Why change transmission fluid?
Like any other lubricant, the composition for manual and automatic transmissions performs a number of important functions:
- Extends the service life of the unit. During friction of parts, wear will be inevitable, but oil improves the sliding of gears and increases the service life of all components.
- Cleansing. When the gearbox operates, metal shavings are generated, which in large quantities can pose a danger to the gearbox. One of the functions of the oil is to carry these chips to a collection area where the magnet is usually installed.
- Structural protection. The metal is susceptible to corrosion. To prevent oxidative reactions, the oil creates a film on the surfaces of parts.
- Reducing noise and vibration from gearbox operation, heat removal, reducing shock loads during switching.
Thus, transmission oil is an essential component, without which the operation of the gearbox will be impossible.
Another question is whether replacement is necessary, because many automakers claim that the transmission fluid resource is enough for the entire life of the car. Let's figure this out. It’s worth starting with the fact that the maximum shelf life of liquid in packaging is 5 years. Now imagine that the oil is actively used in the gearbox and gradually becomes contaminated with shavings and other small particles. Naturally, talking about unlimited service life is very stupid, especially if you actively drive your car.
Why do manufacturers then make such statements? It’s all very simple. It's about marketing. If the driver changes the transmission fluid on his own, the gearbox will not break down and the automaker will be left without additional income. The sale of spare parts for a car is a significant share of profit, so it is beneficial for companies that the car owner contacts branded technical centers for repairs and maintenance as often as possible.
If you want to save on auto mechanic services, it is better to fill the Renault Logan gearbox with oil as soon as the old one begins to lose its performance characteristics.
Gearbox unit (recommendations for maintenance and oil change)
The following two tabs change content below.
- About the expert:
Renault car expert
I own a Renault Megane 2, before that there were Citroens and Peugeots. I work in the service area of a dealership, so I know the car inside and out. You can always contact me for advice.
The gearbox unit is serviceable. But the oil that is filled from the factory is designed for the entire period of operation. And the manufacturer does not specifically indicate when to change the oil in the Renault Logan gearbox!
The point is that the fluid needs to be added, but not changed. This is what the Renault regulations look like. Let's consider the question of when replacement is made in reality:
- At 12-13 thousand mileage, the gearbox oil will be transparent;
- After 80-90 thousand it will be black.
Based on these two statements, you can decide whether it’s better to change or wait.
According to the owners' experience
In reality, Renault Logan owners act differently:
- When the clutch basket was replaced, the oil was drained from the box. There was a good argument to replace the fluid completely, at the same time replacing the clutch cable, this is a disease.
- The first replacement was made after 190 thousand kilometers;
- When buying a car, the owner decided that the service interval would be 60 thousand km.
190 and 60 – these numbers differ by an order of magnitude. And both are puzzling. Regarding the first point, we note that the owner prepared for the replacement in advance: the box was warmed up, the plug was purchased immediately. We advise you to do the same.
The process of adding and changing oil
First of all, we recommend buying a “plug with washer” kit (7703 075 180 VAZ, 7703075180 Renault). The plug closes the drain hole (see figure). The required volume for changing is 3.1 liters of oil.
A new plug is screwed in here
To wash off all deposits, replacement is carried out on a heated box. And it is better to replace it in the warm season.

Deciding on frequency
As mentioned earlier, the manufacturer does not make any recommendations regarding changing transmission oil and does not even recommend this operation. Auto mechanics are of the opinion that Renault Logan manual transmission oil should be changed every 100-120 thousand kilometers. These are arbitrary numbers, since the fluid may become unusable even earlier if the gearbox was operated under extreme conditions.
An automatic transmission is much more complex in its design. Oil changes in Renault Logan automatic transmissions occur more often (approximately every 50-60 thousand kilometers). It is not recommended to exceed the presented values. Neglecting to replace transmission fluid will result in accelerated wear of parts and the need to replace them. In the most critical situations, the box can completely jam. In this case, you cannot drive a car, so you will have to call a tow truck and go to the nearest service station.
The choice of the plant or the choice of the people!?
The manufacturer recommends branded transmission oil for replacement in a manual transmission (MTF marking): ELF Tranself NFJ 75W80
(semi-synthetic),
75 W90
(synthetic), (the price for 1 liter today is within 600 rubles).
.
The automatic transmission, according to the “manual” from the factory, should be filled with ELF Renaultmatic D3 Syn, which will be enough for a complete replacement of about 4 liters
.
Experienced “Loganovods”, through personal trial and error in changing transmission oil, identify leaders whose quality and technical properties are in no way inferior to those recommended from the Renault plant.
Despite all of the above, fans of Renault Logan cars note that it is an obvious outsider and do not recommend replacing it with SHELL Getriebeoil EP 75w90 GL4
. Judging by the dissatisfied statements, the manual transmission in tandem with gear oil from this manufacturer begins to behave like a worried stallion. In almost all cases, there is a hum, crunching and noise from the gearbox.
Signs of wear
It is necessary to rely only partially on mileage values, since fluid wear depends on individual driving habits and the condition of the transmission. We recommend studying the main symptoms that will tell you when to fill in new gear oil:
- the appearance of loud extraneous noise, especially when operating in neutral gear;
- Difficulty in shifting gears;
- “sluggish” operation of the switching mechanisms, which is especially noticeable in automatic transmissions;
- the appearance of vibrations or beating in the shift handle;
- the appearance of a burning smell.
All this may indicate a breakdown of any part of the assembly. However, first of all, start by changing the oil, and only then carry out detailed diagnostics.
Topping up for “mechanics”
It should be borne in mind that for “mechanics” it is generally not expected to completely change the oil or top up.
According to the official requirements of the manufacturer, it is poured into the manual transmission for the entire life of the vehicle. However, since none of the foreign automakers for some reason expects that the car will drive for more than 5, and even more so 10 years before overhaul, it is best to add a little of this consumable to the manual transmission. This will not only increase the service life, but will solve some of the problems with gear shifting difficulties. In order to determine how much lubricant is required for Sandero, it is worth checking its quantity inside the gearbox. Before starting work, this can only be done approximately by sticking your finger into the Sandero manual transmission.
Changing the lubricant for a Renault Sandero manual transmission in this case does not involve performing serious work. All you need to do is:
- Prepare the required volume (up to 3 liters);
- Open the drain hole;
- Using a plastic syringe or a transparent hose, pour in the required amount of consumables (you can see the process in more detail using a special video).
It is recommended not to perform the topping process too quickly. After all, the only way to determine what is enough is the oil pouring out of the manual transmission.
Types of oils
All products are divided into several groups (depending on the base used). There are mineral and synthetic transmission fluids. The former are most often used on older cars, where the gearbox has a lot of wear. Mineral compositions are the cheapest, have a relatively short service life, and to increase their anti-corrosion and leaching properties, all kinds of additives are added to them.
The gearboxes of modern cars are filled with synthetic (less often semi-synthetic) oil. It has the best performance qualities: long service life, preservation of viscosity indicators over a wide temperature range and effective protection against corrosion.
Additionally, we recommend paying attention to the markings according to the SAE standard. It shows in what temperature range the oil retains its viscosity characteristics. Typically, cars are filled with all-season models, which are designated as two numbers separated by the letter W, for example, 75W80. Using these numbers, based on special tables, you can determine the maximum and minimum operating temperature of the composition. If you are looking for analogues, then check that the SAE marking is similar to the original.
Oil change instructions
1. Place the machine on a level surface.
2.Unscrew the engine and transmission crankcase protection. In some variations, the protection has a technological hole for unscrewing the drain plug.
3. Clean the gearbox housing from dirt and dust in the drain area and near the filler hole. If drained oil is to be reused, the area near the drain plug must be clean.
4.Unscrew the drain plug using a 8-square. After loosening it with a wrench/ratchet, we recommend turning the plug out manually to quickly remove it from the stream of draining waste. An increase in backlash indicates the end of the thread.
If the color of the drained oil is cloudy, with an emulsion, then there are water impurities in the oil.
5.Use pliers to unscrew the filler plug, which is located at the end of the right side of the box. It is not necessary to change the gasket on this plug.
6.Tighten the drain plug. It is advisable to replace the sealing gasket.
7. To fill in new oil, use a homemade funnel with a piece of hose or a special syringe for filling technical fluids. First pass the hose through the top of the engine compartment, and then direct it from below into the filler hole.
Pour oil into the box until it flows out of the filler hole. The same method is used for in-line level checking. As soon as the oil has stopped flowing out of the filler hole (which is why the car is placed on a flat surface), tighten the plug by hand, wipe off any oily traces and install the engine protection.

What oil to use
Let's move on to specifics and find out what kind of oil to pour into the Renault Logan box. Let us remind you that cars are produced with two gearboxes: automatic and manual. For manual transmissions, the automaker recommends a product called Elf Tranself NFJ 75w-80. This is a high-quality product, so it is recommended to fill only the original. You will need about 3.5 liters, but it is best to buy 4 liters with a reserve. If you choose analogues, make sure that the composition meets the API GL-4 quality class and has a similar SAE marking.
For the automatic transmission, ELF RENAULTMATIC D3 is used (catalog number 194754). The oil volume in the Renault Logan gearbox is up to 3 liters. The cost of this product varies depending on the region, but on average it is 500 rubles. As an analogue, you can look for Castrol Syntrans Transaxle 75W-90 or MOTUL Gear 300 75W-90, but drivers recommend using only branded products recommended by Renault itself.
Please note that using a composition with characteristics that differ from those required will lead to disruption of the gearbox. For example, too high a viscosity will make gears difficult to function. As a result of this, the box will operate under increased loads. Once you have decided how much oil needs to be poured into the Renault Logan gearbox and have bought everything you need, you can start replacing it.
Be careful, because there are a huge number of fake branded formulations sold on the market. They do not have the characteristics of the original, but they can cost the same. Here it is important to pay attention to the packaging, its shape, color, quality of label printing and the presence of any defects.
When is it necessary to change the gearbox oil?
Oil drained from the gearbox at 60 thousand km. It was already very dirty, so the checkpoint was working with problems
However, despite the fact that the manufacturer (by the way) did not set a time limit for changing transmission oil and fluids, explaining that this is not required for the correct and smooth operation of the gearbox, experienced craftsmen and mechanics of Renault car service centers, It is recommended to replace every 60,000-100,000 kilometers (depending on conditions and operating time).
And on the other hand, no one is immune from the fact that before this cherished mileage occurs, it will not be necessary, and then changing the oil in the gearbox becomes a desirable procedure. To avoid premature failure, watch out!
Preparatory activities
Regardless of your transmission type, you will definitely need to prepare a minimum set of tools. It includes:
- set of socket wrenches;
- special four-sided key 8 by 8 millimeters;
- pliers;
- metal brush;
- a funnel made from a regular plastic bottle and a hose with a cross-section for the filler hole;
- containers for used oil (volume is selected depending on the gearbox);
- flashlight or other lighting.
The drain hole is located in the bottom area, so it is most convenient to carry out work in a pit or using a lift. The most extreme option is to raise the front part with a jack, but in this case there will not be enough free space. Be sure to wear protective clothing, since transmission oil can be difficult to wash off.
Auto mechanics also recommend carrying out work on a warm engine. The temperature in the box should be 55-60 degrees. This will ensure better fluidity of the composition, but in this case, use mittens. The plug and the oil itself will be quite hot.
Solving the issue with the "automatic machine"
When using a Renault Sandero with an automatic transmission, it is assumed that topping up is carried out at least once a year, and replacement – once every 5 years. Moreover, regardless of whether the owner travels often or not. After 10–15 months, aging oil loses its properties and is less suitable for use.
To top up, you need to have a filter and a transmission pan gasket, as well as perform the following work steps:
- Drive into the pit, placing the Sandero automatic transmission lever in the “parking lock” (“P”);
- Start the Sandero engine and warm it up until the unit heats up to 60 degrees;
- Unscrew the outer nut without turning off the engine;
- See how much consumable has spilled out - if it is more than 100 ml, it means that its level in the gearbox is normal and topping up is not required. If little liquid comes out, continue working;
- The engine is turned off to allow the device to cool to fifty degrees;
- The filler nut is unscrewed;
- Add up to 300 ml of oil.
Now you should check again how much fluid is poured out of the Sandero automatic transmission when it is reheated to 60 degrees. The steps are repeated until more than 100 ml of consumable is poured out.
Replacing transmission fluid in a Logan manual transmission
Most Logan cars have a manual transmission, so let's look at the process for that:
- To make work easier, remove the engine protection. It is secured with several bolts.
- Locate the drain hole. It is located on the side of the engine oil drain hole. Place an empty container. Using an 8x8 wrench, unscrew the cap.
- Once all the oil has been drained, use pliers to unscrew the filler plug. It is located a little closer to the front bumper relative to the previous hole. Positioned horizontally.
- Tighten the drain hole, it is advisable to replace the gasket.
- Pass a hose through the engine compartment and insert its end into the oil fill hole.
- Start pouring the new mixture into the funnel. Fill until liquid begins to flow out of the drain hole in a thin stream. Please note that the machine must be on a completely level surface.
- As soon as the thin stream stops running, screw the lids on.
This completes the process. Checking the oil level in the Renault Logan gearbox is carried out exactly at the filler hole. It is also often called control.
Types of checkpoints
Namely: manual - which most cars on the market are equipped with, and automatic - not very popular in our country and presented exclusively in top-spec models.
Manual transmission
The manual transmission is presented by the manufacturer in two versions jH1 (1.4) and jH3 (1.6) - which differ from each other only in the size of the clutch housing.
JH3 gearbox on a Renault Logan car with an engine capacity of 1.6 liters
JH1 gearbox on a Renault Logan car with an engine capacity of 1.4 liters
Accordingly, the same oil is used for two different types of manual transmissions. About,
Automatic transmission
Unlike a five-speed manual transmission, an automatic transmission has only 4 gears and instead of oil, a special hydraulic fluid is poured into the “box”, the resource of which, as a rule, is enough for the entire period of use of the car. .
Replacing transmission fluid in a Logan automatic transmission
There are no fundamental differences in changing the oil for automatic transmissions in Renault Logan cars. It is necessary similarly:
- Remove the protective panel under the bottom, unscrew the drain plug and drain the used transmission fluid.
- Approximately 1.8-2 liters will drain. Then the level flask located nearby is unscrewed.
- Wait until more liquid flows out of it, and then unscrew this part with a 8-mm hexagon. By completely removing the plastic flask, you can drain the remaining oil. A total of about 3.5 liters should come out.
- Replace the level flask and plug. Don't over-tighten them.
- In the engine compartment, find the filler hole, next to the air duct, which will have to be removed. Add the required amount of new transmission oil.
- Start the car and warm it up to 90 degrees. Click all gears (D, N, R, P). At the end, set the position P - “parking”.
- With the car running, unscrew the drain hole. 100-300 milliliters of liquid should flow out of it. As soon as it starts to drip slowly from the hole, screw the cap back into place.
- Next, you need to add oil to the Renault Logan box (approximately half of the drained volume of liquid). If 0.5 liters leak out, then add 0.25 liters.
- Tighten the filler plug and put all components in place (air duct, crankcase protection).
Thus, changing the Renault Logan automatic transmission oil is a little more complicated, since the work has to be done in several stages. It is very important to warm up the engine. Without special stands, mechanics advise warming up the engine to 90 degrees and starting replacing it in a couple of minutes. The whole process will take you about 1 hour. Finally, be sure to take it for a test drive. Make sure that the problems with the gearbox have disappeared, and the unit has become quieter and gear shifts have become softer.
This is a partial replacement procedure. It will be impossible to completely change all the oil yourself in a garage, but in this way you change 3-4 out of 6 liters, so the unit will work with high-quality lubrication.
A lack of transmission fluid in an automatic transmission is dangerous because the pump will begin to swallow air. Such a mixture has different characteristics from oil, and therefore is not able to ensure normal operation of the gearbox. The result is regular overheating and wear of the assembly parts. Considering the high cost of automation on Logan, it is in the driver’s interests to achieve the longest possible service life.
It is important to know!
Changing the oil in the gearbox, regardless of its type, is a very important and responsible procedure. The quality and condition of the oil plays a primary role in the longevity of your gearbox. After all, just imagine how many different parts are there: gears, bearings, shafts.
All parts move at unimaginable speeds, and in order to protect them from the heat generated by friction, as well as the influence of external factors affecting the gearbox, it is important to know which gear oil will be useful. Just like the motor one, it has three types of base: mineral, semi-synthetic and synthetic.
Types of gear oil
- Mineral
oil is the cheapest and most accessible oil on the market. This type of oil is added to mixtures with various additives (which contain sulfur), since in itself it is quite unstable. - Semi-synthetics
are somewhere in the middle of the price and technological category of the category between “mineral” and “synthetic”. Due to the fact that semi-synthetic oil has the thickest viscosity, it is ideal for use on cars with high mileage. - Synthetic
is a very fluid type of oil. Since its properties do not depend on external conditions (negative ambient temperature), this type of fluid does not thicken in the cold, thereby allowing all parts in the gearbox to work easier without losing performance.
Be careful!
Do not fill or mix different types of gear oil.
Since different manufacturing plants use different technologies when producing oils, the product itself is varied and has different characteristics and properties. Therefore, if you want your gearbox to serve you for a long time, it is better not to experiment!
Hi all! The topic of today's article is Renault Logan gearbox oil. As you may have guessed from the title, the article will contain video instructions for changing the oil, recommendations for choosing oil and filling volumes.
The manufacturer believes that the oil will retain its properties throughout the entire life of the vehicle.
But we live in Russia, where there are no roads, a lot of dust and dirt and a temperature difference of 80 degrees, and all these conditions negatively affect the health of cars. Accordingly, when the grenade boots break and the oil seals wear out, dirt, dust and water inevitably get into the gearbox! Naturally, in Russian realities it is better to change the oil in the box, and the owners have experimentally established that this should be done after 60-100 thousand km. mileage or when repairing the box and related elements.
What kind of oil is poured into the Renault Logan box at the factory?
ELF Tranself NFJ 75W80 in the box of Logan 1.4 and 1.6 is 3 liters and it looks like this:
What kind of oil is allowed to be poured into a Logan box when operating in the Russian Federation?
Friends, let's agree that the recommendation of ELF Renault oil is nothing more than a marketing ploy... Oil viscosity is indicated according to SAE, and there is nothing wrong if you fill in high-quality GL4 synthetic oil with a viscosity of 75w-80 from any other manufacturer. The main thing is that the oil is of high quality.
Regarding the problem of choosing between mineral, semi-synthetic and synthetic, you should definitely choose synthetic oil, since it is more stable over the entire temperature range and has a longer service life. Although the author of this article has seen a Logan with a mileage of 280,000 km from a taxi, the owner of which poured Lukoil mineral water into the box, the author does not recommend doing this.

How to change the oil in a Renault Logan manual transmission with a 1.6 engine
There is no point in writing separate instructions for changing the oil in the box of a Logan with a 1.6 engine, since the boxes differ structurally only in the size of the clutch housing, while the boxes themselves are the same and the filling volume of oil and its type are also the same. Therefore, you can do everything according to the instructions given above.
That's all for me today. Good luck to you, good luck on the roads and good health.

A car, as everyone knows, consumes not only gasoline, but also contains additional filling fluids. But often car owners go to a service center because they don’t know how and how much to fill antifreeze, hydraulics, motor oil into the engine, etc. And that’s why go to a service center and pay your own money when you can do it all yourself . If you are the owner of Renault Logan, then you are very lucky that you have come to this page, because we will talk about this particular car.
Other reasons for topping up
You can determine the need for topping up before the expected date by regularly monitoring the presence of leaks on the Renault Sandero manual transmission. In this case, you can also detect the malfunction that causes the leak. Often the problem is with the left drive. You can also understand the need for topping up by the increased noise of the gearbox during a trip - first it manifests itself in the top gears, and then in all gears. Having noticed a leak in time, you can fix it and do without constant additions.
Replacement process
The process of changing the oil in a manual transmission in a Renault Sandero Stepway is not very difficult, provided that there are no additional problems. And here it is worth considering one important point: if there are lubricant leaks, the origin of which is unknown, a knock is heard in the box, and after maintenance there are problems with gear shifting, you need to contact a specialist. It is not recommended to carry out repairs yourself if you do not have the necessary skills.
First, it is recommended to check the condition of the lubricant in the gearbox. It is necessary to clarify whether new gear oil is required for the Renault Sandero Stepway. The liquid should be level with the lower edge of the filler hole (closed with a plastic screw plug). Be sure to check the condition of the liquid: whether it has stratified (there are denser, viscous fractions in the lower part of the box), how clogged it is, etc.
It is worth mentioning the tools for changing the oil in a manual transmission in Renault Sandero Stepway. And the list here is very small. You need an 8-square wrench to open the drain hole, a screwdriver to remove the crankcase protection, a 4-5 liter container to remove used oil, and a canister of new lubricant (3-3.5 liters is enough). Additionally, if the gearbox is heavily soiled, transmission cleaning fluid will be useful. Cleaning can be carried out either with regular oil (buy 2-3 liters more than required for replacement) or with special compounds.
Regarding safety precautions, everything is simple and clear:
- The machine must be secured on a level surface. Stoppers are installed under the wheels, the car itself is put into speed and the handbrake is put on. It must be fixed carefully to avoid injuries and other troubles.
- Before work, it is recommended to warm the oil to a warm state to reduce viscosity (especially important in the cold season). But you should not work with a hot manual transmission, to avoid burns due to hot lubricant getting on the skin or accidentally touching the gearbox housing.
- It must be remembered that the oil should not enter the body.
And the process of preparing for draining the liquid is as follows:
- The machine is installed on an overpass or above an inspection hole. It must be fixed according to the principle described above (in the safety regulations).
- Using a screwdriver, remove the screws holding the crankcase guard in place. Then it is removed to the side until the replacement process is completed.
- Place a pre-prepared container under the drain hole.
- Wipe off dust and dirt from the gearbox (in particular, from the filler and drain plugs). During the process, you need to make sure that there are no leaks or damage to the manual transmission.
