A little about the manufacturer
stood at the origins of the development of the oil refining industry, now it is a leader in the domestic market and is one of the largest companies in the world. One of the subsidiaries produces oils for passenger cars, commercial vehicles and industrial equipment.
Now the company occupies the first position in the ranking; its assortment includes about 300 types of products for cars. Of the entire lubricants market in the Russian Federation, Rosneft’s share is 19% - this is a significant figure. There are 5 factories in Russia.
The company's oils are developed jointly by employees of scientific enterprises and car manufacturers. The composition includes special types of additives that ensure the preservation of oil characteristics throughout the entire recommended period of use. Rosneft ensures strict control of products at all stages - from oil production to product packaging and safe delivery to consumers. Oils are suitable for different working conditions and have European quality certificates.
Oil additives
The positive properties of base oils are enhanced by multifunctional additives:
- viscous and depressor. Allow Rosneft 5w40 synthetic and semi-synthetic oil to have a constant viscosity, provide extreme temperature conditions from -30° to +40° C;
- anti-corrosion and anti-oxidation. They slow down the rate of oxide formation and the accumulation of carbon deposits on the surface of the piston group. Protects parts made of non-ferrous metal alloys. For example: oil pump drive bushings having a copper-graphite composition, camshaft liners coated with bronze and others;
- anti-wear. The active elements formed as a result of chemical modification create a thin, constantly renewed film of iron sulfides and chlorides. This prevents fatigue crumbling, the formation of scoring, and helps reduce friction;
- anti-foaming and detergents (detergents). Reduces foaming. Reduces carbon deposits and varnish formation;
- dispersants (dispersants). Prevents the adhesion and enlargement of particles of insoluble contaminants.
Their total presence reaches up to 20%. Precise selection of combined additives increases oil service life.
General information about oil Rosneft Premium 5W-40 4 l
Synthetic oil, as the manufacturer claims, but in fact it is hydrocracking and even possibly mixed with mineral water. Can be used in gasoline and diesel engines of domestic and imported cars, suitable for off-road models, minibuses. Not suitable for turbocharged engines and systems with particulate filters. Quite good performance characteristics for an oil in this price category. The additive package is selected to provide detergent, wear and corrosion protection properties.
It has API approvals only, but a whole list of compliances from automakers. The SM oil class somewhat narrows the range of its use; it is not suitable for the latest engines. But it is adapted to the difficult Russian conditions.

Types of oils Rosneft 5w40
Depending on the composition, lubricants are presented in the following range:
- Rosneft premium 5w 40.
- Rosneft maximum 5w 40.
They are made on the basis of mineral oil (produced from oil) and synthetic oil (derived from gas); semi-synthetics are obtained by mixing two components in certain proportions.
Synthetic Premium 5w 40
Synthetics Rosneft premium 5w40 is produced by chemical synthesis. The structural composition of base substances changes, and molecular hydrocarbon compounds are redirected.
Aligned chains acquire increased thermal stability and chemical inertness. The product has API SM/CF approval.
Advantages:
- provides easy starting, maintaining fluidity at low temperatures;
- saves fuel by reducing warm-up time, reducing friction force and rapid distribution among components and parts;
- protects the engine from overheating and corrosion, forming an optimal lubricating film thickness;
- does not require frequent replacement.
The lubricant is poured into gasoline and diesel engines, but it should be noted that Rosneft 5w40 synthetics have low compatibility with engines equipped with turbines.

Test results
The oil is quite liquid, closer to the lower limit of the standard. So it will be quite economical. Stability under load is not bad - high viscosity index and flash. Can be used with loads. Very good cleaning properties, the gap between acid and alkali is also quite decent. The standard mileage goes off without loss of properties. A very good ratio with acid, especially for domestic oil. A package of additives was used here, no worse than what is poured into imported analogues. As for sulfur, the oil is also quite clean. Not bad low-temperature performance, even quite good for 5W oil. There is also NOACK in the analysis, if you take this indicator and the flash point, you can draw conclusions about the oil base - it is quite high quality. A lot of anti-wear additives, although there is no molybdenum in the composition, will protect well.
Advantages
- Maintains fluidity throughout the entire run.
- High quality and clean base.
- Can be used in foreign car engines.
- Low oil consumption.
- The most environmentally friendly among other domestic products.
Flaws
- Cold start not lower than -20 degrees.
- Relatively unstable under load.
- No fuel economy.
Brief Product Description

How to spot a fake
The manufacturer has developed its own anti-counterfeit system, which includes the following points:
- The lid is black with a three-dimensional manufacturer's logo.
- There is a locking ring on the lid itself, which should click noticeably when opening.
- When you remove the cover, you can find a soldered protective foil underneath it.
- On the side of the canister there is a transparent strip with measuring divisions, through which the liquid level in the container is clearly visible.
- At the bottom of the canister there is another protective logo.
In addition to these points, you should not forget about the general recommendations in identifying a fake. First of all, this is the quality of the plastic - if it is too soft, deformed and has an unpleasant odor, the product is not licensed.
