The better antifreeze or "Tosol"? Is it possible to interfere with Tosol with antifreeze?

Very often novice motorists not only do not attach special importance to the engine cooling system of the car, but also have no idea about what is generally flooded in the case with their own car. This attitude frankly amazes and discourages. After all, on the right choice depends not only on the technical condition of the machine, but also on your own health. Today we will talk about the better antifreeze or Tosol compared to each other.

Prehistory

In principle, such a dispute could arise only in our country, since only we have such a classification of this type of liquids. The fact that "Tosol" - the same antifreeze, but the Russian production. Because of this, many motorists are extremely wary of its performance, preferring not to fill this composition in expensive and high-quality cars.

For the sake of justice it is necessary to say that the risk of "breaking into" a fake in this case is indeed quite large, but foreign antifreeze is forged a little less often. So the very formulation of the question of what is better antifreeze or "Tosol", if we compare their quality, is not too correct. It's stupid to compare the same liquid. You can slightly alter this topic: the better (or worse) domestic cooling liquid in comparison with its foreign counterparts?

To answer this question, you need to know the theoretical part. Of course, you can not find out all about antifreeze and antifreeze from such a short material, but the most important information you can get for sure.

General operational information

As almost all automobile experts testify, at least 20% of all engine failures are associated with the cooling liquid directly, and another 44% indirectly. Therefore, its correct selection will help to save a lot of money, since the engine overhaul is an event that is difficult to classify as particularly cheap (especially with current exchange rates).

As a rule, all cooling liquids in their composition contain compounds of ethylene glycol (very rarely propylene glycol), as well as water and a large number of additives, the sole purpose of which is to prevent corrosion processes. And here "the dog is buried": the actual difference of mixtures of different manufacturers in the sets and composition of additives that are used in the production of products.

In principle, they constitute the main commercial secret of producers, since all properties of the products they sell depend on these substances.

What should I focus on first?

To answer the question, the better antifreeze or "Tosol" for your car, it is important to read the instructions or the service book in which the manufacturer is obliged to give full information about the preferred type of coolant and the nuances of its use. Often, Western companies indicate specific brands of antifreeze, which should be used in their cars. They went through the whole spectrum of research and tests, and therefore guaranteed not to harm your car.

However, enough lyrics. It is important for us to know, the better antifreeze or "Tosol", if we compare these liquids with each other. In order to answer this question, you should know that these compounds are manufactured using three different technologies.

  • Traditional . In this case, additives based on inorganic acid salts (i.e., silicates, nitrites, nitrates, phosphates, etc.) are used.
  • Carboxylate (OAT) . If you understand chemistry, you will understand that in this case, they use, on the contrary, salts of organic acids (carbonates, to be more precise).
  • Hybrid . In this case, the cooling liquid is created on the basis of a package of additives of organic origin, which contain a small amount of silicates and / or phosphates.

So what antifreeze is better, why? But now we come to the most important thing. Domestic is produced according to the traditional scheme, while the import is made by carboxylate technology. Accordingly, in order to understand their strengths and weaknesses, it is necessary to know the similar characteristics of the compositions. We will analyze the eight main features that manifest themselves in the daily operation of the engine of any car.

To interfere or not to interfere?

By the way, is it possible to interfere with "Tosol" with antifreeze? If you carefully read the information outlined above, then you already know the answer. No, it's not worth it. Moreover: look at the colors of different types of antifreeze from different manufacturers. Another tip. Before changing the antifreeze (or "Tosol"), rinse the engine thoroughly with distilled water. The new composition can be filled only after the absolutely pure liquid has drained from the cooling system.

Mixtures even from one firm, but having a different color, should not be thwarted. But even the compositions from different manufacturers, but the same in color, it is possible to add one to another. Nothing catastrophic in this case will happen. So you found out whether Tosol can be thwarted with antifreeze.

Coolant replacement procedure

It is always useful to repeat the procedure for replacing the coolant.

  • We put the car so that the front part of it has a small slope down.
  • Unscrew the plugs and drain the fluid in a pre-filled container with a wide mouth.
  • The cooling system is washed with ordinary distilled water, to which it is desirable to add a special cleaning mixture. Water poured, twist all the caps and plugs. After this, it is necessary to start the car and turn on the interior heater at full power. Allow him to work for at least ten minutes.
  • The spent solution merges, the procedure is repeated two to three more times.
  • At 2/3 fill the receiver with antifreeze compound and, leaving the cork open, start the car engine. This will remove all the air jams from the system. We wait the same ten minutes, add antifreeze to the required level, close the tank.

Engine cooling efficiency

At first glance, traditional technology is good because it mechanically protects the metal from corrosion. How? These compounds form a layer of thickness up to 0.5 mm, which, deposited on the surface of the parts, prevents the development of corrosion processes.

That's just the thermal conductivity of this film is so bad that cooling the engine can be reduced by 50%, which is not good. Simply put, the domestic "Tosol" can often act as an excellent insulator! The engine starts to systematically overheat (albeit not critically), and this leads to its exploitation under conditions to which it was not technologically adapted. It wears out more quickly, fuel consumption sharply increases and power falls.

Carboxylate liquids in this respect are clearly leading. They also form a protective layer, but its thickness does not exceed 0.0006 mm (60 angstroms). This film has virtually no effect on the process of removing heat from the engine, and therefore it does not overheat. So it's better: antifreeze or "Tosol"? How to choose between two types of liquids, can you really be guided only by this characteristic? Of course not.

Term of use of a cooling liquid

Experts confidently assert that in almost 90% of cases, when it comes to domestic antifreeze, as additives, mainly silicates and nitrites are used. Silicates are added in this case in order to protect aluminum, while nitrites work effectively against cavitation erosion.

Of course, the composition of the coolant is optimally balanced. But if it happens that some component is consumed, Tosol quickly loses all its properties, and therefore poorly protects the engine from both overheating and corrosion. The fact is that due to high temperatures and other factors, silicates and nitrites almost completely precipitate after 30-35 thousand kilometers of run. Accordingly, the cooling liquid loses almost all its properties after this period.

Liquids produced on the basis of organic salts, practically do not reduce their qualities throughout their operational period. The additives practically do not precipitate, the solution remains practically homogeneous throughout the entire period of use. So, many foreign antifreezes can normally be used for two years (no less than 100 thousand kilometers of run).

But! In advance we warn beginning car enthusiasts that replacing the coolant ("Tosola" or antifreeze) should be done in a timely manner, and not after the composition turns into something completely unsightly.

Protection of aluminum and aluminum alloys under conditions of high temperatures and high loads

It is no secret that the modern automobile industry is increasingly attached to the use of aluminum and its alloys. In particular, even engines are made of these materials. It must be said that our cooling fluids are very poorly combined with aluminum, since they practically do not protect this substance from destruction under extreme temperatures and loads.

The researchers found that at temperatures above 105 degrees Celsius "Tosol" practically ceases to protect aluminum. Actually, because of this feature, it has long been not used by manufacturers of all leading automotive brands.

In contrast, carboxylate formulations in this area show the highest possible values. Specialists, having conducted numerous tests for dynamic corrosion in various conditions, found that high-quality antifreeze will allow the engine to be operated from aluminum alloys by 45-60% longer.

Liquid pump service life

It is known that the main reason for the liquid pump outage is hydrodynamic cavitation. Simply put, this formation of numerous gas bubbles in the liquid and their rapid collapse at the working surfaces of the mechanism. As a result, the materials are subjected to a real hydrodynamic attack every second, which contributes to the rapid destruction of the metal. Over time, caverns are formed, and parts fail.

Here, in this case, I would like to recommend not "be carried out" on the proclamations of producers. The laws of physics can not be fooled, and therefore there is practically no difference between antifreeze and "Tosol". No increased protection of antifreeze in this case can not provide.

Protection of the engine shells from cavitation

The harmful effects of high-temperature cavitation also affect the cylinder liners of automobile engines. In this case, "Tosol" manifests itself better. We have already said that it forms a thick protective film, which much more effectively prevents the destruction of metal.

Stability of composition and properties

Silicates, which are used in the production of "Tosola", have an unpleasant habit of transitioning into a gel-like state. Phosphates, which also form part of this type of coolant, tend to precipitate during frequent heating and cooling cycles. Together with the gels, all this forms a "hellish mixture", which completely clogs the radiator and interferes with the normal operation of the cooling system of the car engine. On the contrary, liquids based on carboxylate formulations are completely devoid of such drawbacks.

Compatibility with plastics and elastomers

In the cooling system of modern machines, plastic, elastomeric, rubber and silicone elements are widely used. Carboxylate formulations do not have any negative influence on these materials. However, high-quality "Tosol" also does not destroy rubber, plastic and silicone, so in this respect the compositions are almost equal.

This is also evidenced by long-term studies of domestic and foreign car manufacturers, which could not reveal any significant differences in this area.

So it's better: "Tosol" or antifreeze, and how to distinguish them? In general, everything is simple. For older cars with cast-iron engines, there is no particular difference. Perhaps, in this case, more suitable "Tosol" (due to the low price). Visually, however, it is impossible to distinguish these compositions, one has to rely solely on the honesty of the manufacturer. Therefore, we recommend buying coolants only in specialized stores.

There is nothing wrong with using Tosol instead of antifreeze, but it's always unpleasant to overpay for cheap liquid sold under the guise of a more expensive one.

Some ways of differentiation

However, there are some ways. So, some "experts" advise to taste the composition: it is considered that "Tosol" is sweet, since it contains a lot of ethylene glycol. That's only to use this way, we would strongly advise, since all the fluids for cooling the engine are poisonous (to some extent). How else can we distinguish Tosol or antifreeze? How can I find out what's in the tank?

If you can pour a small amount of the composition into a vessel, do this and look at the process: in its "texture", "Tosol" looks more like vegetable oil, while the antifreeze looks like ordinary water the most. Remember that the color of the composition does not say anything, since it depends only on the dyes, which you can add any (which sellers of counterfeit products use).

Thus, in most cases antifreeze is in the lead. Especially it concerns new cars that have been produced in the last few years. So we practically answered the question about what is better: "Tosol" or antifreeze (and why). It remains to clarify a few small details.

Ecology care

Here, the carboxylate formulations show better results. And it's not so much in their chemical composition as in banal logic. They need to be changed much less frequently, and therefore much less harm is done to the environment. Finally, yes, from the point of view of chemistry, carboxylate mixtures are still much better, since they are easier to dispose of, so that they do not harm the environment.

So you found out what is better: antifreeze or Tosol, whether these mixtures can interfere, what their characteristics are. We hope that our recommendations turned out to be useful for you.
