The service life of a car engine directly depends on the reliability of engine oil and the frequency of its replacement. Of course, all motorists know this thesis. That is why they are so careful in choosing the right composition. In reviews of Liquid Moli 5W40 oil, owners note, first of all, the stability of the properties of the lubricant throughout its entire service life.

A few words about the brand

The company was founded in 1955 in Germany. Initially, the brand focused on the production and development of various additives for engines. A little later, motor oils also appeared on sale. Now the company's products are sold in more than 100 countries around the world. And the demand for it is constantly growing. The brand closely follows the latest trends in the automotive industry and offers compounds that are ideal for the most modern engines.

Nature oil

Experts in the reviews of "Liquid Moli 5W40" declare that this100% synthetic oil. As a basis, manufacturers took a mixture of polyalphaolefins. To modify the properties of the lubricant, various alloying additives were added to the composition.

For which engines

This engine oil is suitable for turbocharged and conventional engines. It can be poured into gasoline and diesel engines. At the same time, the composition itself is recommended by some car manufacturers. For example, it is advised to use it for warranty and post-warranty service by such companies as BMW, VW. Liquid Moli 5W40 oil in the Polo sedan from Volkswagen is applicable even for old cars manufactured in 2010.

Seasonality

According to the classification of the American Society of Automotive Engineers (SAE), this oil is classified as an all-weather oil. The required flow rates are maintained even in the most severe frost. It is possible to pump oil through the system and ensure its flow to all parts of the power plant at temperatures of -35 degrees Celsius. At the same time, it will be possible to safely start the engine at -25 degrees.

A little about additives

To improve the technical characteristics of the oil, manufacturers add various alloying additives to it. They expand the properties of the lubricant, make it more reliable. Liquid Moli 5W40 oil, in comparison with other compounds, is distinguished by an expanded package of additives, which makes it possible to improve the characteristics of this mixture several times.

Stable fluidity

Oil viscosity is one of the main properties of a lubricant. Especially to improve this indicator, the company's chemists introduced polymeric hydrocarbon compounds into the composition of the presented product. They are characterized by high thermal activity. As the temperature decreases, the macromolecules of the substance coil into a spiral, which leads to some decrease in the density of the composition. When heated, the reverse process occurs. The helix of the macromolecule unfolds, which increases the viscosity.

Low pour point

In reviews of Liquid Moli 5W40 oil, drivers also note the low pour point of the presented composition. The fact is that this oil passes into the solid phase at -42 degrees Celsius. Manufacturers have been able to achieve such impressive results thanks to the active use of pour point depressants. In this case, methacrylic acid copolymers are used. These compounds prevent paraffin crystallization and reduce the rate of paraffin precipitation.

Operation of a car on bad fuel

Oil "Liqui Moli 5W40" (synthetic) in a diesel fits almost perfectly. The problem with all engines of this type is that the quality of the fuel does not stand up to criticism. Diesel fuel has a high ash content. This is true for some brands of gasoline. Ash is produced by the combustion of sulfur compounds that are part of the fuel. Soot particles stick together and precipitate. This reduces the real effective volumeengine, power drops.

Part of the fuel does not burn in the inner chamber, but immediately goes into the exhaust system. It also negatively affects the environment. It was possible to eliminate the presented problem thanks to the compounds of magnesium, barium and calcium. The molecules of these substances are fixed on the soot particles and prevent them from sticking together. Detergent additives are able to destroy the agglomerations of old soot, transferring them into a colloidal state. That is why many owners of old cars give such flattering reviews about Liquid Moli 5W40 oil. Drivers note that using this composition, it was possible to significantly reduce the knock of the engine.

Durability

Positive feedback about the Liquid Moli 5W40 oil (synthetics) is also given in matters of lubricant durability. The specified lubricant has an extended drain interval. For example, it can cover up to 13 thousand kilometers. This indicator was achieved thanks to the active use of antioxidants. The fact is that oxygen radicals in the air are able to react with various components of the oil.

Often, because of this, weak organic acids are even formed, which can initiate the corrosion process on metal parts of the engine. The physical properties of the lubricant also change. To prevent these undesirable consequences, aromatic amines and phenol derivatives were introduced into the composition of the oil. These substances trap atmospheric oxygen radicals and reduce the risk of oxidation of other components.lubricants.

When driving in difficult conditions

Using a car in an urban environment is considered difficult. The fact is that frequent changes in engine speed cause foaming of the oil. The situation is worsened by the use of a large number of different detergent additives. These compounds reduce the surface tension of the lubricant. To eliminate this negative effect, manufacturers introduced silicon compounds into the oil. They destroy the air bubbles that arise during mixing of the substance and prevent excessive foam formation. As a result, the oil is best distributed over the surface of the parts of the power plant.

Corrosion protection

Besides soot deposits, another problem with all older engines is corrosion. The parts of the power plant made of non-ferrous alloys are exposed to rusting. For example, this phenomenon often occurs on the crankshaft bearing tabs, connecting rod bushings. In reviews of Liquid Moli 5W40 oil, drivers note that this composition can significantly slow down the indicated negative process.

The fact is that various compounds of sulfur, phosphorus and chlorine are additionally added to the lubricant. They create numerous phosphides, chlorides and sulfides on the metal surface. Such a film is not subject to destruction from friction or exposure to organic acids. As a result, it is possible to prevent the further spread of corrosive processes.

Reduce friction

In reviews ofoil "Liqui Moli Moligen 5W40" drivers note that the use of this composition allows you to postpone the repair of the power plant and reduce fuel consumption. Engine efficiency is increased due to the fact that the manufacturer actively uses a variety of friction modifiers. In this case, organic compounds of molybdenum, borates of other metals are used. These substances create a thin, inseparable film on the metal surface, which prevents the contact of the surfaces and their rapid wear. Reduced friction also saves on fuel. On average, consumption is reduced by 8%.

Replacement options

The presented composition is widely used among motorists. Therefore, the brand expanded the line and released some other formulations. Liquid Moli Optimal 5W40 oil has gained popularity. Reviews about this lubricant of the company are extremely positive. The abundance of detergent additives makes it almost ideal for cars with a diesel engine. The problem is that there is no interchangeability between mixtures. With a decrease in the volume of lubricant, adding another composition, even from the same brand, is highly discouraged.
