What is synthetic oil. What is the difference between mineral oil and synthetic oil?

Mineral engine oil on modern market is not very popular, many motorists prefer synthetics or semi-synthetics. However, most buyers are unaware that some famous brands sold under the brand of synthetics, a processed mineral mixture.

Mineral motor oils are a product of the processing of petroleum hydrocarbons. Their structure consists of molecules that are heterogeneous in shape and structure - this leads to instability of the characteristics of the motor fluid under various temperature conditions.

Mineral water, unlike synthetic and semi-synthetic lubricants, is of natural origin; natural additives are used for its manufacture. The structure of mineral mixtures manufacturers engine oils improved in two ways:

1. Removal of impurities from the liquid of harmful resins, acids, sulfur compounds. This method makes it possible to obtain an oil base without harmful substances, but the viscosity of the mixture at high and low temperatures will change.
2. More effective method Processing of mineral liquids is considered hydrocracking technology. Thanks to it, not only are removed from the base harmful substances, but the length of hydrocarbon chains also changes. Thus, the hydrocracking technology makes it possible to obtain products with stable viscosity characteristics to temperature differences. Hydrocracked oil will retain its properties better throughout the entire operating period (than pure mineral oil), it will practically not differ from synthetic mixtures.

Synthetic lubricants are obtained using the synthesis of hydrocarbon compounds, their cost is much more expensive than hydrocracked products. If you are looking to purchase a fully synthetic automotive oil, and not a mineral base processed product, synthetics differ in the designation in the classifications, and also note: the inscription on the "Full-synthetic" canister is fully synthetic.

Advantages and disadvantages

The main and most important difference between a mineral motor oil and a synthetic or semi-synthetic one is the resistance of the mixture to various temperature conditions of the power unit. In winter, mineral water begins to crystallize at very low temperatures and cannot ensure normal pumping of fluid through the lubrication system, as well as starting the drive without warming up. In summer, this engine oil thins when high temperatures ah overboard and cannot form a stable protective oil film on the engine elements.

Unlike other base stocks, mineral fluids do not contain additives necessary for the normal operation of most modern engines.

Synthetics and semi-synthetics differ from mineral water in the following characteristics:

1. Fluidity. Mineral water is too thick for use in modern engines.
2. Molecular structure. Heterogeneity molecular structure mineral mixtures leads to a decrease in their resistance to crystallization and liquefaction.
3. Additives. In synthetics and semi-synthetics, additives are better; they do not break down at high temperatures overboard. In contrast, for mineral water, additives of natural origin are used, which burn out at high temperatures.
4. The difference in terms of replacement, synthetics changes much less frequently.
5. Mineral water forms more deposits during engine operation.

Among the advantages of mineral motor oil should be highlighted:

1. These fluids work better in engines with high mileage. Unlike synthetics, which have large detergent properties, mineral mixtures do not lead to separation of carbon deposits from drive units and do not cause clogging of the lubrication system and motor channels. Mineral water washes carbon deposits from internal elements motor gradually.
2. Mineral water, unlike synthetics and semi-synthetics, interacts less aggressively with the rubber surfaces of the nodes lubrication system and drive, does not lead to their destruction.
3. Improves performance of worn power units. Mineral oils are quite thick, they are able to fill the increased gaps in the friction units of motors with high mileage.

Conclusion

Mineral motor oils in terms of viscosity characteristics lose to synthetic and semi-synthetic fluids. But there is power units, in which only the use of mineral water is possible, for example, only mineral oil or the drive has significant escape. In such situations, the use of synthetics or semi-synthetics is unacceptable due to the large amount of carbon deposits inside the motor.

When choosing mineral oil, consider the requirements of the car manufacturer, the type of engine, the base mixture that was previously poured into the engine.

Many motorists are constantly worried about the same question - how can you extend a reliable and smooth operation engine of your car. The key to answering it is correct selection And timely replacement high-quality engine oil is a task, the correct solution of which directly affects the life of the car.

How to make an informed and correct choice in huge assortment modern lubricants? How is mineral oil different from its synthetic "competitors"? What is the best lubricant and can its different types be mixed with each other? And finally - how to choose a quality, but not too expensive product? We will try to answer all these questions in one article.

Kinds

Modern materials, which increase the wear resistance of automotive engine parts, are divided into three main categories - mineral, semi-synthetic and synthetic oils. Consider each type of lubricant in more detail.

Mineral

It is produced from a natural mineral - oil, by distillation, distillation and subsequent refining. There are three main types of mineral oils, which differ in the composition of their hydrocarbons: paraffinic (the most suitable for the manufacture of lubricants), naphthenic and aromatic. Sulfur, which is part of the feedstock, increases the oxidizing properties of the final product, so its content in a high-quality lubricant should not exceed one percent.

Pure mineral motor oil very quickly loses the necessary properties, therefore, it is added to its composition a large number of various anti-corrosion, detergent and wear-resistant "additives". The material has a high viscosity, which allows it to be used in units that have a significant service life and “development” of sealing elements.

Synthetic

It's over modern look lubricants for an automobile engine, obtained by synthesizing certain substances. There are several types of these products: hydrocarbon, polyester, silicone, polyglycol synthetic oils, as well as oils made on the basis of phosphoric acid esters. Pretty complicated chemical production requires significant capital investments, therefore the product itself "at the exit" is much more expensive than its mineral counterpart.

Naturally, its high cost is offset by some advantages, namely:

• reduced sensitivity to overheating;
• maintaining performance properties at low temperatures;
• increased fluidity, which reduces friction between parts;

Synthetic motor oil practically does not oxidize, it can be used under conditions of increased engine loads and various temperature conditions.

semi-synthetic

The composition of this product includes mineral oils for the engine (or rather, their basic components), mixed with synthetic components in a ratio of 70 to 30. Such a lubricant is a kind of compromise between “mineral water” and “synthetics” - it has quite good operational characteristics, but it is not very expensive.

Characteristics of mineral and synthetic motor oil

Consider the main characteristics of lubricants for engines internal combustion, summarizing them in a simple and convenient table:

Now, having studied required parameters, let's try to answer the question in more detail, how does mineral motor oil differ from synthetic and semi-synthetic.

What is the difference

Mineral and synthetic

Already from the name itself it is clear that mineral lubricants are made from natural petroleum hydrocarbons, while synthetic lubricants are a product obtained as a result of chemical reactions. Why was there a need for a rather complex synthesis? It's all about the operating conditions of automobile engines - they are accompanied by a sharp change in speed, a difference in temperature conditions, a change in friction speed, and so on. The base base of mineral engine oil cannot always provide maximum stability for the operation of an internal combustion engine. Synthetic lubricants perform much better as they are less affected by external factors.

Let's take a closer look at what is the difference between mineral oil and synthetic:

• origin: the basis of "mineral water" is created by nature itself, "synthetics" is the result of molecular synthesis;
• reaction to a change in the temperature regime of the engine;
• preservation of the main characteristics during the operation of the engine: "synthetics" retains its main parameters much longer;
• fluidity: high degree the viscosity of mineral motor oil does not allow it to be used at ultra-low temperatures;
• change in the stability of the main parameters at high temperatures: some "additives" in the composition of mineral grease can simply burn out.

So, the main difference between “synthetics” and mineral motor oil is the higher stability of its characteristics and properties in various temperature conditions, as well as the service life of the units.

Mineral and semi-synthetics

Being a product obtained by mixing two bases, "semi-synthetics" has more high performance stability compared to mineral motor oil, somewhat inferior to synthetic. It is more often used in cars with significant mileage, which are operated at temperatures not lower than 20 º C.

Which oil is better

Now let's answer another important question - what kind of oil should we choose, mineral or synthetic? It seems that synthetic lubricants have an undeniable advantage over their mineral counterparts, but let's not forget that everything in our world is relative. The fact is that the use of "synthetics" is not always an urgent need. For example, we know that platinum conducts better electricity than copper, but this does not mean that the wiring in our apartment should be made of platinum elements. Copper wires are quite enough for using household appliances.

In certain cases, the use of "synthetics" for engine lubrication is generally contraindicated - this applies mainly to units with high mileage. The sealing glands in them, as a rule, are very worn out and a synthetic lubricant with high fluidity will not be able to provide normal work motor - it will quickly leak out or evaporate. If your car is released domestic manufacturer and has a significant service life, do not hesitate - feel free to purchase Russian mineral oils "LUKOIL", "AZMOL" or "TNK" - the quality of these products can ensure reliable protection engine.

The advantage of mineral motor oil is also its ability to gradually “wash off” deposits on internal combustion engine elements, while fluid "synthetics" simply "scrape" them. At the same time, oil lines and filters become clogged with large fractions of soot and soot. If you operate your car in a region where the temperature in winter does not fall below 20-25 º C, then there is an urgent need for mandatory use synthetic lubricant No.

The main thing here is that all the main parameters of lubricants are suitable for your engine. The only point is that mineral or semi-synthetic motor oil requires more frequent changes. With proper fulfillment of this condition, no harm will be done to the engine from the use of "mineral water" and "semi-synthetics".

Attention! The replacement of mineral engine oil in the engine must be carried out at least after 5-7 thousand km of the car.

Is it possible to mix

At the end of our review, let's talk about whether it is possible to mix mineral and synthetic oil for DVS. This question arises, as a rule, when changing the lubricant in the motor or in emergency when you need to top up urgently. What to do if "at hand" was not the brand of engine oil we needed, and its level dropped to a critical level? As always, we listen to the advice of experts.

Most experts argue that mixing different types of oils in an engine is bad idea. They are sure that the formation of a "cocktail" of various additives contained in motor oils can lead to a chemical reaction with a mixture that does not meet any standards and requirements. However, the very fact of the existence of "semi-synthetics" proves to us that motor oils can still be mixed. Naturally, when performing these actions, you must comply with the necessary conditions:

Attention! When mixing motor lubricants use products from one manufacturer, and at the first opportunity, perform complete replacement oil and change the filter.

Mixing video automotive oils:

So, we still managed to find out if it is possible to mix synthetic, mineral and semi-synthetic oil without damage car engine. We also proved that the use of expensive high-tech motor lubricants is not always justified. We think that we have touched on a rather important topic that worries many car owners and we hope to reveal it in more detail in the following articles.

Today, among car owners, there is a lot of controversy about which oil is better to fill in the engine. Some prefer mineral liquids, others recommend taking it, and still others do not choose anything other than semi-synthetics. In addition, they create many companies that advertise their products as the most modern and optimal. In this article, we will consider several criteria for choosing lubricants and find out which oil is best to fill in the engine.

Viscosity

The first thing to pay attention to is the viscosity of the lubricant. Often, the characteristics of motor oils are divided into two types - summer (that is, those that should be filled in in the summer) and winter (well, everything is clear here). So, every manufacturer, be it Opel or domestic gas, initially indicate in the operating manual the exact one that needs to be filled in at one time or another of the year. There are no exact indicators here, since each company sets its own optimal data range, and the difference between them is very large.

Car mileage

The answer to the question of which oil is better to fill in the engine directly depends on the life of the machine, that is, its total mileage. Many masters recommend that motorists use synthetic oil only for new cars. Well, for the old there is nothing better than mineral liquids. Also worth noting an exception - if you are the host sports car, which is 5 or more years old, it is better to give preference to "synthetics", since the engine in such machines runs at very high speeds.

What was the liquid before?

An examination of motor oils showed that in many ways the choice desired liquid(in particular, on used cars) depends on what lubricant their engine was previously running on. For example, if over the past 50-80 thousand kilometers the engine has been running on "mineral water", then this time it is best to fill it with "synthetics". Why? The thing is that the first type of oil, in terms of its properties, forms various cracks and deposits in the units, which can only be washed out by the second type of lubricant (it has stronger acid indicators, so it is very useful for the engine). But it is possible that “synthetics” will also wash out useful deposits, so it should not be poured a second time. But then what kind of oil is better to fill in the engine after synthetic fluid? In this case, it is best not to immediately switch back to mineral water, but to use a compromise - a semi-synthetic lubricant. Thanks to its special properties, it will not harm the operation of the engine and at the same time prepare it for the next consumption of mineral water.

As you can see, there is no definite answer to the question of which oil is better to fill in the engine. Each car is special, and you only need to fill it with the liquid that will not inhibit the operation of the engine (we just listed these cases). Therefore, take care of your iron friend and pour only high-quality liquids into it!

With the advent of various types of oils, disputes do not stop about which oil is better to choose in the engine of your car. Each type of oil has many supporters, but often their arguments are based on myths, so choosing the type of oil in a car engine needs to be approached a little more thoroughly. Mineral or synthetic oil? Or maybe semi-synthetic? This article will show the differences between the types of motor oils, what is their difference and whether it is possible to mix lubricants of different composition.

Engine oil in the engine - purpose

The original purpose of motor oils is to remove heat from rubbing parts inside the engine, as well as, if possible, to remove metal particles that form during friction. By and large, nothing has changed for a long time, and on this moment these tasks are presented when choosing an oil. However, it is worth considering the fact that with the advent of semi-synthetic and synthetic oils on the market, motorists begin to actively argue about at what temperature regime ambient air they can be used. A large number of lubricant manufacturers and their properly aligned marketing companies to attract new customers only exacerbate the matter.

Mineral engine oil

For the production of mineral oil, agricultural crops are used or it is obtained during the processing of fuel oil and the subsequent purification of processed products. Since this technology is quite simple and for many years people have successfully tried to simplify this process, then this is due to low cost mineral lubricating oils. As positive effect from the use of mineral oil in a car engine can be distinguished high efficiency in use, hydrolytic stability and slight mechanical impact when interacting with moving parts of the engine. In addition, mineral oil can interfere with other identical and natural oils have an excellent anti-corrosion formation coefficient.

But all these positive properties mineral oils are often achieved within a comfortable temperature range of 10 to 25 degrees Celsius. The use of mineral oils at low or high temperatures requires the use of various additives. But this is the obvious disadvantage of using mineral motor oils: at high temperatures, additives burn out, and at low temperatures, the use of mineral oils is difficult due to their high viscosity coefficient.

Semi-synthetic engine oil

Such an intermediate type of engine oil can be obtained by diluting mineral oil with synthetic oil. Experts recommend using proportions of 50% to 50% or 70% mineral to 30% synthetic motor oil.

Synthetic engine oil

The coolant for the engine is obtained by the synthesis of molecules. So, during operation, synthetic oils show better stability indicators and do not depend so much on the effects of low temperatures. The choice of synthetic oil is desirable to be carried out according to individual parameters: the region of residence and the presence of high or low temperatures during the use of the car, the nature of driving and starting, etc. Of course, it is worth considering the fact that such oil cannot be found in nature unchanged, but it has become so firmly established in everyday life. modern life that people do not think about its origin. The price of synthetic oil is the most expensive of all the above materials, but in the presence of very low temperatures environment it is a necessity rather than a privilege.

The advantages of using synthetic petroleum products include:

• Increased anti-friction properties.
• There is practically no need to use additives, since the main part was added by the manufacturer at the production stage.
• Lower evaporation coefficient before mineral oil products.
• Use at low temperatures.

Advantages of various lubricant formulations over others

Synthetics and mineral composition - which oil is better: these oil products differ at the molecular level. The molecular structure of synthetics was achieved through long-term testing to achieve the required properties, and the molecular structure of mineral oil products was laid down by nature. If in some component synthetic oils are worse than mineral lubricants, then this is also over continuous work. But the fact is that mineral mixtures clean the engine continuously and with approximately the same efficiency, while synthetics, in turn, due to their viscosity, clean quickly enough. Because of this effect, oil filters and oil lines are literally clogged with particle deposits from the engine. In this case, with improper control of the elements oil system effect may appear oil starvation and subsequent engine failure.

Therefore, we can distinguish the main differences between the two main types of oils:

• different molecular structure.
• The different nature of the response of oils to changes in temperature, in this synthetics are much better than mineral ones.
• Different fluidity of oils: due to exposure to low temperatures, mineral oil becomes thicker, synthetics are much more versatile in use.
• Stability consists in the burnout of additives of mineral oil products, which leads to a change in the operation of the engine or its failure.

Mineral or synthetic oil? The answer will depend only on the car owner of a personal car.

Which oil is better: synthetic or semi-synthetic? What do the terms resistance and stability mean when using synthetics? This means that exposure to low or high temperatures practically does not reduce the viscosity, and hence the effectiveness of the oil for a long time. When choosing in favor of semi-synthetic oil, you should pay attention to the fact that in some cases its use is more reasonable than synthetics. For example, with a large impressive engine mileage, synthetics can give high carbon monoxide, as well as when using a car with comfortable temperatures V winter time year - up to -20 degrees Celsius. However, the replacement this oil needs to be produced more often than synthetic.

In addition to the molecular structure, oil products for engine cooling are usually broken down into seasonality of use: summer, winter and all-weather oil. Summer oil, due to its viscosity, is reasonable to use up to 0 degrees Celsius. Otherwise, there is a high probability that the engine will not be able to start or will fail. Marking of summer oils: SAE 20, SAE 30 and so on up to 60. The designation of the numbers indicates the viscosity of the oil at operating temperature engine, the higher the number, the thicker the oil when heated.

Winter oils are marked from 0 to 25 units with the prefix W - winter (winter). Discreteness through 5 units. The minimum threshold for the temperature regime used is determined by subtracting 40 units from a given number. For example, for oil products marked 5 W, the minimum temperature at which the correct pumping of the oil system is ensured will be -35 degrees Celsius. But for winter oil products, it is also necessary to know such a selection criterion as crankability. To determine this parameter, 35 must be subtracted from the given number, while it is safe to say that for 10 W oil, the lower limit for the safe start of a car engine is 25 degrees Celsius.

All season oils. Lubricant marking is indicated by a combination of alphabetic and digital notation winter and summer oil. As an example, 5W - 30 can be deciphered as follows: winter marking 5W and summer marking 30 says that safe launch engine can be produced at a minimum ambient temperature of -35 degrees Celsius and the maximum allowable viscosity with a working engine will be 30 units. What is the difference between 5W-30 and 5W-40? The whole difference lies in the fact that the first of the presented types of lubricants in summer period more than a season liquid consistency. Therefore, if in the region of residence most of the year is positive temperatures, then for the proper operation of the motor, it is necessary to purchase a lubricant with a higher viscosity. In winter, these oils will ensure uninterrupted engine start at -35 degrees Celsius. Viscosity table of motor oil classification:

small and useful advice on the choice of oil for a car from experts:

• Before purchasing a lubricant for your car engine, you should carefully read the recommendations for using a particular type of oil directly from the manufacturer.
• Storage of lubricants is allowed with a tightly closed container lid, which prevents air, moisture or other foreign objects from entering the used oil.
• The operation of more expensive oils is not always smart choice, this can lead to a violation of the stability of the entire oil system.
• Do not succumb to the tricks of sellers, and buy oil only hoping for their advice. It is necessary to understand that all lubricants, including mineral or synthetic oil, are produced using approximately the same technology. The whole difference lies in the quantity and quality of additives added.
• An oil change must be carried out within the time specified by the manufacturer in terms of time or vehicle mileage. However, one should take into account the fact that worn engine oil should be changed a little earlier. This is due to the need to remove more friction products and much harsher working conditions.
• Always change oil when changing oil filter, this operation costs little money, but helps to ensure high-quality filtration of the lubricant.
• Can you mix 2 different types lubricants directly in the engine? The unequivocal answer is no! This leads to the formation of an insoluble precipitate.
• Carefully monitor the condition of the oil level in the engine, do not allow it to go beyond the upper or lower limits, which are marked on a special dipstick.
• If synthetics are flooded in the engine (for example, 10W - 40 of a certain brand), then the best option is to carry a small container of the same oil with you in case you need to add it. However, it is allowed to add a lubricant from another manufacturer, but with the same marking.
• Occasionally clean the oil system of a car engine using special means and lots of oil. This allows you to completely renew the lubricant in the engine and completely remove metal wear products.
• Before purchasing a lubricant for an engine, you need to study its expiration date on individual packaging. Tip: to prevent the purchase of low-quality fake oil it is wiser to buy it from official suppliers or trusted sellers in sealed metal packaging. This does not exclude the possibility of forgery, but reduces it to a minimum.

Conclusion.

Now many inexperienced motorists will be able to replenish their knowledge base on whether it is possible to mix and what is the difference between various types oils. Which oil is better to fill in your car can be determined based on your knowledge of the properties and markings of these lubricants, as well as the nature of behavior at different times of the year, and not on the advice of annoying sellers and television advertising. And also determine the type of lubricant for cars with high mileage, because it is far from always expensive oil it is reasonable to use instead of a cheaper, but effective in a particular case.

Few people know how synthetic oil differs from mineral oil. Lubricants- an indispensable material for the operation of any mechanism with parts that experience friction during operation. Their function is to reduce the coefficient of friction. The need for lubrication appeared simultaneously with the invention of the wheel by man. The first was a mineral product based on oil refining, and later the production of synthetic lubricants began.

Synthetic or mineral water - which is better?

The main difference is the molecular level of these types of oils. In synthetic - the synthesis of molecules is carried out with their already defined properties, and mineral molecules are created by nature itself. The mineral product is obtained by distillation of fuel oil. Industrial crops can also be raw materials for such oil. The advantages of mineral oil include efficient operation and low damage to parts.

These positive traits appear only in the range of room temperatures and require the use of additives, so the use of such oils in their natural state is impractical. Synthetic analogues are obtained by synthesizing molecules. Such oils are characterized by stability and little dependence on the influence of environmental factors. same quality engine operation in different modes provide quality synthetic products. Therefore, the main differences between synthetic and mineral oils can be formulated as follows:

• different origin of molecules (synthetic and natural);
• different properties when the temperature changes, in this case, synthetic ones have an advantage;
• different degrees of viscosity (negative ambient temperatures are unsuitable for the use of mineral products);
• different degree of stability of parameters at different temperature conditions: at elevated temperatures in the mineral analogue burnout of additives occurs, which harms the operation of the engine.

An important task for modern motor oil is the purification of engine parts from the end product of combustion of the fuel material. When using mineral analogues, deposits are washed off parts gradually, and the high fluidity of synthetic oils makes it possible to more effectively “scrape off” sediment from them. It should be noted higher resistance to oxidation.

Today, engines cannot operate without synthetic oil, especially at low temperatures. But the cost of production of such oils is small, and their price is higher compared to mineral oils.

What is the difference between mineral oil and semi-synthetic?

Lubrication cleans the motor and protects parts

Semi-synthetic oils are a mixture of mineral oils with improved parameters that have undergone special purification and synthetic oils with additives that make up no more than 50 percent in the resulting mixture. Semi-synthetic oil has better performance properties than mineral. Its price is lower than pure synthetic. Semi-synthetic has the same benefits as synthetics: improved viscosity at high and low temperatures, reduced product loss due to evaporation, extended engine life.

Currently, it is semi-synthetic oils that meet the requirements of car owners due to additional protection from elevated temperatures and sludge, easier starting of the engine at low (-40 ° C) temperatures and fuel savings from 2 to 5 percent due to reduced friction. The advantages of a semi-synthetic analogue over a mineral one are as follows:

• more than high index viscosity;
• reduced evaporation capacity and a slight tendency to form deposits when elevated temperature, which makes it possible to use them when operating vehicles in hot climates;
• the presence of higher antioxidant, dispersant properties and mechanical stability;
• a significant period of use before its replacement and reduced consumption during operation gives savings of up to 40 percent;
• reduced fuel consumption as a result optimal mode friction parts.

Every car owner faces the problem of choice the best option engine oil. As practice shows, semi-synthetic products are the best combination prices and quality indicators. When selecting oil for a particular type of car, you must first take into account its 3 main characteristics: tolerances, viscosity index and API standards.

If operation vehicle will be held in climatic zones with low temperatures, That perfect choice will be fully synthetic oils. Their prices are higher than for semi-synthetics, but the main advantage will be the ability of the engine to work in cold climates. The use of semi-synthetic motor oils will help to increase the period of efficient operation of vehicles.

These oils are recommended for vehicles with high mileage. In terms of price, semi-synthetics occupies an intermediate position between mineral and synthetic oils. Information about quality indicators can be obtained by reading the rating different brands semi-synthetic engine oil, as well as consumer reviews using certain options from different manufacturers.

The final choice between synthetics and semi-synthetics, of course, remains with the owner of the car, who at the same time takes into account all the standards and tolerances of the engine of his car. Semi-synthetic oil tends to be the best and economical option for those looking to extend their life. effective work engine.

Vehicle specifications and oil

When deciding on the choice of the type of product, first of all, it is necessary to have full information O technical specifications both car and engine. It is necessary to study the provisions of the vehicle operating instructions, which indicate the recommended product viscosity for various seasonal conditions. The degree of deterioration of the motor is also taken into account, and what kind of oil was used in it earlier.

If mineral analogues were used for several years, the resulting deposits filled the cracks in the rubber, which remained in them when the oil was changed. If synthetics are poured into such a motor, then thanks to its acid characteristics erodes such deposits, which often leads to its leakage through the released microcracks.

Therefore, it is recommended to use synthetics for new engines, as well as engines with high speed (sports cars). For an old engine, more frequent replacement mineral oil. Choosing a semi-synthetic will be a reasonable compromise between mineral and synthetic. For a motor in which only mineral products were used, this option would be non-critical, provided High Quality selected semi-synthetic oil.

Individual approach

Oil selection is a completely individual process. It takes into account the brand of the car, its mileage, the condition of the engine, the types of fuel (gasoline or diesel), the season and the operating conditions of the vehicle. Eat general recommendation for oil change in normal conditions operation after every 10 thousand km, and according to general opinion leading automakers about recognizing the conditions in Russia as difficult, it is better to change the oil after 5 thousand kilometers.

For diesel engines More frequent oil changes may be recommended. We advise you to follow the replacement periods recommended by the manufacturers, since the formation of combustion products does not improve the performance of your car engine. Widely known among consumers is the product of Mobil, which belongs to synthetic motor products. This type contains additives that increase the elasticity properties of engine seals, which help to avoid possible oil leakage.

The use of synthetic motor oils is provided for all types of vehicles, regardless of the region of operation and any load class. At the most difficult conditions operation, the advantages of synthetic analogs over mineral ones will become more and more obvious. The assumption of a greater consumption of synthetics, compared with mineral ones, turned out to be erroneous, since waste is the result of decomposition of the base mineral base.

Hence, fundamental difference between mineral and synthetic product will different technology their manufacture, as a result of which these oils have different properties. Synthetic ones have a more stable molecular network, which makes them more efficient under high loads and does not cause sludge and varnish deposits to fall out. Mineral analogues have a limited period of use and do not allow violations of their replacement period.

The general advice for motorists is the following: you need to purchase only the product, the quality of which does not cause concern. It is better to use products from a well-known manufacturer.
