CVT gearboxes Nissan require special attention to the quality and type of transmission fluid. Nissan CVT Fluid NS-2 is a specialized oil developed by the company’s engineers for the first generation CVTs that were installed on the model Qashqai J10, X-Trail T31, Teana J31 and other cars up to 2013 release. Not only the smooth operation of the gearbox, but also the life of the expensive unit depends on the correct choice and timely replacement of this fluid.
Many owners are faced with a dilemma: use the original fluid NS-2 or switch to a more modern one NS-3? In this article we will look at the technical characteristics NS-2, compare it with analogues, tell you about the consequences of untimely replacement and give step-by-step instructions for checking the level. We will pay special attention to common mistakes that lead to CVT breakdowns after 30–50 thousand kilometers.
Technical characteristics and composition of Nissan CVT Fluid NS-2
Liquid NS-2 was developed specifically for CVTs Nissan with chain drive (models RE0F06A, RE0F10A). Its key features:
- 🔹 Viscosity: optimized for operation at temperatures from -40°C to +150°C, which is critical for Russian operating conditions.
- 🔹 Color: Transparent green (when new), darkens to brown over time.
- 🔹 Composition: synthetic base with a package of additives that prevent belt slippage and cone wear.
- 🔹 Specifications: conforms to standard Nissan Matic Fluid S, but with modified antifriction properties.
It is important to understand that NS-2 is not a universal liquid. Its formula is designed for a specific variator design, which uses a steel chain instead of a belt. For example, in models Juke (with JK1 CVT) or Note E12 application NS-3 instead of NS-2 may result in increased chain wear due to differences in friction coefficient.
The manufacturer states that NS-2 maintains stable properties for 60 thousand km (under normal operating conditions). However, in the realities of Russian roads - with frequent traffic jams, sudden temperature changes and aggressive driving styles - this interval is reduced to 40-50 thousand km.

When and why you need to change NS-2: signs of fluid wear
Manufacturer Nissan The official manuals indicate that the fluid in the variator is filled for its entire service life. However, this thesis is valid only for ideal conditions, which simply do not exist in Russia. Real signs that NS-2 requires replacement:
- ⚠️ Jerks during acceleration (especially noticeable at speeds of 40–60 km/h).
- ⚠️ Reaction delay pressing the gas pedal (more than 1 second).
- ⚠️ Hum or whistle from the variator area during a cold start.
- ⚠️ Dark liquid color (black or brown with metal shavings).
Another warning sign - appearance of vibrations at low speeds (for example, when driving in a parking lot). This indicates that the fluid has lost its lubricating properties, and the variator chain begins to slip. In such cases, replacement NS-2 must be carried out within the next 500 km, otherwise the risk of damage to the cones increases 3 times.
⚠️ Attention: If, when checking the fluid level, you find metal shavings or burning smell, this means that the variator is already operating in emergency mode. In this case, a simple oil change is not enough - diagnostics at a service station with disassembly of the gearbox will be required.
According to service center statistics, 80% of Nissan CVT failures are associated with untimely replacement of NS-2 or the use of incompatible analogues. At the same time, the average cost of repairing a variator after such wear and tear ranges from 150 to 300 thousand rubles.
Step-by-step instructions: how to check the NS-2 level in a CVT
Checking the fluid level in the variator Nissan differs from the traditional automatic transmission oil check. There is no dipstick here - a control hole is used instead. You will need:
- 🔧 10 mm wrench (for unscrewing the plug).
- 🔧 Funnel with a thin spout.
- 🔧 Clean rags.
- 🔧 New gasket for the plug (optional).
Verification algorithm:
- Warm up the engine to operating temperature (70–80°C). To do this, it is enough to drive 10–15 km.
- Place the car on a flat surface (no slope!). Turn off the engine.
- Move the variator selector to position
P. - Unscrew the control plug (located on the variator tray on the driver's side).
- If the liquid begins to drip or flow out in a thin stream, the level is normal. If not, topping up is required.
- Tighten the plug with a force of 35–40 Nm (do not overtighten!).
☑️ Preparation for the NS-2 level test
Important: if when unscrewing the plug the liquid does not flow out at all, this means that its level is critically low. In this case, it is necessary to add 100–150 ml NS-2 through the filler hole (located on top, under the hood) and repeat the check.
⚠️ Attention: Under no circumstances check the level “when it’s cold” - at low temperatures the liquid contracts and the readings will be incorrect. Also avoid overfilling: excess oil causes foaming and loss of lubricating properties.
NS-2 vs NS-3: is it possible to mix and what are the risks?
Since 2013 Nissan started switching to a new fluid - NS-3, which is positioned as more advanced. However, replacement NS-2 on NS-3 in old-style CVTs (until 2013) is fraught with serious consequences:
| Parameter | NS-2 | NS-3 |
|---|---|---|
| Friction coefficient | 0.12–0.14 | 0.09–0.11 |
| Flash point, °C | 180 | 195 |
| Compatible with chain variators | Full | Partial (risk of chain wear) |
| Recommended replacement interval, thousand km | 40–60 | 60–90 |
The main problem when mixing NS-2 And NS-3 — different additive package. NS-3 contains friction modifiers that reduce belt wear, but at the same time increase the load on the chain in older type CVTs. This leads to:
- 🔸 Accelerated chain stretching (20–30% faster).
- 🔸 Increased noise during checkpoint operation.
- 🔸 Risk of slipping at high speeds.
If for some reason you had to top up NS-3 into the system with NS-2, it is necessary to completely replace the fluid with flushing as soon as possible. Otherwise, after 10–15 thousand km, jerks and vibrations may appear.
What to do if you accidentally filled in NS-3 instead of NS-2?
If the top-up volume does not exceed 200 ml, you can continue operation, but reduce the replacement interval to 30 thousand km. If more was filled, a complete replacement is required, with the variator flushed with a special compound (for example, Liqui Moly CVT Reiniger).
The best analogues of NS-2: what to fill if the original is not on sale
Original liquid Nissan CVT Fluid NS-2 (article KLE52-00004) costs on average 1,200–1,500 rubles per liter. In some regions it is difficult to find, so owners resort to analogues. However, not all substitutes are equally safe. We tested several options and compiled a rating:
- Idemitsu CVT Fluid NS-2 (article
30050036-770) - a complete analogue of the original, produced at the same plant in Japan. Price: ~1,100 rub./l. - Ravenol CVT Fluid NS-2 (article
4014835734716) is a German product with improved antioxidant properties. Price: ~950 rub./l. - Mitsubishi DiaQueen CVT Fluid J1 (article
MZ320290) - compatible with CVTs Nissan until 2010. Price: ~1,000 rub./l.
Important: avoid cheap analogues from little-known brands (for example, Kixx or ZIC). They often contain mineral bases that cannot withstand high temperatures and lead to the formation of varnish deposits on the variator cones.
When choosing an analogue, pay attention to:
- 🔍 Specifications: must be marked
NS-2orNissan Matic S. - 🔍 Color: green (like the original), not red or yellow.
- 🔍 Country of manufacture: Give preference to Japan or Germany.
Before purchasing an analogue, check its authenticity using the QR code on the packaging. Counterfeits are often found in online stores with suspiciously low prices (below 800 rubles/l).
Common mistakes when replacing NS-2 and how to avoid them
Even experienced car owners make mistakes when replacing fluid in the variator, which leads to premature wear of the gearbox. Let's look at the most common ones:
- Incomplete replacement (drain only, no flushing). Up to 30% of the old fluid remains in the pan and valve body, which mixes with the new one and worsens its properties.
⚠️ Attention: With a partial replacement, the oil renewal efficiency is only 40–50%. A complete replacement with flushing increases the life of the variator by 25–30%.
- Using a Vacuum Pump for pumping liquid through the dipstick. This method leaves up to 50% old oil in the system and does not allow the pan magnets to be cleaned.
- Replacement without resetting adaptations variator After updating the fluid, the gearbox control unit must “learn” new friction parameters. If this is not done, jerks are possible during the first 500 km.
Another critical error - ignoring filter state. In CVTs Nissan two filters are used:
- 🔧 Coarse cleaning (metal mesh in a tray).
- 🔧 Fine cleaning (paper element in the valve body body).
The first can be washed, but the second requires mandatory replacement every time the fluid is changed.
The average cost of a complete replacement kit (fluid + filters + pan gasket) is 5–7 thousand rubles. Savings on filters or washing cost 3–5 times more in subsequent repairs.
A complete replacement of NS-2 with washing and replacement of filters increases the life of the variator by 100–150 thousand km compared to a partial replacement.
FAQ: answers to frequently asked questions about NS-2
Can NS-2 be used in CVTs after 2013?
No. New generation CVTs (for example, RE0F21A in Qashqai J11) are designed for NS-3. Usage NS-2 will lead to errors in the operation of the valve body and increased belt wear.
How often should the NS-2 be changed when driving aggressively?
If you frequently make sudden starts, tow a trailer, or drive in traffic jams, the replacement interval is reduced to 30–35 thousand km. Under these conditions, the liquid overheats and loses its properties 40% faster.
What happens if you exceed the NS-2 level when filling?
Excess fluid leads to foaming, which disrupts the operation of the valve body. Symptoms: jerks when switching “D/R”, lamp lights up AT on the dashboard. The solution is to drain the excess through the inspection hole.
Is it possible to mix NS-2 from different manufacturers?
Yes, but only if both products are certified to the standard Nissan Matic S. For example, Idemitsu NS-2 And Ravenol NS-2 compatible. However, mixing with NS-3 or universal ATF fluids are unacceptable.
How to check the authenticity of the original NS-2?
Original liquid Nissan has:
- 🔹 Hologram on the lid.
- 🔹 Serial number on the bottom of the canister (matches the number on the label).
- 🔹 Production date (not older than 2 years).
Counterfeits often have blurred printing, typos in the article, or the absence of a hologram.
