How to choose engine oil

In modern realities, not only the safety of your own funds, but also the working life of the car depends on the correct choice of engine oil. That is why the personal preferences of car owners become the subject of heated disputes, which, however, do not exclude the possibility of choosing the wrong technical fluid. In addition, the problem of counterfeit products has become aggravated, of which there is a lot in the domestic market of Russia now. Due to the aforementioned difficulties, the magazine decided to independently understand the situation, as well as give a number of very valuable and universal advice on how to choose a good engine oil.

1. Decide on the type of oil. All automotive oils are classified into synthetic, semi-synthetic and mineral oils. The first and second are typical compositions for brand new engines, which are expensive and capable of reliably protecting the power plant from overheating and increased wear. The third type is the lot of older cars that are living out their days, which (with proper use) can also have a positive effect. Always pay attention to the manufacturer's recommendations, but also do not forget about the condition of your vehicle.
2. Don't forget about viscosity. The marking of this parameter looks like this: 5W30, 0W40, – and implies several important operational values ​​at once. The first figure is the viscosity coefficient itself, which shows how liquid a particular composition is under normal conditions. The second digit (after the letter 'W') means the maximum minus temperature threshold at which the oil maintains its viscosity in an acceptable state. When this threshold is exceeded, the composition seizes, as a result of which indirect heating of the engine will be required for the possibility of its subsequent start. A comparison of the main advantages and disadvantages of the two most common oils is shown in Table 2.
3. A little bit about falsification. The problem of counterfeiting oils has always existed on the domestic market, but recently the “tragedy” has become rampant. In order not to fall for the bait of forgers, remember two simple rules:
4. As a rule, only well-known brands of automobile oils are subject to counterfeiting.
5. Manufacturers were very concerned about this circumstance, and therefore began to equip their canisters with 'tricky' opening systems (with seals of various types), as well as pour oils into cans, which are almost impossible to copy with factory stamps and seals.

Advantages and disadvantages of oils depending on the type

Oil type	Advantages	disadvantages
Synthetic	+ Ability to work in a large temperature range + Rich complex of additives allows maintaining nominal performance throughout the entire service life + Viscosity coefficient that satisfies the conditions of constant lubrication of rubbing surfaces + High resistance to oil film tearing even with excessive engine heating (implemented in a number of oils with 'smart' modifiers) + Pronounced washing functions	– High chemical activity – The most expensive type of oil – Diluting the base with semisynthetics is not possible
Semi-synthetic	+ The cost is slightly lower than that of pure synthetics + Improved performance + Optimum viscosity at various engine operating conditions (due to the composition) + Can be mixed with both synthetic and mineral oils + Optimum reactivity that does not require the addition of a large amount of filler elements	– Temperature conditions are lower than that of synthetic oil – The recommended mileage intervals between changes are 5 thousand kilometers (almost half lower than that of synthetic oil)
Mineral	+ Lowest price on the market + Acceptable level of quality achieved by distillation and fine refining of crude oil to the desired fraction + Increased viscosity index – oil loss due to wear of seals is minimal	– Fast development of the resource (mileage between fillings is on average 3 thousand kilometers) – Poor operating temperature: the absence of synthetic additives contributes to the formation of carbon deposits at high temperatures and freezing of oil at low – May include minor amounts of parasitic impurities filtered by distillation

Best synthetic motor oil 5W40

Motul 8100 X-cess 5W40

Rating: 4.9

The deserved leader of the category is the motor oil from the French company Motul, which has the largest and most diverse 'package' of additives. 8100 X-cess 5W40 provides control of all the most critical operating parameters, up to pressure and viscosity retention at various temperature conditions. A number of elements introduced into the base of the oil provide temporary restoration of imperfections in the microstructure of mating parts, provoked by the complete enveloping of the latter with a durable oil film.

An important advantage of the Motul 8100 X-cess 5W40 is a decent operating life of one fill, exceeding 10 thousand kilometers (however, it is better to change the oil after reaching this mark). It was also found that the composition provides more economical operation of the engine, allowing you to save up to 1.7% of fuel (coupled with a good set of candles, this figure can increase significantly). The French once again managed to surprise car owners with an extremely productive product, the complex of actions of which significantly exceeds that of all the competitors cited.

Advantages

• the effect of restoration, protection and cleaning of the engine;
• high energy efficiency: saving up to 1.7% of fuel;

disadvantages

• not found.

XENUM WRX 7.5W40

Rating: 4.8

The next line of the rating goes to XENUM WRX 7.5W40 oil, designed for use in engines with modern catalysts and turbines. The main 'protégé' of this composition is the most iconic model of the Japanese brand Subaru – Impreza WRX, which, in fact, was used to test the performance along with the hidden capabilities of the filler elements. Which should be said separately, since microceramic particles with esters are very rare. The base supplemented with such elements not only has a lubricating and cleaning effect, but also helps to restore the microstructure of worn surfaces.

The intermediate viscosity coefficient XENUM WRX 7.5W40 provides an optimal balance of the characteristics of the oil film, preventing it from tearing during overheating, and also prevents the oil from freezing under hard minus conditions. Such oil is supplied to the market exclusively in plastic containers, however, as the manufacturers themselves note, it does not experience any problems with counterfeiting.

Advantages

• optimal combination of price and quality;
• inclusion in the mechanism of operation of the reduction processes tied to the settling of ceramic particles;
• large shift interval (about 10 thousand kilometers);
• low spending rates;
• modified viscosity to take advantage of the 5W and 10W oils.

disadvantages

• not found.

IDEMITSU Zepro Racing 5W-40

Rating: 4.7

IDEMITSU Zepro Racing 5W-40 engine oil, which came straight from Japan, is a more advantageous analogue of the German Synthoil High Tech composition, developed taking into account the operation of engines at their maximum performance indicators. Oil film rupture here is a rather rare phenomenon, even at extremely high temperatures, which is excellent for engines with turbochargers (i.e., for sports cars).

The composition based on polyalphaolefins is extremely resistant to various kinds of fluctuations in operating parameters, which positively affects the maintenance of viscosity and lubricity. This oil is packaged exclusively in metal boxes with a volume of 1 and 4 liters, which excludes the possibility of purchasing counterfeit products. It costs, of course, not too cheap, but it confidently fulfills the required working resource to the limit.

Advantages

• can be used in heavy duty turbocharged engines;
• maintaining operating parameters within a fairly strict operating framework;
• distribution in cans, excluding the possibility of stumbling upon a fake;
• approval of a number of Asian, American and European automotive giants.

disadvantages

• not found.

LIQUI MOLY Synthoil High Tech 5W-40

Rating: 4.7

Synthetic oil of German production, made on the basis of polyalphaolefins. Designed for use in vehicles adhering to API and ACEA classifications, including those with forced multi-valve engines.

According to the classics of the genre, the manufacturer offers users a whole set of positive effects from the use of LIQUI MOLY Synthoil High Tech 5W-40, from reducing friction to maintaining the optimal structure over the entire temperature range. All this is achieved due to a complex of freshly developed 'smart' additives, which are activated under strictly defined engine operating parameters. The rational mechanism of action allows the oil to maintain its performance characteristics throughout the entire warranty period – namely, 10 thousand kilometers per filling. However, consumers prefer to replace them a little more often, noting a noticeable decrease in wear of rubbing parts (and carbon deposits) in terms of indirect indicators of the pollution of the spent portion.

Advantages

• optimal viscosity at low temperatures;
• long service life (up to 10 thousand kilometers);
• low consumption;
• a noticeable decrease in frictional processes and the formation of carbon deposits;
• a complex of 'smart' additives that are activated under strictly defined conditions.

disadvantages

• not found.

'Lukoil Lux' 5W / 40

Rating: 4.6

The only product of a domestic manufacturer in the category that received truly high ratings from independent experts and consumers. It is 100% synthetics with a complex of additives that protect the car engine from the very moment of start-up. Has a low susceptibility to soot and a characteristic cleansing action designed to gradually remove old oil deposits left over at changes in temperature.

It is noteworthy that the Russian oil Lukoil Lux 5W / 40 has received approval from prestigious global car manufacturers, which include Volkswagen (including the concern Porsche, a member of VAG -group), Renault, BMW and, of course, 'VAZ'. Due to the optimal temperature regime, the composition retains sufficient viscosity down to -40 degrees Celsius, which allows it to be used both in summer and winter.

Advantages

• a complex of active additives that protects the engine from the moment of starting;
• optimal viscosity when reaching the limiting temperature;
• a large number of approving reviews;
• compliance with the quality standards of ryazh of premium car manufacturers.

disadvantages

• valid service life (replacement should be done every 5-7 thousand kilometers).

Advantages and disadvantages of 5W30 and 5W40 viscosity oils

Composition	Advantages	disadvantages
5w30	+ Provides a positive effect in cold weather – the engine cranking up with a low oil viscosity goes better, as well as the operation of the oil pump + Well suited for motors with low operating temperatures	– At high temperatures, the oil film enveloping the moving parts of the engine is subject to rupture and a complete loss of working properties
5w40	+ A dense composition that thoroughly lubricates the rubbing surfaces of the engine + When heated to high temperatures, it does not undergo a breakthrough of the oil film, contributing only to its thinning to acceptable values + Ideal for engines with high heat dissipation	– In its standard form, it has a high viscosity and, as a result, forms a thick oil film, due to which the gears may not be completely enveloped. In this case, it leads to soldering and increased wear of the rubbing parts.

The best semi-synthetic oil 10W40

Motul 5100 4T 10W40

Rating: 4.9

The French oil Motul 5100 4T 10W40 is intended for filling into four-stroke engines of motor vehicles, and therefore it will not be entirely correct to compare it with full-fledged representatives of the auto segment. The base composition here was supplemented with an ester base, which made it possible to largely stabilize the performance and oil consumption for waste, which, in turn, had a positive effect on the dynamic performance of the motors themselves. First of all, on fuel consumption: independent studies have shown an effect of 1.3%, which is not such a weak increase in the long term.

It is noteworthy that the Motul 5100 4T 10W40 can also be used in engines that support EURO 2 and EURO 3 standards, that is, equipped with catalysts and exhaust recirculators. For the rest, scooters, motorcycles without installed catalysts, as well as all-terrain vehicles, become the “clients” of this technical fluid, and in all these cases the composition manifests itself without complaints.

Advantages

• excellent semi-synthetics for 4-stroke motors of motor vehicles;
• positive economic effect from the application;
• high stability of parameters due to the introduction of the ester base;
• optimal viscosity level.

disadvantages

• not found.

LIQUI MOLY Super Leichtlauf 10W-40

Rating: 4.8

The production of this oil was based on hydrocracking technology, thanks to which it was possible to preserve the most important elements of the structure of the raw material and transfer them to the finished product. Semi-synthetics LIQUI MOLY Super Leichtlauf 10W-40 can act as an alternative to inexpensive synthetic compounds, not losing in the least in terms of durability or in protecting the engine from negative operating factors. Oxidation processes in it are weak, as well as the consumption of waste at elevated operating temperatures. Thanks to this, the oil is able to work with heavily loaded engines (gasoline and diesel), which have turbochargers and intercoolers in their design.

It is noteworthy that the main consumer of the German design is … German cars. LIQUI MOLY Super Leichtlauf 10W-40 has an admission to motors Mercedes – Benz and concern Volkswagen, including their elite series. This is a prominent representative of his companies, which once again proves that high-quality semi-synthetics can be no worse than synthetic oils.

Advantages

• exclusive admission to engines of famous German car manufacturers ('conveyor' bay);
• the ability to work with forced gasoline and diesel engines;
• high resistance to oxidation and fumes;
• full production after 8 thousand kilometers.

disadvantages

• not found.

Lukoil Lux 10W40

Rating: 4.7

The domestic product, alas, does not reach the confident leadership in the category, but nevertheless managed to get into the list of the best. Semi-synthetic 'Lukoil Lux' 10W40 is an excellent combination of price and proper quality, which is enough for 8 thousand kilometers in abundance. In fact, no one demands more from him: it has been established that at the time of production, with the original viscosity, the pH balance of the composition is greatly underestimated (turning, in fact, into alkali), amounting to about half of the nominal indicator of 7.5 units.

Lukoil Lux 10W40 also performs well in terms of metal wear prevention. There are small tears in the oil film at serious temperatures and engine speeds, but this is extremely rare, and only in worn out cars. As a result, a 4-liter canister of such a composition can be bought for the price of a good-quality liter synthetics, while serving (quantitatively) 40-50% longer than an analogue that is more 'rich' in additives.

Advantages

• good antifriction properties;
• full oil production occurs with a mileage of 7-8 thousand kilometers;
• excellent price in accordance with the nominal volume;
• optimal stability of operating parameters at nominal operating conditions of vehicles.

disadvantages

• Difficulty starting the engine in frost.

The best mineral motor oil 15W-40

MOL Dynamic Transit 15W-40

Rating: 4.9

MOL Dynamic Transit 15W-40 is a very good quality oil for use in high mileage automobile engines. It combines the functions of economy and reliable protection, not allowing the engines to 'bend' completely, maintaining them in a stable working condition. It meets the environmental safety standards EURO 4 and EURO 5, and therefore it is often used when servicing a fleet of cars in transit services, courier deliveries or taxis.

Another indisputable advantage of this 'mineral water', which is mistakenly passed off as semi-synthetics, is the cost parameter. The price per liter here does not reach the threshold of 400 rubles, and therefore the purchase of, say, a 5-liter container with technical liquid will cost the same as a liter portion of full-fledged synthetics. In general, the consumers of MOL Dynamic Transit 15W-40 have negative emotions, and the low cost actually plays on increasing the intra-segment popularity.

Advantages

• qualitative impact on the operating parameters of engines;
• very low price;
• viscosity sufficient for operation under various temperature conditions.

disadvantages

• not found.

Quicksilver Heavy Duty Diesel 15W-40

Rating: 4.8

A special mineral composition for diesel 4-stroke engines with a freezing point of -27 degrees Celsius. Quickilver is famous for its rather original developments in the field of engine oils, and Heavy Duty Diesel 15W-40 is just one representative of the whole galaxy released. Compensation for missing filler materials was carried out here due to a deliberate increase in viscosity, which, by the way, practically disappears when the engine reaches high-temperature operation (at 100 degrees Celsius, the kinematic viscosity index decreases to 14 units).

If we talk about the operation of engines in general, then Quicksilver Heavy Duty Diesel 15W-40 still allows to achieve a certain positive effect. Despite the mineral base, it is capable of working up to 5 thousand kilometers without visible traces of wear of engine elements, it is extremely resistant to fumes and harsh working conditions. And it costs, in comparison with competitors, not so expensive, providing cost savings due to the combination of efficiency and indicated cheapness.

Advantages

• very cheap to use;
• good resistance to fumes;
• the most complete lubrication of the rubbing surfaces of the engine, even despite the pristine high viscosity.

disadvantages

• when the engine is running at elevated temperatures, it almost completely loses its viscosity (and lubricating function).

Best 5W30 engine oil

Motul Specific 504 00 507 00 5W30

Rating: 4.9

Another representative of the French company Motul takes the first line of the rating in an extremely competitive struggle, scratching it out in the component of cost and slightly more popularity among car owners. Specific 504 00 507 00 5W30 was developed by order of the company Volkswagen, where it is used in an extensive range of engines. In general, without having any revolutionary distinctive features, this technical fluid provides an increase in productivity due to cleaning the metal surface from carbon deposits, as well as the most complete lubrication of mating parts.

In turbocharged engines operating at slightly more stressful conditions, Motul Specific 504 00 507 00 5W30 demonstrates high stability in terms of maintaining the integrity of the oil film, which is especially appreciated when overheating and the risk of bringing the metal to adhesions and tears. The insignificant 'drops' of this oil's cheapness in comparison with competitors have honored it with a serious influx of buyers, thereby causing the notorious sign of popularity. In a more global sense, SHELL Helix Ultra Professional and even MOBIL 1 ESP Formula look a little more interesting, but in terms of 'synthetic' indicators, Motul is slightly ahead.

Advantages

• special design for engines Volkswagen;
• excellent combination of price and quality;
• stable work in a wide temperature range;
• pronounced washing and protective functions.

disadvantages

• not found.

SHELL Helix Ultra Professional AM-L 5W-30

Rating: 4.8

The official Shell oil tester represented by the Ferrari automaker confirms the full readiness of Helix Ultra Professional AM-L 5W-30 for the harsh operating conditions of the engine. Otherwise, it is impossible to “survive” on Russian roads – this is the best complex of testing individual vehicle components and technical fluids for “strength”. According to experts, the most remarkable feature of this composition is the high stability of the composition with changes in operating temperature, especially in view of the not very high nominal viscosity. Yes, liquefaction is observed at limiting conditions, but it does not entail the most 'destructive' rupture of the oil film.

The SHELL Helix Ultra Professional AM-L 5W-30 people's test showed that the oil completely solidifies at -47 degrees Celsius, which is almost half the stated results. In addition, an increase in the efficiency of fuel consumption is noted, which rests on an improvement in the lubrication of rubbing surfaces. In general, discarding the high cost parameter, we can state the fact of complete domination of this oil in the segment.

Advantages

• optimal combination of price and quality;
• 1.5% increase in fuel efficiency;
• low point of complete freezing of oil;
• balanced action of additives (cleansing + protection + high performance);
• large shift interval.

disadvantages

• not found.

MOBIL 1 ESP Formula 5W-30

Rating: 4.7

By changing the label, MOBIL 1 ESP Formula 5W-30 has left intact the very essence of its existence: ensuring the most stable engine operation, accompanied by outstanding detergency and tread properties. Due to the low ash composition and the low content of harmful impurities (sulfur and phosphorus), this composition shows itself perfectly when used in tandem with diesel particulate filters and gasoline aggregates catalysts. A complex of additives with different degrees of activation gives the oil high resistance to oxidative processes and the destructive effect of temperature fluctuations, thereby reducing the rate of its aging processes.

According to users, the positive effects of the MOBIL 1 ESP Formula 5W-30 also affect the ease of starting the engine in cold weather. Moreover, high lubricity slightly reduces frictional efficiency losses, which translates into a slight increase in fuel economy. This is one of the best oils in the '5W-30' segment present on the modern domestic market.

Advantages

• high quality of the composition, due to the content of a whole complex of filler materials;
• reduction of friction losses resulting in fuel economy;
• high resistance to oxidative processes and fumes;
• high working life (full production occurs with a run of 10-11 thousand kilometers).

disadvantages

• not found.

LIQUI MOLY Synthoil High Tech 5W-30

Rating: 4.7

The Synthoil High Tech 5W-30 composition from the LIQUI MOLY company opens the rating of giants in perhaps the most popular category of oils. The full-fledged synthetics of the German company in the incarnation of 5W-30 positively stands out against the background of the coarser 5W-40, allowing the engine to work in softer operating conditions. This composition is based on the already familiar base of polyalphaolefins, which allows us to delicately operate new engines, and also provides a good protective effect on worn-out units.

The second important advantage of Synthoil High Tech 5W-30 is a wider compliance list than the 5W-40 version. In addition to the standard list of German automakers, market pillars such as Ford (WSS-M2C 917-A) and General Motors (dexos 2) gave access to their cars. As for the rest, there is practically nothing to note: a standard slip of the tongue in the form of 'reducing harmful emissions' and 'reliable permanent lubrication of rubbing engine parts' is available on every other train, and German manufacturers have not yet been able to reach something more original.

Advantages

• high quality oil due to multilevel cleaning and modification;
• the presence of protective, restorative and cleaning action in the additives;
• an abundance of certificates of compliance with general and corporate quality standards.

disadvantages

• not found.

Best motor oil 0W20

DEMITSU Zepro Eco Medalist 0W-20

Rating: 4.9

The honorable first place in the rating goes to a product of Asian production under the representative office of DEMITSU. Zepro Eco Medalist 0W-20 is a true professional in the economical use of engine resources and increase in engine efficiency. For various reasons, the main one of which is excellent lubricity of parts even at low temperatures, the Japanese managed to increase the engine performance by an average of 1.2%. Yes, the figure looks insignificant, but there is much more meaning behind it than behind any other 'synthetic' indicators.

Such a powerful effect from the use of DEMITSU Zepro Eco Medalist 0W-2 is due to the ideal selection of additive components and methods for cleaning the base, behind which are the advanced achievements of Japanese engineering. Other aspects of the oil do not require special comments – both the temperature range and the mileage between replacements (it can easily withstand up to 10 thousand kilometers) are very high. The final plus should be attributed to the proprietary method of filling the composition in cans, which are almost impossible to forge.

Advantages

• filling in cans with a volume of 1, 4, 20 and 200 liters;
• mileage intervals between replacements reach 10-12 thousand kilometers;
• improving the efficiency of engines;
• pronounced cleansing functions.

disadvantages

• not identified.

MOBIL 1 Advanced Fuel Economy 0W-20

Rating: 4.8

MOBIL 1 Advanced Fuel Economy 0W-20 is a low kinematic viscosity oil with fuel economy properties, confidently bypassing the main group of competitors in this indicator. It is known for certain that the lubricity of the composition significantly increases the efficiency of the unit, reducing friction losses, thereby ensuring the safety of 1.8-2.4% of gasoline. In the long term, this result looks outstanding – so far no one has been able to overcome the effective threshold of 2.0%.

The second positive feature of MOBIL 1 Advanced Fuel Economy 0W-20 is the possibility of equivalent replacement of the rarer 5W-20 composition. Due to its good resistance to thickening under the influence of low temperatures, this oil provides a stable cold start of the engine, reducing the influence of destructive processes and thereby extending its service life. In terms of cost, Mobil is, as always, at the level – with such good quality and durability of one fill, the economic effect will be obvious.

Advantages

• ensuring stable engine start in cold weather;
• high level of fuel economy (up to 2.4%);
• a complex of active cleaning additives that remove sludge from the exhaust and prevent the formation of deposits;
• optimal combination of price and quality.

disadvantages

• not found.

Motul 8100 Eco-lite 0W20

Rating: 4.7

With an abundance of equal competitors, the Motul 8100 Eco-lite 0W20, alas, could not support the breakthrough of his company representatives, having slipped to the third line of our rating. This was largely due to the experience of comparing the composition with the X-lite series, which has more pronounced cleansing, and then protector functions. If we talk about the mileage, then the safe maximum that can be squeezed out of this oil will be about 5 thousand kilometers in urban mode, or up to 7 thousand kilometers with the prevailing driving on unloaded roads.

Partial compensation for the average ash content of Motul 8100 Eco-lite 0W20 is due to the content of the ester base, which, although it involves mitigating the aggressive effects of used components, does not completely neutralize it (for diesel engines). In general, consumers note a noticeable improvement in the performance (mainly gasoline models) of engines, expressed in an increase in the smoothness of operation, as well as zero oil consumption at moderate loads and average daily runs of about 50-100 kilometers.

Advantages

• pronounced washing function assigned to the ester base and additive components;
• stabilization of the engine wear parts;
• extremely low susceptibility to spending.

disadvantages

• not the greatest mileage between recommended shifts.

Best 5W50 engine oil

MOBIL 1 5W-50

Rating: 4.9

A pure synthetic oil from an American manufacturer has finally reached its maximum point, showing incredible results in terms of performance even against the background of not the weakest competitors. According to the glorious tradition of MOBIL 1, the complex of this technical fluid includes a decent amount of esters, which have a positive effect on the safety of parts during friction and heating. The rest of the composition consists of a number of 'smart' additives, which are activated only when strictly defined indicators are reached.

According to experts, the washing function has reached a special expression here: it is largely thanks to it that MOBIL 1 5W-50 has such a powerful regenerative effect on old engines, gradually, over and over again, washing out carbon deposits and other parasitic deposits from the crankcase. Under the influence of strong antioxidants, the composition retains its original form for a long period of time. The mileage between replacements, in a number of registered cases, showed about 15 thousand kilometers without traces of obvious “violence” over the metal of the engine part. An excellent result, especially in view of the full-fledged integrated approach.

Advantages

• the abundance of active ingredients in the oil composition;
• excellent combination of price and quality parameters;
• pronounced cleansing functions;
• very long replacement interval;
• the most complete enveloping of rubbing surfaces with a stable oil film.

disadvantages

• not detected.

LIQUI MOLY Synthoil High Tech 5W-50

High-quality all-season from another German grandee, sharpened to ensure the normal performance of city car engines. Which, however, does not exclude the possibility of using LIQUI MOLY Synthoil High Tech 5W-50 in turbocharged engines subject to significant temperature loads. Possessing a number of approvals (including ACEA A3, ACEA B4, API CF, API SM), this composition takes advantage of the engines of the German automotive industry supplied straight from the conveyor line.

As consumers note, LIQUI MOLY Synthoil High Tech 5W-50 greatly contributes to the normalization of the work of old, well-worn engines, giving them a semblance of a second life. The composition freezes at a temperature of -39 degrees Celsius, which makes it possible to use it even in the Siberian region. As for the mileage on one fill, with the best outcome it can be up to 12 thousand kilometers. However, both the manufacturer and experts recommend changing the portion by 10 thousand times, explaining this by the possibility of complete depletion of the additive complexes.

Advantages

• optimal combination of price and quality;
• long replacement interval (up to 12 thousand kilometers);
• providing an easy start of the engine down to -39 degrees Celsius;
• great option for keeping older engines running.

disadvantages

• not found.

The best engine oil for diesel engines with a particulate filter

Motul 8100 Eco-clean 5W30

Rating: 4.9

And, of course, you can't do without a Motul company representative on the leading line. Motul 8100 Eco-clean 5W30 is a high-level energy-saving oil developed to meet the requirements of modern generation engines with pre-installed catalysts and particulate filters. It has a low ash content and good preservative properties, due to which it prevents the filter elements from clogging up and the exhaust afterburning to fail. From the point of view of 'synthetic' indicators, it is worth highlighting one very important quality: providing a different degree of lubrication of parts, the oil shows a decrease in fuel consumption by an average of 1.7%, which is an excellent result.

As users note, the Motul 8100 Eco-clean 5W30 also works great when paired with old motors, showing their hidden regenerative abilities on them. With the periodic use of the composition, not only a noticeable decrease in the content of wear products is noted, but also a partial recovery of micrometers of the material due to active ions of zinc and other metals. In this case, there is a particularly acute shortage of ceramics, but this is by no means a minus, but the wildest dreams are dreams of further modification of a solid composition.

Advantages

• performs well when working with new and old engines;
• has a hidden recovery mechanism;
• significantly reduces friction and the formation of wear products;
• provides fuel economy;
• has excellent cleaning functions.

disadvantages

• not found.

ELF Evolution Full-Tech FE 5W-30

Rating: 4.8

The first and only representative of the ELF brand, loved by consumers for the extreme delicacy in working with engine parts. Indeed, when using the Evolution Full-Tech FE 5W-30, almost 98% of car owners note a noticeable ease of operation of the power unit, and, as a result, a good economic effect from fuel economy (in the future). However, the increase in power is also present, but in reality it is felt to a lesser extent.

It is much clearer to monitor the performance of the composition when pouring into diesel engines with a particulate filter (low ash content makes it easy to service such models) and turbocharged gasoline engines (where high 'stress resistance' is required to resist breaking the oil film). In general, with a fairly smooth operation, such flaws occur very rarely, without leading to serious consequences for wear and tear of metal from the surface. It is enough for an average of 10 thousand kilometers, but for greater safety it is recommended to change the oil a little earlier. Considering the pleasant cost of this synthetics in the domestic market, we state: ELF Evolution Full-Tech FE 5W-30 is an excellent choice in its class.

Advantages

• optimal cost;
• the presence of an increase in performance indicators and fuel economy;
• good operational life;
• high degree of popularity among car owners;
• good factory quality.

disadvantages

• rare ruptures of the oil film are observed (under stressful operating conditions).

TOTAL Quartz INEO MC3 5W30

Rating: 4.7

TOTAL Quartz INEO MC3 5W30, as well as its competitor in the person of ELF, is the only representative of the TOTAL company, which has recently lost its leading position. Fortunately, she is still capable of shooting pointwise. This oil is one of the best when used in diesel engines with particulate filters, since it has not only a pronounced washing function, but also a low ash content. By allowing combustion in small batches, it prevents clogging and filling of the filter, thereby preventing long-term engine malfunction.

The pour point of TOTAL Quartz INEO MC3 5W30 fluctuates around -35 degrees Celsius, allowing the use of oils in the winter season even in the northern regions of the country. The average mileage until the additives and base are completely depleted is about 9-10 thousand kilometers, but in the case of diesel engines, replacement should be done a little more often. In the absence of a large number of fakes (which is the real problem of TOTAL oils) and clearly weak points, this grade of technical fluid is awarded an honorable place in the ranking of the best.

Advantages

• good heat resistance;
• attractive price of high-grade synthetics;>
• low ash content;
• an active complex of detergents that promptly remove carbon deposits from the surface of parts.

disadvantages

• real mileage figures are slightly underestimated.
