Rosneft motor oils - synthetics or semi-synthetic? Motor oils "Rosneft": Overview of the best oil Rosneft maximum 5W40 characteristics

It cannot be said that Rosneft oils have flawless technical characteristics. But it is worth considering the price segment in which the products of this manufacturer are located. Thanks to good qualities, a wide range and affordable price, Rosneft are in great demand. Also, the company in 2012 signed an agreement with the Russian company AvtoVAZ, and now its products are used in the cars of cars that come out from under the concern conveyor. So, today, many drivers use lubricant of this brand, even without guessing it.

A few words about the company

Rosneft is the leader of the domestic oil industry, as well as one of the largest companies in the world. The pH-lubricant's subsidiary of this giant is engaged in manufacturing and selling oils for passenger and commercial vehicles and even for industrial equipment.

In the ranking of additives in Russia, Rosneft ranks first, produces more than 300 product names for cars. If you take the whole market of lubricants of Russia, then the share of Rosneft on it will be 19%, which is quite a lot. In total, there are 5 factories in Russia.

Brand oil is a product of the company's joint development, employees of scientific enterprises and car manufacturers. The main "Rosneft", which is shipped to the market: Premium synthetics, mineral oil "Optimum", semi-synthetic "maximum", as well as the flushing composition "Express". Note that the company includes special databases of additives, thanks to which the product retains its characteristics during the entire service life. All oils meet the requirements of European standards and are adapted for different working conditions. The company is serious enough to the production process and quality control, ranging from oil production and ending with the sale of the final product to consumers.

Overview of Rosneft oils

As we said, there are 4 categories of oils that are supplied to the market: Premium, Maximum, Express, Optimum. Each category includes its specific products with unique features, and they are suitable for different types engines.

Premium.

This category includes only one Rosneft oil - synthetics with a class of viscosity 5W40. The additive package includes a package, thanks to which this product is ideal for use in the VAZ brand cars. Also these oils can also be used in the engines of European manufacturers. Supplied this product On the market in the canister from 1 to 4 liters.

Benefits this oil Rosneft:

1. It has a high viscosity index, retains its lubricating properties even at low outdoor temperatures. Therefore, it can be operated in winter time, providing easy engine start at negative temperatures.
2. Provides high level The reliability of the motor operation, creating the necessary oil film under any operating conditions.
3. It struggles with deposits on the details of the motor during the entire period of operation, which increases the engine resource.
4. Protects the friction pairs from wear and is stable to the shift.
5. It has high compatibility with engines that operate on gasoline with high sulfur content.
6. Differs low consumption due to lack of evaporation.
7. It has high oxidation resistance.

Note that this product is appropriate to use in new engines. The category "Premium" is intended for use in highly affiliated most modern motorsworking on diesel fuel or gasoline, as well as turbocharged. Equally efficiently oil shows itself in domestic cars, as well as in models of European and American manufacturers.

Oil "Rosneft" Maximum

The Maximum line is characterized by lower cost and base. This includes several products. of different viscosity. Also, the Maximum line includes lubricants, the base of which is semi-synthetic. Rosneft oils of this category are represented by two products - with a viscosity of 5W40 and 10W40.

Maximum 5W40.

This is all-season universal oil on a semi-synthetic basis. It includes a balanced package of world manufacturers additives, thanks to which the product received anti-corrosion properties and thermal stability, antioxidant and dispersing properties.

The product is intended for use in gasoline engines with turbocharged, as well as in diesel power plants Domestic and foreign production, in the instructions of which the possibility of using oils of this level of quality is prescribed. Note that the 5W40 viscosity oil is ideal for use in Russia, because the temperature range of the product is wide: then -30 to +35 degrees.

Reviews Rosneft oil 5W40 gets mainly positive. In particular, buyers allocate such advantages:

1. Affordable price compared to products from other oils with the same viscosity.
2. Economical consumption. The oil does not go to the avgar, and from the replacement to replace its level almost does not change.
3. Easy engine launch even in severe frosts.
4. Support for optimal pressure even with strong loads and high motor turnover.

Also, the manufacturer declares that the oil prevents deposits on the parts of the motor, but the usual owner can hardly check it hardly.

Maximum 10W40

It is also all-season semi-synthetic oil With a special package of additives. Its main difference from the previous one is the viscosity of 10W40. This means that the product is more dense. Like the previous lubricant in the ruler, this can also be used in summer and winter. True, the temperature range of work is different. If the oil with a viscosity of 5W40 can operate at a temperature of -30 degrees, then 10W40 thickens at more high temperatures - In the area of \u200b\u200b-20 degrees.

Below your attention is a graph of viscosity of the oils with the indication of their temperature ranges of operation.

For all other parameters, Maximum 5W40 oil is almost no different from Maximum 10W40. Both products have anticorrosive properties, thermal stability and approved AvtoVAZ OJSC.

Category Optimal

This category includes mineral base oils. Their composition includes multifunctional additives. These products are intended for all-season use, and it is appropriate to fill in carburetor enginesas well as in injector motorsworking on diesel fuel, gas and gasoline.

Rosneft oils are supplied to the market. Optimal categories with the following viscosity parameters:

1. 10W30.
2. 10w40.
3. 15W40.

All of them can boast of increased antioxidant stability, ensuring protection against engine corrosion and all sorts of sediments. When working in their temperature ranges Products will provide normal motor launch.

Rosneft flushing oil Express

This product is also made on a mineral base and contains a large package of effective detergent additives. It is intended for quick flushing of gasoline and diesel engines from deposits that are necessarily formed during the work. The use of the Express product is recommended when changing the oil, as well as after too long use of lubrication, for prophylactic motors cleaning.

The process of using this "washing":

1. Warm motor to operating temperature.
2. Fully merge the spent oil.
3. Pour an Express oil. The volume must be standard. The entire oil system must be filled.
4. Run Motor on idling And let him work for 15 minutes.
5. Merge waste fluid. Pay attention to the color. If the oil was very darkened over these 15 minutes, then this indicates the effective cleaning of the engine.
6. Change oil filter And fill out fresh oil.

The correct choice of engine oil is not only the key to a large engine resource, but also by 3-5% increases the power and pickup engine, and also reduces fuel consumption. Therefore, often drivers ask themselves questions, which is better:

• synthetics or semi-synthetic;
• 5W40 or 10W40;
• Rosneft or any imported oil?

In this article, we will respond to the first two questions, and the third detail disassembled in the article - Rosneft motor oils - comparison with other oils. There we have proven that russian oil Under the brand "Rosneft" is not inferior to many overseas oils of the same class, and all the stories about poor-quality oils of Rosneft are generated incorrect use These products.

How oil kills engine

Most of the car owners know that the oil lubricates the details, cools the pistons and performs other important functions, but few understand why good oil Suddenly turns into a motor killer.

After all, from this misunderstanding and grow myths about the low quality of one or another oil. Even the best oil recommended by the car manufacturer, after rebirth kills it in the same way as the cheapest oil that gets cleaning the old work.

What is oil? Despite the fact that it is visually perceived by a homogeneous liquid, it is not quite so. Basic oil obtained from oil (mineral), gas (synthetic) and mixtures of both products (semi-synthetic) has mediocre characteristics. In addition, each type basic oil Fully different flaws. For example, mineral oil is well lubricated only at room temperature, and a small heating sharply reduces the lubrication ability.

The synthetic oil is much resistant when heated or cooling, but its lubrication is much lower. The semi-synthetic is a cross between synthetics and mineral water, so in some extent it is inherent in the drawbacks of both source products.

To turn mediocre lubrication into high-quality oil, add different additives that change its properties to it. Despite the fact that each manufacturer uses its own set of additives, here are those that are included in any oil:

• detergent;
• stabilizing;
• antioxidative;
• contamilated;
• antipid;
• adjustable viscosity at high temperatures.

That is, the oil is a very complex substance from many components. Part of the additives is mixed with the source product, forming a homogeneous solution. Another part makes an oil suspension - a liquid in which small solid fragments float. In ideal conditions, the service life of oil is 10-15 thousand kilometers. From the first kilometer, changes are starting in oil affecting both the basic base and additives. First, these changes are invisible, but approximately 2-3 thousand kilometers part of the additive stops acting. This is due to:

• high temperature;
• carter gases;
• metal chips;
• high pressure.

On new engines, where the breakthrough of crankcase gases is minimal, these processes occur closer to 5 thousand kilometers. When the oil deprives parts of the additives (they fall into the sediment or simply lose their properties), its characteristics are changing and the oil ceases to match the motor and operation mode.

After that, the oil degradation process begins to accelerate and 10 thousand kilometers it loses half of its characteristics. What does it say about? It is possible to ride for some time on such oil, but carefully and slowly, without sharp accelerations and high loads. To 15 thousand kilometers, the substance that is in the engine is not much different from the initial mineral or synthetic oil, that is, is very mediocre lubricant.

To change such a development of events has not yet been able to any manufacturer of motors or oils. But we described the processes that occur in ideal conditions, in reality, everything is much worse. After 10 thousand kilometers of the mileage, the most expensive premium oil is no different from the cheapest, that is, no qualitative engine lubrication can be speech. It is like that of the domestic fuel, broken roads and the inability of most drivers to ride. After all, the right ride is not only safety on the road, but also the optimal mode of operation of all car units.

Therefore, on russian roads Those who really take care of the motor, change the oil every 5 thousand kilometers, if you have to go to heavy conditions, then every 3-4 thousand. With this approach, the engine is equally protected equally and lubricated both branded and most domestic oils, including Rosneft.

Selection of oil by engine

To choose the right oil, you need to understand - under what conditions the motor works. New engine It has minimal gaps between driving parts and minimum breakthrough of crankcase gases. Therefore, it requires the maximum fluid, which formulated at high temperatures, is thin, but effectively lubricating film. As the engine wear is wear, the gap between the logging parts is becoming increasingly unfinished fuel and traffic fumes all stronger break through piston rings, turning into crankcase gases. Therefore, for worn engines, more dense or less fluid oil is required, otherwise it will not be able to form a film on rubbing surfaces due to a large clearance.

Therefore, the viscosity directly depends on the engine state, this refers to any type of oil. In addition, the engines that put on the cars in the mid-80s need less viscous oil than those put in the 21st century. The above accuracy of manufacturing rubbing parts, less gaps, and therefore, less viscous oil. Therefore, the oil is selected:

1. First determine the viscosity of SAE - 30 or 40 . Viscosity 30 is well suited for new or capital repaired engines in which all gaps are minimal and not broken. In addition, the viscosity 30 is good only for machines that are exploited in calm conditions, without sharp accelerations and heavy loads. The viscosity 40 for those motors where compression is below the rate of 1.5-2 atmosphere. If the compression is lower than 2 atmospheres, it does not matter which oil to fill, the engine will still not work normally. Also, the viscosity 40 is more suitable for motors working in severe conditions - mountainous areas or frequent sharp accelerations and braking.
2. Then determineaPI viscosity, given the year of the car. It is undesirable to pour into the engine an oil that does not correspond to this parameter, because it will be too thick and will not be able to flow to rubbing items in sufficient quantities or too liquid. Liquid oil flows from rubbing parts, leaving a thin layer that does not provide reliable protection.
3. The oil is selected byair temperature - Summer oil in winter will be too thick, because of what each attempt to start the engine will turn into torture for the driver and the motor. The driver will be angry, because the car does not start immediately, and the driving parts of the engine will spin "on dry", because too thick oil will not create a film of the desired thickness.
4. Only after that choose betweensemi-synthetic and synthetics . There is a simple rule - if the motor works in comfortable modes, then there is no difference between the types of oil. Such a motor works equally well on synthetics or mineral. The worse the engine mode, the stronger there should be a skew toward the synthetic oil, up to a complete refusal of the mineral base. That is, completely synthetic oil. In addition, the numbers before the viscosity indicator indicate the cold resistance index. That is, the oil with an index 5w will provide a normal start at temperatures up to minus 30 degrees, and with a 10W index at a temperature of minus 25 degrees.
5. Lastly, choose oil manufacturer. We have already proven that Rosneft motor oils are no longer inferior to their analogues on SAE and API from other manufacturers. It is clear that it is impossible to compare Mineral oil Rosneft 5W40 with synthetic shell oil Helix 5W30, even if they, by some miracle, were one class by SAE. Moreover, it is impossible to compare oils with different class SAE, because they are made for various motors and operating conditions. But within the same class by SAE and API Oil Rosneft is not inferior to foreign counterparts.

Rosneft oil - what is better: synthetics or semi-synthetic

Often in the stores car owners ask a question that is better, 5W40 synthetic or 10w 40 semi-synthetic from Rosneft? In fact, this is the root of the wrong question, because both oils are good, but for their situations. After all, such a semi-synthetic is good engines operating in medium and heavy modes, for example:

• taxi;
• ambulance cars;
• courier cars.

This oil is well suited for those who sometimes have to squeeze out of the motor. Everything possible, spinning to maximum revolutions or driving through a complex highy relief, but mostly operating the car in a calm mode. If the driver prefers a very fast and aggressive ride, the synthetic is preferable for it. Especially if it goes in the same way and in the mountainous area.

In addition to low price Rosneft Maximum Motor Oil is favorably featured by universality. It can be used throughout the year and on gasoline and on diesel engines. Moreover, the specifications of this lubricant provide the possibility of applying on modern DVS with increased specific power.

Universality is provided mainly due to the broad functionality of the "base", containing both synthetic and mineral oils. Such a composition has a mass gain. First of all, this is an improved lubricity at low ambient temperatures and stability. technical characteristics at high.

Another feature of this lubricant is the use of a packet of additives balanced in its characteristics. With it, almost all operational properties are improved - from resistance to oxidation to preventing the formation of contaminants on metal surfaces.
