Gear oils 80w90 hl 5. Car oils and everything you need to know about engine oils

Before talking about the classification and main characteristics, it is necessary to find out what tasks this working fluid performs. Such oil is necessary for solving several problems:

• Parts lubrication. There are dozens of moving parts in the gearbox design. To reduce their wear, while ensuring correct and smooth operation, transmission oil is necessary. If it is not changed in a timely manner, a large amount of metal chips will form in the gearbox, which can disrupt the operation of the unit.
• Heat dissipation. Without gear oil, the parts of the box would simply overheat. High temperatures also have a negative effect on parts as well as their service life.
• Corrosion protection. Modern products in the composition include many elements that help to increase the protection of the metal from corrosion.
• Reduced transmission noise and vibration. The operation of the gearbox is associated with various noises that cause inconvenience to the driver and passengers when driving. Oil can significantly reduce the noise level.

As you can see, the use of gear oil is a must. It helps to extend the life of the gearbox, and also prevents breakdowns.

Oil Viscosity: Definition and Importance

In the store and in the market, drivers can find a huge selection of oils. Modern industry produces mineral, semi-synthetic and synthetic oils. Each of them has its own characteristics and features. When choosing products, you should definitely pay attention to such an indicator as viscosity.

This parameter allows you to determine if this fluid is suitable for use in a particular temperature range. Essentially, this is the ability of an oil to maintain fluidity between parts. We all know that this working fluid thickens with decreasing temperatures, making the lubrication process impossible. For this reason, of course, it is necessary to choose the right oil. You can always find recommendations for buying in the technical description of your car. Additionally, you can consult on specialized forums for your car model.

International SAE classification

How to determine the viscosity of the oil, because it is impossible to measure this parameter with a ruler or other tool. This question was asked by experts from the American Society of Engineers. The result of their work was the creation of a generally accepted standard. The SAE index indicates the viscosity of the oil, while allowing car owners to choose the products that are necessary for their foreign car. This index can be used to determine the highest and lowest temperatures at which oil can be operated.

According to SAE standards, gearbox oils are divided into two main categories:

• winter (in their marking they have the English letter W - Winter), for example, 70w, 75w
• summer (without index), for example, 80, 85, 140.

There are also all-weather oils (they are just being discussed), which in the marking have two numbers at once, separated by the English letter W. Such products can be used by drivers throughout the year.

In this marking, the first number (for example, 80W) indicates the viscosity class at low temperatures (also called winter viscosity). The second indicator after the letter W is the viscosity class at positive temperatures (or summer viscosity). The first number in the marking indicates the viscosity of cold oil, and the second - hot. The smaller the first parameter and the larger the second, the better. The small first number ensures the ease of movement of the gears in sub-zero temperatures, and the large second number guarantees the high strength of the film being created.

Oil comparison

When we have determined what viscosity is and figured out the principle of labeling gear oils, we can move on to comparing different products. So, the first number indicates the minimum temperature at which this oil can be operated. Thus, products 75W90, 75W85 and 75W85 have a common parameter (temperature of -40 degrees Celsius). The second indicator indicates viscosity at positive temperatures. For 75W85 and 75W85, this figure is 35 degrees Celsius, and for 75W90, the maximum temperature reaches 45 degrees.

If we compare the 80Wxx products with the 75W90 product, then the differences will already be in sub-zero temperatures. 80Wxx oils have a lower limit of -26 degrees. 80W90 products have an upper temperature limit of 45 degrees. The maximum lower temperature parameter is observed in 85W90. In winter, temperatures should not fall below -10 degrees for this type of oil to work correctly. A distinctive advantage of this oil model is the ability to perform its functions in extreme heat even above +45.

Products with an index of XXW90 are ideal for temperate climates. Oil 75W-90 is used in severe frosts. Properly selected gear oil will also affect handling. Changing gears will be much easier. The driver will have to make a minimum of effort.

When buying, you should also pay attention to the type of oil. For example, there is such a division:

• 85W-90 are usually thick mineral oils.
• 80W-90 is also a mineral oil, but with greater fluidity.
• 75W-90 - synthetic or semi-synthetic medium density.

As the experience of drivers shows, 75W-90 oil is optimal for a temperate climate. It retains its characteristics over a wide temperature range, and practically does not oxidize.

Main types

As mentioned earlier, in addition to viscosity division, the presented oils can belong to one of three groups:

• mineral;
• synthetic;
• semi-synthetic.

The first, as a rule, are used in old cars with a service life of more than 15 years. They are marked with the word Mineral. This is an environmentally friendly product, as well as the most affordable. At the same time, in terms of its characteristics, it is significantly inferior to the other two classes. Mineral oil quickly oxidizes and thickens when exposed to low temperatures.

Synthetic oil is deprived of all these shortcomings. The products have the best detergent and protective properties, and also include many additional additives that improve the characteristics of the oil. Synthetics work great at both low and high temperatures. The only downside is the high price.

Semi-synthetic products are a kind of "golden mean", as they have performance characteristics close to synthetics, but at the same time a more affordable price. Products are created on a mineral basis, but contain many additives.

Good to know: API classification

When buying gear oil, drivers may also encounter API markings. There is no single classification for quality, performance and application, but API is the closest to it. It contains a comprehensive assessment of the performance of lubricants.

Almost all modern cars use oils of the GL-4 or GL-5 group. The former are suitable for mechanics and gearboxes that use hypoid or helical-bevel pairs. Such oils are actively used in temperate climates. The GL-5 is suitable for harsh environments in a variety of gears. There is also a GL-6 group designed for the harshest conditions.

What to look for when choosing

The purchase of oil should be based not only on any classifications, but also on several other parameters. A quality gear oil should:

• prevent high friction and increased wear on the surfaces of gears or other transmission components;
• carry out heat dissipation;
• stop or minimize the oxidation process;
• do not react with water;
• retain original properties during long-term storage;
• reduce noise and vibration,
• do not emit toxic fumes when heated.

Oil on the label may meet your requirements, but if it does not fulfill the above tasks, then this will lead to gearbox failure. Here you should choose products from official manufacturers or well-known brands that have proven themselves in the market.

Regularly performing engine maintenance (changing engine oil and filters), car owners sometimes forget about an equally important vehicle unit: the transmission.

Indeed, the renewal of technical fluids in the gearbox, transfer case and gearboxes is carried out at least 10 times less often than in the crankcase.

But the consequences of untimely maintenance are the same: premature wear of the units and failure of the car.

To lubricate these units, special formulations have been developed, the characteristics of which differ from motor lubricants. Most popular formula: 80W90 gear oil, viscosity suitable for most vehicles.

Lubricants with these characteristics are produced by many refineries, we will consider the products of some of them.

How does a transmission work, and why does it need lubrication?

Let's look at the purpose of its main nodes.

Transmission

With its help, the ratio of the speeds of rotation of the input shaft and wheels changes. If the crankshaft is connected directly to the wheels, the speed of the car will have to be regulated only by the gas pedal.

The motor will stall at low speeds with the slightest load. To maintain torque at any speed, numerous pairs of gears of various diameters “work” in the gearbox.

To change the steps, rocker arms move inside, rotation synchronization is provided using friction clutches. All these mechanics work under conditions of increased loads and friction. You can't do without a specialized lubricant.

Transfer case and gearboxes

The transfer box (if any) is designed to distribute torque between the vehicle axles (in all-wheel drive versions). Can be fitted with a viscous clutch running in the same 80W90 oil.


Reducers, axle differentials. Constantly experiencing variable loads with multidirectional pressure vector. These units use 80W90 hypoid oil.

Characteristics and purpose of the transmission

There are two main tasks:

1. Ensure the specified operating modes of the transmission elements by lubricating internal parts.
2. Extend the life of the units.

To do this, lubricants must have certain properties:

In addition, an extended additive package is added to the mineral gear oil. These chemical elements preserve the natural base from natural wear and tear, contribute to the restoration of parameters after critical loads and maintain the acid-base balance inside the unit.

What is the difference between 80W90 GL4 and GL5?

According to the international API standard, 80W90 gear oil may have an index of GL4 or GL5.

According to the general trends in the assignment of quality standards, the higher the number, the higher the quality. That is, it can be assumed that GL 5 80W90 oil can replace the "four".

In fact, in addition to changing generations, this standard determines compatibility with certain types of transmission units. And it has a direct and inverse dependence on the generations of the car.

Let's look at the description of the classifier (API):

1. Oil 80W90 GL 4 is designed for direct, bevel, hypoid gears of gearboxes, transfer cases and manual transmissions. Mode of operation - moderate loads and medium speeds.
2. SAE 80W90 API GL 5 runs in the same units, but the load and speed levels have been changed to a higher level. In addition, this oil withstands short-term shock loads.

It would seem that since the release of the "five", you can safely pour it into the same transmission elements as the GL-4. After all, the characteristics of the new generation overlap the previous version.

However, the classifier (API) set the standard without reference to the design features of mechanical transmissions (and in some cases transfer cases).

If 80W90 is just a decoding of the SAE viscosity class, then API GL is a whole range of parameters, including the regulating environmental class.

GL4 accepts lead anti-wear additives. Since, according to environmentalists, lead is harmful to the environment, sulfur-phosphorus additives are used instead in the GL5 standard.

They do increase the environmental class, but do not interact well with copper. Not chemically, but mechanically. Phosphorus creates an anti-wear coating that is more durable than copper. As a result, the copper coating is erased.

Important! In gearboxes and transfer cases produced under the API GL4 standard, a copper layer is present on almost all models.

This means that replacing the transmission with a higher standard is possible if there are approvals from automakers.

Some manufacturers produce transmissions of the same standard, for example: "TM 5 80W Lukoil". And there are compounds that have two designations (GL4 and GL5).

Popular transmission brands in Russia

Domestic refineries produce enough technical liquids not to look for imported analogues. Given the mineral raw materials, and the absence of customs duties, the cost of such products becomes attractive. And numerous user reviews confirm the stable quality.

Transmission oil "Gazpromneft" 80W90 GL4

Designed for use in passenger cars, buses and trucks operating on the highway and commercial vehicles. It has approvals of Russian, American, Asian and European manufacturers.

It is used on the conveyor of such leading manufacturers as AvtoVAZ.

The only fundamental limitation is that Gazpromneft 80W90 GL 4 cannot be used in differentials and gearboxes with a hypoid gear.

Gear oil "Lukoil" TM4 (TM5) 80W90

TM4 is a series of universal oils for manual transmissions and transfer cases in passenger cars and medium-sized commercial vehicles.

Can be used in mobile commercial vehicles: including power take-offs. With the exception of restrictions on the environmental safety standard, it can be used in any generation of units.

Lukoil TM5 80W90 is a transmission oil of a higher standard, which has no restrictions in terms of ecology, but the lubricant is not used in obsolete transmission units. Especially if the gearboxes contain synchronizers.

It contains a number of imported additives from Lukoil partner companies. With their help, the scope of application of Lukoil 80W90 in equipment designed for the international standard GL5 is expanding.

Outcome

The modern range of domestic 80W90 transmission fluids allows you to save on the purchase of expensive imported analogues.

Among all lubricants for manual transmissions and other transmission components, 80W90 oil is perhaps the leader in popularity. This is if we take into account the central zone of Russia. Below we will analyze the characteristics and scope of gear oil with a viscosity of 80W90.

Deciphering gear oil 80W90

Let us briefly consider the main characteristics that gear oils with a viscosity of 80W90 have. The SAE J300 standard says the following.

1. The pour point before the loss of lubricating and protective properties is at the level of -26 ° C. When freezing below this temperature, the dynamic viscosity of the oil will exceed the acceptable limit of 150,000 csp accepted by SAE engineers. This does not mean that the grease will turn into ice. But in consistency, it will become like thickened honey. And such a lubricant will not only not be able to protect the loaded friction pairs, but in itself will become an obstacle to the normal operation of the unit.
2. The kinematic viscosity at 100 °C for this class of oil must not fall below 24 cSt.. It sounds strange in relation to the transmission units: the temperature is 100 ° C. If the gearbox or axle warms up to such a temperature, then most likely there are some problems in the transmission assembly, or the permissible load has been exceeded. However, the viscosity at 100 °C is taken into account here because the oil film is under enormous stress in the contact patches and can locally be heated to higher temperatures. And if the viscosity is insufficient, then the film will break down more easily and allow the metal to contact the metal directly, which will cause accelerated wear of the assembly parts. Indirectly, the “summer” part of the index determines the maximum allowable summer temperature, which for the oil in question is +35 °C.

In general, viscosity is the main indicator. It is he who determines the behavior of a particular gear oil in different temperature ranges.

Scope and domestic analogues

The scope of 80W90 gear oil is limited not only by temperature limits, but also by other properties, such as: ability to form a strong film, resistance to foaming and oxidation, service life, aggression towards rubber and plastic parts. In more detail these and other properties of gear oil are described by the API standard.

Today in Russia, 80W90 gear oils with API classes GL-4 and GL-5 are more common than others. Sometimes you can also find GL-3 class lubricants. But today they are almost completely discontinued.

Oil 80W90 GL-4. It is used in most synchronized gearboxes and other transmission units of domestic and foreign cars. Interchangeable with GL-3 class oils, but contains a more advanced package of additives, in particular extreme pressure additives. It has good lubricating and protective properties. Able to work with hypoid gears, in which the contact load does not exceed 3000 MPa.

Gear oil 80W90 class GL-5 according to API has replaced the class GL-4, already obsolete for new cars. Reliably protects hypoid friction pairs with a large displacement of axes, in which contact loads exceed 3000 MPa.

However, this oil may not always be used in gearboxes designed for the GL-4 standard. It's all about the very low coefficient of friction, which is achieved through an advanced additive package. Synchronizers of simple manual transmissions work due to the coefficient of friction. That is, the synchronizer is pressed against the gear and equalizes the speed of rotation of the shafts immediately before the gears enter into gear. Thanks to this, the transmission will turn on easily.

When running on GL-5 oil, synchronized gearboxes that are not designed for this standard often experience tight gear changes and a characteristic crunch due to synchronizer slippage. Although the car owner can see some increase in car power and a decrease in fuel consumption due to a noticeably lower coefficient of friction. Also, synchronizers fail at an accelerated pace on boxes that are not designed to work with GL-5 oil.

Other transmission units that require simple lubrication of the force-transmitting mechanisms may be filled with GL-5 oil instead of GL-4.

The price of 80W90 oils starts at 140 rubles per 1 liter. This is how much the simplest domestic lubricants cost, for example, the OilRight brand. The average price tag fluctuates around 300-400 rubles. The cost of top products reaches 1000 rubles per liter.

According to the old classification, the domestic version of 80W90 oil is called, according to the new one - TM-4-18 (similar to 80W90 GL-4) or TM-5-18 (similar to 80W90 GL-5).

Having traveled far from one tens of thousands of kilometers on various vehicles, I can say with confidence that the use of a special fluid with lubricating properties for the transmission is just as important as the use of engine oils for the power units of vehicles.

But comparing these two fluids is not entirely correct to the extent that gear oil has a completely different viscosity class and characteristics in general. The list of one of the most popular transmission lubricants can be safely attributed to 80W-90 oil, which will be optimal for regions with moderate frosts in winter and significant heat in the summer season.

Transmission lubricating fluids, as well as motor oils, are classified by the Society of Automotive Engineers (SAE, Society of Automotive Engineers). One or another class is assigned to lubricants depending on the viscosity characteristics and temperature conditions under which the oil is able to maintain its operating parameters. The 80W-90 marking is combined, so it is worth considering each marking often separately:

• The signature of the oil brand with the letter 80W (from the English winter - winter) indicates that the oil belongs to the winter range of lubricants and begins to solidify at temperatures from -25 to -30 ° C. For example, oil labeled 80W. The lower the number before the "W", the lower the pour point. Therefore, for harsh climates, it makes sense to select oils 75W, 70W and below.
• The subsequent number 90 indicates that the oil belongs to the summer range of lubricants. This gear oil will maintain its performance at temperatures of 35-40°C above freezing.
• Double or combined marking is used to designate all-weather lubricating fluids. The gear oil considered in this article is just the same all-season with combined marking.

As a result, it may seem that greases with a combined marking are the most optimal for use. But one should not be deceived and forget about the peculiarities of the climate in individual regions.

For hot southern regions, a truly combined 85W-90 lubricant with a positive temperature threshold of 40 ° C would be preferable. But, if vehicles need to be operated in cold winters, then the choice should be made on oils marked 70W, which can withstand sub-zero temperatures down to -55 ° C.

Oil characteristics

Technical and physico-chemical properties vary due to the fact that each oil manufacturer has its own formula for the additives used. From a practical point of view, this has little effect on behavior, since Standards and production requirements for all manufacturers are the same. Below are the characteristics of 80W-90 transmission oil (limits of some indicators are indicated depending on the manufacturer):

• density index when heated to 15 ° C - 0.9 kg / cc;
• viscosity when heated from 40 ° C - 137-144 cSt;
• viscosity index - varies from 98 to 142;
• pour point - 16-30°C below zero;
• ignition temperature — 179-230°C

Gear oils, like motor oils, are characterized by the presence of additives that make the oil a more viscous liquid. They are needed in order to ensure the normal operation of the transmission in various temperature conditions and to maintain normal operation in the event of a sharp temperature drop. In addition, additives protect against liquid evaporation, which adversely affects the operation of the transmission.

In addition to the above tasks, transmission lubricating fluid ensures silent and smooth operation of the gearbox. If the parts are not properly lubricated, it can make it difficult to shift the high-speed gear, which will lead to a decrease in the performance of the entire transmission system. Also, weak lubrication or its complete absence leads to the appearance of extraneous sounds and noises during the operation of the car and the gearbox itself.

Gear lubricants with a viscosity of 80W-90 stand out from the rest with their demand among motorists, they withstand the load effect well, and also retain their working properties at fairly low temperatures, for which many car owners fell in love with. More information about where, when and what kind of oil should be used is indicated in the vehicle manual, as well as on the canisters themselves and lubricant packages.

Group of gear oils GL4 and GL5

According to international API standards, gear oils are produced and produced with GL4 and GL5 indices. The number at the end of the index is directly proportional to the quality of the lubricant. Therefore, it is acceptable to assume that GL5 is better than GL4. In addition to the difference in oil generations, this index indicates compatibility with certain types of transmission systems. Oil with the GL4 index is applicable to cars with direct, hypoid, bevel gears of gearboxes and manual gearboxes. Optimum operation is achieved at moderate loads and medium speeds.

As for GL5 oils, they work on the same mechanical components and assemblies as GL4, but higher speeds and loads on the transmission system are already acceptable here. Unlike GL4, new generation oils are able to withstand short-term shock loads.

Also, these oils have different environmental standards. In the production of GL4 oil, the use of lead anti-wear additives is acceptable. Environmentalists consider the presence of lead harmful to the environment, so in GL5 oils it was replaced with sulfur-phosphorus additives.

This solution really helps to reduce harmful emissions into the atmosphere, but these additives interact worse with copper metals. The deterioration occurs at the level of mechanical work. Phosphorus additives create such a coating against wear that the copper coating on car parts simply begins to wear off.

Important! Gearboxes and transfer cases built during the API GL4 period have copper plating on the vast majority of models.

This indicates that the transition from the old to the new generation of transmission lubrication is possible only with special approvals from car manufacturers.

Prices

The cost of gear oils with a viscosity of 80W-90 starts from 137 rubles per liter container. As a comparison, we can cite the products of TNK TransHypoid, which will cost 539 rubles. for one litre. Gear oil 80W90 will cost even more - 855 rubles. per litre. And Ford 80W90 - 1300 rubles.

Conclusions from the article

• Gear oils 80W-90 are multigrade and are used at any time of the year.
• They have a high reliability.
• Wide operating temperature range.
• Acceptable transmission performance even at low temperatures.
• The use of additives that increase wear resistance and other operating parameters.
• Large selection of oils according to the climate, prices and other qualities.

The transmission is the integrity of the mechanisms that transmit the engine torque to the wheels, so that the car can go. Also, thanks to the transmission, the machine changes the traction force, can change the speed and direction of movement.

Periodic jamming of the gearbox and the inability to change gears indicate that the transmission units are out of order. In these cases, it is not always necessary to replace the unit itself, sometimes it is enough to prevent and replace the transmission fluid, namely oil. On average, transmission oil is changed after 50,000 km.

Before pouring gear oil into a car, you need to familiarize yourself with the parameters and characteristics of the protective fluid. Such information is written by the car manufacturer in the service book for the operation of the car.

Transmission oils are universal, all-weather, summer, winter, for cars with front and rear wheel drive, small trucks, jeeps and for heavy equipment coupled with city vehicles. Actually, you can already notice that their classification is similar to motor oils, however, they also have SAE gradation.

In the world, it is customary to call such oils Gear Oil, which literally means oil for gears.

Functionality of gear oils:

• heat removal from rubbing surfaces;
• prevention of wear of rubbing surfaces of parts through the formation of a protective oil film;
• neutralize wear products from friction zones;
• reduce friction losses in mechanisms with gear clutches;
• prevent corrosion of vehicle components;
• reduce noise, vibration and stress on gear mechanisms by filling the gaps between them.

Properties of gear oils:

1. anti-corrosion;
2. Antifoaming;
3. Extreme pressure;
4. Anti-wear;
5. Saving in relation to non-ferrous metals rubber elements of a car;
6. resistance to thermal oxidation;
7. Not toxicity;
8. Resistant to temperature changes without loss of viscosity.

As an illustrative example, consider 80w90 gear oil, which is in greatest demand among the consumer. As we said above, transmission oils, like motor oils, are subject to SAE classification. In the international community, such oils are usually equated with the J306 SAE standard. This is the main indicator of TM viscosity, which is based on the temperature properties of the oil (low and high temperatures). The marking of engine oils according to SAE is assigned an interval of 0 - 60, for transmission - 70 - 250.

Good quality gear oil works in any conditions, the higher its viscosity, the more reliable and durable the protective film for units. Gear oils with a lower viscosity are more fluid, they tolerate low temperatures better, but at the same time their protective abilities are significantly reduced. It is ideal to find a middle ground, so that the fluidity is good and the oil quickly fills all the microcracks and the protection film is thick enough and reliable. To do this, modern gear oils are equipped with additives, by analogy with motor oils. The property to act as a sealant is obtained during production, before the addition of additive packages.

After adding additives, TM fluids are divided into categories: unthickened and thickened.

How to decipher gear oil 80w90?

This 80w90 transmission fluid is deciphered as follows:

• Letter W - winter(example 80W) - does not lose its properties at a temperature of -26 degrees Celsius, while maintaining good fluidity.
• 90 - summer- the oil is not subject to overheating at a climatic temperature of + 35 degrees Celsius. This should not be confused with motor oils, which work in the engine and are less dependent on ambient temperatures.
• 80W90- all-weather (combined) gear oil, therefore there is a double marking.

Ideal operating conditions for 80w90 gear oil are from -26 to +35 degrees.

Reference! As in any combinatorics, there are no ideals in combi-TM, therefore, speaking of all-weatherness, it must be taken into account that there are limiting points for climatic temperatures. For example, the most frost-resistant oils among all-weather oils - 75w80 and 75w90 - their limit is from -40 to +35, and the most heat-resistant 85w90 with an interval of -12 to +40.

Characteristics 80w90

Despite the fact that 80w90 gear oil is produced by different manufacturers, their characteristics are uniform. Only additive packages can vary, which each manufacturer adds at its own discretion, in any case adhering to world standards, since otherwise the TM will not pass certification.

• viscosity classification according to SAE - 80w90;
• density 0.9 kg/m3 at +15 degrees Celsius;
• kinematic viscosity coefficient from 14 to 19 cSt at workers +40, it all depends on the package of additives used;
• viscosity can change from 98 to 142, again due to the additive package;
• limit temperature for minus in the gearbox from -16 to -30;
• flash point from 179 to 230.

Information about all the characteristics of gear oil 80w90, each manufacturer writes on the packaging. as in motor oils, the main parameters of 80w90 are applied on the front label; TM - 4 80w90; TM - 4 SAE 80w90 or SAE 80w90. The domestic manufacturer also uses the SAE abbreviation, showing that the product belongs to the world classification and has been certified.

Reviews about 80w90 - what do car owners say?

Guest 1. I have a new Priorka, so I immediately came to Lukoil. They were filled at the factory, although there is no such oil for sale, these are purely factory wisdom, and so right now on TM - 4, while everything is fine, the machine does not puff, does not groan. There, Lukoil writes on the transmission 80w90, one for the front drive, the second for the rear, there are station wagons, but it’s better to take it for yourself. You need to take semi-synthetics, there is a good ratio of synthetics and mineral water.

Guest 2. I have been riding the mineral TM with a five since my birthday, I don’t know grief. We start in the winter, we don’t fry in the summer, the box does not jam, the bottom does not ring. A song, not a machine. By the way, I switched to Lukoil from TNK, there are no problems there either. Honey and not oil, so succumbed to the general hype. I’ll probably switch back to TNK, there are a lot of fakes in Lukoil. By the way, recently the voting was on the official website of "Behind the Wheel", so I voted for Lukoil 80w90 transmission mineral oil, and I was not ashamed, the domestic manufacturer was driving.

Guest 3. And I, too, for Lukoil 80w90, my husband taught me to drive in a six, so we poured TNK, he said that it was excellent oil. He showed me the characteristics, as it was written there - TNK 80w90 transmission oil starts up without problems at -38. Actually, it started up even at minus 35, we have such frosts all the time. It’s a pity I had to leave him, he gave me Kalinka, so TNK is not suitable, we tried imported mineral water, but it turns out expensive, but he still wants Priorka for himself, so we definitely go to Lukoilovskaya semi-synthetic. We are for a domestic manufacturer, we support, so to speak.

Guest 4. Now I have filled in ZIC 80w90 gear oil, everyone is blaming it for anything, but I like it. The car already sighed, as if the box was stuck all the time, but right now, like clockwork.

Guest 5. ZIC 80w90 is the very thing, but I still don’t recommend Lukoil to anyone.

Guest 6. Excellent Lukoil oil and everything matches what is written on the canister. We changed it already 35 thousand were knurled, so in general everything is fine - perfect protection. But I myself read about ZIC on the internet, everyone blames it, that engine oils, that transmission.

Guest 7. The box jammed before - the multitronic immediately thought of oil, it turned out that the matter was in the box itself, it was time to repair it. Not cheap of course. After the zik, I still went to the liquimolly, and then I felt sorry for the money, I decided to try the zik again, especially since the seller gave his head for cutting off, that he had his own oil. Now I’m saying for sure that for modern cars and automatic machines, ZIC 80w90 transmission oil is SUPER. As for the backs, I can’t say, I didn’t ride on such.

Guest 8. I have a rear-wheel drive, in addition to the four, there is also a Volga 21, it flies like new and without forced engines. So for us, for rear-wheel drive, the most ideal is TNK 80w90 transmission oil. And the additives there are normal, and there are no fakes, who needs it, and the quality is decent. Lukoil is nothing, but their mineral water is a little expensive, and semi-synthetics are not needed for the backs, and the Volgas are even contraindicated. TNK itself is both quality and little money.

Judging by the reviews of car owners, everyone makes their own choice. Despite the existing negative reviews about Lukoil, many still choose it, when choosing, you only need to check better and not fall for a fake. ZIC and TNK 80w90 oils are also popular.
