousand kilometers a year.

The maintenance cycle of a car generally depends on two indicators, one is the number of kilometers traveled and the other is the maintenance interval. Generally speaking, in the case of using semi-synthetic engine oil or mineral oil, it is 5000 kilometers or once every six months; In the case of using the whole synthetic engine oil, it should be maintained once every 65,438+00,000 kilometers or 65,438+0 years and 65,438+02 months, and the number of kilometers and time are first come first served.

The mileage has reached 10000 km for less than one year, and the oil needs to be changed; Similarly, if you drive only a few thousand kilometers a year, but you need to change the oil after one year, because the oil begins to oxidize from the moment it comes into contact with air, even if it doesn't reach the kilometer, the performance of the oil will decline after a long time, which will not protect and lubricate the engine.

So this situation is actually the same as many family cars, and it is similar to my situation. Generally speaking, I change the oil around 65438+February every year, because there are some holidays between 65438+February and I have to go back to my hometown in the New Year, so I use the car more frequently. Before that, I can change the oil into new oil, so that I can have a car.

In short, if the maintenance cycle of a car is 10000 km or one year, these two indicators will be replaced as soon as they arrive. If you drive thousands of kilometers a year, you can maintain it in time for one year.

The oil will gradually oxidize with the engine running, but it depends on the actual working conditions of the engine. If the engine often runs at high speed and high load, the oxidation speed of the oil will be accelerated, while if the engine runs in a gentle way for a long time, the oxidation speed of the oil will be slowed down. For a simple example, if the operating conditions of the same car and the same engine oil (same grade and same label) are very different, then the oxidation speed of the engine oil is completely different. Maybe the same car, the same oil runs 10 thousand kilometers a year, and the actual difference is also great. Some have nothing to do with it, but they can still be used, and some have been seriously oxidized. . .

It can be said that at present, there is no oil factory or scientific research institution in the world that can accurately calculate the mileage and cycle of oil replacement. Because there are too many individuals and the actual situation of different individuals is different, it is very difficult to choose reference objects. However, the current statement that minerals are six months, half-synthesized for nine months and fully synthesized for twelve months is only a relatively conservative estimate, which often combines factors such as vehicle environment, average mileage and fuel quality. As shown above, Jaguar's maintenance plan for some developed areas with good environment is almost 12 months, and the mileage is close to 30,000 kilometers. However, in some developing areas where the environment is not ideal, the standard has dropped sharply, becoming the early 10,000 kilometers of 12 months. . . Of course, this one-size-fits-all approach also has disadvantages, but in general, it can ensure that there is no problem with the vehicle; After all, if the environment is not ideal, such as poor air quality and high sulfide content, it will lead to premature oxidation failure of engine oil (engine oil is very afraid of sulfur, while ester high-end engine oil is very afraid of water), so at present, under the condition that the specific oil change cycle and mileage cannot be accurately calculated, relatively conservative oil change methods of half a year, nine months and twelve months are adopted; However, before long, the on-board computer will have the ability to detect the actual state of engine oil. At that time, the traditional method of fixed cycle and mileage will disappear. Therefore, the so-called how long and how many miles are used for minerals and how long and how many miles are used for total synthesis are all estimates. No one can prove that the total synthesis can be used for one year and can run 10 thousand. In other words, I've seen an example of mineral engine oil running 30 thousand a year without using anything (but I don't recommend this extreme way) .

The loss of protection and cleaning performance of engine oil is mainly caused by oxidation (another way of saying that engine oil is burned). The oxidation process of engine oil usually reacts with sulfur compounds in air and fuel oil and nitrogen oxides after combustion under the catalysis of metals to produce aldehydes, alcohols, ketones, acids and some oxygen-containing carbon deposits. The oxidation of oil is continuous, so we need to change the oil over time. From this description, we can see that the oxidation of engine oil is closely related to air, fuel quality and high temperature. If high-quality gasoline is used, it can run smoothly in a good air environment, which can slow down the oxidation process of engine oil. . . Therefore, the conclusion that mineral synthesis takes 6 months 12 months is only an estimate. We should know that the violent oxidation process of engine oil is based on high temperature environment, so the oxidation of engine oil that is not usually opened is not rapid. For example, as you said in the title, you don't drive much at ordinary times, and you can't run 10 thousand a year (I estimate it is several thousand). It can be said that your car has been parked in the basement for a long time. In this process, the oil can hardly touch the sulfur in the air, the nitrogen oxides in the air and the sulfide in the fuel. Because there is no start-up and high-temperature catalysis, the parking period should not be counted in oxidation stage. Remember, the oil gradually fails in a high temperature environment (contact with impurities), rather than being stored naturally, so your car usually uses less, and it is no problem to maintain and change the oil once a year. . . As for the suggestion, I can say that I have no scruples about it. It takes 18 months to replace mineral oil, and generally it takes at least 14 months to fully synthesize (the vehicle is insured). I'm unscrupulous, I'm not afraid of breaking down, and I've never broken down (even if it breaks down, there's room to repair it), so I've always opposed the so-called standard oil change method (all the oil collected is cheap). However, as far as you are concerned, I support your idea of changing the oil once every 0/2 months, but I suggest you still use synthetic engine oil (safety) and change it once a year. Of course, you should change the best oil. The base oil and additives of high-quality engine oil are good, so it has strong oxidation resistance at high temperature. High-quality engine oil based on GTL is extremely pure and does not contain a little sulfur, so these high-quality engine oils can easily survive for one year. For engines that are often turned on and often run at full capacity, it is really necessary to shorten the cycle and change the oil in advance (such as racing and field replacement). Cars that don't drive often don't need to change oil, and it is enough to synthesize them once a year; Why is total synthesis expensive? More expensive is not only the more advanced base oil, but also the formula. . .

How often does the car need maintenance? Many car owners worry that long intervals are not good for their cars, and too frequent intervals will waste money. So how should they judge when their cars should be maintained?

The most important thing in car maintenance is to replace the oil filter, and the rest will be decided according to the usage and mileage of the vehicle. Therefore, how often to do maintenance depends on how often the vehicle oil needs to be changed. As for the oil change cycle, I believe everyone is familiar with it. Mineral oil for half a year or 5000 kilometers, synthetic engine oil for half a year or 7500 kilometers, synthetic engine oil 1 year or 1 000 kilometers. The mileage and time here are or, that is to say, as long as one of the two conditions is met, maintenance should be done, rather than changing the oil after both conditions are met.

The maintenance time can be shorter than the recommended period, but not longer than the recommended period. Because the main function of engine oil is to protect the engine and cool, clean, seal and lubricate the engine, all functions are very important. After the replacement cycle, the oil will be oxidized and dirty, and the effect will gradually weaken, and the protection of the engine is not as good as that in the validity period. So the car travels less than 1000 km a year. As long as it is used in synthetic engine oil, it should be possible. Try to choose a better engine oil, not only considering the antifreeze factor in winter, but also considering the working viscosity at high temperature.

As for vehicle maintenance, there is no problem as long as it is regularly maintained according to the replacement cycle of the oil used. In addition, in addition to replacing the oil filter, there are other items that need to be replaced regularly, such as air filters and air conditioning filter elements. It is recommended to replace it every year. Different types of antifreeze and spark plugs have different replacement cycles. You can check the instructions or ask the service consultant of the 4S store, and you need to replace them after the expiration. Others are tires, brake pads and other safety-related wear parts, which should also be replaced according to the wear condition.

Why don't so many private car owners know this problem? Still don't understand the harm of not changing oil for a long time?

It is ok to change the oil once a car travels 10 thousand kilometers. The only difference is whether the oil grade you use is enough. If you use all synthetic engine oil, it is ok to ensure the quality of the oil, but it is definitely not possible to maintain it once a year.

The service life of mineral oil is 5,000 kilometers, and that of semi-synthetic engine oil is 7,500 kilometers. Everyone is still more concerned about the number of kilometers. The only problem is time. Nowadays, many private cars may not run 10 thousand kilometers a year, so not many people are willing to replace them, thinking that my engine is made of good oil and it is unnecessary.

This is not right. If the engine is cooled at high temperature for a long time, the oil will deteriorate and oxidize, which is not good for the engine, because the oil not only has the function of lubrication, but also has the function of cleaning, which is why all cars require a certain time to change the oil. Long-term operation of engine oil will bring impurities and greasy things on the engine surface to the bottom of the oil, so that each change is equivalent to changing blood for the engine, with the aim of purifying the engine.

Give a simple fault case. Some cars can run 300 thousand kilometers without overhauling the engine. Even if you open the engine cover, you can see that the inside of the cylinder cover comes from Huang Liang, Huang Liang. However, some cars have run 654.38+0.5 million kilometers and there are traces of burning oil, and you can see that there is a lot of greasy inside when you take apart the engine. This problem is caused by engine oil, so don't underestimate it.

Personally, I suggest that car owners, even those who use synthetic engine oil, should change their cars twice a year, and understand that people should keep cars, not drive them.

As for car maintenance, in fact, the car factory has instructions. For example, he will prompt you that you can choose 5000 kilometers or half a year for the first insurance, whichever comes first.

But often in the process of actual use, driving does not reach the maintenance mileage, and the maintenance time is up. Just like the landlord, it is less than 10 thousand kilometers a year. Is it necessary to maintain it twice? You know, one more maintenance will cost six or seven hundred dollars. It seems a bit uneconomical.

Some people think that in the case of the landlord, it is enough to use high-grade engine oil and maintain it once a year. It seems reasonable.

But according to my experience, it should be maintained twice, at least three times every two years.

The reason is simple: less travel means low utilization rate and less wear and tear of the car. But car maintenance is not just about changing the oil, but also the maintenance of other parts. If it is not maintained for a long time, in addition to the aging of the oil, other related parts of the car will also age, thus participating in different degrees of failure.

Even if there is no problem, there will be concerns in my heart: if the period is not extended, will there be problems?

Therefore, it is still necessary to maintain it according to regulations. Don't be afraid to spend hundreds of dollars to protect your car and give yourself peace of mind and safety.

Cars are wear and tear products, especially the new car you just bought. Be sure to run in well, and post-maintenance is also very important. Good maintenance will save you a lot of worry in the later use, and of course it will indirectly save you a lot of maintenance costs.

Many people don't use cars very much, just to come in handy when needed, so they don't run much. A year later, they may not even reach 10000 km. Normal vehicles have to travel at least 20,000-30,000 kilometers a year. As we all know, many car maintenance is calculated in kilometers. Generally, the first insurance is 5000 kilometers or three months, and better cars will be available.

We usually have two indicators for car maintenance, one is the number of kilometers and the other is the interval. In this case, you should refer to the second indicator.

Generally, when we buy a car, we will get a maintenance manual, which will indicate the maintenance cycle. Most vehicles need to be maintained at least once every six months after the first insurance. This is mainly to check whether the detailed indicators such as oil, battery and coolant are normal.

Therefore, the best advice is that vehicles should not drive often in time or park for a long time. It is ok to drive out for a walk, and the maintenance should not be too long, so that the later use can be guaranteed.

According to the fact that you can run less than 10 thousand kilometers a year, you don't need long-term engine oil. For example, Mobil ep belongs to long-acting engine oil, so you can run 12300 km without problem. However, the oil added to the engine has a shelf life. Even if your mileage is not up, change it when the time comes. There is no need to choose long-term oil. My suggestion is to choose Castrol to protect synthetic engine oil as a whole, protect the engine from cold start and reduce engine wear. Or choose shell extraordinary Heineken, which has good cleanliness and can keep the engine in a state for a long time.

Maintenance can be carried out in strict accordance with the instructions. The following are personal suggestions. Don't spray if you don't like it

It is recommended to change the common oil every 5000 kilometers or half a year. Those who run at high speed and drive violently can be replaced by synthetic engine oil. This kind of oil can fully protect the engine at high speed and under bad conditions. It is recommended to replace it every 8000 kilometers or 10 month for city trips. Those who drive too little can change it every 1 year or 10000 km.
