Any work is accompanied by the release of heat. And the internal combustion engine is no exception. To provide an optimal environment for the operation of the motor, a special coolant is used. It is called antifreeze. There are a lot of names of this liquid on the market, so you should understand the most basic types.

Grades G11 and G12. Antifreeze and its properties

Any motorist should have at least a superficial idea of ​​​​the coolant that is used in his car. Each model has its own specific properties that should be taken into account.

Serious requirements are placed on the coolant, which allow the engine to work in optimal conditions.

Corrosion

Water and ethylene glycol are added to the composition. Unfortunately, this mixture has an increased ability to rust. And if you take into account that car engines contain a large amount of light alloy metals, then it is necessary to use the latest technologies in the coolant to resist corrosion.

Freezing and boiling point

The first indicator is much lower than that of water. This allows the engine to operate even in the harshest temperatures. It also makes it possible not to expand when freezing, and not to damage parts with hoses in the system.

In addition, G12 or G11 antifreeze will have a high boiling point, which allows you to operate cars in the hottest conditions.

Cavitation and compatibility with rubber

The fuel mixture in the cylinders during the explosion transmits the vibration of the coolant. From such influences, she boils. This process is called cavitation. It violates the state of the film and destroys the metal. Antifreeze must resist the formation of microbubbles and create high-quality protection of parts from harmful effects.

The coolant must not react with the rubber hoses and seals in the internal combustion engine. It protects them from drying out or cracking.

The most common grades are G11 and G12. Antifreeze may also be called G12+ and G13. Consider the main types separately.

G11. This class is intended for vehicles manufactured before 1996. The composition includes ethylene glycol and inorganic additives. The optimal life of the fluid in the vehicle is 2, maximum 3 years.

G12. Antifreeze is designed for vehicles assembled and commissioned from 1996 to 2001. It is recommended to fill in engines operating at high temperatures and at high speeds. The service life is 5 years. It contains carboxylate compounds. It is necessary to explain a little what these chemical concepts are.

Carboxylate antifreeze G12

He was awarded this name because of the impurities added to the composition that prevent the occurrence of corrosion. Their principle of action is based on carboxylic acids. Unlike other components, they do not create a film on the entire working plane, but only in those places where rust forms. This allows you to increase the efficiency of heat transfer and not cover the entire surface with a protective layer.

Also, the absence of silicon in the composition can be attributed to the advantages of this type of coolant. This allows you to significantly increase the service life and avoid plaque.

Antifreeze color

Thanks to the added dyes, the liquids differ from each other. The color does not add any more operational properties. The color can be absolutely anything. But since the liquid is poisonous to the human body, bright and flashy shades are used. For example, G12 antifreeze is red.

Manufacturers have agreed among themselves to make it easier to classify liquids. The standard color is green. Yellow antifreeze has an extended service life, and red has the longest.

Mixing liquids of different colors is strictly prohibited. Additives do not interact with each other, but reduce the quality of antifreeze and its service life. If it becomes necessary to replenish the tank to the required level, it is recommended to use plain distilled water.

Antifreeze G11 and G12. Difference

The first difference among these popular liquids is their coloration. This is not the main, but the most conspicuous feature.

Red color is most often used for grade G12. G11 antifreeze is available in green. However, you need to be careful, because there are no specific prohibitions on coloring. Any manufacturer can apply any recommended color for their products.

Ordinary people call the G11 brand antifreeze. It is a mixture of ethylene glycol and plain water with various additives. The main disadvantage is the short service life, which is 2 years. You also have to use various impurities so that ethylene glycol does not corrode engine parts.

G12 antifreeze is red and not as poisonous. The main advantage is an extended service life of 5 years. Thanks to carboxylate compounds, the liquid resists corrosion and cavitation well.

Lukoil G12

Antifreeze "Lukoil" G12 is a modern coolant that has all the necessary properties for the most optimal engine operation in cars and trucks.

Thanks to carboxylic acids, antifreeze protects the engine 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 guarantee of long and successful operation of the engine in a car.

Reading 4 min.

Lukoil produces two antifreezes of the G11 standard: Green and Blue. With a different appearance, they are produced using the same technology.

Description of antifreeze

Antifreeze Lukoil G11

These two Lukoil coolants are produced using hybrid technology, which combines organic and inorganic elements. Thanks to it, antifreeze simultaneously creates a protective film on the surface of parts and concentrates corrosion inhibitors where the metal begins to break down.

Lukoil G11 antifreezes have a service life of three years. They have a very low crystallization temperature - minus 40 degrees Celsius. Therefore, they are called low-freezing coolants. Reliably protect the system from freezing, corrosion, scale formation and overheating.

Composition, color, standard

Information on the label Lukoil BLUE

Both coolants are made using hybrid technology, using silicates and organics at the same time. It consists of ethylene glycol as a base, as well as silicates and salts of organic acids.

Antifreeze Lukoil Green has a green color.

Lukoil Blue antifreeze has a blue color.

Both Lukoil G11 fluids have the same composition and characteristics. They differ only in color. The use of bright dyes allows you to distinguish antifreeze from other liquids and find leaks in time. Coolants of the G11 standard are most often painted in green and blue tones, but this is not regulated by anyone and depends only on the desire of the manufacturer. Also, the manufacturer makes it possible to choose a mixing liquid that is close in color to the one already used, of course, if they are identical in composition.

Interesting! The classification of antifreezes for G11, G12 and others is not international and is borrowed from the Volkswagen concern.

Scope of application

Blue antifreeze Lukoil

Lukoil Antifreeze G11 standard can be used in various vehicles manufactured by AvtoVAZ, BMW, MAN, Opel, Scania and others. And Lukoil Blue antifreeze has special recommendations from the Czech company Ferrit s.r.o.

Important! Antifreezes produced using hybrid technology can be mixed with other analogues. However, products from different manufacturers may lose some of their properties when mixed.

Advantages and disadvantages

Here are the advantages of green and blue antifreeze from Lukoil:

• low crystallization temperature;
• creation of a protective film on the surface of parts;
• effective protection against overheating and freezing;
• stable properties in different conditions;
• universality;
• cavitation protection.

In terms of properties, hybrid antifreezes are somewhat inferior to carboxylate and lobrid ones. In particular, they have a shorter service life. However, silicate ones are superior.

Antifreeze red - green - blue. What is the difference? Just about complex

Antifreeze is the general name for technical automotive fluids that are used to cool internal combustion engines. The boiling point of an ethylene glycol or propylene glycol based combination mixture is higher than the average operating temperature inside the motor, and the freezing point is below freezing. Due to this difference, the engine does not boil and starts without problems in conditions of negative temperatures, for example, in winter at -10..-40 degrees Celsius. The purpose is clear, it is more difficult to figure out what is the difference between red, green and blue antifreeze. To understand this, you will have to study the composition, the main properties of the components and understand the principle of operation of coolants.

The composition and properties of the coolant

The composition of antifreezes of different colors is practically the same. The basis for mixtures of this type is the same - dihydric alcohol and water. In addition to them, manufacturers add anti-corrosion, anti-cavitation, anti-foam and fluorescent additives to coolants.

Pure dihydric alcohol - ethylene glycol, propylene glycol - freezes at a temperature of -12.3 degrees. When mixed with water, whose freezing point is 0 degrees, a eutectic occurs that changes the properties of the finished product. Therefore, the crystallization temperature of the finished antifreeze is much lower than that of its components - up to -75 degrees.

Antifreezes are based on a water-glycol mixture, which ensures their resistance at low temperatures.

A pure mixture of alcohol and water is quite active. Without specialized synthetic and organic additives, such a coolant will destroy the engine from the inside in a matter of months. To prevent this from happening, manufacturers add:

• corrosion inhibitors;
• anti-cavitation substances;
• Anti-foam components;
• Fluorescent dyes.

Corrosion inhibitors form a thin protective film on the inner surface of the engine and its components, which prevents active alcohol from destroying the part. Anti-cavitation and anti-foam components minimize the destructive effect of local boiling on the walls of the unit. Fluorescent paint is needed to detect a possible coolant leak.

What color is antifreeze

Today the market offers dozens of types of coolants. It was in the Soviet years that car owners did not know other options, except for "antifreeze", now when you look at the counter of a car dealership, it's easy to get confused. To simplify the selection process among the mass of proposals, manufacturers have introduced a unified coolant classification system: TL 774. Initially, the classification was born within the Volkswagen concern, but quickly spread to the entire global market for the segment's products.

According to TL 774, the following classes of antifreezes are distinguished: G11, G12, G12 +, G12 ++, G13. G11 is almost always green; G12, G12+ - red; G12 ++, G13 - purple coolants of the latest generation.

Blue (antifreeze)

The color of antifreeze familiar to a Russian person is blue. It was in blue that the first Soviet silicate coolant "antifreeze" was painted. This was done so that by changing the color of the technical fluid, the car owner could determine the degree of its production, and take care of flushing and replacing the cooler in time.

"Tosol" is produced from a mixture of ethylene glycol, water and inorganic additives: silicates, nitrites, phosphates, amines and their combinations. The service life of inorganic inhibitors is up to 2 years, and the permissible operating temperature limit rarely exceeds 105-108 degrees. Modern internal combustion engines operate at higher temperatures, therefore, with such a coolant, the engine will fail very quickly.

Antifreeze contains 20% distilled water, and everything else is ethylene glycol

Advantages of "antifreeze":

• Low price.

Cons "antifreeze":

• Low boiling point;
• Inorganic additives harmful to surfaces;
• Service life - up to 2 years.

Green (G11)

Hybrid antifreeze G11 is tinted with a green dye of different saturation, less often with yellow or turquoise. It is based on the same ethylene glycol with water and inorganic inhibitors, but less active than in antifreeze.

Silicates and phosphates in the composition of green antifreeze are less dangerous than "Soviet", but this class of coolants is rarely allowed to be used in engines of the latest generations.

G11 antifreeze is usually green, but can be yellow, turquoise, and even blue.

• Phosphate film protects the internal walls of the unit from the corrosive effects of ethylene glycol;
• The boiling point is below operating temperature in car engines older than 10 years.

Cons of G11:

• Phosphate film reduces heat dissipation;
• The protective coating crystallizes and crumbles over time;
• Service life - up to 3 years.

At a price, green antifreezes are not far from antifreeze, so they are often chosen to service domestic cars or old foreign cars.

Red (G12)

G12 carboxylate antifreeze is tinted with red - from pale to rich burgundy. Anti-corrosion additives in them are of an organic nature - they are synthesized from carboxylic acids. Carboxylate inhibitors work pointwise: they do not cover the entire inner surface of an automobile engine with a protective film, but only areas with incipient corrosion. At the same time, the coating is so thin that the coefficient of heat removal to the external environment practically does not decrease.

According to Volkswagen representatives, it is red antifreeze that is considered the best solution for most internal combustion engines.

G12 antifreeze does not protect aluminum radiators from oxidation, however, for copper or brass, red antifreeze is the best choice.

• Point impact on the centers of origin of corrosion;
• No effect of crystallization of the protective film;
• Can be changed no more than once every 5 years.

Cons of G12:

• Additives do not prevent the occurrence of corrosion foci, but only act locally on existing damage to the surface of the unit;
• Carboxylate mixtures are not effective for protecting aluminum radiators.

At the time of its first appearance on the market, G12 red antifreeze and its modification G12 + were considered a major breakthrough in the development of effective automotive coolants. Against the background of examples from previous generations, the disadvantages of carboxylate antifreeze do not look significant.

Purple (G13)

Lobrid antifreezes G12 ++ and G13 are painted purple. They were invented relatively recently - in 2012. The product is based on almost harmless dihydric propylene glycol and organics, supplemented with mineral additives to protect and enhance the effectiveness of the composition.

Organic silicates are used to create a protective film with a porous structure that prevents overheating of the walls of the unit. Carbon inhibitors work pointwise - they accumulate in places where corrosion originates and prevent it from spreading further.

Unlike previous coolants, class G13 antifreezes contain a propylene glycol base.

Pros of G12++ and G13:

• Infinite service life, subject to filling in a new engine;
• Less environmentally hazardous composition of the base and additives;
• High boiling point - from 135 degrees.

Cons of G12++ and G13:

• High price.

In fact, additives of different colors are different generations of coolants. Those invented earlier are more environmentally hazardous and less effective when compared with more modern developments from automotive chemical manufacturers.

What is the difference between coolants of different colors

In the store you can find traditional, hybrid, carboxylate and labrid types of antifreeze. They differ in color, as well as key properties inherent in coolants. The easiest way to explain the differences is by the example of the main properties for which coolants are used for internal combustion engines:

• Corrosion protection. Traditional "antifreeze" practically does not provide it, while red and purple antifreezes, due to additives, are able to maintain the integrity of the components and internal surfaces of the unit for quite a long time.
• Boiling temperature. The higher it is, the better the fluid prevents the engine from overheating during operation. For blue and green trains, it is in the range of 102–110 degrees, which, with an average operating temperature of the engine of a modern foreign car of 105–115 degrees, is considered an extremely low indicator. For comparison: purple coolant boils at 135-137 degrees.
• Freezing temperature. It must be lower than the absolute weather minimum in the region where you will operate the machine. The average for all coolants is -20 .. -40 degrees. But traditional and hybrid ones, when cooled below zero, almost immediately begin to thicken, which complicates the operation of the motor; this does not happen with carboxylate and labrid ones.

Some manufacturers use expensive additives, others are cheap, but the color of the coolant does not depend on the composition, but on the dye

From the foregoing, the conclusion follows: the more recent the development, the more effective it is in all parameters required when assessing the quality of the coolant.

Is it possible to mix antifreeze of different colors

Do not mix antifreezes of different colors. Even liquids of the same class, but from different manufacturers, are undesirable to be poured into the engine at the same time. When interacting, the additives level out the action of each other, thereby worsening the properties and reducing the service life of the coolant.

There are exceptions to the rule, but only for emergencies. So, a mixture of antifreeze of any category with G13 is considered suitable for use, but has a weakened anti-corrosion effect. Regardless of the proportions in which the compositions were mixed, the result will be similar in properties to the lower category product. For example, if you mix G11 and G13, the result will be similar to pure green antifreeze.

The only significant reason to experiment with mixtures is when you urgently need to add liquid to the system, but you don’t have the necessary one at hand. At the first opportunity, the “cocktail” must be drained, flushed and filled with new coolant. Unfortunately, there is no guarantee that an improvised mixture of technical fluids will not harm the engine in the long run.

Table for adding antifreeze to the cooling system

There are no good and bad antifreezes. Coolants of different colors differ in properties due to the difference in composition. Which cooler to choose depends on the type of engine. Therefore, when choosing a coolant for a car, it is necessary to look first of all at the manufacturer's recommendations for a particular unit.

Like oil, coolant requires regular replacement. The use of a used compound is hazardous. Poor quality cooling leads to higher operating temperatures in the engine. This, of course, causes accelerated wear of the moving parts of the unit and the need for an early repair. Drivers do not need to explain how much it costs to overhaul the motor or replace it. That is why antifreeze should be replaced in a timely manner.
Many car owners do not know which product to choose, how g11 antifreeze differs from g12 and other types. This is an extremely relevant issue, since the use of the wrong fluid can lead to serious problems. You should clearly navigate the characteristics and current products on the market.

G12 Features

Antifreeze (or antifreeze) is a complex composition that contains ethylene glycol as a base. As a rule, the composition is red. It is used only on cars with a year of manufacture 1996-2001, while it has a fairly long service life (up to 5 years). G12 is able to identify points of potential corrosion development in the structure, as well as stop the source. This effect is achieved through the use of some additives that create a microfilm in problem areas.
The modern market offers drivers G12 + antifreeze models. There are no fundamental differences, because it is just a slightly modified fluid that can be used in newer cars. It is possible to talk about the advantages and disadvantages of products under this marking only in comparison with other products (with G11 or G13). We will talk about this in more detail in the following sections.

Composition and characteristics

Antifreeze G12 consists of several components:

• About 90% is ethylene glycol. The main task of this substance is to prevent the composition from freezing.
• Red dye. It is necessary to visually distinguish the liquid from others.
• Up to 5% - distilled water.
• Up to 5% - all kinds of additives. They protect the metals in the engine from the damaging effects of ethylene glycol.

Additionally, the composition may include additives to prevent foaming, improve lubricity or to prevent the formation of scale.

Key features of this coolant include:

• the density of the composition averages 1.075 grams per cubic centimeter at 20 degrees Celsius;
• boiling point - 118 degrees Celsius;
• freezing temperature - minus 50 degrees;
• alcohol content - from 50 to 60 percent.

Remember that the basis of the composition of this antifreeze is ethylene glycol. This is a dangerous poison, which is partially neutralized in products with ethyl alcohol. At the same time, antifreeze is dangerous for humans, so keep it out of the reach of children.

Antifreeze G11 and G12: what's the difference?

Let's find out what is the difference between G11 and G12. Which of these products is better to buy, we will tell further. The main distinguishing features are in the composition. Solution G11 (or as it is called "antifreeze") consists of inorganic additive compounds. If you do not go into the details of its characteristics, then a similar composition is intended for use in cars manufactured before 1996. Antifreeze is blue or green, while it is ideal for massive cooling systems due to low heat conductivity.
The main difference between the products in question is the difference in additives. G11 uses inorganic additives and phosphates. The composition forms a thin protective layer on the surface of the part, regardless of the presence or absence of corrosion. The product has a short service life (up to 3 years) and low stability. Residue may remain after application of G11.

It is recommended to replace such antifreeze every 50-70 thousand kilometers. It is compatible with old cars, but pouring the composition into new foreign cars is strictly prohibited. To do this, the industry produces modern models from G12 and above.

Differences G12 and G13

Let's move on to products for new foreign cars and find out what is the difference between antifreeze G13 and G12. G13 products represent a new generation of coolants for foreign cars. A key feature of this fluid (compared to G12) is the replacement of the ethylene glycol base with propylene glycol. There is also a noticeable increase in the content of anti-corrosion additives that act on the source of rust.
An important advantage of the G13 class is an almost unlimited service life if the composition was filled in by the car manufacturer. The difference between G13 and the previously mentioned G12+ is a higher environmental safety due to the accelerated decomposition of propylene glycol. The composition of G13 is orange or yellow, however, different manufacturers may use different colors for their products in this class. Remember that the color of the coolant does not affect its performance!

About mixing antifreeze

The variety of products on the market has resulted in drivers often wondering, is it possible to mix antifreeze g11 and g12 and other classes? There are a number of rules that every driver should be familiar with:

• Mixing G12 and G11 is strictly prohibited due to the use of organic and inorganic additives in these antifreezes.
• You can mix G12 with each other with different colors with the same composition.
• The composition of G12 is compatible with G12+.
• Formulations G12+ through G13 can be added to the G11 product.

It is allowed to add a small tide of distilled water, but only as a last resort. It should be borne in mind that each manufacturer uses its own set of additives. One can only guess about the reaction of such additives in different products, therefore, in order to avoid problems with the engine and cooling system, we recommend adding only an identical brand of antifreeze. To switch to another class of coolant, it is imperative to flush the system.

It is also recommended to make a complete drain if you do not know about the class of the filled composition. The machine may use low quality antifreeze. If you add products of the same grade but of higher quality, a conflict may occur, so it's not worth the risk.
The use of incompatible coolants may cause flaking deposits. They will completely clog the system and, of course, lead to engine failure due to high temperatures. Now you know if g12 and g13 antifreeze can be mixed with G11.

The subtleties of choosing antifreeze

If you have problems choosing antifreeze, first of all, study the manufacturer's recommendations. The specification clearly indicates the brand and class of coolant that should be used in your car model. If the original products are too expensive for you, then you should look at the analogues. The first selection criterion is the novelty of the machine. For cars before 1996, use G11. From 1996 to 2001, a G12 cooler is suitable. In models after 2001, fill in G12 + and G13.
Additionally, when buying, we recommend paying attention to a number of aspects:

• there should not be any precipitation at the bottom of the container;
• the packaging must have a high-quality label, no traces of opening;
• antifreeze does not have a strong odor;
• buy products with a pH value of 7.4-7.5;
• The value of the item must be in line with the market value.

Among the products, there are several already established manufacturers. HEPU has an almost impeccable reputation. The company produces high-quality coolants with a wide range of additives. An alternative option is to take products from Febi. In stores, you can buy formulations from Felix and the domestic manufacturer Lukoil.
Before buying, be sure to read all the markings on the label, as the color of the composition does not always characterize its class. It is recommended to regularly check the color saturation of the antifreeze in the car. A change in color indicates that the liquid has lost its properties, and therefore requires replacement. Knowing the intricacies of choosing a coolant makes the purchase meaningful, safe and targeted.

It differs from ordinary water in that it will never freeze in frost and will not lead to corrosion of the metal walls of the engine and radiator during the entire service life. Today we will talk about G11 and G12 antifreezes, find out what their difference is and whether they can be mixed with each other.

Stability is the key to quality

Antifreeze G11 can rightly be called Antifreeze. The thing is that it is antifreeze that is a complete analogue of foreign G11 antifreeze and completely repeats all its properties. Such a coolant is based on nothing more than ethylene glycol. This substance, synthesized on the basis of ordinary alcohol, has several important properties.

Firstly, it will not freeze even at a record -40 degrees Celsius. In addition, ethylene glycol provides excellent engine protection from boiling: at +120 degrees, the liquid still does not boil and does not begin to evaporate from the engine cooling system.

Another, no less important, component of G11 antifreeze is a dye. Typically, coolant of this standard is green. However, some foreign manufacturers deliberately use yellow, green and red additives. This contributes to the fact that in the company's product line, each liquid has its own shade, and the buyer will never confuse liquids of different standards with each other.

And another important feature of G11 antifreeze is its ability to resist corrosion and rusting of the walls of the internal combustion engine and radiator. Thanks to a system of certain additives, such a coolant acts on the entire surface of the metal with which it has to come into contact. Some semblance of an anti-corrosion coating is created, which does not allow moisture to act on the metal for a sufficiently long time.

Commitment to innovation

G11 standard coolant can be called a real old-timer in the automotive fluid market. However, as time goes by, engines become more powerful and have more and more impressive potential. In this regard, a more advanced cooling system is also required, including a coolant that constantly circulates through it.

In this regard, the G12 standard coolant appeared on the market. G12 antifreeze, unlike its predecessor, has a similar composition, but some differences are still present.

G12 is still based on ethylene glycol. This substance is always invariably included in the composition, since it best performs all its functions in controlling the temperature of an internal combustion engine. The dye is also one of the main components, but most often it has a red or yellow color.

The difference between G12 and an older standard liquid lies in the composition and principle of action of anti-corrosion and auxiliary additives. Recall that Tosol's principle is to completely cover the metal walls with an anti-corrosion film.

In the case of G12, on the contrary, all additives act exclusively locally. In other words, additives independently “find” lesions in which the metal has already begun to corrode. Additives are concentrated around the affected area and carry out its enhanced protection, preventing moisture from causing subsequent destruction of the engine and radiator.

sore point

Often, owners have to mix antifreezes of various standards. So, in some cases, it is necessary to mix in case of emergency breakdowns along the way, whether it is a coolant leak or more serious malfunctions. In other cases, it is necessary to mix due to the reluctance of the owners to spend money on a large canister of a new “cooler” and the desire to save a decent amount of money.

For all these reasons, the question of whether it is possible to mix G11 and G12 coolants is still quite acute.

To answer the question of whether it is still possible to mix liquids with each other, recall the previous section of the article. It pointed out that the biggest difference between the G11 and G12 standards is that here the additives work on different principles.

For this reason, the question comes down to whether it is possible to mix additives of different types? The fact is that the filled antifreeze of the old standard evenly covers the walls of the radiator. The additives of the new will not be able to concentrate around the centers of corrosion, and their properties will be reduced to nothing. Therefore, the answer to the question of whether it is possible to mix liquids of different standards remains negative. It would be best not to change the standard of the liquid poured into the tank, and thereby save a considerable amount of money.

Summing up

So is it worth it to combine liquids of different standards with each other? In no case. To maintain the proper condition of the cooling system, the coolant standard should always remain that recommended by the manufacturer. Changing the fluid to another variety will lead to a loss of anti-corrosion properties and possible damage to metal makers, which is fraught with costly repairs and unpleasant consequences for the car and its owner.
