What additives for high mileage engines should you buy?

Oil additives can increase the service life of an old engine, improve driving performance, and reduce oil and fuel consumption. Let's figure out which additives should be used in which cases.

Types of additives

Universal additives and special additives for engines with high mileage can be added to older engines.

The most common types of additives:

• anti-wear;
• restorative;
• detergents;
• eliminating leaks.

LIQUI MOLY Oil-Verlust-Stop

The additive is of the leak-eliminating type. Can be used in gasoline and diesel internal combustion engines. Leaks in rubber elements are eliminated by restoring their elasticity. As a result, the noise from the running motor is reduced. The additive allows you to reduce oil consumption. According to the manufacturer, the additive restores compression. In addition, exhaust toxicity is reduced.

The additive is recommended by the manufacturer for cars with gasoline and diesel engines with a mileage of 100 thousand kilometers or more. Contains the so-called metal conditioner - a set of substances that fill microscopic damage on the surface of engine parts. By minimizing the consequences of wear of parts, compression increases and noise decreases during engine operation.

Car enthusiasts have mixed opinions about the properties of the additive. Many believe that the additive has changed engine performance for the better: throttle response has increased, fuel and oil consumption has decreased. At the same time, the editors of the portal website draw your attention to the fact that the brand is sold only in the CIS countries; nothing is known about the brand abroad. There may be fakes on the market.

Available in 444 ml containers. Cost – 570-610 rubles.

Additive in gel form. The gel contains substances that form a metal-ceramic layer on the surface of worn parts. As a result, the geometry of the parts is significantly aligned. Used in gasoline engines. The manufacturer claims that the additive increases compression overall and equalizes the compression level in different cylinders. Reduces exhaust toxicity levels by up to 8%.

Car enthusiasts who have used the additive note that compression can actually increase. Although the additive, as follows from the reviews, does not eliminate the need for repair work in the future.

The additive is available in 9 ml tubes. Filling into the engine takes place in three stages. After the first fill, a mileage of 100-250 kilometers is required, after the second fill, a similar mileage is needed. One package is required per fill. The cost of packaging is 760-790 rubles.

An automobile additive is a special substance that resembles a lubricant. It is added to engine oil, allowing for many positive effects to be achieved, including fuel economy, increasing engine life, and even repairing a worn-out power plant.

How to choose a high-quality composition and understand the huge range of different products?

Main varieties

To determine the best engine oil additives, first, it’s worth understanding their purpose.

The following types are distinguished:

1. Restoring or anti-friction. Their main task is to restore the internal surfaces of high-mileage engine parts. The additive components fill small cracks in the cylinders, thereby increasing traction and achieving maximum compression. According to the manufacturer, the additive can also help remove carbon deposits and mechanical impurities inside the engine. These products are considered the most versatile. Practical tests show that fuel economy with them is about 5 percent, and torque at medium and low speeds increases. You can really feel all the changes; just press the gas pedal to understand that the car pulls much better.
2. Fuel saving. The set of components is selected so that the composition cleans the parts that form the fuel system from mechanical and chemical contaminants. A decrease in engine power is often caused by dirt, so when faced with it, it’s worth trying an additive. You don't need to use it often, a couple of times a year is enough.
3. Stabilization. They stabilize the oil when operating under critical temperature conditions, restore other used additives, and prevent carbon deposits from forming on the surfaces of the valves and combustion chamber. Visually, the effect of the additive is expressed in the fact that the smoke from the exhaust pipe again becomes colorless, even if before it had a pronounced bluish or black tint. However, if the engine smokes constantly, you should not rely on additives. Only a major overhaul will help here.

Detailed study: gasoline engines

So, restorative compounds are considered the most popular on the market. This is explained by both their versatility and the real ability to extend the life of an old engine and restore some of its minor defects.

Engine restoration additives contain metal dust, carbon or silicon-based components, which act as a “putty” that fills small cracks and scratches, which increases compression.

There are a variety of manufacturers on the market, and therefore we will form a rating based on the results of real research and numerous reviews from drivers. They have been used for quite a long time, and their effectiveness has been confirmed even by leading educational institutions of the Russian Federation, in particular, MSTU. Gorkunov.

So, if we talk about gasoline power plants, the following additives are presented for them:

1. (Suprotec). Not too expensive, but, according to numerous opinions, a really effective additive to the power plant.

Speaking in the language of specialists, this product is not a simple additive, but a full-fledged tribotechnical composition that affects all metal surfaces with which it interacts.

The presence of a metal-clad substance has the effect of cleaning engine parts from plaque and traces of rust, and covers it with a thick layer of protection. An external inspection of the “restored” engine allows us to establish that all small cracks, scratches and other defects disappear, and the service life increases significantly.

Practice shows that the layer formed by the additive, consisting of natural minerals, is really strong. The motor can run completely without oil for an hour without causing any damage.

2. Hado. Performs tasks similar to the previous version, but has a completely different operating principle.

The composition contains granules of a special substance that enter the power plant along with the oil. The components themselves determine which engine parts are damaged the most and stick to them, forming a protective layer of metal-ceramic.

In the case of Suprotek, all working surfaces are uniformly covered, regardless of the current condition.

Tests have shown that this additive gives a good result if the power plant loses pressure. For example, the gaps between the connecting rod journals and the bearings have increased due to wear. Hado corrects this defect.

3. Resource. The manufacturer claims that an innovative composition is used here, which includes silver, tin, copper alloy and certain nanoparticles.

Tests, however, show that one should not expect any special miracles from the Resource. Yes, for the price this is a fairly good product, but nothing more.

4. ER (ER). The composition is highly praised by Japanese enterprises specializing in the sale of used cars. The set of components is kept secret, but practice shows that it is very successful, as it really reduces friction between steel elements.

Increased engine power, increased torque, fuel economy, reduced noise during operation of the power plant - all these effects have also been confirmed. The main point is that adding the additive should be done exclusively when changing the oil; simply pouring it into the engine is pointless.

5. RVS Master Engine. The Finnish manufacturer uses ceramic particles as the main working component. Tests have shown that the additive is suitable not only for automobile gasoline engines, but also for power plants of specialized equipment.

Additionally, magnesium and silicon compounds are used, which form a very thin film on the metal part. The product is quite expensive, but this is compensated by its durability; silicon and magnesium stick to the metal much longer than chromium, tin or copper.

6. Liqui Moly CeraTec. The active component is a complex of elements of organic origin, molybdenum and microscopic particles of ceramics. If the product is used regularly, then we can confidently say that all moving elements are reliably protected from wear.

Reduced friction is achieved due to the fact that microscopic irregularities are perfectly smoothed out. The declared validity period of the additive is 50 thousand kilometers.

Drivers also claim that the positive effects of using this additive are expressed in reducing noise from the operation of the power plant, reducing oil and fuel consumption.

How to protect diesel

Now let's try to find the best additive for an engine running on diesel fuel. The following additives are intended for these motors:

1. Liqui Moly. The German manufacturer uses molybdenum as part of its product; it is interesting that it appeared back in the 40s and successfully passed the test of wartime, being used for the needs of aviation and heavy military equipment. Molybdenum disulfide protects the main components of the vehicle, and it is very stable.

Tests show that this additive is very stable and durable. It does not react with motor oil, does not dissolve in it, forming a durable and strong protective layer on the metal.

2. Resource Diesel. A domestic product that needs to be added when changing the oil and oil filter.

The composition remains stable when used even in engines with a turbine, which eliminates dry friction when starting “cold” or under extreme load. According to the manufacturer, the service life increases by approximately 20 thousand kilometers.

The following positive effects were also noted: compression increases by 40 percent, fuel economy increases by 10 percent. Reviews of the Resource additive for the engine also say that it runs noticeably quieter after it, and starting difficulties disappear, even in the cold season.

3. AC-627 from the Russian brand ASTROhim.

It is added directly to the oil, and the volume of technical fluid already filled can be even 6 liters. The main positive effect is the elimination of gaps formed due to natural wear of elements.

It was possible to establish that the additive actually seals the pistons in the cylinders of diesel power plants. There are no restrictions on the type of oil used with the additive.

Heavy wear

It is also worth studying additives for high mileage engines. It is believed that such a mileage can be called approximately 300 thousand kilometers. However, for regions with harsh climatic conditions or for irresponsible drivers who do not pay enough attention to vehicle care, this value may be less.

Some buyers believe that this type of additive is just an advertising ploy, saying that their composition is completely identical to their standard counterparts. In fact, there is still some difference; the following products have proven themselves best on the market:

• RVS Master. We already drew attention to this additive earlier, but it’s worth repeating, this is a really high-quality and working product. The effectiveness of the combination of magnesium and silicon in restoring damage to an old power plant has been proven; the liquid is compatible with both diesel and gasoline engines;
• Special version of XADO in gel form. A thin protective layer of metal-ceramic is also formed on the surface of the part. Based on the test results, we can say that with the additive, exhaust gases become 8 percent less toxic, and traces of soot, rust and other contaminants are removed from metal elements. To achieve performance from the composition, it is necessary to correctly add it. First, the first portion is poured, the engine travels 250 kilometers, the second portion is filled, and after another 250 kilometers the last batch is added. The additive can not only extend the life of an old engine, but also actually improve its performance. The thickness of the formed metal-ceramic layer is from 0.5 to 0.7 millimeters, which eliminates many gaps that appear during natural wear.

Experience shows that it is not enough just to find a quality product; it is also important to use it correctly in order to realize its full potential.

To do this, the following preparatory procedures are carried out before pouring:

• The motor is washed and the filter elements are changed. To prevent the product from settling on the crankcase, the engine starts in idle mode for about a quarter of an hour after pouring the additive. During this time, the additive is evenly distributed on surfaces and forms a protective layer;
• You cannot change the oil for approximately 2000 kilometers after filling. For the final formation of the protective coating, exactly this mileage is required;
• You can consolidate the positive effect if you pour a portion of the additive approximately 100 kilometers after the first. However, this does not need to be done in all cases, and some manufacturers give personal recommendations on this matter if this application scheme actually works more efficiently than the standard instructions.

Scandals regularly flare up around additives, which is reminiscent of the story with dietary supplements - biologically active additives, which are either recognized as useful or tried to be banned. Let's figure out whether it's worth pouring additives into the engine, or whether it's better to stay away from them.

Additives have a huge impact on engine performance and engine oil change intervals. Due to their special properties, certain chemicals dissolved in motor oil do useful work that extends the life of the engine. Some additives prevent contamination of internal engine surfaces, while others prevent wear, corrosion, or protect parts from exposure to high temperatures and high pressure. What is the reason for a number of scandals that erupted in the late 90s and are still ongoing? What caused the US Federal Trade Commission to charge additive manufacturers? First, let's get acquainted with the theoretical side of the issue. The following is a partial list of substances that are generally recognized to improve the performance of motor oil.

Detergent additives prevent the formation of deposits on vital engine parts. The most common detergent additive is magnesium sulfonate. Antioxidant additives slow down oil degradation. Typical antioxidants are alkylphenols and sulfur-phosphorus-containing substances. Viscosity modifiers prevent base oil viscosity from decreasing at high temperatures. Most often, special polymers are used for this purpose, for example, polymethacrylates. Friction modifiers such as molybdenum compounds help improve fuel economy. Zinc dialkyldithiophosphate and boron are the most well-known substances that reduce wear of mechanical parts. There is no point in listing them all. It is important to understand that all these compounds have been identified over 100 years of scientific development. Their properties have been thoroughly studied. These are the substances that the largest and most respected motor oil manufacturers add to their products. The conflict, as often happens, lies in the area of ​​big business. The thirst for profit leads entrepreneurs to the brink between marketing and deception. In the late 90s - early 2000s, products positioned as engine treatments came to the attention of the US Federal Trade Commission. It was this phrase, which can be translated into Russian as “medicines for the engine,” that attracted the attention of the “American Rospotrebnadzor.” The subsequent series of accusations of dishonest and misleading business practices attracted the interest of the expert community. Motor oil engineers, journalists and enthusiasts have begun to study the composition of products such as Slick 50, Duralube, Motorup or Zmax.

It quickly became clear that the composition of engine oil additives includes the same compounds of zinc, boron and molybdenum that are already contained in engine oil. Experts had a reasonable question: “Why add something to motor oil that is already there”? The Federal Commission's question was phrased slightly differently: "If you are offering 'engine cures,' do you think engines should be treated after using standard motor oil?" As a result of the ensuing litigation in 1997, Blue Corral was prohibited from using the additive manufacturer Slick 50 for marketing purposes to reduce engine wear, improve fuel efficiency and lower operating temperatures. At the request of the Federal Commission, the manufacturer paid more than $20 million in damages to affected customers. The reason for the dispute with the manufacturer of the DuraLube additive was an analytical article in Car&Driver magazine. The publication conducted tests and found that when starved of oil, the piston group of an engine treated with the DuraLube additive seizes only 11 seconds later compared to an engine in which regular motor oil splashes. The Federal Commission prohibited DuraLube from making any of the following marketing claims: the additive reduces engine wear, extends engine life, helps reduce emissions, and reduces the risk of serious damage when oil pressure drops.

More egregious cases are also known. The Federal Commission has proven that the use of Zmax additives leads to a twofold acceleration in the occurrence of corrosion on engine bearings. Three Zmax products actually turned out to be ordinary mineral oil colored with food coloring. The punishment was a campaign to return spent funds to consumers. Another stumbling block for the community has been the deceit of manufacturers who compare the properties of their products with “standard synthetic motor oil” in advertising campaigns. Every major manufacturer has an extensive line of synthetic oils. Different names differ precisely in the packages of additives they contain. For example, Valvoline uses more than a dozen additive packages for just one line of fully synthetic motor oils for passenger cars. This variety is necessary to meet the technical requirements and approvals of various car manufacturers. In addition, some products are designed to solve common problems in worn engines, such as the MaxLife line of oils, which restore the elasticity of oil seals and seals. Such a wide range should in no case and cannot be combined under the general name “standard oil”. More recent scandals are associated with anti-wear additives, which increase the efficiency of the engine lubrication system during startup. Indeed, 90% of engine wear occurs at those moments when the internal surfaces are not yet covered with an oil film that has settled under the influence of gravity during idle time. However, the results of authoritative research show that serious wear begins only if the engine is running under load at the moment of starting. At the same time, 10 to 15 seconds are enough for an oil film to appear on all surfaces, after which the risk of increased wear disappears. Thus, the habit of not starting to drive for just a quarter of a minute extends the life of the engine much more effectively than any additive. Consequently, when purchasing additives that reduce engine wear during startup, the consumer pays for what he already has.

In general, this can be said about all additives, with the exception of those used in extreme conditions, for example, at serious motorsport events. Due to the use of sports gasoline with a high alcohol content, the ingress of incompletely burned alcohol into the engine oil leads to a catastrophic drop in viscosity. To combat this problem, racers use a maximum SAE 60 viscosity grade oil combined with a powerful viscosity modifier. Thus, effective additives from third-party manufacturers still exist. However, a car owner who decides to spend money on their purchase must clearly understand the mechanism of their operation and the goals that he pursues. In most cases, the effect it achieves has nothing to do with the operating mode of the engine of the ordinary passenger car it owns. Thoughtless spending of money on additives (as well as on dietary supplements) leads to the enrichment of owners of brands that produce dubious products, and nothing more. Separately, it should be noted the legal issue of using additional additives during the warranty period of vehicle operation. Most car manufacturers explicitly prohibit this in their owner's manuals. The fact of using an additional additive is easily proven. Laboratory analysis of the sample taken will show a discrepancy with the original elemental composition of the oil. Therefore, warranty repairs of a failed engine can be challenged by the automaker's representative office on the basis of non-compliance with warranty obligations.

To improve the performance and service life of a car engine, engine additives are used, the best of which can be selected based on their advantages and features of use. An oil additive is not a universal way to increase the service life of machine parts - however, its use is a good preventive measure even for a relatively new engine. True, when choosing a suitable option, you should pay attention to its specialization - each additive has its own purpose, and many of them are suitable only for diesel or, conversely, gasoline cars.

The best additives for gasoline engines

Additives for vehicles that run on gasoline should be changed every 2-10 thousand kilometers. They are divided into two categories:

• additives for carburetor engines;
• additives for injection power units.

The latter must have binding properties and allow you to get rid of water trapped in gasoline. Additives for carburetor engines also provide protection against icing.

Liqui Moly CeraTec

The CeraTec additive, which contains microceramic particles and a molybdenum-organic complex, is designed to improve the performance of gasoline power units. Among the capabilities of the additive is the smoothing of micro-irregularities on the internal surfaces of the motor, which significantly reduces friction and increases the life of the motor. The film lasts up to 50 thousand km, after which it is recommended to use the additive again.

• noticeable reduction in gasoline consumption;
• savings on lubrication;
• long duration of action;
• reducing the volume of the power unit.

• High price.

Liqui Moly Speed ​​Tec

The Speed ​​Tec additive is used to improve the performance of two- and four-stroke gasoline engines. The additive contains no metal particles, which makes it safe for the engine, regardless of operating conditions. The product acts quickly, increases the efficiency of fuel combustion, and one can is enough for 70 liters of gasoline.

• absence of organometallic compounds, which is why Speed ​​Tec can be considered safe at any engine load;
• higher power and improved engine performance;
• cleaning the exhaust system.

• Low efficiency when used together with high-quality fuel - for example, AI-95 or AI-98.

The additive performs best when used with average quality gasoline.

Lucas Oil 10131

The main task of the Lucas additive is to improve lubrication parameters for gasoline engines. The product prevents dry starting and provides protection for any modern engine, including the most powerful ones designed for car racing. The additive can withstand extreme operating conditions, and it should be changed no more often than after 20,000 km.

• high quality manufacturing, despite the fact that the stabilizer is produced in the USA and meets all the fairly strict requirements of this country;
• effective elimination of vibration and noise of a car engine;
• power unit temperature control.

• High price;
• Rarely found not only in regular retail outlets, but even in online stores.
• It negatively affects the quality of the oil, which has to be changed more often.

Hi-Gear SMT2

To increase the service life of a gasoline engine, you can also use the Hi-Gear SMT2 additive. The additive includes a special air conditioner that reduces dynamic loads on the power unit. Tests have shown that the engine lasts at least 2 times longer.

• the use in the manufacture of the additive of a special high-tech formula that prevents oxidation and the release of gases from the combustion chamber into the crankcase;
• improving the anti-scuff and viscosity properties of oils, reducing their “burn”;
• fuel economy;
• reducing the sound of valves and acoustic noise from the engine;
• increasing the service life of a worn-out power unit by 1.5-2.5 times;
• Compatible with gasoline engines of any generation and type.

• Relatively short duration of action of the additive.

The best additives for diesel engines

For cars running on diesel fuel, additives are needed no less than for gasoline vehicles. This is especially true for cars that have been in operation for several years - a large amount of soot has already formed in their exhaust system, and fuel consumption has noticeably increased. Special additives allow you to optimize engine performance, improve fuel parameters and reduce fuel consumption.

ER

A product popular for improving the engine performance of Japanese diesel cars. Thanks to the effectiveness of this additive, the friction of steel parts is reduced, engine power increases, less fuel is consumed than without using ER, and the period between oil fills becomes longer. According to many motorists, the additive is becoming a real salvation for the power units of old cars.

• a noticeable increase in torque and performance of the power unit;
• reducing diesel fuel and lubricant consumption;
• affordable cost, which makes the additive an excellent option for owners of old cars.

• Incompatibility of the product with a number of motor oils - if the additive is used together with them, a dense film is formed on the surface of the engine, which can only be removed by thorough washing.

Castrol TDA

Suitable for engines that run on diesel fuel. With its help, the corrosion process slows down and the negative impact of fuel components on fuel system parts is reduced. And this product, suitable for any season, will be most effective when used in winter.

• the ability to optimize the process of starting the power unit at any time of the year - although the effectiveness of the additive increases in winter;
• no effect on fuel viscosity and increase in its lubricating properties;
• reduction of noise and soot formation from a car engine.

• Less effective when using the additive in the warm season;
• As the dosage increases, the risk of rapid contamination of the fuel filter increases. To solve this problem, filter elements have to be changed several times more often.

Bardahl Full Metal

It is considered one of the most popular means for restoring the operation of a diesel engine on the Russian market. The reasons for the demand are Polar Plus technology, which increases adhesive properties and protects the motor during cold starts. The additive reduces friction and, as a result, saves fuel and lubrication, reduces emissions in exhaust gases - and it can be used as a restorative or preventive additive.

• restoration of tightness in the contact area of ​​the cylinder wall and the piston;
• reduction of deposits that impair engine performance;
• reduction of friction forces, which saves fuel;
• increasing the power of a worn-out power unit;
• reducing emissions of harmful substances into the atmosphere.

• High price;
• It is not often found even in online stores with a wide assortment.

Hi-Gear Diesel Antigel

The American-made product provides improved diesel fuel performance without a noticeable increase in costs. By adding an additive to summer grades of fuel, you can increase their pour point to -27 degrees, and to -51 degrees for winter grades. The effectiveness of the product has been tested and confirmed by specialists from different countries, including Russian automotive experts.

• effective reduction of fuel filterability level and gelation temperature;
• safety during use - the dispersant additive does not lead to engine failure even under extreme engine operating conditions;
• affordable price compared to products of other brands - depending on the concentration, from 1 to 3 rubles are spent on processing 1 liter of fuel;
• absence of fakes on the market.

• The can's ill-conceived dosing system.
• There is a strong change in properties after the expiration date, so it is recommended to use the product only within the period specified by the manufacturer.

Best all-around options

Universal additives are usually called products that improve several characteristics at once - for example, increase engine efficiency and clean valves. The same term can be used to describe additives intended for use in both diesel and gasoline engines.

FENOM FN 710

Purchasing an organometallic additive for motor oils FENOM FN 710 provides good engine protection against wear and restores its performance characteristics. The product is suitable for gasoline and diesel engines, restoring microdefects on their surface and increasing the wear resistance of individual parts. Fuel and lubricant consumption is reduced, and compression in the internal combustion engine cylinders is equalized.

• maximum efficiency of cleaning the internal surfaces of the engine and fuel system;
• increasing the stability of the engine and the wear resistance of its parts;
• good cooling of the power unit, increasing its resource.

• High price.

Oil Additive Liqui Moly

Contains molybdenum disulfide and is the best option for power units of older cars - both those that run on gasoline and diesel. The product is compatible with any motor oils - from mineral to synthetic. It should be changed every 30-50 thousand km, depending on the operating conditions of the vehicle.

• maintaining stability, regardless of the level of dynamic and thermal load;
• no formation of deposits and no influence of the additive on fuel filters;
• reduction in wear of the power unit, especially noticeable for cars with high mileage;
• preventing engine damage even in extreme circumstances (oil leakage or overheating);
• reduction of fuel and lubricant consumption.

• The composition of the additive, which contains enough molybdenum, leads to the presence of certain disadvantages. First of all, this concerns engine operation at high speeds - under such conditions, molybdenum particles penetrate the piston rings, leading to their rapid wear. Although other engine parts wear out much less when using Oil Additiv.

RedLine Engine Oil Break-In Additive

It is not just an additive, but a set of additives designed to reduce wear on gasoline and diesel engines. It contains zinc and phosphorus, which have a beneficial effect on valve mechanisms and camshafts. Such additives are used to improve the characteristics of mineral and synthetic oils, and they should be added to the oil every 6,000 km.

• ensuring proper lapping of piston rings;
• protection of engine parts from wear;
• large package, which is enough for 11.5 liters of oil or 1.5-2 refills;
• special formula that reduces friction;
• reduction of fuel detonation.

• High price;
• The oil in an engine to which such a product is added will have to be changed much more often.

Sea Foam SF 16

It is a universal product suitable for improving the performance of fuel and oil. It is suitable for almost all 2 and 4 stroke gasoline engines and some diesel units. Provides compression restoration, cleaning of the engine intake, injectors and intake valves, lubrication and fuel systems, and it is recommended to change it every 5000-8000 km.

• safety for power unit parts, gaskets and seals, gauges and sensors;
• compatibility with any brands of gasoline and diesel fuel, mineral and synthetic oils;
• Compatible with most 2 and 4 stroke engines.

• Rarely found in places of sale.
• Possible fakes.

Best Sealing Additives

Additives for sealing are often called “stop leaks”, since with their help the car owner not only eliminates existing leaks, but also reduces the likelihood of new ones. However, when choosing such a tool, several nuances should be taken into account:

• it should be used immediately after detecting a leak - if a lot of time has passed, the sealing additive may not help;
• if severe cracks appear, the additive also does not help - the problem can only be solved by replacing the worn oil seal or gasket;
• If the car owner finds a large amount of sludge deposits in the engine, it is recommended to flush the engine before using the additive.

On the other hand, the effectiveness of such funds is quite high. Most of them help to reduce the frequency of repairs of the power unit and fuel system several times.
