CVT oil for Nissan Murano Z51: how to choose and replace without errors

CVT Nissan Murano Z51 (2015–2023) is one of the most reliable in the Japanese brand’s lineup, but only with proper maintenance. The main enemy of a continuously variable transmission is overheating and oil contamination, which lead to belt slipping, jerking and costly repairs. Owners often ask questions: what liquid to fill, how often to change it and is it possible to save money on analogues?

This article contains only verified data: from official recommendations Nissan to the experience of service centers. We'll sort it out unique features of the JF017E variator (installed on Murano Z51 with engines VQ35DD And VQ25HR), compare the original oil NS-3 with analogues, and we will show how to avoid typical mistakes when replacing. Without water - just facts, tables and step-by-step instructions.

Official Nissan requirements: what oil to fill in the Murano Z51 variator

The manufacturer clearly regulates the type of oil for the variator JF017E in Murano Z51: this Nissan CVT Fluid NS-3 (article KLE52-00004). The fluid is designed specifically for the latest generation continuously variable transmissions with enhanced anti-friction additives. Why exactly NS-3, not outdated NS-2?

The point is in the design of the variator: in Murano Z51 a belt with increased load and modified cones are used. NS-3 has on 30% higher thermal-oxidative stability compared to NS-2, which is critical for a heavy crossover with a motor VQ35DD (260 hp). Using a different fluid will void the warranty and shorten transmission life.

• 🔹 Original article: KLE52-00004 (4 l) or KLE52-00001 (1 l)
• 🔹 Tolerance: only NS-3 (not compatible with NS-2 or NS-1!)
• 🔹 Viscosity: optimized for operation at temperatures from -40°C to +150°C
• 🔹 Service life: officially - “for the entire service life”, but the real replacement interval is 60–90 thousand km

Important: Nissan has not certified any alternative fluid for Murano Z51. However, some analogues (for example, Idemitsu CVTF or Ravenol CVT NS-3) have been independently tested and show comparable results. More on this in the next section.

Analogues of NS-3: is it possible to save money without risking the variator

Original oil NS-3 is expensive (from 6,000 rubles for 4 liters), so many owners are looking for analogues. It's not worth the risk: incompatible liquid leads to belt slippage, increased pressure in the valve body and breakdown of solenoids. However there is 3 proven analogueswhich service centers use:

Brand	Article	NS-3 compatible	Price for 4 l (rub.)
Idemitsu	30050075-004	Full (approved for Nissan in Asia)	4 800–5 200
Ravenol	4014835734940	Partial (tests show stability up to 80 thousand km)	5 500–6 000
Mitsubishi DiaQueen CVTF-J4	MZ320266	Conditional (only for emergency topping up!)	4 500–4 900

⚠️ Attention: even approved analogues can cause switching delays at cold start. If after replacement there are jerks - flush the system immediately and upload the original. In 2022 Nissan Russia issued a bulletin about increased wear of CVTs when used Ravenol in regions with frosts below -30°C.

Advice: if you decide to take a chance with an analogue, buy 1 liter of original NS-3 for topping up. When mixing (up to 20% of the volume), there will be no negative consequences, but it is better to avoid such situations.

Replacement frequency: when to change the oil in the Murano Z51 variator

Official regulations Nissan reads: oil in variator Murano Z51 does not require replacement. This is a marketing ploy: in practice, the liquid degrades after 60 thousand km. Signs of "tired" oil:

• 🚨 Jerks when accelerating (especially at speeds of 40–60 km/h)
• 🚨 Rumble from under the hood when cold
• 🚨 Slow response on the gas pedal
• 🚨 Darkening of the oil (checked with a probe)

Recommended replacement intervals:

• 🔧 60 thousand km — partial replacement (3–4 l)
• 🔧 90 thousand km — complete replacement (8–9 l) with flushing
• 🔧 120 thousand km — replacement + diagnostics of solenoids

⚠️ Attention: If you frequently tow a trailer or drive off-road, reduce the interval to 40–50 thousand km. CVT Murano Z51 does not have an additional cooling radiator, and the oil overheats faster than in X-Trail or Qashqai.

What happens if you don't change the oil?

When driving over 100 thousand km without changing the fluid, metal shavings form in the variator, which clog the filter and oil pump. This leads to oil starvation, belt slippage and destruction of cones. The average cost of repairs is from RUB 250,000.

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

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

• 🔧 8–9 liters oils NS-3 (for complete replacement)
• 🔧 Variator filter (article 31726-3XF0A)
• 🔧 Pan gasket (31397-3XF0A)
• 🔧 Key for 10 And head 14 for drain plug
• 🔧 Funnel with long spout (for filling through the dipstick)

Replacement process:

1. Warm up CVT up to 60–70°C (drive 10–15 km).
2. Drain the old oil through a plug (volume ~4 l).
3. Remove the pan, clean the magnets from shavings.
4. Replace the filter (in Murano Z51 it is disposable!).
5. Fill with new oil through the dipstick (you will need a funnel).
6. Bleed the system: start the engine, switch the selector to all modes with a delay of 5 seconds.
7. Check the level on a warm variator (should be between HOT MIN And HOT MAX).

⚠️ Attention: if after changing the oil quickly darkens (within 1–2 thousand km), this is a sign friction wear. In this case, diagnostics of the valve body is required and the belt can be replaced.

Common mistakes when changing oil and how to avoid them

Even experienced technicians make mistakes when servicing the variator Murano Z51. Here TOP-5 critical misses and their consequences:

Error	Consequences	How to avoid
Underfilling/overfilling of oil	Foaming → oil starvation → belt wear	Check the level strictly on a warm variator
Using a non-original filter	Filter element rupture → chips entering the hydraulic unit	Buy only 31726-3XF0A (original or Mahle)
Mixing NS-3 with NS-2	Chemical reaction → sediment formation → solenoids jamming	Never mix different types of oils!
Replacement without flushing the pan	Remaining chips and dirt reduce the life of the new oil.	Clean the magnets and tray thoroughly with solvent.
Ignoring error P17F0	Overheating of the variator → belt deformation	Reset the error with the scanner after changing the oil

Pay special attention pallet gasket. B Murano Z51 it is disposable and repeated use causes leakage. If after replacement oil stains appear under the car - stop immediately and add oil to the level.

Signs of a variator malfunction: when oil no longer helps

If the variator Murano Z51 starts to "kick" or make a grinding noise, changing the oil may be futile. Here 5 symptoms, which require diagnostics:

• 🚗 Jerks when switching (especially from "P" to "D") → worn belt or cones
• 🚗 Vibration at speeds of 80–100 km/h → pulley imbalance
• 🚗 "Check CVT" light is on → errors in solenoids or speed sensor
• 🚗 Burning smell from under the hood → overheating of oil and clutches
• 🚗 Power Loss (the car “does not move”) → belt slipping

⚠️ Attention: if the variator Murano Z51 entered "emergency mode" (rev limit to 2,500), do not try to reset the error by disconnecting the battery. This may cause the transmission to lock up. Contact service immediately!

For diagnostics, use a scanner that supports the protocol Nissan Consult. CVT error codes start with P07, P08 or P17. For example, P17F0 - overheating, P0776 - faulty pressure solenoid.

FAQ: answers to frequently asked questions from Murano Z51 owners

Can NS-3 be poured into a Murano Z50 CVT (2009-2014)?

No! B Murano Z50 CVT is used JF011Efor which the oil is recommended NS-2. NS-3 has a different viscosity and may cause belt slippage.

How much oil does a Murano Z51 need for a complete change?

For a complete replacement with flushing you will need 8–9 liters. With a partial replacement (draining through the plug) - about 4 liters.

What to do if jerking occurs after changing the oil?

Return to the service immediately! Probable reasons: incorrect oil level, fake oil or damaged filter. If you ignore the jerks, after 1–2 thousand km the variator will fail.

Is it possible to tow a Murano Z51 with a cable if the CVT is not working?

No! CVT JF017E does not have a rigid coupling between the engine and the wheels. Towing even short distances will result in belt destruction. Use only a tow truck!

How to check the oil level in the Murano Z51 CVT?

The level is checked for warmed up variator (oil temperature 60–70°C). The machine must be on a level surface and the engine must be running. Take the dipstick out, wipe it, put it back in and take it out again. The level should be between the marks HOT MIN And HOT MAX.
