Today we are going to deviate a little from the usual structure of such ratings - “best mineral / semi-synthetic / synthetic oil”. The reason is simple: a particular engine first of all needs the oil viscosity specified by the manufacturer, and modern engines use low-viscosity lubricants (this is usually a high-temperature viscosity of 30, on many engines it is 20). Discussing anything other than synthetics in this context is silly. The division into categories “oil for gasoline / diesel engines” looks no less strange, given that 90% of modern oils have approvals for use in engines of both types, it makes sense to discuss purely “diesel” oil in relation to passenger cars only in the oil segment designed for engines with particulate filters.
Therefore, today we will divide motor oils into categories for their specific application, and not according to virtual and non-practical parameters:
- Oils with high temperature viscosity 40(5W40 in our ranking) is the best option for engines produced in the 90s - early 2000s. For regions of the Far North, it makes sense to consider 0W40 oils, this can significantly facilitate starting the engine in winter.
- 5 W30 today it can be considered universal: this viscosity is used both in budget foreign cars and in premium car engines.
- 0 W20- low-viscosity motor oils used in a large number of modern engines. Moreover, it is categorically not recommended to fill in more viscous oils in them: piston rings, which have specially reduced elasticity to reduce mechanical losses, cannot cope with a stronger oil film, oil burn begins to grow.
- High temperature viscosity 50 relevant for owners who operate their cars harshly - it is not without reason that 5W50, 10W60 oils are commonly called "sports".
- 10W40- the standard choice of owners of old cars, as a rule, is budget semi-synthetics of outdated quality classes - SH, SJ.
- Diesel engines with particulate filters should have a minimum oil loss, which should not give a noticeable solid residue (low ash content). This parameter is critical, therefore, only oils that have the appropriate certification can be poured into the engines of such cars. The vast majority of passenger diesel engines of this type use oils with a viscosity of 5W30, and we will consider them.
Whatever the car, its owner always strives to fill the engine with the best engine oil. This does not always work out, but still this trend is present. At the same time, it is very important for the consumer not to lose vigilance so as not to acquire a fake - there are more than enough of them on the domestic market.
This review will consider the best (purely in our opinion, based on product characteristics and user reviews) lubricants that have proven themselves exclusively on the positive side. For the convenience of the reader, the rating has been divided into the most popular categories of engine lubricants.
Best Synthetic Motor Oil
Synthetic engine oil is much more stable over long periods of operation than mineral and semi-synthetic ones. It withstands high and low temperatures well, does not form deposits and does not freeze in conditions of severe frost, and also has a good washing property. However, the price is also much higher.

3 ELF Evolution 900 NF 5W-40 4 l
Retains its characteristics under peak loads
Country: France
Average price: 1440 rubles.
Rating (2019): 4.7
Synthetic engine oil ELF Evolution 900 NF 5W-40, designed for gasoline and diesel engines, has good anti-wear characteristics. One of its shifts is more than enough for 10 thousand kilometers, while only about 350-500 grams of the total amount of oil goes into soot and idle losses (due to wear of seals). Due to its good lubricating action and high level of reliability, ELF is recommended for motor racing applications.
But for any big advantage, there is a small disadvantage. This brand of engine oil suffers from frequent fakes and the sale of products that do not meet quality standards. However, owners rightly consider this motor oil to be one of the best synthetic products on the market. In the reviews, many of them recommend pouring ELF Evolution into engines that are constantly operating in high load mode, referring to their successful experience.

This is a real find for the "rare" cars of the dashing 90s. Mineral engine oil Lukoil Standard SF / CC 10W-40 is used as a generous source of refueling for engines with increased oil consumption, since it is characterized by a very low cost. The expediency of pouring this oil into old foreign cars is very doubtful - a foreign engine requires more delicate care. But for the products of the domestic auto industry, it will fit perfectly. The only serious drawback is its heat resistance - at low temperatures, the quality parameters of the oil change dramatically, and not for the better.
Advantages:
- oxidative stability at temperature jumps;
- very low price;
- universality;
- retention of viscosity throughout the entire cycle of use.
Flaws:
- a sharp change in quality parameters at low temperatures.
The best engine oils for diesel engines
Engine oils for diesel engines, in fact, are no different from those for gasoline models. Some oil manufacturers allow the use of their products for both types of motor. The main difference lies in the operating conditions: in diesel engines, oil is subjected to greater production and consumption, and therefore needs to be replaced more frequently and periodically topped up.

Country: USA
Average price: 1367 rubles.
Rating (2019): 4.7
General Motors Dexos2 Longlife 5W30 synthetic engine oil is in high demand among ordinary motorists. And the point here is far from being a famous brand. Despite the rather mediocre parameters of quality and operating time (contrary to the longlife prefix in the name), it has good washing abilities, perfectly lubricates the rubbing surfaces of the part, does not form carbon deposits and does not freeze at low temperatures. What else, one wonders, is needed to get the title of “best”? The answer is simple: an increase in the period of work from shift to shift and a more humane price.
However, owners continue to pour this oil into the engine on an ongoing basis. It perfectly copes with its tasks, does not lose viscosity in cold weather and perfectly dissolves sludge deposits, removing them at the next replacement. In addition, Dexos2 Longlife engine oil does not enjoy the attention of scammers and there are practically no fakes on the market.

3 SHELL Helix HX7 5W-40 4 l
Buyer's Best Choice
A country: Netherlands/UK
Average price: 1353 rubles.
Rating (2019): 4.7
With SHELL Helix HX7 semi-synthetic engine oil, there is a very twofold situation. On the one hand, it costs less than its competitors, since it is “semi-synthetic”. On the other hand, it has an obvious loss in performance, largely related to the operating temperature range. But a curious fact and its direct advantage is a long service life. The average duration of use of one serving of semi-synthetic oil is 3-5 thousand kilometers. This composition is able to perform its function for 5-7 thousand kilometers, but its blackening is noted at the average standard mark.
At the same time, the owners could not detect carbon deposits and any noticeable consumption of engine oil, which is an excellent result for high-performance engines. The reviews highly appreciate the washing characteristics and reasonable price. Among the shortcomings, extremely low frost resistance is noted, therefore, semi-synthetic oil is not recommended for use at low temperatures - it significantly loses its fluidity.
2 MOBIL Super 3000 X1 5W-40 4 l
High Performance
Country: USA
Average price: 1890 rubles.
Rating (2019): 4.8
Oil used for four-stroke gasoline and diesel engines with a wide operating temperature range. In hot summers and cold winters, it shows itself in the best possible way - it does not form unwanted soot and does not freeze even in severe frosts (it easily withstands -35 degrees Celsius). But the oil copes with the washing function, alas, not very well. In general, one shift is enough for 7-8 thousand kilometers, even with an aggressive and merciless driving style. But for greater certainty, it is worth resorting to changing the oil every 5-6 thousand kilometers, since its cost allows it to be done.
Advantages:
- good value;
- high quality;
- large operating temperature range.
Flaws:
- many poor quality fakes.
1 Toyota SN 5W-30
Traditionally high quality
Country: Japan
Average price: 2780 rubles.
Rating (2019): 4.9
It is a big misconception that Toyota engine oil can only be used in appropriate cars. Yes, the manufacturer clearly states such a recommendation for use, but in fact it can be poured into any new engine that requires 5W-30 grade oil. There are no complaints from users - “synthetics” last a long time, do not form carbon deposits and have very good washing abilities. One bay is enough for 10 thousand kilometers. Yes, the price of the product is high, but it is fully justified by the high quality inherent in Toyota.
Advantages:
- high quality of the product;
- effective washing function;
- one "portion" can withstand up to 10 thousand kilometers;
- users note the quiet operation of the engine after starting to use the oil.
Flaws:
- not detected.
The weather can be unpredictable. Car drivers are increasingly faced with the need to fill the engine with universal type oil. It is intended for use in hot or cold weather. In order for the unit to work efficiently both in frost and heat, oil is used 0W40.
This consumable is produced by many large companies. The presented standard has a number of special characteristics. What features the presented oil has, it is necessary to consider in more detail.
general characteristics
0W40 is designed to protect the motor from abrasion and premature failure. It removes excess heat from rubbing mechanisms. Also, this product covers all metal surfaces with a thin film. It provides good sliding of rubbing elements, prolonging their operation.
Also presented materials protect the motor from corrosion. They remove carbon deposits, dirt and soot from the engine system. These particles are suspended in the oil. Over time, they accumulate. The grease changes its color to a dark, dirty shade. In this case, it is necessary to make a replacement. Otherwise, the grease will no longer be able to hold contaminants in itself. They will settle on metal surfaces, causing microscopic damage to parts.
It is on the correct choice of engine oil that the easy start of the engine in cold weather, as well as the absence of overheating in the summer, depends. Previously, manufacturers supplied the market with oils intended exclusively for the warm or cold season. Today, vehicle owners are acquiring versatile products. They are designed for use in both hot and cold weather.
For each specific operating condition, certain lubricants are suitable. The full operation of the motor, as well as its durability, depends on the correctness of their choice.
For the engine of your car, you must use only the oil recommended by the manufacturer. If you want to change the lubricant to another variety, you should choose a composition with a similar set of additives. Products from different manufacturers may conflict with each other. This causes deviations in the operation of the motor.
Viscosity index
One of the most important indicators oils 0W40, specifications which is taken into account when choosing, is its viscosity class. Most often, this parameter is specified in accordance with the SAE (Society of Automotive Engineers) standard. It was this association that was the first to propose a classification of oils in terms of viscosity class. It releases only 6 winter and 5 summer lubricants.
In accordance with this technique, three types of viscosity are distinguished. There is winter, summer and all-weather oil. The first category has the letter "W" in its markings. The number next to it indicates the permissible limit at which the product is operated.
Summer lubricants do not have letters in the marking. They only have a number. It indicates the upper limit of viscosity. For universal formulations, the lower viscosity limit is indicated first, and then the upper one. quite fluid, which allows you to start the engine at very low temperatures. Its upper viscosity limit indicates the possibility of engine operation at high thermometer readings.
In other words, the oil of the presented viscosity grade is suitable for severe winters and hot summers. For a hot southern climate, it is necessary to purchase products with a high level of viscosity. This will keep a thin film of lubricant on the parts even in extreme heat.
Advantages
Engine oil 0W40, 5W40 is intended for use in the climatic conditions of our country. It withstands severe frosts. It's a pretty thin lubricant. Thick varieties are designed for use at high temperatures. Under these conditions, the lubricant becomes more fluid and can completely fly off the mechanisms and parts. In this case, dry areas are formed, which will collapse during friction.
Oil of viscosity grade 0W40 can ensure normal engine operation in winter at temperatures up to -40 ºС, and in summer - up to +35 ºС. This indicator also depends on the manufacturer. Each company uses a certain set of components for the manufacture of oil. Therefore, the main characteristics may vary slightly between manufacturers of different formulations.
However, the main benefits remain in each type of oil. This class of lubricants is manufactured in accordance with the highest requirements of global vehicle manufacturers. This product has good performance. It saves fuel consumption. High performance depends on the composition of the oil, as well as its additives.
Compound
It is made according to a certain technology. All such products are conditionally divided into several categories according to the composition of the base. A special set of additives is added to it. The base can be mineral, synthetic or semi-synthetic.
In the first variant, oil is processed by distillation and refining. Such a base is used to make cheap varieties of oils that need to be changed quite often. It is used for old-style engine systems. For viscosity grade 0W40, the mineral base is not used in its pure form. It is combined with synthetics. This increases the cost of the product, but also improves its performance.
Synthetics are created on the basis of artificial components. Such products allow for high fluidity of the oil. Synthetics 0W40 ensures stable operation of the motor even at very low temperatures. The product has a low evaporation rate. This is what ensures the ability of the lubricant to perform the functions assigned to it, even in the heat.
Synthetics are also resistant to oxidation and waxing. These characteristics can significantly extend the period of application of the oil. This type of lubricant is the best suited for the loaded operating conditions of the engine on the roads of large cities.
Semi-synthetics combines the qualities of both types of lubricants. This base is chosen for the manufacture of lubricants for medium engine loads.
Shell oil
Experts conducted experiments on a variety of indicators that characterize popular motor oils. Brands such as Mobil, Castrol, Shell, etc. took part in the testing.
When conducting research in the winter, it was found that Shell 0W40 oil has approvals from almost all modern vehicle manufacturers. It provides excellent protection against various types of debris. There is no other oil in this category that cleans the engine so well. This is achieved thanks to a unique set of additives.
Thanks to its balanced viscosity characteristics, Shell 0W40 oil saves up to 1.9% more gasoline than other types of lubricants. It protects moving parts from corrosion and wear. The highly scientific production formula allows the engine to be started even at the lowest temperatures.
The presented oil is designed for gasoline, diesel and gas engines. It is also used for engines that run on biodiesel or gasoline-ethanol mixtures.
Negative reviews include opinions about the high cost of such products (4 liters costs about 2200 rubles), and car owners also blame for frequent fakes.
Lukoil oil
Motor Lukoil 0W40 oil also receives a lot of positive feedback from motorists. This quality composition is made on a synthetic basis. Therefore, its cost is quite high (4 liters will cost about 1900 rubles).
This product has excellent performance. According to expert reviews, the oil has good detergent qualities. It does not need to be changed frequently. For high loads of big city conditions, it is ideal. The engine starts in winter even at -40 ºС. The motor is stable and efficient. Its power is increasing.
The oil contains special additives that protect the car system from corrosion and destruction. Thanks to low burn-in rates, all parts are reliably protected. Dirt and soot can remain suspended for a long time.
Due to its special characteristics, this product is recommended for use by many car manufacturers. It is more suitable for new foreign foreign cars. For old domestic cars, this product is not recommended.
Mobil 1 oil
Motor Mobil 1 oil (0W40) characterized by a fairly reasonable cost. A standard 4 liter canister will cost about 1,700 rubles. It is allowed to be used for both foreign and domestic new cars.
During testing, it was found that the oil solidifies at a temperature of -49 ºС. Such viscosity characteristics make it possible to start the engine in the technical characteristics laid down by the manufacturer in this product, allow it to be used even in conditions of northern latitudes.
It is a general purpose lubricant. It allows you to provide sufficiently good cooling of the system in a hot period.
Means shows good washing qualities. However, when the engine was opened after testing, a certain amount of soot was found on the pistons. At this price, users expect better cleaning performance.
Motul oil
The above motor Mobil 0W40 oil in many respects it is similar to a product of the same viscosity class called Motul. This lubricant is universal. It is suitable for use both at low temperatures (-48 ºС) and in hot weather.
The product is available in 5 liter cans. Their cost is about 2500 rubles. Acceptable cost makes the product popular among drivers. It can be poured into the engine of both foreign and domestic cars.
Its energy-saving and washing qualities are also noted. In almost all areas of testing, this lubricant showed good results. At high engine temperatures, the amount of deposits on the pistons is negligible. This makes the product in demand, especially in the loaded conditions of movement on the roads of the metropolis.
Some drivers claim that the cost of the presented funds is high. However, the amount of oil in the canister will be more than other manufacturers. In terms of the price for 4 liters of oil will be acceptable.
Oil "Castrol"
European-made Castrol is also known to domestic consumers. This product is available in 4 liter cans. The cost of consumables is about 1750 rubles.
At an affordable price, this tool has high performance. This oil solidifies at a temperature of -52 ºС. This indicator is a record among the lubricants participating in the test. This speaks of the high quality of the base.
An effective set of additives allows Castrol oil to provide high-quality cleaning action. After testing the product under high engine load, high piston cleanliness could be observed. Also presented means protects the metal elements of the system from oxidation.
Many drivers choose this type of lubricant due to its affordable cost and high European quality. However, in terms of energy saving, the presented product is somewhat inferior to other test participants. This indicates a higher fuel consumption during engine operation.
Oil Liqui Moly
The most expensive among the considered products of well-known manufacturers turned out to be oil. It is sold in five-liter canisters. The cost of such a product is 2700 rubles. The manufacturer of the presented lubricants is Germany.
Liqui Moly has the approvals of many major engineering concerns. Its performance remains top notch. Oil allows you to quickly start the engine at low temperatures. This provides really reliable lubrication of rubbing mechanisms.
Also, the presented tool allows you to significantly save fuel costs. The disadvantage is the insufficient level of detergent qualities. On the cylinders, a sufficiently large amount of soot and soot is determined after the tests. Piston rings fail faster than with other types of products.
Liqui Moly is known for the longest aging period. It can be used for quite a long time. The oil will not burn out.
Having considered the features that characterize 0W40 oil, as well as the reviews of experts and experienced drivers, we can conclude that it is necessary to use such a composition in the engine of your car.
Oils that guarantee the possibility of starting down to minus 35 ° C are entirely synthetic and the most expensive. Today, almost all foreign manufacturers have such. Among domestic ones, we found 0W40 oil in only two - Utech from Yukos and AGA from AJA AvtoMag LLC.
Divide the class into groups
Motor oils are divided not only into classes (by viscosity), but also into groups (by quality level). There are several rating systems. The most famous American classification according to API: oils for gasoline engines are assigned the index SG, SH, SJ, SL, SM - the further the second letter is from the beginning of the alphabet, the higher the oil's ability to withstand loads. The European classification ACEA (designations A2, A3, A4) is gaining more and more popularity. The higher the number, the higher the quality level. For diesel engines, other combinations of letters and numbers are used. It is permissible to fill in the oil that meets or exceeds the quality level required by the vehicle manufacturer. This time we decided to compare only the oils within each group, so there were leaders in each of them.
Physico-chemical properties were checked for the requirements of GOST R 51634-200 and SAE j-300 Dec 99, and the quality compliance with the API group was checked using the “Sliding Ring” device (ЗР, 2006, No. 11). According to the “ring” test, points were given: the more there are, the more readily lacquer deposits form on pistons and cylinders. A lot of deposits are bad for a motor, especially a highly forced one.
Viscosity was measured both at 100°C (the oil flow through the calibrated hole per minute was monitored) and at minus 35°C (the shear force in the rubbing pair was determined, that is, dynamic viscosity). If the dynamic viscosity is greater than 6200 MPa.s, the starter is unlikely to turn the crankshaft.
We checked the pour point, at which the oil thickens so much that it no longer drips. For class 0W40, it will, of course, be below minus 35°C. However, at such a low temperature, the motor may not start for another reason, even if it is untwisted.
We looked at the ash content. According to the standard, it should not exceed 1.3% (the less, the better). If the rate is exceeded - wait for the formation of soot.
GOST overboard
Of the 14 purchased samples, two were beyond the requirements of the standards. Tecsint SX oil does not correspond to the declared 0W40 class - in severe frost, the starter most likely will not crank the crankshaft, Excellium went beyond the standard for ash content - 1.48 instead of the permissible 1.3%.
How to choose oil
Having carefully studied the results obtained, we were convinced that no one succeeded in making the best oil in all respects. Therefore, the choice must be approached creatively.
If your car's engine is already worn out, pay attention to the minimum ash content: why pollute? And if the motor is new, it is better to choose an oil with a minimum score in the “varnish formation” column.
Doubt? Then rely on our arrangement, in which we took into account all three parameters (viscosity, ash content, varnish formation) and, having evaluated each in points (from 1 to 5), received a comprehensive assessment. In it, we considered each parameter to be an equal “player”. If any of them seems more important, make an informed choice based on the tables presented.

How is Zhvanetsky about the difficulties of choice? “Five are very large, but yesterday. And today there are three, but small. Same with engine oil. Expensive imported synthetics, which promises to last 15,000 km, or affordable Russian oil, which is changed twice as often - that's the choice!
Let's set aside the purely monetary question for now. Now we are only interested in the health of the motor, and therefore we will compare the levels of pollution, control wear and tear and evaluate fuel economy.
Let's limit the choice
We are not going to compare the top supersynthetics with the cheapest mineral water, the prices for which sometimes differ by twenty times. We are interested in those oils that can be recommended for the same engine. SAE viscosity grades must match - and we will take the most common grade 5W‑40. The quality categories must also match. Modern expensive synthetics do not fall below the SN / CF level according to the API classification (A3 / B4 according to ACEA) - that's where we will stop. The car manufacturer usually does not specify the type of oil, but comparing synthetics with mineral water is somehow awkward.
As a result, we chose two synthetic oils - a European one at the price of 1950 rubles for a four-liter canister and a Russian one: 940 rubles for the same capacity. They took one canister from the European one, and two from the Russian one, since it will have to be changed after 7500 km.
About the methodology
The VAZ‑21126 engine operated on expensive and cheap oils in completely equivalent conditions - in the same modes, on the same gasoline, at the same outside temperature. The number of engine hours in both cases is equivalent to 15,000 km. Moreover, Russian oil was replaced with fresh oil in the middle of the “distance”.
We studied the dynamics of changes in engine parameters (power, efficiency and toxicity of exhaust gases), periodically took samples to investigate the rate of oil aging and the accumulation of wear products. At the end of the tests, the motor was opened and evaluated according to the color scale of the deposits after working on one or another oil. Piston rings and crankshaft bearing shells were weighed before and after testing to assess the wear rate of the main friction units.
What did you see
Expensive oil for a full test cycle did not lose its performance, although the parameters sank noticeably - both for the oil and for the engine. Fuel consumption by the end of the tests has grown by 3-4% compared to the initial stage; power dropped by 2.5%. For 15,000 km of nominal mileage, a little less than a liter of oil was consumed from the initially filled four. That is, the regime "from shift to shift without topping up" was maintained.
When running on budget oil, the engine initially showed a slightly higher fuel consumption (+ 1.5%) than on the European one. Obviously, this is a consequence of a higher viscosity, which, however, does not go beyond the SAE tolerance for oils of this class. This gave a small (practically within the margin of error), but a steady increase in power (slightly less than 1%). The budget oil quite expectedly had a higher aging dynamics. For half the test cycle (7500 km), fuel consumption increased by 2.1% (when working on the road - by 1.5%). The second half of the tests, after changing the oil, the engine worked almost the same - the difference between the final measurements at 7,500 and 15,000 km lies within the measurement error. As a result, the engine worked more economically on two fills of budget oil than on one fill of expensive oil: the difference in favor of the domestic product was 1.1–3.0%, depending on the operating mode (average -1.5%).
Analysis of the main physico-chemical parameters of oils, characterizing the rate of their aging, confirmed the results of motor tests. For expensive oil, at the end of the “run” (15,000 km), the viscosity increased by 11%, the base number decreased by 30%, but the indicators did not go beyond the rejection limits. In inexpensive oil, after 7500 km, the increase in viscosity was 3.5% (first fill) and 5.8% (second fill), and in the sample from the second half of the “run”, the aging rate turned out to be higher: contamination of fresh oil with residues of used oil, which did not merged during replacement. The base number dropped by 13–15% relative to the initial value - by the way, higher (this is good for difficult Russian conditions) than that of expensive European-made oil.
And now let's evaluate the result in money. One canister of expensive European oil, one filter plus the cost of an oil change is about 2350 rubles. Two budget containers, two filters, two replacements - this is 2680 rubles. If the work is not taken into account (that is, change the oil yourself), the costs will be equal - 2050 and 2080 rubles, respectively. And if you take into account the difference in fuel consumption? On domestic oil, the engine was 1.5% more economical, and for each test cycle it ate about a thousand liters of "ninety-fifth". If we take the price equal to 38 rubles per liter, we get 570 rubles of savings. Not much, but the balance has swung towards more frequent oil changes.
However, winning on fuel is not the most important thing. The health of the motor is more important. There are three evaluation criteria: reliability of operation (no failures due to the use of suitable oil), surface cleanliness, wear.
Reliability of work - full. No failures during the tests were recorded, emergency topping up of oil was not required. However, we did not expect anything else from oils of the SN quality group. The level of high-temperature deposits in both cases was almost the same. It is obvious that the Russian oil could not lose to European oil with a higher quality thanks to half the replacement interval. Yes, and the initial (as well as the final) alkaline number of our oil is higher, and this is one of the indirect indicators of washing ability. As for low-temperature deposits on the surfaces of the valve mechanism and oil pan, the European product performed slightly better. Everything is obvious here: it uses a higher quality base oil. However, the difference is close to the error of the test method.
But when assessing the degree of wear, we found a clear effect of an intermediate oil change. This is especially noticeable in the piston rings (and hence in the cylinders). Dirt accumulated in the oil, especially metal particles torn from the surface of parts, works as an abrasive, and no anti-wear additives of the highest quality oil can cope with this trouble. Only the timely removal of the abrasive from the motor will help - when changing the oil. It is impossible to make an exact conversion into rubles in terms of engine wear. But the scales are increasingly leaning in favor of reducing the service interval.
Three or five?
So, our experiment fully proved the feasibility of using two domestic cans (THK Magnum Ultratec, Sintoil Platinum, LUKOIL Lux) instead of one European can (Shell Helix Ultra, Castrol Edge, Mobil Super 3000) - confirmed by both the wallet and the health of the motor.
Of course, you can shorten the oil change interval by always using only an expensive imported product - there will be more benefits for the motor. But we must not forget about reasonable savings either.
In addition, we conducted the tests under ideal laboratory conditions - warm, clean, on proven gasoline. And as practice shows (and our previous research in ZR, 2015, No. 11), even expensive synthetics do not always withstand the notorious 15,000 km of run. Most oilers consider Russian working conditions to be almost extreme. At the same time, everything that happens with engine oil resembles the process of wear of any technical system: until some operating time, aging is almost imperceptible, and then its rate increases sharply. In engineering, this condition is called catastrophic wear - and the same rule applies to oil. It is important to change the oil before this critical moment.
So, even "cool" oil, giving up, causes damage to the motor. And to protect yourself from trouble, you need to replace it more often. If it is not possible to often buy an expensive product, then obviously high-quality affordable oil, subject to its more frequent replacement, is more useful for the motor.
