How to properly change the oil in a Nissan Murano Z50 CVT: a complete guide

CVT Nissan Murano Z50 - This is a complex unit that requires special attention to maintenance. Many owners mistakenly believe that continuously variable transmission (CVT) does not need regular oil changes, but this is a myth. Neglecting this procedure leads to overheating, wear of the belt and cones, and in the worst case - to complete failure of the variator.

In this article we will look at which oil is suitable for the Murano Z50 CVT, how often to change it, and we will provide step-by-step instructions taking into account the nuances of this particular model. You will also learn what mistakes car owners most often make and how to avoid them. If you plan to carry out the replacement yourself, here you will find all the necessary parts, from tools to the draining and filling algorithm.

Why changing the oil in the Murano Z50 CVT is critical

CVT Jatco JF011E, installed on Murano Z50, operates under conditions of high loads and temperatures. The oil in it performs several functions at once:

• 🔥 Heat dissipation — prevents overheating of the belt and pulleys.
• ⚙️ Lubrication of rubbing parts — reduces wear of cones and bearings.
• 🧲 Torque transmission — provides a smooth change in gear ratio.
• 🧹 Cleaning metal shavings — keeps wear products in suspension.

Over time, the oil loses its properties: oxidizes, becomes saturated with abrasive particles and ceases to lubricate effectively. This leads to:

• 🚨 Jerking during acceleration - due to belt slippage.
• 🔊 Humming or whistling - signal about insufficient lubrication of bearings.
• ⚠️ Emergency mode - when the ECU detects a critical state of the variator.

⚠️ Attention: If you ignore the oil change, the CVT Murano Z50 may fail after 120–150 thousand km. Repairs will cost 150–300 thousand rubles - this is 30–50% of the cost of a used crossover.

The manufacturer states that the oil in the variator JF011E filled for the entire service life, but this is only true for “ideal” operating conditions (European roads, moderate climate, gentle driving style). In reality replacement is required every 60–90 thousand km - especially for Russian conditions with sudden temperature changes and poor quality roads.

What kind of oil to pour into the Nissan Murano Z50 variator

For CVT JF011E fits only original oil Nissan CVT Fluid NS-3 (art. KE909-99932). This is a synthetic fluid designed specifically for continuously variable transmissions. Nissan And Renault taking into account their design features. Using other oils (even universal ATF) will lead to:

• 🛑 Loss of smooth shifting - due to unsuitable viscosity.
• 🔥 Overheating - if the oil cannot withstand high temperatures.
• ⚠️ Valve block failure - due to incompatibility with seal materials.

Alternative options (only if the original is not available!):

Manufacturer	Oil name	Article	Notes
Idemitsu	CVT Type NS-3	30450027-004	Complete analogue of the original, approved Nissan
Ravenol	CVT NS-3 Fluid	4014835755406	High temperature stability
Motul	Multi CVT Fluid	105777	Suitable for partial replacement

Oil volume to change:

• 🔄 Partial replacement (drain through the plug): 4–5 liters.
• 🔄 Complete replacement (with flushing): 10–12 liters.

⚠️ Attention: Never mix NS-2 And NS-3! These oils have different chemical compositions. If the variator was flooded NS-2, before moving to NS-3 required complete flushing of the system.

Tools and materials for oil change

To change the oil in the variator yourself Murano Z50 you will need:

New oil Nissan CVT Fluid NS-3 (minimum 6 liters)|New variator oil filter (art. 31726-3XF0A)|O-ring for drain plug (art. 31397-3XF0A)|Set of sockets and 10 mm wrench|Funnel with extension for filling|Container for draining waste (minimum 6 liters)|Gloves and rags|Torque wrench (for tightening the plug with a torque of 35 Nm)-->

Additionally you may need:

• 🔧 Filter puller — if you plan to change the coarse filter.
• 🧴 Carburetor Cleaner - for washing the pan.
• 📊 OBD-II scanner — to reset the variator adaptations after replacement.

If this is your first time replacing, we also recommend purchasing variator pan gasket (art. 31397-3XF0B). It is disposable and often breaks when removing the pallet. Cost of laying - approx. 1,500 rubles, but it will eliminate oil leaks after assembly.

Where to buy spare parts? It is better to order the original filter and gasket from official dealers Nissan or in trusted online stores (for example, Exist.ru, Autodoc). Avoid shopping at markets - there is a high risk of running into a fake.

Step-by-step instructions for changing the oil in the Murano Z50 variator

The oil change procedure consists of several stages. We will consider partial replacement (without removing the pan) and complete replacement (with washing and replacing the filter).

1. Partial replacement (draining through the plug)

This method allows you to update 40–50% oil and is suitable for routine maintenance.

1. Warm up the variator to operating temperature (drive 10–15 km). This is necessary so that the oil becomes less viscous and drains better.

2. Place the car on a level surface and secure it with the handbrake. Raise the front end on a jack or use an inspection pit.

3. Remove the crankcase protection (if equipped) and find variator drain plug — it is located on the pallet on the right (in the direction of travel).

4. Place the drain container, unscrew the plug with a 10 mm wrench and wait until the oil drains (about 4–5 liters).

5. Tighten the plug with a new sealing ring (tightening torque - 35 Nm).

6. Fill in new oil through filler hole (located on top, under the hood). Use a funnel with an extension.

7. Check the oil level on the dipstick (should be between the marks MIN And MAX when the variator is warmed up).

2. Complete replacement (including washing and replacing the filter)

This method takes more time but allows you to update 90–95% oil and remove wear products.

1. Drain the oil through the plug (as in a partial replacement).

2. Remove the variator pan by unscrewing all the bolts around the perimeter. Be careful - about 1 liter of oil will remain in the pan!

3. Clean the tray and magnets from metal shavings. For severe contamination, use carburetor cleaner.

4. Replace coarse filter (located inside the variator, secured with 3 bolts).

5. Install a new pan gasket and reassemble everything in reverse order.

6. Fill with new oil, then bleed the system:

   • 🔄 Start the engine and let it idle for 2-3 minutes.
   • 🔄 Alternately switch the variator selector to all positions (P → R → N → D), holding each for 5 seconds.
   • 🔄 Repeat the procedure 2-3 times, then check the oil level.

⚠️ Attention: After a complete oil change, the variator may work a little differently (for example, react more sharply to the gas pedal). This is normal - the ECU adapts to the new fluid within 100–200 km mileage

Typical mistakes when changing the oil in the Murano Z50 variator

Even experienced car owners make mistakes that can lead to CVT breakdown. Here are the most common:

• 🚫 Using the wrong oil - for example, ATF instead of CVT Fluid NS-3. This leads to belt slippage and accelerated wear.
• 🚫 Underfilling or overfilling of oil:
  • 🔽 Underfilling → overheating and oil starvation.
  • 🔼 Overflow → foam in oil and loss of lubricating properties.
• 🚫 Ignoring filter replacement - the old filter does not retain metal shavings that circulate through the system.
• 🚫 Tightening the drain plug without a torque wrench - overtightening leads to thread breakage, weak tightening leads to leaks.
• 🚫 Lack of variator adaptation — after changing the oil, the ECU needs to be “trained” to the new characteristics of the fluid.

Critical error: flushing the variator with solvents (for example, diesel fuel or kerosene). This destroys seals and seals, leading to leaks and air entering the system. For rinsing, use only special fluids for CVT (For example, Wynns CVT Cleaner).

Another common problem is incorrect oil level check. The level needs to be controlled:

• 🔹 On warmed up variator (oil temperature 50–80°C).
• 🔹 When running engine (selector in position P).
• 🔹 On flat surface (the slope distorts the dipstick readings).

What to do if the variator does not shift after changing the oil?

If after changing the oil the seriator Murano Z50 stopped shifting gears or caught fire CHECK ENGINE, the reasons may be as follows:

1. **Incorrect oil level** - drain the excess or add to the correct level.

2. **Air getting into the system** - bleeding is required (several cycles of selector switching with the engine running).

3. **Poor quality oil or filter** - replace with original parts.

4. **Adaptation failure** - reset errors via OBD-II scanner (eg Launch X431).

If the problem persists, contact the service to diagnose the valve body and solenoids.

When an unscheduled oil change is required

In addition to the scheduled intervals (60–90 thousand km), the oil in the variator Murano Z50 must be changed ahead of schedule in the following cases:

• 🚗 Buying a used car — if there is no service history, it is better to change the oil immediately.
• 🌡️ Operation in harsh conditions:
  • 🔥 Frequent driving in traffic jams (variator overheating).
  • 🏔️ Towing a trailer or another vehicle.
  • ❄️ Extremely low or high temperatures (below -30°C, above +35°C).
• ⚠️ Symptoms of a variator malfunction appear:
  • 🔊 Hum or whistle when moving.
  • 🛑 Jerks when accelerating or braking.
  • 💡 Burning lamp AT TEMP on the dashboard.
• 💧 Oil leak - if red spots appear under the car, immediately check the level and eliminate the cause of the leak.

If the oil in the variator has darkened, it has burnt smell or visible in it metal particles - this is a signal of critical wear of parts. In this case, a regular oil change is not enough: you will need CVT diagnostics and possibly renovations.

How to check the condition of the oil? Take out the variator dipstick and drop oil onto a white paper napkin:

• 🟢 Light yellow color — the oil is in good condition.
• 🟠 Brown shade - replacement required.
• 🔴 Dark brown or black color — the oil is heavily contaminated and needs to be flushed.
• ⚫ Presence of metal shavings - critical wear, repair required.

The cost of changing the oil in the Murano Z50 variator

The price of an oil change depends on the method (partial or full) and region. Below is an indicative price list for Moscow and the regions:

Service	Moscow (RUB)	Regions (RUB)	On your own (RUB)
Partial replacement (4–5 l)	3 000–5 000	2 000–3 500	1 500–2 500*
Full replacement (10–12 l)	8 000–12 000	5 000–8 000	4 000–6 000*
Replacing the variator filter	1 500–2 500	1 000–2 000	500–1 000**
Flushing the variator	3 000–5 000	2 000–3 500	2 000–3 000***

* Cost of spare parts only (oil + filter).

** Price of the original filter.

*** Cost of flushing fluid (for example, Wynns CVT Cleaner).

You can save money if you carry out the replacement yourself. However complete replacement with flushing requires experience - it is better to entrust it to professionals. The service uses special equipment (for example, CVT flush machine), which displaces old oil under pressure, removing up to 98% completion.

If you decide to contact the service, choose proven stations with good reviews. Be sure to check:

• 🔹 What kind of oil will be poured (should be NS-3).
• 🔹 Do they change the filter (this is mandatory in a complete replacement!).
• 🔹 Do they provide a guarantee for the work (at least 6 months).

FAQ: Frequently asked questions about changing the oil in the Murano Z50 variator

Can NS-2 oil be used instead of NS-3?

No, these are liquids of different composition. NS-3 has improved anti-friction and heat-resistant properties. If the variator had NS-2, before moving to NS-3 required full flush.

How much oil to fill during a partial change?

When draining, approximately 4–4.5 liters. Fill in the same amount of new oil, then check the level on the dipstick and add if necessary.

Do I need to reset the CVT adaptations after changing the oil?

Yes, especially if the oil is heavily contaminated or has not been completely replaced. Adaptations are reset via a diagnostic scanner (for example, Launch X431 or Delphi). Without this, the ECU may not control the variator correctly, which will lead to jerking.

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

The consequences depend on the mileage:

• 100–150 thousand km - jerking, increased noise, deterioration in dynamics.
• 150–200 thousand km — belt slipping, overheating, failure of solenoids.
• 200+ thousand km — destruction of cones and belt, complete failure of the variator.

CVT repair will cost 150–300 thousand rubles - It’s cheaper to change the oil regularly.

Is it possible to mix oil from different manufacturers?

Not recommended. Even if both oils meet specification NS-3, their additives may conflict. If you had to add oil from another brand, do this as soon as possible. complete replacement.
