Having first appeared in 1975, the VAZ “six” turned out to be a long-liver, and with figures close to record ones: it was produced until 2005, that is, 30 years, and during this time about 4 million copies rolled off the assembly line. It is safe to say that this model is one of the most popular models in the global automotive industry.
It is not surprising that today the VAZ-2106, along with all its modifications, is a frequently encountered car on the roads of post-Soviet countries. Relatively low cost, availability of spare parts and ease of operation, maintenance and repair are the main advantages of this model. Most car repair and maintenance operations can be done on your own, including changing the oil in the VAZ-2106 gearbox.
We will tell you about it today.
How often to change transmission oil
According to the manufacturer’s recommendations, the frequency of oil changes in a “six” manual transmission is every 75 thousand kilometers. Such an impressive interval is quite understandable - transmission oil does not work under such extreme conditions as engine oil, so this indicator can be considered optimal. However, when operating a car in difficult conditions, the frequency recommended by AvtoVAZ may not be enough - many Six car owners perform this operation after a mileage of 60 thousand km.
Checkpoint "Niva Chevrolet"
The domestic SUV is extremely passable and reliable, but requires careful maintenance. In particular, this applies to a manual transmission. It is allowed to use oil of group GL-4/GL-5 or GL-5. For normal operation of the unit, oils with the following viscosity are best suited: SAE 75W-90, 80W-85 and 80W-90. If you comply with all the above requirements, the box will work much quieter and longer.
Among motorists, a rating of proven transmission oils has long been formed. It is best to pay attention to them. If you are asking the question: “Which gear oil is best for the Chevrolet Niva?”, then you should definitely try Eneos 80W90 Gear GL5. This lubricant showed excellent performance at low temperatures, maintaining acceptable fluidity. True, it is sold only in 4-liter cans, which is not very convenient. Also, many motorists advise trying Castrol Syntrax Universal Plus. This is an expensive transmission that provides impeccable softness of gear shifting with a long replacement interval - 300 thousand kilometers.
Recommendations for choosing oil
Any oil with viscosity values 75W90, 75W85, 80W85, 80W90, 85W90 is suitable for filling into a mechanical five- or four-speed VAZ gearbox. Questions arise when it is necessary to solve the dilemma of which oil is better to fill in the VAZ-2106 gearbox: mineral water, semi-synthetic or synthetic.
An important and at the same time practically the only advantage of mineral water is its low cost, which is one and a half to two times lower than synthetics or semi-synthetics. This is due to the composition of such a lubricating fluid, which does not contain any additives. At the same time, the lubricating properties of mineral oil are quite decent, allowing you to operate a car without changing the oil for 60 - 75 thousand kilometers. A significant disadvantage of mineral water is a decrease in viscosity in severe frost, which makes it difficult to change gears on a cold engine.
The only drawback of semi-synthetic and synthetic gear oils is their high cost. But they have more than enough advantages: excellent manufacturability, the presence of wear-reducing additives for gearbox parts, and the possibility of trouble-free operation in a wide temperature range.

Among some car enthusiasts, there is an opinion that the use of synthetic oil in the VAZ-2106 gearbox contributes to squeezing out the oil seals, which leads to their leakage. In reality, such problems have nothing to do with the type of transmission fluid used; their cause lies in the wear of parts and components of the gearbox.
What and when to pour into the VAZ-2110 gearbox?
The box, which is used in the domestic “ten”, is quite durable and hardy. But this is only subject to proper operation and timely replacement of transmission oil. The most suitable for the VAZ-2110 gearbox can be considered a synthetic base. This is especially true for cars that are operated in extreme conditions. True, synthetics have one drawback, which is their high cost. But, given the replacement interval, you can spend money. As a last resort, it is permissible to use semi-synthetic oils. But you can’t mix synthetics and semi-synthetics. You shouldn't forget about this.
If we talk about which gear oil is best for the VAZ-2110, then the first thing you need to decide on is the viscosity. There are summer, winter and all-season transmission oils. The latter are the most popular due to their versatility. True, the price tag for such a lubricant is a little higher, but it’s worth it. The manufacturer recommends TM-14-2 oil, which is what needs to be poured into the box. There are better analogues, such as Lukoil-Super. True, the base here is mineral, so it is not suitable for gears, but it supports the operation of synchronizers perfectly. Valvoline SynPower is a Dutch synthetic oil. It is expensive, but the performance characteristics are at the highest level.
Tools and accessories
To change the oil in the “six” yourself, you will need the following tools and materials:
- wrench 17 (if the fasteners do not give in, an extension wrench may be required);
- a 12mm hex wrench, preferably also with a long tube, to increase the leverage of the applied force;
- waste container with a volume of 2 liters;
- a special syringe characterized by a curved end (a regular medical syringe is also suitable; instead of a needle, a hose about 25 centimeters long is attached to it);
- rags.
To change the oil, it is advisable to place the car in a pit or overpass; to top up the transmission fluid, this is not necessary.
What tool will you need?
Advice. It is best to change the oil in an inspection pit or on an overpass. It just won’t be pleasant when hot oil pours on you lying under the car!
Tools
To carry out the replacement procedure, you will need the following tools:
- an open-end or ring wrench for seventeen (if the part is stuck, you can use a head with a knob);
- twelve hexagon with a longer tube for increasing the action lever;
- two-liter container for waste water;
- a special syringe for filling lubricating water, the end of which has a curved tube, or an ordinary syringe with a hose about 20-25 cm long attached to it;
- unstained rag.
It is better to carry out the replacement in an inspection hole, overpass or lift - this way it is more convenient to drain the lubricant.
How to check the oil level in a box with topping up
It is recommended to check the transmission oil level in the VAZ-2106 gearbox on a cold car. If the procedure is carried out immediately after a trip, you must wait at least 10 minutes (depending on the time of year and ambient temperature) for the oil to drain from the gearbox parts into the crankcase.
The level is checked not using a dipstick, as on an engine - it is filled to the upper edge of the filler hole located on the side plane of the gearbox.
The algorithm for checking and topping up the oil level in the gearbox is extremely simple:
- unscrew the oil filler plug, clean it of dirt, use a metal brush if necessary, wipe it dry;
- checking the oil level - visual: if there is more than needed, it will flow out of the hole, if less, it needs to be added using a syringe;
- screw the oil filler plug into place;
- Wipe away transmission fluid leaks with a rag.
The best choice for domestic classics
Mechanical gearboxes, which are installed on domestic cars, have several irrefutable advantages. Firstly, this is an extremely reliable unit that does not require expensive maintenance. Even if there is a need for major repairs, it will be relatively inexpensive.
However, regular maintenance should not be neglected. It is advisable to purchase lubricant from trusted places and not skimp. The replacement interval is 3-4 years or 150 thousand kilometers, whichever comes first. This is not motor oil that needs to be changed every 8-10 thousand miles. An excellent choice would be Castrol or Motul. From budget and high-quality, I can recommend.
Complete oil change
Since checking the oil level is not required, it is advisable to change it when the car is warm. Sequencing:
- We install the car on a pit, overpass or blocks to gain access to the drain hole located on the bottom of the box housing.
- We place the prepared container under the drain hole.
- We unscrew the drain plug using a hex wrench, being extremely careful as the oil is hot.
- When the waste stops dripping, carefully clean the drain hole and seat from dirt, tighten the drain plug without being too enthusiastic (so as not to strip the thread).
- Using a socket or wrench 17, unscrew the filler plug located on the side wall of the box on the right along the direction of the car.
- Filling with fresh transmission oil is done using a special syringe with a curved end, although it is quite possible to use a regular large-volume syringe by attaching a rubber or plastic hose 15–25 cm long to its lower end using tape.
- Since the volume of a special syringe is 500 cm3, and it is also quite difficult to find a syringe of a larger volume in pharmacies, filling should be done several times, and quite slowly.
- When liquid begins to flow out of the filler hole through the top, this means that the required level has been reached.
- We tighten the plug, also without applying excessive force.
- We check for the presence or absence of leaks, first of all from the drain hole. If necessary, tighten the plug.
After completing the procedure, we check the used oil for the presence of metal shavings, crumbs and microparticles. If any, this indicates the need for transmission repair. We visually inspect the housing for cracks and leaks; if they are present, it is necessary to eliminate the detected defects.
If the waste is black in color, indicating that it is heavily contaminated, it is advisable to flush the gearbox housing before changing the oil in a manual transmission in a VAZ model 2106. For this procedure, you will need to mix 0.7 liters of transmission fluid and 0.3 liters of diesel fuel (you can use a ready-made flushing mixture sold in auto chemical departments). We pour the resulting liquid into the box, jack up one of the drive wheels, start the engine, and let the engine run in one of the forward gears for several minutes. Drain the flushing fluid and fill in new one.
Regularly checking the oil level and quality will help determine whether it needs to be replaced ahead of schedule. If the transmission fluid becomes very dark, an unscheduled replacement should be carried out, which will help extend the life of the manual transmission.
How much oil is in the manual transmission of a VAZ 2106
First generation 2106, 1976-2006
The new sixth model sedan went into production in 1975, when it replaced the VAZ-2103. Compared to its predecessor, the car stood out with updated bumpers, modified front fascia and new rear lights. The interior has been slightly transformed due to a different finish on the door cards, as well as an alarm button. One of the basic versions 2106 (21063) had a 63-horsepower 1.3-liter unit under the hood, as well as a 78-horsepower 1.6 engine, based on the 1.5 engine from the VAZ-2013. In 1987, sales of the “six” with a 5-speed manual transmission began, and in the early 90s the car received improved design outside and inside. By the end of the 90s, it became possible to install electric windows. One of the most expensive versions, called VAZ-21065, was distinguished by different seat upholstery, the presence of a contactless ignition system, a heated rear window and a five-speed manual transmission. The latest batches of the “six” were offered with an 80-horsepower 1.6-liter injection engine.

Replacement frequency, what oil to fill
According to the manufacturer's regulations, service changes of engine oil on the VAZ 2106 are carried out after 8,000-10,000 kilometers or at intervals of 1 year. But some car owners consider this interval to be a little too high, recommending that it be shortened taking into account operating conditions.
It is recommended to use semi-synthetic with a viscosity of 10W-40 as a lubricant. The following motor oils are most popular among model owners:
- Lada Professional 10W-40
- Lukoil Genesis Advanced 10W-40
- Shell Helix HX7 10W-40
- Total Quartz 7000 10W-40
When using this car in winter, you should select oil taking into account the climate zone, as well as the recommendations of AvtoVAZ. Viscosity 5W-40 will allow you to operate the car down to -30°C, and 0W-40 up to -35°C.
