CVT Nissan Murano Z51 - one of the most reliable in the line of the Japanese brand, but only with competent service. Many owners mistakenly believe that continuously variable transmission does not require oil changes, or they do it too rarely, focusing on the “indestructible” status of the CVT. In practice ignoring the regulations for changing the oil in the variator Murano Z51 leads to belt slipping, overheating and expensive repairs already within 150–200 thousand km.

This article is not just instructions, but step-by-step guide with nuances, which you will not find in standard manuals. We will look at: when exactly to change the oil (spoiler: more often than the dealer says!), what kind of oil to pour into Jatco JF011Ehow to check its condition without a trip to the service center, and why partial replacement is a half measure. You will also find out what errors lead to the failure of the variator within 30–50 thousand km after improper maintenance.

Why CVT Murano Z51 sensitive to oil: technical features

CVT Jatco JF011E, installed on Nissan Murano Z51 (2015–2026), fundamentally different from classic automatic transmissions. Instead of planetary gears, it is used here variable section steel belt, which transmits torque through two cone pulleys. The oil in such a unit performs three critical functions:

  • 🔥 Heat dissipation — the variator heats up more than the automatic transmission due to constant friction of the belt on the pulleys. Overheating by 10–15°C reduces the oil life by 2 times.
  • ⚙️ Bearing lubrication - in JF011E Up to 12 bearings are used, which wear out within 5–10 thousand km without oil.
  • 🧲 Power transmission — the oil creates hydraulic pressure to compress the pulleys. If it loses viscosity, the belt begins to slip.

The main problem is additive degradation. Over time, the oil oxidizes, forming varnish deposits on the pulleys and clogging the valve body solenoids. B Murano Z51 this shows up:

  • ⚠️ Jerky during acceleration (especially when “cold”).
  • 📉 RPM dips when switching modes D ↔ R.
  • 🔊 Noise from under the hood at speeds of 60–90 km/h.

The manufacturer claims that the oil in the variator JF011E “filled for the entire service life”, but this is marketing. In practice even synthetic oil NS-3 loses properties after 60–80 thousand km, and with aggressive driving or towing - already by 40–50 thousand km.

📊 How often do you change the oil in your variator?
  • Every 40–60 thousand km
  • Every 80–100 thousand km
  • Only when problems arise
  • Never changed
  • I don't know what's in there

When to change the oil: regulations vs reality

Official regulations Nissan for Murano Z51 prescribes check the oil every 30 thousand km, and replacement - “if necessary”. In practice, this means that dealers rarely remind you to service the CVT until it starts to “kick.” Experts and technicians with experience in CVT repair recommend other intervals:

Operating conditions Replacement interval (thousand km) Replacement type
Quiet ride, city/highway 50/50 60–70 Partial (30–40% volume)
Aggressive style, frequent acceleration 40–50 Full (hardware or manual)
Towing, off-road, heat (+30°C) 30–40 Full + flush
Taxi, commercial operation 25–30 Complete + filter replacement

How to determine when it's time to change the oil right now? Here 5 signs of critical wear:

  1. The color of the oil on the dipstick has become dark brown or black (the norm is light amber).
  2. Burning smell or burnt metal when checking the level.
  3. Visible on the dipstick metal particles (chips, dust).
  4. CVT "stupid" when switching from P on D (delay >1 sec).
  5. Can be heard when cold grinding or whistling from under the hood.
⚠️ Attention: If the oil is in the variator Murano Z51 became cloudy with a whitish tint, this is a sign of antifreeze entering through a damaged heat exchanger gasket. In this case it is required complete disassembly of CVT - A simple oil change is not enough.

What kind of oil to pour into the variator Nissan Murano Z51: original vs analogues

CVT manufacturer Jatco strictly regulates the use only specialized oils for CVT. B Murano Z51 with motors VQ35DE (3.5 l) and QR25DE (2.5 l) officially recommended:

  • 🔹 Nissan CVT Fluid NS-3 (art. KLE52-00004) - original, optimized for JF011E.
  • 🔹 Mitsubishi CVT Fluid J4 - complete analogue NS-3, but 20–30% cheaper.

Can other oils be used? Theoretically yes, but with reservations:

  • ✅ Acceptable analogues: Idemitsu CVTF, Ravenol CVT, Motul Multi CVT - only if they are certified according to the standard JASO-1A.
  • ❌ Prohibited oils: DEXRON VI, ATF for automatic transmissions, universal transmission oils. Their viscosity is not suitable for working with steel belts.

Oil volume in the variator Murano Z51:

  • 🔧 Partial replacement: 4–5 liters (~30–40% of the total volume is drained).
  • 🔧 Full replacement: 9–10 liters (including rinsing).
💡

Before purchasing oil, check its authenticity! Fake NS-3 often sold in plastic canisters without a hologram. The original is always in a metal container with laser markings on the bottom.

Preparing for replacement: tools and consumables

To change the oil in the variator yourself Murano Z51 you will need:

Fresh oil NS-3 (10 l for a complete replacement)|New variator filter (art. 31726-31X0A)|Pan gasket (art. 31397-31X00)|10 mm wrench and 14 mm socket|Funnel with long spout (for pouring through dipstick)|Drain container (minimum 5 l)|Clean, lint-free rags|Torque wrench (for pan bolts)-->

Pay special attention filters. In the variator JF011E there are two of them:

  1. Coarse filter (metal mesh in the tray) - can be washed and reinstalled.
  2. Fine filter (paper, inside the case) - be sure to replace, even if it looks clean on the outside.

Also prepare flushing fluid (For example, Liqui Moly CVT Reiniger), if you are planning a complete replacement. It removes varnish deposits from pulleys and solenoids.

⚠️ Attention: Do not use Karcher or alkaline-based detergents to clean the tray! They destroy the gasket and leave micro-scratches on the magnets, which will then become sources of chips.

Step-by-step instructions: how to change the oil in a variator Murano Z51

The process of changing the oil in the variator Nissan Murano Z51 consists of 5 stages. We'll sort it out complete replacement (the most effective method), but if you don’t have the time or tools, you can limit yourself to partial.

Step 1: Drain the old oil

1. Warm up the engine to operating temperature (70–80°C) and turn off.

2. Raise the car on a lift or drive it into a pit. Remove the crankcase protection (if equipped).

3. Place a container under the variator drain plug (it is located to the right of the pan).

4. Unscrew the plug with a 14 mm wrench and drain the oil. Inspect it carefully for metal shavings.

5. After draining, unscrew the pan bolts (14 pieces) and carefully remove it. Be prepared for another ~0.5 liters of oil to leak out.

Stage 2: Cleaning the pan and replacing filters

1. Clean the pan of old sealant and deposits. Pay special attention to magnets - they must be clean and without chips.

2. Remove the coarse filter (fastened with 3 bolts), wash it in gasoline or a special cleaner.

3. Replace the fine filter (located inside the variator, you need to remove the cover).

Stage 3: Flushing the variator

For a complete replacement, you will need a washer, but you can do without it:

1. Fill in 3–4 liters of new oil through the dipstick.

2. Start the engine and alternately switch the variator selector (P → R → N → D) with a delay of 5–10 seconds in each position.

3. Stop the engine and drain the flushing oil. Repeat the procedure 2-3 times until the drained liquid turns light.

Step 4: Filling with new oil

1. Install a new pan gasket (do not use sealant - it can clog the solenoids!).

2. Tighten the pan with a torque of 8–10 Nm (do not overtighten!).

3. Fill in fresh oil through a funnel up to the mark COLD on the dipstick.

4. Warm up the variator (drive 5–10 km) and check the level for hotness - it should be between HOT MIN And HOT MAX.

Step 5: Reset CVT adaptations

After changing the oil, the variator JF011E requires reset adaptations. This can be done in two ways:

  • 🔧 Through Consult III Plus (officials) - team Relearn CVT.
  • 🔧 Manually: Disconnect the battery terminal for 10 minutes, then follow the procedure:
    1. Start the engine, let it run for 1 minute P.
    2. Switch to D, hold the brake for 3 seconds.
    3. Convert to R, hold for 3 seconds.
    4. Repeat the cycle 5 times.
💡

Don't miss the adaptation reset! Without this, the variator will operate in “emergency” mode, which will lead to increased wear on the belt and pulleys.

Common mistakes when changing oil and their consequences

Even experienced craftsmen sometimes make mistakes that reduce the life of the variator. Murano Z51. Here TOP-5 fatal mistakes:

  • 🚫 Using the wrong oil (For example, DEXRON instead of NS-3). Consequences: belt slipping, overheating, failure after 10–20 thousand km.
  • 🚫 Incomplete replacement (only drain and fill without flushing). Old oil mixes with new oil and the additives become ineffective.
  • 🚫 Overfilling or underfilling oil. Overfilling leads to foaming and loss of pressure, while underfilling leads to oil starvation of the pulleys.
  • 🚫 Ignoring filter replacement. A clogged fine filter leads to a drop in pressure and wear on the pump.
  • 🚫 Using sealant instead of gasket. The sealant may peel off and clog the valve body solenoids.

Another common mistake is changing the oil "cold". In this case, only 20–30% of the volume is drained, and the bulk of the dirt remains inside. Always warm up the variator before draining!

What happens if you don't change the oil at all?

With a mileage of over 100 thousand km without changing the oil in the variator Murano Z51 a chain reaction begins:

1. The oil loses viscosity and stops dissipating heat → the pulleys overheat.

2. The belt slips, erasing the working surfaces of the pulleys → metal shavings appear.

3. Chips clog filters and solenoids → pressure in the system drops.

4. The variator goes into “emergency mode” with an error P17F0 (belt fault).

5. Repairs cost 150–250 thousand rubles. (replacement of pulleys, belt, valve body).

Replacement cost: service vs independently

Prices for changing oil in a variator Nissan Murano Z51 vary greatly depending on the region and type of service:

Replacement type Cost in service (₽) Cost yourself (₽)
Partial (4–5 l) 3 000–5 000 1 500–2 500
Full (9–10 l, without rinsing) 6 000–9 000 3 000–4 500
Full + washing + filters 10 000–15 000 5 000–7 000

Replacing it yourself is cheaper, but requires time and tools. If you have never worked with CVTs, it is better to turn to specialists - errors when servicing CVTs are very expensive.

Where to look for good service? Focus on:

  • 🔧 Reviews for Drive2 or Yandex.Maps (look for mentions specifically about Murano Z51).
  • 🔧 Availability of equipment for hardware replacement (For example, Launch CReader).
  • 🔧 Guarantee for work (good services provide 10-20 thousand km).

    • Frequently asked questions (FAQ)

    Is it possible to mix oil NS-2 And NS-3 in the variator Murano Z51?

    No! NS-2 And NS-3 They have different viscosities and additive packages. Mixing will cause the oil to foam and lose its properties. If you don’t know what’s in the variator, do it complete replacement with flushing.

    How to check the oil level in a variator Murano Z51?

    1. Warm up the variator (drive 10–15 km).

    2. Place the car on a level surface.

    3. With the engine running, switch the selector through all modes (P-R-N-D) with a delay of 3 seconds.

    4. Take out the dipstick, wipe it, insert it back and take it out again.

    5. The level should be between HOT MIN And HOT MAX.

    ⚠️ If the oil is higher HOT MAX - drain the excess through the stopper! Overfilling is just as harmful as underfilling.

    What should you do if, after changing the oil, the variator begins to twitch?

    Probable reasons:

    1. Adaptations have not been reset (follow the procedure described in Step 5).
    2. The wrong oil was used (e.g. NS-2 instead of NS-3).
    3. Air has entered the variator (you need to circulate the oil through the system, switching modes).
    4. Solenoids clogged (diagnostics required Consult III).

    If the jerking does not disappear after resetting the adaptations, contact the service to check the pressure in the valve body.

    How long does a variator last? Murano Z51 with proper maintenance?

    If you follow the oil change schedule (every 60 thousand km) and use the original NS-3 variator JF011E passes easily 250–300 thousand km without major repairs. Record cases - 400+ thousand km (with an oil change every 40 thousand km).

    The main enemies of the variator:

    • 🔥 Overheating (towing, traffic jams in the heat).
    • ❄️ Cold starts in winter (oil thickens, belt wears out).
    • 🚗 Aggressive driving (sharp acceleration when cold).
    Is it possible to drive with an error? P17F0 (variator belt malfunction)?

    ❌ Absolutely not! Error P17F0 means the CVT belt is slipping due to worn pulleys or low oil pressure. Further exploitation will lead to:

    • 🔥 Complete grinding of the working surfaces of the pulleys (repair ~200 thousand rubles).
    • 💥 The belt breaks (the variator will get stuck).

    When this error appears immediately turn off the engine and evacuate the car to a service center.
