The class of transmission oils for a long time was the most conservative. In the gearbox or bridge, the conditions of oil is softer than in the engine - there are no temperature drops or penetration exhaust gases. Therefore, transmission oils were a mineral base with mineral additives designed to protect the gears from welding.
In the Soviet Union, the emergence of dyed transmission oils occurred with commissioning T-34 tanks, the highly loaded transmission of which simply did not endure work on the Nigrol then (in fact, the oil distillate in the mixture with resins). It is sulfur and phosphorus provided by mineral transmission oils such a characteristic smell.
Varieties Transmission oils
However, with time and transmission has undergone changes. First of all, synchronizers appeared - and their bronze rings were destroyed in high-ground oils, and had to develop contamination additives.
The mass spread of hypoid gear (hypoid gear is an angular gearbox, the axis of the leading and driven gear of which is lying in different planes), high contact loads in which oils required oils with extremely high anti-ray properties, demanded the creation of a separate class of transmission oils. With the tightening of environmental requirements, it also affected the transmissions - low-visual synthetic oils were released into the arena, reduced mechanical losses in gearboxes.
Modern classification
As for motor oils, the standards of the American Institute of Oil (API) are for transmission adopted classifications.
GL-1 groups are lubricants for low-loaded transmissions on the mineral base with a minimum package of additives. In no one modern car Similar oils do not apply. Irrelevant for motorists and rich in anti-wear additives GL-2 oil - they are used in low-speed worm gearboxes.
For medium loads in low-speed transmissions, oils of the GL-3 group are designed. This group of transmission oils is used in mechanical boxes gears and spiral conical gearboxes of leading bridges due to the increased content of anti-wear additives, but are relevant for cargo transport.
In the passenger transmissions, the oils of the GL-4 group are operating, containing both anti-wear and anti-rack additives. For high revolutions The gears of the gearbox are whipped foam, which significantly reduces the quality of lubrication - and the transmission is lubricated exclusively by splashing. In gearboxes, such oils are applicable with limitations - they are poured only in spiral-conical transmissions or in hypoid with extremely low axle axes.
Oils of the GL-5 group are intended solely for hypoid gears. They have the highest content of antifriction and contamination additives, and in some cases of the oil of this class are flooded in the gearbox. However, consider that not all GL-5 commercial oils are compatible with synchronizers (first of all it concerns mineral oils). To clearly indicate the possibility of working with synchronized MCPs, such oils are marked as GL-5 + or GL-5 SL.
"Outside the standard" designations such as GL-4 + or GL-4/5, which are used for oils that have complex packages of anti-promotional additives that make them use in hypoid transmissions possible, but complete compatibility with synchronized manual transactions is also preserved. First of all, such oils are relevant for front-wheel drive cars, where the gearbox and differential are in one Carter - in the line of transmission oils Elf. And TRANSELF NFJ, and TRANSELF NFP are marked as GL4 +.

The main characteristics of transmission oils
The viscosity of transmission oils is classified according to the SAE standard, familiar with engine oils. In transmission oils, digital designations of viscosity ranges are shifted relative to the notation of the motor. Oil 75W-85 in low-temperature and high-temperature viscosity close to motor oil 0W-30.
The game with viscosity of oils in the transmission has no less restrictions than motor oils. More liquid oil will improve the operation of the gearbox in winter, while the transmission is not free, but at the same time, in working mode, the oily film will provide the strength of the oil film below the required (saving resource at the beginning of the movement, we will simultaneously reduce it after warming up).
The more thick oil is poured into the worn boxes and gearbox to disguise the characteristic war - but it is worse than splashing and worse penetrates the gaps, which theoretically increase wear, until the clearances are sufficient for this oil. But since it is resorted to such measures already with significant wear, fill more dense oil It is really necessary to maintain the residual transmission resource.
The main characteristics of the transmission oil is the minimum load of welding. This value determines at what point the anti-promotional additives will stop working, and local overheating and welding the surfaces of the teeth gears will begin. It is determined experimentally on special carwhere the loaded cone rotates emphasis in several steel balls - the control load becomes the balls are welded to the cone.
Non-normalized indicators on the bulk and wear demonstrate the quality of the oil in sparing conditions - the load is estimated at which the transmission still works, but with the destruction of the surfaces of the teeth (zadira), and the change in iron and non-ferrous metals in oil (wear) is measured. First of all, it is interesting to wear for non-ferrous metals, since synchronizers have a smaller margin of strength than gears.
Best representatives of their class
For the correctness of comparison, we will take modern transmission oils with a viscosity of 75W-90 - they are universal, having and sufficient high temperature viscosity, and keeping fluidity in winter.
Motul Gear 300.
Complete synthetics on an ester basis, designed for high loads, which is confirmed by compliance with the requirements of the US Department of Defense (MIL-L-2105D). Classified by the manufacturer as GL-4 / GL-5. Creates a solid oil film that can withstand heavy loads than other synthetic oils. It provides one of the highest loads of welding in its class. For powerful cars Motul Gear 300 will be the best choice. It also has excellent low-temperature fluidity, which is good for Russia.
Castrol Syntrax Universal Plus
This oil is cheaper than Motul, but closely approaches it according to the degree of protection in extreme loads. At the same time, viscosity at low temperatures, although fits into the requirements of the SAE classifier for the stated values, higher than that of a French competitor, which for harsh winter is not the best way. At the same time, this oil is better maintaining viscosity when heating, and this adds a pair of kopecks into a piggy bank of the transmission resource. A good choice for the economical owner, which is calculated for a long time to operate the car.
Liqui Moly Hochleistungs-Getriebeoil
Traditionally for the company transmission oil It has a difficult name, but it is interesting, it is primarily a powerful antifriction package and stable viscosity - this oil is capable of large runs give fuel savings. The API group is determined by the manufacturer as a GL-4 + (GL-4 / GL-5) - it can be confidently pouring in the gearbox and on the front, and on rear drive. Also, the oil boasts ZF, Volkswagen and Ford tolerances.
Mobil Mobilube 1 SHC
GL-5 group, combining a powerful package of contamination additives with a careful ratio to synchronizers of non-ferrous metals. It is interesting to see on the Mercedes-Benz or Scania approval label and the Yaroslavl motor factory for boxes working together with YMZ diesel engines.
One of the highest rates of oily film strength, high load of welding and bully - these are parameters characterizing the operation of oil in harsh environments. In the average conditions, it will be even more efficient than Motul, losing it when heated above 100 degrees when viscosity drops sharply. In winter, it is densely - at Castrol, it wins in this plan.

Transmission oil 75W90, like the motor - this is, without which the "life" of the car is impossible. This type of oil is designed for use in certain modifications of gear shift boxes. mechanical type, differentials, dispensing boxes, to work the leading bridges of a number of models of both freight and passenger cars. The transmission oil has a classification similar to the division on the varieties of engine oils. However, it should be noted that this lubricant is not suitable for use in automatic transmissions for which you need to use automatic transmission fluids recommended by manufacturers.
Basic properties 75W90
It must be said that in the domestic market lubricants Presented a number of modifications 75W90 from different manufacturers, among which Motul, Energear, Teboil, Zic, Xado, Mobil, Castrol, and other oils different manufacturersOf course, somewhat different by properties and, of course, have different prices. According to motorists and specialists in this area, such a type of oil from a reliable manufacturer will have a high rating and wonderful specifications.
Transmission oil 75W90 is synthetic, although a number of dealers and distributors are positioned as semi-synthetic. Semi-synthetic differs from synthetic content in base modification From 20% to 40% of the synthetic substance. Also grasintetic contains as a basic mineral substance (78-45%) and additives (2-15%). In case of synthetics in base oil It contains only a synthetic base. In addition, synthetic basic lubricants by method of obtaining can be:
- hydrocracking (most common as the basis of commercial synthetic oils; synthesized from mineral oils by complex chemical reactions in the presence of catalysts - hydrocracking);
- polyalphaolefins (fully synthetic, obtained in the process of organic synthesis of hydrocarbon gases);
- specific synthetic (not related to the group of hydrocracking oils, nor the group of polyalphaolefins).
High-quality oil - the pledge of the durability of the vendors of the car Thus, for the production of synthetic oil, 75W90, either a base hydrocracking agent with additives, or polyalphaolefins in a complex with appropriate additives, which give the necessary characteristics and parameters. Therefore, the main properties of 75W90 are as follows:
- suitable for working under both high and low temperatures;
- protection of transmission and prevention of its production;
- stability to oxidation in conditions of significant temperatures;
- dissolution of deposits;
- excellent low-temperature properties;
- inertia to polymeric seals;
- increasing the efficiency of the transmission;
- reducing friction in the working nodes of the transmission.
The semi-synthetic is characterized by other distinctive properties.
Parameters 75W90 by SAE and API
According to the international classification of SAE, transmission oils are divided into several varieties depending on viscosity. Thus, the synthetic 75W90 has a "75W90" viscosity index, in which the first figure "75" means the maximum minus temperature at which the lubricant retains its viscosity properties. According to reference data, this temperature for this type of oil is -40 ° C.
And the number "90", in turn, indicates the maximum positive temperature in which the lubricant in question retains its viscosity properties. According to reference data, this temperature for the transmission oil 75W90 is +35 ° C. The presence in the viscosity index of digital values \u200b\u200bas "winter" and "summer" viscosity indicates that synthetics 75W90 is the all-season lubricant material.
It should be noted that high-quality 75W90 should remain in the class of viscosity "90" even after the corresponding transmission oil test is carried out in accordance with SAE standards.
In addition to the classification on the SAE system, there is still a division of transmission oils through the API system with the "GL" index (in russian version - Index "TM"). According to this classification, the domestic market presents the following modifications of lubricant 75W90: GL- 4, GL- 3/4/5, GL- 4/5. Thus, according to the international system API 75W90, the following indices may have:
Transmission castrol oil C API index GL-4 - GL-3 (TM-3) - Used for operation in medium-harsh environments mechanical gears spiral-conical type;
- GL-4 (TM-4) is used to operate hypoid type gear at considerable speeds and minimum torque, as well as with large torques in combination with low speeds;
- GL-5 (TM-5) is used to operate hypoid type gears with minimal torque in combination with high speeds, with intensive loads on the gear teeth.
In addition, it is important to know that the combination of indexes, for example, GL-4/5 or GL-3/4/5, speaks of universality for gears different types And for a wide range of their working conditions. The possibility and efficiency of application for the transmission of a car modification 75W90 stipulates the manufacturer vehicle In the appropriate manual.
All motorists know that the maintenance of their vehicle requires special consumables. This is a motor and transmission oil. Unlike the engine lubricant, the second type of consumed material is poured into the gearbox. It promotes the protection of moving gear elements from mechanical wear.
Motor oil requires an attractive or replacement much more often. In some new foreign cars, during maintenance, the transmission oil is not provided at all by the manufacturer. But when repairing the transmission, as well as in all old-sample cars, there is a need for the use of the presented tool. What transmission oil is better to pour into a gearbox, the advice of experienced car mechanics will help. There are several generally accepted recommendations.
Overall characteristic of oil species
In the cold period, the inappropriate oil will quickly thicken. At the same time, the system will work "in dry" for a while. The surfaces of the movable parts will be worn, which will lead to the need to repair or full replacement mechanism.
Since the transmission oil is consumed slowly, all-season consumables are very popular. They do not have to change every six months. The cost of servicing the transmission will be smaller.
The remaining varieties (summer or winter oil) are used under special climatic conditions when constant ambient temperatures are held throughout the year.
Lubricity
Considering what transmission oil is better for VAZ, BelAZ, foreign cars, and so on, a few words about the lubricating ability of these funds should be said. Eliminate 6 classes of represented consumables.
For each type of vehicle, its specific type of substances is applied. For ordinary passenger cars, the GL-4 and 5 label is suitable. If the machine has front-wheel driveThe GL-4 is suitable, and rear-wheel drive models - GL-5.
There is no big difference between these two classes. In GL-5, simply above the concentration of anti-promotional additives. Therefore, if the car is operated at elevated loads, it is better to give preference to this class of lubrication. For conventional driving conditions, you can apply for GL-4 transmission.
Results of autotests
Experienced auto mechanics advise to apply transmission oil, which recommended the manufacturer of the vehicle. Modern foreign cars pass a series of tests and tests. After long-term studies, the technologists determine the best gearbox oil. Therefore, owning a foreign car, you should familiarize yourself with the management of the use. There is clearly spelled out the maintenance procedure for this model.
Many domestic drivers are interested in which transmission oil is better for Niva, VAZ-2110, VAZ-2114, etc. Experienced auto mechanics argue that in this case it is quite suitable for consumables GL-4 with a class of viscosity 75W90, 80W85, 80W90.
It is also important to consider the quality of this product. To avoid premature gearbox breakdown, you need to give preference to the means of proven manufacturers. And to avoid buying a fake, it is better to access the licensed dealers.
Test results of synthetic oils
By studying the question, what transmission oil is better for VAZ-2114, "Niva Chevrolet", "Lada" of the latest models, etc., should consider the most sought-after synthetic agents. If the mileage of the car is small, it is worth to give preference, according to auto mechanics, such means like ZiC GF TOP (700 rubles / l), Castrol Syntrans Transaxle (760 rubles / l), Total Trans Syn Fe (800 rubles / l) .
Their turnover and antifriction qualities are pronounced. This allows you to apply the funds presented in cold winters, the big heat in the summer. Non-failed additives allow us to apply the supplied consumables even in conditions of high load. Experts identify these transmission oils as the best of synthetic means.
User reviews about synthetic oils
By studying the question of which transmission oil is better for VAZ-2110, VAZ-2114, "Lada" and other domestic car brands, buyers should be considered. They argue that by applying the funds listed above, it is possible to significantly extend the life of the gearbox.
At the same time, the work of this system becomes almost silent and easy. The engines work faster, the vibration decreases. The car is easy to start even in winter. The only disadvantage is the high cost of such funds. But during operation, the price of oil turns out to be justified. It is better to purchase a reliable tool than subsequently carry out costly repair of transmission.
Opinion of experts on semi-synthetic oil
By studying the question of which transmission oil is better for "Niva Chevrolet", "G8", "dozens" and other domestic cars with a small mileage, the advice of experts on semi-synthetic means should be taken into account. Their cost will be less than synthetic tools, but non-imminent.
If new domestic car There is a small mileage, the consumables of the presented type will be preferable. The best experts are called Liqui Moly Hipoid Getriebeoil (750 rubles / l), ELF TRANSELF NFJ (600 rubles / l), THK TRANS GIPOID Super (900 rubles / l).
Each tool is designed for a specific type of gearbox. But there are universal varieties. Auto mechanics highlight high performance features Presented funds.
Lubricants are very important for each car, but choose good liquid It is not easy. We spent the test of transmission oils and prepared for you its results. The material will also be in detail it is described as precisely as expertise and the test of transmission oils.
Car transmission oils are necessary to lubricate in contact details in complex nodes and mechanisms. Thanks to this, their resource is extended and the need for expensive overhaul is postponed. All sorts of transmission fluids are sold in stores, and the results of our expertise will help you to make the only correct choice.
Features of the dough oils
Transmission fluid intended for lubricating gears acts as a prevention composition. It creates a special protective layer that prevents the formation of scaling on the surface and welding metal parts upon contact. In this regard, the quality of the protective properties of fluid in hard working conditions will depend on the wear resistance and the resource of the gearbox.
Specialists for the service station have to regularly engage overhaul Transmissions failing due to improper maintenance or use of inappropriate oil. Thinking about it, begins to interest the choice best oil. Pick up the optimal fluid helps the results of the examination conducted by experts in special conditions.
Modern gearboxes are very complex in the device, so for their normal functioning requires high-quality and regular maintenance - it involves replacing the transmission fluid. In the assortment of oils sold in the markets and in auto shops, not a disassembled motorist is easy to confuse. To facilitate the task of choice, we have prepared for you the results of an interesting test of transmission oils.
Properties of lubricating liquids
Specialists define properties car oils Taking into account their performance and features arising during the operation of the fluid. Among the main operating parameters of lubricants for the transmission, the following are allocated:
- fluidity;
- physiochemical properties;
- detergent;
- lubricating properties;
- temperature;
- anti-corrosion;
- antioxidant.
Producers of transmission oils use special additional components aimed at improving basic characteristics liquids. Thanks to them, the fluid provides the following advantages:
- neutrality to water and rubber seals;
- wear resistance of parts;
- preventing the appearance of jackets on the toothed elements;
- antispicious properties;
- incompetence oxidation;
- non-toxicity.
Motorists are usually guided by the reviews of familiar or read specialized forums before buying a new transmission oil for the machine.
How are lubricants classified?
Transmission oils, the test of which we spent, are classified into several categories, as well as all fluids differ in a number of parameters:
- kinematic viscosity;
- dynamic viscosity at low temperatures;
- operational characteristics.
Transmission fluids that have the best indicators and those considered universal belong to the fifth group. Today on russian market And all over the world use the system of dividing the viscous properties of SAE J306 transmission fluids. In this classification, the properties of lubricating materials on fluidity are separated in detail depending on the temperature.
According to the American classification, all transmission oils are divided into nine categories:
- 4 winter oils 70w, 75W, 80w and 85w;
- 5 Summer 80, 85, 90, 140, 250.
There are also all-season fluids, on the label of which both parameters are specified immediately, for example, 85W-90. Economically more beneficial to use all-season fluids, which serve until two years without replacement. In our test, transmission oils of labeling GL-4 participated.
What was checked during the examination?
The conditions for the use of transmission fluid are not so tough as motor oil. At the same time, for the normal functioning and long-term service, the node still requires a special lubricant capable of carrying workflows. During the test, the creation of an oil film that reduces wear and preventing the appearance of bumps on rubbing parts was checked.
The main goal of our examination was to identify differences between lubricants of different manufacturers, and not price, but in the main performance, taking into account the requirements for oils.
After check, we made sure that the difference in the results is so great that the test was not done in vain. We also learned that a higher price is not a higher quality indicator.
For example, Motul Gear 300 oil turned out to be the best in the following characteristics:
- the formation parameters of the debt;
When checking for wear, no oil of the TM -5 group could not be surprised (we were guided by GOST). Probably the cause in the fall of phosphorus and sulfur concentration in the initial raw materials. It is impossible to unequivocally talk about a negative result, since imported lubricant for the CAT was checked, to which Soviet standards cannot be applied.
In the process of tests, the results were revealed, some of which confirmed the feeding of lubrication to wear resistance and prevent the loop. For wear resistance, you need a buffer between rubbing elements.
How was the examination?
When checking transmission oils on tribological parameters, special laboratory equipment was used. The technology of verification of the main operating parameters is based on the use of the mechanism equipped with four metal balls in oil tank.
One of them moves and comes into contact with the rest of fixed balls. This specifies a certain speed and additional pressure of pressure. The information is read from the contact points of the balls. The resulting results were subsequently compared with GOST 17479. 2-85.
In Guest, there is a concept called "Critical Load". The phenomenon is characteristic when the lubricating film begins to collapse and direct contact of contacting elements occurs. Of course, imported producers are not focused on the requirements of the GOST, but for Russia, the verification of such parameters is the norm.
GOST accurately does not indicate special requirements for critical loads for oil intended for transmissions. In this regard, it was checked how long the oil film would withstand increased operational loads.
As for the viscosity index, it was evaluated in two parameters: at operating temperatures, kinematic, and at low temperatures, dynamic viscosity was measured from 40 to 100 degrees.
The definition of viscosity coefficients made it possible to determine the properties of the oil. The higher the viscosity, the more high the load on the motor. The lower dynamic viscosity, the better the components of the box are warmed up and the move. Persecution parameters are also played with an important role: the lower the temperature of the thickening of the oil, the better.
Motul Multi ATF.
This transmission fluid It is considered a high-tech product with a wide range of use. Lubrication is suitable for power steering and automatic transmissions. As the basis for this fluid acts synthetic oilcontaining special additives with antioxidant and anti-inflammatory properties. The product works effectively under the influence of different temperatures, both high and low. Among the features high lubricants are highlighted, positively affecting the minimization of friction. Also, oil causes good gear protection.
When using Motul Multi ATF oil, speeds are switched softer and smaller.
This oil corresponds to its collections by the API GL-5 class. This liquid is intended for mechanical transmissions of any design - with teeth or hypoid. You will learn from a separate material on the site.

It provides reliable protection against gearbox wear and all transmission details that are subjected to loads. Due to the synthetic base, the liquid is allowed even to the strongest frosts.
Oil is performed using hydrocracking technology. The liquid includes the latest unique additives having high operating efficiency. The test showed that ZIC lubricant DEXRON III. Promotes high protection of working parts that are forced to transfer high operational loads. As for the viscosity index and operational parameters, they are high enough. The liquid utilization is reduced to automatic boxes Transmissions.
CASTROL SYNTRANS UNIVERSAL PLUS SAE 75W-90
This oil has a synthetic base and contains a lot of additives, which cause good antioxidant properties and performance. Examination showed a high level of wear. Oil is suitable for hypoid gears and cylindrical. Among the advantages of liquid, Castrol Syntrans Universal Plus SAE 75W-90, highlight the ability of its functioning in a wide temperature range. Oil in transmissions with synchronizers are used, and the synchronization process with this oil is much facilitated.
Stable operation of the vehicle is possible only when using high quality oil in automotive nodes. Transmission machine oil They deserve the closest attention of motorists, but now more use the motor.
Transmission oil lubricates the gears of car in the transmission nodes - steering gears, leading bridges, handouts, gearboxes and power take-off. Such oils reduce friction losses and reduce wear in parts in the nodes of the transmission, cooled and protected from corrosion driving parts.
Transmission oil is intended:
- to reduce the cost of energy for friction,
- to protect parts from wear and breakdowns,
- to reduce vibration, shock loads and noise,
- to remove wear products from the friction zone.
Transmission oils must have excellent viscosity characteristics. They fill hydraulic system, Lubricate mechanical and hydraulic transmission nodes of industrial machines and gearboxes with gear and worm gears.
The viscosity of the oil is selected depending on the operating conditions:
- maximum - to prevent losses through sealing parts,
- minimum - to start transmission nodes at low temperatures and reduce friction losses.
When using high-quality transmission oil with good characteristics Significant economy of fuel.
Types and differences between GL4 and GL5 tolerances
Transmission oils are divided into 5 main classes. GL4, GL5 belongs to a new class, which appeared thanks to the transmission with hypoid transmission combined in one case. This design was required that two incompatible oils could not be mixed with each other. It developed a class of oils that satisfy the requirements for different classes.
The new universal class of lubricants is used simultaneously in leading transmissions and checks:
- With GL5 oils, the operation of the hypoid transmission becomes especially reliable at high voltage and shock loads.
- GL4 oils are designed mainly for operation in transmission boxes with front-wheel drive. This species contains twice as fewer gray-phosphoric additives that create a protective coating on rubbing parts.
The GL4 / 5 marking is used by Asian manufacturers, on the materials of European production there is a GL4 + designation. Some motorists consider these oils belonging to different classes, but they are mistaken.
Transmission oil 75W90: synthetics and semi-synthetic
The basic semi-synthetic product modification contains 78-45% mineral, 20-40% synthetic substance and 2-15% additives. The basis of synthetic transmission oils is only a synthetic base.
