This is an all-season product, which can be used in frost to -25 ºС. In summer, the temperature should not rise above 40 ° C. In such conditions, the lubricant "Rosneft" will be able to provide a high degree of motor protection.
The agent can be used in both petrol anddiesel engines. And the formula, which is different oil, is designed for new engines. Gasoline engines should be 2001-2003 of release. At the same time, the oil contributes to a significant extension of the life of the oil.
The tool is also intended for diesel engines with a turbine, the year of manufacture is higher than 1990.
For severe climatic conditions of our country this means is ideal. It complies with the ACEA A3 / B3 standard, which is used in Europe.
Specifications
The technical characteristics of Rosneft 10w-40 oil are determined by an independent expertise at a high level. They do not differ much from analogues of domestic production.
The kinematic viscosity at 100 ° C is14-16.3 mm² / s. The critical pour point is -33 ° C. This indicator completely corresponds to the requirements put forward to the declared class of viscosity.
The flash point is somewhat inferior to the analogs.It is 205 ºС. Sulfate ash content is 1.5% (corresponds to the norm). Mechanical impurities after the testing were found 0.015%. The density of the medium is quite high. It reaches 900 kg / m³. The results obtained in the course of independent research confirmed the possibility of using the funds in cars of JSC AvtoVAZ, as well as some foreign companies.
Benefits
Oil "Rosneft 10w-40" (semisynthetic),the characteristics of which have been investigated by independent expertise, is characterized by a number of positive qualities. It should be noted that this is an all-season product. It can be used for a wide range of temperatures in different climatic zones. Even with sudden changes in temperature and severe frost, the engine will work fully.
The creators of the representedfeatures of Russian roads, local gasoline and climatic conditions. Thanks to this, it was possible to create an oil that ensures the engine starts in a strong frost. In the heat, a thin film covering the rubbing elements is not torn, the lubricant does not flow into the crankcase completely.
When the load on the engineto form a deposit. Oil "Rosneft Maximum" can prevent the formation of soot at various engine speeds. If the car moves along the roads of a large city, it often costs in traffic jams, this tool will be able to maintain the integrity of the parts even in these conditions. It is when driving on a megapolis that the motor is loaded with the greatest load.
Features of operation
Reviews of the oil "Rosneft 10w-40" (semisynthetic)provide experts on the results of research. Experts argue that the lubricant of domestic production guarantees high-quality engine protection against wear. This is achieved by instantaneous penetration of the means to all the details of the motor. The optimum viscosity index contributes to the formation of a thin but strong film of oil. It provides a quality sliding of rubbing pairs.
Even when the motor is running at maximum permissiblethe film does not break. At the same time, dry areas on the parts do not appear. In cold weather, the fluid quickly gets to all mechanisms, preventing a "dry" start of the motor.
Also a set of special additives contributes togood cleaning of the engine of carbon. Dirt, soot and fine metal particles are collected from the surfaces of the mechanism and kept for a long time in a suspended state. Also, the agent prevents corrosion on the metallic components of the system.
Expert Reviews
Motor oil "Rosneft 10w-40", reviews aboutwhich is provided by experts, belongs to the class of medium varieties of lubricants. It is in many respects not inferior to domestic and even some foreign analogues.
However, the oil presented does not correspondhigh European standards and environmental standards. Domestic oils are produced in accordance with the requirements established in the Russian Federation. The norms of environmental indicators in our country are somewhat lower. Therefore, Rosneft lubricants are used exclusively by drivers of our country.
The standards established in our country forproduction of consumables for cars are completely satisfied with the formula of the presented oil. It provides stable operation of the motor with a small increase in power. The pressure must be constant at the same time.
Forgery
Oil "Rosneft 10w-40" (semisynthetic) canbe licensed and counterfeit. In the first case, the liquid inside the canister meets all standards and requirements. Lubricant protects the engine system from wear and tear, provides an easy start even in frost, perfectly cleans the mechanism.
Today, cases of fake Rosneft oil are not uncommon.Such oil does not pass standardization, does not meet the established requirements. Therefore, filling such a substance with the engine of your car, drivers can observe a lot of negative consequences.
In order not to become a victim of scammers,purchase Rosneft oil from proven implementers, in specialized outlets. In this case it is desirable to require the seller all the relevant documents for lubricants. This will avoid premature engine repairs.
Features of the motor
Oil "Rosneft 10w-40", reviews about whichprovide experts, provides a stable, full-fledged motor work. In the manufacture of this tool a special energy-saving formula is used. This provides a low level of burnout. The oil does not need to be refilled for a long time. The average operating range of the lubricant is 8,000 km. Maximum allowed to ride on oil "Rosneft" up to 10 thousand km.
This reduces fuel consumption.The engine is stable, less noisy. The power of the motor increases. The formula used in the manufacture of the device allows to keep the mechanisms in good condition for a long time.
That the motor does not need to be repaired inthe next few years, you need to carefully study the recommendations of the manufacturer of vehicles. The proper operation of the engine will depend on how correctly the oil is selected.
Negative feedback
In various sources are presented aspositive, and negative feedback about the oil "Rosneft 10w-40". However, there are more positive statements. About 20% of drivers claim that this is a substandard product.
There are opinions that this product formscarbon deposits on the mechanisms of the motor. There is also a high level of oil burnup. At low temperatures, the engine starts up poorly. Some drivers claim that after a similar product they had to make a major overhaul of the system.
Experts say that such reviews canexplained by the acquisition of forgery or misuse of consumables. If the oil consumption is too high, it is possible that the engine is not designed for synthetic lubricant application. In this case, the oil will be more fluid. It can gradually flow through the microcrack system. Therefore, purchasing the oil "Rosneft", you should consider the manufacturer's recommendations. It may be necessary to use exclusively mineral oils.
