Quite often, motorists have questions that the difference between antifreeges G11 and G12 can be mixed as they act and what to choose - more expensive or a budget option. Since a calm ride (without nerves, stops and boiling, especially in the heat) depends on the quality of the cooling system, this curiosity is appropriate, correct and not idle.
The classification on which antifreeze is marked with, is inherent company Volkswagen.. At first, only Tosols of this company were divided in a similar way. Over time, the rest of Europeans have joined it, and then the labeling began to use domestic manufacturers.
What is the difference between antifreeges G11 and G12, not all sitting behind the wheel are aware. There are drivers who ignore these foreign letters: a cooler and cooler, they are all the same. However, with such an approach you can stay for a long time without wheels and detect for large costs.
Antifreeze G11.
It can be said, this is familiar from the Soviet times the most common toosol. Made from the usual and standard ethylene glycol. In addition to him, the composition includes a slight set of additives (inorganic). The principle of operation lies in education on the entire surface of the cooling system of a kind of carbon, preventing unwanted corrosion.
On the one hand, as it were, the guarantee of the absence of rusting, on the other, due to this peel, thermal conductivity drops, cooling efficiency decreases. In modern auto opera, used exclusively for cars released until 1996.
Distinctive feature: Burns, loses the additives and ceases to act, as it should be, after quite short time.
Antifreeze G12.
The basis has all the same ethylene glycol, but with the addition of organics - carboxylate compounds. Plus a huge set of additional additives. W. different manufacturers It can be different both in composition and in proportions. Designed for high-speed engines with a strong temperature load. The entire system does not cover, attacks only affected areas.
Due to this, the degree of cooling is higher, the additive consumption is significantly more economical - as a result, successfully functions no less than 5 years On the intensively used machine. Recommended for cars until 2001 born (in Europe. We with a calm soul poured into newer).
An antifreeze G12 + is considered more improved. There are no borates, nitrites, amines, phosphates and silicates. According to European standards, it is suitable for cars that have come down from the conveyor until this day (although it is considered not entirely modern).
The most correct and suitable for modern cars - Antifreeze G13. It causes significantly smaller harm to ecology. Instead of ethylene glycol, the base in it is propylene glycol. Such toosol is not poisonous, very quickly decomposes - the manufacture is so expensive that in Russia and the rest of the CIS is not produced.
Connection opportunity
Top fluid with different indicators in each other, not recommended. And this applies to all oils, antifreeze and other substances. As for G11 and G12, two negative points are observed when they are associated:
- G12 loses its properties both under the top of the G11 and when adding G11 to it. Educated 11 Tosol Cork prevents the action of a more advanced G12, so overpayment for more modern antifreeze is in vain;
- if the toosols also different producers, no one will predict the consequences of their combination. There were cases when antifreeze additives reacted with each other so active that in the cooling system, a literal sense of the word jelly was formed.
Realizing what is the difference between antifreeges G11 and G12, the caring owner will rather carry a certain margin of native antimony than pouring out in the car. In the end, the eggplant with antifreeze is not a lot of space in the trunk.
Any work is accompanied by heat release. And engine internal combustion - not an exception. To provide an optimal environment for the motor operation, a special cooling fluid is used. It has the name of antifreeze. The names of this fluid on the market are very much, so it should be understood in the most basic types.
Brands G11 and G12. Antifreeze and its properties
Any motorist must have at least a surface view of the coolant, which is used in its machine. Each model has its own specific properties that should be considered.
Common requirements are made to the coolant, which allow the engine to work in optimal conditions.
Corrosion
Water and ethylene glycol is added to the composition. Unfortunately, this mixture has an increased ability to appear rust. And if we take into account that the engines of the car contain a large amount of alloy metals, then in the coolant, it is necessary to use the latest technology, allowing to withstand the occurrence of corrosion.
Frozening and boiling temperature
The first indicator is much lower than that of the water. This allows the engine to work even at the most severe temperatures. Also makes it possible not to expand when freezing, and do not damage parts with hoses in the system.
In addition, antifreeze G12 or G11 will have an increased boiling point, which allows to operate cars in the hottest conditions.
Cavitation and Combinability with Rubber
The fuel mixture in the cylinders during the explosion transmits the vibration of the coolant. It boils from such impacts. This process is called cavitation. It disrupts the condition of the film and destroys the metal. Antifreeze is obliged to resist the formation of microbubbles and create qualitative protection details from harmful effects.
The coolant should not be reacted with rubber hoses and seals in the internal combustion engine. It protects them from drying or cracking.
The most common stamps are G11 and G12. Antifreeze may also have the name G12 + and G13. Consider the main types separately.
G11. This class is intended for cars released before 1996, ethylene glycol and inorganic additives are included. The optimal life of the fluid in vehicle Makes up 2, a maximum of 3 years.
G12. Antifreeze is designed for cars collected and commissioned from 1996 to 2001. It is recommended to pour into engines operating at high temperatures and on large revs. The service life is 5 years. The composition has carboxylate compounds. It should be a little clarify what kind of chemical concepts.
Carboxylate antifreeze G12.
It was awarded such a name due to the composition added to the impurities that prevent corrosion. Their principle of operation is based on carboxylic acids. Unlike other components, they create a film not throughout the work plane, but only in those places where rust is formed. This allows you to increase the efficiency of heat transfer and do not cover the entire surface with the protective layer.
Also, the benefits of this type of coolant include the absence of silicon. This allows you to significantly increase the service life and avoid falling out the plaque.
Antifreeze color
Thanks to the added dyes, the fluids differ in each other. There is no longer than any operational properties. Color can be absolutely any. But since the liquid is a poisonous for the human body, bright and screaming shades are applied. For example, antifreeze G12 - red.
Manufacturers have agreed among themselves to make it easier to classify liquids. Standard is green color. Yellow antifreeze has an increased service life, and the red is the largest.
Mix liquids having different color is strictly prohibited. Additives do not interact with each other, but reduce the quality of antifreeze and its operation. If there is a need to replenish the tank to the required level, it is recommended to use simple distilled water.
Antifreeze G11 and G12. Difference
The first difference among these popular liquids is their coloring. This is not the main, but the most striking feature.
Red color is most often used for the G12 brand. Antifreeze G11 is produced green. However, it is necessary to be attentive because there are no certain prohibitions on the color. Any manufacturer can apply any recommended color for its products.
Ordinary people call the G11 Tosol brand. This is a mixture of ethylene glycol and simple water with various additives. The main drawback is a short service life, which is 2 years. Also, you have to use various impurities so that ethylene glycol does not energize the engine details.
Antifreeze G12 - red and not so poisonous. The main advantage is an increased service life, equal to 5 years. Due to carboxylate compounds, the fluid resists the corrosion and cavitations.
"LUKOIL" G12
Antifreeze "LUKOIL" G12 is a modern coolant that has all the necessary properties for the most optimal engine operation in passenger and trucks.
Due to carboxylate acids, antifreeze protects the motor from freezing, overheating, corrosion and cavitation. Confidently feels at a temperature of -40 degrees. Does not react and does not damage rubber and plastic products.
Qualitatively selected antifreeze is a warranty of long and successful work Engine in the car.
Antifreeze G-11 and G-12 - chemical compound with the use of aqueous solution designed to cool the engine at maximum loads. Its use directly depends on the cooling system and motor configuration.
For old models, release until 1996 inclusive, ordinary antifreeze, without sparing formulas and modern additives, are quite suitable for banal ovens. For subsequent brands of domestic and foreign cars, more modern cooling fluids are needed, which are capable of responding not only to modern norms of frost resistance and boiling, but also protection against different system sediments.
In this article, we will get acquainted with the main types of antifreeze (G-11, G-12, G-12 +, G-13), their properties, what is their difference, and can I mix these antifreeze among themselves?
In this regard, there is a generally accepted classification of antifreeze, which makes it easy to navigate the world of cooling liquids.
Antifreeze classification:
- antfriz G-11 - The basis of silicates and inorganic additives. It is interesting to know that the ethyl alcohol, which underlies the domestic antifreeze, also corresponds to the G-11 class, therefore the statement that antifreeze and Tosol is the same, it is possible to accept truth with confidence. The main use of antifreeze G-11 is predetermined in old cars, which differ from modern models with a large amount of cooling system. As mentioned more than once, the whole class of these antifreezes creates a special protective film, which is directed exclusively to protect against the effects of the aggressive medium inside the machine. Minus such protection is that the thermal conductivity is significantly reduced, which is why modern systems Cooling on new cars cannot be used such coarse, their thin channels of the cooling system will immediately bother with film formation and will not be able to provide sufficient circulation of antifreeze. The average booster temperature at the G-11 class is at 105 degrees Celsius. Optimal mileageThe manufacturer declared, ranges from 50,000 to 80,000 kilometers, which is on average for 2-3 years with a gentle operation of the machine.
- antfriz G-12 - compounds of propylene glycol with universal balanced additive packages, mainly made of carboxylate compounds of organic origin. All Class G-12 antifreeze is shown to use on modern cars with high-breed engines, which can be attributed to the class of heat-loaded. The average boiling point is 115 - 120 degrees above zero, although some analogues of G-12, can and overcome this threshold. The pressure in the cooling system directly affects the booster temperature of antifreeze in this class, therefore, depending on the modification of the machine, the coolant operations can be varied. Protective additives from corrosion and other deposits in the system work point. They are like a doctor, choose the place of illness and eliminate it by entering into a reaction with a chemical compound. The viscosity of such antifreezes is higher, and harmful components are reduced, unlike the entire class of the G-11 coolant. G-12 or red antifreezes, as they are also called, have a extended service life without loss of performance, which can be correlated from five years or an approximate mileage of 250,000 kilometers.
- Antfriz G-12 + -the next generation, with a more improved and adapted formula. Chemistry of this class considers less harmful and for humans and for ambient. The G-12 + is also the same as an organic organic, arched by more modern additives. The rest of the differences between the G-12 and G-12 + were not detected, although many autocontracens declare this class of antifreeze for their car.
- antfriz G-13 - This is a new variant of coolant based on propylene glycol, although this statement is controversial. It was previously apparent to assume that all three of the previous class were at their own ethylene glycol. Indeed, before the development of new propylene technology, it was exactly the case, but with the advent of the synthesis of propylene, almost all classes G-12 and G-12 + are also belonging to the component G-13, which is designed to cool the engines of sports cars, motorcycles and others similar in characteristics power aggregatesoperating on extreme loads in extreme conditions.
The difference between antifreeze G-11 and G-12?
You can mix the homogeneous bases among themselves and that, it is desirable from one manufacturer to prevent conflict additives. In other words, it is necessary to read the label and make sure that for a mixture, both antifreeze have the same basis of ethylene glycol or propylene glycol. If you mix the two of these components with each other, then with a 100% warranty, the mixture or foam, or will give a precipitate in expansion tankSometimes flakes can be on its surface.
To the question - is it possible to mix antifreeze G-11 and G-12, the response to the surface: under any circumstances do not interfere with G-11 and G-12 !!! Even with their identical basis. The difference in additives will also give a precipitate, flakes, rusty shade or at best will reduce the life of G-12.
For mixing can be in emergency cases Send the G-11 and G-12 + systems, the latter has a more neutral formula. In this case, the nuclear cocktail should be replaced at the first opportunity, pre-flushing the cooling system several times with distilled water or special tool. It seems that the answer to the question is what the difference between the antifreeges G-11 and G-12, and is it possible to mix them - this is exhaustive.
The main thing is to act according to the instructions given by the automaker, then many problems will arrive at you, and your car.
The car when it is involved, constantly resides in motion. And it concerns this, not only movement on the road, but also the movements of its individual parts that are inside. And any friction, as you know, leads to heating. So, we need to take care of the high-quality cooling of the motor.
For this, special substances under the name of antifreeze that have low temperature Viscosity. This is advantageously different from simple water, which can damage individual components, if the temperature is less than zero.
Tosol - last century, now modern motors Cool antifreeze
Until recently, all fluids that are designed to cool the engine were called "Tosol", but now people began to distinguish antifreeze on different types. In general, there are variants on saline and on an acid-based basis. And so that motorists do not confuse them among themselves, they are all painted in different colors. In the case of salt solutions, we can see the blue or green shade, while the acidic options have a characteristic red color.
The choice of a particular type of antifreeze depends on what materials the manufacturer worked when creating a motor cooling system.
Antifreeze G11 - almost toosol, only with additives
The liquid component of antifreeze is represented by a substance called ethylene or polypropylene glycol.
Since the first of these two components has elevated level Toxicity, most manufacturers stop their choice in the second version. So, it is impossible to mix different types of liquids. And, if necessary, replacing antifreeze, it must be completely merged from the system, replacing the new one.
G11 and G12. Features and differences
Some of the most popular types of antifreeze, which are common in our country, are considered G11 and G12. They are quite different among themselves, which indicates the inadmissibility of mixing them. And today we learn what is the difference between antifreeze G11 from G12?
Antifreeze differ significantly in color
So, in front of many drivers the question arises, choose them G11 or G12? So, G12 is a red liquid (in some cases - yellow), which is a carboxylate antifreeze. This substance is characterized by a local action, due to which, in the event of an occurrence in the system of corrosive lesion, additives can help localize it in their place, not allowing to spread further.
Video about the main differences of these types
Highly interesting video The fact that the types of antifreeze are distinguished, the main production technologies, the functional differences between G11 from G12, also considered the type of antifreeze G12 ++.
Thus, antifreeze can serve you long enough, in some cases, much longer than five years. And then, his replacement is appropriate only when the additives begin to exhaust their properties.
As for the antifreeze denoted by the G11 index, it is represented by a substance of the type of silicate component. It can have almost any shade. It can be green or blue, yellow or orange, and sometimes even red. But, nevertheless, the red color of this substance is almost never found.
It is this substance in our country to be appointed to Tosol, as it is its almost complete analogue. This liquid affects the system and its walls, covering them with a special protective layer. But, the service life of this substance is not very big - only three years.
Replacing antifreeze G11
If you used only one of these types of antifreeze, then you need to change it to another with some reservations. We are talking about the fact that after G11 remains an old protective film, which does not allow the antifreeze with due efficiency. In addition, it will be necessary to change it in three years of operation of the car. But Tosol, which is filled after the G12 brand, immediately stops the impact of the latter on the wall walls. Thus, you need to use the same coolant brand continuously, and mixing them is prohibited at all.
Exceptions
But, there are exceptions. So, it is possible to mix with Tosol antifreeze called G12 +, which has practically the same properties as G12. In this situation, the only negative point will be only that the validity of antifreeze will suffer, decreasing to the mark in three years.
Need to take into account the composition of liquids
In general, you do not need to fully rely on color markingAs adopted in the medium of domestic motorists. Optimally, if you read the composition of antifreeze G11 or G12 carefully, focusing on the presence of the same components in the composition.
What kind of Tosol belongs to?
As we said, Tososol's name has become a nominal. But, what specific type of antifreeze is this product? Thus, a substance called Tosol A-40, if it is prepared correctly, must repeat the composition G11 with all its components and additives. However, many experts do not recommend using modern toosol in cars.
Disadvantages of Tosla
The reason for this lies in the fact that in the specified substance there are practically no inhibitors of foreign processes of foreign production, which would be able to provide all protective properties. In addition, many minor firms that do not have access to the correct recipe, as well as to the production of Tosol today necessary components. As a result, many studies have shown that a significant part of products with the Tosol title, which is currently represented in the market, is nothing more than a mixture of ethylene glycol, ordinary water and a dye of one or another color, most often - blue.
About mixing antifreeze.
Many do not know whether antifreeze can be mixed with G11 and G12. Despite the fact that the same substances are included in antifreezes, some components may differ, which makes a mixture unsuitable for mixing among themselves.
Also, you should not try this cooling fluid to taste, because it is capable of damage to health, including poisoning. Antifreeze differences are in the presence of lubricating components and substances with anti-corrosion properties. They are also distinguished by aggressiveness to the glands, gaskets and pipes, freezing temperature and boiling point.
Possible problems when mixing antifreeze
Color features are provided with just dyes, which are added to the composition. Ideally, antifreeze of different manufacturers, but one color, you can safely mix each other. And this is so if we are talking about proven brands. Exceptions are only fakes, when colors are determined chaotic, depending on the desire of buyers, not the characteristics of the composition. If the compositions are not similar, that is, the chance that this substance will foam and even falls into the sediment.
If you are critical of the possibility of further mixing antifreeze, you need to always buy G12 or G12 +, as they have a property to respond normally to any other substances that fill them, even in the case of G11.
Similar liquids, almost always, have a bright red color that distinguishes them.
And, of course, do not forget what recommendations are given by the manufacturer of your car, since the difference between the antifreeze G11 from G12 is quite significant.
For example, Tosol will suit not all cars, since its composition includes some aggressive components that may damage new foreign cars, while domestic cars Pretty easily tolerate it. Moreover, Tosol and was in the past century, designed for cars produced under the VAZ brand.
The engine operation of the car inevitably leads to its heating. To avoid overheating of the motor, antifreeze is used - cooling low-temperature fluid, allowing the engine to withstand high loads and stably work.
A variety in the antifreeze market is very large. They are different colors, have a variety of additive packages and differ in classifications. In this article we will tell you what antifreeze G11 and present a few species from the most popular brands.
Antifreeze G11 in its composition has a mixture of ethylene glycol, water, a package of special additives and a dye that gives the coolant color. Type G 11 cooling fluid is most often blue and green, less often yellow and red. Antifreeze color does not affect its properties and characteristics. Coloring is intended only for "individuality", which also helps to determine the level of fluid in the expansion barrel.
Antifreezes of type G 11 are hybrid, due to the content of organic inhibitors and inorganic - silicates, nitrites, phosphates, depending on the production technology.

Properties
The properties of antifreeze G11 admission to many depend on the additive package that the manufacturer adds to its product. The service life of G 11 is not a bol of three years. The nature of the work in the interaction of the coolant with the entire surface of the cooling system elements, covering everything with the protective film, with which it comes into contact.
