Transmissions of one of the most popular French-made foreign cars must function in the process of constant lubrication of internal areas and parts. Lack of lubrication in the Renault Logan gearbox can lead to incorrect operation of the unit. It is very important to understand what specific fluid needs to be poured into the unit and follow the manual for changing the oil in a Renault Logan gearbox on your own.
To change the oil in the Renault Logan gearbox, you can use analogues of the original lubricant.

Which oil to choose for Renault Logan
Changing the oil in Renault Logan is not difficult, but before performing this action, you need to choose the right replacement fluid.
However, one cannot help but note the fact that many experienced motorists, from their own experience, have identified other leaders among transmission oils. In terms of quality and technical characteristics, they are in no way inferior to the fluids recommended by the Renault factory.
In particular, according to reviews from a large number of car enthusiasts, Casrtol Syntrans Transaxle 75W-90 is the best analogue of its kind. With its presence, gear shifting is much smoother, and when you engage reverse gear, the characteristic crunch disappears.
To change the oil in gearbox, you can also use MOTUL GEAR 300 75 W-90 , which, like the previous option, promotes smooth gear shifting and the absence of any extraneous noise.
Among the lubricating fluids that ended up in last place, Renault Logan owners singled out SHELL Getriebeoil EP 75w90 GL4, which, judging by the dissatisfied comments of users of various forums, when paired with gear oil from the automaker, begins to behave very ambiguously. In most cases, you can observe a hum, crunching and noise in the gearbox.
It is likely that there are some other good alternatives to oil in Renault Logan, but you can only check this by trial and error, pouring more and more new compounds into the gearbox of your car.
When an oil change is needed, manufacturers' recommendations
There is an opinion among car owners that only the oil in the Renault Logan engine should be changed on a regular basis, since the lubricant in the gearbox does not need a service replacement and is designed for the entire service life of the gearbox. However, in certain situations (for example, when transmission components are being repaired), it is better to change the oil.
The most common reason for such actions is a violation of the seal seal, which causes the fluid level in the transmission box to decrease. In this case, the oil is changed together with the oil seal, since it is too difficult to select a lubricant identical to the factory version. In addition, there is always the possibility of incompatibility between the original oil and the one you plan to add to the gearbox.
Poor gear shifting, accompanied by grinding noise, can also be a reason to replace the transmission fluid. In such situations, the car reacts a little late to the driver's commands.
Despite the fact that the manufacturer has not set any deadlines for changing the transmission oil of Renault Logan cars , experienced service center specialists involved in the repair and maintenance of Renault models advise replacing the lubricant in the gearbox every 60,000-100,000 kilometers (the difference depends on the conditions and time of operation of the vehicle).
How to determine the amount of oil in a box
Often, instead of completely replacing the gearbox lubricant in Renault Logan, you are only required to add lubricant , for which you need to know how much oil is still in the box.
In the case of a manual transmission, this can be determined using the inspection hole located on it. It is located in the front part of the gearbox housing and is closed with a plastic plug.
The check should be carried out on a horizontally positioned vehicle, every time it undergoes a technical inspection, as well as in cases where there is even the slightest suspicion of an oil leak.
To carry out diagnostics, simply unscrew the plug, after wiping it with a clean rag, and look at the oil level, which
should be at the very edge of the inspection hole. The easiest way is to place your finger in the hole.
You can add oil using a syringe or hoses with a funnel.
How to perform the replacement, list of actions and necessary tools
Having figured out which oil is best to fill in an automatic or manual transmission of Renault Logan, you can buy the chosen option and safely move on to the replacement stage.
Which oil to choose
From production, the gearbox is filled with fluid, which is subsequently recommended for future use. For example, if there is a need to add oil to the unit. In Renault Logan mechanics with a 16-valve engine, under maintenance conditions, the manufacturer recommends pouring Elf Tranself NFJ 75w-80 oil. This mechanical transmission lubricant has the following characteristics:
- high fluidity at low air temperatures, which can guarantee easy gear shifting in winter;
- stable viscosity characteristics that exclude the possibility of noise when changing gearshift lever modes;
- The product uses a technique that eliminates accidental stopping of gears;
- the fluid manufacturer guarantees customers that the oil provides good protection of the mechanical element of the unit from rapid wear;
- good thermal resistance to temperature changes;
- the presence of a complex of additives in the oil, which makes it possible to guarantee extreme pressure protection of the teeth of metal gears when operating the unit under heavy loads;
- resistance of the lubricant to corrosion;
- protection of the internal components of the gearbox from rust.
In automatic transmissions, the vehicle manufacturer recommends using Elf Renaultmatic D3 SYN gear oil.
The owners of Logans have in fact developed a number of effective analogues that make it possible to guarantee reliable operation of the gearbox:
- Castrol Syntrans Transaxle 75W-90. The artificial liquid substance is one of the elite analogues. As a result of the oil filling, the gear lever will function easier and softer. If a cracking noise occurs during preparation for reverse gear operation, then the use of this oil will make it possible to rid the car of this trouble.
- MOTUL Gear 300 75W-90. No less a good analogue to standard oil. This lubricant eliminates extraneous noise from the gearbox.
Fluid replacement timing
First of all, we will discuss how it is usually necessary to replace the fluid in Logan transmissions. In the official document, the manufacturer does not indicate the period for changing the lubricant in cars manufactured in 2006, 2014 and other years of production. Engine oil is poured into the transmission for the entire period of use of the vehicle. However, under harsh conditions and constant use of the car on rough roads typical for our area, experts advise replacing the fluid in the Renault Logan after 60 - 100 thousand kilometers.
When else should you change the oil:
- if the lubricant has lost its properties and is unable to properly lubricate the components;
- when pulsations occur during transmission operation;
- when resonance occurs on the gear shift lever;
- if there is an unpleasant burning smell coming from the gearbox.
Changing the oil in a Renault Logan automatic transmission
The automatic transmission also has a special filler hole through which the fluid is replaced. Transmission oil for a Logan with an automatic transmission is required the same as for a car with a manual transmission, but its volume must be 3.5 liters.
Before starting the procedure, you need to warm up the engine and place the car over the pit or lift it on a lift. To control the oil change procedure in a Renault Logan 1.4 automatic transmission, you can connect a diagnostic device and establish contact with the control unit.
The inspection hole must be opened after the oil temperature reaches sixty degrees. If you don’t know which oil is suitable for a Renault Logan 1.6 box, then you can rest assured and use the same one as for a 1.4 engine: they have the same gearboxes. The oil will drain slowly, so you can place a previously prepared container under the car and take a break. After the container is filled, the control drain plug is put in place. How long does it take to change the oil in a Logan automatic transmission?
Criterias of choice
When choosing transmission fluid, pay attention to the specification and viscosity. The API classification is a generally accepted classification that, through testing, determines the effectiveness of extreme pressure and anti-corrosion additives. Elf Tranself NFJ 75W-80 corresponds to the GL-4+ class, which is recommended for use in synchronized manual transmissions of passenger cars. However, it is permissible to use GL-4 and the highest class - GL-5, which is designed for loaded hypoid gears.
The SAE marking shows low-temperature (number with index W) and high-temperature characteristics. 75W formulations are recommended for regions where the temperature does not drop below -40°C. If the car is operated at temperatures not lower than -26°C, oils with an index of 80W are poured into the manual transmission. As for high-temperature characteristics, in regions with a temperate climate, a viscosity grade of 85-90 can be used.
For Renault Logan, Sandero, Logan 2, Sandero 2, Lada Largus, you can safely use oils with SAE indexes: 75W-80, 75W-90, 75W-85 and an API specification of at least GL-4.
We are looking for a dipstick!
To carry out such a basic procedure as checking the oil level in the gearbox on a Renault Logan, you need to place the car on a flat horizontal surface and, if possible, equipped with a pit for technical inspection. It is best to get to the inspection hole from below the car, after first removing the engine crankcase protection.
If this is not possible, then when checking through the engine compartment, you can make sure that the control dipstick for checking the oil level in the Renault Logan gearbox is missing.
Oil inspection plug
Thus, the check is carried out through the control hole, which is located in the front part of the gearbox housing on the right side, and has the form of a bolt (plug) made of white plastic with wide petals (for the greatest comfort when checking, you may need to temporarily remove the wiring harness , from the oxygen concentration sensor block (lambda probe).
We unscrewed the plug, next to the photo you can see the gearbox cable
After you have discovered the plug, it and the part of the crankcase around it must be cleaned of dirt with a rag to prevent dirt from getting into the gearbox along with the oil. Next, you should unscrew the plug in the control hole clockwise, and if during this procedure the oil does not begin to ooze, its level must be checked with your finger. In ideal condition it should be at the level of the lower edge of the control hole.
If during inspection it was determined that the transmission fluid in the gearbox is less than normal, then it must be topped up using a special syringe or funnel. You need to know the oil volumes in the gearbox, they are here!
Note!
All work on checking the oil level in the gearbox should only be carried out with a “cooled” gearbox. Because such a check becomes most relevant and complete when all the transmission fluid has drained from all working units.
When to change gearbox oil?
How to determine the amount of oil and what volume should be in the box
If there is a need to change the oil in the Renault Logan gearbox or increase the required amount of fluid, the car owner should know how much oil is contained in the box. The oil volume in the manual transmission reaches approximately 3.5 liters. The amount of fluid in automatic transmissions is about four liters.
In order to find out the engine fluid level, you should perform the following steps:
- Warm up the car and place it on a smooth horizontal plane.
- If the car does not have a dipstick for checking the oil level, then control is performed using a special hole, which is located in the front part of the gearbox housing. There is a plastic cap in the hole; it must be wiped with a cloth and unscrewed.
- Then look into the hole. If you cannot determine the liquid level, you need to measure it by touch by dipping your finger into the hole. The oil volume is located in the area of the lower edge.
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.

Possible malfunctions after replacement
If the oil change is carried out correctly, the gearbox will last for the entire life of the vehicle. But some car enthusiasts do not clean the filler hole well from dust and soil, as a result of which the new oil becomes contaminated and loses its quality. This immediately affects the operation of the gearbox.
The bearings wear out quickly, a hum appears when the unit is operating, and extraneous sounds appear when changing gears. Spontaneous gear disengagement is possible while the vehicle is moving. If you do not take immediate action and fill in new lubricant, the gearbox will fail and you will have to take the car to a service center for major repairs.

Recommendations
When changing the gearbox oil, you may notice fine metal dust on the plug. Typically, a small amount of such dust indicates natural wear and tear of parts and is normal. However, the presence of metal shavings already indicates severe wear or damage to the gears and gearbox parts. In this case, the unit requires in-depth diagnostics and repair.
In the event that the owner is not sure of the quality and suitability of the poured oil, it is necessary to pay attention to the characteristic signs. Driving with unsuitable or low-quality (including counterfeit) transmission oil leads to bearing wear, gears are difficult to engage, gearbox noise appears, a crunching sound may occur when shifting, etc.
In such a situation, you urgently need to drain the gearbox oil, then fill it with high-quality fluid that fully complies with all the requirements and tolerances of the car manufacturer. For Renault Logan, it is better to use original oil in the box. Ignoring this requirement may lead to complete failure of the gearbox.
DIY oil change
You can replace the lubricant in Renault or Dacia Logan at a service station or yourself. Let's look at how to change the product yourself.
Tools and materials
To change the lubricant, prepare:
- an old bucket or basin, this container will be used to collect waste liquid;
- new oil;
- wrenches 8 and 10;
- transparent hose with watering can.
Stages of work
The procedure for draining and filling grease is as follows:
- The car warms up and is driven into a garage with a pit.
- You need to crawl under the bottom of the car and unscrew the bolts that secure the engine protection. This will make changing the oil easier.
- It is necessary to find the drain plug and place a container under it to collect the waste.
- Then you should unscrew the bolt and wait until all the oil comes out of the gearbox. Then assess the condition of the drain plug and its seal, which must be replaced as it wears out quickly.
- You need to find a hole to control the level. Then insert one end of the prepared hose into it, and connect the watering can to the other. You can begin the liquid filling procedure. This is done until the oil begins to come out of the inspection hole. The amount of lubricant to be filled depends on the type of transmission.
- Use a rag to remove any remaining substance from the gearbox housing. Screw on the filler cap.
- It is necessary to reinstall the power unit protection and clean the transmission breather.
Replacing ATF in automatic transmission
You should also prepare for work on replacing the working fluid in an automatic Logan box. If you need to partially change the fluid, you should purchase 4 liter canisters of Elf Renaultmatic D3 Syn. To completely renew the lubricant, you will need to change the ATF in the automatic gear shift unit at least 2 times. After the first shift, drive 200–300 kilometers, then drain this fluid and replace it again.
All available means are the same as when changing manual transmission lubricant, only the socket wrenches may be different. The car is warmed up by driving for a distance of 10-15 km, then driven into an inspection hole or placed on an overpass.
- The engine protection is removed, the external drain plug is unscrewed and up to 0.5 liters is drained. processing into a prepared container.
- The plastic internal plug (6-sided 8-sided) is unscrewed, and up to 2.5 liters of used ATF flows out from there. In total, almost 3 liters should flow out.
- Both drain plugs are screwed in, the outer one with a new gasket. The air duct from the air filter is removed to get to the filler hole.
- The filler plug is unscrewed with a 4-pointer. Inside, through a hose and funnel, exactly 500 ml more new oil is poured than drained oil - that is, almost 3.5 liters.
- Everything is installed and screwed back on. The engine starts and warms up to operating temperature - there should be 4 oil temperature indicator marks on the dashboard indicator. Then your foot is on the brake, the selector switches, the automatic transmission operates in all gears for 10 seconds.
- To normalize the oil level in the Renault Logan box, the drain plug is unscrewed again and excess ATF flows out through it. As soon as it starts to drip, the plug is screwed back on. The protection is installed in its place.
Now you can drive further, and in a week make another similar replacement.
