Additives for oils: reviews. All kinds of additives for motor oil

Any self-respecting motorist at least once in his life thought about the mixtures that are added to the oil to improve its properties. In order to understand what oil additives are, you first need to understand how combustible-lubricating materials are important to your machine.

Physics of engine wear

All motor systems without exception are subject to wear as a result of friction, which occurs during the operation of the entire mechanism. The temperature rises, and this leads to the incandescence of metal parts, of which the working part of any mechanism consists. Eventually, destruction occurs.

As a rule, the valves and pistons of the internal combustion engine are the most affected. In order to reduce wear, the design provides an oil circuit: a closed and hermetic system in which the lubricant is located. Under pressure, it runs through the system, enveloping and cooling all rubbing and moving engine mechanisms.

Mineral oil

Conditionally it is possible to divide the oils into two main categories, which are most often used in a modern car. The first group is mineral lubricants. Most often, this oil has a high viscosity. Specialists recommend using them in older engines with carburetor injection system, as well as on diesel units.

The use of this type of oil is also determined by the frequency of operation of the main shafts of the engine. If the design assumes that the main working process is not associated with high revolutions, the temperature regimes to which the engine systems are exposed are rather low. Consequently, the lubricating material must have an increased viscosity and ductility. Drivers with experience argue that to improve these properties should use additives in gear oil.

Synthetic Oils

The second group is synthetic oils, which are used in modern engines with injection fuel injection. They are used in high-speed motors, where metal components are subject to critical temperature conditions.

According to experts and motorists, both groups have both advantages and disadvantages. Learning about the use of negative qualities of oils, any average car owner tries to neutralize them to some extent.

Additives in oil - good or evil?

It is to improve the properties of lubricating materials and additives to oils are needed. Let's try to figure out whether they really improve the engine performance or still negatively affect its technical condition. Disputes are conducted from the moment when these mixtures appeared.

To understand the essence of the matter, it is necessary to understand what additives to oils, their varieties and purpose exist. To begin with, I would like to clarify that we will consider those that are used by ordinary car owners, and the reviews we are most often interested in.

The main task of any kinds of additives is not only to improve the quality of the oil, but also to improve the main performance of the engine for the better. Some additives in the oil (reviews of almost all experts confirm this) do have a positive effect on its performance.

Reduce oil consumption

Today, the market offers a fairly large segment of additives. The most common types, about which all users speak and positively respond, are additives in engine oil, designed to reduce its consumption. Very often, when oil piston rings fail, oil consumption increases. It is extremely difficult to combat this phenomenon. As a rule, the final elimination of such a defect can be achieved only by replacing these rings when analyzing the engine.

But even a novice car owner understands that the described procedure is very costly. According to experienced auto mechanics, the easiest way to get rid of oil overruns is to top up it as you use it. However, it also does not optimize your budget. In addition, you have to constantly carry a canister with oil.

Here, and come to the aid of viscous additives to oils, designed to reduce the consumption of lubricating component. This is due to an increase in the viscosity of the liquid.

At the same time, motorists note the fact that when the engine is running in the summer this type of additives, which produces each plant of oils and additives, can cause quite significant damage due to high ambient temperatures.

Additives change the properties of the oil

Quite a serious problem is the so-called "wear" effect of the oil in relation to the metal parts of the engine. In other words, sometimes the composition of the liquid changes so much that it spoils its ingredients with metal.

This can be avoided by using a second type of additive: anti-wear. As a result of adding them to the engine a special protective film is formed, designed to protect metal parts from excessive friction. There are many conflicting opinions about the use of such an additive in the oil. Reviews of opponents of its application boil down to the fact that, like in the case of a viscous type, the chemical elements that make up the additive significantly affect the initial formula of motor oil. With prolonged operation, this leads to the destruction of the main elements of the motor.

Oxidation of oil

It is impossible not to note yet another problem related to the prolonged use of motor oil. As a result of possible leakage of the system, the oil oxidizes with time. If you do not pay attention to it, then we get all the same change in chemical composition.

To avoid this, experts recommend additives in gear oil, which are called antioxidant. These compounds are added to prevent the occurrence of chemical reactions associated with the primary oxidation processes. It is believed that the use of antioxidant additives significantly extends life to motor oil.

But, according to motorists, the result of using such mixtures is small: "to clear the conscience," as they say. Your oil, even with great technological wear, remains bright. Maybe that's why some car owners add such additives to the engine before selling their car , essentially saving on oil replacement.

Detergents

Quite a common type of additives in oil are detergents or detergents (Novokuibyshevsky plant of oils and additives produce them in a wide range). Their main purpose is to prevent the deposition of harmful impurities on those parts of the engine that are subjected to the strongest thermal effects (for example, such as cylinder grooves). According to experts, such additives have a positive effect on the internal surfaces of the engine, protecting them from the appearance of pollution and resinous deposits.

These impurities are successfully used in cars with high mileage (precisely because of the qualities listed above). But professionals emphasize that, as a rule, these additives do not have prophylactic properties. And do not add them to the new aggregates.

Disperse additives

As a result of the use of various impurities, by-products are sometimes formed in the form of solid resins and dirt. For their cupping and removal, dispersed antifriction additives exist in the oil.

The use of such additives is desirable only in old power units. The engine is corroded. Particularly from this suffer closed metal surfaces located inside. But because of the similarity of the main properties of the effect with anti-wear mixtures, such additives are used extremely rarely.

Mineral oil additives

If all types of additives for motor oil listed above are universal, the next one is intended solely for mineral oil based motor lubricants. These are antifreeze additives designed to maintain the fluidity of mineral oils under low temperature conditions (from -15 ° C to -45 ° C). Quite a large demand in the market of oil mixtures use extreme pressure additives: they ensure the operation of mechanisms under heavy loads. The principle of their action is to reduce the torque of friction of the metal surfaces of the engine by increasing the sliding properties of the lubricant.

This type of additive is actively used by motorists in pre-sale preparation. There is an opinion that when demonstrating the car, it is the sharp and long pressing of the accelerator that produces a positive impression on the buyer. Fiction is it or not, history is silent, but the use of such additives in forced engines is an indisputable fact that does not require proof.

Antifoam swarms

One can not ignore another type of domes that Novokuibyshevsky plant of oils and additives produces. These are anti-foam additives. They are referred to as detergents, and they serve to eliminate the unpleasant consequences of using more powerful mixtures. The usual detergent additive, in addition to a possible chemical change in the composition of the oil, also acts on the lubricant in approximately the same way as soap on water, that is, there is the possibility of foaming. According to auto mechanics, antifoam additives should be used only when visually detecting changes in the composition of the oil.

The question of the use of additives for oil, each car enthusiast should decide for himself, because their use can be equally good, and badly affect the performance of your car.
