What is a major and minor car maintenance?

1. The basic meaning is different:

Minor maintenance refers to the routine maintenance items done at the time or mileage specified by the manufacturer to ensure the performance of the vehicle after the car has traveled a certain distance. This mainly includes changing the oil and the oil filter.

Major maintenance refers to the routine maintenance of oil and oil filters, air filters, and gasoline filters at the time or mileage specified by the manufacturer.

2. The interval is different

Intervals for minor maintenance: The duration of minor maintenance depends on the oil used and the effective time or mileage of the oil filter.

3. The supplies are different

Supplies during minor maintenance:

1. Engine oil. 2. Oil filter element machine.

Supplies in the big maintenance:

1. Engine oil. 2. Oil filter element machine.

3. Air filter.

4. Gasoline filter.

The first warranty of this car is 5000 kilometers, and the small maintenance is to replace the oil filter, which is relatively simple, and the car does more small maintenance. Generally, the quality of the engine oil used for maintenance in the 4S shop is not very good, I buy accessories for maintenance, and use imported G T magic red engine oil, which is the base oil of the four types of PAO, and the quality is much higher than the general three types of full synthesis, the anti-recession ability is good, the fluidity and protection are very good, the maintenance mileage can be mentioned to 15,000 kilometers, the anti-wear protection ability is very good, the power output of the engine is more sufficient, the protection effect of the engine is very good, and the driving experience is very good.

The main thing is to replace the oil filter, air filter, gasoline filter, air conditioning filter, and do some basic checks, I have done it twice before, the cost performance is not high, there is no need to follow the maintenance manual. I am now doing maintenance in the outside auto repair shop, ** lower than before, the engine oil can also be replaced with G T magic red engine oil four types of PAO base oil, there are liquid molybdenum additives, anti-wear protection ability is very good, as long as you do these routine inspections when looking at the point, let the master operate the standard point.

Hello! The minor maintenance of the car generally includes the replacement of the engine oil and the replacement of the machine filter, while the major maintenance includes the replacement of the air filter and the replacement of the air conditioning filter. There are also couples of the engine group and so on.

Major maintenance is long overdue, and it is also necessary to protect the engine with better oil. The engine of my Volkswagen car is quite good, and I have basically not spent any money on repairs in the past few years. The engine oil is GT Magic Red, I enjoy driving too much after changing, the car is quiet and there is no noise, the accelerator is not sticky, and the power output is timely.

In addition, GT belongs to the four types of PAO engine oil, which has high durability and can run 15,000 kilometers to change the power, saving a lot of energy.

The main thing is to change the oil, three filters and routine inspections. If the noise is loud, you can check the engine intake and ignition, if there is no problem, you can change the silent oil, I have always used GT Magic Red engine oil, with the addition of liquid molybdenum, the anti-wear protection ability is very good, the silence is obvious, and the driving experience is much better than the previous engine oil.

Running 50,000 kilometers can do major car maintenance. The major maintenance steps are similar, and auto repair shops can also do it. Engine noise is mainly related to the quality of the oil changed.

Noise cancellation can change the car to a higher-end PAO oil. The major maintenance of my car is also done by the auto repair shop, but the engine oil is GT Magic Red that I brought myself, which is relatively niche but not fake, and the effect is better than ordinary fully synthetic engine oil. Usually driving can not hear any engine noise, now the maintenance is 15,000 kilometers to change, the power decline period is 10,000 kilometers.

The car is a powerful assistant in our daily life, and now almost every household has a car, since there is a car, it is inseparable from the later maintenance. But there are some car owners who really don't know anything about the car, and they don't know when to do maintenance, or when to do which maintenance items. General car maintenance is divided into "major maintenance" and "minor maintenance".

The major maintenance and small maintenance of the car correspond: the car has a long maintenance interval, long mileage and many items, and the small maintenance interval is short, the mileage is short and the project is few.

For the vast majority of private cars, major maintenance is usually done once every three years or 60,000 kilometers, and it is best to do all the items on the maintenance manual, such as: inspection and replacement of five oils and three waters, replacement of generators and fan belts, replacement of spark plugs, etc., which is a very good opportunity for us to understand the condition of the car; Small maintenance is usually done once every six months or about 7500 kilometers, and there are few projects, basically changing the oil filter. In addition, if you usually use a lot of cars, you can also maintain them in advance.

Minor maintenanceSmall maintenance generally refers to the routine maintenance items done at the time or mileage specified by the manufacturer to ensure the performance of the vehicle after the car has traveled a certain distance.

This mainly includes changing the oil and the oil filter. Motor oil is made up of base oils and additives, and the components in the oil deteriorate and fail as the vehicle is driven. Oil filters can also deteriorate or even fail over time.

If these two maintenance products are not replaced in time, it will have a negative impact on engine performance.

In addition to replacing the oil filter, the air filter and gasoline filter should be replaced.

air cleaners; The function of the air cleaner is to filter out dust and particles in the air and ensure that sufficient and clean air enters the cylinder. If left unfiltered, the dust in it accelerates the wear of the piston pack and cylinder. Larger particles enter between the piston and the cylinder, which can also cause a serious "cylinder pulling" phenomenon.

gasoline filters; Gasoline filters provide clean fuel to the engine and filter out moisture and impurities from gasoline. Keeping the engine performing at its best while also providing the ultimate in engine protection.

In addition, after driving a long distance, the car also needs to replace key components such as brake fluid, antifreeze, transmission oil, and timing belt according to the situation.

The daily maintenance of the car is mainly to replace the oil filter to effectively protect the normal operation of the engine. According to the quality of the engine oil, the synthetic engine oil can be 7000-10000 km or 5 months, and the ordinary engine oil can be changed once every 5000-7000 km or every three months.

The fuel filter is replaced once every 20,000 kilometers, and the air filter is replaced once every 10,000 kilometers. The air conditioner filter is replaced once every 1 year.

Brake fluid and booster oil are replaced once every 40,000 yuan. There is also transmission fluid, antifreeze, etc.

Major maintenance is generally carried out once in 50,000 or 60,000 kilometers, 10,000 kilometers will replace the air filter, and 5,000 kilometers of small maintenance is mainly to change the oil and filter. If you want to reduce the number of minor maintenance, you need to change to a good enough oil. The GT Magic Red I use now is the PAO engine oil, and there is no problem in changing it for 15,000 at a time, so I don't have to go there so often, and I can directly change the air filter together, which saves a lot of work.

Major maintenance is mainly to replace the oil and oil filter, air filter, gasoline filter, some brake pads, spark plugs, etc., generally a small maintenance is enough. For new cars, it is necessary to change the oil to give the engine the best protection from the beginning. My home GT Magic Red is an imported motor oil with liquid molybdenum in the formula, which can reduce engine wear and power.

Vehicle routine maintenance 3-5w kilometers need to do a small maintenance according to the use of oil to decide, different oil maintenance cycles are different, like my car uses GT oil, the use of four types of PAO base oil, small maintenance is 15,000 kilometers to replace once, than the semi-synthetic oil I used before 3 times.

Now the automobile market is in full swing, and almost every household has a car. But many car owners don't know much about car maintenance. Below, we will introduce some car maintenance knowledge from the perspective of distinguishing between major and minor maintenance.

Minor maintenance generally refers to the daily maintenance items carried out to ensure the performance of the vehicle due to the short driving distance of the vehicle, mainly including changing the oil and oil filter and conducting daily inspections. Car engines need to be lubricated, and oil lubricates, cleans, seals, and cools. However, as the car drives, the base oil and additives in the engine oil will deteriorate and fail, so in order to protect the engine, the oil needs to be changed regularly.

Major maintenance is based on minor maintenance. In addition to the oil and oil filter, the replacement care product also added an air gas filter and a gasoline filter. These two cartridges filter dust from air and impurities from gasoline, respectively.

The proper functioning of the engine is based on the rational use of various skin care products. If the third oil filter is not replaced in time after it reaches the end of its useful life, it will have a negative impact on engine performance. In addition, after a long drive, key components such as brake fluid, antifreeze, transmission fluid, and timing belts need to be replaced.

At the same time, in the cycle, it is recommended to change the oil every 5000-7500 km (the maximum time should not exceed half a year), and at the same time change the oil filter element; Replace the air filter element every two oil change cycles. Replace the gasoline filter every three oil change cycles; Replace the air filter element in spring and autumn every year; The engine system is cleaned every 30,000 kilometers and the spark plugs are replaced every 30,000 kilometers; Replace the vehicle auxiliary oil every 2-3 years or 5-60,000 kilometers.

It's really easy to buy a car, but it's hard to keep a car. Both major and minor maintenance should be done regularly and on time. It's always good to love a car a lot.

<> "The difference between minor and major car maintenance.

The contents of the minor maintenance:

Minor maintenance generally refers to the routine maintenance items done at the time or mileage specified by the manufacturer to ensure the performance of the vehicle after the car has traveled a certain distance. This mainly includes changing the oil and oil filter.

Intervals for small maintenance:

The duration of minor maintenance depends on the oil used and the effective time or mileage of the oil filter. The validity period of mineral engine oil, semi-synthetic engine oil and fully synthetic engine oil of different brand grades is also different, which can be recommended by the manufacturer. The oil filter element is generally divided into two types: conventional and long-lasting, and the conventional oil filter is replaced with the oil, and the long-lasting oil filter lasts longer.

Supplies during minor maintenance:

1.Engine oil is the lubricating oil that runs the engine. It can lubricate, clean, cool, seal, reduce wear and other functions of the engine. It is of great significance to reduce the wear and tear of engine parts and extend the service life.

2.An oil filter is a component that filters engine oil. Engine oil contains a certain amount of gum, impurities, moisture and additives; In the process of engine work, the metal shavings generated by the friction of various parts, impurities in the inhaled air, oil oxides, etc., are all the objects of oil filter filtration.

If the oil is not filtered and goes directly into the oil circuit, it will have a detrimental effect on the performance and life of the engine.

The contents of the big care:

For each major maintenance, all the items included in the minor maintenance are generally performed. The major maintenance items will be distinguished by different details according to the different vehicle designs of different manufacturers. But broadly speaking, it will also have a vague commonality.

Major maintenance consists of changing the engine oil and routine maintenance of the oil filter, air filter, gasoline filter, etc.

Intervals for major maintenance:

Major maintenance is based on the existence of minor maintenance, and generally these two types of maintenance are carried out alternately. The interval varies depending on the brand and model of the car.

Supplies in the big maintenance:

1.Air filter.

The engine sucks in a lot of air during operation, and if the air is not filtered, the dust in it will accelerate the wear of the piston group and cylinders. Larger particles enter between the piston and the cylinder, which can also cause a serious "cylinder pulling" phenomenon. The function of the air filter is to filter out the dust and particles in the dust-containing air and ensure that sufficient and clean air enters the cylinder.

2.Gasoline filter.

The function of the gasoline filter is to provide clean fuel to the engine and filter out the moisture and impurities of the gasoline. This optimizes engine performance and provides the best possible protection for the engine.

First, small maintenance. When your car has been running for a while, you feel that the various functions are still running normally, and there are no bad situations. You can do some small maintenance appropriately, which can achieve the effect of protecting the function of the car, avoid serious failures, and spend more money on future maintenance.

At the same time, always keep the car in peak condition, improve the performance of the car, and adopt the correct minor maintenance method, that is, maintenance when driving 5,000 to 10,000 kilometers.

Second, moderate maintenance. When the car has traveled more than 20,000 kilometers, it needs to be serviced. The main items of this maintenance included four oil filters and throttle valves.

Because the car is driving on the road for a long time and the current environmental pollution is serious, it is easy to cause dust to enter, which will reduce the service life of the car and the power of the engine. Therefore, when carrying out these maintenance projects, the car can be cleaned, and the driver can also reduce the breeding of bacteria in a relatively clean environment and avoid the occurrence of diseases.

The third is major maintenance. This maintenance method includes medium and small maintenance. Secondly, some other items have been added, such as the inspection and replacement of four oils and three fluids and wearing parts.

If you want to use this maintenance method, you can also judge by the number of kilometers you exercise. The optimal distance is between 60,000 and 80,000 km. But when doing major maintenance, you must be careful, because many merchants will randomly replace some parts for you.

In fact, when carrying out these maintenances, especially for some family cars, there are many parts that do not need to be replaced, only a simple inspection is required, such as clutch plates, gasoline filters, etc., their service life is very long.
