Oils with a high content of molybdenum. Pros and cons of adding molybdenum additives to oil

There are quite a few motor oils with molybdenum on the market today. Moreover, the amount of this component, its molecular structure and mechanism of action can be quite different.

On the Internet and among motorists, disputes still do not subside about how justified the use of molybdenum in engine oil is. Indeed, often lubricants with this chemical element are more expensive.

Let's try to figure out what molybdenum disulfide is in a lubricant - is it good or bad? We will also find out how this component helps lubricants protect the engine and whether it is worth paying attention to oils with molybdenum-containing additives.

Brief history of discovery

What is molybdenum? In its pure form, it is a gray metal powder or lumpy metal with a low coefficient of friction and thermal expansion, a high melting point and boiling point.

However, in its pure form, this metal is of little value in the motor oil industry. Much more interesting are some of its compounds with other chemical components.

Molybdenum Disulfide Powder

The unique properties of molybdenum disulfide (MoS2) were known as early as the middle of the 20th century. For the first time, documentary evidence of the real use of this chemical element outside of laboratory conditions refers to the military industry. In the 1950s, Americans added molybdenum additives to oils used for tank engines and military aircraft.

It was noticed that if the engine lubrication system was damaged and oil leaked, the equipment could work much longer “dry” until complete failure in the presence of molybdenum in the oil. This gave the tank a chance to leave the combat zone for repairs or the aircraft to fly to the airfield.

Later, oils with molybdenum began to be used in civil engineering. One of the highlights in the history of molybdenum oils is the founding of Liqui Moly.

In 1957, an enterprising German drew attention to a small vial of a strange liquid that was being sold in the part of Germany controlled by the Western Allies.

It was molybdenum disulfide used in military aircraft. The German, whose name was Hans Henle, bought the rights to use this composition and began to develop motor oils under the Liqui Moly brand.

MoS2 lubricants are not uncommon today. Molybdenum-based additives are used by many manufacturers of motor and transmission lubricants.

And technology has come a long way in the last few years. And these oils today are much more technologically advanced than they were before, and are devoid of many of the shortcomings of the first versions of molybdenum-containing additives.

How molybdenum disulfide works

The MoS2 molecule, as is clear from the formula, consists of one molybdenum atom and two sulfur atoms. Easily combines into a film with a thickness of one molecule. Attracted to metal surfaces.

Crystal lattice of MoS2 film

Due to these qualities, molybdenum disulphide quickly spreads over the metal surfaces inside the engine and forms a thin surface layer. The film formed during the mutual displacement of the layers relative to each other has a very low coefficient of friction. At the same time, the strength of the film itself and its adhesion to metal surfaces is very high.

In the event of shock loading or thermal decomposition, the damaged area is filled within a short time with free molecules of molybdenum disulphide present in the oil volume.

Advantages and disadvantages

Like any additive, pure molybdenum disulfide has pros and cons. Consider first the benefits of using molybdenum additives in modern motor oils.

1. Reducing the coefficient of friction in mates. This is one of the most significant and determining the popularity of car oils with molybdenum properties. The low coefficient of friction increases the efficiency of the engine, increases its power and throttle response, and reduces fuel consumption.
2. Increasing the protective properties of rubbing surfaces. The protective film protects metal surfaces from dry friction during mechanical load fluctuations.
3. Rapid formation on metal surfaces and the ability to restore the integrity of the film in case of damage.

Influence of the amount of triatomic molybdenum on the coefficient of friction

Today, oils with molybdenum disulfide in its pure form are practically not produced. And there are several negative reasons for this.

1. Molybdenum disulfide in its pure form begins to form molecular bonds even before contact with metal surfaces. This leads to the formation of coarse particles, which have a density higher than that of the oil. If the engine is idle, molybdenum particles settle to the bottom of the sump and do not participate in operation for some time after the engine is started.
2. After pouring new oil, molybdenum forms a protective film on all metal surfaces. The remaining molecules circulate freely in the volume of the lubricating fluid. Being a compound that is not the most stable, molybdenum disulfide gradually decomposes into non-functional compounds and can no longer participate in the protection of engine parts.
3. In some cases, an excess of molybdenum disulfide does not work for the benefit, but harms the engine. To increase the service life, manufacturers increase the concentration of this component in the oil. Some of the molecules bind on metal surfaces to form a film. The rest circulates through the system and settles in the form of clots in the most inconvenient places: in the gaps of the piston rings, on the sensors, in the bends of the oil lines. Often these precipitations lead to unpleasant problems.

Features of the work of molybdenum additives in modern oils

Most modern motor oils do not use molybdenum disulfide in its pure form. The effectiveness of lubricants using additives based on pure MoS2 has shown to be inefficient and uncompetitive.

Modern oils are not considered in terms of individual modifiers used to improve performance. Additive manufacturers primarily make formulations that have complex characteristics and do not focus on individual components.

Under these conditions, the use of molybdenum required the development of new methods for the delivery and introduction of this component. And such a solution was found in the use of a complex complex based on diatomic (Mo-DTC and Mo-DTP) and triatomic molybdenum organic components in conjunction with a zinc modifier (Zn-DTTP).

Molybdenum is added to oil as a complex molecule that is quite resistant to breakdown. However, under the influence of the zinc component, temperature and some other factors, complex molybdenum compounds gradually decompose to the familiar MoS2. Moreover, this reaction in time is quite predictable and lends itself well to calculations.

It turns out that the addition of molybdenum dioxide is carried out in portions. Such a mechanism allows you to throw in small portions of active molybdenum throughout the entire life of the engine oil and fill in the gaps on the exposed friction surfaces. Also, this technology minimizes the negative effects of the use of molybdenum-containing oils.

Therefore, today the use of modern molybdenum-containing lubricants manufactured using the latest technologies is more than justified. But before using them, you need to carefully read the operating instructions for the car. For some engine modifications, the use of such oils is contraindicated.

Motor oils with molybdenum

Despite all the disadvantages, the advantages generally prevail. And today on the market you can find many brands of motor oils with molybdenum. Let's briefly consider not individual oils, but some manufacturing companies that use additives with this component.

A visual test of the work of molybdenum in Mannol engine oil - video

• . Perhaps the most famous company that uses molybdenum-containing additives in their products. It was on this component that the entire marketing system was built at one time, which allowed the company to become world famous almost from scratch in a few years.
• Mannol. Inexpensive motor oils that use molybdenum.
• Exxon Mobil. Uses molybdenum in some of his oils. In general, these lubricants are known for their innovative approach and the search for new solutions.
• Idemitsu. These lubricants use organic molybdenum compounds, which are the most stable.

To one degree or another, molybdenum-containing additives were used by many manufacturers of motor oils. Now this technology is in limbo. Many actively develop and promote it. Others, on the contrary, abandoned the prospect of using this component in their products.

The opinions of car owners regarding the composition and performance of the molybdenum additive often differ. Some argue that the molybdenum additive added to the oil significantly reduces the duration of the motor. Others say that, thanks to this tool, the car engine starts to work much better.

Why are molybdenum supplements good?

Every day, the requirements for harmful emissions are becoming more and more stringent. Existing regulations apply to both vehicle manufacturers and consumables manufacturers. Molybdenum is used in those places of rubbing elements where an oil film does not form. Thus, the absence of anti-friction layers is compensated.

Molybdenum additives are endowed with the following properties:

• The formation of scuffs, chips and metal chips is minimized;
• Engine oil improves its lubricating properties and wear resistance.

Today, motor oil often contains anti-friction compounds. Molybdenum interacts remarkably with sulfur, which contributes to good adhesion to the piston or any other rubbing surface. At the same time, the film layer in the motor increases, and lubrication characteristics increase.

It is known that when molybdenum is added to the technical fluid, the friction between the metal surfaces of the motor components decreases. In this case, the interaction of the metal with other components is completely excluded. Increased wear of rubbing surfaces at those moments when the engine reaches its maximum operating temperature also becomes impossible. This helps to increase the duration of the components and, accordingly, the entire motor as a whole.

How does molybdenum supplement work?

When molybdenum is mixed with the technical fluid, there is no spontaneous deposition on the treated area and even on elements such as the hydraulic lifter. The thinnest layer is formed, which in no way overflows the gaps and does not contribute to the disruption of the normal circulation of the technical fluid. Such a film formation can fulfill its main function only when the intensity of build-up and wear of the components remains approximately the same.

Naturally, such an effect is possible only with the regular addition of molybdenum additives to engine oil or during the operation of a lubricant containing the component in question. When the car owner switches to ordinary oil, having stopped using products containing molybdenum, the film wears out over time and components begin to wear off as easily and quickly as before.

It is for this reason that manufacturers of modern motor oils often add substances like molybdenum disulfide to their products to increase the possibility of forming additional shockproof layers.

Molybdenum-based additives in the form of a separate liquid substance are gaining more and more popularity with drivers who want to improve the performance of engine fluids in the fastest possible way.

At the same time, molybdenum disulfide is often used in other industries:

• For lubrication of certain varieties of production materials;
• Added to plastic formulations to improve density characteristics;
• In the production process, if necessary, the use of certain mechanisms in conditions of high operating temperatures.

Negative characteristics of molybdenum disulfide

If we refer to the data obtained as a result of numerous studies, we can conclude that combustion products of fuel can be deposited in the area of ​​\u200b\u200bthe piston rings. This leads to violations of the functionality of all elements of the cylinder-piston group, the occurrence of gas gusts, an increase in the thermal load on the components and an increase in the amount of unwanted deposits. For this reason, some manufacturers insist that the base use of oil products containing disulfide is undesirable.

After such recommendations, many drivers have an acute question in terms of choosing the right means to reduce friction between motor components. In such situations, synthetic esters often come to the rescue, which in their physical characteristics resemble castor oil. Their use contributes to an increase in adhesion abilities, as well as lubricating properties through the formation of a thin, but sufficiently dense and stable layer.

Increased thermal stability and the ability to adapt to sufficiently high operating temperatures is considered another advantage of lubricants with a sufficient content of synthetic materials. The operation of molybdenum additives is considered very appropriate when it is necessary to extend the period of possible operation.

A positive effect from such substances can be achieved even under conditions of absolute oil starvation of tank vehicles, but for cars it is imperative to fill in new oil more often if it is planned to add a molybdenum additive to the engine.

What oils should not be used?

Some lubricants contain too much calcium. When in contact with molybdenum additives, this substance does not allow additives to be deposited on metal surfaces. This causes the formation of large molecules that collect on the oil filter. It can be concluded that an insufficient amount of calcium additives contributes to the accelerated contamination of the motor, despite the improvement in the lubricating effect.

If car owners have the desire to use such additives, combining them with oils containing a lot of calcium, the risk of engine failure and quite severe pollution increases.

Molybdenum disulphide engine anti-friction additive

Summing up

Molybdenum disulphide is considered to be a very useful agent for automotive engines and will always be in demand by drivers who want to quickly improve the performance of their vehicles.

Molybdenum additives can be poured into the motor only if the technical fluid is replaced in a timely manner. It is necessary to ensure that new oil is poured regularly. The service life of lubricants with the addition of such additives is significantly reduced, since the oil very quickly begins to lose its quality characteristics.

And a little about the secrets of the Author

My life is not only connected with cars, namely repair and maintenance. But I also have hobbies like all men. My hobby is fishing.

I started a personal blog where I share my experience. I try a lot of things, various methods and ways to increase the catch. If interested, you can read. Nothing more, just my personal experience.

Attention, only TODAY!

For some time now, technical lubricants with a molybdenum component have appeared on the market for automotive consumables. In most cases, the presence of molybdenum in engine oil is served as a chip, thanks to which the lubricant composition receives excellent qualities. On the one hand, this is true, on the other hand, more and more often come across reviews of its harmful effects. Let's try to figure it out.

MoS2 is commonly used in the steel industry. Its positive properties include:

• Protects against corrosion;
• Heat resistant;
• It has good viscosity.

These characteristics are of interest to manufacturers of motor oils. They began to include it in the composition of the liquid. Such oils, in addition to molybdenum, have a large number of special additives that help the engine run smoothly.

Today, the composition of the newest motor fluids includes molybdenum disulfide. There is no unambiguous opinion about its influence on the operation of the engine. The fact is that the presence of this substance affects different brands of cars in different ways.

The principle of operation of molybdenum

All actions of MoS2 resemble the work of graphite particles. It is based on a graphite platform, which looks like the thinnest plate. The compound consists of two sulfur atoms and one molybdenum atom. The result is a strong bond. Such a tool has a powerful anti-friction function. The composition of the oil includes:

• Ceramics;
• Esthers;
• Graphite.

The molybdenum component is also available as a separate additive. It can be added to oil to improve its technical characteristics.

The positive effect of molybdenum

When creating engine oil with molybdenum, all the requirements of car manufacturers were taken into account. Therefore, such products have a number of very useful advantages:

• The use of friction modifiers increase energy-saving characteristics;
• Prevents the appearance of scuffs;
• Protects against increased wear;
• Excellent anti-friction performance;
• The friction force is reduced;
• Prevents engine overheating.

In principle, sulfur molecules are not capable of creating a powerful compound, but together with MoS2 a powerful bond is obtained. When such a substance enters the motor fluid, metal surfaces begin to become covered with durable protective layers.

The lubricating fluid contains a minimum amount of it, so it does not affect the operation of the valve system, the working process remains stable.

Modern lubricants contain many special additives. This allows the molybdenum disulfide to form an additional lubricating layer. It takes effect if the performance properties of the standard fluid change. Molybdenum disulfide is sold today in auto chemical departments.

When mixing specialized oil with MoS2, the properties of the car oil are noticeably improved. Molybdenum is able to work at very low or high temperatures. Ordinary lubrication is not capable of performing such actions.

MoS2 with sulfur is able to withstand 400 degrees. Such an additive can be used in other extreme conditions. It has found application in precision mechanics, it is added to various plastic materials.

Negative points

There is an opinion that molybdenum additives are better used in large power plants. They are completely unsuitable for gasoline systems. The reason is simple - the particles of the compound of molybdenum and sulfur are quite large. They can get into the area of ​​\u200b\u200bpiston rings, which will lead to failure of the engine itself.

Molybdenum additive grease, when the temperature reaches high values, increases coking. As a result, the operation of the piston system is disrupted. Exhaust gases begin to pass through it, thermal loads increase. The engine needs to be repaired. It is this factor that hinders many world concerns from recommending the widespread use of molybdenum additives.

To reduce the friction force, it is impossible to do without a synthetic base. It should consist of artificial strong esters, the properties of which are similar to castor oil. Such additives have become common in racing cars, as they are able to withstand high temperatures.

In the composition of the latest lubricants, a considerable amount is occupied by calcium, which reacts aggressively with MoS2. This happens much before the substance has time to cover the metal surface.

Before purchasing a molybdenum additive, a motorist should find out all the positive and negative characteristics of this substance. By adding molybdenum disulfide to the lubricant, engine operation can be disrupted.

If the composition of the technical solution does not include detergent additives, the molybdenum additive will reliably protect the fuel system of the machine. In wartime, molybdenum was used as a lubricant for tanks. In the event of an unexpected leak of lubricating fluid, molybdenum saved the engine. He continued to work. This effect arose due to the absence of special detergent additives in the oils of military equipment.

The conclusion is clear. Molybdenum can be added to oil when there are no detergent additives in its composition.

Is there motor oil with molybdenum? The answer is yes - such a substance is often present in the composition of modern lubricants. Molybdenum is a predominantly light gray substance that often finds its main use in industry and metallurgy. The element has strong heat resistance and corrosion resistance, good toughness. Such characteristics attracted the attention of car oil manufacturers to it, and it began to be widely used as part of lubricants. Probably, for people who are poorly versed in chemistry, this name will not say much, but motorists have to solve a dilemma that can be formulated as follows: should motor oil be used, which contains molybdenum?

Oil with molybdenum has the widest composition of additives needed for stable engine operation.

Brief description of the element

Many modern automotive oils contain molybdenum disulfide compounds. Estimates of the impact of the product on the fuel processing system of the vehicle are completely opposite - from enthusiastic to very restrained and negative. The difference in estimates is explained by the fact that the substance affects different brands and models in different ways. Until now, it is very difficult to determine which types of engines have defects due to molybdenum, and which do not.

How does molybdenum work?

The system of action of the MoS2 substance in motor oil is actually very similar to how graphite particles work. The molybdenum substance is based on a graphite lamellar platform. The compound contains one molybdenum atom and two sulfur atoms, which form a very strong bond. The combination of sulfur and molybdenum is actually quite strong. The size of the sulfur atoms is about the same as the size of the metal atoms, which gives the combined mixture a good protective function. And without molybdenum, such harmony would not have happened.

It is worth noting that the tool has an anti-friction function. Today, almost all oil manufacturers pour such anti-friction compounds into the composition of their various products. These include graphite, esters, ceramics, etc.

How does molybdenum affect?

Molybdenum has strong heat and corrosion resistance and good toughness.

So how does the agent of interest to motorists affect engine oil and the entire lubrication process? The product with the composition of molybdenum disulphide was created in compliance with the highest requirements for manufacturers of technical parts and the lubricants themselves. Among the benefits that the car owner receives along with the purchased product are very useful:

1. The use of friction modifiers, which help to create anti-friction juices, the compounds of which, being in the areas of oil film damage, give the oil element energy-saving characteristics.
2. Molybdenum disulphide has extreme pressure properties and prevents equipment wear.
3. The use of special friction stimulating modifiers creates conditions for the appearance of antifriction barriers in the zone of oil film breaks. All this gives them energy-saving properties.
4. The process of friction and overheating of metal parts is reduced.

The sulfur molecules themselves form a too weak compound, therefore, merging into the MoS2 compound, the two elements form a very powerful bond. When an element is added to a lubricating fluid, metal surfaces are simply covered with certain layers that have a protective function. Molecules move relatively quickly apart from each other. As a result, direct contact of metal with another metal is excluded.

The substance has a very small proportion in the lubricant. Given the working clearances in the engine area, it cannot interfere with the workflow in any way. Modern oil with molybdenum has the widest composition of additives. They allow the molybdenum disulfide to create another lubricating layer. This layer comes into play when the standard grease loses its performance properties. Molybdenum disulfide additives are today produced as a separate auto chemical product. These compounds can be added to specialized oil, improving its properties. Molybdenum elements can work where conventional lubrication does not - during exposure to high or low temperatures. The compound of sulfur and molybdenum is able to function at a temperature of 400 degrees Celsius. The additive is suitable for use in other extreme situations. Grease containing molybdenum disulphide is excellent for use in precision mechanics and as an additive for working in plastic materials.

Skeptical assessments

Molybdenum elements can work where conventional lubrication does not - during exposure to high or low temperatures.

To be as objective as possible, it should be noted that the tool has a downside. It does not always appear, but some motorists are very reserved about oil with an admixture of molybdenum disulfide:

1. There is an opinion that molybdenum elements are better suited for large and very large propulsion units. They are not suitable for powerful gasoline devices. Indeed, in fact, motor oil with the addition of molybdenum disulfide is not a standard compound of elements that enter into a chemical reaction, but, on the contrary, a physical mixture. The particle sizes of the compound are very large, they fall not only into the necessary friction zones, but also where they should not, for example, in the area of ​​​​piston rings.
2. A lubricant containing molybdenum elements in its composition enhances coking or the deposition of burnt products at fairly high temperatures. This in turn leads to damage in the area of ​​the cylinder and piston. This is almost always followed by a surge in the activity of gases entering the oil by penetrating through the piston ring area. All this inevitably entails thermal loads, technical malfunctions and repairs. This fact largely explains why molybdenum disulfide is very reservedly recommended by some automotive concerns.
3. Reducing the friction process is actually possible only with the use of a number of basic synthetic substances. We are talking about the so-called esters, made from synthetic materials, very potent substances, which in their properties are almost the same as castor oil. They are more often used on racing units, have an adhesive property, and have a high thermal function. Skeptics believe that it is these synthetic additives that provide optimal friction, and not molybdenum sulfide.
4. Modern oils contain too much calcium. Calcium enters into a very harsh and aggressive reaction with molybdenum disulfide, and before its elements settle on metal surfaces.

As a result, skeptics conclude that there are two most important reasons why oil with molybdenum today is not a very good choice:

1. Too high requirements for the purity of the lubricant. Molybdenum works well just in slightly refined oil.
2. The presence of calcium, too hostile to molybdenum disulfide.

If not for these two factors, molybdenum would still be an excellent lubricant additive to this day.

After carefully evaluating the positive and negative assessments of the product, all its pros and cons, the motorist must decide for himself whether to purchase this product or not. After all, we are talking about the technical serviceability of the car. Molybdenum disulphide can serve both as a cause of defects and as a reliable protection for the fuel distribution system of a car. It is believed that molybdenum disulphide molecules would be good to use today without the presence of various detergent additives. As an argument, the fact is given that in the 40s, during the Second World War, the agent was used as a lubricant in tank units. If an extreme oil leak occurred, the engine could run for a certain time due to molybdenum compounds. In military equipment, oils did not have detergent additives. From this, however, it is concluded that this is their strong disadvantage in their civilian use, where detergents are constantly used.

Molybdenum additive for the motor causes controversy among motorists. Someone believes that molybdenum disulfide has some advantages, it improves the functioning of the engine. Other drivers believe that this additive reduces the operating period of the power unit.

So how do the molybdenum additives that are added to motor oil actually work?

Pluses of an additive

The requirements for emissions into the atmosphere and fuel consumption are getting tougher. They refer to manufacturers of both motor oils and cars. To restore antifriction layers in areas with a broken lubricating film, molybdenum disulfide is used, which has the following properties:

• minimizes the number of scoring in the engine;
• improves engine lubrication;
• reduces wear.

Seizures in the engine cylinder

These additives are present in many lubricants manufactured today. Organic molybdenum interacts well with sulfur. This gives him the opportunity to securely attach to the piston or other moving part that requires high-quality lubrication.

Molybdenum-based oil additives are known to reduce the friction of contacting parts. As a result, engine wear is significantly reduced. You need to repair the engine much less often.

The effect of molybdenum disulfide

Molybdenum additive does not deposit on motor parts. It forms a thin film that does not overfill the gaps, does not interfere with the circulation of the lubricant. The film is formed only if you regularly use, for example, the additive Liquid Moli with molybdenum. When a motorist stops using the powder and starts pouring ordinary car oil, the film is subject to wear. Because of this, the number of scuffs and wear of the motor increases.

Motor lubricants produced today resist scuffing and wear well. Thanks to automotive additives Liqui Moly, "Hado", "Mannol" it is possible to form repeated anti-shock layers.

Liquid moth additive

In addition to conventional drivers, Liqui Moly additives are used:

• in production carried out in high-temperature conditions;
• for lubrication of various materials;
• to increase the density of plastic substances.

Cons additives

According to the results of many studies, Liqui Moly additive can be effectively used in production units. If the engine is often run at high speeds, particles of molybdenum can penetrate into the piston rings.

With constant operation in high temperature conditions, combustion products settle on the pistons. The engine starts to function differently than before. Gas gusts appear, the thermal load increases and, consequently, the number of deposits. In view of this, some car manufacturers do not recommend the use of additives. What if the motorist wants to reduce friction in the engine?

You can use complex ether synthetics, which are similar in physical characteristics to castor oil. What is it for and what does it give? Its use increases adhesion, improves lubrication by forming a thin and durable film. The main advantage of lubricants containing ester synthetics is thermal stability. It is worth mentioning that molybdenum additives are often used to increase the operational period of military equipment motors.

Carbon deposits from oil and additives

Today, oils contain a considerable amount of calcium. It does not allow molybdenum particles to settle on the surface of the parts, as a result, large molecules appear that collect on the oil filter. The loss of calcium elements is one of the causes of contamination of the power unit. In view of this, if a motorist wishes to use a molybdenum additive, he must fill the engine with an oil product with an increased calcium content. Unfortunately, such vehicles do not yet exist.

If you "give" your motor a molybdenum additive, do not forget to change the lubricant in a timely manner. It will not work for a long time on an old car oil. The characteristics of the oil when using an additive are greatly reduced. If moisture gets into the engine, metal parts will quickly wear out and become significantly deformed.

Tribological means

According to the manufacturers of tribological products, their products are not considered an additive. They act by creating a friction-lubrication pair. A molecular lubricating layer is formed, which prevents wear of working motor parts. These funds "give" the engine along with the lubricating fluid.

When a film is formed, the following happens:

• abrasive particles that are in the tribological tool clean the motor;
• a protective layer is formed;
• thickness, porosity, other physical characteristics of the protective layer change. The hydrodynamics of the motor is improved.

Experts believe that tribological products are optimal for various engines, allowing them to work in harsh conditions, with oil starvation. In addition, if you "give" the power unit such a tool, it will work more powerfully by about ten percent.

Drivers must remember the right rule, namely: if you do not follow the instructions attached to the tribological composition, the engine may be damaged. Manufacturers also claim that such products reduce fuel costs. It is best to “give” such funds to the engines of new cars.

So why use such tools? Is it possible to do without all these disulfides and dioxides? The answer is yes, you can, as long as you use a high quality lubricant. It already contains all the necessary additives that significantly improve the functioning of the engine and extend its operating period. Remember that if used incorrectly, additives can harm the motor. Therefore, carefully read the instructions that come with the additive. So you will avoid unnecessary problems associated with the operation of the power unit.
