Top-10

Antifreeze is an essential composition for a car, but most motorists prefer to use a cheap liquid. However, regardless of the brand of car, it is necessary to use only a high-quality product that will not allow the engine to overheat and not evaporate at the wrong time.

The review presents various brands of antifreeze (including conventional antifreeze), as well as the best concentrates for preparing coolant. The rating is based on the performance characteristics of these products. Also, the opinions of specialists in the maintenance of heat removal systems and direct owners who have experience in the long-term use of antifreeze from a certain company were taken into account.

The best hybrid antifreezes

SINTEC EURO G11

SINTEC EURO G11

It boils at a temperature of +111 degrees Celsius, and gives the first signs of crystallization at around -40 degrees. Owners of cars of such brands as VAZ, GAZ, Daewoo, Kia and other Asian brands, as well as most of the cars manufactured by the VAG concern, can safely use SINTEC EURO G11 for the duration declared by the manufacturer.

Of the positive properties, a large number of lubricating additives can be noted, extending the overall life of the water pump and actively resisting cavitation. There can be no two opinions regarding the cost — it is ideal, especially in comparison with competitors. A worthy example for both used and new vehicles.

FELIX Prolonger-40

FELIX Prolonger-40

The product of the joint work of the Tosol-sintez company and leading Russian institutes for the research and development of technical fluids. Since the vast majority of hybrid antifreezes do not have a long service life, the main emphasis in the creation of FELIX Prolonger -40 was placed precisely on this component. The result of painstaking work was an increase in the replacement period for antifreeze to a maximum of five years. In addition, the coolant is “flavored” with a powerful package of anti-corrosion additives that protect the cooling system from the formation of oxides.

The cost of the composition is low, so it is in high demand on the market, mainly among owners of used cars. However, there is no doubt that it will not harm new cars either, because nothing prevents their owners from filling in the antifreeze of this company. It can be safely used by BMW, Opel, Audi (there is a specification), as well as in Daewoo cars, some Kia models and other popular brands, including domestic VAZs. The green color of the liquid indicates compliance with the VAG G-11 standard. This means that FELIX Prolonger retains its anti-corrosion and coating properties for three years, after which it should be replaced. Adds attractiveness to FELIX Prolonger antifreeze and quite affordable price on the market.

CoolStream Hybrid Extra

CoolStream Hybrid Extra

The absence of harmful components (phosphate and silicate compounds) and highly active additive components have made CoolStream Hybrid Extra antifreeze one of the most popular car consumables on the domestic market. It does not have any damaging effects on seals or rubber pipes. The finished coolant contains a large number of inhibitors that remain highly active under any operating conditions, which prevents the development of oxidative processes in the cooling system.

The use of CoolStream Hybrid Extra green antifreeze is welcome in such cars of the VAZ (LADA), GAZ, Kia, Jilly, Toyota and other brands. In addition, the manufacturer received approvals for VAG, MAN, Iveco, Volvo, and even Rolls Royce concern cars. All this indicates the high performance of the coolant. Nevertheless, the Hybrid Extra price tag is available to the general consumer and is a weighty argument when choosing this product.

The best carboxylate antifreezes

LIQUI MOLY Langzeit Kuhlerfrostschutz GTL 12 Plus

LIQUI MOLY Langzeit Kuhlerfrostschutz GTL 12 Plus

German antifreeze, repeatedly tested and awarded high reviews from car manufacturers. The red color clearly indicates belonging to carboxylate coolants, which are based on organic additives. The freezing point is -40 °C, and this is the strongest side of antifreeze. It boils at around 109 degrees Celsius, which clearly indicates a high content of distillate in the composition.

The positive effect of using this coolant lies in the almost perfect protection of the water pump blades from cavitation, and metal parts from corrosion. It can be used for almost any car, both domestic (VAZ, GAZ, UAZ) and foreign-made (Kia, Deu, Opel, etc.). Many potential buyers may be scared away by the cost, however, the operating parameters of the liquid and the extra long period of operation (up to 6 years), during which the properties of antifreeze remain unchanged, are worth the money spent.

FELIX Carbox-40

FELIX Carbox-40

G-12+ class antifreeze developed by Tosol-sintez. According to the manufacturer, it can be used for all types of engines: boosted, heavily loaded, turbocharged, used in harsh (aggressive) climates, etc. It features a modernized system of local action — a portion of inhibitors is delivered directly to the zone of occurrence of the center of corrosion, neutralizes it and creates a thin (about one tenth of a micron) film of the protective layer.

Regarding the temperature regime, everything is still not bad — the crystallization process proceeds at a temperature of -40 ° C, while boiling begins at around 110 ° C. The cost of antifreeze is low and available to owners of not only domestic cars (VAZ, Chevrolet Niva, etc.). Technical characteristics allow FELIX Carbox to be successfully used even in new foreign cars of Asian (Kia, Hyundai, Chery, Lifan, etc.) and European (cars of VAG, SEAT, FIAT, etc.) origin. The low price and better «survivability» of inhibitors allows antifreeze to maintain its characteristics for five years.

Fenox Green G12

Fenox Green G12

Carboxylate antifreeze Fenox Green G12 is designed for cars whose engine parts are made using ferrous and non-ferrous metals. Like all products of this company, the presented coolant is of the highest quality and has the best antioxidant and anti-corrosion properties. By pouring Fenox Green G12 into the car, its power unit is provided with reliable protection and, as a result, increased performance and durability.

Fenox antifreezes are distinguished by better thermal stability, due to which the action of all components and additives does not stop even at maximum temperature values, in the range from -40 ° C to +110 ° C. Fenox Green G12 is an environmentally friendly product — its composition is completely free of nitrites and phosphates, which negatively affect the environment. This antifreeze is designed for a three-year operating period, and contains a fluorescent additive that makes it easier to identify possible leaks.

The best lobrid antifreezes

Motul Inugel Optimal

Motul Inugel Optimal

If SINTEC is a kind of transitional composition from carboxylate antifreeze to lobrid, then Motul Inugel Optimal can be regarded as a full-fledged lobrid. The transition in temperature is too abrupt. This coolant freezes at a temperature of -37 ° C, and boils at a terrible value of 137 ° C. Neutralizes oxides, breaks down scale, due to which it gives the cooling system a “second life”.

It is also very important that all additives and the concentration of monoethylene glycol in Motul Inugel Optimal are absolutely safe for polymer compounds (plastic and rubber). Such antifreeze is frankly expensive, but it provides a qualitatively different level of protection, for which it is valued by a selective consumer. The action of additives and the durability of the coolant are equally effective throughout all 5 years of operation, and with a gentle use (calm, measured driving and low mileage), this period can be safely extended by a year.

SINTEC UNLIMITED G12++

SINTEC UNLIMITED G12++

Excellent in its characteristics, antifreeze that has successfully passed a set of functional tests. Contains in its composition additives of a new generation, responsible for the comprehensive comprehensive protection of the system. Instead of a directed action on the corrosion site (which is, in fact, the treatment of the «sore»), SINTEC UNLIMITED G12++ forms a protective silicate film interspersed with carbon components. This not only saves metal elements from rust, but also provides protection for the entire life of the fluid.

The freezing point was even lower than stated: at -45 there was only a slight crystallization of antifreeze. This fact allows you to use UNLIMITED in harsh climatic conditions without fear of damage to the pipes of the cooling system. At the same time, the manufacturer announces an antifreeze service life of 5 years, which, given the cost and compliance with the tolerances of Volkswagen, Kamaz, Hyundai, Kia manufacturers, makes it impossible to compete equally with similar products from other brands.

CoolStream A-110

CoolStream A-110

CoolStream A-110 lobrid antifreeze was originally developed for use in Hyundai and Kia cars, however, subsequently received approvals from Mazda, Mitsubishi, Ssangyong and Renault factories, significantly expanded the list of models into which this antifreeze is recommended by the company itself, which produced these cars from the assembly line . Of course, the use of CoolStream A-110 is not limited to this list. The product has become a good choice for many used foreign cars not only of Asian origin.

It is successfully used in European cars, and even more so in Russian cars of the VAZ, Chevrolet and other brands. This antifreeze will help to avoid corrosion, cavitation, gel and foaming inside the cooling system. It effectively removes excess heat and prevents overheating in difficult operating conditions. However, the most devastating blow to competitors was inflicted by the service life: antifreeze will faithfully serve 200 thousand kilometers, but not more than ten years. It is this indicator that does not leave buyers even the slightest doubt when choosing a coolant.

The best concentrated antifreeze

MOBIL Antifreeze Extra

MOBIL Antifreeze Extra

Before pouring this coolant into the vehicle, it must be diluted with deionized water, following the proportions recommended by the manufacturer. This silicate antifreeze is based on ethylene glycol, due to which it creates a strong film on all components of the system, increasing heat removal. The high-quality additives Glysantin G48 from BASF included in its composition provide the best protection of all parts and the most important components of the car cooling system from corrosion and freezing.

Due to the absence of amines and phosphates in the composition of MOBIL Antifreeze Extra antifreeze, the possibility of the formation of harmful deposits is excluded during its use. This coolant is compatible with ferrous and non-ferrous metals as well as aluminum. MOBIL Antifreeze Extra is recommended for use by well-known car manufacturers such as Mercedes-Benz, Opel, BMW, Saab, etc. This antifreeze is able to provide better protection to cylinders, water pumps, radiators, etc. for at least three years.

LIQUI MOLY Kuhlerfrostschutz KFS 2001 Plus G12

LIQUI MOLY Kuhlerfrostschutz KFS 2001 Plus G12

German concentrate approved by global automakers. The temperature range is regulated by the “by eye” method — the company does not give any recommendations on this matter. However, there is verified information that if you fill in Kuhlerfrostschutz KFS 2001 Plus G12 and treated water in a 1 to 1 ratio, you get a standard coolant frost resistance of -40 ° C. For the northern regions, this figure can be increased to -50 ° C by adding 600 ml of deionized water per liter of concentrate. The organic complex present in the composition actively protects the system from corrosion, scale and cavitation, prevents the engine from boiling, regardless of its operating conditions.

Many motorists write that this composition (red) can be mixed with blue antifreeze (of the same manufacturer) G-11. Given all the above features, we can safely say that this product is one of the best concentrates on the domestic market. It is recommended for use in some models by the German VAG. The KFS 2001 Plus G12 does an excellent job with the engines of Asian cars (Hyundai, Kia, Daewoo, Lifan, etc.), and there is nothing to say about the models of domestic VAZ, Chevrolet and others — this durable and reliable antifreeze will significantly improve the performance of Russian auto.

Castrol Radicool NF

Castrol Radicool NF

Hybrid concentrate suitable for use in passenger cars and trucks with diesel and gasoline engines. The replacement interval is more than three years, which is an excellent result for hybrids. Corrosion protection at the level — inorganic additives, coupled with organics, completely neutralize the rust center.

Can be mixed with green antifreeze of any brand, as well as diluted with water in free proportions. In the recommended ratio, the threshold temperatures have the following values: freezing occurs at -35 degrees Celsius, and boiling at +175. An interesting and very worthy «anti-freeze», which is in great demand among domestic consumers. Despite the somewhat aggressive reaction of the concentrate to polymer compounds, its effect on protecting the engine from possible overheating looks like an obvious advantage over many of its closest competitors. However, it is precisely this shortcoming that has become the reason why Castrol Radicool NF occupies the third position in this category.

The best traditional antifreezes (antifreeze)

FELIX Antifreeze -45 °C

FELIX Antifreeze -45 °C

In this category of traditional coolants, FELIX antifreeze is considered the best option to choose from. It is not so expensive that owners cannot afford to pour it into their car. Antifreeze is successfully used in trucks, almost all domestically produced cars, and on the VAZ conveyor it is used as a coolant for new vehicles.

It mixes well with other brands of antifreezes and antifreezes of any category, and in emergency situations, the use of FELIX Antifreeze -45 ° C is the most rational solution, even for modern engines. Despite the blue color of the liquid, according to the VAG classification, this product corresponds to the categories G11 (green) and G12 (red), which makes it possible to safely use it in the car engine cooling system from 2 to 5 years (but not more than 150-200 thousand km) .

OILRIGHT Antifreeze -40 °C

OILRIGHT Antifreeze -40 °C

The base number of antifreeze is 12.9, which means that «OILRIGHT Antifreeze -40 ° C» confidently counteracts oxidative processes in the engine cooling system. The manufacturer recommends this product for use in modern vehicles. Antifreeze of this brand, despite the affordable cost, has an international certificate of conformity. It can be poured into cars manufactured by the VAG concern, and even more so into domestic models of VAZ, GAZ and others.

With a standard service life (2 years), the coolant does not destroy rubber seals and pipes. Working in various modes, «OILRIGHT Antifreeze -40 ° C» does not form scale and gel-like deposits in the system. The boiling point is 109 °C, which is sufficient for reliable heat removal under normal operating conditions.

Alaska Tosol -40 °C

Alaska Tosol -40 °C

This product is one of the most affordable offerings on the market. In fact, this is the strong point of Alaska antifreeze (antifreeze). It really does not freeze at -40 ° C, but it approaches its limit very tightly, turning into a thickened ice porridge, and completely crystallizes already at -41 ° C. For this reason, it should not be poured into vehicles operating in regions with winter temperatures below 35 °C.

At the same time, it has a good alkaline index (ph 8.1) and the best resistance to foaming for such a price. The weak side is considered to be a low boiling point (101 ° C), therefore, the car engine should be operated with this coolant with more caution. Additive inhibitors (there are few of them, but they are present in Alaska Tosol -40 ° C) will begin to break down already at 98 degrees. In the southern regions, it definitely should not be flooded. It is more suitable for a temperate climate and cars, the bulk of the mileage of which occurs on long-distance routes. In any case, this antifreeze is getting better and better than ordinary water, and it does not have a destructive effect on such an element of the system as a water pump for the entire service life. For old VAZ models and foreign cars, it will definitely come in handy.
