What kind of oil to pour into the VAZ-2109 box

One of the most sensitive questions. Most owners of this car model can sit on forums for days and search for information on this matter. But, as they say, everything ingenious is simple, and this is exactly the case. It’s enough to open the instruction manual, where, in fact, everything is written, but if you don’t have one, then here are some useful tips. So, in our gearbox the main pair of teeth is helical, and not hypoid, as on the “classic”, so we can say right away that it makes no sense to fill such a gearbox with TAD-17I oil. As for using engine oil in the gearbox, this is a more suitable method, but it is especially applicable to “nines” manufactured before 1993. After 1993, TM 5-9M oil is used. In models with front-wheel drive, it can operate for 70-75 thousand kilometers. However, this brand of oil is not available for sale.

Features of VAZ gearboxes

With the advent of cars of the “eighth” and “ninth” families in the 80s, many car owners were perplexed by the fact that motor oil could be poured into the transmission of these models.


Such originality was caused by a fundamentally new design of the gearbox, which worked exclusively on special fluids. But since quite a few such oils were produced in the USSR, ordinary motor substances were poured into the gearbox.

Which gearbox oil for a VAZ 2109 should I choose at a car store?

And so we came to the auto store to buy oil in a box for the VAZ-2109. Of course, sellers today are more likely to sell you a more expensive product. However, it is best to give preference to imported oils in the mid-price range. But here we are faced with classification. GL-4 is an oil that is used for “nines” with front-wheel drive. GL-5 is used in other cases. You can also find combined oils of the GL-4/5 brand; they are suitable for all VAZ-2109. The oil box must be filled with GL-4 or GL-4/5, the viscosity should be as follows: 75w-40, 80W-90. It won’t be difficult to find all this in specialized stores. However, extremely seductive low prices should be avoided. The average temperature range varies from -25 to +40 degrees Celsius. As a rule, the lower the thickening temperature, the better, especially given the harsh winters in our region.

Popular oil TAD-17I

TAD-17

A common brand of transmission oil for the VAZ 2109, TAD-17I, was created for spur, hypoid and helical, highly loaded gears that operated with contact loads between the teeth of more than 3,000 MPa, but it was not suitable for VAZ 2109 transmissions.

The high viscosity of the lubricant and special additives in the composition, which make the oil film more durable, contributed to the abundant lubrication of the synchronizers, but the oil was not completely squeezed out. Because of this, the angular velocity of the gears and sliding clutch was not equalized, and the gears were engaged with difficulty and with an extraneous sound. At the same time, accelerated wear of the transmission occurred.

How much oil to put in the box

3 liters

This can be established experimentally, but you can spoil a certain amount of oil, which, by the way, is not cheap. If the box is completely empty, then it contains smoothly 3 liters. But again, this takes into account the fact that the old oil was drained entirely. It should be noted that there is a special dipstick that can be used to check the oil level. To do this, you need to take out the dipstick, it is located near the battery in the engine compartment, and wipe it with a clean rag. After this, it is inserted all the way and taken out again. If the degree is between the maximum and minimum marks, then everything is in order, if it is higher or lower, then you need to either drain or add oil. There are some nuances regarding filling volumes. In particular, it all depends on how many degrees the checkpoint has. If it is a four-speed gearbox, then fill in 3.1 liters, if it is a five-speed gearbox, then fill in 3.3 liters. A lot of detailed information specifically about your case can be found in the service book.

Direct replacement (manual transmission with a dipstick)

  1. Replacement is carried out with the box heated to operating temperature (so that the maximum amount of waste and wear products drains out).
  2. Using a rag and thin wire, clean the breather and rubber cap (after cleaning, return the cap to its place).
  3. We unscrew the drain plug and drain the waste liquid into a specially prepared container, then return the plug back.
  4. We take out the dipstick and pour transmission fluid through the hole (using a funnel), wipe the dipstick with a rag and install it in place.
  5. We wait five minutes and then take out the dipstick and measure the oil level, adding it if necessary.

During operation, we check the fluid level every 10 - 15 thousand kilometers in order to avoid transmission breakdowns due to low oil level. If the gearbox consumes a lot of oil, it should be replaced as often as possible.

  1. On VAZ 2109 (21099) cars of earlier versions, the dipstick was not installed; if you have such a car, the replacement process is carried out slightly differently.
  2. The oil fill hole is located on the right side of the gearbox housing.
  3. We remove the plug, take a syringe and, using it, pour oil into the box.
  4. To avoid overfilling transmission fluid, focus on the lower edge of the oil filler hole.

It is recommended to carry out this process with a warm engine, since liquid oil drains better from various components and parts of the car. If the replacement is carried out in winter, then it is advisable to drive the car for at least 10 minutes.

Then the car is placed on a pit in the garage (overpass), after which you need to climb under the car and unscrew the filler hole to provide air access. You can also lift the car with a jack, but the side of the car opposite the hole should be higher.

A container is first placed under the drain hole and the drain plug is completely unscrewed. Approximately 3 liters of liquid should pour out. You can tighten the plug if the liquid begins to flow in a thin stream or stops flowing altogether.

A little more useful information

We have already decided what kind of oil to pour into the VAZ-2109 gearbox and how much is needed. Now I would like to say a few words about what high-quality gear oil should be like. Since lubrication in a gearbox is extremely important and work is simply impossible without it, you need to use only a high-quality product that has already proven itself on the market. Synthetic-based oils are more preferable for severe winters, when the temperature drops to -30 at night. Synthetics do not thicken as much, which allows you to start the car the first time even under such conditions. Mineral oils are a little expensive, but do not perform well in sub-zero temperatures. A significant point is the number of additives. In most cases, these are sulfur compounds, which reduce the likelihood of gear scuffing. This type of connection completely eliminates metal scuffing, forming a film that simply wears out during operation. But there are some disadvantages here - the metal literally corrodes, but this still minimizes wear. The conclusion follows that the VAZ-2109 gearbox, for which the oil is purchased wisely, will serve for a long time and properly.

Any unit with moving parts requires lubrication. And in the case of a variable gearbox, the lubricant must also be of proper quality. Which oil is better to buy for the transmission of a VAZ 2109? Light on this issue is shed by these instructions for choosing oil for a VAZ 2109 gearbox. Study this article carefully - here you can learn about the choice between motor and transmission oil, synthetic and semi-synthetic, as well as the choice between different manufacturers of transmission oils.

Transmission oil

There are a great number of such oils and there is not enough time and patience to consider all specific oils. Therefore, we will consider only categories of oils, and in some cases we will give examples. Go:

  • Let us mention the TAD-17 in a little more detail. If anyone doubts that it cannot be used in the VAZ 2109, read below for the reasons for this.


Extremely undesirable oil for the VAZ 2109 gearbox

  • The viscosity or thickness of TAD-17 oil is very high, which leads to the following problems: the car will not start in winter; extreme pressure additives (which in themselves give a good effect) are contained in very large quantities in the oil.
  • A large amount of extreme pressure additives contributes to intensive wear of synchronizers.
  • Synthetic oil would seem to be better suited than the others. It is better in thickness, has positive qualities, and has additives. But there is one thing! The use of synthetic gear oil (designated GL-5 or TM-5) is encouraged in sports gearboxes, where the quality of the parts is better, the temperature range is higher, and (in some cases) there are no synchronizers.

By the way! By carefully reading the instructions for the transmission oil, you can determine whether it is suitable for your car or not.

  • So, in the instructions for GL-5 class synthetic oil it is directly written: “used for unsynchronized manual transmissions.”
  • And one more point not in favor of synthetics is its price. The cost of such oil is high, and practicality is not very good - therefore, the use of synthetic oil in VAZ 2109 gearboxes has no reason.
  • And the last option is semi-synthetic gear oil. It is perfectly suited for use in this car.
  • The designation of this oil is GL-4.

By the way! The service book for the car indicates the type of oil recommended by the manufacturer. This is exactly GL-4 or TM-4.

  • In terms of density, it is better to use the designation 75 or 85. The composition of this oil and its properties are optimal for both gearbox gears and its synchronizers.
  • As for the winter period, semi-synthetics will not freeze as much as mineral water, for example. In frosty temperatures of -25 degrees, the car will start, just like in summer.

Domestic manufacturers

So:

  • The gearbox oil declared by the plant is TM-4-12. Ideally, you should use it, of course. This oil was specially developed for the gearbox of this particular vehicle.
  • Using logic, we come to the conclusion that since it was specially developed, it must be the best. The manufacturer may be different - for example, Rexol.
  • For example, the M6z12G1 engine oil used in the VAZ 2109 gearbox falls slightly short of the TM indicators.
  • LukOil SAE 15W-40 is also a good competitor to specially developed oil, TM-4-12. The gap from it is only 4%.

Foreign manufacturers

We analyze the oil for the VAZ 2109 gearbox of foreign production:

  • The Castrol brand, and more specifically EP-80 and EP-90 oil, which according to the GL-4 class is undesirable for use in Samara gearboxes. Its properties are more suitable for sports gearboxes.
  • But the foreign company Valvoline, which produced DuraBlend SAE 75W-90 oil, showed good performance for our car. This semi-synthetic oil is at the second point, after the recommended domestic oil TM-4-12.
  • On the other hand, the same Valvoline, but no longer GL-4, and GL-4/5 is not suitable for high-quality work on the VAZ 2109 gearbox.

We remember that the presence of extreme pressure additives has a positive effect on the overall performance of the gearbox. However, too much of them contributes to rapid corrosion of metals. All this is because extreme pressure additives introduce sulfur into their composition, which corrodes gears.

  • From this point of view, motor oils are the best contenders (but we also remember their other qualities).
  • And again, semi-synthetic Valvoline turns out to be close to the standard - TM-4-12. And synthetic, on the other hand, turns out to be the most destructive in this regard.

As for other manufacturers, it is worth paying attention to certain points and studying the composition of the oil in detail. Pay attention to:

  • Viscosity
  • Temperature order of oil operation - pour point
  • Number of additives and their type
  • Reviews of other drivers on this oil.

For example, according to reviews from VAZ 2109 owners, the following have good qualities:

  • TNK semi-synthetics
  • ZIC 75W85 G-FF GL-4


Gearbox oil for VAZ 2109

  • Mannol semi-synthetic

Separate tips for filling oil:

  • Although the stated characteristics of the VAZ 2109 car indicate that the amount of oil in the box is 3 liters, it is necessary to fill in a little more.
  • For a 4-speed gearbox you need to fill in 3.3 liters, and for a 5-speed gearbox all 3.5 or even 3.6. This is done so that driving in fifth gear does not strain the car so much.
  • A very interesting point is the use of special XADO miracle additives, which are supposedly capable of ridding the gearbox of whining. Observing the reviews of 2109 drivers, you can notice some features.
  • XADO additives do not give the desired effect, and at the same time they have an exorbitant price. It will be much cheaper to repair the gearbox yourself or at a service station with replacement of failed parts.
  • Check the oil level in the gearbox regularly so that it serves you longer and change the oil on time (70-75 thousand km or earlier if necessary).

VAZ 2109 cars are known for their frequent breakdowns, but parts and repairs are relatively inexpensive. Proper operation and maintenance helps keep your car in good condition. And this is especially true for the gearbox and its high-quality lubrication. What kind of oil to put in the box of a VAZ 2109 is a simple problem, but not everyone knows the answer. Therefore, in this article we will try to respond to it.

Which oil is better?


When choosing a lubricant product for the VAZ 2109 gearbox, you can use the car’s operating manual.
Or you can use the experience of numerous “Nine” owners. The manufacturer AvtoVAZ recommends using mineral all-season lubricants such as:

  • "Rexol T" SAE 80W-85 class GL-4;
  • "Omskoil Trans P" SAE 80W-85 universal classification GL-4/5;
  • "Volnez TM4" SAE 80W-90 class GL-4.

You can also choose a lubricant from other domestic or imported manufacturers. The most important criterion when choosing should be the class of the lubricant.

Since the VAZ 2109 is a front-wheel drive car, it is worth filling in oils of class GL-3 and GL-4 according to the foreign classification or TM-3 and TM-4 according to the domestic one. It is worth remembering that it is impossible to fill a product of class GL-5TM-5. This can negatively affect the gearbox synchronizers.

Conclusion

What can you briefly say about the choice of oil for the VAZ 2109 transmission? The use of motor oil in modern cars is undesirable. In addition, it preserves the synchronizers, but corrodes the gears. Using a special gear oil developed for the VAZ 2109 - TM-4-12 - is the best option. Using other gear oils is quite possible, but the choice must be made wisely. Transmission oil should be taken only of class GL-4 or TM-4 and a viscosity of approximately 75W-90. You should choose the manufacturer for yourself - based on your budget, but not forgetting what is written a little higher. But the bottom line is this: there is simply no ideal oil, such that a car will run on it forever! The engine ruins the gears, the transmission ruins the synchronizers. And yet the special oil TM-4-12 remains the best. When choosing it, the main thing is not to fall for a counterfeit product! Happy shopping and may your VAZ 2109 drive for a long time and not break down!

Instructions

The VAZ 2109 was produced from 1987 to 2011 and therefore these cars have some differences in the design of the gearbox, namely: a manual gearbox can be with or without a dipstick. In this regard, replacing a lubricant has its own characteristics. The replacement should be made on a warm car, that is, after a trip. This will help it drain quickly.

For the basis of the operation itself, the transport must be placed on a lift or inspection pit. If the car is on a flat, horizontal surface, this will help you find out the exact degree of the substance poured into the transmission. A special feature is that in boxes with a dipstick (many new models), the filler hole or the dipstick itself is located on top. You can get to the points where you pour the substance through the open hood.

And many early models do not have a dipstick, but instead there is a filler hole covered with a filler plug. It is accessed from the lower part of the car. Using a syringe, filling in lubricant in both cases is quite simple. So, let's begin the process of replacing the lubricant in the VAZ 2109 car.

Indication of the drain hole Indication of the breather Indication of the drain hole if there is a dipstick Oil on the dipstick marks Drain and fill hole Funnel in the fill hole Filling oil with a syringe

Step 1 - Test the oil level

Without a dipstick, the lubricant level can be checked by supporting your finger or visually. To do this we do the following:

  1. Under the car, in the front lobe, unscrew the transmission filler plug.
  2. If the liquid begins to flow out, then the liquid level is sufficient. If not, check with your finger. The optimal amount of liquid should reach the level of the edge of the filler hole.
  3. You can also check the current degree of lubrication after pouring it into a container. This will show how much substance was in the aggregate.

In many modern models, a dipstick is installed instead of a filler plug. Using it, checking the lubricant number is relatively simple:

  1. Unscrew the dipstick plug.
  2. Wipe off any remaining oil. This is done because previously the substance could have reached above the current level while the car was moving.
  3. We place the clean probe in a “quiet” box.
  4. We take it out and determine how much lubricant is at this moment. In the case when the liquid touches the lower mark (MIN) - the minimum allowed level. The optimal oil level is if it has colored the dipstick to the upper rating (MAX).

Step 2 - Drain the oil

  1. First of all, remove the rubber plug from the breather, then clean the breather while supporting the wire and close it with the plug again. With this action you equalize the internal pressure in the gearbox.
  2. Further, unscrew the bolted drain plug. In both cases, it can be found at the bottom of the gearbox.
  3. Drain the liquid into a previously prepared container. On a “hot” car, the liquid drains faster, but in general it will take several minutes.
  4. After the liquid is drained, the drain hole closes.

Step 3 - Oil Change

In VAZ 2109 cars, the filler hole, like the drain hole, is located at the bottom. To replace we do the following:

  1. We unscrew the drain plug.
  2. Using a syringe, fill the gearbox with lubricant. We stop the procedure when the liquid reaches the edge of the hole.
  3. Close the filler plug.

It is worth noting that for 5-speed transmissions it is worth pouring 300–350 ml more lubricant than normal. Otherwise, when the box is operating in 5th gear, it may “cry” about the lack of fluid, even if it is filled to the brim.

To do this you need:

  1. Raise the side of the car opposite the filler hole with a jack (or any other accessible or convenient way). This will prevent additional fluid from leaking out.
  2. While raised, add additional lubricant.
  3. Close the filler hole with a plug and return the car to a horizontal position.

In order to change the oil in a VAZ 2109 through the dipstick hole, we perform the following procedures:

  1. We find the hood.
  2. We take out the dipstick plug.
  3. Using a funnel or syringe, pour lubricating fluid into the cold hole.
  4. When pouring the substance, you should check the current level while supporting the dipstick. When the level reaches the MAX mark, we stop the filling process.
  5. Close the dipstick plug.

The oil change in the VAZ 2109 gearbox has been completed. Now the gearbox in your car will last longer and will not bother you with faulty operation.

Preparation for work

The first thing you need to know is that the oil change in the VAZ gearbox of the ninth model is carried out after this unit has warmed up. If you decide to have surgery immediately after your trip, then this is an ideal option. Otherwise, you will have to leave the garage and drive several kilometers, since the unit will not warm up at idle engine speed if the car is stationary, for obvious reasons. An inspection ditch or overpass will be required; without it, it will be extremely difficult to complete the work. Here is a list of tools and materials that will be needed during replacement.

  1. Wrench size 17 mm, open-end or socket head.
  2. Drain pan for waste.
  3. A fill funnel, to the neck of which you need to securely attach a hose or tube about half a meter long.
  4. Lighting device (flashlight or portable lamp).
  5. A rag for removing oil spills.

After the machine is installed on an inspection ditch or overpass and secured with a hand brake, it is recommended to remove the oil pan protection. Perhaps many will consider this extra work, since the protection has a special opening for access to the neck. But when flowing out of the crankcase, the stream of oil partially enters it, and the other part spreads over the inner surface of the protection and begins to drip from all sides. All this will have to be wiped off, and the oil remaining on the protective casing will subsequently attract dust and dirt.

Useful tips for choosing gearbox oil for a VAZ 2109

Changing the gearbox oil is a significant part of car maintenance for any car. Over time, the lubricant ages and ceases to perform its functions, thereby causing wear of structural parts. The VAZ Nine gearbox is reliable and durable, but it cannot do without maintenance. The replacement procedure is simple; a motorist can handle this task on his own. Before pouring oil into the VAZ-2109 box, it is important to familiarize yourself with the automaker’s recommendations.

About types of transmission oils

For VAZ 2109 vehicles, it is recommended to use the following types of gear oils:

  1. API GL-4
  2. SAE

Let's talk about each of these types in more detail.

API GL-4

These gear oils are suitable for use in a variety of conditions from light to heavy and are used in synchronized gearboxes.

SAE

The most popular classification of transmission oils. The following types are suitable for the VAZ 2109 box:

  1. Mineral 85 W This type of oil is perfect for gearboxes with high mileage. It has good lubricating properties in hot weather due to its good viscosity and thickens at low temperatures.
  2. Semi-synthetic 75 W Lubricating properties at a high level. In warm climates it remains quite viscous. In winter it warms up quickly. Reduces noise during gearbox operation
  3. Synthetics 75 W In summer, due to high temperatures, it becomes liquid. Particular attention should be paid to the gearbox seals; oil leaks are likely; it does not thicken in the cold.

Author's advice: When choosing gear oil for a VAZ 2109 gearbox, you should take into account your financial capabilities and the recommendations of specialists.

Replacement frequency

Despite the durability of the gearbox, it also tends to wear out and periodically requires attention from the car owner. A scheduled oil change in the VAZ-2109 gearbox should be carried out every 70 thousand km. mileage or after 5 years of operation. However, if extraneous sounds begin to appear from the structure, the procedure must be carried out earlier. It is also necessary to take into account the fact in what conditions the vehicle is operated. Sometimes the replacement time is almost halved, for example, for cars subjected to heavy loads, the service interval will be about 40 thousand kilometers.

Testing the volume and condition of the oil

Every 5 - 10 thousand km. It is recommended to test the level, condition of the oil, as well as the box for leaks. Continuous monitoring allows you to protect parts from wear and tear, preventing the need for repairs in a timely manner. The vehicle must be placed on a flat surface during the procedure.

You can check the oil level in the VAZ-2109 gearbox using a dipstick located under the hood. To do this, pull out the device, wipe off the grease and push it back in until it stops, then take it out again and evaluate the results.

Ideally, the oil level is at the upper mark of the meter, but if not, then it is necessary to add fluid to the desired level, and it is important not to overfill the lubricant more than required. The lower mark of the device shows the minimum permissible value, and if it is lowered, there is already a danger of early failure of the box.

In addition, it is important to monitor the condition of the liquid. Its color, which tends to change over time and is often far from the original, will say a lot. If the oil remains transparent but has darkened a little, then this is considered normal, but if it becomes cloudy and looks dirty, it means that a large amount of metal shavings and other deposits have accumulated in it. It is also important to pay attention to the presence of a burning smell. In this case, the box urgently needs to replace the lubricant.

How to change transmission oil on a “nine”?

We have already found out what kind of oil to pour into the VAZ 2109 box, now let’s talk about how to replace it correctly. Let us note right away that this will take you no more than 15-20 minutes of free time, so there is simply no point in going to the service station.

So, first, let's prepare the tools. During the work, we will need 10 and 17 mm wrenches, as well as a container for waste fluid. The latter can be made from an empty can of antifreeze or machine oil - just cut out one side of it with a knife.

Let's get to work. First, you need to use a 10 mm wrench to unscrew the engine protection fasteners. They are located under the front bumper. Next, using a screwdriver, unscrew the 2 bolts of the protection, which is located closer to the interior.

Now we place our “modernized” canister under the car in a horizontal position and, using a 17 mm wrench, unscrew the drain plug. Please note that this part is under pressure and together with the liquid it may fall into the canister.

We wait until the old transmission oil drains out and screw the plug back on. Next, we put the engine protection in place and take the oil dipstick from the gearbox. The latter is located at the top of the checkpoint. To find out the oil level, you need to wipe the dipstick with a dry cloth, reinstall it and pull it out again after 2-3 seconds. In this case, the car should not be on a slope. Ideally, there should not be a drop of oil on the dipstick. If this is the case, then you can safely fill the gearbox with new fluid.

Oil options for the VAZ-2109 gearbox

The fact that the performance of the transmission depends on the quality of the lubricant being poured is no longer a secret, but a well-known fact. An ill-chosen product can affect the functioning of the device and lead to very undesirable consequences. The Nine gearbox does not require the purchase of extremely expensive oil, but its technical characteristics still play a significant role in ensuring stable operation. There are certain recommendations for selecting a lubricant suitable for this vehicle. The choice should be taken with full responsibility, because the serviceability, service life of the structure, as well as the frequency of replacement will depend on what kind of oil is poured into the VAZ-2109 box.

Let's look at the factory recommendations

When selecting transmission fluid, it is better to adhere to the car manufacturer's recommendations. This ensures the compatibility of the product with the box and ensures the stability of the device.

The manufacturer recommends using all-season mineral oils of domestic brands with viscosity characteristics 80W-85, 80W-90:

  • Omskoil Trans P class GL-4/5;
  • Rexol T GL-4;
  • Volnese TM4 GL-4.

The plant poured mineral lubricant from Lukoil into the cars, but in practice, in winter, the liquid is not adapted to cope with very low temperatures.

The range of compounds for the Nine transmission is quite wide and is not limited to a few brands. The manufacturer recommends for use oil of classifications GL-3 and GL-4, as well as TM-3 and TM-4 according to Russian standards. You can bend any that meets these requirements. Semi-synthetic and synthetic lubricants behave much better in cold weather, ensuring rapid heating and maintaining their properties even at very low temperatures.

It is also important to purchase an original product without running into a fake, therefore you need to buy oil from trusted sellers who have the appropriate certificates confirming the quality of the products.

On the very first cars produced, the same oil was used for the transmission that was poured into the engine. This was also recommended by the manufacturer. Now there is no shortage of auto chemicals, so it is better to use specialized products for their intended purpose.

What can you put into the “nine” today?

With the development of the automotive market in Russia, the number of transmission oil manufacturers increases every year. What kind of oil can be poured into the “nine” box now? Experts recommend purchasing substances for the VAZ 2109 gearbox that correspond to API group GL-4. According to GOST, these can be TM-4 and TM 5-9P oils. Based on viscosity characteristics, it is better to focus on choosing products with the following SAE marking:

This is the kind of oil that experts recommend pouring into the “nine” gearbox. It is these fluids that are most suitable for gearboxes of VAZ 2109 and VAZ 2108 cars. They have a very long service life and ensure smooth operation of gearbox parts over several tens of thousands of kilometers.

Topping up oil

Regularly checking the fluid level in the VAZ-2109 box will allow you to maintain the device in good condition for many years.

Based on the marks on the dipstick, add oil if necessary. It is very important to maintain the transmission fluid level at the maximum level. A drop in volumes to a minimum leads to severe wear and tear on the car's gearbox, as a result of which it is at risk of repair or complete failure. Topping up is carried out using a dipstick and a funnel into the hole of the measuring device, where oil should be poured if the gearbox is serviced. In case the car does not have a dipstick, a syringe is used and liquid is added to the hole in the filler neck.

Topping up results in a product that is exclusively identical to what was used previously; mixing different compositions can have an extremely negative impact on the box.

What you need to change the oil

To replace it yourself, you will need at least the following:

  • jack, inspection hole or lift;
  • wheel bolt wrench;
  • open-end or socket wrench 17;
  • empty waste container;
  • a syringe or other device for pouring oil;

  • clean rags.

When preparing for a replacement, there are a few things to consider.

  1. It is necessary to take into account how much oil is in the VAZ 2109 gearbox. That is, the container for the old lubricant must be selected appropriately, so as not to subsequently collect spilled waste. If you are the only owner of the car, are replacing it for the first time and are sure that there have been no unqualified interventions before, then the maximum volume of oil in the box will not exceed 3.3 liters. Accordingly, a 4-5 liter canister is quite suitable for this purpose. If the box has a dipstick, you can first check the lubricant level. Often a plastic 5-liter bottle of technical liquids is used as a waste container.
  2. It is necessary to take care of safety. Changing the oil in a manual transmission requires a person to partially remain under the front wheel arch. Therefore, it is important to follow at least two basic rules: securely stop the car and install a safety stand in case the jack falls.
