Variable speed transmissions (CVT) in cars Nissan - These are complex units that require a special approach to maintenance. One of the key points is the choice of gear oil, and here the brand Kixx occupies a leading position due to the optimal price-quality ratio. But not everything is so simple: even in the Kixx line there are several types of oils for CVTs, and a mistake in the choice can lead to accelerated wear of the belt and cones after 20-30 thousand km.
In this article we will look at which oil Kixx suitable for CVTs Nissan Qashqai, X-Trail, Juke and other models, how to replace it correctly, and why even the original oil NS-3 is not always the best option. You'll also learn about the hidden specifications that manufacturers often miss, and how to avoid common replacement mistakes.
Why is Kixx oil popular for Nissan CVTs?
Brand Kixx (manufacturer - South Korean company GS Caltex) has won the trust of owners of cars with CVTs thanks to several key advantages:
- 🔬 Strict compliance with specifications: Oils Kixx CVT Fluid certified according to standards JASO 1A And Nissan NS-2/NS-3, which guarantees compatibility with most CVTs.
- 💰 The price is lower than the original: On average 20-30% cheaper than oils Nissan NS-3, without loss of quality.
- 🛡️ Wear protection: The additive package prevents belt slippage and scuffing on the cones.
- 🌡️ Stability at high temperatures: Maintains viscosity even when heated to 120°C, which is critical for CVTs in traffic jams.
However, not all oils Kixx equally good for CVTs. For example, Kixx CVT Multi Suitable for most models, but for Nissan Juke (with CVT JF015E) it is better to use Kixx CVT NS-3 - this is due to the design features of the torque converter.
⚠️ Attention: Oil Kixx ATF Multi NOT suitable for CVTs! It is intended for classic automatic transmissions and does not have the necessary anti-friction additives for the CVT belt.
Which Kixx oil is right for your CVT?
The choice of oil depends on the model of the variator and the year of manufacture of the car. Below is the compatibility table for popular models Nissan:
| Car model | CVT type | Recommended Kixx oil | Filling volume (l) |
|---|---|---|---|
| Nissan Qashqai J10/J11 (2007-2021) | JF011E |
Kixx CVT NS-2 or NS-3 | 7.8–8.2 |
| Nissan X-Trail T31/T32 (2007-2020) | JF011E / JF016E |
Kixx CVT NS-3 | 8.0–8.5 |
| Nissan Juke F15 (2010-2019) | JF015E |
Kixx CVT NS-3 (required!) | 7.2–7.5 |
| Nissan Murano Z51 (2015-2022) | JF017E |
Kixx CVT Multi (NS-3 compatible) | 8.8–9.0 |
For CVTs JF011E (installed on Qashqai And X-Trail until 2017) use is allowed Kixx CVT NS-2, but only if the car’s mileage does not exceed 100 thousand km. After this threshold it is recommended to switch to NS-3 due to increased wear of parts.

NS-2 vs NS-3: which Kixx oil is better?
The main difference between Kixx CVT NS-2 And NS-3 consists of an additive package and viscosity characteristics:
- 🔹 NS-2: More “thin” oil, optimal for new CVTs with mileage up to 80-100 thousand km. Has less resistance to oxidation.
- 🔹 NS-3: Improved formula with increased thermal stability and anti-friction additives. Recommended for CVTs with a mileage of over 100 thousand km or when used in difficult conditions (towing, off-road).
In practice, the transition from NS-2 on NS-3 often solves the problem jerks during acceleration And switching delayswhich occur due to belt wear. However, there is a nuance: if the variator already has critical wear (for example, metal shavings in the pan), even NS-3 will not save the situation - repairs will be required.
⚠️ Attention: Mix NS-2 And NS-3 strictly prohibited! This leads to oil separation and loss of lubricating properties.
For CVTs with mileage over 100 thousand km Kixx CVT NS-3 - mandatory choice, even if the manufacturer allows NS-2.
Step-by-step instructions for changing Kixx oil in a CVT
Changing the oil in a variator is a procedure that can be performed independently, but with mandatory observance of technological nuances. Below are instructions for Nissan Qashqai J11 (variator JF011E), but it is also relevant for other models with similar CVT.
Warm up the car to operating temperature (60-70°C)
Raise the car on a lift or place it on a viewing hole
Prepare a container for draining (minimum 9 liters)
Buy new oil Kixx CVT NS-3 (9 l) and filter (article 31726-31X0A)
-->
Step 1: Drain the old oil
Unscrew the drain plug on the variator pan (key 19) and drain the oil. Pay attention to the color and presence of metal shavings:
- Norm: light brown tint, free of foreign particles.
- Requires flushing: dark brown or black color, presence of chips.
If the oil has a burning smell, this indicates overheating of the variator - diagnostics of the solenoids and valve body are necessary.
Step 2: Replace the filter
Remove the variator pan (12 x 10 bolts), remove the old filter and install a new one. Pay attention to the magnets in the tray - they need to be cleaned of metal dust. It is recommended to replace the pan sealing gasket (part no. 31397-31X02).
Step 3: Flush (if necessary)
If the old oil was in poor condition, flush the variator:
1. Fill with 4 liters of new oil Kixx CVT NS-3.
2. Start the engine and let it idle for 5-7 minutes, switching the selector to the positions P-R-N-D.
3. Drain the flushing oil and fill with new oil.
Step 4: Add new oil
Fill the oil through the variator dipstick (volume - 7.8-8.2 l for Qashqai). After filling, warm up the variator to 60°C and check the level:
- The engine must be running.
- Selector in position P.
- Oil level on the dipstick is between the marks HOT MIN And HOT MAX.
If after changing the oil the variator begins to “kick”, check the level - often the problem lies in underfilling or overfilling (especially true for Nissan Juke).
Typical mistakes when changing oil and their consequences
Even experienced car owners make mistakes that can lead to CVT failure. Here are the most common ones:
- 🚫 Incomplete oil change: During a partial replacement (drain-fill), up to 30-40% of the old oil remains in the variator. This shortens the life of the new oil and accelerates belt wear.
- 🚫 Using the wrong oil: For example, fill Kixx ATF Multi instead of CVT Fluid leads to belt slippage and overheating.
- 🚫 Ignoring filter replacement: The old filter becomes clogged with wear products, which leads to a drop in oil pressure and jerking when driving.
- 🚫 Overfilling or underfilling oil: Overfilling increases the load on the pump, underfilling leads to oil starvation and bearing wear.
One of the most dangerous mistakes is washing the variator with kerosene or other solvents. This destroys the seals and washes the protective layer off the parts. If flushing is required, use only specialized fluids, e.g. Liqui Moly CVT Reiniger.
⚠️ Attention: After changing the oil in the variator Nissan X-Trail T32 (variator JF016E) be sure to adapt the variator through a diagnostic scanner (for example, Launch X431). Without this, kicks are possible when switching.
How often do you change Kixx oil in a CVT?
Manufacturer Nissan states that the CVT is filled with oil for its entire service life, but this is only true for “ideal” operating conditions. In reality, replacement intervals depend on several factors:
| Operating conditions | Recommended replacement interval | Signs that replacement is needed |
|---|---|---|
| City (traffic jams, frequent stops) | 40–50 thousand km | Jerks during acceleration, delays in switching |
| Mixed cycle (city + highway) | 60–70 thousand km | Darkening of oil, metal shavings on magnets |
| Mainly track | 80–90 thousand km | There are no obvious signs, but the oil is losing its properties |
| Extreme conditions (towing, off-road) | 30–40 thousand km | Overheating of the variator, burning smell from the oil |
For CVTs with a mileage of over 150 thousand km, it is recommended to reduce the replacement interval to 30-40 thousand km, since wear of parts accelerates oil degradation. It is also worth paying attention to oil color on dipstick:
- Light brown: Oil is in good condition.
- Dark brown/black: Replacement required.
- Milky shade: antifreeze ingress (repair required!).
What happens if you don’t change the oil in the variator?
If you ignore changing the oil in the variator, the following happens:
1. Belt wear: The oil loses its lubricating properties, the belt begins to slip, which leads to its stretching and breakage (repair cost - from 80 thousand rubles).
2. Seizure of cones: Metal particles in oil act as an abrasive, destroying working surfaces (repair involves replacing cones, price - from 120 thousand rubles).
3. Valve unit failure: Contaminated oil clogs the solenoids, which leads to chaotic shifts or complete blocking of the variator.
4. Overheating: Old oil dissipates heat less well, which leads to deformation of plastic parts (for example, bearing cages).
Owner reviews: real experience of using Kixx in a CVT
Analysis of reviews on forums (Drive2, Nissan-Club) indicates that the oil Kixx CVT NS-3 in most cases it receives positive ratings, but there are some nuances:
- ✅ Pros:
- 🔧 Eliminates jerks during acceleration (especially on runs of 100+ thousand km).
- 💧 Less burns compared to the original Nissan NS-3.
- 💰 Savings up to 3-4 thousand rubles. as a replacement compared to the original.
- ❌ Cons:
- 🔍 In some cases, after replacement, CVT hum (usually passes after 500-1000 km).
- 🛒 In small towns it can be difficult to find (most often ordered online).
- 📉 On runs over 200 thousand km, the effect is less noticeable (variator repair required).
Case Study: Owner Nissan Qashqai 2014 with mileage 130 thousand km after replacement NS-2 on Kixx CVT NS-3 noted the disappearance of jerking when switching from D on R and smoother acceleration. However, after 10 thousand km the oil darkened again - this is due to the fact that the variator was already worn out, and a partial replacement did not completely solve the problem.
FAQ: Frequently asked questions about Kixx oil in a variator
Can Kixx CVT NS-3 be mixed with Genuine Nissan NS-3 oil?
Yes, these oils are completely compatible in terms of chemical composition and tolerances. However, mixing is recommended only in emergency cases (for example, topping up on the road). For scheduled changes, it is better to use one oil.
Why did the variator become noisier after changing the oil on Kixx?
This is a normal phenomenon in the first 500-1000 km, as the new oil washes away deposits from the walls of the variator. If the noise does not disappear after 1000 km, check the oil level (overflow is possible) or the condition of the bearings.
How to check the authenticity of Kixx oil?
Original oil Kixx has:
- 🏷️ Hologram on label with logo GS Caltex.
- 📌 Serial number on the lid and bottom of the canister (must match).
- 🔍 When you shake the canister, the foam settles in 5-10 seconds (in fakes, the foam lasts longer).
Buy oil only from authorized dealers or trusted sellers.
How is the Kixx CVT Multi different from the Kixx CVT NS-3?
Kixx CVT Multi — universal oil, compatible with most CVTs (including NS-2 And NS-3). However, for CVTs Nissan with mileage over 100 thousand km it is better to use specialized Kixx CVT NS-3, since it has a reinforced additive package for worn parts.
Is it necessary to flush the variator when changing the oil?
Flushing is required if:
- 🔴 Old oil is black or has a burning smell.
- 🔴 There are a lot of metal shavings on the tray magnets.
- 🔴 The variator was previously serviced at irregular intervals (replacement every 80+ thousand km).
For flushing, use only specialized fluids (for example, Liqui Moly CVT Reiniger) and in no case kerosene!
