CVT Nissan Qashqai 2019 (model J11 with engines HR16DE or MR20DD) requires special attention to the transmission fluid. Unlike classic automatic transmissions, a CVT JF017E (installed on most versions) is sensitive to the quality and level of oil: its degradation leads to belt slipping, jerking and premature wear of the cones. The manufacturer claims that the fluid in the variator is filled “for its entire service life,” but in practice Changing the oil every 60–90 thousand km extends the life of the gearbox by 30–50% - this is confirmed by diagnostic data from service centers.
If you notice that the car accelerates worse, vibrations appear when switching modes D/R or fuel consumption has increased - these are direct signs of “tired” oil. In this article we will look at how to change the fluid in the variator yourself. Qashqai 2019, which oil to choose (including analogues), and we will reveal 3 critical errors, which 80% of car owners allow for the first replacement. We will also provide an oil compatibility table and show you how to reset the fluid aging counter through CONSULT-III Plus (if you have access to diagnostic equipment).
What kind of oil to fill in the variator Nissan Qashqai 2019
Original fluid for variator Qashqai J11 — Nissan CVT Fluid NS-3 (article KE909-99932). This is a synthetic oil with improved anti-friction additives, designed specifically for CVTs. Jatco series JF0xx. However, there are high-quality analogues on the market that can be used without risk to the box:
- 🔹 Idemitsu CVTF NS-3 - a complete analogue of the original, produced at the same plant in Japan (article no.
30050036-025). - 🔹 Ravenol CVT NS-3 — German oil with extended service life (suitable for severe operating conditions).
- 🔹 Mobil CVT NS-3 - a budget option, but with good reviews from the owners Qashqai after 100+ thousand kilometers.
- 🔹 Motul Multi CVT - universal liquid, compatible with NS-2/NS-3, but requires more frequent replacement (every 50 thousand km).
⚠️ Attention: Never use oils labeled NS-2 (For example, Nissan NS-2 or Mitsubishi CVT Fluid J1) - they have a different additive package and can cause belt slippage. Also avoid "generic" ATF fluids (eg. Dexron VI or Mercon LV), even if the seller assures of their compatibility.

When to change the oil in a variator: signs and intervals
Official regulations Nissan does not provide for changing the oil in the variator Qashqai 2019, but this rule only applies to “ideal” operating conditions: moderate climate, smooth roads and gentle driving style. In reality, there are clear signs that it’s time to update the fluid:
- 🚗 Jerks during acceleration (especially at speeds of 40–60 km/h).
- 🔥 CVT overheating (temperature above 100°C on the on-board computer display).
- 🛢️ Dark oil color (black or brown liquid with a burning smell is visible on the dipstick).
- 🔊 Hum or whistle from the box area when coasting.
Recommended replacement intervals:
- 🔄 Partial replacement (30–40% volume): every 30–40 thousand km.
- 🔄 Complete replacement (hardware or manual washing): every 60–90 thousand km.
If you frequently drive in traffic or tow a trailer, reduce your replacement interval by 20 to 30%. CVT JF017E is especially sensitive to overheating, and old oil loses thermal conductivity.
Tools and consumables for oil change
To change the oil in the variator yourself Nissan Qashqai 2019 you will need:
New oil (8–9 liters for a complete change)
Variator filter (article no. 31726-3M50A)
Pan gasket (item no. 31397-3M500 or 31397-3M50A)
8 mm square wrench for drain plug
10mm socket for pan bolts
Funnel with a narrow neck (diameter up to 15 mm)
Oil syringe (if there is no special pump)
Lint-free rags and drainage container (minimum 5 l)
Diagnostic scanner (optional, for oil meter reset)
-->
⚠️ Attention: Do not use metal brushes to clean the magnets in the tray - they may leave particles that will then end up in the valve body. It is better to wash them in kerosene or a special cleaner (for example, LIQUI MOLY Getriebe-Reiniger).
If you are planning complete replacement (and not partial), you will additionally need:
- 🔧 Washing plant (can be rented at a car service station).
- 🔄 Additional 4–5 liters of oil for washing.
- 📊 Scanner for resetting the oil aging counter (For example, Launch X431 or Delphi DS150E).
Step-by-step instructions for changing the oil in the variator
The process of changing the oil in the variator Qashqai 2019 consists of several stages. If this is your first time doing this, prepare photos of each step in advance - this will help you avoid mixing up the parts during assembly.
1. Drain old oil
1. Warm up the engine to operating temperature (60–80°C) - this will reduce the viscosity of the oil and allow the maximum volume to drain.
2. Raise the car on a lift or place it on a viewing hole. Remove the crankcase protection (if equipped).
3. Place a container under the drain plug (it is located on the variator tray). Unscrew the plug with an 8 mm square wrench. Be careful - the oil will be hot!
4. Wait until it drains completely (about 3-4 liters). If the oil is dark with metal shavings, this is a signal of critical gearbox wear.
2. Replacing the filter and cleaning the pan
1. Unscrew all the pan bolts (10 mm head) and carefully remove it. Inside you will see two magnets - clean them of metal dust.
2. Remove the old filter (it is secured with 3 bolts). Install a new filter (part number 31726-3M50A) and replace the pan gasket.
3. Wash the pan with kerosene or a special cleaner. Wipe dry with a lint-free cloth.
What to do if there are a lot of chips on the magnets?
If you find large metal particles (more than 1 mm) on the pan magnets, this is a sign of wear on the cones or the variator belt. In this case, changing the oil can only temporarily improve the situation - get ready to repair the gearbox in the next 20-30 thousand km.
3. Filling with new oil
1. Place the pan in place and tighten the bolts crosswise (tightening torque: 8–10 Nm).
2. Fill in new oil through the filler hole (located on top of the variator, under the hood). A partial replacement will require about 4 liters.
3. Start the engine and warm it up to operating temperature. Alternately switch the variator selector to all positions (P → R → N → D), holding each for 5–10 seconds.
4. Check the oil level with a dipstick (it should be between the marks MIN And MAX when the box is warm). Top up if necessary.
After changing the oil, be sure to reset the fluid aging counter using the diagnostic scanner. Without this, the box will “think” that the oil is old and may incorrectly adjust the pressure in the valve body.
Partial vs full replacement: which is better?
Many owners Qashqai 2019 They argue which method of changing the oil in a variator is more effective. Let's look at the pros and cons of each:
| Criterion | Partial replacement | Complete replacement (hardware) |
|---|---|---|
| Cost | Low (4–5 l of oil + filter) | High (8–9 liters of oil + work) |
| Efficiency | 30–40% of oil is replaced | 90–95% of oil is replaced |
| Time | 30–60 minutes | 1.5–2 hours |
| Risk of box damage | Minimum | Medium (if not properly washed) |
| Recommendation | Every 30 thousand km | Every 60–90 thousand km |
If you have never changed the oil in a CVT, start with double partial replacement: For the first time, drain the old oil and fill with new oil, drive 500–1000 km, then repeat the procedure. This will allow you to renew up to 60–70% of the liquid without risk to the box.
After a complete oil change, avoid sudden acceleration and towing for the first 200–300 km. The new oil should be evenly distributed throughout all channels of the valve body.
Typical mistakes when changing oil in a variator
Even experienced car owners make mistakes that can lead to CVT failure. Here are the most common:
- ❌ Overfilling or underfilling oil. The optimal level is between
MINAndMAXon the dipstick when the box is warm. Exceeding the level leads to foaming of the oil, and underfilling leads to oil starvation. - ❌ Using the wrong oil. For example, fill NS-2 instead of NS-3 or universal ATF fluid. This causes belt slippage and accelerated wear of the cones.
- ❌ Ignoring filter replacement. An old filter becomes clogged with wear products and does not allow enough oil to pass through, which leads to increased pressure in the system.
- ❌ Failure to comply with temperature conditions. Pouring oil into a cold box or checking the level on unheated fluid gives inaccurate results.
- ❌ No oil meter reset. Without this, the box continues to operate in “emergency” mode, considering the oil to be old.
⚠️ Attention: If after changing the oil the variator starts to jerk or makes noise, stop immediately and check the level. Air may have entered the system (for example, due to improper syringing). In this case, you need to repeat the drain/fill procedure.
FAQ: Frequently asked questions about changing the oil in the Qashqai 2019 CVT
Is it possible to mix different oils in a variator?
Mix oils NS-3 from different manufacturers (for example, Nissan And Idemitsu) is possible, since they have the same base and additive package. However, it is not recommended to mix NS-3 with NS-2 or other types of CVT fluids - this will lead to a chemical reaction and loss of properties.
How to check the oil level in the variator?
1. Warm up the box to 60–80°C (drive 10–15 km).
2. Place the car on a level surface and start the engine.
3. Switch the selector to all positions (P-R-N-D) and return to P.
4. Take out the dipstick (yellow handle next to the battery), wipe it and insert it back.
5. Take out the dipstick again - the level should be between MIN And MAX in the zone "HOT".
What happens if you don’t change the oil in the variator?
If you ignore changing the oil in the variator Qashqai 2019 the following processes occur:
- 🔥 Overheating of the box due to loss of thermal conductivity of the oil.
- 🔧 Accelerated wear of the belt and cones (jerks appear during acceleration).
- 💥 Clogging of valve body channels with wear products, which leads to increased pressure and breakdown of solenoids.
- 🚗 Ultimately - replacing the variator assembly (cost from 250,000 rubles).
Average variator resource JF017E without oil change - 120–150 thousand km. With regular maintenance, this figure increases to 200–250 thousand km.
Is it necessary to flush the variator when changing the oil?
Flushing the variator is recommended only in two cases:
- 🔄 If the oil has not been changed for more than 100 thousand km and has a dark color with a burning smell.
- 🔧 If a large amount of metal shavings is found in the pallet.
For rinsing use only original NS-3 oil (not special flushing fluids!). The process looks like this: drain the old oil, fill in new oil, drive 500 km, then repeat the change.
Is it possible to change the oil in the variator yourself or is it better to go to a service center?
Even a beginner can perform a partial oil change (without removing the pan) - it is no more difficult than changing the engine oil. However for complete replacement When flushing the system and resetting the oil meter, it is better to contact a service center, as you will need:
- 🔧 Special equipment for washing.
- 📊 Diagnostic scanner for resetting the counter.
- 👨🔧 Experience with CVTs Jatco (for example, knowing the tightening torque of the pallet bolts).
The cost of a complete replacement during service is from 5,000 to 8,000 rubles (excluding oil).
