This question is asked, perhaps, by every car owner in the world. In fact, this problem can be solved simply: just open the car’s operating manual.
However, specialized literature does not always contain the answer to the question: which oil is best to pour into the engine.
Most automakers produce engines that can use any type of oil for normal operation - synthetic, mineral or semi-synthetic.
Synthetic, semi-synthetic or mineral?
You can determine which engine oil to pour into the engine by calculating the costs that will be incurred for its periodic replacement.
Any, even the best lubricant, is evaluated according to two main criteria:
- Costs for the end user;
- Operational characteristics.
Depending on the method and technology for producing motor oil, its performance characteristics also change. It is worth noting that the production technology of synthetic and mineral types is practically the same.
The basis of any oil is a base component, which is mixed with certain additives that give the finished product certain performance characteristics:
- antioxidant;
- anti-corrosion;
- anti-wear;
- detergents and others.
In order to lower the pour point of mineral oil, a limited number of depressant additives are used during the production process, the use of which makes it possible to obtain a motor mineral product of class 10W- and lower.
Such additives make it possible to maintain the standard parameters of this indicator for mineral oils within 10W-30, 15W-40 and 10W-40. The use of synthetic additives in the base makes it possible to obtain lubricants with a viscosity of 0W-, 5W-, thanks to which it becomes possible to start the engine at low temperatures and provides immediate lubrication from the first moments of operation.
However, the most important advantage of a synthetic base compared to a mineral one is its high thermal-oxidative stability. Simply put, while the engine is running, synthetics deteriorate significantly less than its mineral counterpart.
However, in the case of the mineral type, this problem is solved by adding some antioxidant additives. But there is one drawback: the addition of such additives sharply increases the amount of soot and varnish deposits that settle on engine parts and components during operation. Long-term use of such a product may lead to replacement of the piston rings.
Which engine oil is best to use in winter?
Low air temperatures in winter make starting a car engine much more difficult. To simplify the starting process and save the driver’s nerve cells, you need to know what oil to pour into the engine in winter.
When choosing which oil to pour into the engine in winter, you should first look at the technical documentation of the car.
As a rule, such papers indicate which motor fluid (brand, characteristics) should be poured into the car in winter.
If it is impossible to obtain information from such documentation, then a good lubricant is selected according to certain tolerances and parameters. If this is not possible (the specified characteristics are outdated), you will have to rely only on the automotive chemical market and the knowledge of the driver.
What kind of oil to pour into the engine is a purely personal decision of each car owner, and rave reviews from friends and the words of sellers are not helpful in this matter: that fabulous material that suits another car may turn out to be poison for yours.
It is worth determining which engine oil was previously poured into the engine. The quality of a lubricant is determined by its characteristics and effect on the engine.
If the car was purchased secondhand, then all the necessary information will be obtained from the previous owner. In the absence of information, you will have to flush the engine - a costly procedure, which, however, guarantees an increase in the life of the car.
Selecting motor oil by viscosity index
When choosing which oil to pour into the engine, you should pay attention to the viscosity of lubricants, which is one of the main indicators of such liquids.
While the engine is running, its components and assemblies rub against each other at high speed. An oil film must be present between the contacting elements: it reduces friction, heating and wear of parts and ensures the tightness of the connection during movement.
Incorrectly selected engine oil can negatively affect engine performance: for example, a high-viscosity lubricant in the winter will cause additional friction and resistance, which will reduce engine performance. Reduced viscosity will lead to rapid wear of engine parts.
The best option would be automobile oil, which in winter will ensure easy engine starting and, at high operating temperatures, create the necessary protective film.
Types of motor oil by chemical composition
For a long time, only mineral oil was poured into car engines. Accordingly, the question of what oil to pour into the engine was not so relevant.
This lubricant is created on the basis of natural raw materials, that is, oil. However, it has one drawback - it is not suitable for use in the cold season, especially at temperatures below -10° Celsius - it freezes in the engine.
Mineral motor oil has been replaced by synthetic motor oil, created through the synthesis of molecules, which ensures the same performance regardless of operating temperature.
There is another type of machine lubricant - semi-synthetic, which is a cross between synthetic and mineral analogues and is a natural base to which artificial additives are added.
Each type of motor oil has its own disadvantages and advantages. For example, mineral oil cannot be used at low temperatures, but it helps clean the engine from sediment and fumes that are removed along with the used lubricant during replacement.
Semi-synthetics are more resistant to temperature changes, but they are not suitable for harsh winters: the low temperature threshold of such a lubricant is too high.
Synthetic motor oil is considered the most popular due to its resistance to low temperatures and maintaining performance characteristics regardless of engine temperature.
However, when using high-quality synthetics, there is one caveat: if a bad product was previously poured into the engine, then a sudden switch to a high-quality lubricant can cause the peeling off of all the sediment and carbon accumulated in the engine, which will lead to clogging of the filter and oil channels and subsequent expensive car repairs.
It is necessary to determine which oil to pour into the engine before changing lubricants. The best option is to flush the entire system with cleaning fluid and only then fill in a new one. In the future, it is recommended to change it strictly according to the schedule established by the manufacturer.
Types of motor oil according to SAE
The classification of engine oil viscosity level used throughout the world was created by the American Society of Automotive Engineers:
- Winter
A few years earlier, many car owners, when asked which oil is best to fill in for the winter, answered - winter. According to the SAE classification, its designation was the letter W. The packaging of such a lubricant usually indicated SAE 5W, 10W, 15W, etc.
The number located in front of the letter W indicated the minimum temperature the engine oil could withstand without harming the engine. In the winter season, such a product did not become viscous, but when the temperature of the working environment increased, it quickly became liquid.
- Summer
This type of motor oil, according to the SAE classification, is indicated only by a number. Actually, the number means the highest temperature at which the lubricant can be used.
- All-season
Over the past few years, all-season motor oil has become very widespread, displacing winter and summer analogues from the markets. It has certain advantages: it does not need to be changed before each season, it is easier to use.
The designation of this type of lubricant is the letter W and two numbers located on either side of it. The first means winter indicators, the second - summer. Of course, all-season oil also has its own temperature thresholds, but choosing the right option is much easier.
Types of motor lubricant according to API
When choosing motor oil for the winter, they rely on the classification of lubricants created by the American Fuels Institute. This system takes into account the quality of engine oil.
There are two main designations in the API classification: S indicates which product is suitable for gasoline engines, C indicates which oil to pour into a diesel engine. You can often encounter a double designation indicated on the lubricant packaging, which allows the use of oil in both types of cars.
Normal oil pressure in a car engine
One of the most common questions along with choosing engine oil is determining its pressure level in the engine.
As a rule, many modern car models do not have special devices that display pressure data on the dashboard - only an emergency warning signal is provided in the form of a light bulb.
It is almost impossible to independently monitor pressure changes without directly checking the engine.
Choosing a high-quality lubricant is not the whole process of preparing a car for the new season. It is important to know what oil pressure should be in the engine in order to ensure its smooth operation. This indicator largely depends on the engine itself: the number of horsepower, cylinders and valves, and the type of fuel used.
For idle speed, the average norm is about 2 bar, for high speed – from 4.5 to 6.5 bar. However, such information is included in each operating manual and technical documentation for the car.
Where to replace
If the car has a diesel engine, then the engine oil must be of the highest quality. It is advisable to fill it at proven service stations that have a quality guarantee.
Replacement timing
It is impossible to name specific terms for changing engine oil - this indicator is purely individual for each car. Considering standard operating conditions, it is advisable to change the lubricant in the power unit every 7-10 thousand kilometers.
If the car is operated in difficult conditions, then it is advisable to reduce the interval between lubricant changes. For cars with diesel engines, the change must be carried out every five to six thousand kilometers. Along with the engine oil, the oil filter is also changed.
Flushing the engine when changing lubricants
Changing lubricants may require a complete flushing of the vehicle's oil system.
As a rule, such cleaning of the power unit is carried out if the oil is changed for the first time or it is unknown what specific product was used before; if the brand of lubricant changes, its viscosity or the car engine is very dirty.
As for other cases, many experts say that there is no need to do it. Japanese professionals, for example, advise flushing every 40 thousand kilometers.
The main disadvantage of flushing agents is that during their action they settle on the components and parts of the car. Since their composition often includes caustic substances, thanks to which all contaminants are corroded, when new oil is added, they are mixed with it, significantly reducing its performance characteristics. As a result, such a decrease in the quality of the lubricant can adversely affect the condition of the engine and lead to its repair - in the worst case.
What engines does AvtoVAZ install on the Priora?
- VAZ-21114 (1.6 l., 8 cl., 81 hp.)
- VAZ-21116 (1.6 l., 8 cl., 90 hp.)
- VAZ-21126 (1.6l., 16kl., 98 hp.)
- VAZ-21127 (1.6 l., 16 cl., 106 hp.)
- VAZ-21128 (1.8 l., 16 cl., 120 hp.)
How much oil is in a Priora engine? When changing the oil, it is recommended to fill 3.2–3.4 liters through the neck. new oil. After running the engine for several minutes, check the oil level and, if necessary, add it so that the mark on the dipstick is between the “MIN” and “MAX” levels.
What kind of oil should I put in Priora? We recommend that you adhere to the manufacturer's recommendations: the engine lubrication system should be filled with oil for gasoline engines that corresponds to group SJ or SL according to the API classification (B5/DZ according to the AAI classification or AZ/VZ according to the ACEA classification). Select oil viscosity according to SAE in accordance with climatic conditions.
Table No. 1: 
Table No. 2: 
What kind of oil is in the Priora from the factory? Lukoil, semi-synthetic.
About oil consumption in the Priora engine. Consumption of a certain amount of engine oil (up to 1 liter per 1000 km) during normal engine operation is normal. The amount of consumption depends on the viscosity of the oil, the quality of the oil and the operating conditions of the vehicle. For example, driving at high speeds and accelerating frequently consumes more oil. It is also worth considering that a new engine consumes more oil, since its pistons, piston rings and cylinder walls have not yet been ground in.
How to buy original high-quality motor oil? When choosing motor oil, you should understand that there is a large percentage of counterfeits on the market. To buy original, high-quality motor oil, it is recommended to contact trusted stores, rely on reviews, or order engine oil online directly from the manufacturer. What do you think is the best oil for Priora?
IMPORTANT! The survey is about engine oil: VAZ-21114 (1.6l, 8cl., 81 hp), VAZ-21116 (1.6l, 8cl., 90 hp), VAZ-21126 (1.6l., 16kl., 98 hp), VAZ-21127 (1.6l., 16kl., 106 hp) and VAZ-21128 (1.8l., 16kl., 120 l. With.).
Quite often, motorists cannot decide which oil is best to pour into the engine. Today the choice is more than varied, but it’s worth starting with the type of product. There are mineral, synthetic and semi-synthetic oils.
Many will say that this is a matter of taste, and any lubricant will do, the only difference being that a synthetic one will last you longer than a mineral one, but it still has its own characteristics. Below is a guide to choosing oil.
- To know exactly which oil is best to pour into the engine, the first thing to consider is the car manufacturer’s recommendations. Who better than the engineers of your car brand to know which lubricant will ensure a long service life of the car?
- In addition to general recommendations, the manufacturer often leaves comments regarding winter and summer lubricants. However, the manufacturer does not always indicate a specific brand, often leaving his wishes at the level of viscosity of the lubricant. Thus, it is up to the car enthusiast to decide whether to choose synthetics or a mineral product.
- What you should pay attention to when deciding what kind of oil to pour into the engine is the wear and tear of your car and, accordingly, its engine. As an example, we can consider the case where mineral oil products were used for a long time. As a result, cracks have formed in the rubber seals, which are gradually filled with lubricant deposits. When changing the oil to synthetic, these cracks will be washed out, which will lead to the necessary replacement of the oil seals and seal.
This naturally suggests that mineral oil is better suited for older cars, which will help avoid premature repairs of your car. But here it should be remembered that such lubricant will have to be changed more often.
If your car is new and high-revving, then a synthetic product will be the best choice.
Choosing a diesel lubricant
Now let's talk about what kind of oil to pour into a diesel engine.
- Most motorists in this case prefer semi-synthetics. At its core, such a lubricant is a mineral oil product that has undergone chemical treatment. The main advantage of such a product is its low cost compared to synthetics, as well as an increase in service life, unlike mineral products.
- For a diesel engine, the manufacturer’s advice plays an important role, as well as engine wear and operating modes.
- Another interesting detail is the fact that the conditions and roads on which our cars drive have long been recognized as difficult, so changing the lubricant twice as often as required by the regulations will definitely not make things worse.
- For owners of turbocharged diesel engines, in addition to what kind of oil to pour into the engine, the role of the frequency of changing the lubricant is important, which usually becomes even less.
Also find out where and about.
In any case, it is necessary to change lubricants at least no less often than required by the manufacturer. Don't forget about the quality of the lubricant.
Classification of lubricants
After determining which oil is best to fill, as well as considering the types of oils, it is time to move on to their classification. 
SAE classification (viscosity) - this standard is international and is designed to determine the viscosity level of a liquid. Most likely, the manufacturer’s recommendation will be in this classification.
Based on viscosity, lubricants are divided into:
- summer;
- winter;
- all-season.
Winter types of oils are often marked W on the packaging and a certain numerical index. For example, we give models with the designation 10W, 15W, 25W. At the same time, the numerical index shows what negative temperatures it is designed for.
There is a rule to determine what temperatures a product can support. Its essence lies in the fact that 35 must be subtracted from the number in front of W, obtaining a negative value, which will be the minimum temperature of this model of lubricants. For example, 10w means that it can be used at temperatures down to -20 degrees. However, not everything is so simple, and this formula only works for mineral oils.
All-season oils are labeled using not only winter parameters, but also summer ones, and look like this: SAE 10W-40. The number “40” in this marking is borrowed from summer varieties of engine oils. Simply put, this numerical index is designed to help decide which oil is best to pour into the engine in the summer.
Choosing the best brands
Now let's move on to practical advice and a little analysis of the market today. For convenience, we will describe the advantages and disadvantages of oils recommended for each season.
What oil is best to put into the engine for the winter? These are Shell Helix Ultra Synthetic 5W-40 or Motul 8100 X-clean 5W40, as well as Bardahl Xtec 5W30 C3. They differ from each other in price and slightly in quality. Why insignificant? The fact is that of these three, Shell is the cheapest. It is inferior to Motul and Bardahl, but is also capable of protecting your engine from wear. The main thing is to change this lubricant on time, then everything will be fine. 
The first option costs about 2 thousand rubles, the second - 4000, and the third - 3300 rubles. Prices may change, since economic conditions in the country are not the best, you understand.
Advantages of the listed brands:
- up to five times more effective when compared with a mineral product;
- promotes easy starting of the car in the cold;
- saves fuel;
- This brand is used by famous automakers such as Ferrari.
The disadvantage is the high cost.
We choose a lubricant for the summer - LIQUI MOLY MoS2 Leichtlauf 15W-40. The advantages are:
- engine wear protection;
- excellent performance over a wide range of temperatures;
- acceptable cost.
The disadvantage is that it cannot be mixed with products from other brands.
What brand of oil is best to fill in during the off-season - Mobil 1 5W-50. Among the advantages we highlight:
- frost resistance;
- high quality;
- versatility;
- Suitable for turbocharged diesel engines.
The disadvantage is the high cost.
How often should it be replaced?
Now is the time to find out at what mileage it is necessary to change the engine oil. First, let's decide what type of lubricants we have chosen for ourselves. After all, for each type the service life is different. 
- Let's start with mineral lubricant: it is replaced most often, since it is based on petroleum products that cannot be “cleaned”. The recommended replacement period from the manufacturer is once every 8-10 thousand mileage. I recommend changing every 5 thousand
- Semi-synthetic lubricant boasts, as already mentioned, chemical treatment, which increases its service life to 10-15 thousand mileage. If you often delay up to 10 - 15,000 km. mileage, then engine wear increases. It’s best after 5000, the red zone is 7000.
- Naturally, the record holder for durability is synthetic oil, which can not be changed for 20 thousand kilometers - as many manufacturers assure. It is more expensive than those presented above, however, I also recommend changing it every 5-7000 km. The red zone is 10,000.
Please note that the data is given for gasoline engines. For diesel engines the situation will be somewhat different. On average, it will have to be changed twice as often, and even when using synthetic, replacement will occur after only 10 thousand kilometers. This is due to the different structure of these units.
Now it will not be superfluous to know what the volume of oil in the engine is. Here everything is also different, and you will have to divide the engines by size.
- For a Russian-made passenger car, the volume of lubricant will be from 1.8 to 2.4 liters. However, there is an exception everywhere, and it should be understood that the larger the volume of the power unit, the more lubricant will be required.
- For foreign passenger cars with engines ranging from 1.8 to 2.4 liters, a little more than four liters of lubricant will be required. Moreover, what’s convenient is that you don’t need to buy a 5-liter canister, since you won’t be able to drain 100% of the used oil, so 4 liters is most often enough. Also, do not forget that when changing the oil, you will need to change the oil filter.
- If we talk about cars more seriously, then as an example we can cite the Niva, where the volume already reaches 3.75 liters. A Gazelle or Volga can hold up to 6 liters of lubricant.
Causes of oil product wear
For each car, it is very important what oil consumption is in the engine. So, for a new engine, without obvious signs of wear, it is considered normal to consume about 100 grams of oil per 1000 kilometers due to loads, aggressive driving or other circumstances. However, this figure may be higher for a car with high mileage. In conclusion, let’s look at what can affect the wear rate of oil products in the engine. 
- Oil filter. This is a kind of first line of defense for the higher lubrication system, which traps solids and prevents them from re-entering the system. If the filter is of poor quality, the oil product may lose its properties much faster, which will increase engine wear. Therefore, it is worth making it a rule to buy a good filter for good oil.
- Forced crankcase ventilation. Serves to remove excess gases and moisture from the system.
- Severe vehicle operation conditions.
Since everyone has their own idea of “heavy” operating modes, let us clarify this issue. These include:
- trips over short distances, shorter than 4 kilometers;
- travel up to 10 kilometers at an ambient temperature of about zero degrees;
- long trips at high speeds, especially in hot weather;
- engine downtime at idle or at low speeds (meaning traffic jams);
- towing other vehicles, as well as frequent driving while loaded;
- driving in dusty areas.
It is always important for car enthusiasts to know which brand of oil is best for their car. The oil prevents contamination and jamming of engine systems and prevents wear on the working unit, but if you choose the wrong lubricant for your car, the driver risks being left without wheels for a long time.
After all, using the wrong oil is fraught with frequent repairs and major breakdowns, which can lead to the “loss” of the entire engine system as a whole. Of course, you can always replace broken parts, but why make them break?
There are a number of features that affect which oil to pour into the engine for each specific car. This is both the type of vehicle (truck, family or sports car) and the type of fuel used, because one brand is better for diesel engines, and other lubricants will be better for gasoline engines.
The brand of oil that is best suited for a car engine depends on the conditions for which it is used. Some brands are designed for the dirtiest engines, with a large number of impurities in the fuel, sulfur residues and other features. These types of oil are more suitable for diesel engines.
For gasoline engines, which often use fuel whose quality is much higher, others designed for cleaner operating conditions are also suitable.
In winter and summer heat, the choice of oil may also differ - the presence of condensation or the start, warm-up and operating temperatures of each engine may differ. It also depends on the fuel used and, accordingly, the engine efficiency factor, which affects the combustion temperatures of the fuel.
In general, there are quite a few possible characteristics of an oil that affect its range of application.
Frequency of oil changes, depending on the conditions of its use
Experienced drivers know that not only the brand of oil determines the quality of car maintenance. The longevity of a vehicle engine is also affected by the frequency of its replacement.
There are many recommendations given by oil and vehicle manufacturers regarding the frequency of oil changes. This usually depends on the operating conditions of the car - the more severe these conditions, the more often it is worth completely draining and replacing the oil, adding it to the system or performing other manipulations, including the use of special individual additives.
A domestic passenger car under operating conditions typical of Russia will require, on average, a complete oil change every 10 thousand kilometers.
But under more severe conditions (extreme temperatures, prolonged loads), an oil change will be justified in areas of 7-8 or even 5 thousand kilometers.
Foreign-made cars with souped-up engines may require even more frequent oil changes, but they can also use branded oils designed for the appropriate conditions of use.
Which oil base is better - synthetic, semi-synthetic or mineral?
The choice of brand is also influenced by its basis. In addition to the base, various additives are also added to the oil, but the impurities do not affect its basic lubricating characteristics as much as the base.
Miniralka
It is known that the mineral base- cheaper to produce, but differs in that it has a lot of mineral residues and their large fractions make the oil not so homogeneous. Thanks to this, the oil becomes more economical, but, unfortunately, it pollutes the engine much more and leaves a lot of residues.
Synthetics
Synthetic bases created using special synthesis. This allows you to obtain high quality oil - homogeneous, without potentially harmful impurities. This makes synthetic oil more expensive, but at the same time the quality of work from its use increases significantly.
Semi-synthetics
Semi-synthetics- the optimal option for car enthusiasts who are willing to pay a little more for lubrication, but do not require the highest quality oil. Their price, of course, is significantly higher than that of mineral oils, but lower than that of synthetics. In addition, in terms of quality characteristics, it is almost not inferior to synthetic brands. Having decided to change the type of oil used, some drivers resort to semi-synthetic oils in order to gradually switch to another lubricant, which makes it also quite popular. This also applies to experimental transitions - after semi-synthetics it is much easier to return to the previous oil.
It is worth considering that global manufacturers of motor oils and the imported auto industry recommend synthetic types of oil - they best preserve the engine and allow you to use its resource much longer.
How to choose the best brand of oil for gasoline and diesel engines?
Since diesel fuel is much “dirtier”, diesel engines require oils that have much more dispersing, cleaning and antioxidant additives.
Dispersing impurities hold solids that appear during engine operation and oil burnout - soot particles. Cleaners should prevent the appearance of carbon deposits. Due to excess sulfur, diesel fuel is subject to more intense oxidation, so the presence of more antioxidants is justified.
For gasoline engines, in turn, such a number of additives is not necessary. A large number of additives makes the oil less homogeneous, which most often manifests itself at extreme operating temperatures. Therefore, the service life of motor oils for gasoline engines is quite wider than that of diesel engines.
The choice of oil is important
The correct choice of oil brand will allow the motorist to get the longest and highest quality effect. But for this it is worth spending some time to decide on the brand.
When operating a vehicle, any car owner periodically faces the question of what brand of oil is best to pour into the engine. Of course, before selecting it in a store, you need to study as much information as possible about it: read all kinds of instructions, which detail specific recommendations, listen to the opinions of experts, as well as reviews from car owners. If you purchased a used car without a service book, then official dealers or spare parts suppliers will be able to provide useful information about it.
In this case, the wear of the motor must be taken into account. After all, when using mineral water, if cracks appeared, for example, in a pan, then they were gradually filled with deposits. After pouring synthetics, you will wash everything, including hardened deposits. As a result, the leak may reappear. And if you also use a 15-minute flush, the engine can be completely ruined. Therefore, it is advisable to carry out separate cleaning of engine elements or at least manually clean the pan.
What to do and what brand is better to fill in the engine? Let's consider what needs to be taken into account when choosing a fluid in general and for individual cars in particular.
Selecting the best oil
When choosing the best lubricant for their car, car enthusiasts begin their search with a list of existing fluids by rating.
Then the car model, mileage, age and its general condition are taken into account. Also, to make the right choice, you need to know the differences between synthetic and semi-synthetic types (mineral water is used only on old cars, so we will not cover it in detail).
Synthetic oil is completely artificial. It is obtained by processing oil or gas through complex molecular synthesis. This mixture does not lose its properties under the influence of various factors, even as a result of long-term use.
Semi-synthetics are obtained by mixing mineral and synthetic types of lubricating fluids. Mineral water is considered a natural product, as it is the result of the distillation and purification of oil.
Synthetics are able to penetrate much better and also have greater fluidity. Thanks to its use, fuel consumption is reduced and power loss due to friction is reduced. Its beneficial properties last longer. At the same time, the engine wears out less, and oil changes are needed less frequently than when filling with semi-synthetics. This type of liquid is less affected by overheating and decreasing temperature.
For an old car that has insufficient technical documentation, specialists select the appropriate oil, taking into account the following components:
- viscosity;
- quality;
Diesel oil
When choosing a suitable mixture for diesel cars, take into account the specifics of their operation, which differs from gasoline units.
Diesel engines require consistency in the quality of the fluid used to ensure the longest possible engine life. The set of additives here is qualitatively different than for gasoline cars. Since fuel does not burn completely, the number of detergent and dispersant additives must be much greater.
Some are able to keep soot suspended, others reduce the formation of soot on pistons and cylinders. Due to the presence of a significant percentage of sulfur, in order to increase resistance to oxidation, additives are introduced into the oil that specifically protect against oxidation and the formation of an alkaline environment.
For naturally aspirated engines, experts do not recommend using oils of class below BI, or CD, according to various classifications. In turbodiesels, a class of CE or B2 is allowed. Turbocharged engines are more demanding, since not only are there high loads on the system, but there is also a need to ensure long-term operation of the turbocharger.
Another important point for diesel engines is the viscosity index. According to this indicator, summer, winter and year-round options are distinguished.
Oil for gasoline unit
The choice of fluid for such cars begins with determining the engine, as well as the natural conditions of the place where the car is used.
Today, power units have greater power and compression ratios, and therefore are able to operate in more severe conditions than before. This became possible, among other things, due to the fact that exhaust gas and toxicity standards have become more stringent.
Considering mineral water, semi-synthetics and synthetics, and also taking into account the latitudes where we live, experts conclude that the most suitable types are semi-synthetics and synthetics.
For most units, you can completely limit yourself to semi-synthetics, changing them as usual. But the more extreme the operating conditions, the more often replacement is required. What brand of oil is best to pour into the engine? In our conditions, when buying oil, you should first of all be extremely careful and pay attention not only and not so much to the brand itself, but to the quality and authenticity of the product. Therefore, reviews advise purchasing liquid only in stores that have a good reputation. Otherwise, there is a big risk of buying a fake.
Motor oils for different brands of cars
Well, to choose specifically which brand of oil is best to pour into the VAZ-2107 engine, you can look at the reviews of other motorists. Many people prefer the Lukoil brand, but there are also those who choose higher quality lubricants. However, having chosen one liquid, it is better to drive with it, since by changing the brand, you will be forced to additionally flush the engine and waste time, but the result will remain the same.
The best oil for Hyundai Accent
For car owners of this brand, the right choice depends on the year of production and engine number. Semi-synthetic 10W40 is suitable for most models. The only exception is the engine number D4FA, which runs only on 5W30 synthetics. What brand of oil is best to pour into the Hyundai Accent engine? Manufacturers recommend Liqui moly, Mannol, Aral.
Choice for Renault Logan
The opinion of manufacturers regarding which brand of oil is best to pour into the Renault Logan engine is to support ELF Evolution SXR 5W30 or ELF Evolution SXR 5W40. These are synthetic-based lubricants.
Suitable option for Nissan cars
Let's look at two Nissan models: Almera and Qashqai.
What brand of oil is best to pour into the engine? Nissan Almera is a model that has been produced for a long time. Therefore, for cars before 2000, mineral water 15W40 is suitable, and after 2000, synthetic 5W30 is suitable. For diesel engines, this brand could be Elf 5W40.
What about new models? What brand of oil is best to pour into the engine? Nissan Qashqai, for example, has been produced since 2007. For him, as for other new cars, the manufacturer clearly suggests using only 5W30 synthetics. Car owners, of course, have the right to choose a specific brand themselves, but most use original Nissan oil.
The best option for Opel
For older models, mineral water 15W40 or semi-synthetic 10W40 is suitable. But for the last years of production they choose 5W30 synthetics. So what brand of oil is better to pour into the engine? Opel recommends Mobil1, Liqui Molly, Motul to its customers.
The best oil for Toyota

The best oil in winter
Judging by reviews, winter engine oil is not currently used by car owners as such. Therefore, they pay more attention to the viscosity class. If the liquid has a name that contains the letter W, for example: 5W30, 5W40, and so on, then you can be sure that this oil belongs to the all-season class. You can easily use it all year round. The majority of drivers choose this type of oil. At the same time, when using oil in winter, you need to pay attention to the first number before the letter W.
If the low-temperature viscosity corresponds to the regional climate where the vehicle is operated and the battery with starter is in proper condition, then there is nothing to worry about. And you can also continue to use this viscosity class.
If you are not sure about the weather, then it is better to choose a lower temperature viscosity.
In this case, the following circumstances must be taken into account:
- changing the oil puts additional stress on the engine;
- fluid from the same manufacturer is compatible at different viscosity classes;
- used in the cold season must meet the vehicle manufacturer's recommendations.
In addition to viscosity and type, many motorists prefer using certain brands in winter. What brand of oil is best to pour into the engine in winter? Our most popular are:
- Castrol, which is highly regarded in most Eurasian countries.
- Shell Helix, which many consumers speak highly of.
- Xado also has excellent features.
- Zic has been trusted by car owners for many years.
- Mobil is a German leader recognized in many countries.
Lukoil oil is also known and popular among Russian consumers. But in winter it is better to use a different brand.
The number of offers on the market today is extremely large. For each car, up to several dozen brands found on the shelves of auto stores can be suitable. For winter, it is better to focus primarily not on cost, but on quality characteristics. If the car is stored in a heated garage, then the fluid requirements are significantly reduced. Then the usual all-season service will be sufficient, and there is no need to subject the engine to additional load by changing the oil composition.
