Changing the oil in the Nissan Murano CVT: a complete guide with nuances for the Z51 and Z52

CVT Nissan Murano - 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 (CVT) does not require an oil change or that it is enough to “add according to the level”. It's a myth: CVT Murano (especially models Z51 2009–2014 and Z52 2015–2021) reacts critically to the aging of the transmission fluid. According to service center statistics, 80% of breakdowns of Murano CVTs after 150 thousand km are associated with untimely oil changes or the use of low-quality analogues.

This article contains an analysis of all the nuances: from choosing the original liquid NS-3 to step-by-step instructions with photos and videos. We'll also tell you why partial oil change in the variator Murano - this is a half-measure, and when a complete hardware flush is really required. If you plan to carry out the procedure yourself, pay attention to the block with common mistakes - they can cost you 200+ thousand rubles in repairs.

Frequency of oil changes in the Murano variator: official and real terms

Manufacturer in the manual for Nissan Murano Z51/Z52 indicates the oil change interval in the variator - every 90 thousand km or once every 6 years (whichever comes first). However, these figures are relevant for “ideal” operating conditions:

• 🌡️ Ambient temperature is not lower than -20°C and not higher than +35°C.
• 🛣️ Smooth driving style without sudden starts and braking.
• 🚗 No towing trailers or heavy loads.
• 💧 Using only original oil Nissan CVT Fluid NS-3.

In Russian realities (city traffic jams, frost, bad roads) the actual interval is reduced to 60–70 thousand km. Signs that it's time to change the oil immediately:

• 🔧 Jerks or delays when switching “virtual” gears.
• 🔊 A hum or whistle from under the hood when driving at low speeds.
• 📉 Decrease in acceleration dynamics (the variator becomes “stupid” when accelerating).
• 🚨 An error light appears on the dashboard P17F0 or P17F1 (overheating or oil wear).

⚠️ Attention: If you bought Murano with mileage and do not know the service history of the variator, Carry out the first oil change no later than 30 thousand km after the purchase. Old fluid may contain metal shavings, which will accelerate wear on the belt and cones.

What kind of oil to fill in the Nissan Murano variator: original vs analogues

For CVTs Murano Z51 (2009–2014) and Z52 (2015–2021) the only officially approved option — Nissan CVT Fluid NS-3 (article KLE52-00004 for a 4-liter canister). This oil was developed specifically for CVTs Jatco JF011E, which are installed on Murano. Its key features:

• 🔬 Improved anti-wear additives to protect the belt and cones.
• 🌡️ Stable viscosity at extreme temperatures (from -40°C to +150°C).
• 🛡️ Protection against oxidation and sludge formation.

Cost of the original NS-3 - about 6,000–7,000 rubles. for 4 liters. Many car owners are looking for analogues, but it is important to understand the risks here:

Analogue	Compatibility	Price (4 l)	Risks
Idemitsu CVTF	Partial	4,500–5,000 rub.	May foam under high loads
Ravenol CVT Fluid	High	5,500–6,000 rub.	Not suitable for CVTs with mileage >150 thousand km
Mobil CVT Fluid	Low	3,800–4,200 rub.	Accelerates belt wear in frosts below -25°C

⚠️ Attention: If you decide to use analog, do a test before replacing completely: fill in 1 liter of new oil and drive 500 km. If jerking or noise occurs, drain it immediately and return to NS-3.

For used CVTs more than 100 thousand km some masters recommend Nissan CVT Fluid NS-2 (article KLE50-00004). It is thicker and better protects worn parts, but not suitable for new CVTs - may cause the belt to slip.

Preparing for replacement: tools and consumables

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

New oil (8-10 liters for a complete change)|CVT filter (part number 31726-1XF0A)|Pan gasket (part number 31397-1XF0A)|10 and 14 mm wrench (for drain plug)|24 mm socket (for fill plug)|Funnel with long spout|Drain container (minimum 6 liters)|Torque wrench (for tightening plugs)|Carburetor cleaner (for flushing pan)-->

Also prepare:

• 🧤 Gloves and rags (oil has an aggressive effect on the skin).
• 🔧 Jack or lift (working on the ground is inconvenient).
• 📱 Phone for filming the process (useful if something goes wrong).

If you plan complete oil change (and not partial), you will additionally need:

• 🔄 A device for washing the variator (can be rented at a car service).
• 🧴 12–14 liters of oil (to completely displace the old liquid).

⚠️ Attention: Do not use sealant to seal the pan! Original gasket 31397-1XF0A has a rubber seal and does not require additional processing. The sealant may clog the oil passages.

How to check the oil level in a Murano CVT?

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

2. Place the car on a level surface.

3. Switch the variator selector through all positions (P-R-N-D), holding each position for 5 seconds.

4. Return the selector to position P and check the level through the dipstick (it is located to the right of the engine, under the hood).

5. The level should be between the "MIN" and "MAX" marks. If the oil is above “MAX”, drain the excess through the drain plug.

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

The process of changing the oil in the variator Nissan Murano consists of several stages. We will describe partial replacement (drain-fill), which you can do yourself. For a complete replacement, it is better to contact a service center - they use a high-pressure apparatus that displaces up to 95% of the old oil.

Step 1: Drain the old oil

1. Start the engine and warm up the variator to 50–60°C (you can drive 5–10 km).

2. Lift the car on a lift or drive it into a pit.

3. Remove the crankcase protection (if equipped).

4. Place a container for draining and unscrew the drain plug with a 14 mm wrench. Be careful - the oil will be hot!

5. Wait until the maximum amount of liquid has drained (usually 4–5 liters).

Step 2: Replace the filter and wash the pan

1. Unscrew the 18 bolts of the variator pan (10 mm wrench) and carefully remove it. There will still be ~1 liter of oil left inside - drain carefully.

2. Remove the old filter (it is secured with 3 bolts) and install the new one.

3. Clean the tray and magnets from metal shavings. Use carburetor cleaner and lint-free rags.

4. Install a new gasket and tighten the pan bolts crosswise with a force of 8–10 Nm.

Step 3: Add new oil

1. Screw in the drain plug with a new washer (tightening torque: 35 Nm).

2. Fill in new oil through the filler hole (24 mm plug) using a funnel. A partial replacement will require ~5 liters.

3. Start the engine and let it idle for 2-3 minutes.

4. Check the oil level with a dipstick and add if necessary.

After replacement, drive 10–15 km and recheck the level. If the oil turns black or has a burning smell, this is a sign severe wear of the variator, and diagnostics may be required.

Common mistakes when changing oil and their consequences

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

• 🔧 Retightening the drain or filler plug. Leads to thread failure on the variator housing. Repairs will cost 15–20 thousand rubles. (replacement of crankcase + work).
• 🧴 Mixing different types of oils. For example, NS-2 And NS-3. This causes a chemical reaction that causes the fluid to lose its properties and form sludge.
• 🧲 Ignores metal shavings on magnets. If there are a lot of chips (more than 1 mm layer), this is a sign critical wear of cones. In this case, changing the oil will not help - the variator needs to be repaired.
• 🌡️ Changing the oil on a cold variator. Cold fluid is more viscous and you are only draining 30-40% of the total volume. The remainder of the old oil will mix with the new one and worsen its properties.

Another common mistake is use of non-original filters. Cheap analogues (for example, from SCT or JapanParts) may have a low-quality paper element that falls apart after 10–20 thousand km and clogs the oil channels. Original filter 31726-1XF0A costs about 1,500 rubles, but its service life is 60–90 thousand km.

⚠️ Attention: If after changing the oil the variator begins to “kick” or noise appears, stop driving immediately! This could be a sign airing the system (if you haven’t added oil) or torque converter locking (if overfilled). In both cases, diagnosis is required.

The cost of changing the oil in a Murano variator: service vs independently

Prices for changing oil in a variator Nissan Murano depend on the type of procedure and region. Below is a comparative table for Moscow and the regions (as of June 2026):

Replacement type	Moscow (RUB)	Regions (RUB)	What's included
Partial replacement (drain-fill)	3 500–5 000	2 500–3 500	Work + 5 l of oil (without filter)
Complete replacement (hardware)	8 000–12 000	6 000–9 000	Work + 12 liters of oil + filter
Self-replacement	5 000–7 000	5 000–7 000	Oil (8 l) + filter + gasket

The savings on self-replacement are obvious, but it is important to consider hidden risks:

• 🔧 Without experience, it is easy to damage the pallet gasket or break the plug thread.
• 🧪 Without special equipment, it is impossible to control the quality of washing.
• 📝 The service provides a guarantee for work (usually 1-2 months), if you replace it yourself, all the risks are on you.

If you decide to contact the service, choose specialized CVT repair centers. Regular service stations often do not have experience working with Jatco JF011E and may make mistakes. A good sign is availability in the service diagnostic scanner Consult III Plus, which allows you to reset the oil aging counter in the CVT ECU.

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

CVT Nissan Murano - this is high precision mechanism, where the slightest deviation in the operation of the fluid leads to a chain reaction of breakdowns. This is what happens when overdue oil change:

1. 100–120 thousand km: The oil loses its cleaning properties and sludge begins to form. The first jerks appear during acceleration.
2. 130–150 thousand km: The friction between the belt and the cones increases. The variator starts to “slip” when it’s hot (for example, when overtaking).
3. 160–180 thousand km: The belt slips, causing overheating and deformation of cones. Lights up on the dashboard Check Engine with errors P17F0 or P0841.
4. 200+ thousand km: The belt and cones are completely worn out. The variator stops transmitting torque - required major renovation (from 150 thousand rubles) or replacement with a contract one (from 200 thousand rubles).

It is especially dangerous to ignore oil changes in CVTs Murano Z51 (pre-restyling models). Their variators are more sensitive to fluid quality due to the design features of the torque converter. For example, when contaminated oil valve lock-up may jam, which will lead to blocking the box at speed.

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

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

NS-2 suitable only for CVTs Murano with mileage more than 150 thousand km, where increased wear of the cones is observed. For new boxes (up to 100 thousand km) NS-2 too thick and may cause belt slippage. It should also not be mixed with NS-3 - only complete replacement!

How much oil is needed for a complete change?

For complete hardware replacement 12–14 liters of oil will be required (depending on the degree of contamination). With a partial replacement (drain-fill), 5–6 liters are required, but this only renews 40–50% of the liquid. For maximum effect, it is recommended to repeat the partial replacement 2-3 times at intervals of 500-1000 km.

How to check that counterfeit oil is poured into the variator?

Signs of a fake NS-3:

• 📦 Canister without a holographic sticker or with a blurry font.
• 🧪 The oil has a sharp chemical smell (the original smells neutral).
• 🌡️ When heated to 80°C, the fake becomes cloudy or delaminates.

If you suspect that you have uploaded counterfeit goods, drain it immediately - fake oil can destroy the variator in 5-10 thousand km.

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

Yes, in CVTs Murano from 2015 (models Z52) The ECU monitors the “aging” of the oil based on mileage and load. After replacement, the counter must be reset via a diagnostic scanner (for example, Consult III Plus or Launch X431). Without a reset, the ECU may lock up the torque converter prematurely, resulting in jerking.

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

Short-term (up to 500 km) - yes, but below the "MIN" mark on the dipstick The level should not drop. Long-term driving with a reduced level leads to:

• 🔥 Overheating of the variator (oil not only lubricates, but also cools).
• 🛠️ Accelerated wear of bearings and belt.
• 🚨 Errors appearing P0776 (oil pressure) or P0841 (control circuit malfunction).

If the level falls below "MIN", don't start the car - add oil to normal level.
