Engine additives: should they be poured into the engine? The best additives for the engine. We understand the range of products The most effective oil additives
The owner of a vehicle will never spare money when purchasing high-quality parts and auto chemical goods. Some motorists are even ready to give up purchasing new clothes for themselves, various goodies, just to save a certain amount, allowing them to purchase something for their favorite car. In principle, there is nothing surprising in this attitude towards the vehicle. We recommend paying attention to the additive added to the oil for high mileage engines. Experienced specialists confirm the effectiveness of using such auto chemicals, but only subject to full compliance with all technical recommendations.
Qualitative characteristics of additives
Many motorists who have already seen from their own experience the effectiveness of using automobiles confirm that they really work, allowing even an old engine to work smoothly and without problems. But not all motorists can experience this result; some have to pay bitterly for conducting experiments. It is not without reason that the opinions of motorists regarding the rationality of using additives are divided. Some actively praise them, while others, on the contrary, strongly discourage their use. There are many negative reviews, but in most cases it is not a specific product that is to blame, but the incorrect behavior of the car owner, who hastened to add auto chemicals without reading the instructions and without studying the manufacturer’s recommendations.
When to use
Let's compare the additive with tablets. You will not use medications unnecessarily, even if everyone around you praises them and convinces them of their incredible effectiveness and excellent healing effect. The same should be done with auto chemical goods; use additives, adding them to an engine with high mileage, only when the need arises. Experienced drivers consider auto chemicals, which are poured into oil for a diesel or gasoline engine, as a lifeline. If you begin to notice that your engine is not in order, you will only have a few options, from which you will have to choose the most suitable one:
- carry out expensive repairs of the internal combustion engine;
- purchase a new internal combustion engine (we note right away that buying a used engine is not recommended, since you can buy a “pig in a poke”; after installation on your car, it may turn out that it is also in poor condition);
- add the additive to the engine oil.
The most affordable option of the three listed is the introduction of a “miracle cure”. In addition, you can get instant results, whereas repairs are not carried out in one day, nor is installing a new engine. A high-quality additive can revive the engine and allow the car owner to continue using the vehicle for some time, during which the motorist will have time to accumulate the required amount for repair work.
Types of additives for high mileage engines
Currently available for purchase:
- anti-wear;
- restorative;
- detergents;
- eliminating leaks.
In addition, there are options designed not only for the engine, but also to improve the performance of the fuel system and gearbox. Do not forget to notify the sales establishment employee about what fuel you use and what motor oil is already poured into the engine of your vehicle. Having complete information allows you to select the best additive and verify its effectiveness in practice.
Anti-wear additives significantly reduce friction. During testing, experts calculated that the friction of parts is reduced by 25%; accordingly, the wear of all components of the engine is reduced, extending its “life” for a long time.
Restoration options are actively used by owners of used cars who want to sell their vehicle at a higher price and, in order to do this, hide existing shortcomings. By introducing restorative additives into engine oil, it is possible to revive damaged components of the unit, as a result of which the compression in the piston group increases, allowing the vehicle to continue to be used for some time, eliminating the urgent need for major repairs.
Detergent additives are also popular among motorists. If you use such auto chemicals, the engine will always be clean, no deposits will interfere with its flawless operation. Immediately after being introduced into the engine oil, the additive begins to dissolve carbon deposits, as well as deposits that appear on the surface of the components of the unit. Detergent additives are especially recommended for use if the car has a high mileage.
Additives have unique properties, including the ability to eliminate minor defects. In particular, when scratches and microcracks occur, engine oil begins to slowly leak out. A deficiency negatively affects the operation of the engine; if a significant deficiency occurs, it can even cause engine failure. To prevent such sad consequences, accompanied by significant financial costs, many motorists decide to use additives that eliminate leaks.
Also popular are options such as energy-saving ones, which allow saving fuel consumption by at least 20%, as well as dehydrogenating additives, which prevent the formation of condensation in the fuel system and the subsequent destructive effects of moisture.
Features of application
If your vehicle has a diesel engine, the recommendations that are actively used by owners of gasoline cars are clearly not suitable for you. In a car shop, specialists can offer several options for additives that will be suitable for different types of engines, however, there are few such examples. All other additives are aimed at a specific type of internal combustion engine.
By adding additives to diesel fuel, its quality characteristics can be significantly improved. Unfortunately, it is difficult to find the highest quality fuel at our gas stations. Diesel additives help reduce carbon deposits in the cylinders. By pouring such additives into gasoline, it is possible to significantly increase the fuel's resistance to detonation. Reasonable introduction of additives into engine oil will not go unnoticed, engine performance will improve.
The best offers on the market
Currently, there are a sufficient number of different additives that are poured into the engine; which one is best for your car is up to you to decide, taking into account the problems that influenced such a decision. Here are the characteristics of some of the most popular additives, which will allow you to make the right choice.
RVS Master additives of Finnish origin are rightfully considered one of the best. They are designed for both diesel and gasoline engines. What’s impressive is that RVS Master additives have a long-lasting effect. They are capable of having a positive effect on the operation of a car engine, covering a distance of up to 120 thousand kilometers after adding auto chemicals. The additive contains silicon and magnesium. The combination of these two substances promotes the formation of a thin layer on the surface of the engine, which performs protective as well as restorative functions. Thanks to these characteristics, the engine resource increases.
XADO additives are sold in gel form. When such an additive is introduced, a protective metal-ceramic layer is formed on the surface of the unit. The additive manufacturer assures that the use of such auto chemicals increases compression, increases engine life, and also reduces the level of exhaust gas toxicity by 8%. The additive also has cleaning properties. Its introduction is carried out in three stages. Initially, the additive is poured in, after which you need to drive the car for about 250 kilometers, then the additive is poured in again, and the car is used again, finally the additive is introduced a third time. Only such a triple introduction of the XADO additive will ensure maximum efficiency of its use.
"Suprotek" is a restoring tribocomposition (according to the manufacturer), which has a positive effect on metal structures. Thanks to the following:
- excellent cleaning of the engine from plaque;
- removing rust;
- prevention of corrosion;
- providing a protective layer;
- elimination of minor defects (scratches, cracks and chips).
The Suprotek additive provides a significant reduction in friction force, which helps prevent premature wear of the components of the unit. By the way, the tests carried out demonstrated that the vehicle is capable of successfully operating for several hours on only one additive, even if no oil is poured into the engine at all. All these amazing characteristics of the additive ensure a high level of popularity of this auto chemical product.
“Liqui Moly” is an additive from a German manufacturer that is particularly popular. It contains magnesium and calcium, and the base consists of liquid ceramics. Also, “Liqui Moly” contains the best additive – which provides a significant reduction in friction force. The positive effect of the additive has been confirmed by its long-term use. Vehicle owners have been actively using the additive for eight decades, confirming:
- reduction of wear of parts;
- reduction in fuel consumption;
- improving engine performance.
The only problem when purchasing this additive may be its high cost. However, such a high price is justified by the amazing composition and incredible effectiveness of the additive.
We recommend approaching the issue of purchasing auto chemical products with maximum responsibility. Do not buy additives containing minerals. They can clog the oil system and cause unpleasant consequences. Study the characteristics of the additive that has piqued your interest, consult with experienced motorists, and only then purchase and add the product, increasing the performance of your vehicle.
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 begin to be used if 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.
Viscous-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 directional additives. 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 manufacturer’s instructions and recommendations. 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 most well 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.
The issue of using additional additives in motor oil has long divided the audience of car owners into two irreconcilable camps. Those discussing with “officials”, in most cases, take the official position of oil producers, which states that the finished oil already contains everything that is needed for normal operation of the equipment. Those who use multi-brand services, or service equipment in garages, allow or recommend additional additives. Let's figure out whether additives in motor oil are harmful?
Additional additives are added when the car owner wants to solve either individual problems that arise during operation, or when he wants to protect the engine and increase its service life.
Independent assessments indicate that conditions in Russia are dire. The main thing is that our climate, daily and seasonal temperature fluctuations, dirt in the air and on the roads, operating conditions, fuel quality and the average age of the vehicle fleet are not the best conditions for increasing engine life. For comparison, the average age of a car in Germany is nine years, and in Russia it is seventeen, that is, almost twice as old. Of course, the engine life will be completely different. But even in Europe they use additives in motor oils. In Italy and Greece, additives are more popular than in Finland or England. Germany, as a country with a well-developed automotive and chemical industry, has the largest number of manufacturers of additional additives. And car owners in Germany also use additives.
Additives solve certain operational issues, such as: wear, oil leaks, oil smoke and waste, decreased compression, noise, pollution. That is, all the issues that the package of active substances added during the production of commercial oil is intended to solve.
Most additives are similar substances that are used in the production of commercial oil, only in higher concentrations.
When developing a certain type of motor oil, the manufacturer decides many issues, and one of the main ones is the cost of the finished product. Additives are the most expensive components; manufacturers calculate their concentration so that the oil meets normal operating conditions. And if operation is not normal, then the additive components begin to quickly deplete, reducing the oil’s service life. And a decrease in oil life is fraught with a decrease in engine life. Frequent oil changes are an expensive undertaking, and not only because of the cost of the oil itself. Manual labor and time to plan the procedure are required. That is, frequent replacements are not beneficial to the car owner, and this is where additional additives come to the rescue.
How can additives help an engine?
The first and most common problem. Around the middle of the service interval the oil thins out, this is a natural process, but it can lead to a loss of pressure in the oil line and increased oil consumption. During operation, the oil thins out due to the destruction of the polymer thickener and the oil begins to lose viscosity. To restore viscosity characteristics, the car owner can use the Liqui Moly Visco Stabil thickener additive. The use of the additive will increase the oil viscosity, increase the pressure in the system and reduce oil waste. Thereby preventing premature wear due to low oil pressure.
Problem two. No matter how much you improve a standard oil, it anti-wear properties will be insufficient. Especially for modern engines, which have reduced internal friction to achieve greater fuel economy. Reducing friction is achieved by reducing the area of friction surfaces, as a result of which the load on them seriously increases. Modern engines no longer have a million-dollar lifespan, like their ancestors from the 90s. The way out is to use additional anti-friction additives, such as. The additive in combination protects the engine from wear, facilitates the movement of parts, reduces operating noise and fuel consumption, in total this allows to increase the engine life. The secret is microceramic boron nitride particles, which are the slipperiest substance on Earth. Cera Tec can be used with any motor oils; microceramics does not chemically interact in any way with the standard additive package. You can select an antifriction additive for a specific case. Or seek advice on the company forum.
A common problem is oil leaks and him high consumption. Flow is built into many modern engines. But consumption of more than a liter per 1000 km is a reason to think about it. In most cases of increased oil consumption, the engine designer is to blame. To obtain more power, the engine's operating process is made increasingly “hotter”. As a result of constantly elevated temperatures, the valve stem seals “dry” and begin to leak oil into the combustion chambers. The result is high oil consumption without characteristic smoke, since the catalyst copes with smoke quite successfully. At some point, this can lead to oil starvation, which will negatively affect engine life. Liqui Moly will help restore gaskets, oil seals and valve stem seals to working condition. As an active component, this additive contains esters (essential oils), which not only restore rubber, but also increase the stickiness of the oil film. That is, by using this additive, the consumer reduces oil consumption and further reduces engine wear.
Engine contamination. As a rule, even if the operating instructions are followed, contaminants accumulate in the engine after 40-50 thousand kilometers. If nothing is done, the contamination progresses, which leads to increased wear as a result of poor oil circulation and coking of the rings with loss of compression. Numerous online publications are devoted to this topic, but the main solution to the problem is the regular use of oil flush additives. Flushing additives can be quick, effective for 5-10 minutes, and long-term, designed for 150-300 km, the latter being the most effective. How it works? Flushing consists of the same detergent components that are used in motor oils, but in much higher concentrations. In addition, solvents are used to thin the oil and improve its circulation in thin gaps. Naphthenic oils, which have excellent cleaning properties, are often used instead of solvents in long-term washes. Proper flushing does not tear off large particles of contaminants, but gently and layer by layer transfers contaminants into a dissolved state, allowing them to leave the engine during the process of draining the old oil. Also, the washes, like motor oil, necessarily contain anti-seize components that protect the engine during the wash process. Flushing restores the performance of the oil system, reduces wear, releases stuck rings, eliminates smoking and maintains the performance of engine hydraulic mechanisms, such as hydraulic compensators, hydraulic tensioners and VTEC or VVTi type variable-phase clutches. Flushing additives are almost completely drained from the engine when the oil is changed and do not affect the properties of fresh oil, unlike the so-called “flushing” oil. The use of flushes can significantly increase engine life. Select a detergent additive. depending on the case is possible . Or seek advice on the company forum.
One more problem - noisy operation of hydraulic compensators. Increased noise during operation of the gas distribution mechanism is a sign of a malfunction, which in the future can develop into expensive repairs. To normalize the operation of hydraulic compensators, a special additive is used - Liqui Moly. This additive normalizes the operation of all engine hydraulics and eliminates operating noise. Its mechanism of action is to eliminate contaminants in oil channels and increase the durability of the oil film due to polymer components. Thus increasing the reliability of the gas distribution mechanism.
We have looked at the main cases of using additives in motor oil, but certainly not all possible options. Now, knowing the composition and effect of additives, you yourself can conclude whether additives in motor oil are harmful.
To extend engine life and improve its performance, many motorists use special additives. You can often hear negative reviews and opinions about the dangers of such additives and arguments that excess chemicals will only harm the unit. But in fact, if you use good quality products from trusted manufacturers, the consequences will be only positive. According to the method of application, they can be divided into those added to fuel, to the engine or to the gearbox. The rating of engine additives according to the Mark.guru portal presents the best options in each of these categories.
To choose the right additive for your car, you need to understand the following points:
- Purpose. Fuel tank additives can be fuel-saving or dehydrating. The latter are designed to improve engine starting in cold weather. Products added to engine oil are intended for engine restoration or restoration. In the first case, cleansing occurs, as well as restoration of small cracks. Reducing additives are also often called anti-smoke additives; they reduce the amount of carbon deposits, increasing the viscosity of the oil. It should be noted that they do not solve the problem of unit wear.
- Compound. The chemical basis of the additive affects its properties. The most popular ones contain mineral powder as a base; it allows you to grind the surface of engine parts. The metal-clad base allows the compound to penetrate into areas of friction and smooth out defects caused by wear. Polyester and chlorinated paraffin additives act as a cleaning agent that removes dirt and carbon deposits.
- Fuel type. There are products for diesel and gasoline engines.
- Manufacturer. Engine repair is one of the most expensive types of work, so choose additives only from well-established manufacturers in trusted stores. Fake or low-quality products can lead not only to deterioration of performance, but also to failure of the unit.

Conclusion
The best engine additives presented in the rating will significantly improve the performance properties of the car. Thanks to them, the mechanisms will last longer; in addition, some products allow you to save gas or oil consumption. They themselves, of course, are also not cheap. But repairing the engine and gearbox, especially automatic ones, is usually very expensive. The need and advisability of using additives is decided on a case-by-case basis, taking into account the degree of wear and existing faults. Remember that additives are not a means of repair, but only improve performance for a while.
Greetings! The internal combustion engine is rightfully considered the main element in the design of any car, and you, dear friends, are sure to have heard this more than once. This applies to a greater extent to our cars, which quite often present surprises in the form of various breakdowns of the power unit. If you have owned a domestic car for long enough, you have probably had to “prick” the engine more than once or twice. No, I understand that for an experienced person, any engine repair (even the most terrible) is a matter of time. However, for most, this problem is complex and difficult to overcome.
And it seems that thanks to modern technologies, there are already special compounds on sale that protect the power unit from malfunction, but the attitude of drivers towards them is ambiguous. We are talking about additives that have been available on the market for about 10 years now. We Russians take a long time to get used to new things, so even today some car enthusiasts do not risk experimenting. Others, on the contrary, use a new product, which is already ridiculous to call a new product, to the fullest. Today, your humble servant has a clear intention - to describe to you the best additives for the engine. And convince all non-believers that they are really effective!
Engine additives - definition, types and principle of operation
Fluids designed to increase the service life of the engine and gearbox are called additives. In the wide range of each manufacturer there is a place for similar products for diesel and gasoline engines. In order for the additive to begin to perform its direct functions, the car owner just needs to add it to the oil of the power unit or gearbox. However, gasoline additives are no less popular; they can not only clean the engine of harmful elements, but also increase the octane number of the fuel, dry it, and so on.
Engine additives, depending on their functions, are divided into the following types:
- Conservation;
- Viscosity changing oils - useful in both cold and hot weather;
- Anti-corrosion;
- Compression additive;
- Detergents are the best solution for cleaning the power unit from carbon deposits and other contaminants;
- Antifriction;
- Protective - protect the motor from the appearance of various “scuffs”.
This type of liquid acts as follows: when it gets into the oil, the additive forms a film on the friction pairs, due to which pressure and compression increase for a while and even reduce the consumption of the same oil and fuel. However, here we must pay tribute to the pessimists; there is some truth in their words. The fact is that a budget product, like a more expensive one, will give a positive effect, but over time, due to the chlorine and paraffin content in their composition, they can lead to clogging of the oil channels. Therefore, I draw your attention to the fact that engine additives are not something you should skimp on. Don't worry, I'll tell you more about really high-quality products!
Some more varieties
That is, you understand, yes, a high-quality additive reduces friction, thereby increasing productivity. In addition, this is an ideal option for an engine after a major overhaul, because this composition improves the grinding in of engine parts. For engines with high mileage, the additive will also come in handy; it will not only restore the cermet layer, but also clean important engine elements from tarry deposits.
Of course, a similar effect is achieved due to the chemical composition; according to this criterion, all additives are divided into three types:
- Based on mineral powders, the surface of the parts is polished, after which a metal-ceramic layer is created.
- Based on active chlorinated paraffin and polyesters, it is probably the least popular product, but it also has its advantages. In an environment of high temperatures and pressure, such a composition can act like a regular flushing oil. It converts all deposits (dirt, carbon deposits, etc.) on parts into an ionic state, due to which all contaminants leave the engine along with the oil when it is drained.
- Based on metal-clad compositions - when liquid penetrates into the friction area, where there are defects due to excessive wear of the crankshaft and piston group bearings, it completely levels them due to the formation of a cladding layer.
When planning to buy an engine additive, it is extremely important to understand what you want to achieve from it: break in a rebuilt engine, extend the life of an old one, or simply increase its performance. Your choice should also be influenced by the type of engine you have and the oil poured into it. Please note: different additives are used for semi-synthetic, synthetic and mineral oils; incorrect selection may deprive you of the expected effect. By taking the above factors into account, you significantly increase the likelihood of purchasing a product that is relevant for your motor!
When is using an additive the only option?
An additive for engine restoration is like throwing an inflatable ring to a drowning engine, the life of which is running out. You know, replacing or repairing a power unit will definitely cost its owner a pretty penny, and the use of new technologies will extend the life of the “heart of the car.” I agree, not for long, but several thousand additional kilometers are worth the cost of such a chemical additive.
As an example, I’ll tell you my story from the past. For some time, the engine of my Zhiguli car made it clear to me that it did not have long to live. The compression dropped noticeably, I filled in a lot of oil, almost on par with fuel. It's funny to you, but it wasn't very funny to me at the time. So one experienced comrade, having assessed the situation, tells me: “Friend, you only have three options.” This is what he offered me:
- Major repairs - I immediately rejected neither the money nor the desire to tinker with the car for days.
- Purchasing specialized and therefore expensive oil for engines with high mileage - having learned its cost, this option was rejected.
- I chose cheap oil in tandem with additives without hesitation, and I had nothing to lose.
To be honest, I didn’t expect any special results; experienced people know that with such symptoms, the days before engine repair are numbered. But thank God I was wrong! Without noticing it, I began to add oil much less frequently and turn the steering wheel much more often. However, the saddest thing is that the effect of the supplement is short-lived; after a couple of months everything returned to normal. And the most annoying thing is that repeated use of additives did not give any results.
The conclusion from this is that the additive can help the power unit in “difficult times,” but this effect is not endless. And again, this is a “coin” with two sides: if everything is fine with your engine, you should not resort to various additives, because just like restoration, they can do harm! I hope everything is clear with the advantages and disadvantages of the described compositions; then you will find out which additives have proven themselves exclusively on the positive side.
The best additives sold in Russia
In our country you can find a variety of brands that specialize in the production of engine additives. I analyzed the market and selected the best ones for you! They are for your attention!
Xado
A domestic brand with more than 20 years of history has won both its supporters and critics. The latter focus on the high cost of Xado formulations, so one tube with a capacity of 10 ml will cost you at least 300 rubles. The manufacturer insists that in order to completely restore the power unit, it is necessary to carry out a full course of a similar procedure, which includes five such repetitions. Thus, to achieve the desired effect, you will need 1,500 rubles and more.
However, there are much more advantages; it is thanks to them that the product is popular not only in the Russian Federation, but also far beyond its borders. The Hadot additive is a completely safe product; it still needs to manage to harm the engine, although based on reviews, this possibility is almost completely excluded. The quality of operation is at the same high level - the engine will operate stably after 200 and 300 kilometers traveled by the car.
Suprotec
The same reviews from the majority speak of the high quality of Suprotek additives. This manufacturer produces additives for engines, gearboxes and even gearboxes (be careful when choosing). And the best part is that the product, like the one described above, is completely safe and, most importantly, effective!
Users note a significant reduction in fuel consumption (10-15%) for units intended for filling into a gas tank. As for restorative compounds, they are also good. Increasing compression in the engine, as well as closing all microcracks, are only part of the positive qualities. And the most important thing for the consumer is price. Compared to the same Hado, it is half the price. So, a 90-ml tube will again cost you 1,500 rubles.
Liqvi Moly
And of course, our mini-rating could not do without a representative from Germany. It doesn’t matter at all whether you have a diesel car or a gasoline car in the range of the German brand Liqui Moly, there are additives for all types of engines. The product of this brand is positioned as universal. That is, with its help you can not only reduce overall fuel consumption, but also restore the metal surfaces of the cylinder-piston group of the power unit. In addition, the cost of the additive is the most affordable - 400 rubles.
In my personal opinion, choosing an additive is one of those cases when you should not give preference to a domestic manufacturer! Well, why overpay when you can save money without losing the quality of the product. What you choose is again up to you to decide! Before we say goodbye, I assure you once again: you should not believe the critics, many international studies have proven that additives from the world's leading manufacturers really correspond to the properties declared by the manufacturer! Appreciate the power unit of your car, and it will reciprocate! All the best and don’t forget about the video I prepared for you!
