Anti-smoke - an additive to prevent the internal combustion engine from smoking
Content
What to pour into the internal combustion engine so that it does not smoke? This question is often asked by car owners when selling a car. And they, the same deals, are offered to deceive the buyer with the help of the Antismoke additive. The problem with the motor can be hidden even during the daily operation of the car, hoping that not only the symptom will disappear, but the cause itself. Although this is not at all the case, this remedy removes the symptom for a short time, but does not cure!
Additive for internal combustion engines antismoke allows you to temporarily get rid of a significant amount of exhaust gases, as well as strong noise that occurs during the operation of internal combustion engines. However, such funds are not repair, but rather "camouflage", which is often used when selling used cars. If we are talking about a real repair of a car that smokes a lot, then you first need to measure the compression of the internal combustion engine and use the means for decoking. Further work depends on the state of the internal combustion engine.
As for the so-called anti-smoke in oil, at present on the shelves of car dealerships you can find similar products from many popular manufacturers, for example, Liqui Moly, Xado, Hi-Gear, Mannol, Kerry and others. On the Internet you can find a lot of conflicting reviews about certain means. And it depends on two factors. The first is the presence of fakes on sale, the second is a different degree of "neglect" of the internal combustion engine. However, if you have had a positive or negative experience with any anti-smoke products, please write about it in the comments. This will add objectivity to this rating.

Reasons for the increase in ICE smoke
Before turning to a review of the characteristics and effectiveness of specific products, let's briefly dwell on the mechanism of operation of smoke additives, since most of them are very similar, both in composition and in their effect on internal combustion engines. But in order to correctly choose an additive that would help against smoke, you need to find out why thick black or blue smoke can come out of a car exhaust pipe. So, the cause of significant smoke can be:
- Wear of elements of the cylinder-piston group of internal combustion engines. namely, we are talking about breaking through the cylinder head gasket, wear of the oil scraper rings, changing the geometry of the cylinders and other breakdowns due to which the oil enters the combustion chambers and is burned along with the fuel. Because of this, the exhaust gases become dark, and their amount increases.
- ICE aging. At the same time, gaps and backlashes between individual elements of the CPG and other systems increase. This can also lead to a situation where the engine will "eat up" oil, and similarly there will be a large amount of black (or blue) exhaust gases.
- Incorrect selection of engine oil. namely, if it is very thick and/or old.
- Oil seal leak. Because of this, oil can also enter the combustion chamber or simply on the hot elements of the engine and fry. However, in this case, the smoke will most likely come from the engine compartment.
usually, an increase in the amount of exhaust gases (for both gasoline and diesel ICEs) occurs with old and / or very worn ICEs (with high mileage). Therefore, with the help of additives, you can only temporarily “disguise” the breakdown, but not get rid of it.
How smoke additives work
In a nutshell, we can say that anti-smoke additives are the so-called oil thickeners. That is, they increase the viscosity of the lubricant, due to which a smaller amount of it enters the piston and, there, burns out. However, a small amount of lubricant in the internal combustion engine and its insufficient flow leads to serious (and sometimes critical) wear of individual parts and the internal combustion engine as a whole. In such conditions, it works “for wear”, at elevated temperatures and almost “dry”. Naturally, this sharply reduces its overall resource. Therefore, the use of such an additive can not only remove the symptom, but completely disable the motor.
Most anti-smoke additives work on the same principle, have a similar composition, regardless of the manufacturer and / or brand under which they are released. So, they often include molybdenum disulfide, ceramic microparticles, detergent compounds (surfactants, surfactants) and other chemical compounds. Thanks to such elements, it is possible to solve the following three tasks that the additives face:
- the creation of a polymer protective film on the surface of the machined parts of the internal combustion engine, thereby extending the life of both parts, namely, and the motor as a whole;
- filling with the composition of small damages, shells, wear, and thereby restoring the normal geometry of internal combustion engine parts, which leads to a decrease in backlash, and as a result, smoke;
- purification of oil and the surface of internal combustion engine parts from various contaminants (cleaning properties).
Many manufacturers of anti-smoke additives claim that their products are able to save fuel, restore (increase) compression, and also increase the overall life of the internal combustion engine. However, in reality most of them do not significantly affect the operation of the motor, and only with the help of chemical compounds present in their composition, they neutralize excessive smoke in worn motors. Therefore, one should not expect a miracle from the additive, which consists in the restoration of the internal combustion engine, and even more so for a long-term effect (in 100% of cases, the effect of the additive will be only short-term).
So before choosing, you always need to weigh all the pros and cons of using anti-smoke.
Advantages and disadvantages of using an anti-smoke additive
As for the benefits, these include:
- friction on the working surfaces of internal combustion engine parts is reduced, which leads to an increase in their resource and the overall resource of the power unit;
- the amount of exhaust gases (smoke) decreases;
- noise during the operation of the internal combustion engine is reduced;
- the effect is achieved shortly after pouring the additive into the oil.
The disadvantages of antismoke include:
- Often the effect of their use is unpredictable. There have been cases when a very worn motor, after adding such a tool, completely failed after a while.
- The effect of antismoke additives is always short-lived.
- The chemical components that make up the anti-smoke leave carbon deposits on the surface of the internal combustion engine parts, which is very, and sometimes impossible, to remove.
- Some additives, by their chemical action, can critically damage internal combustion engine parts, after which it will be impossible to restore them.
so, whether to use additives or not is up to each car owner to decide. However, for the sake of objectivity, it should be noted that smoke additives should be used as a temporary measure that does not eliminate the cause of the breakdown. And in order to pour it into the internal combustion engine, they are only capable of it before the sale, so that it does not temporarily smoke (oil consumption cannot be recognized in such a short period). A reasonable person remembers the risks that accompany the use of such funds.
Popular additives rating
Based on the analysis of numerous reviews and tests of various anti-smoke additives performed by private car owners, we have compiled a rating of the most popular and effective of them. the list is not of a commercial (advertising) nature, but, on the contrary, aims to identify which anti-smoke additives that are currently commercially available are better.
Liqui Moly Visco-Stable
It is a modern multifunctional additive added to oil in order to stabilize its viscosity. In addition, it is designed to protect engine parts and oil composition (namely, when fuel enters the oil system). The composition of the additive is based on polymeric chemicals that increase the viscosity index. In accordance with the official description of the manufacturer, the additive Liquid Moli Vesco-Stabil protects the internal combustion engine elements even under extreme operating conditions (including frost and heat).
Real tests by car owners show that, compared to many other similar compounds, the additive shows good results (though not as magical as advertised). After pouring the additive into the crankcase of the internal combustion engine, the smoke of the exhaust system is indeed significantly reduced. However, this depends on the general condition of the motor and external factors (air temperature and humidity). Therefore, this additive was also placed in the conditional first place, that is, due to greater efficiency than others.
It is sold in a 300 ml can, the contents of which are enough for an oil system with a volume of 5 liters. The article of such a can is 1996. Its price as of the summer of 2018 is about 460 rubles.
stainless steel master
Products manufactured under the RVS trademark are a domestic analogue of imported additives (RVS stands for repair and recovery systems). There is a whole line of different recovery agents designed for gasoline and diesel engines with various volumes of oil systems. According to the manufacturer, all of them provide an increase in the compression of the internal combustion engine, compensate for the wear of the material on the parts, and create a protective layer on their surface.
However, the manufacturer immediately stipulates that these compositions cannot be used in internal combustion engines that are worn out by more than 50%. If the oil contains active Teflon, molybdenum or other additives, the internal combustion engine must be thoroughly washed before processing and replaced with oil without these additives. At the same time, the oil to which the additive is planned to be added must have at least 50% of the resource (middle of the service interval). Otherwise, you need to immediately change the oil and oil filter.
Each purchased product comes with detailed instructions for use! Be sure to follow the algorithm indicated there, since you need to fill in (use) the additive in two (and sometimes three) stages!
If the requirements are met, then real tests by car owners show that the RVS Master really reduces exhaust smoke, gives the internal combustion engine power, and reduces fuel consumption. Therefore, such compositions are unambiguously recommended as anti-smoke additives.
As mentioned above, there are several such formulations. For example, RVS Master Engine Ga4 is used for gasoline engines with an oil system capacity of up to 4 liters. Has an article - rvs_ga4. The price of the package is 1650 rubles. As for diesel engines, its name is RVS Master Engine Di4. It is also intended for internal combustion engines with an oil system volume of 4 liters (there are other similar packages, the last numbers in their names symbolically indicate the volume of the engine oil system). The packaging article is rvs_di4. The price is 2200 rubles.
XADO Complex Oil Treatment
It is positioned as an anti-smoke additive with a revitalizant, or an oil pressure restorer. In addition, like its other counterparts, it reduces oil consumption for waste, increases the thermal viscosity of engine oil, reduces wear on the internal combustion engine, prolongs its overall life, and is suitable for all internal combustion engines with serious mileage.
Please note that the agent itself must be poured in a heated state to a temperature of + 25 ... + 30 ° C and into heated oil. When working, be careful not to get burned!
Products manufactured under the brand name Hado have long established themselves among car owners on the positive side. Antismoke was no exception. Provided that the internal combustion engine is not worn out to a critical state, the use of this additive can significantly reduce smoke and increase the specific power of the internal combustion engine. However, this additive can be used more effectively as a prophylaxis (however, not completely new ICE, in order not to thicken the new oil).
It is sold in a 250 ml bottle, which is enough for an oil system with a volume of 4 ... 5 liters. The article of this product is XA 40018. The price is about 400 rubles.
Kerry KR-375
This tool is positioned by the manufacturer as a highly effective anti-smoke additive, specially designed for cars with significant mileage. This product is a mixture of ethylene-propylene copolymer, aliphatic, aromatic and naphthenic hydrocarbons. It can be used in both gasoline and diesel ICEs, including small ones. One bottle is enough for internal combustion engines, the oil system of which does not exceed 6 liters.
Real tests have shown that the Kerry antismoke additive is actually not as effective as it is written in advertising booklets, however, in some cases (for example, if the internal combustion engine is not very worn out), then it can be used, for example, as a preventive measure, especially considering its low price. Can be used at temperatures from -40°С to + 50°С.
Packed in a package of 355 ml. The article of such packaging is KR375. The average price is 200 rubles per pack.
MANNOL 9990 Motor Doctor
Additive for reducing oil consumption in internal combustion engines, reducing engine noise and exhaust smoke. In all respects, it is an analogue of the compositions listed above, in fact it is an oil thickener. According to the manufacturers, its composition forms a protective layer on the surface of the parts, which not only reliably protects the internal combustion engine even under significant loads, but also helps to smoothly start the engine in cold weather.
Real tests of this means are rather inconsistent. It can be noted that if the internal combustion engine is in more or less good condition, then this additive really reduces the noise of the engine. However, with regard to the “oil burner” and the reduction of smoke, the result is rather negative. so, the additive is more suitable for ICEs with not very high mileage and / or more wear, that is, for preventive purposes, than as a way to remove oily smoke.
Packed in 300 ml jars. The article of this product is 2102. The price of one can is about 150 rubles.
Hi-Gear Motor Medic
In accordance with the manufacturer's description, it is a high-quality additive for gasoline and diesel engines, designed to stabilize the viscosity of engine oil. it also increases compression, reduces oil waste, smoke and noise of the internal combustion engine.
in order to understand how effective it is precisely as an additive in order for the car not to smoke, it is enough to see that this additive is also placed at the very end of the list. So, real tests of the use of the additive High-Gear anti-smoke showed that It doesn't work as well as it says in the description.. namely, if the motor has significant wear, then it helps slightly, that is, it is rather suitable as a prophylactic composition for more or less new internal combustion engines. It is noted that the result of use is also very dependent on environmental conditions.
For example, in the warm season, the additive really shows good results, namely, it reduces smoke. However, at temperatures below zero Celsius, the effect is nullified. The same can be said about humidity. With dry air, the effect of reducing the amount of smoke takes place. If the air is sufficiently humid (winter and autumn, and even more so coastal areas), then the effect will be insignificant (or even zero).
Sold in a 355 ml package. The item number for this item is HG2241. The price of a canister as of the summer of 2018 is 390 rubles.
Runway Anti-Smoke
An additive similar to those listed above, whose tasks include reducing exhaust smoke, increasing ICE power and compression. The positive point is its relatively low price.
However, real tests have shown that Ranway antismoke actually shows one of the worst results among the analogues listed above. Although this, of course, depends on the conditions of use, the state of the internal combustion engine and other components. Therefore, it is up to the specific car owner to decide whether or not to use the Runway anti-smoke additive.
Packed in 300 ml packs. The article of such packaging is RW3028. Its average price is about 250 rubles.
Outside the rating, it is worth mentioning briefly about anti-smoke Bardahl No Smoke. It turned out to be outside the rating because the manufacturer himself on the official website declares that the product is intended only to reduce the amount of harmful substances in the exhaust gases (this state of affairs is caused by stringent requirements regarding the environmental friendliness of modern cars used in Europe). Therefore, its purpose is to reduce harmful emissions for a short time, and drive with such parameters to a repair point, and not to eliminate the symptoms of an internal combustion engine breakdown. So it's impossible to advise him, as it is found on some forums.
As for the feedback on the actual use of the Bardal anti-smoke additive, in most cases there really was an effect, which consisted in reducing the amount of smoke in the exhaust gases. The long-term effect depends on the volume of the oil system, the smaller it is, the faster the effect passes, and vice versa. In general, it is quite possible to buy an additive for the short-term removal of extreme smoke from an internal combustion engine. note that add the additive only to fresh (or relatively fresh) butter. Otherwise, there will be no effect, but on the contrary, hard-to-remove deposits may form on the surface of the parts.
However, for car owners who want to buy Bardahl No Smoke additive, we provide its trade information. So, it is sold in a package of 500 ml (for an internal combustion engine with an oil volume of 4 liters, it will be enough for 2 times). The article of the goods is 1020. The average price as of the specified period is about 680 rubles.
Hack and predictor Aviator
Remember that no matter what tool you choose, its composition is intended only to “mask” the malfunctions in the internal combustion engine. Therefore, such additives should be used for short-term removal of smoke and significant engine noise. And for good, you need to perform engine diagnostics, and on its basis, carry out appropriate repair work.
The best additive recipe is simple: take a piston and a handful of rings, add a pinch of MSC and a bowl of seals. After that, do not forget to look at the piston and liners in the engine. Having collected all the ingredients, mix them with DVSm, and then add a good oil. And when everything is ready, then move quietly and not make noise more than 3 thousand revolutions per minute for 5 thousand kilometers, otherwise the potion will not work. This is the best recipe, because the best additive to keep the car from smoking is a wrench and repairing the breakdown by replacing the broken part!
