Hello everyone! With the arrival of cold weather, becomes a topical question, how to choose winter oil For the engine. On the one hand, it's easy, and on the other - there are some nuances. If you pour the first liquid or thoughtlessly follow the advice of the neighbor - you can harm the motor. Why is that? Let's deal with.
Do I need to change the oil in the winter
At minus temperatures, the engine is most demanding about the quality of the oil. The smaller the viscosity of the lubricant during the cold start - the better. Just B. winter time There is an effect of oil starvation of the engine. What it is?
As you know, when starting, the oil should be filled with the engine. The faster it happens, the better. Because For a while, the motor has to work almost on dry. And when, inside the engine, the metal runs about the metal - there will be nothing good.
Naturally, the thick of the engine oils - the harder it is crushed through all the details. In addition, the load and on the battery. Not in vain, most failures rechargeable batteries It is for the winter. Not only that it itself loses up to 40% of the capacity with a strong frost, it is also an additional load in the form of thick lubricant.
To fight it, you need to apply high-quality winter or all-season lubricant, which will be stable when low temperaturesoh. Therefore, all experts recommend changing the oil before the onset of cold. Even if a few more thousands left to the planned replacement - it will be justified. Especially if under the hood flooded a liquid with a low low-temperature viscosity.
What is the viscosity of the oil
- This is its main characteristic. It defines the maximum permissible temperatures in which the lubricant retains its properties. If the car is operated in a gentle mode, in the warm climate - you can not pay special attention on viscosity. The engine will feel well on any all-season lubricant.
But when the machine is used with extremely low or high temperatures - viscosity needs to pay special attention.
What is viscosity? In fact, this is the ability of oil to create a lubricant between the parts of the engine. Here is a simple dependence:
- high viscosity - film thicker;
- low viscosity - film thinner.
Basic viscosity requirements:
- it should not be too high - the lubricant layer on the details will be too thick and the engine will work heavier - as a result increased flow fuel;
- it should not be low - a layer of lubricant will succeed in thin - as a result, it is possible to try the engine parts and its rapid wear.
Therefore, the viscosity of the oil must be optimal. It should be understood that the concept of optimality for each engine will be its own.
Viscosity index
Very interesting and most importantly important parameterdefining the operational characteristics of lubrication. Let's deal with it more.
When the engine works, it is heated, and the viscosity of the oil drops. Those. It is diluted. The dependence of the rate of ignition of oil and is its viscosity index.
From here you can get such a dependence:
- the higher the index, the oil loses the thickness slower, and accordingly the engine parts are better than blurred;
- the lower the index, the way it is diluted faster. In this case, the lubricant becomes thinner and the engine wear increases.
In a sense, this parameter is a characteristic of lubrication stability. Those. Determines how well it works at extreme temperatures. To select winter oil, it means that the higher the viscosity index, the easier it will take the cold start of the engine.
Unfortunately, manufacturers do not indicate the canister. But, it will not be superfluous to know their average characteristics for different species Oils:
- Synthetic - 140-170.
- Semi-synthetic – 130-150.
- Mineral - 110-135.
As you can see, the mineral car has the lowest. What is not surprising - it's no secret that these lubricants turn into Kissel in the cold.
The highest synthetic indicator, but unfortunately, it can be used on new engines. Motors with large runs are no longer so good tolerant.
SAE motor oil classification
On each canister oil there is a marking of its viscosity on SAE. For example:
- 10w40;
- 15w40;
- 5W30, etc.
What do these figures mean, and how to understand what oil is better to pour into the engine for the winter? Let's deal with.
There are 3 types of lubricant:
- Summer.
- Winter.
- All-season.
It is worth saying that all-season fluids, practically crowded summer and winter oil. Still, it is inconvenient to depend on the weather and change the lubricant when winter or summer comes. Moreover, all-season fluids provide stable work In a wide temperature range.
Justice, it is worth noting that there is:
- 5 year old grades - 20, 30, 40, 50, 60;
- 6 Winter - 0W, 5W, 10W, 15W, 20W, 25W.
All-season fluids are marked up as follows: 10W40, 5W30, etc. The cyfra in front of the letter W (WINTER) denotes the lower temperature limit at which the engine lubricant is provided during cold start. The digit after - refers to work at the plus temperatures.
By the way, it is not necessary to believe that these numbers are equal to the extreme temperatures of oil. Everything is more complicated. And soon we will deal with it.
Temperature modes
Let's see what they mean sAE marksand in which temperature modes can be used. For clarity, take several oil brands:
- Mobile super 5W30 - provides engine lubrication at temperatures up to -30 degrees;
- LUKOIL GENEZIS POLAR SPECIAL 0W30 - real extreme, fluid is able to withstand the temperature in -40 degrees;
- ZIK A + 10W30 - Universal All-season oil, will provide a good cold start at temperatures up to -25 degrees
- Mobil Ultra 10W40 - Liquid with a higher value high temperature viscosity It is better to use in warm regions;
- Castrol GTX 15W40 - for cold winters no longer suitable, the temperature of the cold start to -15 degrees.
Thus, you can easily determine what kind of engine oil for the winter suitable better.
Oil choice criteria
To determine what kind of oil is pouring into the engine for the winter, you need to take into account several criteria. Among them:
- recommendations of the car manufacturer;
- mileage cars;
- terms of Use;
- driving manner;
- fluid specifications for ACEA API, as well as tolerances.
In order not to climb into a technical debrist, you can use the selection of oil on the car brand. Let's not stop at this. It is enough to know that on the Internet there is a bunch of services where you can make such a selection.
Motor Motor Main. All aggregates are distinguished by their device and nuances of work. Therefore, first of all, you need to pay attention to the recommendation of the plant - the manufacturer knows best of all, what oil pour into the car. Well, on tolerances, if they are, of course.
For example, the oil recommended for the car is 10W40. If you board 15w40 - the pump will be more difficult to pump fluid in frost. If you change on 0W20 - the motor will start working for wear, because Too fluid lubrication is unable to provide good lubricant Motor.
Mileage and motor status
As you know, when the car moves a mark of 60-70 thousand, it is recommended to move with synthetics to semi-synthetic. This is caused by a decline performance characteristics Motor. Therefore, to determine which oil is better suitable for the motor, it is necessary to take into account his condition.
With the increase in the mileage, the engine changes the requirements for lubricant thickness. And it is recommended to use oil with more high index High temperature viscosity. I am expressed by a simple language - you need to pour the liquid thicker than before. In worn motors, also better not pour too liquid oil - due to increased gaps, the lubricant will flush with parts.
But, here is a stick about two ends. Too thick lubricant will kill the engine in the frost. Therefore, good engine oil for the winter should be a compromise solution.
If you listen to specialists, they advise:
- when the machine is run, more than 100 thousand, all-season use 5W40, and in winter 5W30 and 10W30;
- when running more than 250 thousand, all season use 5W50, and specifically for winter - 5W40 and 10W40.
But, again, even when large runs The engine can be in very good condition, as well as be killed after 50 thousand. Therefore, the mileage needs to be considered only together with the general state of the motor.
API standards, ACEA and tolerances
Everything is simple here - to understand what oil is pouring, you need to check the tolerance. If it has a liquid - it means the car it is suitable. If you do not know what a tolerance is, then I will explain. This is a special labeling on the canister, meaning that the oil passed internal certification from the car manufacturer and allowed by them for use in motors.
Concerning aPI standards And ACEA, it is also not difficult here. These standards determine the compatibility of the motor with a lubricant. So, by API (American Standard):
- Marking "C" - for diesel engine.
- Marking "S" - for gasoline engines.
- "S \\ C" - universal liquid.
For example, the Marking SL / CI-4 - indicates a universal oil, suitable for both diesel and petrol engines. The second letters on the marking, talk about quality. The closer to the end of the alphabet, the later the specification was adopted - and therefore the liquid is better.
ACEA - european standard. In it, everything is almost the same. Only letters others:
- "A" - gasoline;
- "B" - diesel;
- "E" - trucks;
- "C" - universal class (analog "S \\ C")
Instead of a second letter, a digit is specified to decrypt the specification. What it is more - the better. For example, B5-2002 indicates a liquid for lubricating passenger diesel engines, and the specification is adopted in 2002.
So what kind of oil for the winter is best? Naturally, more fluid. Such a liquid will allow to avoid oil starvation during a cold start and will not deliver problems with strong frosts. At the same time, it is worth considering other criteria described in the article. Still from right choice Oil directly depends on the operation of the car.
That's all, leave your comments and read other blog articles.
Extended temperature range of oils 5W30 and 5W40 made them popular among Russian car owners. Why? What benefit will get the engine from this, what kind of oil is better: 5w30 or 5w40 in winter?
Synthetic or semi-synthetic
Currently, there is a tendency to transition to a more advanced viscosity range. The most significant steps in this direction of the chemists have made regarding the creation of synthetics by adding all new components there. For example, the company "Mobile", which is the first who released synthetic lubricant to the market, works with it and experiments already over thirty years. A huge number of competitors that appeared will not be dreamed and spend huge funds to create a new product with advanced features. But developers producing the synthetics of a highly specialized orientation, for example, for highly loaded diesel engines, there are few.
In addition to the "Pyatoche" - synthetics, there is a similar semi-synthetic. Why not use it? Of course, you can use the liquid mineral water, add thickeners there, the synthetic component with modern set Additives - and it turns out a completely standard semi-synthetic winter for example. However, it is known that its parameters in any case will be lower compared to the synthetics. After all, the oil base plays an extremely important role, asking the physico-chemical base.
A well-known analogy is traced with gasoline. There is a technology in which the handicraft in low-octane gasoline A-80 adds multiple additives and obtain AI-98. But, having worked on such a fuel, the motor will soon require the repair: at least it will be necessary to wash the injector and replace the spark plugs. After all, it is quite understandable that the full gasoline of the highest quality will be obtained only by using relevant technologies.
Viscosity
This characteristic has a primary value for lubricating fluid. This parameter determines the limiting temperature of oil use. Therefore, what kind of oil is better: 5W30 or 5W40 (in winter or in summer) is determined by this parameter. If the index is low, the lubricant should not be too viscous to carry out a cold start of the motor starter and pump it over the pump. With high temperature mode, oil, on the contrary, should not have too small viscosity, so that it is possible to provide a permanent necessary level of pressure in the system and the formation of a film that protects against friction around the details.
So, the software are divided into:
Winter. With a small viscosity, the engine will start easily, but the lubricant will not work effectively at high temperature.
Summer. The cold start will be problematic at temperatures below zero degrees, however, with high viscosity, the motor in warm and hot weather will be securely and consistently.
All-season. When it's cold outside, the oil shows the quality of the winter lubricant, and when hot - summer.
All-season acquires are becoming increasingly distributed, ousting the first two species, as now the need to change the oil every time when changing the time of year. At the same time, they show themselves as more efficient and energy-saving. An example of such a lubricant is 5W40 oil (synthetics).
Other features
Of course, other characteristics are important for oil: detergents, anti-wear, anti-corrosion and antioxidative (for this serve as an additive). However, viscosity has one of the main values. Many modern additives increase price. Therefore, you should always pay attention to this parameter and choose the optimal ratio of lubrication properties and future operating conditions of the engine.
The main prescription that should be guided by choosing is the requirements for the manufacturer vehicle. They are given in the manual. Usually they not only contain information about the specific properties that must be inherent in the lubricant used, but also offered specific brands Oils with recommendations to apply them. Often in the manual there is a shell oil (5W40, 5W30 or another type). At the same time, if your car is not new, and you have a little about its operation, you can easily choose a brand for a motor or transmission.
Standard 1999 SAE.
What do these mean mysterious letters SAE? FROM english abbreviation Translated as "Society of Automotive Engineers" (Society of Automobile Engineers). This is an international standard that the viscosity must match. For example, in 1999, the requirements of the standard were as follows.
Oilly determines compliance with a specific season. It is calculated at low speeds from twenty to one hundred degrees and separately with hundred degrees.
Starting properties are revealed through resistance and possibility of obtaining revolutions. Depending on the viscosity and class, are determined at temperatures from ten to thirty-five degrees of frost and high shift speeds (105С-1), that is, the conditions for working in the crankshaft bearings during a cold start.
Pulmonary determines the speed of passing the lubrication to the rubbing details at a cold start, as well as the possible risk of the motor breakage at a cold start due to the grinding of the liners. The indicator is considered at negative temperatures from fifteen to forty degrees and at low shear rates (10c-1). Under these conditions, the lubricant spreads in the pallet to the oil worker when the cold motor starts.
High temperature viscosity reveals real indicator When operating in the warm season, highly loaded motors. Thus, anti-wear characteristics are visible, losses due to friction and influence on the efficiency of the motor. It is fixed at high shear rates (106c-1). Under these conditions, the crankshaft bearings operate at high temperature and load.
SAE classification
Such. sAE Specificationdefining in different conditions. Currently there are six winter classes and five year old. Winter is easy to determine by the presence of the letter W ("Winter", which translated from English means "winter"). The higher the viscosity, the more the numeric index will be.
Winter viscosity is indicated by 0W, 5W, 10W, 15W, 20W. 25W.
Summer - 20, 30, 40, 50.
Consider on the example of 5W40 oil.
The characteristics are as follows. Class - viscosity 5W. As it is clear, it can be used in winterThat is, it is from this indicator that the motor in the cold will be revealed. Thus, in order to understand which oil to fill in the winter, you need to pay attention to this indicator.
The number "40" reveals summer performance, that is, the possibility of engine functioning at high temperatures.
If, as in our example, there is a designation and one, and other classes (that is, the engine oil 5W40, as well as 5W30), this indicates the all-season nature of its use.
How to choose a winter class
Choosing viscosity, first of all are guided by the instructions of the car manufacturer. If there are no such, follow general recommendations.
Picking best oil For winter, you need to consider the conditions under which the vehicle will be operated.
Then problems with the launch of winter and negative consequences for the motor (for example, fast wear and jamming during start-up, which can happen in oil starvation conditions) will be avoided regardless of whether it is filled with 5W30 or 5W40 for the winter. It is necessary to understand that when the motor is launched, even if it does not occur at a strong frost, and with a plus mark on a thermometer, it is necessary to pump the oil pump on the lubricant system so that the liquid gets into all the rubbing parts and the channels. Until this time, the motor works in conditions of lack of oil. Therefore, friction and wear are significantly enhanced. The greater the lubricant can maintain fluidity in low-temperature mode, the better the protection for the motor will be ensured.
How to choose all-season
Winter properties are reflected from the left side, and the summer - right. Thus, wondering what oil is better - 5W30 or 5W40 - in winter, it is necessary to pay attention only to the indicator on the left, and in this case the same one.
Therefore, you should pay attention to the difference in summertime and select suitable option Depending on the operating conditions of the vehicle.
Viscosity properties
This indicator depends on ensuring the engine launch without heating, free pumping of oil on the system and, as a result, stable lubrication of all driving parts at the highest possible loads and ambient temperature.
Even in a temperate climate, the change in the winter temperature to the largest warm-up is up to a hundred ninety degrees. Therefore, seasonal oils must be changed depending on the time of year. However, when all-season appears (it applies to them, for example, the engine oil 5W40I 5W30) the problem was removed. Thanks to its additives, they are able to show the necessary properties at different temperatures. That is, with a negative meaning, they are similar to winter oils, and with high positive - summer.
Additive
Additives do not significantly increase viscosity at low temperatures, but are greatly raised - with high, when the number of macropolymer molecules is significantly increased. In all-season (to which 5W30 lubricant and 5w40 oil) are characteristics of the time ability to change their viscosity, also relative to the shift rate. With a reduction in speed, it increases, and with an increase - falls.
Most of all, this property is manifested at low temperatures, but at high preserves, which has good consequences for the engine: low viscosity during the cold engine facilitates the descent, and when he is heated - the loss of energy is reduced due to friction, which saves fuel.
Low temperature
The low-temperature characteristic of the oil is opened through the frost temperature when the lubricant ceases to flow. This indicator is realized when the temperature is five to seven degrees below the one at which the fluidity was possible.
Most often, the frost occurs due to the formation in the cooled lubricant of paraffins.
What kind of oil is better: 5w30 or 5w40 (winter)
Based on the foregoing, it is clear that in the cold season, both species show themselves the same. Therefore, for the winter is perfectly suitable and one, and another type of lubricating fluid.
In this article, we compare motor oils 5W30 and 10W40, we will analyze each of them, we learn their properties, areas of application, talk about their advantages and disadvantages in front of each other. And find out what to choose and in what way to give preference to one or another lubricant substance.
Criterias of choice
Everyone knows that motor oil besides its main task, lubricate the engine parts, minimize its wear, have a number of other functions. Additives that are added to the oil are capable of preventing oxidation, corrosion, purified from particulate sediments and shallow shavings.
Everyone makes his choice, pushing out what goals pursues and what wants to get from the engine oil and from the car as a whole.
Factors to consider when choosing:
- Style ride.
- Temperature regime - for different regions, we need different viscosity.
- Mileage. IN new engine Pouring less viscous oil, in the engine with mileage - more thick.
- Tolerances
- Recommendations for a specific car.
Classification and decoding
Automas are systematized according to two main features:
- Scope of application - API classification.
- Oil viscosity - SAE classification.
API systematization divides oils in 3 categories:
- S -Benzine aggregates;
- C - diesel units;
- EC is a universal protective lubricating liquid.
SAE 5W30 oil is a standard look of oil suitable for all seasons. The figure 5 in front of the letter "w" suggests that the oil is suitable for use at a temperature of -30 ºС "Winter". The digit after "W" says the positive "summer" indicator +25 ºС.
SAE 10W40 oil is one of the most common, as it is all-season and provides confident and reliable engine operation in a wide temperature range. Based on the labeling, in the winter period, up to -20 ºС, in the summer is not higher than 35 ºС.
What is the differeble 5W30 and 10W40
Both lubricants are universal and satisfy the requirements of most users. Having considered their characteristics, dealing with marking and classifiers, you can make conclusions and conclusions.
The difference between 5W30 and 10W40:
- Temperature Range. Not a much significant difference, at temperatures from -25 ºС to +25 ºС, properties will be identical. But for some regions, it is necessary to use 5W30 in winter - less thick, and in summer 10W40 is more liquid.
- An important difference: 5W30 - synthetics, 10w40 - semi-synthetic.
- Price: 5W30 more expensive, 10w40 is cheaper.
What to choose?
Owning all the above information, the choice remains only for you. The main thing is to ensure the smooth start of the engine, which will increase its resource.
We will summarize when and which viscosity to choose:
- Big Mileage - 10W40, New Engine - 5W30.
- For northern regions, low temperatures in winter - 5W30, for southern hot summer - 10W40.
- For domestic cars You can use semi-synthetic 10W40, for foreign cars it is desirable synthetic.
- Operating conditions. The larger the load on the engine, the fat need a mixture.
Before choosing an oil, check the car's instruction, in the overwhelming majority you need to use exactly the one that the manufacturer recommends.
Pay attention to the manufacturer tolerances. Engineers who design the engine are calculated on a certain viscosity of the oil. The fact is that the viscosity of the oil variable. At engine temperatures 50, 100, 150 ºС - the viscosity of the oil will be different. When you are consciously using a more thick mixture - an overheating of the cylinder-piston group is ensured. If a mixture of fat, which is provided - you can get a "wedge" engine.
Therefore, the tolerances for each car were invented, which should not be neglected, especially if you are the owner of an expensive foreign car.
Is it possible to mix 5W30 and 10W40
Despite the fact that both products have quite a lot in common in their characteristics, mix them forbidden. Do not forget that 10W40 semi-synthetic oil, and 5W30 synthetic. Having various bases and packages of additives, they may unpredictably affect each other, and lead to deposits! Replacing and topping the oil is allowed only one base, one manufacturer.
In the case of transition from 5W30 to 10W40, and on the contrary - be sure to flush the engine.
Perform the washing of the engine as prevention - not recommended.

Vissedy additives of Unol TV # 2 motor oils (1 per)
Motor oils can differ very much in their characteristics - their parameters depend on the method of production, use, as well as the chemical composition of the main raw materials.
One of of the most important characteristics Lubricants are the ability to work in various climatic conditions. In our country, frost resistance is much more important, since in some of its regions most of the year the negative ambient temperature is maintained.
Choose the best engine oil for the engine will not be easy, since a lot of manufacturers are represented on the market, which offer their products with unique properties. However, our rating will help you to take the right decision that will allow to extend the time of the smooth operation of the car.
Synthetic compounds
Best oils for modern cars Synthetic mixtures are considered. Them distinctive feature It is adding a huge amount of artificial additives that remove accumulated deposits, protect the metal from destruction, the sulfur oxides associate and perform other functions.
Synthetic engine oils have a high fluidity, due to which they create minimal resistance and significantly reduce the friction of moving parts. However, this feature does not allow to use them in older or strong worn engines - For example, they are not suitable for VAZ of classical models.
Universal option
Numerous studies show that the best is Shell Helix Ultra.corresponding to 5W40 classification. Certificates issued by Bentley, Ferrari and Lamborghini companies are talking about his quality - they allow you to use this oil in their engines during operation in a cold climate.
Shell Helix. Ultra 5W-40 for gasoline engines
The main advantage of such engine oil is to preserve the unchanged consistency even at a temperature of -40 degrees. Due to this, a confident start is provided under any circumstances, the load on the starter and the car battery decreases, and the rate of wear of the movable compounds is reduced 5 times 5 times with a negative air temperature.
If you are looking for a winter diesel oil, You can choose Shell, without even considering other options. It is adapted to operation on any fuel, including diesel, compressed and, and also provides effective lubricant Turboculant systems.
Shell Helix Diesel Ultra 5W40 for diesel engines
Will not be a problem and operation in modern engines With the recycling of exhaust gases or other fixtures - oil ensures the purity of the exhaust corresponding to the Euro-6 standard. Its most important advantage can also be called excellent detergents - when using this oil, the amount of deposits decreases 2-20 times compared with the compositions of competitors.
Maximum resource
The second place confidently occupies the British Castrol EDGE oil, corresponding to the same viscosity standard as the products created by the Dutch. It is worth remembering that the company Castrol is a division of the international concern British Petroleum that invests huge funds into the development of innovative petroleum products.
The result of their research was the oil that forms a viscous protective film in the regions increased frictionHowever, it remains liquid in all other parts of the lubrication system. Due to this, the engine wear is reduced in all climatic zones and at any level of load. Experts say that the minimum increase in the resource on engines Volkswagen. When using this lubricant is 10%.
If you doubt what winter oil is better to pour into the engine, you definitely choose Castrol. For use in cars and easy commercial vehicles, as well as in diesel, gasoline and gas motors.
In addition, such oil was certified and domestic manufacturersThat will be a good news for car owners VAZ. The only substantial minus of such a lubricant is bad compatibility with high-breeding - owners of sports car better consult with a mechanic before purchasing oil Castrol.. In addition, the creation of an anti-wear film requires greater viscosity than Shell that hesitantly worsens the cold start of the motor.
For our roads
If you are looking for lubricant For a car that will be operated not in the most best conditions, It is worth a preference to Zic XQ Ls. Such oil is capable of working in conditions of high sulfur, phosphorus and iron in fuel, which is typical of Russian refills removed from major cities.
Due to this, it is possible to significantly reduce the number of deposits in different parts of the engine, as well as to improve the ecological exhaust class. The advantage of such engine oil is both resistance to low temperatures - like Shell, it does not change the consistency even with the strongest frosts.
The oil is excellent for diesel engines, since it reduces the level of hydrophope ash, increasing the reliability of the vehicle. It can also be used in high-affected engines with a high degree of compression, since the lubricant has a multiple stamina supply.

The only drawback can be called a fairly high price and a small product prevalence. japanese brand in Russia. In addition, the manufacturer recommends using it only with original oil filtersTo avoid reducing the performance of the lubrication system.
Semi-synthetic
The marking of winter oil in the level of viscosity 10W40 is likely to mean that you are semi-synthetic lubricant, which is much cheaper than pure synthetic compositions.
In its chemical composition, there are a lot of natural components that are obtained from crude oil, but artificial additives performing various functions are also present in this product. Semi-synthetic oils have an increased viscosity, so they are recommended to be used in the following cases:
- In old cars with a small capacity of the pump system of lubrication;
- In worn engines with a large amount of cavity cavities clogged with combustion products;
- IN commercial machinerydesigned for an increased resource of operation;
- In low-rod diesels.
Thanks to this, semi-synthetic oils are considerably popular in Russia and the CIS countries, where the average age of the fleet is quite large.
Minimal wear
Optimal option For foreign cars with is a semi-synthetic mobil oil Ultra. Such a brand of winter oil is characterized by the ability to significantly reduce friction even at very low ambient air temperatures.
Due to this, it is possible to minimize wear and significantly increase the engine resource. In addition, with a sharp decrease in temperature - by 20 degrees per day and more, such oil manifests itself as it is impossible, substantially facilitating the cold start of the motor. Thanks to this, it is recommended to be used even in the complex climatic conditions of the north of our country.
The advantage of the oil can be called relatively low cost for the products of the foreign brand. In addition, the certification of this lubricant was performed by domestic manufacturers, which makes it possible to use it in the injection engines of VAZ or gas.
The only minus is some loss of properties with long-term influence of low temperatures. If your car spends the winter in the open sky, immediately after heat offensions, the oil is recommended to change. This will significantly reduce the level of wear and achieve an increase in motor resource by 5-10%.
Domestic innovation
A good option for all-season operation is russian oil Lukoil Suite - It allows the motor to work with a small wear at any temperatures. Lubricant preserves almost unchanged consistency with severe frost and terrible summer heat.
However, it is still not designed for a long effect of abnormal temperatures, so after two weeks of frosts under -40 degrees, it is not necessary to expect a very easy motor launch. But in such a semi-synthetic oil added a huge number of protective and detergent additives. If it is poured into a new engine, it will be possible to prevent the accumulation of combustion and angry products, as well as protect the power unit from the destruction of the metal, the formation of cavities and microcracks.
The oil is recommended by many well-known manufacturers - in particular, it is the only one in Russia, which received the Certification of BMW, Mercedes and Audi at the same time. It can be used in diesel or gas engines without prejudice to them, as well as in petrol aggregates With turbocharged, gases recirculation system and direct injection.
Oil shows excellent results when operating in light commercial machinery with increased level Loads. In addition to moderate temperature resistance, its minus can be called high cost for domestic products.
Potential leader
If you ask what winter oil is better among semi-synthetic, then you can again recommend Shell, but now choose the composition called HX7. It is ideal for modern vehicles due to the presence of a large amount of detergent additives and substances neutralizing sulfur oxides. In addition, moderate viscosity can significantly reduce friction, increasing the resource power aggregate. In winter, the consistency of such a product varies very slightly, which contributes to the relief of the cold launch.
Shell Helix HX7 - leader among oils
That modern butter For 4-stroke engines could be the leader of the rating, if it were not for one interesting circumstance. This lubricant is made on four plants located in France, USA, Russia and China.
At the same time, only the first two options fully correspond to the properties described above, and we are almost impossible to buy oil from the USA. Products from Russia and China are ahead of many oils of competing brands, but significantly inferior to the original shell from France. Therefore, oil is recommended to buy in large service centers and stores or order it via the Internet, having received a guarantee that the French product will be provided to you.
Selecting the oil for winter, be sure to consider it should have a low viscosity - the first figure in the marking should not exceed 10. Bay mineral oilYou risk discovering that your car will not start frosty in the morning without additional engine warming up. The optimal option will be the so-called arctic compositions that thicken only at temperatures below -50 degrees.
They can be found as among synthetic oilsand in the semi-synthetic group. In addition, it is better to use the products of famous brands - Shell, Mobil, BP, Liqui Moly.Because these manufacturers laid a lot of money in the development of perfect oil.
