Is it possible to pour into the gearbox the oil that fill in the engine? (Sergey)

Sergey, good afternoon. This question interests many novice motorists and now we will give it a full answer.

Is it possible to pour motor oil in the checkp?

The answer is unequivocal - no. Motor fluid Not intended for use in the transmission system, as well as transmission oil for operation in the engine. The use of mm (motor consumable) in the gearbox may result in irreversible consequences. Most likely, in this case, the unit simply fails.

It must be remembered that the consumables are manufactured under a certain type of unit, that is, the engine or gearbox. In addition, they have different additive packages, which is also an important factor.

The chemical elements contained in the transmission fluid are intended for certain purposes, respectively:

• such a liquid will not be able to perform the functions assigned to it, since it is not initially used for those purposes;
• like consumables can negatively affect the operation of the engine or gearbox, for the same reason for the inconsistency;
• in the structure of the consumable substance, components are used that can adversely affect the performance of certain elements of the system, that is, they can destroy them and so on.

These are just a few reasons why we do not recommend that you use inappropriate MM. As you understand, it is relevant for both the engine and the PPC. In any case, if you poured such a material into the system, then you will have not only to merge it. After that, the system will need to be very thoroughly rinsed from the remnants of an unnecessary substance. It must be done very carefully, because even the remnants can negatively affect the functioning of the unit.

• use only mm mm, which is prescribed and recommended by the manufacturer;
• use only high-quality oil, it will stabilize the operation of the motor or gearbox, as well as increase their operation resource;
• use only the corresponding MM (in order not to confuse, the oil for mechanical transmissions is marked as MTF, for automatic gearbox - as ATF, while motor oil marked as Motor Oil);
• to force aggregate Always worked well, mm must be changed exactly on time, so we recommend complying and not to increase the interval between replacements;
• buying a poor-quality substance subsequently will be the cause of more serious breakdowns, so we do not advise you to save, acquiring the products of the unverified manufacturer.

In the MCPP, Honda is poured either the original and changes after 50 thousand or engine oil, which changes in 20 thousand. There is no conventional transmission fluid - threatens the failure of the box!

Video "All about transmission fluids"

Detailed information on transmission fluids is presented on video.

At first glance, it seems strange that someone in principle will ask in such a question. After all, the difference between the average motor and transmission oil for the manual transmission is not so critical to search for savings in such a sophisticated solution. Another thing is machine guns. Below will look at whether the engine oil can be poured into the box.

Engine oil in automatic transmission

It is difficult to even assume that why a travelow owner in a right mind will pour into a expensive automatic transmission in principle unsuitable transmission oil, not to mention the engine. We strive in theory than fraught with the use motor lubricants in automatic transmission.

Lubricants for automatic boxes Transmissions (so-called ATF fluids) are actually closer in its properties to hydraulic oils than to the motor. Therefore, if there was a question about the use of "spindle" or other hydraulic oil in the machine, here it was possible to think about some interchangeability.

Engine oil is quite different from ATF fluids.

1. Inappropriate temperature. Liquids for automatic transmission even in severe frosts retain an acceptable fluidity relative to engine oils. Considering if the oil thickens to the consistency, for example, honey, then hydraulics (ranging from the hydrotransformer, by pumping the hydrophone) will be partially or completely paralyzed. Although there are such winter oilswhich remain sufficiently liquid and at very low temperatures (0W standard). So this item is very conditional.
2. Unpredictable work under the influence high pressures. One of the mandatory conditions for normal operation of the automatic transmission is the predictability of oil behavior under pressure. The box-machine is the most complicated mechanism consisting of an extensive hydraulic channel system. In each channel its own, strictly normalized, pressure values \u200b\u200band flow rates. The fluid should not be simply incompressible and well transfer the force, but also in no case to form air stops.
3. An inappropriate package of additives that hurt the box. The question is only in which the consequences will be shown. The mechanical part in the automatic transmission operates with high contact loads with which the engine oil at the peak will not cope. Zadira and chipping teeth - the question of time. And the rich additives of engine oil, which are designed for 10-15 thousand km run in the engine (and in completely others than in the automatic transmission conditions), can fall into the sediment. Deposits in the hydraulic block will certainly cause problems.

In general, it is possible to pour the engine oil into a box with a machine gun only as a sophisticated and expensive experiment: how long will the automatic transmission on the engine oil. For normal operation in automatic gearbox It will not even suit the most expensive and technological engine oil.

Motor oil in the manual transmission

Immediately we note that the engine oil in the car VAZ of classical models can be poured. This was written even in the factory instructions of early models.

On the one hand, a similar solution was based on the lack of good transmission oils in the 80s when it started mass production Zhiguli. Lubricants such as high viscosity, which was acceptable for trucks. But in a bundle with low-power motors of the first models of vases a large percentage of power, especially in winter time, leaving viscosity friction in the box. And this caused operational problems with cars in winter, such as the increased flow Fuel, low richness when overclocking and dropping maximum speed.

In addition, the constructive margin of strength at the MCPP car VAZ was very high. Therefore, engine oil If the resource of the box is reduced, it is not so much so that it becomes a critical problem.

With the advent of more advanced oils, this item was removed from the instruction manual. However, the box has not undergone the design changes. Therefore, even now, you can pour motor oils into the box of the VAZ classics. The main thing is to choose more thick lubricants, viscosity not lower than 10W-40. Also, there will be no big mistake if, in the absence of a suitable transmission lubricant to add a small amount of engine oil in the MCPP VAZ.

In the mechanical boxes of modern auto pouring engine oils can not. Loads on the teeth of the seven in them significantly increased compared to cars produced 20-30 years ago. What if main gear In the hypoid box, and even with a significant displacement of the axes - the fill of motor oils in this case is completely prohibited. Case in the absence of sufficient number non-promotional additivesthat will certainly lead to destruction contact surface Teeth transfer of this type.

Once manufacturers produce motor and transmission oils, there is a question of whether the engine oil can be poured into a gearbox. An unambiguous answer "Yes" or "No" to this question is impossible. In one case, it is possible with small negative consequences for gearbox parts. In other situations, it is quite acceptable.

To unambiguously answer this question, it is necessary to study the characteristics of both lubricants and aggregates for which their use is assumed. Also plays the role of the raw material from which they are produced and the presence of additives that improve their properties.

Is it possible to fill the engine oil in the gearbox wants to know many owners of the windows with front-wheel drive, as well as the owners of "Classics". The reason for this interest was the fact that in the first samples of machines with the front-wheel drive, the vase was poured the same lubricant liquid In the engine and gearbox. From that moment, quite a long time has passed, a slightly changed the design of the transmission, developed new varieties of motor and transmission oils. Therefore, only after careful examination of characteristics and compatibility, you can get an answer.

What is the difference between engine oil from transmission?

These two products work in completely different conditions, have different compositions and characteristics. Can be made from mineral raw materials, semi-synthetic materials and fully synthetic. They also differ in quantity and type of additives added to their composition to improve properties. The selection of additives is completely dependent on the conditions in which they work.

Conditions in which motor oils have to work are much harder than for plastic lubricants or transmission fluids. For motor lubricants, the mode of operation can be described as "torn". They are subject to high degree Heating, large amount of temperature and pressure drops. Exposed to chemical reactions from various gases, residues of fuel combustion products, a small amount of gasoline or diesel fuelwhich can get into its composition.

Such complex I. heavy conditions Do not affect lubricants, as they must provide for a long time:

• Serve as a seal between cylinder, pistons and rings;
• To protect the details from the emergence of corrosion;
• Provide heat dissipation from the friction zone.

A little about transmission lubricants

On the choice of such lubricants to the owners to think much less frequently, since the change is made through a significant period of operation of the machine, sometimes it happens in a few years. Transmission lubrication is applied not only in automatic transmission or mechanical boxes. It is poured into bridges, gearbox, steering columns and other mechanisms where gears are there.

The exception is "automata" in which oil acts as a working fluid. In these mechanisms, lubricants should provide:

• Minimal wear between rubbing pairs using the resulting oil film;
• Reduction of losses for friction toothed pairs;
• Serve as a heat transfer for heat out of the friction zone;
• Remove from the cohere of friction, which appeared wear products;
• Eliminate the emergence of corrosion foci in the serviced mechanism;
• Reduce noise from working mechanisms.

Is it possible to replace or not?

Now, when some characteristics and properties of both types of lubricants have become known, you can talk about possible replacements. In fact, all experts recommend in such cases to follow the instructions for operating the machine. Some models of automobiles with front-wheel drive allow short-term use of motor oils in gearboxes, but with a reservation, that the service life of the mechanisms can be reduced by about 30%.

Uniquely "no" can be said for the owners of the "classics", for which even replacement of transmission lubricant TAP on TAP leads to accelerated wear of gearboxes. Sometimes there is enough just a few thousand kilometers of run, and the repair of the box becomes inevitable. If suddenly there is an urgent need for an addler, it is possible, but provided that in the shortest time it is to drain the lubricant and replace the new car manufacturer recommended by the plant.

You can not pour engine oil in robotic boxes or variators. They have high demands on oil viscosity, such as 75W90, so take off to the choice of oil into such aggregates very carefully. Savings on the transmission lubricant can turn into the cost repair of the box. We hope that readers have become clear whether the engine oil can be poured into the box. This is a serious question for those drivers who carefully relate to their car and are ready to use it for a long time.

Before the car owner who changes the cars not every year, sooner or later the question arises about how to choose oil in the gearbox automatic. To consciously decide on the specific composition, you need to understand why it is needed and how the automatic transmission works.

Lubrication not only reduces friction between pairs of parts, but also takes over the heat, cleanses the surface, prevents the formation of corrosion. To ensure the normal performance of all the tasks, the compositions are supplied with additives - special synthetic substances with those or other properties. The quantity and ratio of additives is the main factor determining the applicability of the product to a particular CAT. To make it easier to figure out the drivers, specifications are created - requirements for substances used in boxes.

Before you decide which oil to pour into the box, you need to understand whether it is necessary to do it at all. Regulations replacement ATF. Individual for each car model. It is necessary to be guided by the instruction manual for the machine. Many manufacturers are calculated lubricant For the entire service life of the car. That is, it is assumed that the replacement will be needed only with a serious breakage and overhaul.

When to change?

Motorists and auto mechanics agree that the ATF replacement is necessary. Lubrication is gradually produced, oxidized, loses its properties. Manufacturers recommendations are designed only for the period warranty.

If the checkpoint works normally, there are no knocks, hotels, delays when switching, vibrations, you should not touch the component. When any problems appear, the first thing you need to think is the production of composition.

If the machine is under warranty, it is worth contacting the dealer. Replacing the oil in unauthorized workshops or independent work is a violation of warranty obligations.

How is the replacement?

Under the conditions of a home garage, it is possible to change the oil only in part, 20-40% of the old substance will remain inside. Such a procedure will solve the problems that have arisen, but it is preferable to replace the oil completely. Experts drive out the old fuel from the system using a special high pressure air apparatus.

The procedure for partial replacement:

1. We warm the car by passing 10-15 km.
2. Unscrew drain plug Carter box.
3. Wait until the composition stalks.
4. Pour the fresh substance in the automatic (as much as the old one left).
5. Repeat the procedure 3-5 times every 150-200 km of mileage.

After that, almost all old oil will dilute new.

How to choose a product?

Before replacing work, it is necessary to decide which oil to pour into the machine. The inexperienced motorist is difficult to navigate in the variety of manufacturers and models of fuel.

Many autocontracers produce ATF under their own brand. It is poured in production. So companies of BMW, Toyota, Nissan, Mercedes, Volkswagen Group, Chevrolet, Kia, Hyundai are coming. In the instructions for the operation of the machines, it is indicated which compositions need to be poured into an automatic box.

For each original oil You can choose an analog. Autocontracens will not create lubricants themselves, they simply order their release from large specialized companies and pack in Tar with their brand. Therefore, analogues are often identical to each other. The selection is performed according to the characteristics of fuel and admission.

Buying products better at car dealers. Oils are often faked. Therefore, savings on them will lead to problems with the machine, the development of parts, the need for major repairs.

Basic aTF specification called dexron. It was developed by General Motors and adopted by all manufacturers of the world. Here are the main marks of this standard:

• DEXRON B;
• DEXRON II;
• DEXRON III;
• DEXRON IV;
• DEXRON IV SERVICE FILL.

Each of the specifications put forward certain requirements for kinematic viscosity, Brookfield viscosity at certain temperatures, flash temperatures, flammings, foaming, degree of protection against corrosion formation and other characteristics. If the auto operating manual provides only the required oil parameters, you can choose what to fill in the automatic transmission, by reading in detail the specifications.

Motor formulations and gearboxes

Under the USSR was not big choice Fuel and lubricants. Therefore, machine manufacturers poured into the gearbox and the same compositions. Construction features Cars of those times allowed to do this without having much harm to the car. IN modern world All otherwise. The boxes have become more complex, more details have appeared in them - the loads that they test when interacting with each other will not be able to make a conventional product for motors.

The main element of the gearbox is the gear. There are two types of clutch of these parts among themselves:

1. The hypoid - teeth are in contact point.
2. Still-fixed - when two gear teeth are connected, they move together until the end of the trip. In other words, remain fixed relative to each other. Because of this, additional sliding loads arise. At this point, the oil film "moves" from the surface.

To ensure normal lubrication in ATF add firming additives. In addition, the machine is a closed, almost hermetic system. Therefore, when working there are high temperatures. The usual engine oil, even with the highest SAE index, will become too fluid, will not be able to perform its functions.

On the question of whether it is possible to pour engine oil into the gearbox modern car, the answer is unequivocal - no. This will lead to a very serious breakage. Details work out for several tens of thousands of kilometers, that is, over the year - two not too active operation of the machine. If we are talking about old domestic autoThis experiment can be carried out after a thorough study of the operating manual.
