The most popular question asked by motorists about coolants is: “Is it possible to mix one antifreeze with another?”. After all, it is often required to add a little antifreeze to the car's cooling system. And the owner, as a rule, has no idea what kind of liquid was originally poured there. At the same time on the shelves of stores is full of cans with antifreezes - all kinds of names, colors, and even made using different technologies. And when mixing dissimilar products in the final mixture, operational properties may be affected, which may lead to a decrease in the resource of the equipment (for example, a water pump).

So we checked the corrosive effects of mixtures of Sintec Multifreeze antifreeze and coolants of all types on different metals. All indicators obtained comply with the requirements of GOST.

A radical approach is to replace the entire coolant as a whole. For buyers of used cars, this is a justified decision: it is not known what kind of liquid is splashing in the cooling system. And if the car is fresh or antifreeze recently changed? Modern liquids are designed for 200, 000-250, 000 km, and it is not advisable to drain them ahead of time.

So how to choose antifreeze? By color? By name? Difficulties are caused by the fact that various manufacturers use four basic technologies in production. And on the shelves are adjacent coolants, called traditional, carboxylate (OAT, organic acid technology), hybrid and lobrid. They can have any color: it is determined not by production technology, but by the added dye. In other words, in order not to harm the car, you need to know exactly what type of antifreeze is poured into the cooling system, and the color of the antifreeze is not always fundamental. But you should not mix one green liquid with another green, not being sure that they are made using the same technology. The most effective way to use antifreeze, according to the “do no harm” principle, promises universal products. So, the #Sintec brand new product - Multifreeze - stands out from the traditional line. Laboratory test results confirm that #Sintec Multifreeze can be used as the main coolant - this will allow in the future not to worry about topping up or replacing the coolant. In addition, #Sintec Multifreeze can be added to the cooling system of any car, no matter what liquid is used in it before. Of course, we are talking only about obviously high-quality products.

The compatibility of #Sintec Multifreeze antifreeze with coolants from other manufacturers is confirmed by comprehensive tests. The product uses the latest additive packages that combine the benefits of carboxylate and silicate antifreeze. This allows you to mix this product with any antifreeze, without fear for the performance of the cooling system. Not only #Sintec Multifreeze itself was tested, but also products obtained as a result of mixing it in proportions 90:10, 10:90 and 50:50 with carboxylate (G12), lobride (G13) and traditional (G11) antifreezes of different colors produced renowned companies in four core technologies. Tests showed the absence of chemical reactions and precipitation when mixed with other products. In addition, the resulting mixtures completely retain the anticorrosive properties of the coolant.

Moreover, in Sintekovskiy Multifreeze, a slower consumption of additives was revealed during operation, which prevent corrosion and do not affect seals. So, you can less often change the coolant. Initially, #Sintec Multifreeze is a clear liquid with a lilac hue. During operation, the color may vary slightly, but this has nothing to do with the quality of the product. The shade is affected by oxidation products and a changing concentration of additives, which is an indicator of normal operation. When mixed with other antifreeze, the final color will depend on the concentration of both liquids. But in any case, the antifreeze will remain transparent, without flakes, sediment, suspended matter. If antifreeze of a different color is dominant, then the color will not become swamp-dirty - Sintec Multifreeze adjusts to the color of the main liquid, slightly changing the shade. A special fluorescent marker has been introduced into its composition, which will help during vehicle maintenance to quickly determine the places of coolant leakage using ultraviolet light.

Trust but check

Statements by the manufacturer regarding compatibility with other fluids are confirmed by laboratory test results. #Sintec Multifreeze was alternately mixed with various types of coolants: carboxylate, hybrid, lobrid and traditional. The resulting mixtures were heated to almost a hundred degrees for a certain time, then placed in a cabinet without access to light for up to two days, and then the interaction of additive packages was analyzed. They were mixed in different proportions, imitating situations when, for example, it is necessary to top up a little (ratio 10:90), or replenish the system due to a burst pipe (50:50), or completely replace antifreeze, but because of the design features of the car some spent fluid remains in hoses or radiators (90:10). Tests showed the absence of stratification, as well as precipitation.

These criteria show the result of the interaction of additive packages when mixing different coolants under conditions close to actual operation. The study confirmed that #Sintec Multifreeze can be mixed with almost any coolant.

In addition, we checked the corrosive effect of the “cocktail” of Sintekovsky Multifreeze and various types of coolants (1: 1 ratio) on the metals of which the engine cooling system is made: copper, aluminum, brass, steel, cast iron (the norm in all cases is no more than 0.1 g / m 2 per day) and solder (the norm is not more than 0.2 g / m 2 per day). The tests were carried out according to GOST 28084. General conclusion: a mixture of Sintekovsky product with all tested samples perfectly protects metals from corrosion, significantly exceeding GOST standards. Those wishing to familiarize themselves with the data in more detail are sent to the table.
