CVT Nissan Qashqai J11 (2019) is one of the most reliable in the line, but only subject to timely maintenance. Many owners mistakenly believe that CVT oil filled for the entire service life, but the manufacturer clearly regulates its replacement every 60–90 thousand km (depending on operating conditions). Neglecting this procedure leads to overheating of the variator belt, accelerated wear of the cones and breakdown of the gearbox costing from 200 thousand rubles.
In this article we will look at how to change the oil in a variator yourself. Qashqai 2019 with engines 1.3 DIG-T (HR13DDT) and 2.0 (MR20DD), what tools and consumables will be needed, and we will also cut hidden nuances, which are silent about in the official manuals. Let's take a closer look at the choice of oil - why? NS-3 better NS-2, and what happens if you mix them.
Why does the Qashqai 2019 CVT require regular oil changes?
Structurally, the variator Jatco JF017E, installed on Qashqai J11, differs from classic automatic transmissions in the absence of fixed gears. Instead, the gear ratio changes smoothly due to steel belt And bevel pulleys. The oil here performs three functions at once:
- 🔧 Lubrication rubbing surfaces (belt, bearings, cones).
- 🔥 Heat dissipation — the variator heats up more than the automatic transmission due to belt slippage.
- 🛠️ Torque transmission through a torque converter (in some modes).
Over time, the oil loses its properties: it accumulates wear products (metal shavings, friction dust), additives oxidize, viscosity decreases. This leads to:
- ⚠️ Jerks during acceleration (especially when cold).
- ⚠️ Delays when switching modes
D/R. - ⚠️ Loss of power and increased fuel consumption.
- ⚠️ Overheating of the box (risk of belt failure).
⚠️ Attention: If the variator oil appears burnt smell or it has changed color to dark brown - this is a sign of critical wear. In this case, not only an oil change is required, but also a pulley/belt diagnosis.
- Every 60 thousand km
- Every 90 thousand km

What kind of oil to fill in the variator Nissan Qashqai 2019
The manufacturer recommends using only original oil Nissan CVT Fluid NS-3 (art. KE909-99932). This is a synthetic fluid with improved anti-friction and heat-resistant properties, designed specifically for CVTs Jatco last generation. Alternatives:
| Brand | Article | Compatibility | Notes |
|---|---|---|---|
| Nissan CVT Fluid NS-3 | KE909-99932 |
100% | Original, best choice |
| Mitsubishi CVT Fluid J4 | MZ320266 |
Yes | Analogous to NS-3, used in Outlander |
| Idemitsu CVTF | 30450025 |
Yes | Japanese oil, similar in properties |
| Ravenol CVT Fluid J1 | 4014835755307 |
Partially | Suitable for partial replacement |
Important: Oil NS-2 (art. KE908-99932) doesn't fit for Qashqai 2019! It is intended for older CVTs (before 2013) and has a different viscosity characteristic. Mixing NS-2 And NS-3 leads to:
- 🔴 Loss of smoothness of switching.
- 🔴 Accelerated belt wear.
- 🔴 Risk of blocking pulleys.
Before buying oil, check its authenticity: on the original canister Nissan NS-3 there should be a holographic sticker with a serial number, which can be checked on the manufacturer’s website.
Change intervals: when to change the oil in the variator
Official regulations Nissan for Qashqai J11 (2019 onwards) provides for changing the oil in the variator:
- 📅 Every 60 thousand km — when used in difficult conditions (city traffic, towing, off-road).
- 📅 Every 90 thousand km - when driving quietly on the highway.
However there is hidden factors, shortening the interval:
- 🌡️ Frequent overheating (driving in traffic jams, towing a trailer).
- 🏔️ Highlands — the variator operates with increased load.
- ❄️ Operation at −25°C and below — the oil thickens, lubrication deteriorates.
- 🚗 Aggressive driving style (sharp acceleration, braking).
How to determine when it's time to change the oil ahead of schedule:
- 🔍 Color: fresh oil - transparent with an amber tint; if it becomes dark, replacement is required.
- 👃 Smell: A burnt aroma indicates overheating.
- ⚙️ Box behavior: jerks, delays when switching
P→D.
⚠️ Attention: If the variator dipstick shows metal shavings - This is a sign of wear on the pulleys or bearings. In this case, changing the oil can only temporarily delay the repair.
What happens if you don’t change the oil in the variator?
If you ignore changing the oil in the variator Qashqai 2019 after 120–150 thousand km, irreversible consequences arise:
- Destruction of the belt (replacement cost - from 50 thousand rubles).
- Seizures on the pulley cones (repair involves replacing the variator assembly).
- Locking the box in emergency mode (requires a tow truck).
In 80% of cases, such breakdowns lead to the purchase of a contract variator (from 180 thousand rubles).
Preparing for replacement: tools and consumables
To completely change the oil in the variator Nissan Qashqai 2019 you will need:
Lift or inspection hole|TORX T30 star wrench for drain plug|Operation container (minimum 7 l)|Funnel with narrow spout|New oil NS-3 (9–10 l for a complete replacement)|New variator filter (art. 31726-1XF0A)|Pan gasket (art. 31397-1XF0A)|Sump tray cleaner (e.g. LIQUI MOLY Getriebe-Reiniger)|Lint-free rags|Gloves and glasses-->
Pay special attention variator filter. B Qashqai 2019 two types are used:
- Coarse filter (mesh in the tray) - reusable, washable.
- Fine filter (inside the box) - disposable, replaced at every oil change.
Important: If you are planning partial replacement (drain-fill), 4–5 liters of oil is enough. For complete replacement (with flushing) you will need 9–10 liters and special equipment (for example, a Wynn’s Transerve II).
Don't skimp on filters! Cheap non-original filters can delaminate and clog the oil receiver, which will lead to oil starvation of the variator.
Step-by-step instructions for changing the oil in the variator
The process of changing the oil in the variator Nissan Qashqai 2019 consists of several stages. Let's consider complete replacement (recommended method):
Step 1: Drain the old oil
1. Warm up the engine to operating temperature (60–70°C) so that the oil becomes less viscous.
2. Raise the car on a lift or drive it into a pit. Make sure the car is parked strictly horizontal.
3. Unscrew drain plug (key TORX T30) and drain the oil into a container. Attention: the oil will be hot!
4. After draining, unscrew variator tray (14 bolts per 10 mm). Be careful - ~0.5 liters of oil remains in the pan.
Step 2: Cleaning the pan and replacing filters
1. Remove the old pan gasket and clean the surface of any remaining sealant.
2. Rinse the tray and magnets (they collect metal shavings) with an automatic transmission cleaner (for example, LIQUI MOLY).
3. Replace fine filter (located inside the box, you need to unscrew 3 bolts).
4. Rinse strainer in the tray and install it back.
Step 3: Add new oil
1. Install a new pan gasket (coat with sealant Loctite 574) and tighten the bolts crosswise.
2. Through filler hole (located on top, under the hood) fill in ~4.5 liters of new oil NS-3.
3. Start the engine and alternately switch the variator selector to all positions (P→R→N→D), holding each for 5 seconds. This will circulate the oil through the system.
4. Repeat draining and filling 2 more times to replace 90% oil.
5. After final filling, check the level according variator dipstick (must be between marks MIN And MAX on a heated box).
If after replacement the variator starts to “kick”, this is normal for the first 50–100 km. The new oil has different friction properties, and the box needs time to adapt.
Step 4: Reset the oil aging counter
After changing the oil, it is necessary to reset the aging counter in the variator control unit. This can be done:
- 🔧 Through diagnostic scanner (For example, Launch X431 or Delphi).
- 🔧 Manually (only for partial replacement):
- Turn on the ignition (do not start the engine).
- Press the gas pedal all the way and hold for 10 seconds.
- Release the pedal, turn off the ignition.
- Repeat 3 times.
⚠️ Attention: If you do not reset the counter, the control unit will assume that the oil is old and may incorrectly adjust the pressure in the valve body, which will lead to jerking.
Common mistakes when changing oil
Even experienced craftsmen make mistakes that reduce the life of the variator. Here are the most critical ones:
- 🚫 Incomplete oil drain - if you do not wash the box, the old oil will mix with the new one and its properties will deteriorate.
- 🚫 Using non-original filters — cheap filters can fall apart and clog the oil receiver.
- 🚫 Overfilling or underfilling oil — both lead to foaming and oil starvation.
- 🚫 Ignoring magnets in the tray - if they are not cleaned, the shavings will fall back into the box.
- 🚫 Changing the oil on a cold variator — viscous oil is not completely drained.
Another common mistake is use of flushing fluids (For example, HI-GEAR). In the variator Qashqai apply them it's impossible, since they aggressively attack rubber seals and can wash the protective layer off the cones.
What to do if you pour oil into the variator?
If the oil level is above the mark MAX on the dipstick:
1. Pump out the excess with a syringe through the filler hole.
2. Warm up the box to 60°C and check the level again.
3. If the oil foams, a complete replacement is required, since foam impairs lubrication.

| Pan gasket | 500–800 | Original 31397-1XF0A |
Replacing it yourself will cost 6,000–9,000 rubles (including oil and consumables). In the service the price will increase to 10,000–15,000 rubles, but you will receive a guarantee on the work.
Where is the best place to change:
- ✅ Official dealer - guarantee, but high price.
- ✅ Specialized CVT service - the best option.
- ❌ Garage craftsmen — the risk of running into poor-quality work.
FAQ: Frequently asked questions about changing the oil in the Qashqai 2019 CVT
Can NS-2 oil be used instead of NS-3?
No! NS-2 has a different viscosity characteristic and is not suitable for CVTs Jatco JF017E, installed on Qashqai 2019. Its use will lead to belt slippage and accelerated wear of the pulleys.
How much oil is needed for a complete change?
For complete replacement (with flushing) required 9–10 liters oils NS-3. When partial replacement (drain-fill) 4–5 liters is enough.
Do I need to change the filter every oil change?
Yes, fine filter (art. 31726-1XF0A) it is recommended to change at every oil change. The mesh filter in the pan can be washed and reinstalled.
What happens if you don’t reset the oil aging counter?
The CVT control unit will assume that the oil is old and may incorrectly regulate pressure in the hydraulic unit. This will manifest itself in jerks during acceleration and deterioration in the smoothness of switching.
Is it possible to mix different oils in a variator?
Mix NS-3 with other oils (for example, NS-2 or universal ATF) strictly prohibited. This will lead to a change in viscosity and loss of lubricating properties.
