Changing the oil in the <em>Nissan Murano Z52</em>variator: a complete guide with nuances

Nissan Murano Z52 with variator JF011E is a reliable crossover, but its continuously variable transmission requires special attention to maintenance. Unlike classic automatic transmissions, a variator is extremely sensitive to the quality and condition of the oil: ignoring replacement leads to belt slipping, overheating and expensive repairs. Owners often ask questions: what kind of oil to fill, how often to change it, and is it possible to do without visiting a service center?

This article contains detailed instructions for changing the oil in a variator Murano Z52 (2015–2026), based on manuals Nissan, experience of car mechanics and reviews from owners. We will analyze official recommendations, alternative approaches (partial vs complete replacement), a list of tools and typical mistakes that reduce the life of the variator. Let’s also answer a controversial question: is it worth flushing the gearbox when changing the oil?

Official recommendations Nissan for changing the oil in the variator Murano Z52

Manufacturer in service booklets for Murano Z52 indicates that there is oil in the variator does not require replacement throughout the entire service life of the vehicle - subject to “normal” operating conditions. However, this statement is only true for Europe and the USA, where cars are rarely used in difficult conditions. For Russia, with its frosts, traffic jams and dusty roads, Nissan corrects recommendations:

• 📅 Replacement frequency: every 60,000 km or once every 4 years (whichever comes first). For regions with extreme climates (below –30°C in winter or above +35°C in summer), the interval is reduced to 40,000 km.
• 🛢️ Oil type: only original Nissan CVT Fluid NS-3 (art. KLE52-00004). Fill in analogues (for example, Idemitsu CVTF or Mobil CVT) is possible, but at the risk of losing the warranty.
• ⚠️ Oil volume: with a partial replacement, ~5 liters will be required, with a complete replacement (with removing the pan and replacing the filter) - up to 12 l.

Important: Nissan does not provide for replacing the variator oil filter as a separate procedure. The filter is changed only when complete oil change (with removal of the pallet), and its article number - 31726-31X0A. Attempts to “save money” and leave the old filter lead to clogging of the valve body channels and accelerated belt wear.

⚠️ Attention: If the variator is already experiencing jerking, delays when switching, or a humming noise, changing the oil may temporarily improve the situation, but will not solve the problem. In such cases, diagnostics on a scanner is required (for example, Consult-III Plus) to check the pressure in the lines and the condition of the belt.

Partial vs full oil change: what to choose for Murano Z52?

Methods for changing oil in a variator vary in complexity, cost and efficiency. Let's look at both options with their pros and cons.

Parameter	Partial replacement	Complete replacement
Oil volume	4–5 l	10–12 l
Cost (with labor)	3 000–5 000 ₽	8 000–12 000 ₽
Lead time	30–40 minutes	2–3 hours
Efficiency	~40% oil change	~90% oil change
Replacing the filter	❌ No	✅ Yes

Partial replacement Suitable for prevention if the oil has not yet had time to degrade significantly (light brown color, no burnt smell). The procedure is simple: drain the old oil through the plug and fill in new oil to the level. However, this method does not remove deposits from the bottom of the pan and does not clean the magnets of metal shavings.

Complete replacement requires special equipment (for example, an apparatus for pumping oil under pressure) or multiple draining/filling with running the box between cycles. This method is preferable if:

• 🔄 The oil has not been changed for more than 80,000 km.
• 🚨 There are signs of variator wear (jerking, vibrations).
• 🔧 It is planned to replace the filter or pan seal.

Tools and materials for changing the oil in the variator Murano Z52

To change the oil yourself, you will need a specialized tool. Some items (for example, a drain plug wrench) can be replaced with analogues, but the risk of stripping the threads or damaging the pan increases.

• 🔧 Tools:
• 🔩 10 mm square key for drain plug (original art. 38166-4M000).
• 🔧 10 mm socket for pallet bolts.
• 🛠️ Torque wrench (plug tightening torque - 35 Nm, pallet - 10 Nm).
• 🧲 Powerful magnet for collecting metal shavings from a pallet.
• 🔧 Flat screwdriver for removing old sealant.
• 🛢️ Materials:
• 🛢️ Oil Nissan CVT Fluid NS-3 — 12 liters for a complete replacement.
• 🧴Sealant Loctite 574 or ThreeBond 1217 for a pallet.
• 🔧 Variator filter (art. 31726-31X0A).
• 🧻 Lint-free rags, gloves, drainage container (minimum 6 l).

Note: if you plan to flush the variator, additional flushing fluid (For example, Liqui Moly CVT Spulung) and a pumping apparatus. Flushing is recommended only if the oil is heavily contaminated or after purchasing a used car with an unknown service history.

Step-by-step instructions for changing the oil in the variator Murano Z52

Let's look at the oil change process using an example. complete replacement with removing the pan and replacing the filter. For partial replacement, simply follow steps 1–5 and 12–14.

1. Drain old oil. Warm up the variator (oil temperature should be ~50°C). Place a container under the drain plug and unscrew it with a square wrench. Wait until it drains completely (about 5 l). Do not touch the pallet - he's hot!

2. Removing the pallet. Unscrew the 18 bolts of the pan (starting from the corners) and carefully remove it. Be careful - ~1 liter of oil remains in the pan. Clean the magnets from shavings and rinse the tray with kerosene.

3. Replacing the filter. The variator filter is secured with 3 bolts. Remove it, install a new one (art. 31726-31X0A). Check the condition of the O-ring on the filter; replace if damaged.

4. Cleaning the hydraulic unit. Remove the hydraulic unit (6 bolts), wash its channels with compressed air. Ignoring this step is the main reason for premature wear of the variator after an oil change! Reinstall the valve body, replacing the gasket (art. 31397-31X0B).

5. Pallet installation. Apply sealant to the edge of the pan (a thin layer), install it in place and tighten the bolts evenly in a crisscross pattern. 10 Nm.

6. Refill with new oil. Fill in ~5 liters of new oil through the filler neck (under the hood, next to the battery). Start the engine, warm up the box and check the level on the dipstick (should be between the marks HOT).

For a complete replacement, repeat the drain/fill procedure 2–3 times at intervals of 10–15 km. This will force the old oil out of the torque converter.

Typical mistakes when changing oil and their consequences

Even experienced car owners make mistakes that reduce the life of the variator. Here are the most common:

• ❌ Using non-original oil. Analogs (for example, Ravenol CVT) may not meet viscosity requirements Nissan, which leads to belt slippage and overheating. Consequence: replacing the variator after 20,000–30,000 km.
• ❌ Overfilling or underfilling oil. Excess oil leads to foaming and loss of pressure, too little leads to oil starvation. The optimal level is between the marks HOT on the dipstick when the box is warm.
• ❌ Ignoring filter replacement. The old filter becomes clogged with wear products, which reduces the pressure in the system. Symptoms: delays when switching, jerking.
• ❌ Tightening the pan bolts tightly. At a moment more 12 Nm the pan becomes deformed, which leads to oil leakage. Use a torque wrench!

⚠️ Attention: If after changing the oil the light on the dashboard comes on AT (transmission), stop immediately and check the oil level. Driving with the light on can damage the variator belt.

How to check the condition of the oil in the variator Murano Z52?

Oil diagnostics will help determine whether it requires replacement or whether the variator repair is already necessary. Carry out the check on a warm box (after 10–15 km of driving).

1. Color and smell. Fresh oil is transparent, light brown. If oil:

   • 🟤 Dark brown with a burnt smell → urgent replacement required.
   • ⚫ Black with metal particles → worn belt or bearings.
   • 🟡 Cloudy with foam → water ingress or oil overflow.

Testing with magnets. Remove the tray and inspect the magnets. The norm is fine metal dust. Large chips or melted particles indicate critical wear.

Viscosity test. Drop some oil onto the paper. If it is quickly absorbed and does not leave a greasy residue, the oil has lost its properties.

For an accurate diagnosis, send an oil sample for analysis to a laboratory (for example, Oil Club). The cost of the analysis is ~1,500 ₽, but it will show the metal content, the presence of antifreeze and the real life of the oil.

What to do if the oil in the variator turns black?

If the oil has turned black and smells like burning, a partial replacement will not help - a complete flushing of the variator is required, replacing the filter and valve body. In 70% of cases, this situation is accompanied by belt wear, and it is impossible to do without disassembling the box. The average cost of repairs is from 50,000 ₽ (belt and oil replacement) to 150,000 ₽ (major repairs).

FAQ: Frequently asked questions about changing the oil in the variator Nissan Murano Z52

Is it possible to use NS-2 oil instead of NS-3?

No. Oil NS-2 has a different viscosity characteristic and is not compatible with CVTs Murano Z52 (2015+ onwards). Using it will cause the belt to slip and overheat. NS-3 - the only oil approved by the manufacturer.

How much oil to fill during a partial change?

During a partial replacement, ~4.5 liters of oil are drained. You need to fill in exactly the same amount as drained. After replacement, check the level using the dipstick on a heated box.

Do I need to reset the oil aging counter after changing it?

Yes, if your Murano Z52 equipped with a system CVT Fluid Deterioration Data. Resetting is performed via a diagnostic scanner (for example, Launch X431) in the menu Transmission → CVT Fluid Reset.

Is it possible to drive with a slightly lower oil level?

For a short time (up to 500 km) - yes, but the risk of oil starvation increases. Prolonged driving at a low level leads to wear on the bearings and belt. Add oil of the same brand as in the box.

Which is better: an official service or an independent service station?

Official service guarantees original spare parts and oil, but the price is 30–50% higher. Independent service stations often skimp on filters or sealants. The best option is a service specializing in Nissan with a guarantee on work.
