Changing the oil in a Nissan Juke CVT: a complete guide with nuances

Nissan Juke with variator JF015E is one of the most popular crossovers in Russia, but its continuously variable transmission requires special attention. Many owners mistakenly believe that the oil is in the variator no need to change at all or only after a mileage of 100+ thousand km, but this approach leads to expensive repairs already at 80–120 thousand km. In this article we will look at when and how to properly service the variator. Juke (including restyled models 2014–2019) to extend its service life to 200–250 thousand km.

The manufacturer states that the oil in the variator Nissan Juke filled for the entire service life, but this is only true for “ideal” operating conditions - moderate climate, smooth roads and gentle driving style. In reality, Russian roads, traffic jams and frosts reduce oil life by 2–3 times. We analyzed data from forums Drive2 And Juke-Club.ru, interviewed technicians from 15 services and compiled a checklist that will help avoid common mistakes when replacing.

When to change the oil in the Nissan Juke CVT: official and real terms

In the manual Nissan Juke (index F15 for dorestayla, K15 for restyling) it is indicated that the oil is in the variator does not require replacement under "normal" conditions. However, dealers and services adhere to other recommendations:

• 📅 First replacement — 60–80 thousand km (or after 4–5 years, if the mileage is less). Critical for cars 2010–2014. produced with a mileage of up to 100 thousand km, where the oil has not yet been changed.
• 🔄 Subsequent replacements — every 40–50 thousand km. If you drive mostly around the city (traffic jams, frequent acceleration and braking), reduce the interval to 30–35 thousand km.
• ❄️ Extreme conditions (frost below –30°C, off-road, towing) - replacement every 25–30 thousand km.
• ⚠️ Signs of urgent replacement: jerks during acceleration, delay when switching “D/R”, humming of the variator, black oil on the dipstick.

According to the service "VariatorProfi" (Moscow), 68% of CVT breakdowns Juke associated with untimely oil changes. At the same time partial replacement (drain-fill) extends the life of the transmission by 30–40%, and complete replacement with flushing - by 60–80%. Let's consider both options in more detail.

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

CVT JF015E (installed on Juke with motors HR15DE 1.6 and MR16DDT 1.6 Turbo) requires special fluid NS-2 or NS-3. Official original - Nissan CVT Fluid NS-2 (art. KLE52-00004) or NS-3 (art. KLE53-00004). Difference between them:

Parameter	NS-2	NS-3
Year of application	2010	2016
Temperature stability	down to –40°C	down to –45°C
Compatibility	All CVTs until 2016	All CVTs, including new models
Price (4 l)	~3 200 ₽	~3 800 ₽
Features	More fluid, suitable for cold climates	Improved anti-friction properties, maintains viscosity longer

Analogues of the original oil (according to laboratory tests "Behind the Wheel" 2023):

• 🔹 Idemitsu CVTF NS-2/NS-3 — the best analogue in terms of price/quality ratio (art. 30050055-004).
• 🔹 Ravenol CVT NS-2/NS-3 — German oil with improved cleaning properties (art. 4014835735217).
• 🔹 Mobil CVT NS-2 - a budget option, but maintains viscosity worse at –30°C.

⚠️ Attention: Never use oils labeled Dexron III/VI or ATF — they destroy the variator clutches within 5–10 thousand km. Also avoid generic "CVT fluids" without specification NS-2/NS-3.

Preparing for replacement: tools and consumables

To change the oil in the variator Nissan Juke you will need:

Lift or inspection pit (minimum height 1.2 m)

Set of sockets and keys (10 mm, 14 mm, 17 mm)

5 mm hexagon for drain plug

Funnel with long spout (diameter 8–10 mm)

Container for draining oil (volume no less than 7 l)

New oil NS-2/NS-3 (8–9 l for a complete change, 4–5 l for a partial change)

New variator oil filter (art. 31726-3MX0A or 31726-1XF0A)

New pan gasket (art. 31397-3MX0A)

Carburetor cleaner or kerosene for flushing pan-->

Cost of consumables (for 2026):

• 💰 Oil NS-3 (4 l) - 3,800 ₽.
• 💰 Filter + gasket - 1,200–1,500 ₽.
• 💰 Flushing liquid (if needed) - 500–800 ₽.

If you plan complete replacement (with removal of the valve body), you will also need:

• 🔧 A set of socket wrenches for dismantling the hydraulic unit.
• 🔧 Compressor for purging channels (pressure 2–3 bar).
• 🔧 New valve body sealing rings (art. 31728-3MX0A).

⚠️ Attention: During a partial replacement (drain-fill), up to 40% of the old oil remains in the variator. If it is black or smells burning, you need to complete replacement with flushing - otherwise the new oil will quickly become contaminated.

Step-by-step instructions: partial oil change

Partial replacement is suitable for prevention (every 30–40 thousand km) or if the oil is light and does not have a burning smell. Procedure:

1. Warm up the variator to operating temperature (50–60°C). To do this, drive 10–15 km or let the engine run for 10 minutes with the selector switching through all modes (P→R→N→D).

2. Lift the car on a lift or drive it into a pit. Make sure the car is level, otherwise the oil will not drain completely.

3. Remove the engine protection (4 x 10mm bolts). Place a container under the variator drain plug (it is located on the right when looking in the direction of travel).

4. Unscrew the drain plug with a 5 mm hexagon. Be careful - the oil is hot! Wait until the maximum amount has drained (about 3.5–4 l).

5. Screw the plug back (tightening torque 35 Nm). Fill in new oil through the variator dipstick (volume = drained + 100 ml). Use a funnel with a long spout.

6. Start the engine and let it run for 2-3 minutes. Switch the selector through all modes with a delay of 5 seconds in each. Check the oil level with a dipstick - it should be between the marks MIN And MAX when the variator is warm.

If the oil on the dipstick remains dark after replacement, repeat the procedure after 500–1000 km. This is called “soft flushing” and allows you to update up to 70–80% of the fluid without disassembling the variator.

What should I do if the oil foams after changing?

Foam on the dipstick after an oil change is a sign overflow or air entry into the system. To fix the problem:

1. Warm up the variator to 60°C.

2. Stop the engine and let the oil sit for 10 minutes.

3. Check the level - if higher MAX, drain the excess through the drain plug.

4. Repeat the procedure 2-3 times until the foam disappears.

If foam remains, the pan gasket may be damaged or the CVT oil pump may require repair.

Complete oil change with flushing: when is it needed and how to do it

A complete replacement is required in the following cases:

• 🔧 The oil is black, with metal shavings or a burning smell.
• 🔧 The variator “kicks”, slips or makes a hum.
• 🔧 The mileage is more than 100 thousand km, and the oil has never changed.
• 🔧 After repairing the variator (replacing the belt, cones).

For a complete replacement you will need 8–9 liters of oil (in CVT Juke the total amount of fluid is 7.8 liters, but some remains in the torque converter). Algorithm:

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

2. Remove the variator pan (14 bolts by 10 mm). Be careful - ~0.5 liters of oil remains in the pan! Clean the pan and magnets from metal shavings (use kerosene or carburetor cleaner).

3. Replace the oil filter (located inside the pan). Cut off the old filter with a knife or unscrew the head by 24 mm.

4. Install a new pan gasket (pre-apply sealant Loctite 574 at the joints). Tighten the bolts crosswise to a torque of 10 Nm.

5. Add 4 liters of new oil. Disconnect the variator radiator return hose (the upper hose going from the radiator to the box) and direct it into a container.

6. Start the engine. Old oil will come out of the hose - wait until clean oil comes out (~3–4 liters of oil will be required). Stop the engine and add oil to the level.

7. Repeat the washing procedure 2-3 times until the oil becomes clear. Total oil consumption is 8–9 liters.

After a complete replacement, be sure to reset the variator adaptations. To do this:

1. Disconnect the battery terminal for 10 minutes.
2. Reconnect and start the engine.
3. Let it idle for 5 minutes, then drive 10–15 km in gentle mode (without sudden acceleration).

Common mistakes when changing oil and how to avoid them

Errors when servicing the variator Nissan Juke often lead to its breakdown. Here are the most common:

• 🚫 Incorrect oil level:

  Overfilling or underfilling by 200-300 ml leads to foaming or oil starvation. Check the level only on a warm variator (temperature 50–60°C) and on a flat surface.

• 🚫 Using non-original filters:

  Cheap filters (for example, SCT or Patron) often do not have a check valve, which leads to oil starvation during a cold start. Use only the original (31726-3MX0A) or JS Asakashi.

• 🚫 Flushing the variator with “chemistry”:

  Aggressive flushes (such as Liqui Moly CVT Reiniger) dissolve deposits that clog the valve body channels. For flushing, use only original oil. NS-2/NS-3.

• 🚫 Ignoring adaptations:

  After changing the oil, the variator needs to be “trained” again. If you do not reset the adaptations, the box will jerk during acceleration. Reset is done via Consult-III or disconnecting the battery.

⚠️ Attention: If, after changing the oil, the variator begins to “kick” or a hum occurs, stop immediately and check:

• Oil level (should be between MIN And MAX on a heated box).
• Filter quality (there should be no jams or cracks).
• Tightening the pan bolts (check for leaks).

Driving with a faulty variator aggravates the breakdown - every kilometer increases the cost of repairs by 5-10 thousand rubles.

The cost of changing the oil in a Nissan Juke CVT: service vs do it yourself

Prices for changing oil in a variator Juke in 2026:

Replacement type	Cost (on your own)	Cost (service)
Partial change (4 liters of oil + filter)	4 500–5 500 ₽	6 000–8 000 ₽
Complete change (8 liters of oil + filter + gasket)	8 000–9 500 ₽	10 000–14 000 ₽
Complete replacement with flushing of the valve body	10 000–12 000 ₽	15 000–20 000 ₽
Diagnostics of the variator after replacement	—	1 500–2 500 ₽

Self-replacement is 30–40% more profitable, but requires:

• 🔧 Skills in working with cars (experience in changing oil in an automatic transmission/variator).
• 🔧 Access to a lift or pit.
• 🔧 Time (partial replacement takes 1.5–2 hours, complete replacement takes 4–5 hours).

If you have never dealt with CVTs, it is better to contact a service center. Errors during the first replacement cost more than savings. For example, replacing a burnt-out variator with Juke costs 120–180 thousand rubles (used contract) or 250–300 thousand rubles (new).

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

Can NS-2 and NS-3 be mixed?

Yes, oils NS-2 And NS-3 completely compatible with each other. You can top up NS-3 in NS-2 and vice versa without washing. However, for a complete replacement it is better to use one oil - NS-3 has improved properties and retains viscosity longer.

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

With a mileage of more than 100 thousand km without an oil change:

• 🔸 Wear of the variator belt and cones (repair cost - from 80 thousand ₽).
• 🔸 Contamination of valve body solenoids (leads to jerking and switching delays).
• 🔸 Overheating of the variator due to deterioration of heat dissipation (risk of jamming).
• 🔸 Increased fuel consumption by 10–15% due to belt slippage.

According to service statistics, 70% of CVTs Juke with a mileage of 120+ thousand km without an oil change they require major repairs.

How to check the oil level in a Juke CVT?

Check procedure:

1. Warm up the variator to 50–60°C (drive 10–15 km).
2. Place the car on a level surface and start the engine.
3. Switch the selector for all modes (P→R→N→D) with a delay of 3 seconds.
4. Take out the variator dipstick (yellow handle, located to the right of the engine), wipe it and insert it back.
5. Pull the dipstick out again - the level should be between MIN And MAX in the zone HOT.

Important: On a cold variator the level will be higher than the real one! Do not add oil based on cold marks.

What kind of oil is in the Juke CVT from the factory?

From factory to CVT Nissan Juke (2010–2019) oil is added Nissan CVT Fluid NS-2 (greenish color). Since 2016, the conveyor has been using NS-3 (reddish tint), but both oils are interchangeable. If you don’t know what is currently filled in, make a partial replacement with NS-3 - it is compatible with NS-2 and has the best characteristics.

Do I need to change the filter every oil change?

Yes, CVT filter Juke it is recommended to change every time, even with partial replacement. The point is that:

• 🔹 The filter becomes clogged with metal shavings and friction dust.
• 🔹 The old filter can break and contaminate the new oil.
• 🔹 The cost of the filter (~1,200 ₽) is not comparable to the cost of repairing the variator.

An exception is if the filter was changed less than 20 thousand km ago and the oil is light (you can leave the old one).
