Like any other mechanism, the internal combustion engine has the property of wearing out. This is especially true for domestic cars. However, there is a way to increase the life of the engine and all its elements. It consists not only in the timely replacement of oil, but also in the use of specialized additives. How do additives work to restore the engine? What are they special about? About all this and much more - later in this article.

Characteristic

The additive is a substance that is added to the fuel or to lubricants in order to improve the performance and technical characteristics of the car. To date, there are many types of these funds. Among them, it should be noted additives with anti-smoke, detergent, anti-wear, antioxidant and reducing properties.

Most of these substances are aimed at reducing car fuel consumption and restoring its previous dynamic and power performance.

In addition, additives are usually distinguished according to the method of application. In total, there are 2 types of products that are added to fuel or engine oil.

The first type of additives perfectly copes with the decrease in the consumption of gasoline. Due to their special composition, they improve the quality of fuel, its octane number, and also remove excess condensate from the tank. Upon entering the combustion chamber, the mixture purifies the exhaust valves, the walls of the chamber, and all the elements of the fuel system.

Additives for engine restoration are most often poured into engine oil. By their properties, they perfectly cope with the accumulated dirt, carbon deposits and tarry deposits inside the engine. Also, these additives reduce the frictional force of the motor parts, make the oily film more durable and wear-resistant, which increases the productivity of the car. Many manufacturers recommend adding such substances to the engine for lapping parts in new vehicles. They also perfectly restore the layer of cermets on the worn out parts of the motor. All this makes the engine work more coordinated and increases the life of the cylinder-piston group.

Composition

The recovery additive for the compression of the engine, which is added to the engine oil, can be made from different components. Such substances can be divided into several groups:

• Funds on a metal-clad basis. When such additives penetrate into the places of friction, they create an additional cladding layer. The latter is able to equalize all the defects that were formed on the surface of the metal parts due to the wear of the piston group and crankshaft bearings.
• Means based on mineral powders. Due to their properties, they perfectly restore the cermet layer on the motor parts, while producing a micro-grinding of the steel surfaces.
• Means based on polyesters and chloroparaffins. Such additives are less popular than the two previous types. But under conditions of high pressure and temperatures, these substances can convert all deposits into an ionic state. In simple words, they act like a flushing oil, removing all the carbon deposits and dirt from the surface of the ICE elements.

Principle of operation

How do additives work for gasoline engines? The principle of their work is as follows. When they get into the engine oil, such additives form a cermet liquid crystal. With increasing loads on the engine (increase in temperature and pressure), this component acts as a welding machine, thereby "sealing" all the holes, irregularities and cracks. As a result of the function of the additive, the surface of the rubbing elements is covered with a protective layer of ceramics and metal particles. Based on the results of the research, due to the presence of various metals (nickel, platinum, tantalum and cobalt) in the composition of these substances, the rubbing sections are doped to a depth of up to 200 μm.

Differences of reducing additives from those that are in oils

Probably, each of us heard that engine oils come from the factory with a full set of useful additives. This is so loud and proudly declare the world's producers. However, companies do not recommend mixing oil with other components. This, ostensibly, can change the composition of the lubricating fluid. But, according to experts, there is nothing in common between reducing additives and those that go along with motor oil. Let's see why.

The fact is that the additives claimed by the oil producers are compounds that form the properties of the oil as such. What does it mean? Oil is one continuous additive. But as manufacturers of lubricating materials hide this unprofitable, they continue to advertise their products, which "already has a balanced package of additives."

The manufacturers of additives themselves call their goods tribo-composition, that is, protective-reducing substances. And mixing it with oil is completely safe and even beneficial for the engine. Additive - this is only the people's name tribosostava.

How effective are the additives for restoring the engine?

Recently, one of the autoportals posted the result of the action of one eminent additive on the engine of the VAZ-2110. Prior to the experiment, special equipment was used to measure the power and compression of the engine. The data were as follows: the motor developed a power of 61 horsepower, while the compression level was 8 kgf / cm ² . After 2 thousand of mileage, the measurements were taken off again. The results were impressive. The maximum power of the engine increased by 20 percent (up to 74 horsepower), and the compression ratio in the cylinders increased from 8 to 12 kgf / cm ² .

Also, the equipment showed that the friction losses decreased by 60 percent. Thus, the additives for engine recovery do give the result.

Additive for the engine "XADO" - reviews of drivers

"XADO" is a domestic manufacturer of lubricants, which in more than 20 years of its existence has gained popularity not only in the CIS, but also abroad. Should I trust this company? There is no single answer to this question. There are many reviews, both positive and negative. Having analyzed a large number of opinions, we can draw the following conclusion.

Supporters of XADO products are those who actually used one or another type of additives. In such reviews, there is at least a partial description and analysis of the product used, as well as an impression of its use.

The opponents are those who did not use XADO products for the most part and left their opinions based on emotions. Specific information such reviews do not contain, only an imaginary and vague idea of the product.

What is noteworthy, the additive for the XADO engine, as users note, almost never harms. That is, it is the most safe and effective product that you can trust.

Among the main advantages of additives "XADO" should emphasize their quality of action. Motorists emphasize that even after 200-300 thousand kilometers the engine works properly, does not touch or smoke.

Among the shortcomings, many drivers have noted an excessively high price for the product. Indeed, XADO makes very expensive additives for the engine. The price for one ten-gallon tube of the substance is about 300 rubles. For a complete recovery course, you need to buy at least 5 such bottles, which will cost 1500 rubles.

"Suprotec"

Above we did not consider all the additives for the engine. The drivers' comments also emphasize the effectiveness of the "Suprotec" facility. This brand has long been known to car enthusiasts for its high-quality and safe products for the recovery of internal combustion engines. Also, "Suprotec" is engaged in the production of tribo-components for gearboxes and reducers.

Judging by the reviews, this additive not only repairs microcracks, but also reduces fuel consumption. As practice shows, the economy of the car increases by 10-15 percent. However, it concerns only those that are poured into the tank (that is, not a protective additive for the engine). "Suprotec" (drivers' reviews also note this moment) perfectly copes with its task both in summer and in winter. Therefore, it is able to make a worthy competition for the products of the domestic brand XADO.

But this is not all the pluses that the additive for the engine "Suprotec" differs. The reviews also emphasize the low market price of the product. The cost of one tube of additive "Suprotec" of 90 milliliters is 1500 rubles. This is almost 2 times lower than that of a similar tribo-composition from XADO.

LIQUI MOLY

Very good additives for the diesel engine (and gasoline too) is made by the German company "Liquvi Moli". It is engaged in the production of universal products, which are aimed at reducing the overall fuel consumption and restoring the metal surfaces of the cylinder-piston engine group. The composition of the additive fully meets all modern requirements and standards, which allows it to be used for most cars in the world market.

Additive LIQUI MOLY. Capabilities

1. Increases the octane number of gasoline to 6 units. That is, when mixed with AI-92 fuel will meet the standard AI-98.

2. Prevents the risk of engine detonation.

3. Increases the power and performance of the car.

4. Reduces the risk of burning candle.

5. Reduces the level of toxicity of exhaust gases.

The cost of the additive "Liquid Moli" is very democratic. For a three hundred-milliliter bottle you only need to pay 400 rubles.

What's better?

Proceeding from all of the above, the best additives for the engine are "Liqui Moli" and "Suprotec". By their effectiveness, they are almost inferior to products from XADO, while they cost less. However, it is up to you to decide which brand to choose. All three presented companies have a good reputation in the market and offer their customers really high-quality products. The difference is only in price.

Conclusion

So, we have found out what features protective-reduction additives for engines possess. Finally, we note that when choosing tribosostavov should not believe the myths about their harm to the car. International studies have shown that protective and recovery products do correspond to those properties that manufacturers claim.

But motor oils, in contrast, often remain ineffective and can only reduce the level of friction between the walls of the cylinders due to a thin film. The reducing compounds can remove the deposits and microcracks that were formed due to the prolonged operation of the vehicle without external interference. And they remain effective all year round.
