Japanese-made cars are in high demand among motorists. These vehicles are distinguished by high reliability, attractive design and cost. To extend the life of the engine of these vehicles, the company itself recommends using genuine Nissan oils. For example, the composition of the Nissan 5W40 proved to be excellent. What are the advantages of this lubricant and what are its specifications?

Who is the manufacturer

The Nissan brand itself is not engaged in the manufacture and sale of motor oils. The presented product is produced by the Total consortium. This French oil and gas company has been extracting and processing hydrocarbons since 1924. The full production cycle has significantly improved the quality of the final product. Since 2001, the French brand has entered into a formal partnership agreement with Nissan and engaged in the development and production of motor oils for this company.

Nature oil

Nissan 5W40 composition is categorizedsynthetic. The manufacturer uses various oil hydrocracking products as base oil. At the same time, the company also uses an extended package of additives in the mixture. As a result, it was possible to multiply the performance of the product.

Type of engines

Nissan Motor Oil 5W40 is suitable for four-stroke gasoline and diesel powertrains. The mixture can be used even in engines that meet Euro-5 standards. According to API standards, the mixture is assigned the SM / CF index, which fully confirms the above thesis.

Season of use

Nissan 5W40 oil is an all-weather oil. This is reflected in the 5W40 index. The oil is suitable for use even in regions with very severe and cold winters. The fact is that the lubricant can be pumped through the system to temperatures not lower than -35 degrees Celsius. Safe engine start is carried out at -25 degrees. At lower thermometer readings, the oil density becomes very high, as a result of which the battery may not have enough energy for the first turn of the crankshaft.

Viscosity

Nissan Motor Oil 5W40 is distinguished by the stability of its density over the widest temperature range. This effect was achieved through the use of various polymer compounds in the composition of the mixture. When the temperature decreases, the macromolecules coil into a specific spiral, which reduces the viscosity of the composition. Atan increase in external heating, the reverse process occurs. Macromolecules unwind, density increases.

Cleaning the engine

Soot and soot agglomerations are often collected on the outer surface of power plant parts. Diesel engines are more susceptible to this negative effect. The fact is that the fuel for such units contains a large amount of sulfur compounds. During combustion, they form soot, which settles in the inner chamber. In this case, the properties of the power plant deteriorate. For example, soot reduces the effective displacement of the engine, resulting in a sharp drop in power. Fuel consumption also increases proportionally. Part of the fuel is not oxidized, but immediately goes into the exhaust system of the vehicle. Compounds of barium, magnesium and some other metals are used as detergent additives. These substances destroy the formed soot agglomerations, keep carbon particles in the oil volume and prevent their further coagulation.

For old engines

The problem of all old gasoline and diesel engines is the presence of corrosive processes that occur on parts made of non-ferrous alloys. For example, rust often forms on crankshaft bearing shells, connecting rod bushings. The presented composition is able to slow down this negative process. To do this, compounds containing bound sulfide sulfur were added to the mixture. They create a thin film on the surface of the alloy, which prevents the contact of metals with an aggressive environment.

Stabilityproperties

Anti-oxidant additives in Nissan 5W40 oil improve lubricant life. The fact is that oxygen radicals in the air can oxidize some components of the oil. Naturally, with a change in the chemical structure, the technical characteristics of the product also fall. To minimize this negative effect, aromatic amines and phenol derivatives were added to the oil composition. These substances trap free oxygen radicals in the air and prevent their further reaction with lubricant components. Oil properties remain stable throughout its life.

Depressants

The pour point of Nissan Motor Oil 5W40 is -44 degrees Celsius. The company's chemists managed to achieve such impressive performance thanks to the active use of various pour point depressants. These substances reduce the rate of crystallization of paraffins, which makes it possible to significantly expand the final temperature range of the oil applicability. The company's chemists use various polymeric compounds of methacrylic acid as pour point depressants.

Protecting the engine in difficult driving conditions

City driving puts more stress on the engine than highway driving. The driver is forced to constantly accelerate and brake. Changes in the number of revolutions cause the oil to churn into foam. A certain contribution is made by various detergent additives. The fact is that they reduce the surface tension of the oil. It is possible to overcome the foaming process due to the introduction oflubricant composition of silicon compounds. They destroy air bubbles that occur during the rotation of the crankshaft and engine pistons. The presented composition perfectly protects the engine even under the most difficult operating conditions.

Economy

Attractive price for Nissan 5W40 and extended drain interval (13,000 km) make the purchase of this composition extremely profitable. The advantage lies in the fact that the presented version of the lubricant is characterized by the presence of a large number of additives that reduce the friction of engine parts against each other. As a result, the efficiency of the engine increases and fuel consumption decreases. Compared to analogues from other brands, fuel consumption can be reduced by about 5%. Manufacturers use metal acetates and borates, molybdenum disulfide as friction modifiers.

A couple of words about the cost

The price of Nissan 5W40 engine oil (5L) starts from 2100 rubles. At the same time, the presented type of lubricant simply has no analogues. This composition was developed exclusively for Nissan engines. An advanced additive package allows you to fully reveal all the capabilities of the power plant.

How to choose

Good performance and attractive cost created another problem. The fact is that these oils have often been counterfeited. And often, instead of the original composition, cheaper mineral types of lubricants or conventional mining are poured into the canister. Distinguish the original Nissan 5W40 from a fakepossible through a number of measures.

First, you need to carefully analyze the container in which the oil itself is sold. There must be no gaps between the cover and the fixing ring. The quality of the seam made to solder the canister should also be analyzed. It should not have any external defects (curvature, excessive bulge).

Secondly, you need to pay attention to the quality of printing. The font on the label must be even and legible. All security holograms must be present on the label.

Thirdly, at the slightest suspicion of counterfeiting, the seller must be requested to have quality certificates. The purchase itself is best made in large stores of the corresponding direction.

Driver opinions

Reviews about the Nissan 5W40 from drivers are extremely positive. Motorists note that the presented oil allows you to increase the power of the power plant and reduce fuel consumption. Grease does not burn. The drivers also attributed the extended replacement interval to the pluses.
