Owners of concern cars Nissan, equipped with continuously variable transmissions (CVT), are often faced with the dilemma of choosing a working fluid. The official specification requires use NS-3 oils, which is radically different from previous versions NS-2 and NS-1 in terms of viscosity and additive package. Incorrect selection can lead to instant failure of the complex valve body and cones.
The oil part number often causes confusion, since the manufacturer produces packaging in different volumes and for different markets. Original Nissan Available in 1 liter and 4 liter canisters, as well as in drums for service centers. Identifying a genuine product by the code on the packaging is the only way to avoid buying a counterfeit product, which will kill the transmission within a couple of thousand kilometers.
Technical Features of the NS-3 Specification
Liquid NS-3 was developed specifically for new generations of Jatco CVTs installed on models X-Trail, Qashqai and Teana. Unlike the thicker NS-2, the new formula has a reduced viscosity at low temperatures, which makes engine starting and pump operation easier in winter. This is critical to preserving the life of the torque converter.
The key difference is the modified friction coefficient. CVT Belt drives require a precise balance between traction and slippage. NS-3 oil provides this balance, allowing the cones and belt to operate with minimal wear. Using the wrong fluid upsets this balance, causing vibration, kicking and overheating.
The manufacturer strictly regulates tolerances. If you see a mark on the canister JATCO JF011E or JF015E, this is a direct indication of compatibility with specific types of boxes. Don't try to save money by mixing different types of fluids - the chemical reaction can lead to sediment that will clog the radiator.
⚠️ Attention! The use of NS-2 oil in CVTs requiring NS-3 is strictly prohibited. This will lead to overheating and accelerated wear of the belt drive due to mismatched friction coefficient.
Explanation of article numbers and original packaging
Finding the right part number starts with understanding the coding system Nissan. The main code for 1 liter displacement is: KLE520000431 (or simplified 11000-1M50A in some catalogs). The article number is valid for a 4-liter canister KLE520000434. However, codes may vary slightly depending on the year of production, so always check the hologram on the cap.
There are many fakes on the market, so when checking the item, pay attention to the print quality and tactile sensations of the packaging. The original has clear barcodes, and the label does not come off when the engine heats up. It is important to check for a hologram with a logo Nissan, which changes color when the canister is tilted.
There are also regional specificities. In the USA, article numbers starting with 99924-1L000, which are analogous to NS-3, but may have differences in packaging. For Russian car owners, the priority remains the global codes indicated above. Buying on tap without factory markings is a huge risk.
- 🔍 Check the hologram on the lid of the canister - it should be embossed and shimmer.
- 🔍 Compare the article with data in the official catalog Nissan Parts for your model.
- 🔍 Inspect the seams canisters - the original ones are smooth, without plastic drips.
Compatible with Nissan models and Jatco CVTs
NS-3 oil is suitable for a wide range of cars manufactured after 2011-2012. Major models using this specification include Nissan Qashqai second generation (J11), Nissan X-Trail (T32) and updated versions Nissan Teana (J32). It is also used in Nissan Murano and Nissan Pathfinder with corresponding transmission versions.
It is important to understand that older models with CVTs require NS-2. Attempt to fill NS-3 into Nissan Tiida or earlier versions Qashqai (J10) can lead to a decrease in system pressure and slippage. Always check your vehicle's VIN before purchasing to ensure there is no mistake.
The table below will help you quickly determine compatibility for popular models:
| Model Nissan | Years of manufacture (approx.) | CVT type | Required fluid |
|---|---|---|---|
| Qashqai (J11) | 2014–present | Jatco JF016E | NS-3 |
| X-Trail (T32) | 2014–present | Jatco JF016E | NS-3 |
| Teana (J32) | 2012–2014 | Jatco JF011E | NS-3 |
| Qashqai (J10) | 2007–2013 | Jatco JF011E | NS-2 |
| Almera (G15) | 2012–2020 | Jatco JF015E | NS-3 |
⚠️ Attention! Changing the oil in the variator should only be done by specialized services that have equipment for accurately checking the level and pressure. An independent procedure without a scanner often leads to overfilling or underfilling.

Replacement procedure and level control
The process of changing NS-3 transmission fluid has its own nuances that distinguish it from changing engine oil. It is necessary not only to drain the old oil, but also to flush the cooling radiator and replace the coarse filter. Often, a partial replacement method is used by passing it through a machine to force out the old fluid from the torque converter.
Level control is carried out with the engine running and the gearbox warm. The oil operating temperature range should be from 50°C up to 60°C. In this case, the level should be between the marks LOW and HOT on the dipstick. If there is no dipstick, the level is checked through the inspection hole with the engine running.
For a successful replacement you will need: new NS-3 oil (volume about 4-5 liters for a complete replacement), a new filter, pan gasket and sealant. You will also need a drain plug wrench and a filling funnel. Do not forget about the need to reset the variator adaptations through the diagnostic scanner after the procedure.
☑️ Preparing for an oil change
If the oil level is below normal, the pump will begin to trap air, which will lead to cavitation and rapid wear of parts. Overfilling will cause foaming of the liquid and an increase in pressure inside the housing, which can squeeze out the seals or lead to rupture of the seals.
What happens if the variator overflows oil?
When overfilled, the oil begins to foam due to the rotation of parts, losing its lubricating properties. This causes overheating, a drop in pressure and possible failure of the valve body.
Analogues and substitutes: myths and reality
Many car owners are looking for cheaper analogues of NS-3 oil, fearing the high cost of the original. There are products from brands on the market Motul, Shell, Idemitsuwho have JATCO approval. However, even with tolerances, the chemical composition may differ from the original Nissan product.
Some services offer the use of universal "Multi CVT" fluids. For modern boxes this is an extremely risky decision. CVTs Nissan have very stringent friction requirements. Universal oils often cannot provide the required characteristics throughout the entire service interval.
If you still decide to use an analogue, make sure that the approval is clearly indicated on the canister NS-3 or Jatco JF011E/015E/016E. Avoid products without precise specifications. Never mix original NS-3 oil with any analogues, even if they have the same tolerances.
- ✅ Idemitsu CVT Fluid NS-3 - one of the best analogues, produced at partner factories.
- ✅ Motul Multi CVT - Suitable for many boxes, but requires careful tolerance checking.
- ❌ Unknown brands - Absolutely avoid oils without a clear specification.
Keep receipts and boxes of purchased oil until your next oil change. This can serve as evidence in case of a warranty claim or a dispute with the service.
Symptoms of poor quality oil or replacement errors
If after changing the oil you notice unusual sounds, vibrations or jerking when shifting gears, this is a sure sign of a problem. Perhaps the wrong type of fluid was filled in or the adaptations were not reset. CVT Jatco very sensitive to the quality of work and requires precise tuning.
A common symptom is “kicking” when moving from a place. This indicates that the coefficient of friction does not meet the requirements of the cones. The oil may be too thin or contain too few traction additives. In this case, repeated diagnostics and, possibly, replacement of the oil with the original one are required.
Also pay attention to the color of the oil. The new NS-3 has a bright red color. It will darken over time, but should not become black or cloudy. Black oil with a burning smell indicates overheating of the box and destruction of the clutches. If you see black oil after changing, it means there is already serious damage inside the box.
Regularly checking the oil level and condition is the key to a long life of the variator. Ignoring signs of trouble may cost you to replace your entire transmission.
⚠️ Attention! If the oil in the variator has acquired a black color and a burning smell, further operation of the vehicle is prohibited. Immediate diagnosis and repair of the torque converter is required.
Frequently asked questions (FAQ)
How much NS-3 oil is needed for a complete change in Nissan Qashqai J11?
A complete hardware replacement requires about 8-10 liters of fluid, since some of the oil remains in the torque converter and radiator. For a partial replacement (draining from the pan), 4-5 liters are enough.
Is it possible to mix NS-3 oil with NS-2?
Absolutely not. These fluids have different viscosities and additive packages. Mixing will lead to a change in chemical properties, sedimentation and rapid failure of the variator.
What is the oil change interval for a Nissan CVT?
Official regulations recommend replacement every 60,000 km. However, under difficult operating conditions (traffic jams, towing), it is better to reduce the interval to 40,000 km.
How to check NS-3 oil level without a dipstick?
The level is checked through the inspection hole on the gearbox with the engine running and the oil warm (50-60°C). Oil should drip from the hole, but not stream.
Where to buy original NS-3 oil?
Buy only from authorized dealers Nissan or in large, trusted online auto parts stores with a good reputation. Avoid markets and dubious sites.
