14 best diesel oils

* Review of the best according to the editors of ecdfburma.org. About the selection criteria. This material is subjective, is not an advertisement and does not serve as a guide to the purchase. Before buying, you need to consult with a specialist.

Since the diesel engine operates in more severe conditions than standard gasoline analogues, more stringent requirements are imposed on technical fluids for them. So, for engine oil, the key characteristics are resistance to oxidation and the preservation of working properties in the long term, as in diesel engines there is a frequent breakthrough of gases in the crankcase.

Due to the popularity of this market segment, Ecdfburma magazine, together with full-time experts, conducted an independent study, in which a rating of the best diesel oils was compiled, for convenience, divided into four main categories. As the main criterion for the selection of goods, consumer reviews and a final assessment based on them were adopted.

The best synthetic diesel engine oils

LIQUI MOLY Diesel Synthoil 5W-40

Rating: 4.9

High-quality synthetics from the German company Liqui Moly, which has balanced technical characteristics for the sake of the main operational features. The composition of polyalphaolefins and the additive package interacts well with bad diesel fuel, the combustion products of which fall into the crankcase, contribute to the accelerated development of a fresh filling resource. Here, such an effect is not observed: special antioxidant modifiers act as suppressors of negative effects.

The temperature of the total yield point of Diesel Synthoil 5W-40 is -45 ° C, which repeats the SHELL product index and significantly loses to the Japanese Zepro. The viscosity index of this composition fully complies with class (170), in connection with which the product provides stable film formation on rubbing surfaces, protecting the latter from adhesions and dry friction (at 100 ° C, the kinematic viscosity is 14.1 mm2/ sec). This oil can often be seen in brand new diesel cars of the brand BMW, Mercedes and Volkswagen, with which Liqui Moly has an exclusive supply contract.

Advantages

  • excellent compatibility with engines equipped with catalysts and turbocharging;
  • high resistance to oxidation;
  • pronounced washing functions throughout the entire life cycle;
  • low consumption on waste.

Disadvantages

  • oil does not work well in engines equipped with particulate filters.

SHELL Helix Ultra Diesel 5W-40

Rating: 4.8

Diesel oil from the Ferrari title supplier, recreated using Shell PurePlus unique technology. Pure synthetics work well with catalyst and turbocharged engines, meeting API, ACEA, and even BMW's individual approvals. Especially valuable is the use of Helix Ultra Diesel 5W-40 for frequent off-road driving, where the diesel engine experiences the greatest overloads.

In addition, this oil copes with temperature extremes, which is why it is often recommended for use in Russia. Its freezing temperature is -45 ° C, and the flash occurs when it reaches 242 ° C, which is the best result among the competitors. Despite all the advantages of SHELL Helix Ultra Diesel 5W-40 and the possibility of its use in diesel engines not equipped with a particulate filter, experts and users agreed on the main main drawback. Due to excessive popularity, the product became interesting to counterfeiters, which affected the growth of fakes in retail sales. This situation has been haunting the company for a long time, but it has not taken any significant steps to stop this.

Advantages

  • high efficiency of engine support in proper technical condition;
  • has resistance to oxidation;
  • wide range of operating temperatures;
  • performs an important function of neutralizing aggressive substances formed during the combustion of diesel fuel.

Disadvantages

  • a large number of fakes in the market.

IDEMITSU Zepro Diesel 5W-40

Rating: 4.8

The only oil on the domestic market that cannot be faked by unreliable companies. Supplied in a tin container, IDEMITSU Zepro Diesel 5W-40 provides perhaps the most comprehensive protection of the engine from all the negative factors of working on diesel fuel. And even frankly disgusting quality: the oxidation of the composition with the active breakthrough of gases in the crankcase is extremely slow. So much the better for drivers - the interval between replacements can often reach 8 thousand kilometers.

Judging by user reviews, at first glance, the IDEMITSU Zepro Diesel 5W-40 behaves in exactly the same way as most competitors - no major improvement in the softness of the engine is observed. But the little things, as always, lie in the details. The fact is that this oil was developed taking into account the possibility of serious temperature changes due to which the freezing point was “moved” to -50 ° C. Great result, especially for car owners from Siberian cities. As for the shortcomings, neither in the mechanism of operation, nor in the technical characteristics are there - the only serious nuance is hidden behind the high price factor. Otherwise, the oil is perfect, for which it is rightfully included in the rating of the best.

Advantages

  • excellent operational properties - leaves the engine in optimal working conditions;
  • the working life of additives and polyalphaolefin base is enough for 7-8 thousand kilometers;
  • withstands frosts down to -50 ° C;
  • not faked in the secondary market.

Disadvantages

  • very high price.

The best semi-synthetic oils for diesel engines

LIQUI MOLY Optimal Diesel 10W-40

Rating: 4.9

Another representative of Liqui Moly, designed specifically for the specific conditions of the road in Russia. The added additive package provides improved fuel economy (small growth: up to 1.2%), allows you to actively protect the inside of the diesel engine from corrosion, oxides and the formation of other solid impurities, as well as to clean them throughout the entire life cycle.

Perhaps the most striking illustration of the capabilities of Optimal Diesel 10W-40 are outstanding technical specifications. The kinetic viscosity of the composition at 100 ° C reaches 14.4 mm2/ sec, which is an indicator of the continuity of lubrication of rubbing parts even under high temperatures. In turn, the hardening of this semisynthetics occurs at -39 ° C - a fairly high rate even by the standards of pure synthetics. To complete the picture of superiority over competitors, we note that the Optimal Diesel 10W-40 has approvals from recognized automotive giants (BMW and Vlokswagen, and also has API CF and ACEA B3 approvals.

Advantages

  • optimal technical characteristics: viscosity and heat resistance;
  • active influence on the performance of engines: reduction of fuel consumption by an average of 1.2%, as well as increasing the softness of their work;
  • good cleansing ability;
  • The best ratio of price and quality.

Disadvantages

  • not found.

MOBIL Super 2000 X1 Diesel 10W-40 (4 L)

Rating: 4.8

The second line of the rating goes to the only representative of the MOBIL company - Super 2000 X1 Diesel 10W-40, which is one of the premium semi-synthetic technical fluids. But what makes this composition premium? After all, its components do not include additives like molybdenum disulfide, as is the case with the Liqui Moly product, nor any other elements.

In fact, manufacturers themselves came up with the name premium product, in order to increase its popularity and highlight among the gray mass of competitors. Yes, they squeezed the maximum out of a limited package of additives, forcing the oil to work for 5-6 thousand kilometers without complaints. Yes, they have reached technical specifications to excellent performance, even in the case of freezing temperature (-30 ° C). However, conceptually, the oil has no difference from the same Lukoil. Perhaps, in the rank of the advantages of Super 2000 X1 Diesel 10W-40 you can write a moderate price, which is offset by a high share of fakes in the secondary market.

Advantages

  • good temperature stability and protection of parts from overheating;
  • satisfactory washing ability;
  • optimal price level in the secondary market and in the network of services;
  • up to 5-6 thousand run on one fill;
  • provides a comprehensive tread action on old diesel engines.

Disadvantages

  • on the market you can find substandard falsification.

LUKOIL Standard SF / CC 10W-4

Rating: 4.7

The main supplier of oil for conveyor lines of AvtoVAZ PJSC, Lukoil is very popular among amateurs to the extent of a budget and quality product. Despite fame, first of all, as a manufacturer of compositions for gasoline engines, products for diesel equipment can also be found in its lines. Standard SF / CC 10W-4 is one of the prominent representatives of those, which has earned a line in the rating with good operational indicators.

Frozen at -33 ° C, this oil is positioned as multigrade, capable of providing reliable protection and lubrication of engine parts all year round. Judging by consumer reviews, its resource lasts for the same 5-6 thousand kilometers as in the case of the MOBIL product, however, the quality of cleaning decreases sharply after reaching a mileage of 4 thousand. As a second nuance, a totally small number of tolerances and approvals can be noted here: in fact, in the first case only API SF / CC appears, and in the second (approval) - the AvtoVAZ PJSC already mentioned above. Despite all the shortcomings of Lukoil, the SF / CC 10W-4 standard shows itself well, even if it belongs to the circle of the most basic oils on the market.

Advantages

  • increased freezing point (-33 ° C) and flash (224 ° C);
  • high oxidation resistance due to the presence of appropriate additives;
  • retains its properties when fluctuating vehicle operating temperatures;
  • low cost, providing the proper lubrication and protection for the diesel engine.

Disadvantages

  • the predominance of high quality in the composition of the mineral base - hence the noticeable decline in performance when the resource is developed by 80%.

The best mineral oils for diesel engines

SHELL Rimula R4 L

Rating: 4.9

The second representative of the company SHELL, who managed to win the title of the best in the segment of diesel oils for general consumption. All the superiority of the Rimula R4 L is based on a simple formula: the company was initially set up to release the product under heavily loaded engines, working mainly in off-road conditions or having additional components (such as turbocharging). Having compiled all the requirements into a single concept, the engineers of the British company took up the improvement of three operational components: preventing increased wear, blocking the mechanism of formation of solid deposits, and also neutralizing acids. And, it is worth saying, they coped with the task perfectly.

Firstly, the SHELL Rimula R4 L protective mechanism operates in a wide temperature range: the complete crystallization of the oil begins at -33 ° C, and the flash occurs at 227 ° C. In addition, the kinematic viscosity when the engine is heated to the boiling point of water is 15.5 mm2/ sec - the best result among all representatives of the category. As a result, in terms of the combination of positive characteristics, this oil is the coolest of mineral oils, which confirms the high demand from consumers and the approval of experts.

Advantages

  • high level technical specifications;
  • development specifically for diesel engines operating in a highly loaded state;
  • alkalized composition, neutralizing the action of formed acids;
  • huge list of approvals and approvals (about 20 items).

Disadvantages

  • not found.

LIQUI MOLY MoS2 Leichtlauf 15W-40

Rating: 4.8

Unique mineral diesel oil for all-weather use, occupying one of the leading places in the ranking due to the complex of additionally provided functions and properties. The composition of LIQUI MOLY MoS2 Leichtlauf 15W-40, in addition to a high-quality mineral base and additives, was introduced molybdenum disulfide, which acts as an anti-seize, friction, noise insulating component. In addition, contributing to the cleanliness of the engine and actively counteracting deposits are also recorded in his asset, but it is also possible that these functions are performed by other components.

As the technical summary table shows, LIQUI MOLY MoS2 Leichtlauf 15W-40 has a high kinematic viscosity at 100 ° C - 14.5 mm2/ sec This means that the film formed during such heating of the oil is stable and does not lose lubricating properties, remaining intact and avoiding dry friction in the nodes. However, the amount of evaporation is a little confusing, which is (at run) 8.2% of the fill volume. As for the freezing point and flash point, these indicators are in the optimal range: -30 and 220 ° C, respectively. However, paying attention to the nuances, we say: the optimal level of cost compensates for all the shortcomings, and an additional component gives the oil uniqueness among the monotonous competitors.

Advantages

  • increased level of protection against wear of the rubbing parts of the engine;
  • active positive impact on the performance of new and old diesel models;
  • mineral oil is suitable for working with any modern systems;
  • excellent viscosity index when heated to the boiling point of water (14.5 mm2 / s).

Disadvantages

  • up to 8.2% of the total oil goes to evaporation.

Castrol Vecton 15W-40

Rating: 4.7

The right to close the top three went to Castrol Vecton 15W-40 engine oil, built on the basis of System 5 technology. It allows you to comprehensively increase the properties of the composition, affecting the most important working mechanisms: protection against oxides, the formation of sludge and sludge, increasing the efficiency of diesel engines, and also extends the life of the fill to 6 thousand kilometers.

With a collection of 12 approvals and approvals, the Castrol Vecton 15W-40 is performing well on important technical metrics. In particular, the overall purity of the oil is impressive in terms of the content of impurities: the amount of ash in the composition does not exceed 1.36% of the total mass. In addition, the pH is at the level of 10.5 units, which indicates a slightly alkaline environment and adaptability to neutralize acids formed in the process of fuel combustion. The final advantage of this "mineral water" can be considered high, even by the standards of synthetics, solidification temperature: crystallization of the oil begins to proceed at -42 ° C.

Advantages

  • System 5 technology allows the oil to quickly adapt to changing operating conditions (climate change, temperature and humidity fluctuations);
  • 12 official approvals and approvals (in particular, from MAN and Volvo);
  • active neutralization of acids and sediment solutions;
  • proven increase in engine power and fuel economy.

Disadvantages

  • quite expensive oil, faked in the secondary market.

The best diesel oils for winter

SHELL Helix Ultra ECT C2 / C3 0W-30

Rating: 4.9

Premium synthetic synthetic oil with a huge track record of positive effects when used in winter.The Helix Ultra ECT C2 / C3 0W-30 implements the Emission Compatible Technology, which allows for more thorough cleaning of the inside of the engine along with the lubrication of the most critical components.

Through various bench and functional tests, it was proved that this composition significantly increases fuel economy (by 2.6% compared to the reference sample within the framework of ACEA M 111), and also provides 2 times better cleaning of pistons from soot than industry requires norms. In fact, it seems that the SHELL Helix Ultra ECT C2 / C3 0W-30 marks the benchmark for the next few years, because other manufacturers do not yet express a desire to present products that are far ahead of the fairly stringent requirements of the standards. Together with a set of 10 tolerances and a full bag of experimental merit, this synthetics goes to the first line of our rating.

Advantages

  • 2.6% increase in fuel efficiency;
  • three times more effective protection against corrosion;
  • actively counteracting the formation of sludge;
  • extends the life of particulate filters due to the action of neutralizing additives;
  • optimal combination of price and quality.

Disadvantages

  • not found.

Motul 8100 X-max 0W30

Rating: 4.8

French oil with a modest (albeit representative) number of approvals and approvals (MB-Approval 229.5, VOLVO VCC 95200356, VW 502 00 - 505 00), which received mainly good reviews from consumers in Russia. 8100 X-max 0W30 was developed on a synthetic basis with a rich package of additives, and, most importantly, taking into account the difficult road conditions of Russia. As a result, it perfectly tolerates temperature fluctuations, does not freeze where other oils have long passed into a solid state of aggregation (-51 ° C), and also provides high-quality engine protection over the entire life cycle.

According to users, its resource is enough for a stable 10 thousand kilometers. However, in order to avoid triggering destructive mechanisms of sludge formation and corrosion, it is best to replace 1-2 times before the nominal value, especially on older, better-seen units. Thanks to a thorough study of the composition to maintain the flow properties in winter, the engineers managed to significantly increase the percentage of fuel economy compared to other products of the line (up to 1.7%). If you dive into the topic in more detail, then in the Motul 8100 X-max 0W30 you can see almost perfect indicators for all major and minor characteristics ... except for the price parameter. However, in relation to quality and durability, it does not seem negative.

Advantages

  • the freezing temperature is -51 ° C;
  • provides fuel savings of an average of 1.7% compared with reference samples within the main tolerances;
  • the operational period is 10 thousand kilometers;
  • good combination of price and quality.

Disadvantages

  • not detected.

TOTAL Quartz 9000 Energy 0W30

Rating: 4.7

Another synthetics is on the third line of the rating, this time by TOTAL. Once Quartz 9000 Energy 0W30 was the leader of the segment, but a series of falsifications and strengthening of the main competitors threw him into the ranks of "one of the best." Indeed, in its original form, this oil contributed to improving the efficiency of diesel engines (and significantly), and also optimized fuel consumption (by an average of 2.0%), while keeping the inside clean.

Unlike its main competitors, TOTAL Quartz 9000 Energy 0W30 is not a pure acid neutralizer - a pH of 8.8 hardly allows it to act effectively in such an important role. However, manufacturers corrected this situation by introducing special additives that interfere with the formation inside the engine of both solutions and acids and oxides. A good move, moreover, in all temperature operating conditions - from -45 to 226 ° C. If it were not for fraud, this composition could claim a higher place. But do not consider this an insoluble problem - since there are a lot of instructions on how to distinguish a fake from the original.

Advantages

  • beneficial effect on the diesel engine, increasing its efficiency by 1.5-2.0%;
  • excellent engine protection against carbon deposits and oxides;
  • lower cost than competitors;
  • ability to work in a wide temperature range under any driving conditions and roads.

Disadvantages

  • a large percentage of fakes in the retail market.

IDEMITSU Zepro Touring Pro 0W-30

Rating: 4.6

The composition is nominally of Japanese origin, corresponding to the strict requirements of Asian standards, and at the same time, perfectly passing according to the certificates of European manufacturers. IDEMITSU Zepro Touring Pro 0W-30 is very different from its competitors in the degree of purification from harmful impurities: less than 1% sulfate ash, up to 0.5% sulfur and 0.08% phosphorus. This degree of purification has a beneficial effect on the performance of the additives that make up the synthetic product.

Speaking about the safety of Japanese oil for diesel engines, it should be noted that it is completely neutral in terms of alkaline number: pH 7.84 does not harm the details of the unit, but it is also unable to neutralize acids. Fortunately, for this the base was stuffed with a large number of modifiers and other elements, the action of which was intended for cars with modernized diesel engines. Another advantage of IDEMITSU Zepro Touring Pro 0W-30 is expressed in its low freezing temperature: the oil is excellent for regions where frosts often exceed the -40 ° C mark. As a final fact, we note that the guaranteed working life here is 8 thousand kilometers or 300 hours (hours of engine operation).

Advantages

  • the actual absence of fakes in the market;
  • the resource is estimated at 300 hours or 8 thousand kilometers;
  • Composition complying with stringent Asian standards
  • very high degree of purification from harmful impurities.

Disadvantages

  • high price.

Castrol Edge 0W-30 A5 / B5

Rating: 4.5

Synthetic-based universal motor oil capable of working in gasoline and diesel engines created using modern technical solutions. It was based on the TITANIUM FST technology, the essence of which is the introduction of titanium-based additives into the composition. Active particles of this additive significantly increase the resistance of the oil to various influences, and also allows you to maintain the viscosity and integrity of the oil film in the entire range of operating temperatures.

Despite, in general, a mediocre flash point, Castrol Edge 0W-30 begins to freeze at a whopping -60 ° C. This allows the composition to work out without problems in conditions close to the Far North, where the leading role is given to concentrates and other potent technical fluids. Among other things, it should be recognized as one of the cleanest in this collection: the content of sulfate ash hardly exceeds 1% of the total mass. Unfortunately, the emphasis on versatility has hidden a significant amount of the working resource, which is so necessary for normal and long-term operation in a diesel engine. In fact, production here begins already at a run of 7 thousand kilometers, and in value terms this is not the best result.

Advantages

  • freezing temperature is at the level of -60 ° С;
  • a sufficiently high degree of purification from harmful impurities (not more than 1.18% sulfate ash);
  • the presence of a titanium additive (TITANIUM FST technology);
  • high quality of work (at least in the first period of operation).

Disadvantages

  • in diesel engines, universal oil has a reduced service life.
