Nissan CVT Fluid NS-1: everything you need to know about CVT fluid

CVT gearboxes Nissan require special attention to the quality and condition of the transmission fluid. Nissan CVT Fluid NS-1 is a specialized oil developed by brand engineers for continuously variable transmissions Jatco, which are installed on most models Nissan, Infiniti, Renault and even Mitsubishi. Not only the smoothness of switching, but also the service life of the variator, which can exceed 250,000 km with proper maintenance.

Many car owners mistakenly believe that the fluid in the variator Nissan does not require replacement, relying on the myth of the “maintenance-free” box. However, the manufacturer clearly regulates service intervals - especially for regions with severe climatic conditions or aggressive driving styles. In this article we will look at why NS-1 better than analogues, how to check its condition yourself, and what mistakes during replacement can result in expensive repairs.

What is Nissan CVT Fluid NS-1 and for which models is it intended?

Nissan CVT Fluid NS-1 is a synthetic transmission fluid designed specifically for CVTs Jatco series JF011E, JF016E, JF017E and others. Its unique composition provides:

• 🔹 Stable viscosity at extreme temperatures (from -40°C to +150°C), which is critical for Russian winters and city traffic jams.
• 🔹 Anti-friction properties, reducing wear of the belt and variator cones by 30% compared to universal ATF.
• 🔹 Oxidation resistance, which extends the interval between replacements to 90,000 km (with moderate use).
• 🔹 Seal material compatibility, preventing leaks through the seals.

Officially NS-1 recommended for the following models Nissan (2005–2020 release):

• 🚗 Qashqai (J10, J11), X-Trail (T31, T32), Murano (Z50, Z51)
• 🚗 Teana (J31, J32), Altima (L32, L33), Maxima (A35)
• 🚗 Juke (F15), Note (E11, E12), Sentra (B17)
• 🚗 Pathfinder (R51, R52), Navara (D40) with CVT

⚠️ Attention: For CVTs Nissan 2021 and newer (For example, Ariya or Qashqai J12) liquid is used NS-3, which is incompatible with NS-1. Filling with the wrong fluid will cause the belt to slip and the box to fail.

Also NS-1 used in variators Renault (Koleos, Megane, Scenic), Mitsubishi (Outlander with JF011E) and even some Suzuki (Kizashi). However, before use, be sure to check compliance with VIN-code or manual.

Differences between NS-1 and NS-2 and NS-3: what happens if you mix them up

The manufacturer has released three generations of CVT fluids, and they cannot be interchanged. Main differences:

Parameter	NS-1	NS-2	NS-3
Year of application	2005	2012	2020
Temperature range, °C	-40…+150	-45…+160	-50…+170
Compatibility with CVTs	JF010E, JF011E, JF016E	JF016E (later versions), JF017E	JF021E, JF022E (hybrids)
Color	Green	Blue	Red
Replacement interval (thousand km)	60–90	80–100	100–120

If you fill NS-2 instead of NS-1, the consequences will not appear immediately, but after 10–15 thousand km the following may occur:

• 🔴 Increased belt wear due to a different formula of anti-wear additives.
• 🔴 Slippage during sudden accelerations (especially at Qashqai J10 And X-Trail T31).
• 🔴 Solenoid contamination, leading to jerking when switching.

⚠️ Attention: Services often offer “universal” liquids (for example, Idemitsu CVTF or Ravenol CVT) as a replacement NS-1. However, the original fluid contains a unique additive package Nissan Matic Fluid Technology, which is not reproduced by analogues. It’s not worth the risk - savings of 1,500 rubles can result in repairs costing 150,000 rubles.

When and how often to change NS-1: regulations and signs of wear

Official regulations Nissan for NS-1 provides for replacement every 90,000 km or once every 6 years (whichever comes first). However, these figures are relevant for ideal conditions:

• 🌡️ Ambient temperature from -20°C to +30°C.
• 🛣️ Smooth driving style without sudden starts.
• 🏙️ No long traffic jams (variator overheating).

In the realities of Russian operation, the interval is reduced to 60,000 km, and in some cases up to 40,000 km:

• 🔥 Aggressive riding (frequent kickdowns, towing a trailer).
• ❄️ Extreme frosts (below -30°C) or heat (above +35°C).
• 🚗 Taxi/car sharing - increased load on the box.
• 🛑 Frequent short trips (the oil does not have time to warm up).

Signs that it’s time to change the NS-1:

• 🔴 Jerks when accelerating or braking the engine.
• 🔴 Burning smell from liquid (checked with a dipstick).
• 🔴 Dark color (black or brown instead of green).
• 🔴 Hum or vibration from the variator side at idle.
• 🔴 Error P17F0 (box overheating) on the dashboard.

Step-by-step instructions for replacing NS-1 with your own hands

Replacement Nissan CVT Fluid NS-1 in garage conditions requires accuracy and adherence to technical procedures. You will need:

• 🔧 New fluid (8–12 liters for a complete replacement).
• 🔧 Variator filter (article 31726-1XF0A for most models).
• 🔧 Pan O-ring (31397-1XF0A).
• 🔧 Head set (10 mm, 14 mm) and a torque wrench.
• 🔧 Funnel with narrow spout and a filling hose.

Work order:

1. Warm up the box up to 50–60°C (drive 10–15 km). This will reduce the viscosity of the fluid for complete drainage.
2. Drain the old oil:
   • Place a container with a volume of at least 6 liters.
   • Unscrew the drain plug (14 mm wrench) and let the liquid drain (10–15 minutes).
   • Remove the pan (12 x 10mm bolts) and drain the residue.
3. Replace the filter:
   • The filter is secured with 3 bolts. When removed, another ~0.5 liters of liquid may leak out.
   • Install a new filter and pan o-ring.
4. Rinse the tray:
   • Remove metal shavings from the magnets (their presence is normal, but a large amount indicates wear).
   • Wipe the tray with a lint-free cloth dampened in NS-1.
5. Filling with new fluid:
   • Screw in the drain plug with a new sealing ring (tightening torque 35 Nm).
   • Fill with fresh NS-1 through the probe hole (~7.5 liters will be required for partial replacement).
   • For complete replacement repeat the drain-fill procedure 2-3 times with intermediate trips.

Critical errors when replacing:

• ❌ Underfilling or overfilling liquid (optimal level is between MIN And MAX on the dipstick when the box is warm).
• ❌ Using sealant instead of the pan sealing ring (will lead to clogging of the solenoids).
• ❌ Replacement without flushing in case of severe contamination (residues of old oil reduce the service life of the new one).

What to do if jerking appears after replacement?

If after replacement NS-1 The variator began to twitch, the reasons may be as follows:

1. Incorrect fluid level - check with a probe on a warm box (engine is running, selector is in P).

2. Airing the system — several cycles of heating and cooling the box are required.

3. Liquid defect - original NS-1 has a green tint and a specific smell (not mustard!).

4. Solenoid wear — if there were jerks before replacement, valve diagnostics may be required.

To fix, pump the fluid: 10 minutes drive alternating modes D And R in place (by pressing the brake!).

How to check the level and condition of NS-1 without visiting a service center

Level and quality control Nissan CVT Fluid NS-1 - a simple procedure that you can do yourself. Important: verification is carried out only on warm box (liquid temperature 50–80°C).

Verification algorithm:

1. Start the engine and let it run for 5-10 minutes (or drive 10 km).
2. Place the car on a flat surface and move the selector to position P.
3. Remove the variator dipstick (usually yellow, located next to the battery).
4. Wipe the dipstick with a lint-free cloth, reinsert it, and remove it again.
5. Assess the level: it should be between the marks MIN And MAX in the zone HOT.

Fluid condition assessment:

Parameter	Norm	Needs replacement
Color	Transparent green	Dark brown or black
Smell	Neutral or weak chemical	Burnt (resembles burnt rubber)
Consistency	Liquid, without suspension	Thick, with metal shavings or flakes
Foam	Missing	Present (indicates air or water ingress)

For more accurate diagnosis, you can use test strips (For example, Nissan CVT Fluid Checker), which determine:

• 🔬 Acid number (TAN) — an increase above 2.5 mg KOH/g indicates oxidation.
• 🔬 Content of wear products (iron, copper, aluminum).
• 🔬 Viscosity — deviation from 30–35 mm²/s at 100°C.

Original vs analogues: what to fill if you don’t have NS-1

Original liquid Nissan CVT Fluid NS-1 (article KE909-99932) costs about 1,200–1,500 ₽/liter, which makes its replacement quite expensive. However, saving on analogues may result in repairs. If the original is not available, you can use certified substitutes:

Manufacturer	Title	Article	Compatibility	Notes
Idemitsu	CVT Fluid	30450-54F	Full	Nissan approved, used on assembly line
Ravenol	CVT Fluid NS-1	4014835755457	Full	High thermal stability, suitable for turbocharged engines
Mitsubishi	DiaQueen CVT Fluid J1	MZ320266	Partial	Only for CVTs JF011E until 2012
Febi	CVT Fluid	32600	Full	German quality, but difficult to find in Russia

What should not be put into the variator? Nissan:

• ❌ ATF for automatic transmission (For example, Dexron VI or Toyota T-IV) - different viscosity and additive package.
• ❌ Universal CVT fluids without approval Nissan (For example, Castrol Transmax CVT).
• ❌ Fluids for torque converters (For example, ZF Lifeguard).
• ❌ NS-2 or NS-3 in boxes where required NS-1.

⚠️ Attention: If you are forced to top up with analogue, never mix different liquids! Perform a complete replacement with flushing as soon as possible. Mixing NS-1 And NS-2 leads to the formation of gel-like deposits that clog the solenoids.

Where to buy the original NS-1:

• 🛒 Official dealers Nissan - guarantee against counterfeiting, but the price is higher than the market.
• 🛒 Verified online stores (For example, Exist.ru, Autodoc) - look for reviews about the seller.
• 🛒 Specialized services for CVTs - they often sell the fluid with a guarantee.

If you found NS-1 cheaper than 1,000 ₽/liter, it’s 100% fake. The original liquid is supplied in sealed cans with a hologram and production date on the bottom.

Top 5 errors that kill the variator after replacing the NS-1

Even if you uploaded the original Nissan CVT Fluid NS-1, incorrect actions after replacement can reduce the life of the box. Common mistakes:

1. Ignoring CVT adaptation

   After replacing the fluid, the box needs to “learn” new friction properties. If adaptation is not performed, kicks may occur when switching. How to do:

   1. Прогреть коробку до 60°C.
   2. Нажать тормоз и поочерёдно включать режимы P→R→N→D→L с задержкой 5 секунд.
   3. Проехать 10–15 км в щадящем режиме (без кикдаунов).

2. Excess liquid level

   Excess NS-1 leads to foaming of the oil, which disrupts the operation of the valve body. Symptoms: box hum, jerking when braking. Level is checked only on a warm box!

3. Using washes

   Flushing fluids (e.g. Liqui Moly CVT Reiniger) aggressive to variator seals Nissan. If cleaning is required, use only NS-1 for washing (3–4 drain-fill cycles).

4. Replacement without resetting the oil aging counter

   The CVT control unit (TCU) keeps track of mileage and operating conditions. After replacement NS-1 The counter must be reset via a diagnostic scanner (for example, Launch X431 or Nissan Consult). Without a reset, the box will “think” that the oil is old and incorrectly adjust the pressure.

5. Saving on filter

   Variator filter (31726-1XF0A) costs ~1,500 ₽, but its replacement is required at every maintenance. A clogged filter leads to oil starvation and belt wear. Signs of a clogged filter: pump hum, delay when switching to "D".

📊Have you ever encountered variator problems after changing the oil?

• Yes, there were jerks
• Yes, the box is faulty
• No, everything went smoothly
• I didn't change the oil myself

FAQ: Frequently asked questions about Nissan CVT Fluid NS-1

Is it possible to mix NS-1 with NS-2 if there is not enough to top up?

No! These fluids have different chemical compositions and additive packages. Mixing will lead to the formation of sediment, which will clog the solenoids and accelerate belt wear. As a last resort, add NS-1 only or change the oil completely.

What volume of NS-1 is needed for a complete replacement?

Volume depends on model:

• Qashqai J10/J11, X-Trail T31/T32 — 7.8–8.2 l.
• Teana J31/J32, Murano Z50 — 9.5–10 l.
• Juke F15, Note E11 — 6.5–7 l.

For complete replacement 12–15 liters will be required (3–4 drain-fill cycles).

What will happen if you don’t change NS-1 at all?

Refusal to replace leads to:

• 🔥 Overheating of the box (the liquid loses its heat-removing properties).
• 🔥 Belt slippage (additive wear → reduction in friction properties).
• 🔥 Bullies on cones (metal shavings act as an abrasive).
• 🔥 Solenoid failure (contamination with wear products).

Average variator resource without oil change - 120,000–150,000 km (instead of 250,000+ km during maintenance).

How to distinguish the original NS-1 from a fake?

Signs of the original liquid:

• 🟢 Canister with hologram and production date on the bottom.
• 🟢 Color - transparent green (not red and not blue!).
• 🟢 The smell is weak chemical, without a burnt shade.
• 🟢 The product number is indicated on the label KE909-99932 and inscription "Genuine Nissan CVT Fluid NS-1".
• 🟢 When shaken, the foam settles in 5-10 seconds.

Counterfeits often have a cloudy color, a pungent odor and are sold in canisters without holograms.

Can NS-1 be used in CVTs of other brands (Toyota, Honda)?

No. CVTs Toyota (K311/K313) and Honda (Honda HMMF) require specialized liquids with different viscosity characteristics and additive package. Fill NS-1 into these boxes will lead to:

• ❌ Belt slippage (for Toyota
