How to choose the best engine additives? Engine additives: which product is the best? Additive to motor oil to increase service life.

Do I need to buy and use engine additives? This question interests everyone who has a car older than 5 years. Objectively - it is necessary! A high-quality composition makes the life of the engine much easier.

Another thing is what kind of additive should I buy? It depends on the initial state of the engine. To improve the performance and increase the service life of new or slightly worn engines, it is worth choosing compounds from the group of geomodifiers. Engines from the “ordered to survive” series or in a pre-infarction state will need already potent compounds, which Liqui Moly and Bardahl specialize in. Such measures will not just delay the death, but will reduce fuel consumption, increase engine power and its service life.

What to choose and what compositions really work? The rating of the best additives for the engine and fuel system, based on reviews from motorists and real characteristics, will help you figure it out.

Additive categories

Depending on the purposes for which the engine additive is used, the following categories can be distinguished:

Anti-knock (correcting octane and cetane numbers)

If the quality of gasoline is poor, peroxides appear in the fuel mixture, which are dangerous because they burn before combustion of the fuel mixture begins. As a result, the temperature in the combustion chamber rises to critical levels, which leads to engine detonation, and anti-knock additives prevent engine detonation by destroying peroxides and preventing them from accumulating.

Depressants and dispersants

Depressant additives lower the temperature threshold at which the oil begins to solidify. Mostly they are poured into the engine with winter motor oil, but there are diesel additives that are added to the car’s fuel tank, which prevents the fuel from solidifying. Dispersants, in turn, are poured only into the tank and prevent stratification of diesel fuel and prevent the formation of paraffin deposits. Depressant additives

Viscosity-increasing oils (thickeners)

Used to increase viscosity. The fact is that during operation of the engine, some parts of which are susceptible to friction, wear out, for example, components of the cylinder-piston group, which leads to an increase in the gaps between them. Because of this, oil enters the combustion chamber and smoke appears while the engine is running. It is the use of these additional substances that increases the viscosity of the oil and prevents it from entering the combustion chamber.

With anti-friction coating

They are used to prevent the appearance of scuffs on the cylinder walls of an internal combustion engine and to reduce the gaps between rubbing pairs. It also reduces noise during engine operation and reduces the amount of toxic substances in exhaust gases. In addition, these compounds trigger the “wearlessness” process, discovered quite a long time ago by Russian tribologists and called the Gorkunov effect. In other words, the chemistry acting on the surfaces converts wear products into an ionic state and then deposits them again in wear zones.

Preventing the oxidation process (inhibitors)

Protective additives that are used to prevent corrosion of metals that come into direct contact with fuel. This additive displaces the water film from the metal surface, thereby preventing the metal from oxidizing.

Engine restoration additives are most often poured into engine oil. According to their properties, they cope excellently with accumulated dirt, carbon deposits and tar deposits inside the engine. Thanks to their use, the working life can be increased by 30-40% and oil consumption can be reduced by exactly the same amount.

FENOM FN 710

Organometallic additive for Phenom motor oil to protect against wear and restore the performance characteristics of gasoline and diesel engines. Restores microdefects of friction surfaces. Increases the wear resistance of engine parts during periods of overload and oil starvation, reduces mechanical losses, fuel and oil consumption, increases and equalizes compression in the engine cylinders.

Interacts with contaminants at the molecular level, most effectively cleans the internal surfaces of the internal combustion engine and its power system from soot and deposits.

The engine additive is excellent for new cars, for engines with high mileage and for newly restored engines that require running-in (for example, when restoring vintage cars). Liquid Molly Keratec contains a suspension of solid microceramic lubricant based on hexagonal boron nitride in mineral oil. The laminar, graphite-like structure reduces friction and wear and prevents direct metal-to-metal contact—ceramics work similar to balls in ball bearings. A durable surface layer with inclusions of ceramic microparticles is also created, protecting the engine under high load conditions.

Advantages include complete miscibility with all commercially available motor oils. The additive does not settle and passes absolutely freely through all commonly used filter systems, resists extremely high and low temperatures, improves engine smoothness and prevents engine damage as a result of extreme circumstances (oil leaks, very high loads, overheating). The effect of Liqui Moly lasts up to 50,000 km. The compositions Cooper, Mannol, etc. work on the same principle.

The tribotechnical composition forms a protective layer with a special structure on the surface of metal parts. In fact, the size and geometry of worn parts are restored, the gaps in friction pairs are reduced, due to which the oil lingers longer on surfaces subject to constant friction. The most important effect of using the additive is an increase in power and fuel economy by 6-8%.

Among other things, oil waste is reduced, since the protective layer restores the density of the liner-ring assembly; accordingly, oil removal from the cylinder walls is improved and its waste in the combustion chamber is reduced, especially at increased engine speeds. Vibration and noise are reduced, the internal combustion engine runs smoothly.

An excellent bonus is easier starting and protection during cold starts, since the treated surfaces are able to retain the oil layer during long periods of inactivity. Protection during active driving - treated surfaces retain a denser oil layer, which reduces wear and compensates for oil starvation during moments of rapid engine speed.

They allow you to temporarily get rid of a significant amount of exhaust gases and strong noise that occurs during the operation of the internal combustion engine. This is not a repair, but only a disguise of problems, which is often used when selling used cars. But if you really want to solve the problem, you first need to measure the engine compression and use decoking agents. Further measures are taken depending on the condition of the “patient”.

Oil Additive Liqui Moly

The anti-friction additive with molybdenum disulfide in motor oil is excellent for cars of previous generations, and the effectiveness of the additive has been tested for decades. Fully stabilized and designed for use in diesel and gasoline car engines. Compatible and miscible with all types of motor oils (mineral, semi-synthetic, synthetic).

Allows you to increase the service life of a worn-out engine and delay major engine repairs by several thousand km. Thanks to the content of a second-generation synthetic metal conditioner, SMT2 reduces friction and wear on engine parts.

Among other things, the complex restores the detergent, anti-foam, extreme pressure, and viscosity properties of the oil, improves the package of protective additives it contains, prevents oxidation and dilution of the engine oil under peak loads, as well as the breakthrough of gases from the combustion chamber into the crankcase. A very big plus is that rupture of the oil layer between rubbing parts, scuffing and wear are eliminated, and smoke and oil waste are reduced by 2.5-3 times.

Rimet additives are among the best domestic auto chemical products. They are able to protect the car from wear and tear and delay mandatory major repairs of the engine and gearbox. Products are presented in a wide range depending on function and purpose. This is achieved by restoration by washing and applying a protective layer to the internal surfaces of the motor.

The healer is made on a base synthetic oil without additives made in Germany, compatible with all types of synthetic and semi-synthetic oils. The uniqueness of the drug is that it significantly reduces friction and increases engine power, depending on the degree of wear, up to 20%, while at the same time being a protective and restorative drug. Reduces engine noise. Eliminates wear at the earliest stages of engine operation. Significantly increases the life of a worn engine.

Objectively, it is almost impossible to increase compression in an engine without disassembling it. You can, as an option, use various additives that extend the life of the engine, but only for a while. These are synthetic lubricants that reduce friction between moving parts, something that conventional oil cannot achieve.

Resources

The principle is based on creating a film of small particles that envelop the surfaces of parts and the walls of unit components. Compacted gaps increase the efficiency of the power plant and provide an increase in power.

This group of additives affects the entire system, cleaning from the fuel tank to the injectors. In this case, carbon deposits are removed from the surfaces of the combustion chamber and other elements.

Suprotec Active Plus

It is used for any gasoline and gas engines (including forced and turbocharged ones) with a mileage of over 50 thousand kilometers, that is, those that have been fully run-in. The average cost of one 90 ml bottle is 1,400 rubles. One bottle is enough for one stage of engine treatment with an oil volume of up to 5 liters. For engines with an oil volume of up to 10 liters, 2 bottles are required. For normal processing in 3 stages, 3 or 6 bottles of the product are needed, depending on the engine size. Detailed instructions are provided on the official website.

Suprotec Active Plus

Suprotek attachments are the best protection and restorative agent for serviceable automobile engines operating in various conditions. Of course, no composition will remove the bullies, no matter what the manufacturers promise, but Suprotek does not allow new ones to appear. Also, a 100% effect is observed if you need to clean the engine from dirt. Pouring additives into a fully functional engine increases its service life under normal conditions by 60%.

Designed to activate the catalytic fuel system with catalyst metal ions. This contributes to more complete and high-quality combustion, an increase in power and a reduction in fuel consumption by up to 25%, a reduction in CO/CH and soot in the exhaust gases, a reduction in the likelihood of valves and pistons burning out and an increase in the service life of spark plugs.

It is recommended to use regularly. For more rational use, use the “3 in 2” scheme (3 times in a row for 3 full tanks, followed by skipping 2 applications), since the composition has a prolonged effect on 2 subsequent full fuel tanks, that is, a total of 500 liters

An effective system for flushing the fuel system of gasoline engines using any cleaning solvent. In the process of cleaning the injector, the parts of the cylinder-piston group and valves are also washed and coke deposits in the working part of the injectors are reduced, which entails fuel savings and restoration of engine power.

The kit includes corrosion-resistant tubing, which allows you to work with any cleaning solvent for fuel systems. Works with any source of compressed air - a pneumatic line or a regular household compressor for inflating tires. The kit includes a pressure gauge for monitoring pressure and a reducer for adjusting it. It takes about half an hour to wash.

Additives are used for diesel or gasoline engines due to the fact that the protective properties of conventional oil are often simply not enough. If operation is associated with difficult conditions, then the characteristics of the basic composition are simply not enough. Especially if the quality of the fuel initially leaves much to be desired.

Contains a high concentration of cleaning components, cetane-increasing additive and lubricating components, gently cleans the fuel system, protects against corrosion, improves fuel combustion, increases engine power and reduces diesel fuel consumption.

• increases the service life of the turbocharger, catalyst and particulate filter.

It is added directly to a full fuel tank and consumed to the end at high speeds (not lower than 3500).

VIDEO: Engine additives - to pour or not to pour?

Any engine has a limited operational life. It can be significantly extended by using special engine additives. They are made on the basis of mineral elements and synthetics. When engine rebuilding additives are present in an engine, they significantly reduce the rate of wear of parts that come into contact with each other.

There are many different additives available in stores from different manufacturers. Not all of them have a positive effect on the power unit. The selection of additives must be taken with full responsibility, because certain products can damage the engine.

Stages of engine wear

The working life of engines is expressed in mileage/motor hours. It is possible to distinguish four key stages of wear:

1. The first is mileage 0-15,000 kilometers.
2. Current – ​​mileage 15,000-60,000 kilometers.
3. Critical - mileage 60,000-120,000 kilometers.
4. Transcendent - mileage more than 120,000 kilometers.

At stage 1, there are no significant changes in car use. The cooling fan starts up a little more often. This is due to the fact that the rubbing parts expand unevenly.

Engine piston wear

At the current stage, the engine operates as dynamically as possible. Oil fluid costs may increase. This happens due to coking, which provokes the appearance of scuffing. To reduce wear, you need to change the engine oil frequently.

At a critical stage, a lot of carbon deposits accumulate in the oil drainage channels of the engine. Because of this, the temperature of the operating engine increases. The valve and rings may begin to burn. Motor oil costs are likely to increase significantly.

At the beyond stage, avalanche-like formations appear. Usually at this stage the engine begins to consume a lot of fuel. It is necessary to carry out repair work with troubleshooting of spare parts.

To reduce wear on a gasoline/diesel engine, it is necessary to use reducing additives. Thanks to their use, it is possible to increase the working life by thirty to forty percent.

How do motor restorative supplements work?

Engine rebuilding additives work quite simply. Essentially, these are catalysts. They significantly speed up crystallization on contacting parts. A special protective layer appears. It bears all the loads that arise during operation of the motor.

When using various additives, the crystal lattice is restored. One of the most common additives is “Suprotek”. Filling the engine with Suprotec can provide a significant reduction in friction of parts.

Additives reduce friction

There are oil additives that increase the lubricating characteristics of the petroleum product poured into the engine. Such additives may include Edial brand products.

The use of the above additives provides:

• alignment, a significant increase in compression in the cylinder block;
• increasing oil pressure;
• elimination of coking.

Nowadays, the use of wear reducing additives is considered a necessity. The use of such additives makes it possible to significantly reduce the frequency of major repairs. To choose the best additive for the engine, you need to take into account the type of power unit and motor oil.

Types of Additives

All currently existing additives can be classified according to their mode of action on contacting engine parts:

1. Viscous. Makes car oil thicker. Because of this, fluidity in low-temperature conditions increases and the lubrication characteristics of the petroleum product improve. Thanks to this, you can operate the car for a long time in harsh conditions. Typically, such additives contain polyisobutylene and polymethacrylate elements.
2. Anti-wear. Thanks to them, a special film is formed on the parts in contact, which reduces friction and wear. Such additives have a particularly good effect on crankshaft bearings.
3. Cleansing. They make it possible to restore the normal functioning of the engine by eliminating formations from spare parts. The number of oxides and sludge on metal parts becomes minimal.
4. Anti-corrosion. Reduces corrosive effects, fuel costs, and increases oil pressure.
5. Anti-friction. Reduce friction torque. Such additives need to be poured directly into the internal combustion engine.

How to choose a supplement

What should you consider when purchasing an additive? The type of additive is of great importance. For example, when using a motor in low-temperature conditions, it is optimal to use an additive that cleans the engine of slag formations and improves lubrication properties.

It is necessary to choose one or another additive, taking into account the recommendations of an automobile mechanic. There are many ways to diagnose a motor. You can measure pressure and examine spare parts using a special camera.

The manufacturer of the additive is considered an important factor. It determines how effective the additive will be. Currently, there are many supplements of various brands in Russian stores. You need to choose products manufactured by a reliable manufacturer that has proven itself well. It is advisable to read the reviews of those who have used the additive before. Drivers are in the best position to tell you the pros and cons of a particular additive.

Common Supplements

The following additives are popular today to reduce wear on oil seals and other engine parts:

• "Laurel";
• "Suprotek";
• "Hado";
• "Resource";
• "ER".

“Lavr” has been used by Russian drivers for many years. Especially good are the additives “Lavr”, which eliminate the accumulation of deposits from the oil drainage channels. According to the reviews of car owners who used Laurel additives, they really extend the service life of the engine.

"Hado" is a foreign company that produces high-quality additives that allow you to restore normal engine operation. Some argue that Xado supplements are ineffective. Others are confident that Xado additives perform their task perfectly. Often, the lack of effect from using the Xado additive is explained by non-compliance with the rules for using the additive.

"Resurs" is a Russian brand. These additives are effective when used in engines of any manufacturer. They reduce lubrication costs and increase traction at high/low speeds.

“ER” additives show excellent performance when poured into Subaru with boxer engines. They significantly reduce the noise of the engine and increase its service life. It is necessary to carefully monitor the dosage.

Separately, it is worth noting the additives “Liqui Moly”. They are more expensive than other additives, but provide excellent protection for the power unit installed in the vehicle.

Like any other unit, a car engine is subject to wear and tear during operation. This especially applies to cars manufactured in the Russian Federation. There is a method that allows you to extend the life of the power unit and all its parts. It consists of observing oil change intervals and using special additives.

What is the effect of engine additives? What features do they have? What are the benefits of using them?

Description

An additive is a product that is added to fuel or lubricant to improve vehicle performance. Currently, there are many types of these additives. Particular attention should be paid to anti-smoke, cleaning, anti-wear, anti-oxidation, and restorative additives.

Most additives for motor oils/fuel reduce fuel costs and restore dynamic performance and engine power. Additives are classified by method of use.

Gasoline/diesel additives significantly reduce fuel costs. Due to special components, they increase the characteristics of the fuel, its octane index, and eliminate excess condensate from the tank. When penetrating the engine combustion chamber, the product cleans the intake valves, chamber walls, and all parts of the fuel complex.

Engine restoration additives are usually poured into car oil. Thanks to their own characteristics, they perfectly remove accumulated dirt, carbon deposits, and tar from the engine. In addition, additives to motor oils reduce friction of contacting parts, increase the strength and wear resistance of the lubricating film, therefore, the internal combustion engine operates more efficiently. Many manufacturers advise adding additives to the engine for grinding in spare parts in a newly purchased car. Such products restore the cermet coating on worn parts of the engine. All this ensures the uninterrupted functioning of the power unit and extends the operating life of the pistons and cylinders.

Components

Reducing additives in engine oil are made from various elements. What additives are there? Such consumables can be divided into 3 categories:

1. Metal cladding. When they enter friction areas, a new cladding layer is formed. It can correct deformations that occur on the coating of metal parts due to wear of pistons and crankshaft bearings.
2. Mineral. They provide good restoration of cermets on motor parts and micro-grind steel parts.
3. Polyester, chlorinated paraffin. Such products are not as common as previous types of additives. They act as flushes, removing carbon deposits and contaminants from diesel/gasoline engine parts.

How additives work

What do the additives that are poured into the internal combustion engine provide? Getting into the car oil, they form a liquid crystal of metal ceramics. When the load on the motor increases (temperature and compression increase), this element works like welding, eliminating holes, protrusions, and cracks. A protective layer appears on the coating of the contacting parts. Research shows that alloying of grinding parts is carried out to a depth of 200 microns. This is due to the fact that modern oil additives contain nickel, platinum, tantalum and cobalt elements.

How do reducing additives differ from additive components in motor oils?

Any motorist knows that factory-made motor oils contain many useful additives. This is confirmed by manufacturers all over the world. They do not recommend mixing motor oil with other products. Mixing, they say, can change the composition of the lubricant. Experts believe that additives for restoring/cleaning internal combustion engines differ significantly. Let's find out why.

The fact is that the additives that manufacturers talk about are means that determine the performance of motor oil. This means that the lubricant is one continuous additive. Due to the fact that it is not very profitable for oil product manufacturers to disclose such information, they position their own products as oils that have a “balanced additive package.”

Effectiveness of restorative additives

Not long ago, on a popular motorists forum, the results of using a well-known product that is added to the VAZ-2110 power unit were posted. Before testing began, the power and pressure of the engine were measured using special equipment. Results: power – 61 hp, pressure – 8 kgf per square centimeter. After two thousand kilometers traveled, measurements were carried out again. The maximum power of the internal combustion engine increased by twenty percent, and the compression in the cylinder block increased to 12 kgf per square centimeter.

Popular Supplements

"XADO"

XADO is a Russian manufacturer of lubricants. Over the twenty years of its existence, it has become popular both in the CIS and other countries. Can you trust this company? It is impossible to answer this question unambiguously. There are many reviews that characterize the company both positively and negatively. The fact that XADO as an engine additive is the best is confirmed by drivers who have used it. In their reviews, they partially describe and analyze it, and share their impressions of its use.

The opponents are motorists who have not used XADO products. Their reviews do not contain specific information.

XADO additives

It is worth noting that XADO additives do not damage the engine. Select and use this product safely and effectively. Drivers claim that even after 300,000 kilometers the engine functions smoothly, does not stall, and does not smoke. The list of advantages is quite long.

Among the disadvantages, many motorists highlight the high cost of consumables. Indeed, XADO produces expensive additives. The cost of one ten milliliter tube is 300 rubles. To completely restore the power unit, you will need to spend about one and a half thousand rubles. No wonder - the best additive cannot be cheap.

"Suprotek"

One of the best types of supplements. Its purpose is to eliminate cracks and reduce fuel costs. Fuel consumption is reduced by ten to fifteen percent. The product copes with its task both in summer and winter. Moreover, it is inexpensive. A tube of a product called “Suprotek”, with a volume of ninety milliliters, costs one and a half thousand. This is almost half the price of XADO additives.

SUPROTEC additives

Selecting additive

What additive should I put into the engine? How to choose a cleaning/restoration product that will have the best compatibility with the motor? Consult with a specialist, for example, a store employee, an experienced driver. Ask which engine additive is best. Don't choose too cheap products. Better quality costs more. There are low quality additives. If you “give” them to the power unit, this may lead to the need for repair and restoration work.

The best engine additives are those recommended by your car manufacturer. Take the time to look at the operating manual. It should clearly indicate which additives are best to pour into the engine. It is not recommended to consider the rating of additives as the main criterion by which you select an additive. We will choose a high-quality additive to maximize the operational life of the internal combustion engine.

Each engine has a certain operating life. But it is possible to significantly increase it by using special compounds - additives. They are mineral and synthetic components. Thanks to their presence inside the engine, the wear rate of parts and rubbing components can be significantly reduced. If you have no experience in this area, you should consult with a specialist.

There are a large number of different additives on the market from different brands. Moreover, not all of them actually have a positive effect on the engine. The choice of additives should be approached with the utmost caution. Some can even harm the internal combustion engine.

Stages of engine wear

All mechanical devices have their own service life - expressed in mileage or engine hours (depending on the type of equipment). There are 4 main stages of wear:

• the first – with mileage from 0 to 15,000 km;
• current - with mileage from 15,000 to 60,000 km;
• critical - with mileage from 60,000 to 120,000 km;
• prohibitive - with a mileage of 120,000 km or more.

The first stage usually does not significantly affect the operation of the vehicle. It is characterized by slight changes in the operating temperature of a particular unit. The engine cooling fan may turn on a little more often. The reason for this is the uneven expansion of parts that come into contact with each other during operation. Gradually grinding of individual parts occurs.

During the second, current stage of wear, all parts naturally rub against each other due to grinding during operation. Usually at this stage of operation the engine shows itself to be the most dynamic. But some oil consumption may occur. The main reason for this is coking. As a result, scoring may occur. Frequent oil changes will reduce wear at this stage.

With a mileage of 60,000 to 120,000 km, critical wear occurs. A large amount of carbon deposits accumulates in special oil drainage grooves. Due to this, the operating temperature of the engine again increases. Valves and rings may begin to burn. A significant increase in oil consumption is possible. The rings may come into direct contact with the surface of the working cylinder.

With a mileage of 120,000 km or more, avalanche-like deposits appear. Usually at this stage the engine begins to consume significantly more than the rated amount of fuel. It is necessary to carry out repairs with defective parts.

The mileage limits indicated above are different for different engines.

It is important to remember: the use of additives will significantly reduce the rate of engine wear. When using certain compositions in accordance with the instructions, the service life before major repairs can be increased by 30-40% of the rating.

What causes engine wear?

In addition to the natural causes of wear and tear that are a consequence of normal vehicle operation, there are also other, additional ones. They have a fairly significant impact. Similar reasons include:

• frequent engine starts when the engine warms up at night;
• running in the engine after a major overhaul or purchasing a new vehicle was carried out incorrectly;
• there was overheating;
• coking.

The process of engine restoration additives is quite simple. Typically, such compositions are special catalysts. They significantly accelerate the crystallization process on the surface of rubbing parts. A special protective layer is formed. It is he who takes on most of the load during engine operation.

In the process of using various types of additives, the crystal lattice of metal components is restored. This is exactly how most formulations of this type work. One of the most popular at the moment is “Suprotek”. The main characteristics of the working layer directly depend on the conditions under which the operation takes place. If you look at a part coated with a layer of additive, you can see a mirror-like, smooth surface.

There is a separate type of additives - they increase the lubricating properties of the oil used for the engine. This is exactly the principle on which Edial products work.

Typically, the indicated types of additives should be used when deviations from normal engine operation occur after 60,000 -70,000 km.

The use of additives from the manufacturers indicated above allows you to:

• level out and also significantly increase the compression rate in all engine cylinders;
• increase oil pressure;
• remove coking from the surface of the hydraulic compensators without disassembling the engine.

The use of additives of various types is a necessity today. The use of such compositions will significantly delay the time of major repairs and reduce consumption. It is only important to prepare in advance for the process of selecting additives. Since there are many nuances and features - first of all, this is the type of engine, oil, as well as its brand.

The most popular types of additives

All compositions of this type on the market today can be divided into separate categories according to the method of exposure to the working surfaces of the engine:

• viscous;
• anti-wear;
• antioxidant;
• detergents;
• anti-corrosion;
• anti-friction.

Viscosity-type additives slightly thicken the engine lubricant. Due to this, fluidity rates at low temperatures significantly increase. Due to this, the lubricating properties of the oil are significantly increased. Which leads to the possibility of long-term operation in difficult conditions. For example, in city traffic jams. Viscosity also increases at high temperatures.

Typically, such additives include the following components:

• polyisobutylenes;
• polymethacrylates and similar.

Anti-wear coatings cover the working parts of the engine with a special film. Due to this, the friction indicator is reduced, and as a result, engine wear is reduced. Small defects on the cylinder mirrors and in other places are gradually smoothed out.

The use of such additives for crankshaft bearings is especially important. Due to these compositions, it is possible to significantly extend their service life.

Detergent-type additives allow you to restore normal engine operation precisely by naturally removing deposits on the surfaces of parts. The amount of oxides on the surface of the metal and sludge is reduced to a minimum. Anti-corrosion additives also clean parts inside the engine itself. This improves compression and reduces fuel consumption.

The principle of operation of antifriction additives is similar to a conventional engine lubricating composition. Due to the use, it is possible to reduce the friction torque. The composition is added to the base oil directly into the internal combustion engine. The use of these compounds is especially important when the engine is operated in difficult conditions, under significant loads.

What to look for when choosing an additive?

The choice of additive must be made taking into account a large number of different nuances. Please note:

• on the type of composition, the principle of its action;
• what effect does it have?
• manufacturer, consumer product reviews.

The most significant point is precisely the type of composition used. Since the effectiveness of using the additive and the possibility of restoration directly depend on this. For example, if the engine is operated at constant low temperatures, an additive with the effect of removing slag and at the same time increasing the lubricating qualities of the oil is ideal.

The choice in favor of a certain type of additive should be made based on the recommendations of the auto mechanic. There are a large number of methods for diagnosing normal engine operation. This is not only a compression measurement, but also an examination of internal parts using a special video camera. It is on the basis of such data that it is necessary to make a choice in favor of a certain type of composition.

The manufacturer of the specific composition is also an important factor. The success of the recovery procedure directly depends on this. At the moment, there are many brands represented on the Russian market. The choice should be made in favor of the most popular, well-proven one. If possible, you should read reviews in advance of those who have already used a particular product.

The most popular additives for restoring normal engine operation are:

• "Lavr";
• "Suprotek";
• "Hado";
• "Resource";
• "ER".

One of the most popular additives today is “Lavr”. The manufacturer has been present on the Russian market for quite some time. Moreover, it produces various types of additives with directional action. The composition that cleanses the presence of accumulations in the oil drainage channels has shown itself especially well. According to reviews of those using this composition, “Lavr” really significantly increases the service life of a car engine. You can learn more about the main properties on the website https://www.lavr.ru/.

Suprotek produces truly high-quality compounds. According to reviews, it helps a lot in case of problems with valve stem seals. Allows you to equalize compression in all cylinders. Moreover, regardless of the make of the car or its other characteristics. The Suprotek additive allows you to increase the intervals between oil changes.


"Hado" is a company of foreign origin that produces high-quality formulations. All reviews about these additives can be divided into two main categories:

• there is no effect at all;
• The additive coped well with the task assigned to it.

It is only important to remember that in order to obtain the effect of using such an additive, you must strictly follow all the instructions and recommendations of the manufacturer. There is a certain division depending on the mileage of the engine, as well as many different kinds of other factors. It is the failure to follow the basic instructions that explains the lack of effect from using the type of product in question.

"Resource" is a domestic brand. But this does not prevent this composition from performing well when poured into engines of any brand. If the dosage is observed, it can reduce engine oil consumption and increase traction at low and high speeds. It is only important to remember about the increase in viscosity when used in winter, at low temperatures.

“ER” is a special type of additive. There are several varieties. This composition has proven itself best on Subaru cars with boxer engines. The noise during operation is significantly reduced and the service life of the motor is increased. But you should carefully monitor the dosage. Filling is allowed only at a certain mileage.

Conclusion

Engine rebuilding additives really work. But at the same time, you should remember some of their features and application nuances. If you lack experience, you should seek advice from a qualified specialist. This will allow you to avoid a large number of different troubles.

You must purchase goods only from official dealers. Otherwise, you may simply end up with a low-quality product. Not only will it not have a positive effect on the engine, but on the contrary, it can significantly reduce its performance. Or simply “kill” the motor. It is necessary to use additives of any type to restore the engine only after special diagnostics.
