Owners are often faced with the need to mix oils and technical fluids... As a rule, difficulties arise in the process of replacing or refilling both engine and transmission oils.

As for the transmission, motorists in some cases are interested in whether it is possible to fill engine oil in a box, bridges, gearboxes, etc. This is due to the fact that modern engine oils are designed for heavy loads, and also contain extended packages of active chemical additives to work in the most difficult conditions... Let's figure it out.

Engine oil in manual transmission

Immediately, we note that if we are talking about (or), in this case, it is better to immediately abandon attempts to fill in engine oil, even in the event of a critical decrease in the fluid level in the transmission during various malfunctions.

The fact is that such a box may fail or work incorrectly even on special aTF fluids, which are not recommended by the manufacturer for a particular type of automatic transmission or CVT.

The choice of oil for a manual transmission: types of transmission oils, features and differences. What kind of oil is better to fill in the manual transmission, what needs to be considered.

Each transmission has gears mounted on shafts. They are rotated by bearings, which, along with the meshing gears, require regular lubrication. The choice of oil is necessary taking into account the operating conditions for rubbing pairs. And here the question arises, which oil is better in a VAZ gearbox? For most motorists, it is no secret that helical cylindrical gears are used in the boxes, in which two gears are in contact with each other with teeth. This contact has a plane-motionless character, that is, when two teeth mesh, they become motionless relative to each other.

This is the main difference between them from hypoid transmissions, in which the contact is point. Due to certain design features they have longitudinal sliding of the teeth, which causes strong contact stresses and significantly worsens the lubricating conditions.

Oils for hypoid gearboxes

Serious unit pressures and significant longitudinal sliding cause the destruction of the oil film in the contact zone, and this can contribute to the seizure of the metal of the rubbing surfaces. This disadvantage of hypoid gearboxes is usually eliminated by using high viscosity oils with special additives, which provide sufficient strength of the oil film. Also, the gears receive additional phosphating.

Classification of oils

According to the international system API transmission oils are divided into several categories:

1. GL-1 - SAE 75W. These oils are suitable for spur, worm and bevel gears operating at pressures up to 1600 MPa and temperatures no more than 90 degrees.
2. GL-2 - SAE 80W / 85W. Suitable for spur and spiral bevel gears. They work with pressures up to 2100 MPa and at temperatures up to 120 degrees.
3. GL-3 - SAE 90 - similar to the previous one, but withstands up to 2500 MPa and up to 120 degrees.
4. GL-4 - SAE 140. Designed for various transmissions, including hypoid transmissions with operating pressures up to 3000 MPa and temperatures up to 150 degrees.
5. GL-5 - SAE 250. Designed for hypoid gear with pressure over 3000 MPa and temperature over 180 degrees.
6. GL-6 - Applicable with hypoid gears operating in harsh operating conditions. The oil contains particularly effective antiwear and extreme pressure additives.

The oil designed for VAZ oil is suitable for front-wheel drive cars. Typically, such boxes are filled with GL-3 or GL-4 greases.

Engine oil in a box VAZ

Some car owners do not understand where the recommendation for pouring engine oils into the transmission of VAZ cars came from. The fact is that engine oils are operational characteristics refer to GL-1 or GL-2. When the automaker began to produce the first front-wheel drive VAZ 2108 in 1984, the USSR did not have a sufficient volume of suitable oils that would satisfy the required properties. Most popular for passenger cars then there were motor M5z, M6z, M8z, as well as the transmission TAD-17, which was later replaced by the TAD-17I. The last two meet the requirements of the GL-5 group.

Consequently, motorists chose the lesser of two evils. Too viscous oil in larger boxes caused high loads acting on the synchronizers and causing significant mechanical losses in frost.

First fill oils

Gradually, new types of oils appeared, including imported ones, and the recommendations of car manufacturers changed. The plant itself began to introduce oil into a box of vases for the first bay of TM 5-9P in the assembly production.

This oil is poured only at the factory, and it does not go on sale. According to the recommendations of the automaker, this lubricant in front-wheel drive gearboxes must be changed after 75 thousand kilometers. On classic and all-wheel drive VAZs, this oil is changed after running-in, that is, after 2-3 thousand kilometers.

Oils for VAZ 08-099 boxes of the following brands are on sale:

• TSp-10 (TM-3-9),
• TSp-15k (TM-3-18),
• Tap-15v (TM-3-18),
• TSz-9gip (TM-4-9z),
• "Rexol T" SAE 80W-85 API GL-4,
• "Volnez TM 5-12".

As for imported transmission fluids, almost any lubricant that meets the GL-3 and GL-4 classifications can be used.

Viscosity selection

The use of domestic gear oils for VAZ, many of which today belong to aPI class GL-5 contributes to accelerated wear of synchronizers. In this regard, in the transmission of front-wheel drive cars, it is better to fill in API GL-4 or API GL-4/5 fluids with a viscosity:

• SAE 75W-80,
• SAE 80W-85,
• SAE 80W-90.

Domestic GL-4 oil is not easy to find and is often expensive semisynthetics or synthetics. It is better to buy imported fluids, the use of which helps to extend the life of the vehicle's transmission. How to change the oil in the VAZ gearbox, read in a separate article on our website.

There is no need to pour oil into the high-viscosity VAZ gearbox, including motor 5W-50 and 10W-50, as well as transmission 85W-90. The higher the viscosity, the more durable the oil film is and the thinner the oil penetrates to the elements of the box. Too high a viscosity makes it difficult for the synchronizers to work as excess oil must be squeezed out. The car manufacturer VAZ recommends TM-4-12 fluid with a viscosity of SAE 80W-85. The main thing is to find the original on sale, not a fake.

Today, about 95% of all transmission oils available on the car market are made up of multigrade components. In addition, in order to know the VAZ 2110, you need to understand the numerous brands and manufacturers, which greatly complicates the choice of a motorist. In any car store, the owner of a VAZ 2110 can find at least two dozen types of oils that are suitable for his car. But not every car enthusiast knows what nuances need to be considered when buying a fluid.

What is the best oil to use?

The main buying factor transmission fluid - this is not the choice of the manufacturer, but the selection of the original liquid directly. The market is teeming with fakes, so the choice of oil (MTF) must be approached with utmost care, since counterfeit products can only harm the VAZ 2110 gearbox. For starters - forget about questionable stalls and car markets - buy MTF in strictly specialized stores, so that if something happens it was possible to make a claim.

Next, consider which MTF is better to pour into the gearbox (gearbox) according to viscosity properties and working temperature... It is recommended to select oil for the box of your "iron horse" based solely on climatic conditions and the time of year your car is currently in use.

Draining the oil from the box VAZ 2110

The main factor for replacing the transmission is the deterioration of its working properties during operation. From the instructions from the manufacturer it follows that the replacement is carried out every 30 thousand km. In addition, when using a poor-quality product, there is a possibility of noise in the box or an unpleasant sound when changing gears.

Now let's talk about which MTF is better to cast in - synthetic, mineral or semi-synthetic. It has long been known that "semi-synthetics" work much more efficiently than "mineral water" and "synthetics". "Semi-synthetics" is a compromise solution, since its working properties are better than that of mineral ones, and it is cheaper than synthetics. Also, such a liquid is more suitable for using a car in a temperate climate:

• the main advantage of "semi-synthetics" is its high lubricating properties;
• wider operating temperature range.

GL-4 is suitable for gearboxes of VAZ cars with front-wheel drive, in particular for model 2110.

What tools do you need to prepare?

Before proceeding with the direct replacement of MTF in the VAZ 2110 gearbox, you should prepare everything that you may need. This must be done in advance so that at any time you have everything you need at hand. So, you will need:

• set of wrenches;
• bottom inspection lamp;
• container - plastic or metal (used oil will be drained into it);
• rubber gloves (hands in oil are very difficult to wash);
• canister 5 liters;
• rags or newspaper.

And, of course, the liquid itself. Having prepared all this, you can begin to replace it.

Step-by-step instructions for replacing

Due to the location of the MTF drain hole in the checkpoint, its replacement is possible only on a pit or on an overpass. Be careful when draining the oil as the temperature is very high and it can cause burns if it gets on your skin.

1. If you change the fluid in the gearbox, then first of all, you should warm up the car to allow the thickened oil to take on a more liquid state, since all the fluid will not leak out of the cold box.
2. Next, we drive into a pit or overpass, wait 5-10 minutes for the box to cool down a little.
3. We place a container under the hole for draining the liquid and using a wrench, carefully unscrew the nut to drain the MTF.
4. If the waste fluid contains metal dust and other dirt, the gearbox will have to be flushed. To do this, you need to raise the front wheels, and then pour a special flushing fluid and start the car. We turn on the first gear and let the car run for 2-3 minutes.
5. Then we turn off the car, lower the front wheels and carefully drain the flushing fluid according to the same scheme (p. 1 - 3).
6. Changing the oil in the box is a laborious process. You should wait a while for the filled mixture to drain out of the box completely.
7. We take the purchased MTF and start pouring it into your checkpoint in the required amount and check the level. If everything is in order, you need to make a short trip and check the level again, if necessary top up. When checking the level, the car must be strictly horizontal.

As you can see, the process of replacing the gearbox fluid is not so difficult. Correctly performing all actions, even an inexperienced driver can cope with this.

Important to remember! With correct and timely replacement oil in the gearbox, you ensure trouble-free and long-term operation of your car.

What kind of oil do you fill in the gearbox of your car? Maybe you have your own technology to replace it? Share your knowledge with our readers!

Sooner or later, or rather, according to the regulations maintenance it is time to change the lubricant in the gearbox for the VAZ-2114. And then the owner is faced with a difficult choice, which oil is best?

The choice of oil in the gearbox on the VAZ-2114

There is old oil in the bottle, drained from the gearbox on the VAZ-2114 with a mileage of 55,000 km

If we consider the choice of oil for the VAZ-2114 gearbox, then of course, the manufacturer provides in the technical documentation a recommended set of lubricating fluids for all components and assemblies. Only now it does not always correspond to the realities of quality and use by motorists.

Having considered many sources of information, as well as automotive forums, we can come to the conclusion that motorists pour the oil they like into the gearbox. Here they are doing the wrong thing, because the high-quality functioning of the node, as well as its resource, depends on this element.

We will not walk around for a long time, and around and consider which oils are the most popular among motorists, as well as recommended for use:

1. 75w-90 – synthetic oilrecommended by the manufacturer. This type is used in all modern AvtoVAZ transmissions. Excellent lubricating characteristics must ensure the functioning of the unit at high and low temperatures... Increased noise during operation of the gearbox compared to semi-synthetic oil. According to API classification, GL-4 standard.
2. 85w-90 – semi-synthetic oil, API class is also not lower than GL-4. Recommended for used cars. It costs less than "synthetics", and the checkpoint works on it quieter.

It's all general characteristics, but many car enthusiasts will ask the question: what specific manufacturers can be poured into the gearbox? So, we will consider this issue in more detail and write a list of transmission oils that can and should be poured into this unit:

• Lada Trans KP;
• Lukoil TM 4-12;
• New Trans KP;
• Nordix Supertrans RHS;
• Slavneft TM-4.
• Castrol 75w90;
• Shell Getribeoil EP 75w90;
• TNK 75w90.

The last three are more expensive specimens, but surpass their budget counterparts in their composition and chemical properties.

Therefore, if a motorist loves and cares for his "iron horse", then of course he will choose them.

Types of oils

As you know, the labeling of oils was invented for a reason. There are three types of oil that are filled into the engine and transmission. They all have different indicators, but the main one is considered to be viscosity. So, let's look at how automotive lubricating fluids are classified: Conclusions

As you can see from the article, the choice of oil for the VAZ-2114 is quite simple. There is a list of recommended oils from which to choose the most suitable option for the motorist.

Whoever chooses quality, despite the price, it is recommended to fill in Castrol 75w90, but Lada Trans KP is considered a budget option.

Tell me, please, but the opinions differ from sales consultants in stores and from my friends, motorists.
The question is: "what kind of oil is better to fill in the perdach box in the VAZ 2110 (in my case, -21102) - mineral, semi-synthetic or synthetic" The fact is that there are opinions that synthetics corrode our, domestic, oil seals. Your opinions or based on experience - tell me. I want to replace the oil. Just the first time.

Does not corrode, but seeps into the cracks

I have a different approach, a little outdated probably. Applies to oil in the gearbox.
Liquid for the city, thick for the highway. At the very 21103, xs th there is flooded at the factory.

Doggy Le-a-zu

GL-4 B groups only front-wheel drive, and the viscosity is certainly the best 75W90 is synthenics 250-350 rubles a liter. It is liquid in winter and maintains a stable viscosity when heated.

Castrol TAF-X, GL-4. Synthetics, excellent oil. About leaking oil seals, complete nonsense. For five years it is flooded and does not flow from anywhere. Excellent work of the gearbox even in very severe frosts, the gears change smoothly, without jamming. Long service life, I will change no earlier than 100-120 t.km. What else is needed? What was flooded at the plant was leaked immediately.

About leaks of oil seals RAVEN MALE. and most sellers do not fumble about anything at all. Lei everywhere expensive synthetics and you will be glad -)

Yes, xs, at the expense of expensive synthetics they wrote in at the wheel, such as intended for other checkpoints, the enemies say they have different standards. In short, there was 1 place given to Lukoil, then like castrol, but then the question is to believe their tests or not. I changed my cheeks (VAZ 2112) and advised me to change the gearbox oil, and advised just lukoil ... see there are 4 and 5 current, you need 4 in no case do not mix it up !!!

"I apologize in advance, I just don't want to create a topic," but on a VAZ 2104 which is better to pour oil into the checkpoint, only for more details please, otherwise I did not change it

If I remember correctly the manual for the nine, it is generally necessary to pour engine oil there.

Classic box and bridge lei 80w90
the bridge hd 80w90
in a box GX 80w90
you can, of course, take a larger viscosity 85w140, but in winter the frozen "Kazinak" will not be turned by any forces.

actually, for hypoid gears, which are gearboxes, the GL-5 group was created

The vast majority of boxes do not have a hypoid main pair. Conventional helical gearing. Therefore, GL-4 is the very thing. Lifetime tests of GL-5 in front-wheel drive gearboxes of VAZ did not show increased wear of synchronizers.
Engine oil was poured into the checkpoint back in those shaggy years when there was nothing else. Now this is a perversion of the unit.

tarland, I have in my hands the "instruction" of the 1993 edition
