Oil Lukoil Lux 5W40 is a Russian semi-synthetic of the highest quality, which is recommended for use in both gasoline and diesel engines of a variety of passenger cars, trucks and construction equipment. In temperate climates it can be used.

7 reasons why you need to switch to semi-synthetic Lukoil Lux 5W40

1. Oil has a very low price. If we compare foreign oils with similar characteristics and compliance, then Lukoil Lux 5W40 will cost about 2 times less. The fact is that the product is made from its own base oil produced in Russia. This significantly reduces the cost of oil. But the additives that are added to the oil are produced abroad and purchased only from leading oil companies. That is why you should not worry about the quality of the oil based on the price. A low price does not mean that the product is of low quality.

2. As mentioned above, the oil is based on only high-quality base oils.

3. Additive package contained in the oil Lukoil Lux 5W40, are produced abroad only by leading oil companies.

4. Focus specifically on the Russian climate with cold winters. And also work on fuel of even the poorest quality. Do you agree that Lukoil is closely familiar with the harsh Russian realities?

5. Excellent viscosity-temperature properties, which allow this oil to be used even at extremely low temperatures without harm to the engine. The oil also performed well at high operating engine temperatures. ensures very easy engine starting and rapid supply of lubricant to all rubbing parts, while completely eliminating “oil starvation” with all the resulting unpleasant consequences. At high engine operating temperatures, it fully retains its properties and performance characteristics.

6. Protects the engine due to the fluid containing unique anti-wear additives of the latest generation.

7. First-class detergent additives that ensure engine cleanliness and prevent the formation of soot and other harmful deposits.

In which cars can Lukoil Lux 5W40 semi-synthetic be used?

Scope of application of semi-synthetics Lukoil Lux 5W-40 not limited to passenger cars only. Here you can add minibuses, minivans, crossovers. SUVs, light commercial vehicles, trucks, construction equipment, etc. Excellent for use in gasoline and diesel engines equipped with turbocharging, intercooler, and multi-valve systems. The product is compatible with the latest exhaust gas aftertreatment systems, with all types of catalysts, but is not recommended for use in exhaust systems equipped with a DPF. Allowed for use in vehicles operating under constant loads (working in Start-Stop mode, towing other equipment, traveling with a trailer, extended oil change service intervals, etc.). Suitable for use over a wide range of operating temperatures.

Test Lukoil Lux 5W40 for heating or “frying the oil”

The heating test of this product showed very good results. The oil was heated in the flask to a temperature of +220 degrees C for about 15 minutes, then the flask was turned over to the other side and the procedure was repeated. After the flask has cooled, the amount of deposits can be assessed. The conditions are not ideal, and the engine oil itself never heats up to that temperature. But the test was done at the highest possible temperature. And if the oil passes this test, then there will be no deposits in the engine. In our test, small soot and deposits appeared on the walls of the flask. This does not mean the oil is of poor quality, but it does indicate that the oil should be changed more often.

Lukoil Lux 5W40 engine oil belongs to the highest class, as it meets all requirements for performance properties and is licensed according to API SN/CF, ACEA A3/B4 classifications, and also has recommendations and approvals from many European automakers. Its perfectly balanced composition ensures good low-temperature properties. LUKOIL oil has many different advantages, including resistance to high-sulfur gasoline, fuel economy and lack of waste, but, of course, it is not without its drawbacks, in particular the content of oxidation products and low environmental friendliness.

Such oil can be poured into the engines of both modern domestic cars and the engines of middle-class foreign cars, but for premium and sports cars it is still better to choose something more expensive and of better quality, since there is no need to save on MM in such cases.

The article reviews:

Technical characteristics of MM Lukoil 5W-40

The duration of trouble-free operation of the engine largely depends on the quality and properties of the lubricating motor fluid. Lukoil 5W40 helps reduce the friction force of parts of a running engine, and also prevents the appearance of deposits (since soot particles are held in suspension and do not settle), which allows not only to reduce their wear, but also to maintain engine power.

Although all the declared characteristics of the main indicators are overestimated, they are within the limits of acceptable values, this is evidenced by an independent analysis of MM, and the declared quality is quite acceptable.

As a result of the tests:

• kinematic viscosity at 100 °C – 12.38 mm²/s -14.5 mm²/s;
• viscosity index – 150 -172;
• flash point in an open crucible – 231 °C;
• pour point – 41 °C;
• the increase in power relative to the base oil is 2.75%, and fuel consumption is -7.8%;
• alkaline number – 8.57 mg KOH/g.

With such technical characteristics, Lukoil Lux synthetic oil 5W-40 API SN/CF ACEA A3/B4 is capable of withstanding a load of 1097 N, with a wear rate of 0.3 mm. Reliable protection of engine parts under extreme loads is achieved through the formation of a stable oil film.

Good lubricating properties were achieved thanks to the innovative New Formula complex, which provides engine protection over a wide temperature range. Additives from foreign manufacturers allow you to cover the surface of parts with a durable oil film. Each of the constituent elements of this formula is activated depending on certain conditions. This is why, thanks to reduced friction, engine efficiency increases and fuel savings are achieved, and the noise level is reduced.

Scope of application of Lukoil 5w40 oil:

• in gasoline and diesel engines of passenger cars;
• in turbocharged cars and even highly accelerated sports cars;
• in car engines that operate under difficult operating conditions at temperatures from -40 to +50 degrees Celsius;
• in the engines of most foreign cars during service, both during warranty and post-warranty lines (for which there are recommendations).

Lukoil oil is more resistant to our high-sulfur gasoline.



Lukoil Lux 5w 40 API SN/CF has received the approval of such companies as: Volkswagen, BMW, Mercedes, Renault and even Porsche, since it meets almost all modern requirements. “Almost” because there is a high sulfur content (0.41%) and unimportant environmental indicators. Therefore, even though the Lukoil motor oil labeling contains approvals for BMW Longlife-01, MB 229.5, Porsche A40, Volkswagen VW 502 00 / 505 00, Renault RN 0700/0710, in European countries the use of this oil is not encouraged, since the requirements there are very high environmental requirements.

A high alkalinity number indicates that the motor will be clean, but an increased amount of sulfur indicates low environmental friendliness.

The main disadvantages of Lukoil 5W-40 oil

As a result of testing Lukoil Luxe Synthetic 5W-40 oil on the VO-4 installation, it was found that the lubricating fluid has a high photometric coefficient, since a large amount of dissolved and suspended oxidation products appeared in the oil. At the same time, the change in viscosity and base number is not large. This indicates average production of a polymer thickener and a multifunctional additive package.

So, Lukoil motor oil is characterized by:

• high content of oxidation products;
• quite high level of pollution;
• insufficient environmental performance.

Price for Lukoil oil (synthetic) 5W40 SN/CF

As for the price of Lukoil 5W40 SN/CF synthetic oil, it is quite affordable for most car owners. To make sure of this, we suggest comparing the cost of a liter and a 4-liter canister relative to other foreign brands.

For example, we consider the Moscow region - here the price is 1 liter. Lukoil Lux Synthetics (cat. no. 207464) costs about 300 rubles, and 4 liters (207465) of this oil will cost 1000 rubles. at a rate of 64 rubles. for one dollar. But the same popular one costs at least 1800 rubles. for a 4-liter canister, and such brands as Zik, Motul and Liqui Molly are even more expensive.

However, the relatively low price of Lukoil Luxe Synthetic 5W-40 does not mean that it is less profitable to counterfeit, because it is the most popular. Therefore, you can also find low-quality products on the market.

Distinctive features of the original Lukoil 5W40 oil

How to distinguish counterfeit Lukoil oils

Since there are quite a lot of scammers who want to profit from the regular needs of car owners by counterfeiting consumables, including Lukoil 5W-40 oil, the Lukoil company has developed several degrees of protection for its oils, and has published distinctive features by which one can distinguish the counterfeit of their oils on on its official website.

Five degrees of Lukoil oil protection:

1. The two-color canister lid is soldered from red and gold plastic. At the bottom of the lid there is a ring that comes off when opened.
2. Under the lid, the neck is additionally covered with foil, which is not just glued, but must be soldered.
3. The manufacturer also claims that the walls of the canister are made of three layers of plastic and when the protective foil is torn off, the multilayer structure should be visible (the layers have different colors). This method makes counterfeiting even more difficult, since this cannot be done with conventional equipment.
4. The labels on the sides of the Lukoil oil canister are not paper, but fused into the canister, so they cannot be torn off and re-glued.
5. - laser. On the back side there must be information about the production date and batch number.

As you can see, the company took care not only of the quality of the product itself, but also of its authenticity, and in order to make our review of Lukoil 5W 40 motor oil even more complete, we suggest that you read the reviews of car owners who have used or are using this lubricant to service their engine. cars.

November 7, 2016

Every day the number of types of automotive products is only increasing. New brands appear, advanced technologies are introduced, and innovations are developed. Among the wide variety of goods, it is difficult for the average person - a car owner - to respond in a timely manner to changes in market conditions. Often, there is a certain passivity on the part of the manufacturer in terms of information content, conveying complete information to the consumer. The population receives only a portion of the total, which does not allow for a complete picture of the product. In such cases, the active participation of sales consultants in retail outlets is important. So that with each request, the client can receive the most complete information about the product, make comparisons, and study printed booklets.

Based on the title of the article, it is obvious that we will talk about automotive fluids. Using the example of Lukoil Luxury motor oil, we will consider in detail the product as it should be “conveyed” to the consumer. Along the way, we will conduct a comparative analysis of other types and brands according to various criteria. We will touch upon the topic of replacing fluids, timing, quality and quantity.

A little history of the Lukoil brand

Back in 1991, by order of the Government of the Russian Federation, the oil company PJSC LUKOIL was created. Not many people know that the abbreviation comes from the capital letters of the cities - oil fields: Langepas, Urai, Kogalym. The word “oil”, translated from English, is familiar to everyone - oil. The main directions of economic activity are exploration, production, processing of oil products, supply to markets. The geography of sales goes far beyond the country. The products are actively consumed in Turkey, Europe, and the USA. Quality and reliability are the main keys to the company’s success.

Outstanding representative of Lukoil

Among the wide variety of Lukoil brand oils, special attention should be paid to 5w40. The liquid belongs to the synthetic class. According to the international classification, it meets all the necessary requirements of API SN/CF, ACEA A3/B4. “Approval” for use was given by such automobile concerns as Volkswagen, Mercedes, Audi, Ford, Seat, Renault, BMW. As you can see, the “green light” is not limited to just one country; the territory covers many countries. It is recommended to use 5w40 synthetics in gasoline and diesel power units. Budget and premium cars. The only limitation is its use in high-speed internal combustion engines in racing and track sports cars. Lukoil has developed a separate type of oil for this category. The chemical formula is strictly “tailored” to the needs of sports vehicles.

Indicators and characteristics

For many car owners, it is important to know what the fluid consists of, what components are included, and what it is intended for. The higher quality the product is poured into the motor, the longer it will last without repair. What can surprise synthetics:

Types of power units: basic, turbocharged, biturbo, forced. Transport operating under critical temperature conditions from - 40°C to + 55°C. The highlight of the product is its adaptation to fuels with high sulfur content. Gasoline in the Russian Federation has exactly these indicators, unfortunately. 5w40 lubricant is recommended for use at the stage of warranty and post-warranty maintenance of domestic and imported cars. Thanks to the presence of alkali as a component, the engine parts will always be clean, without deposits. Despite the majority of “for”, there are also not so many:

• the sulfur indicator has been increased, which means there is no need to talk about the environmental friendliness of the 5th, 6th class. Only the fourth;
• The alkali also does not please the general background, despite cleaning the engine.

Price policy

Universal accessibility is the main rule of the brand. The average Lukoil Lux 1 liter will be 300 rubles, a 4 liter canister will cost the owner 1000, 1100 rubles. Depending on the region, the price varies. Foreign analogues are much more expensive. For example, Castrol, Liqui Moly, Shell, at least 1,750 rubles/4 liters.

An increase in demand gives rise to a thirst for profit on the part of satellites. Despite the active implementation of security systems by the manufacturer, fraudsters are “conquering” new heights of protection every day. Passivity and inaction will lead to a complete depreciation of the brand and withdrawal from the consumer market. More details about protection are described directly on the Lukoil website. Everyone has the opportunity to read the information freely. But let's focus on the main points:

Please note: Once the buyer has a minimal understanding of motor oil, the product coding should be explained to him. Types of lubricating fluids: synthetic, semi-synthetic, mineral base. The difference between representatives is in cost, composition, molecular formula, protective properties. Despite such diversity, classification occurs according to a single formula, according to the standards of the international SAE API (Society of Automotive Engineers) system. In other words, an indicator of viscosity at different temperatures. Today, the vast majority of oils are of a mixed type - all-season. The first digital designation indicates the low-temperature viscosity indicator. The letter W is for filling in winter. The second group of numbers is data on the maximum permissible temperature (hot period). Markings without letters indicate a purely summer version of the lubricant. In our version, 5w40 is an all-season option for cars.

Temperature

• 0: up to minus 35°C;
• 5: - 30°C;
• 10: - 25°C;
• 15: - 20°C;
• 20: - 15°C.

Second digital indicator:

• 30: +25°С;
• 40: + 35°C;
• 50: + 45°C;
• 60: +50°С.

Thus, 5w40 is recommended to be used year-round at temperatures not exceeding +40°C and not below -30°C. Simple and clear.

In addition to the alphanumeric symbol, there is a marking with the inscriptions SJ or CF. According to the American Petroleum Institute "API", this is a distinction based on the type of power unit: gasoline and diesel, respectively. The second symbol will indicate the specific year of manufacture of the car and the installed turbine.

• SC (gasoline) / CB (Lukoil luxury diesel): car production until 1964;
• SD/CC: before 1968;
• SE/CD: before 1972;
• SF/CE: 1988;
• SG/CF: 1994;
• SH/CG-4: 1996;
• SJ/CH-4: 2000 g;
• SL/CI-4: 2003;
• SM/CI-4 plus: since 2004.

Varieties

In addition to 5w40 synthetics, the brand offers many types: semi-synthetics, mineral base for trucks and construction equipment. There are special designs for heavy-duty mining dump trucks. Engineers have not forgotten about motorcycle equipment and two-stroke engines. Wide selection of products for mowers, self-propelled units, and household equipment.

It is recommended to purchase Lukoil Lux only at specialized, certified points of sale. The full list can be found on the manufacturer’s website. Information is systematically updated and corrected. When making your next purchase, request licensing documentation for the product. Purchasing on dubious markets will bring only one benefit - temporary savings. After some time, the engine will begin to present surprises in the form of reduced power, higher fuel consumption, and premature wear. There is only one explanation - the lubricant contains no additives other than the mineral base. Accordingly, rubbing parts are not protected at all. Major repairs will soon make themselves felt. You have to choose: a virtual illusion of savings or a long service life of the vehicle. Everyone decides for themselves. Best wishes.

The key to long-term and trouble-free operation of any car is often high-quality motor oil. This statement is especially true if we talk about domestic climatic conditions, when a significant part of its resource can “fly away” with just one engine.

What to do and what to use?

Unfortunately, motorists do not always buy really high-quality lubricants, since they focus primarily on their cost. The realization that this path is flawed and does not lead to anything good comes only after the first serious breakdown and in fairness, we note that many high-quality oils do not always have a reasonable price, and therefore motorists have to look for a cheaper, worthy alternative.

Does such a thing exist in nature? Fortunately, yes. For example, Lukoil oil (synthetic) 5w40. Reviews indicate that with characteristics not inferior to many imported analogues, it is much cheaper. In addition, this lubricant is much better adapted to very unfavorable climatic conditions, which cannot in all cases be expected from foreign analogues.

Thus, many French oils turn into jelly even at temperatures below -30 degrees Celsius. How does Lukoil (synthetic) 5w40 oil behave? Reviews say everything is ok. In order not to be unfounded, we present the main operational characteristics of the product.

Stated characteristics

The manufacturer himself provides the following data by which one can judge the suitability of using the oil in the specific conditions of our country:

Viscosity class - 5W-40.

At a temperature of 100°C, the kinetic viscosity is at least 12.5/14.5 mm2/s.

The minimum viscosity index is 150 units.

The minimum flash point (with access to oxygen) is -210 °C.

Hardens at temperatures from -37 °C.

The average alkaline number is 7.5 mg KOH/g (not a very good indicator).

The percentage of sulfated ash content is 1.2% by mass volume.

This is how Lukoil (synthetic) 5w40 differs. The characteristics of this oil are such that they allow us, with a clear conscience, to put it on a par with many well-known imported lubricants. Although they are not very different from domestic products in all the above-mentioned features, they most often cost several times more.

Many car enthusiasts (even from the northern regions) confidently say that with Lukoil the car starts better (when compared with domestic and foreign analogues). In addition, during major repairs and maintenance it is discovered that the parts are almost completely free of even traces of soot and deposits.

Important Note

If you have filled this oil for the first time, and we are talking about a car that has been operated for a long time using low-quality oil and fuel, experienced car enthusiasts strongly advise flushing the engine before changing the lubricant.

After driving about seven to eight thousand kilometers, the oil will need to be drained again, and in this case you will need to use some certified engine cleaning composition, from which Lukoil additives probably washed off a huge amount of dirt. People experienced in this matter say that after such a procedure the car begins to drive much better, fuel and oil consumption decreases.

Of course, you shouldn’t expect that such a banal operation will increase the power of the engine or bring its technical condition to the level of the one you just purchased. Miracles, unfortunately, do not happen.

Does the oil have international certificates of conformity?

Yes, this is also characteristic of Lukoil (synthetic) 5w40 oil. Reviews say that it can be poured into the engines of almost all foreign cars without any problems, which is a rare achievement for domestic products. Foreign experts fully agree with this assessment, as they have awarded the lubricant many international certificates of conformity. The most important of them are the following: SAE, API SJ/CF, ACEA-A3-98 and ACEA-B3-98. Even Mercedes Benz has tested and approved this lubricant for use in their vehicles in the recent past. And this says a lot! Thus, Lukoil (synthetic) 5w40 SN oil is quite suitable even for filling into the engines of really expensive and high-status cars.

Supplied in canisters of one, four and five liters, like all normal manufacturers). The average price is 100, 400 and respectively. Just for the price alone, you can literally fall in love with domestic oil, since foreign manufacturers ask for at least twice as much money for their products.

Main distinctive features

What else is characterized by Lukoil (synthetic) 5w40 oil? We will look at reviews about it a little later, but for now we will describe how, in the opinion of Lukoil itself, its products, which are so loved by domestic motorists, are different.

The product in question is universal, suitable for use at any time of the year. It is produced from a high-quality mineral base with a low paraffin and sulfur content, adding almost the same additive packages that foreign companies use to improve performance.

In principle, it is precisely because of this that this lubricant can rightfully be considered an analogue of the average foreign samples. Experienced users believe that in the latter case we overpay solely for the brand, while the real characteristics remain the same.

In addition, Lukoil Lux oil 5w40 (synthetic) fully meets the requirements of all famous automakers and can be used with equal success in the most modern gasoline engines that are equipped with turbocharging, and in diesel engines of cars, trucks, and buses. It is difficult to say whether this lubricant is poured into passenger buses in the field, but owners of small diesel trucks are happy with it.

They report that Lukoil allows you to save about 5% of fuel when you compare the oil with the products of other companies. Considering its extremely low cost, the picture turns out to be more than attractive.

Useful properties of lubricant

Being absolutely similar in this parameter to the best examples of foreign lubricants, Lukoil 5w40 (synthetic) perfectly cleans gasoline and diesel engines of soot and other categories of contaminants, while perfectly protecting their parts from corrosion in all temperature ranges.

Several times less deposits appear on their structural elements, which helps to start the engine almost instantly in winter conditions, and its rapid pumping and warming up helps to begin instant lubrication of all parts immediately after the engine starts.

Important! Unlike other domestic lubricants, Lukoil 5w40 (synthetic) does not have any harmful effect on the catalytic afterburners of modern cars, and also perfectly protects parts of even highly forced turbocharged diesel engines from wear.

Sulfur and other troubles

The last circumstance is especially important due to the fact that all of the above applies to diesel engines running on low-quality diesel fuel with a high sulfur content, as well as to all categories of injection gasoline engines.

Drivers in Russia say that only thanks to this oil they can avoid serious consequences, having to refuel for a long time at dubious gas stations. However, unfortunately, this does not free you from the need to replace extremely expensive injectors.

Tests by independent experts

Now we come to the most interesting part. No matter how good (according to the manufacturer) Lukoil (synthetic) 5w40 oil is, it is always interesting to learn about the test results of independent experts. As a rule, their data characterizes any product much better. So, here are the actual research results, according to which the “field” performance characteristics of lubricants are as follows:

At 100°C the actual viscosity (kinetic) is 12.38 mm2/s.

The maximum flash point, provided there is free access to oxygen, is around - 224 °C.

Lukoil (synthetic) 5w40 oil hardens at temperatures of only -40 °C and even lower.

The average alkaline number is 9.68 mg KOH/g (which is much better than the official data, oddly enough).

At a temperature of 20°C, the density is 0.8621 kg/l.

Ash content - 1.18 wt%.

At an ambient temperature of -30 °C, the dynamic viscosity was in the range of 6600-4900 mPa.

This is how Lukoil (synthetic) 5w40 oil performed in research. The tests, by the way, showed very good results, which many did not even think of getting from Russian lubricants.

What does all of this mean?

Interesting numbers, but what can they tell the average motorist? Let's reveal and decipher the meanings of individual indicators. Note that there are practically no comments, but it is necessary to especially emphasize the low viscosity values ​​​​in conditions of rather low ambient temperatures. Why is this so important? The fact is that this indicator affects the crankability of engine parts in winter during cold starts.

What do car owners themselves say? Everything is fine with this: it turns out that when using this oil, cold starts no longer cause problems, even at temperatures down to -33 degrees Celsius. Almost everyone says that with this lubricant, the engine runs much smoother and more confidently in such conditions, which is good news.

A spoon of tar

Alas, a photometer test showed that the oil contains a very large amount of suspended impurities. This indirectly indicates that the lubricant contains a considerable proportion of oxide products. It's a shame, because the alkaline number in this test is quite decent. However, there is nothing criminal about this: we can simply conclude that the main indicators are within average limits, not much inferior to the bulk of common oils.

How are things going with the environment?

Lukoil (synthetic) 5w40 “Lux” oil is very popular among a considerable part of car owners. Reviews say that at a ridiculous price we get excellent oil, its characteristics are quite comparable to many foreign analogues.

The only remark concerns environmental cleanliness. A lubricant that initially contains a high content of oxide products and other suspended impurities may cause low purity of exhaust products. Therefore, you should not drive such a car to those countries that zealously monitor the cleanliness of the air.

However, in practice everything is not so sad. In the reviews there is no mention at all that the use of this lubricant would interfere with the vehicle’s normal technical inspection, which is associated, among other things, with analyzing the quality of the exhaust. So the buyers of this lubricant are quite satisfied, since this indicator does not affect the actual performance properties in any way.

Main conclusion

So, how did Lukoil (synthetic) 5w40 Lux oil perform? Reviews, as well as the results of laboratory studies, which we have already cited above, indicate its decent quality. And this is gratifying, since domestic lubricants can rarely please with truly impressive characteristics.

This oil can be safely recommended to almost all motorists. Fortunately, the lubricant is suitable for both diesel and gasoline internal combustion engines. One of its disadvantages is perhaps the high rate of photometric contamination, which implies a large mass fraction of suspended particles from oxidation products.

But in all other respects, Lukoil (synthetic) 5w40 motor oil is not much inferior to its imported “colleagues”. Motorists report that with its regular use, the mileage of the engine before its overhaul significantly increases, and there is practically no soot or deposits on the internal parts of the power plant. Agree that for a synthetic lubricant at this price the figure is close to fantastic!

Therefore, Lukoil Lux 5w40 (synthetic) is an excellent oil that is available to almost anyone due to its low cost. At the same time, the buyer will receive not some dubious slurry, but a high-quality product that will certainly appeal not only to him, but also to his car, regardless of the characteristics.

The review will list the specifications of the motor synthetic oils Lukoil Lux 5w40 reviews about it from users, deciphering the main physical and chemical indicators, and those aspects that you should pay special attention to when choosing this oil.

Comparative tests of Lukoil Lux 5W40 oil with foreign competitors and domestic analogues

Lukoil Lux 5w40 was tested by the editors of the automobile magazine "Za Rulem" and out of ten fully synthetic nominees, it took an honorable third place, losing to the Belgian Xenum X1 Ester Hybrid Synthetic motor oil and the Japanese ENEOS Gran-Touring. The positive aspects of Lukoil oil were noted to be good protective and cleaning properties due to the high alkaline number, as well as a decrease in fuel consumption and an increase in engine power. The disadvantage was the high sulfur content, which means poor environmental performance. But of the domestic synthetic oils, it proved to be the most competitive, and lost tenths of a point to eminent foreign competitors. And since Lukoil Lux 5W40 is almost two times cheaper than the favorites, it can be considered the winner of the test.

This distribution of positive and negative properties is typical for most domestic oils - their protective properties are often excellent, but the environment is relegated to the background.

Who is Lukoil Lux 5w40 synthetic oil addressed to?

An explanation of all of the above for non-specialists and novice motorists:

According to API SN-SF and ACEA A3/B4 specifications, Lukoil Lux 5w40 all-season synthetic motor oil is suitable for most modern gasoline and diesel engines, including turbocharged ones, without the use of multi-stage catalysts, particulate filters and other afterburning systems.

Regarding approvals from automakers, it is interesting that Lukoil Lux passed the MB-Approval 229.5 specification, which is considered demanding in terms of quality.

Based on the mass fractions of elements confirmed during an independent examination, we can say:

1. The content of phosphorus and zinc in oil is significant - these elements negatively affect environmental friendliness, but they are the ones that are part of anti-wear additives.
2. Magnesium and calcium in oil determine its cleaning properties, and their amount here is quite sufficient.
3. The amount of boron in oil is small - according to experts, it provides both detergent and anti-wear properties and does not increase the ash content. In this case, these functions are performed by other elements.

In addition to the physical and chemical properties and the passed specifications, the advantages of this oil include the possibility of purchasing it from an authorized dealer. At any Lukoil gas station you can purchase this motor oil, with one hundred percent confidence that you bought the original.

To specifically determine whether this motor oil is suitable for your car or not, use the oil selection function on the manufacturer’s official website or the operating instructions for your car. But we can say that Lukoil Lux 5W40 fits well with modern domestic cars and fresh budget foreign cars. Filling this oil and changing it twice as often will be healthier for the engine than driving 15,000 km on branded oil without changing it. The fact is that the processes occurring with motor oil in the engine are similar to the wear and tear of any system - at first the loss of properties occurs slowly, but upon reaching a critical level, the motor oil completely loses its original characteristics and causes significant harm to the engine during operation. Therefore, using budget oil such as Lukoil Lux with a reduced service interval looks preferable than using an expensive brand, but with a long replacement period.
