Lukoil brand oils are very popular among domestic motorists. The main advantage of these lubricants is their attractive price. The compositions are made in Russia, so there are simply no import duties and additional margins. At the same time, many drivers also note the fact that the lubricants of this brand in terms of their technical characteristics are in no way inferior to analogues from large international manufacturers. That is why many motorists in central Russia give their preference to Lukoil Lux 10W 40 oil.

A few words about the manufacturer

Lukoil is one of the largest oil and gas companies in Russia. The company is engaged in the extraction, transportation and processing of hydrocarbons. The presence of its own raw material base had a positive impact on the quality of brand lubricants. In addition, the company is actively introducing new production technologies. Product reliability is confirmed by international certificates of conformity ISO 9001 and ISO 9002.

Nature oil

Oil "Lukoil Lux 10W 40" - semi-synthetic. The products of fractional distillation of oil that have passed through the hydrotreating process are used as a kind of base. It is possible to improve the performance of the lubricant through the active use of a complex of alloying additives. It is they who expand the operational capabilities of this oil.

Seasonality

The Society of Automotive Engineers (SAE) classifies this product as an all-weather product. Oil "Lukoil Lux 10W 40" can be used both in summer and in winter. The minimum temperature at which the pump is able to distribute the composition throughout the system and deliver it to the parts of the power plant is -25 degrees Celsius. At the same time, a safe cold start of the engine can be carried out at -15 degrees. The specified oil is not suitable for regions with severe climatic conditions.

For which engines

The specified oil is applicable to gasoline and diesel power plants. It can be used even on large trucks. The oil is compatible with engines equipped with catalytic converters and turbocharging.

A couple of words about additives

To improve the efficiency of the lubricant, the manufacturer actively uses a variety of alloying additives. These substances improve the technical characteristics of "Lukoil Lux 10W40". To modify the properties, the brand uses viscosity additives, friction modifiers, detergents, antioxidant and anti-corrosion additives.

Viscosity additives

The use of such substances helps to maintain the viscosity of the lubricant in the widest temperature range. The mechanism of action of such additives is quite simple. These substances are polymeric compounds of hydrocarbons with a large number of monomers. Macromolecules of viscous additives have a certain thermal activity. For example, when the temperature decreases, these substances coil into a spiral, which allows the oil to maintain the desired viscosity.

When heating increases, the reverse process occurs. At the same time, the sizes of macromolecules in Lukoil Lux 10W 40 oil are much smaller than in compositions with a different low-temperature viscosity index (0W or 5W).

Friction modifiers

The presented type of lubricant protects engine parts from premature wear. This became possible due to the active use of friction modifiers. Molybdenum organic compounds create a thin, inseparable film on the surface of parts, which reduces the friction of parts relative to each other. At the same time, the efficiency of the power plant also increases, and the machine consumes less fuel. On average, fuel consumption for every 100 km of run is reduced by 5%. Yes, the presented figure looks insignificant, but in the context of constantly rising prices for diesel fuel and gasoline, it cannot be ignored either.

Detergents

Oil "Lukoil Lux Turbo Diesel 10W 40" is ideal for diesel and gasoline engines. The fact is that during production, the proportion of detergent additives was increased in the composition of the oil. Detergents dissolve soot accumulations and convert them into a colloidal state. They prevent further precipitation of carbon deposits. Compounds of magnesium, calcium and some other alkaline earth metals are absorbed on the surface of the soot particles and eliminate the risk of their sticking to each other. Carbon deposits in the engine occur due to sulfur compounds contained in gasoline and diesel fuel. With the help of detergents, it is possible to restore engine power, reduce vibration and engine knock.

Antioxidant additives

The composition of "Lukoil Lux 10W 40" is also distinguished by an extended service life. Oil must be changed after 9 thousand kilometers. A similar effect was achieved with the help of the active use of antioxidant additives. Oil components are exposed to atmospheric oxygen radicals. These active compounds oxidize organics, which changes the chemical composition of the lubricant and reduces its basic performance by several times. In this semi-synthetic from Lukoil, the manufacturer added a large amount of aromatic amines and various phenol derivatives. Substances trap air oxygen radicals and inhibit further oxidation reactions.

Anti-corrosion additives

The specified type of engine oil is excellent, especially for older power plants. The problem of engines of this type is the corrosion of parts made from various non-ferrous alloys. In particular, connecting rod bushings and crankshaft bearing shells are subject to excessive corrosion. Compounds of phosphorus, sulfur and chlorine create a strong and acid-resistant film on the surface, which prevents further oxidative processes.

Comparison with another oil of similar viscosity

Drivers often compare this composition with Zic 10W 40. In this case, Lukoil products are noticeably inferior to Zic lubricants. The composition from the domestic brand has a lower curing temperature (-32 and - 37 degrees Celsius, respectively). The composition of Zic 10W 40 is fully synthetic. In this case, various polyalphaolefins are used as the basis. An extended package of additives is also used in the mixture. That is, the final properties of Zic oil are somewhat better than those of Lukoil Lux 10W 40. For example, the replacement interval is 14,000 km.

Driver Reviews

Composition "Lukoil Lux 10W 40" won a lot of positive feedback from motorists. Drivers note a decrease in vibration and engine knock. The pluses include some fuel efficiency of the oil.
