How to use lubricant additives? How to apply lubricant and where to apply

Lubricating oil additives are the most useless, it is simply an IQ tax, the lubricating oil itself is composed of base oil and additives, the chemical composition is calculated respectively, and you add lubricating oil additives yourself, but it will destroy the performance of the oil itself. Do you think that the power meat, you can change a PAO base oil of full synthesis, I directly change the German GT engine oil, PAO content of 50%, as well as liquid molybdenum additives, all of which are imported quality, so that the power start is very easy, I step on the accelerator to have a power reaction and push back feeling.

Tips for using engine oil additives New cars within 10,000 kilometers do not need to be used, and the engine is in a state of youth and in good health. It is necessary to add unless there is a condition of engine quality, noise, power, etc. 2. For engines with a mileage of more than 50,000 kilometers, the use of engine oil additives can play a protective role, prevent wear and reduce carbon deposits and sludge.

3. The engine with a mileage of more than 100,000 kilometers will wear and tear greatly, the engine noise will also increase, and the power will begin to decrease, the vibration will increase, etc., and it is necessary to repair the slight wear and enhance the sealing, and it is necessary to use oil additives. 4. Many vehicles burn engine oil at 8-100,000 kilometers, and oil additives can alleviate or improve slight engine oil, and can also avoid the occurrence of cylinder pulling due to serious oil loss. 5. For car lovers who pay more attention to driving experience, the use of engine oil additives is a good choice for playing with the car, which is quieter, more powerful, and brings endless fun to a good experience, and can avoid the damage to the engine at high speed.

The lubricant is used as follows: unscrew the cap, squeeze some (bean-like stool is enough) in your hand, blend the lubricant in your hand and apply it to the area that needs to be lubricated. Lubricating fluid is a lubricating medium used to reduce the frictional resistance of the friction pair and slow down its wear.

The lubricating fluid can also play a role in cooling, cleaning and preventing contamination of the friction pair, and in order to improve the lubricating performance, suitable additives can be added to some Runyedenan slip agents. When selecting lubricating fluids, it is generally necessary to consider many factors such as the movement of the friction pair, the material, the surface roughness, the working environment and working conditions, and the performance of the lubricant. Lubricant is a substance used to lubricate, cool and seal the friction part of machinery, which is divided into oily liquid lubricating oil, greasy semi-solid grease and tung solid lubricant.

The lubricant can play a role in cooling, cleaning and preventing pollution, and most of them are distributed to the parts that need to be lubricated through the lubrication system, which has the advantages of good cooling performance, good permeability and low environmental pollution.

Engine lubricant additives refer to a mixture of several single agents that are mixed in a certain proportion and blending process to meet the requirements of a certain quality level. The concept is to add one or several compounds to the lubricant in order to obtain some new properties of the lubricant or to improve some existing properties of the lubricant.

By the way, a certain treasure is suspected of being worth a bottle for dozens of dollars, and the 4S store is basically 200 yuan smaller, not counting working hours.

The role of engine lubricant additives:

1.The gum, carbon deposits and other insoluble substances produced after oxidation can be suspended in the oil to form a stable colloidal state, which is not easy to be deposited on the parts.

2.Cleaning gels, carbon deposits, etc. It is deposited on engine parts by lubricating oil cleaning.

3.It is conducive to protecting the adsorbed molecules, maintaining the thickness of the oil film, and the first person is instructed to use it purely for a certain anti-rust author.

Introduction of lubricating oil additives:

Additives are mainly antioxidants, anti-wear agents, friction modifiers (also known as oily agents), extreme pressure additives, detergents, dispersants, antifoam agents, anti-corrosion and rust inhibitors, flow point improvers, viscosity index improvers and other types according to their functions. The additives sold on the market are generally a combination of the above single additives. The difference lies in the different components of a single additive, and the ratio of several single additives within the compound additive is different.

The use of engine oil additives is as follows:

New cars within 10,000 kilometers do not need to be used, at this time the engine is in good condition, unless there is a condition of engine quality, noise, power and other abnormal conditions, it is necessary to add.

2. For engines with a mileage of more than 50,000 kilometers, the use of engine oil additives can play a protective role, prevent wear and reduce carbon deposition and sludge production.

3. The engine with a mileage of more than 100,000 kilometers will wear a lot of wear, the engine noise will also increase, and the power will begin to decrease, the vibration will increase, etc., and it is necessary to repair the slight wear and enhance the sealing.

4. Many vehicles burn engine oil at 8 to 100,000 kilometers, and oil additives can alleviate or improve slight engine oil, and can also avoid the occurrence of cylinder pulling due to serious oil loss.

It is mixed with base oils and additives. Most base oils are obtained from petroleum through a proper refining process, technically known as mineral base oils. There is also a small amount of base oil that is artificially synthesized by chemical reaction of organic matter, which is professionally called synthetic base oil.

Lubricants are chemically synthesized products that are used to enhance the properties of base oils such as oxidation, anti-wear, anti-foaming, anti-rust, anti-corrosion, improving viscosity temperature, fluidity and clean dispersion. to meet the requirements of vehicle lubrication and maintenance under different conditions.

Do you need additives in oil?

In the lubricating oil, the base oil generally accounts for more than 85%, and the rest are various types of additives, which have undergone rigorous physical and engine bench tests, and have been carefully balanced and blended. At present, there are many kinds of oil strengthening additives on the market, some claim to have anti-wear repair function, some emphasize the cleaning and decontamination function, and some advertise that they can restore the power of the engine. Even if it's a lot of money, it should be said that some of these products do make users feel like they have some features to a certain extent.

It should be said that they are temporary measures for different vehicle conditions, but there are still some things worth scrutinizing. Lubricating oil experts revealed that high-quality engine oil already contains antioxidants and corrosion inhibitors, detergents, dispersants, anti-wear agents, oily agents, rust inhibitors, pour point depressants, defoamers and other additives. These additives are strictly balanced in formulation, that is, the comprehensive performance of the additive with good buried formula in the engine is evaluated through a large number of laboratory simulation tests, engine bench tests and driving tests, rather than unilaterally emphasizing some single performance.

Some additives simply cannot be targeted at the user's original oil formulation, and after rigorous adaptability testing, it is entirely possible to break the balance of the original formulation, resulting in a change in the quality of the engine oil and a decrease in the quality of the engine oil. Therefore, well-known lubricant companies do not advocate users to add lubricant additives casually.

Therefore, the average user should ask a few more question marks when the merchant sells you some lubricating oil fortifying additives, and the cost of adding these fortifying additives at one time is even higher than the cost of changing a high-grade oil. Vehicle maintenance experts said that as long as you choose the right lubricating oil for the hosiery chain to match the engine, buy reliable well-known brand products, usually do a good job of vehicle maintenance and oil change as required, and do not add such additives, it is entirely possible that the car engine will not be overhauled for life.

1. Moderate dosage.

Most of the transmission components such as transmissions, reducers, and steering gears of motor vehicles are oil-immersed. If the lubricating oil filling exceeds the specified limit, the stirring resistance of the gear during operation will increase, which will cause power loss and increase fuel consumption. Therefore, the amount of lubricating oil must be moderate.

In addition, some people stuff the inner cavity of the wheel with grease when maintaining and repairing the wheel hub bearings of motor vehicles, thinking that the more grease, the better. In fact, adding too much grease to the wheel hub will have many adverse consequences, one is to increase the running resistance of the bearing; the second is to affect the heat dissipation of the bearing; Third, the grease melted due to high temperature may penetrate into the brake drum and cause motor vehicle brake failure. Therefore, "hollow hub lubrication" should be implemented, that is, only grease needs to be applied on the bearing, and no grease is stuffed in the cavity, which can not only ensure the lubrication effect, but also save 5 grease.

2. Control the viscosity.

In fact, high-viscosity lubricants can increase mechanical friction losses. Especially at start-up, because the oil has poor fluidity at low temperatures, the frictional resistance is large, which increases the power loss and increases the fuel consumption. If a lower viscosity lubricant is used, the friction consumption inside the oil can be reduced without increasing the wear of the parts.

According to the test, the viscosity of the engine oil is reduced by one level, and the fuel saving rate of the engine is 1%-3%. Therefore, lubricating oil with lower viscosity should be used on the premise of ensuring lubrication.

3. The price should be considered.

Some drivers want to save money, often only see the price of oil and immediate maintenance expenses, and ignore the increased repair costs in the future. When choosing a lubricating oil, the quality grade of the lubricant should be selected according to the speed, the size of the load, and the type of gear transmission. The performance indicators of high-grade lubricating oil are superior, so it can significantly extend the service life of the machine and the oil change interval, and reduce the maintenance cost.

Especially when a motor vehicle is fully loaded for a long time and works in poor road conditions, it is best to use a lubricant quality grade that is one grade higher than that specified in the manual.

The correct use of lubricating oil plays an extremely important role in improving the operating performance of the unit, prolonging the service life of the unit, and saving economic expenses. Therefore, it is necessary to pay attention to the following when using it.

1) Regular inspection and timely replacement.

With the passage of time of the machine, the lubricating oil in the refrigeration system will continue to change qualitatively, so regular sampling and laboratory analysis, or color and phase comparison inspection, when the oil quality changes to a certain extent, it should be replaced in time. Under normal circumstances, the lubricating oil in the refrigeration system should be changed once a year.

2) Oil change requirements.

Look for the brand of new oil change, it is best not to easily change the brand of refrigeration oil, and it is strictly forbidden to use general engine oil instead of refrigeration oil.

Before replacement, all the oil in the system is released, and some new oil is added, and all the old oil remaining in the system is washed and released, so as to prevent the original oil from destroying the performance indicators of the new oil and affecting the service life of the unit.

When changing the oil, try to drain the remaining oil from the oil cooler. Thoroughly remove sediment and rust in the oil tank and air extraction device, and disassemble, inspect and clean the oil pump and filter to ensure that the replaced lubricating oil is clean and pure, and well lubricated.

3) Precautions to be taken when using the product.

During the shutdown of the unit, when the lubricating oil and refrigerant coexist in the system, the oil lubricating oil should be energized and heated to keep the oil temperature within the specified range.

In winter, when lubricants and refrigerants coexist within the system, how they are managed should be determined by the type of aircraft. Centrifugal chillers, especially centrifugal chillers with R11 as the refrigerant, should keep the electric heater energized to stabilize the oil temperature within the specified range. The screw and piston chillers can not be energized to the electric heater, and then turn on the power supply of the oil heater before use, heat for 24h, and then start the machine.
