CVT Nissan Murano Z50 (2009–2014) - one of the most reliable in the line of the Japanese brand, but only with proper maintenance. The main enemy of the continuously variable transmission is overheating and oil contaminationwhich lead to jerking, slipping and expensive repairs. Owners often wonder what kind of oil to pour into the variator Murano Z50, is it possible to use analogues instead of the original one? NS-2, and how often should I change it?

In this article we will analyze all the nuances: from the official requirements of the manufacturer to the real experience of car owners. You'll find out why Changing the oil in the Murano Z50 variator every 60 thousand km is not a whim, but a necessity, even if the service book says otherwise. We will also consider common replacement errors that reduce CVT life by 30–40%.

Official Nissan requirements: what oil to fill in the Murano Z50 CVT

The manufacturer clearly indicates: for CVT Jatco JF011E, installed on Murano Z50 with engines VQ35DE (3.5 l) and QR25DE (2.5 l), must be used only original liquid Nissan CVT Fluid NS-2. This oil is designed specifically for chain-driven CVTs where the following is critical:

  • 🔹 Stable viscosity at high temperatures (up to +120°C in severe conditions).
  • 🔹 Anti-friction additives, reducing wear on the chain and cones.
  • 🔹 Seal material compatibility (rubber, fluoroplastic).

Article number of the original oil: KLE52-00004 (4 liters) or KLE52-00001 (1 liter). Important: NS-2 not compatible with earlier version NS-1 and later NS-3! Using the wrong fluid will lead to accelerated chain wear and loss of pressure in the valve body.

📊 What oil do you use in the Murano Z50 CVT?
  • Original NS-2
  • Analogue (Idemitsu, Ravenol)
  • Other
  • I don't know what's in there

In the manual Nissan it is indicated that the fluid is in the variator Murano Z50 designed for entire service life (so-called "lifetime oil"). However, this is only true for ideal operating conditions: moderate climate, no towing, smooth driving style. In reality, even in Europe, dealers recommend replacement every 60–90 thousand km, and in Russia and the CIS countries - every 40–50 thousand km.

Analogues of NS-2: is it possible to fill in non-original oil?

Original oil NS-2 is expensive (from 1,200 rubles/liter), so many owners are looking for analogues. It is important to understand: not every CVT fluid is suitable for JF011E. There are two selection criteria:

  1. Specification Compatibility: oil must be approved Nissan NS-2 or Jatco JF011E.
  2. Base quality: full synthetic only (group V via API).

Proven analogues that use services:

  • 🛢️ Idemitsu CVT Type-N (article 30050045-760401) - the closest in composition to the original.
  • 🛢️ Ravenol CVT Fluid J1F011E (article 4014835735807) - German quality, often cheaper than the original.
  • 🛢️ Mobil CVT Fluid (article 153652) - universal, but requires more frequent replacement.
💡

Before purchasing an analogue, check for approval NS-2 on the canister. If it is not there, you risk getting foam in the oil and loss of pressure in the valve body.

⚠️ Attention: Do not mix under any circumstances NS-2 with other liquids, even if they are positioned as “universal”. Chemical reaction between additives can lead to clogged solenoids and variator failure. If you don’t know what was uploaded earlier, do it complete replacement with flushing.

Replacement frequency: when to change the oil in the Murano Z50 variator

Official regulations Nissan for Murano Z50 does not provide for changing the oil in the variator, but this gross mistake. Practice shows that ignoring replacement leads to the following problems:

  • 🚨 Jerks during acceleration (especially when “cold”).
  • 🚨 Switching delays between "D" and "R".
  • 🚨 Hum or vibration at speeds of 40–60 km/h.
  • 🚨 CVT overheating (temperature above 110°C).

Recommended replacement intervals depending on operating conditions:

Operating conditions Replacement interval Replacement type
Moderate climate, city driving 60,000 km Partial (30–40%)
Hot climate, frequent traffic jams 40,000 km Full (hardware)
Towing, off-road, aggressive driving 30,000 km Complete + filter replacement
Taxi, commercial operation 25,000 km Full + flush

⚠️ Attention: If the variator is already “kicking” or giving an error P0776 (pressure solenoid malfunction), A complete oil change may make the problem worse. In this case, diagnostics of the valve body and circuit is first required.

Check the oil level (should be between "HOT" and "COLD" on the dipstick)

Buy 12 liters of oil for a complete change (or 4–5 liters for a partial change)

Prepare a new variator filter (part number 31726-1XF0A)

Warm up the variator to operating temperature (drive 10–15 km) -->

Step-by-step instructions: how to change the oil in a variator yourself

Changing the oil in the variator Murano Z50 more difficult than in an automatic transmission due to design features JF011E. You will need:

  • 🔧 Special key for drain plug (24 mm high profile).
  • 🔧 Oil injection syringe (or a funnel with a flexible tube).
  • 🔧 Diagnostic scanner to reset the oil aging counter (if any).

Step 1. Drain the old oil

  1. Start the engine, warm up the variator to 60–70°C (check OBD-II or thermometer).
  2. Raise the vehicle on a lift or ramp.
  3. Unscrew the drain plug (the tightening torque for reinstallation is 35 Nm).
  4. Drain the oil into a container (~5–6 liters will leak out during partial replacement).

Step 2: Replace the filter (with complete replacement)

Variator filter Murano Z50 located inside the housing and requires removal of the tray. Be careful: when removing the pan, additional oil may leak out (up to 1 liter). Pan sealing gasket (article no. 31397-1XF0A) be sure to replace — reuse is fraught with leaks.

Step 3. Filling with new oil

  1. Screw on the drain plug with a new washer (part no. 11026-01M02).
  2. Fill the oil through the filler hole (located to the right of the battery, under the plastic cover).
  3. Volume for partial replacement: 5–5.5 liters (to the "COLD" level on the dipstick).
  4. For a complete replacement you will need 10–12 liters and hardware displacement of old fluid.
How to reset the oil aging counter?

To reset the counter via OBD-II use a scanner with support Nissan Consult or program CVTz50 Reset Tool. Algorithm:

1. Connect the scanner to the diagnostic connector.

2. Select the "Transmission" block.

3. Find the "Fluid Deterioration Data" parameter and reset it to zero.

Without a reset, the CVT ECU will consider the oil to be “old”, which will lead to incorrect adaptation of the gear ratios.

Common mistakes when changing oil and their consequences

Even experienced craftsmen make mistakes that reduce the life of the variator Murano Z50. Here are the most critical ones:

  1. Incomplete drainage of old oil. With a partial replacement, up to 40% of waste remains in the system, which mixes with the new fluid and accelerates its oxidation. Solution: Use the "double change" method (drain and fill at 500 km intervals).
  2. Using the wrong oil. For example, NS-3 instead of NS-2 leads to chain slippage due to different viscosity. Solution: Check the tolerances on the canister.
  3. Overfilling or underfilling oil. A level above "HOT" on the dipstick leads to foaming, below "COLD" - to oil starvation. Solution: check the level when the variator is warm (oil temperature 50–60°C).
  4. Ignoring filter replacement. A clogged filter increases the pressure in the system, which leads to rupture of seals valve body Solution: change the filter every 60 thousand km.

⚠️ Attention: If, after changing the oil, the variator begins to “twitch” at low speeds, the likely cause is incorrect ECU adaptation. Solved by resetting adaptations through a diagnostic scanner ("CVT Relearn" procedure).

💡

The most common mistake is saving on oil. Cheap analogues (for example, Lukoil CVT) do not withstand loads and after 20 thousand km they lose their properties, which leads to chain wear 30–50% faster.

Signs of oil wear: when an unscheduled replacement is required

Even if you follow the regulations, sometimes the oil in the variator Murano Z50 requires early replacement. Pay attention to the following symptoms:

  • 🔴 Oil color: If the fluid on the dipstick is dark brown or black, change it immediately. Normal color - reddish-transparent.
  • 🔴 Burning smell: indicates overheating and degradation of additives. Often accompanied by an error P0715 (input shaft speed sensor malfunction).
  • 🔴 Metal shavings on the drain plug magnet: a sign of chain or bearing wear.
  • 🔴 Foam on dipstick: indicates air has entered the system (often due to low oil level).

If at least one of these signs is detected, don't delay replacement. Delay is fraught with:

  • 💥 Open circuit variator (repair from RUB 150,000).
  • 💥 Scratches on the cones (requires replacement of the variator assembly).
  • 💥 Valve unit failure (cleaning solenoids will cost 30–50 thousand rubles).

To check the condition of the oil you can use express test:

  1. Drop the oil from the dipstick onto a white paper towel.
  2. Wait 5 minutes: if the stain has clear edges and a reddish tint, the oil is normal. Fuzzy edges and dark color - need replacement.

Answers to frequently asked questions (FAQ)

Can I use NS-3 oil instead of NS-2 in Murano Z50?

No! NS-3 has a different viscosity characteristic and is designed for CVTs JF016E/JF017E (For example, Nissan Qashqai J11). B JF011E it causes chain slippage and accelerated wear of the cones. Use only NS-2 or certified analogues.

How much oil is needed for a complete change in the Murano Z50 CVT?

For complete hardware replacement will be required 10–12 liters (depending on the degree of contamination of the system). With a partial replacement (drain-fill), it takes ~5 liters. Important: after a hardware replacement, check the oil level after 500 km - topping up may be necessary.

How to check the oil level in the Murano Z50 CVT?

Verification algorithm:

  1. Warm up the variator to 50–60°C (drive 10–15 km).
  2. Place the car on a level surface.
  3. With the engine running, move the selector through all positions (P-R-N-D) with a delay of 5 seconds.
  4. Return to position "P" and check the level on the dipstick - it should be between the "HOT" marks.

⚠️ Attention: On a cold variator, the level will be higher than the real one (up to the “COLD” mark), but this does not mean that there is enough oil!

What happens if you don’t change the oil in the variator?

The consequences depend on the mileage:

  • 100–150 thousand km: jerks during acceleration, increased fuel consumption (up to +1.5 l/100 km).
  • 150–200 thousand km: slippage, errors P0730, P0776, overheating of the variator.
  • 200+ thousand km: broken chain, scuffed cones, complete CVT failure (repair ~200,000 RUR).

In 80% of cases the variator Murano Z50 "dies" precisely because of the oil. Regular replacement (every 40–60 thousand km) increases the CVT resource to 300–400 thousand km.

Is it necessary to flush the variator when changing the oil?

Flushing is required in two cases:

  1. If the oil has not been changed for more than 100 thousand km.
  2. If chips are found in the old fluid or it has a burning smell.

For rinsing use special flushing oil (For example, Liqui Moly CVT Spulung) or method double replacement (drain and fill at intervals of 500 km). Do not use automatic transmission washes under any circumstances - they are aggressive to the rubber seals of the variator!
