Synthetic motor oils - choice. What is it - ns synthetic motor oil? PJSC Synthetic oil

The use of fully synthetic engine oils allows you to contain an engine clean, which is especially important for modern high-mounted engines.

Benefits of Synthetic

The first to fully appreciate the work of motor oils based on the synthetics, there were racing drivers. During the competition, the engine can work out its resource for one race: the pilot does not regret it, trying to squeeze out of the forced motor everything is capable of. And here, how it is impossible, by the way, the special properties of the oils of this type, which we have not yet affected our story. We list them.

High antifriction properties;
Fuel economy due to reducing friction;
Stability of engine parts to temperature overloads;
Low oil consumption on the avgar;
High resistance to oxidation during operation.
All this allowed to squeeze the maximum from the engine, and at the same time get to the finish line.

From the sports "stables", the synthetics began to move on and on civilians until it was unnoticed by the NS synthetics.

The reverse transition from the NC synthetics to the Synthetic is already possible from a new level of understanding that the user acquires from this transition. After all, in addition to the above qualities, relevant to the motorcycle, a simple user receives a few more advantages in the daily operation of the machine. Here they are:

Stability of chemical properties, during the entire period of use;
Engine cleanliness due to high detergents;
Confident engine start at low temperatures;
An elongated interservice interval.
Obviously there is something to fight.

Oil for perfectionists? ...

When you speak with the specialists of the oil industry on the issues of fully synthetic motor oils (this is another commonly used name of the synthetics), everyone says that this product is positioned as oil for perfectors and fans to drive. Taking their opinion, I was in the depths of the soul, I experienced some kind of dissonance, and during the preparation of the article, finally, was able to flexing it. I realized that I did not agree with them. I do not agree, first of all, with such a narrowing target audience. Of course, if you love to drive, without so-synthetics do not do. But it is not only the oil for lovers to buy the most expensive.

Synthetica - product for leaning!

I will explain my position. Synthetic is more expensive than NS synthetics, but not much - it is 30%. In almost 30% of this, it almost doubles it in thermal stability, without taking into account additional positive properties. It allows you to protect the engine and avoid its increased wear, increase the interservice mileage and, ultimately, get best condition Engine during operation. This leads to the economist on a possible serviceand fuel. Moreover, the use of similar synthetics is particularly relevant for modern thermally loaded engines, which also constructively alone oil canals. After all, the channel was clogged, and the engine "Cover". When using fully synthetic oil, such developments are excluded.

How to buy like synthetics?

The question that is apparent banal in the era of the winning capitalism, but relevant when making a purchase. As a simple consumer found on the "collapse" of stores synthetic oil, not oil made using hydrocracking technology?

Unfortunately, we can state that this is a difficult task. Russian consumer legislation does not distinguish between these two types of synthetics in contrast, for example, from German. The sites of oil producers on their pages tell about everything that is used, except as which base oil is used. Information on the base of oil has to look for as well as information about the composition of food additives in products - there is a read text written by small font on the label.

We give some simple recommendations, how to independently deal with inscriptions on the canister with butter. Thus, European oil producers tend to refer to the oil specification, which is done on National Assembly (hydrocracking) or write that "NS-Synthetic" oil. Veryship is like Japanese, Korean and American oil producers are boldly called their own, in fact, mineral or hydrocracking oils 100% or Full Synthetic. It is possible to figure out which oil is in the canister, it is possible only to a complex laboratory. But there are a few small things for which you can pay attention when choosing an oil:

If the oils are manufactured in Germany, then the "VollSynthetisches" inscriptions are usually enough, since Germany is the only country where the concept of synthetic oil is legally determined.
If the label is written "ns-synthetic" or "ns", these are oils produced on the basis of hydrocracking, and are not PJSC synthetics.
If the oils go in gradation 0W-, then their basis is in most cases synthetic.
Real synthetic oils cannot cost 450 rubles per liter. PJSC-based oils from Bardahl (Bardahl 10W60, Bardahl 0W40, Bardahl 5W30 Technos Exceed, Bardahl 5W40 Technos Exceed)

Most car enthusiasts do not consider that synthetic lubricants are the perfect solution for engines. However, almost none of them know that synthetics is classified into two large groups, depending on the base, is the NA and PJSC.

What is PJSC and NS Synthetic?

The designation of the NA on the package suggests that the grease base is oil produced by hydrocracking technology, and heavy petroleum products perform the raw materials here. Hydrocracking removes harmful additives from the mineral base and allows you to destroy long molecular chains.

But PAO synthetics are made of gas, conducting synthesis of light hydrocarbons of polyalphaolefins. Technology allows you to get a product without sulfur and metal impurities.

Many people think that there is no difference and most importantly - viscosity. However, exploitation vehicle proves the opposite. Oils with different bases are distinguished by thermo-oxidative stability.

Today, experts are increasingly recommended to reduce the interservice oil replacement intervals. The thing is that in major cities, traffic jams, machines work with overloads, and talk about ideal operating conditions in this case Not falls.

What are the advantages of paos synthetics

NS synthetic is cheaper due to features in technology. But the replacement interval is not very large here, although it is possible to find oils with an increase in 30% interservice mileage (it all depends on the manufacturer and additives used by them).

But if you go to the "full" synthetics, that is, on PJSC, the engine (including modern highly functional) will be contained clean much longer.

By the way, it is such oils that exclude racers, on each highway, squeezing the entire resource from its engine.

The advantages of PJSC synthetics are as follows:

• Increased antifriction characteristics;
• Decline in friction in working areas leading to fuel economy;
• Stability of engine elements when exposed to high temperatures;
• Minimum consumption for avgar;
• Increased oxidation resistance;
• Stability of chemical properties of lubrication throughout the entire operational period;
• Increased detergent properties that ensure the purity of the engine;
• Quick running motor even under reduced temperatures;
• Increased interservice interval.

For some reason, it is believed that completely synthetic oils (PJSC) are designed exclusively for fans of a speed driving. However, this product is designed primarily on those who protect the engine and their own funds. So, PJSC synthetics is more expensive than NA oils by 25-30%, but in thermal stability, it exceeds it. As a result, fuel economy and reducing service costs are obvious.

How to choose a PAO-synthetics?

Domestic legislation does not distinguish between PJSC and NA oils. Information about the type of basic oils used is difficult to find on the sites of manufacturers.

However, there are several little things to pay attention to when choosing:

• In Germany, the difference between synthetic oils is determined by law - here the inscription "VollSynthetisches" indicates a lubricant to the PJSC group;
• But the inscriptions on the "NS-Synthetic" or "NA" package indicate belonging to a completely different group;
• Oils classifying as 0W-, for the most part, have a synthetic base, and lubricants of categories 5W-, 10W-, 15W-, 20W almost always hydrocracking;
• The cost of fully synthetic oil is not lower than 6-10 dollars per liter;
• Among the large number of manufacturers you can find companies that make differences between these two groups of oils.

Features of using fully synthetic oils

There are several misconceptions about fully synthetic oils:

1. It is believed that due to the fluidity of such a lubricant in the engine may occur. In fact, the leaks are caused by the worn out elements of the motor, such as glands and seals, and much more often occur when driving on mineral water.
2. Synthetics can not adversely affect the engine - and if it only passes the running, and if it warranty period It has already ended. However, for this, it is necessary to comply with the service intervals of the replacement and use the grease of regulated viscosity.
3. The statement that synthetics is only needed by machines operating with extreme overloads (for example, in taxi mode) erroneously. It can be used on a car of any type - the main thing is to choose the viscosity correctly.
4. In a fully suitable engine, the synthetic almost does not require level control, since the avgar here is minimal compared to mineral lubricants.
5. It may seem that the cost of synthetic is overestimated, and there can be no choice of any economy. Yes, such lubricants are really more expensive, but their operating parameters are just talking about economy. So, quick start in the cold, improved lubrication in the work areas lead to a decrease in fuel consumption. In addition, this oil retains the working capacity longer and it does not need to top.
6. In the engines S. big mileage You can replace mineral water on the synthetics. In addition, in this case will happen soft flushing Motor from sediments of various origin.
7. With a high cleaning ability of synthetics, another delusion is connected, stating that "as soon as the oil has acquired a black color, it needs to be changed immediately." Fresh synthetic lubricant can really darken quickly, but it only speaks that the detergent additives in its composition work. But on diesel enginesworking on domestic fuel, oil will always be black, because in a diesel engine an increased amount of soot and sulfur connections.

Anyone motor oil - This is a mixture of base oil and additive package. Now the base oils is customary to share for five major groups.

First group - An ordinary mineral water derived from severe oil fractions in the presence of various solvents.

Second group - Improved mineral oils that have passed the procedure of hydroprocessing, increasing the stability of the base oil, and better purified from harmful impurities. They have their own niche, mainly in the area cargo transport, heavy ship and industrial diesel engines - they are used where the costs of oil are huge and the use of expensive synthetic ruin.

Third group - Basic oils obtained using hydrocracking technology (NS-technologies). On the Internet forums "SPEY" contemptively refer to these oils "Kryakak", although they occupy the bulk of the market. Some firms are positioning them as semi-synthetic (although they themselves recognize the incorrectness of the term "semi-synthetic"), some call ns synthetics. In essence, it is also mineral oil obtained from the corresponding oil fractions, but improved - and by the degree of purity, and in the molecular structure.

Fourth group - Full Synthetic, or fully synthetic oils. Their base is polyalphaolefins (PJSC). PAO molecules are a purely synthetic product that results in chemical reactions Mostly of oil gases - ethylene or butylene. Such oils are "collected" as a constructor, and therefore their properties are more predictable than that of mineral water. Lack of PJSC - high price. Therefore, go into the course of small tricks: why not mix percent twenty-thirty-forty PJSC with "crack" and not to call such oil completely synthetic? After all, the share of PJSC in the synthetic is not negotiated! Cunning can be solved only by flash temperatures, which is indicated in technical description Oils: PAO It seeks to 250 ° C and even higher (sometimes 280 ° C), and in pure NS synthetic - about 225 ° C.

Fifth group Basic oils combines all that did not fall in the first four. And the main one in this group and gained active distribution in the production of commercial oils is the basic oil based on estrices.

Estheri. - Fully synthetic compounds obtained from oil, but mainly from vegetable raw materials, mainly of rapeseed oil. This is a purely synthetic product, characterized by full stability. Its molecules have a charge, thereby sticking to the metal walls and confidently reduce wear. Unfortunately, it is impossible to make an oil consisting of some estrices: friction losses will be great. Therefore, the oil of the fifth group is also a mixture, most often the estrices and PJSC, but at the same time, since for clean synthetics, part of the operational properties is obtained at the base oil assembly stage, the volume of the additive package can be significantly less.

WHAT'S NEW?

The coolest group is the fifth, from which we took three estricular oils, each with their raisins.

CUPPER SAE 5W-40 FULL ESTER

The most Esters, if you can say so: according to the manufacturer's application, it contains up to 80% of the estants and only 2.5% of additives with special metal plasters (FR. Laquer - cover) components.

Xenum WRX 7.5W40.

Ester with microcracial additives based on boron nitride. Actually, boron nitride is a powerful abrasive, but there is a very small fraction, which is approved, is an analogue of solid lubrication in friction zones. We note the non-traditional, "fractional" class on SAE and a considerable price.

KROON OIL POLY TECH 10W-40

Here the so-called OSP technology is applied here, in which up to 30% of special polyesters - polyalkylene glycols (PAG) is included in the base oil based on PJSC and Esters. They are completely dissolved in oil and contribute to the best dissolving package of additives. We note the high viscosity index of the PAG (over 180 units), which provides good starting properties at low temperatures. approximate price - 5000 rubles for 5 liters.

The company to Estera took a curious couple from the third and fourth groups.

Totek Astra Robot 5W40

Ravenol HCS 5W-40 API SL / SM / CF

This hydrocracking synthetics will take place per point of reference. The price is ridiculous.

Test task - see how these oils work in identical standing conditions: what to wait and what to hope for? At the same time, we will not compare the oil of the fourth and fifth groups among themselves: they are not competing, but the principles of the development of the directions of modern "oil building".

Long race

Almost all the oil producers declare energy-saving functions, reducing wear, exceptional purity of parts, as well as an extended oil resource. It is possible to check and compare it only in the course of long bench tests that provide identical working conditions for each product. The technique is rolled.

The heart of the research plant is a stand engine based on the VAZ-2111, and the conditions of oil work in it are specifically tightened. In particular, the compression ratio is increased and the oil cooling was introduced: the oil is heated additionally. Samples were investigated in the chimmotological laboratory of the department of engines, cars and tracked machines of the St. Petersburg Polytechnic University and in the North-West Experts Center.

In such conditions, each oil was 180 hours in mode, characteristic of the movement of the car on the highway ( normal car There would be about 15,000 km during this time); Is that the number of start-up launches we had significantly less.

In the course of the test, we selected oil samples to track the history of his aging. In parallel, the power, fuel consumption and exhaust toxicity of the exhaust gases were measured. After each cycle, the motor disassembled to assess its condition - in particular, the degree of wear.

Mucing of hydrocracking

The first in the stand engine flooded the oil, designed to set the initial reference level. This is the Ravenol HCS 5W-40 NS synthetics. Everything was fine, but after 130 hours after the start test, the viscosity fell over the upper limit determined by the claimed class on SAE (16.3 CST), which is always equal to the formal failure. Mileage (in terms of) - a little more than 11,000 km. A sharp increase in viscosity and determined the noticeable deterioration in the engine characteristics: the power decreased by 3%, the fuel consumption increased by 7%.

Fourth will you?

The fourth group of basic oils in our test was the "most" synthetic engine oil - "Totk Astra Robot 5W40". And, you must admit, very successful. Against the background of hydrocracking oil, the advantages of complete synthetic on the basis of PJSC were clearly visible.

FirstlyThis is a resource. Conditional 15,000 km oil worked easily, its parameters remained within the specified. The pace of aging even in the proposed harsh conditions turned out to be noticeably lower than that of the "junior" groups. AND motor characteristics At the end of the tests were not too different from the initial.

SecondlyThis oil surprised with its low-temperature properties: -54 ºС - this is the temperature of freezing! High index Viscosity (under 170) provides a good viscosity-temperature characteristic that guarantees the optimal oil operation of both at high temperatures in loaded modes and when cold starts.

Ugra for the whole test cycle was minimal. The small volatility affected, which is indirectly confirmed by the highest outbreak temperature among all the oils of this group. As well as the results of measurements of the toxicity of exhaust gases: the yield of residual hydrocarbons is noticeably less than when the motor operation on other oils is not, that is, the oil, the toxicity component significantly decreased. How do we know what is the oil? From there, that the fuel component at the same gasoline and the same adjustments gives the difference only within the error.

The level of contamination in the engine is characteristic of the synthetic: small, but still noticeable.

Copper in oil

The first representative of the fifth group was the oil Cupper 5W40 Full Ester. The new original package of additives containing copper must provide metal-plastic properties. What does this mean? The working surfaces of the parts will form a thin copper film, smoothing roughness, as well as protecting friction assemblies from bully and wear. Lailed 15,000 km oil cut. After opening the engine, they saw that the surfaces of the cylinders began to resemble a veneer of Karelian birch - and color, and a pattern. This is copper. And the weighing of the parts at all shocked in shock: on the liners of bearings, instead of decreasing, a steady increase in the mass was observed! The minimum, at the level of several milligrams - but an increase! Does copper from the oil moved to the working surfaces of the liners? And one more miracle: alkaline number In fresh (to testing), the sample of the oil was only about 3 mg of con / g instead of the usual 6-10 con / g. Error? Run several times - everything is true! And after the test, it decreased only a little bit. That is what the combination of the ester base and the metal-plating package of additives gives. With rings cost without miracles, but the pace of wear is really less than on the reference hydrocracking synthetics.

The resource is worse than that of Totk Astra Robot oil on the basis of pure PJSC, but much better than the reference "hydrocracking". It is clear: additives work intensively, but there are few of them - therefore the oil resource cannot be infinite. But we remind: The conditional 15,000 km oil honestly worked.

Ester Engine Oil: White on Black

Ester-ceramic "Xenum WRX 7.5W40 oil with a microcramber gave a record low-low wear of the piston rings and cylinders, in addition, the rate of wear and bearing decreased. "Solid lubricant" from Bora nitride works! The energy-saving effect in oil manifested itself just where ordinary motors have to be particularly hard - in the maximum modes and what looks strange for non-professional, in mode idle move. In the first case, all details are valid maximum loadswhich should resist the oil. In the second, there are no loads, but also the speed of the relative movement of parts, forcing them to "float" on the oil layer, is very small. Therefore, not all oil works, but mostly his additive.

But without flying did not cost.

FirstlyThe rate of aging of this oil from the Estergroup turned out to be noticeably higher than the Cupper oil, Xenum lost even Totek oil from the PAO group. The test cycle is set aside, but the resource supply at its end was minimal. In our opinion, this is a consequence of more stringent conditions of oil film in the presence of ceramics microparticles. Focal local temperatures in friction zones, where solid microparticles work, can increase, and this is inevitably spoils the oil base.

SecondlyThe low-temperature properties of this oil also did not turn out to be ahti. However, non-standard "7.5" in the classification of SAE anything else and did not promise. And further. After the oil samples stood for some time on the shelf, they showed a poorly washed precipitate in them! Even a long shaking of the sample did not remove it from the bottom of the bottle. Miracles does not happen: ceramics - heavy, long to keep it in the volume of oil is impossible. Of course, the sediment was a bit, but it is somehow not in itself. Soothes only the fact that the oil in our market is not present for the first day, but no "horror stories" seems to be discovered.

Note that the sample color changed intensively. Initially, the oil reminded the color of the kefir: white-white. After 40 hours, it has already become like ordinary oil - dark, but the sediment is still whites. Bor nitride, however.

Poly Tee in Polytech

The tests were carried out in the Laboratory of the Department of Motors of St. Petersburg Polytechnic. How to pass by oil with such a familiar name - Kroon Oil Poly Tech? The only oil group of the Pag group as a whole confirmed what the description said. The main thing - when opening the motor after 180 hours of work in hard modes, we found almost clean pistons! There was actually high-temperature sediments, the zone of piston grooves was clean. And this means that the rings on this oil work normally, no surveillance is expected.

The level of low-temperature deposits was lower than that of other oils. It seems that the polyalkylene glycol base of oil dissolves them, as was promised by the manufacturer. And with the resource everything is fine: 15,000 km "passed" oil with a reserve for several more kilometers.

As for the resource of the engine and wear protection, everything is also very worthy, at the level of the best estricular samples and is much better than that of basic NC synthetics. But with the "cold" properties is not so unequivocal. Frozen temperature - under minus fifty, and this is one of the best indicators, but the viscosity index is not the highest. No wonder class 10W-40 by SAE.

Oils from the Future

Who said that all motor oils pour out of one barrel? During the test, we have made two important discoveries for themselves.

Firstly, ns-oils for their price work quite adequately and cannot spoil even the most modern motor.

Secondly, there are more interesting options than the most common third group on the market. And each of the considered oils has its advantages with a single minus - a high price. But for good and pay not sin, especially since the overpayment most often does not exceed the cost of one or two fuel charges. If you take into account the effect of energy saving (gasoline saving on average by 2-4%), improving car dynamics, starting properties and reducing the motor wear rate, then overpays does not look frightening.

Any of the oils that have tested by us can be easily pouring into the engine. According to our information, the same Xenum is very loved by riders. Cupper with his copper still seems in an inexplicable, but after all, it endured it! There are no questions for Owl Totek. And Kroon Oil Poly Tech polyalkylene glycale oil is generally diverted with a bang. In short, use boldly - of course, if the quality group of the selected oil is consistent with the requirements of the car operation instructions.

Our comment

Manufacturers of basic oils and additives - units, and therefore a variety of finite products is nowhere to ride. We have tested oils produce small volumes. On such products work out new solutions. Kroon Oil - the former daughter "Shell", Xenum is often used in motor racing, Cupper and Totk - new russian production. Take the oil to one or another group it is difficult: the manufacturer does not advertise its composition. The main part is ns-oil, the rest, approximately equally, are cheap mineral water (popular behind the ocean and in the Middle East) and the so-called complete synthetics.

Today we will take a little from the usual structure of such ratings - "Best mineral / semi-synthetic / synthetic oil". The reason is simple: a specifically taken engine primarily requires an oil viscosity by the manufacturer, and modern engines use low-grade lubricants (this is usually high-temperature viscosity 30, on many motors - 20). Discuss in this context something except synthetic, stupid. The separation of "oil for gasoline / diesel engines" is no less strange, given the fact that 90% modern oils have tolerances for use in both types of engines, discuss purely "diesel" oil in relation to passenger cars It makes sense only in the segment of oils intended for motors with summary filters.

Therefore, we divide the engine oils today by categories of their specific application, and not by virtual and not practical parameters:

• Oil with high temperature viscosity 40 (5W40 in our ranking) - the best way For engines produced in the 90s - the beginning of the 2000s. For the regions of the Far North, it makes sense to consider 0W40 oils, it can noticeably facilitate the launch of the motor in the winter.
• 5 W30. To date, it can be considered universal: this viscosity is also used in budget foreign cars, and in premium car engines.
• 0 W20. - low-grade motor oils used in large quantities modern engines. Moreover, pouring more viscous oils in them is categorically not recommended: piston rings specifically having reduced elasticity to reduce mechanical losses, do not cope with a more durable oil film, oil fumes begins.
• High temperature viscosity 50 Relevant for owners, rigidly operating their cars - no wonder oil 5W50, 10W60 got the name of "sports" in everyday life.
• 10w40 -the standard choice of older owners is usually the budget semi-synthetic of outdated quality classes - SH, SJ.
• Diesel with the particulate filters Must have a minimum inchar oil, which does not have a noticeable solid precipitate (low solitude). This parameter is critical, so only oils having appropriate certification are allowed into the motors of such cars. The overwhelming majority of passenger diesel engines use oils with a viscosity of 5W30, and we will consider them.

Often car owners do not know which oil is suitable for the engine of the machine. Such ignorance leads to the engine that lubricants are started into the engine, which do not meet the necessary parameters of the motor. Missing oil can cause engine overheating and subsequent repair.

Lubricating fluids are divided into the following groups.

1. Mineral oils. Such lubricants appear after the processing of some petroleum products. Have affordable pricesBut it is not suitable for all varieties of engines.
2. Semi-synthetic. Consist of a certain proportion of both mineral and synthetic lubrication. Operated in many cars.
3. Synthetic lubricant. Are considered one of the most high-quality oilsSince created by the synthesis of certain organic substances.

What kind of HC synthetic engine oil belongs to?

What is HC Synthetic Motor Oil? This question is quite popular in the modern automotive society. Motor oil, which has most of the HC synthetic component, is also called hydrocracking.

Lubricant, which consists of a HC synthetic component, has an increased viscosity and high-quality temperature indicators. Due to some additives that increase the characteristics, the viscosity index of such an oil can be increased to 175 units, given the fact that mineral lubricants are not increased over 100 units.

Considering the structure of the NC-synthetic engine oil, it can be concluded that it does not apply to the semi-synthetic group of lubricants. Hydrocracking lubrication fluid is almost 80% of the National Assembly, the rest of the percentage belongs to a different kind of additives. The semi-synthetic can not show such characteristics, so oils of this kind contain only 20-35% of synthetic substances in themselves, most of the mineral oil and several percent are reserved for additives.

Making conclusions, hydrocrack engine oil can be attributed to the synthetic group. This lubricant has a weighty advantage in price, as it stands several times cheaper semi-synthetic oil And an order of magnitude cheaper than synthetic.

What is hydrocracking?

To answer the question of what HC is synthetic engine oil, you should not climb the depth of chemistry, it suffices to understand the process of hydrocracking. Hydrocracking is not just a term, this is the designation of the whole technology that allows you to raise the technical component of petroleum products to a completely different level. This procedure includes processing and purification of mineral raw materials to the extent that it approaches the synthetic group. This means that hydrocracking oils, like mineral, is made from petroleum products, but in their structure refer to synthetic lubricants.

For the hydrocracking process, a certain hydrocarbon raw material is used, namely long hydrocarbon chains. Such chains are torn by chemical way, and after, the breakdowns are filled with hydrogen molecules. After the hydrocracking, a new substance is obtained, with a structure that is completely different from the structure mineral oils. This process is not just the purification and processing of petroleum products, but a type of synthesis.

To understand what hydrocracking is, look at this video:

Positive qualities of HC synthetic oil

What is HC-synthetic engine oil was described above, now it remains to know, indeed it can stand in one row with other synthetic oils.

The main advantage of hydrocracking oil is a high viscosity that will allow the lubricant on the surface of the rubbing parts, with this without losing fluidity. Also, such oils are insensitive to low temperaturesIt allows you to maintain the viscosity coefficient all year round.

Lubricating fluids with HC component do not cause harm rubber gaskets, seals and bushing. Such oils are not so sensitive to water intake. After dilution by some water, the hydrocracking oil will not spoil the components of the engine and the temperature process will not break.

There is such a concept as thermo-oxidative stability. This term denotes the duration of oil operation between its replacements. Basically, the oil change occurs when maintenanceConducted through a certain number of kilometers traveled. But the engine operation can be much more, as the car does not always go. You have to take into account traffic jams and warming the machine. It is with urban riding that thermo-oxidative stability is important. Hydrocracking oil is in third place on heat-oxidative stability, passing in front of him only synthetic.
