The popularity of Nissan cars is growing year by year. These vehicles are highly reliable and attractively priced. In order for the car engine to last as long as possible, the manufacturer himself recommends using original Nissan 5W40 oils. This composition is designed specifically for these vehicles. Its use allows you to fully unlock the potential of the car.

Manufacturer

The Japanese brand does not have its own production facilities necessary for the manufacture of motor oils. The company entered into an agreement with the French oil and gas consortium Total. It is this company that produces motor oils for the Japanese concern. The brand is engaged in direct production, transportation and processing of hydrocarbons. The French giant pays special attention to the quality of its final products. This is confirmed by the presence of international certificates of conformity ISO and TSI.

For which motors

Nissan 5W40 oil is suitable fordiesel and petrol engines. It can be used in power plants manufactured after 2004. The lubricant is used for turbocharged engines and engines equipped with direct fuel injection.

Season of use

Classification of motor oils according to the season of their use was proposed by the Society of Automotive Engineers of America (SAE). According to this gradation, the presented composition belongs to the category of all-season. It can be used all year round. The minimum temperature at which the pump can pump oil through the system and deliver it to engine parts is -35 degrees Celsius. Safe cold start can be carried out at -25 degrees.

Nature oil

Depending on the manufacturing method, all engine oils are divided into three classes: mineral, semi-synthetic and synthetic. This composition belongs to the latter type. In this case, a mixture of polyalphaolefins is used as the basis. The properties of the composition can be improved thanks to a whole range of alloying additives.

A couple of words about additives

In the manufacture of Nissan 5W40 engine oil, the manufacturer used an extended additive package. These chemical compounds allow you to increase the technical characteristics of the product at times.

Stable viscosity

Nissan 5W40 oil differs from many analogues in stable viscosity indicators in the widest temperature range. This was achieved thanks tothe use of organic polymer compounds. The macromolecules of the presented substances have some thermal activity. When the temperature decreases, they curl up into a spiral, which slightly reduces the viscosity. During heating, the process is reversed.

Cleaning the engine

Nissan 5W40 oil (synthetic) is suitable for engines running on high ash fuels. For example, it can be used in diesel power plants. As is known, the fuel in this case contains a large amount of sulfur compounds. When burned, they form ash, which settles on the internal parts of the power plant. As a result of this negative process, the power of the motor drops significantly, since the effective volume of the internal space decreases. The engine starts knocking. Part of the fuel does not burn, but is immediately discharged into the exhaust system. To prevent the formation of soot deposits, manufacturers have added detergent additives to the oil. In this case, sulfonates of calcium, barium and some other alkaline earth metals are used. These substances are absorbed onto the surface of the ash particles, preventing their coagulation and precipitation. The advantage of Nissan 5W40 oil also lies in the fact that this composition is capable of destroying already formed soot agglomerations. It converts them into a colloidal state and prevents further settling on the surface of engine parts.

Temperature limit

KThe positive characteristics of Nissan 5W40 oil include a low freezing point. This composition goes into a solid phase at -44 degrees Celsius. This effect was achieved thanks to the active use of methacrylic acid copolymers. These substances prevent the crystallization of paraffins, reduce the size of the formed solid particles.

Life extension

Drivers note that the presented composition differs from others in its extended service life. An oil change can be carried out after every 10 thousand kilometers. It was possible to increase the mileage due to the active use of antioxidants. The fact is that air oxygen radicals are able to interact with some components of the oil. They change the chemical composition of the lubricant, which leads to a decrease in performance. To trap radicals in the presented oil, manufacturers added phenols and aromatic amines. These substances inhibit the oxidative process and prevent premature chemical degradation of the oil.

Protecting old engines

One of the main problems of all old engines is corrosion. Rusting is most often exposed to power plant parts made of non-ferrous metal alloys. For example, corrosion can occur on the connecting rod head or crankshaft bearing shell. Especially to protect the power plant from the action of weak organic acids, manufacturers added compounds of phosphorus, sulfur andchlorine. They create a thin durable film of phosphides, sulfides and chlorides on the surface of metals, which inhibits the further corrosion process.

Difficult environments

Riding in the city is a serious test for the engine and engine oil. The fact is that with such a control mode, the driver must constantly accelerate and brake. A sharp increase in the number of revolutions of the power plant can cause the oil to simply churn into foam. Detergents also speed up this process. The presented compounds reduce the surface tension of the oil, which increases the rate of foam formation. To combat this negative effect, the manufacturer added silicon compounds to the lubricant. These substances destroy the air bubbles that occur when the oil is actively agitated.

Friction protection

The positive characteristics of the presented lubricant include good protection of car parts from friction. This effect was achieved thanks to the active use of organic compounds of molybdenum. These substances create a strong, inseparable film on the surface of the parts, which prevents the risk of rubbing and scratches.

Reducing friction automatically leads to an increase in motor efficiency. As a result, it is possible to reduce fuel consumption. On average, this oil reduces fuel consumption by 6%. In the context of constantly rising prices for gasoline and diesel fuel, this figure does not seem insignificant.

A couple of words about the cost

What areoil prices "Nissan 5W40" (synthetic)? The cost of a five-liter canister starts from 1700 rubles. At the same time, some analogues of this composition, for example, TOTAL Quartz 9000 5W40 or ELF Excellium NF 5W40, are more expensive, although they have the same manufacturer. The reduced price for Nissan 5W40 oil is due to an agreement between a Japanese car manufacturer and a French oil and gas consortium.

Reviews

The opinion of the drivers about the presented composition was extremely positive. In reviews of Nissan 5W40 oil, motorists note, first of all, that it allows you to return the power of even old engines. Owners of Nissan brand cars recommend using this lubricant for regions with harsh climatic conditions. The oil provides a reliable and safe engine start even in the most severe frost. The advantages of the mixture include its good fuel efficiency. The use of this composition reduces vibration and engine knock. A similar effect was achieved due to the fact that a variety of detergent additives are actively used in Nissan 5W40 engine oil.
