Finding the right CVT lubricant often turns into a real detective story, especially when it comes to specific standards such as Nissan NS2. Many car owners get lost in catalogs, trying to find the exact article number into a 1 liter container that would fit perfectly into their engine and gearbox. An error in selection can lead to expensive valve body repairs or premature failure of CVT clutches.
In the world of transmission fluids Nissan There is a strict hierarchy of standards, and they absolutely cannot be confused. Liquid NS2 was developed specifically for CVTs of previous generations, such as JF011E (RE0F10A), which were widely installed on models Qashqai, X-Trail and Teana. If you are looking for a specific product code to purchase, you need to rely on the official manufacturer's nomenclature to eliminate the risk of getting a counterfeit product.
Official catalog numbers and packaging
Main article number original liquid Nissan NS2 in a 1 liter canister looks like KLE520000431 (often abbreviated as KLE520000431). This is a unique identifier that is used in dealer directories around the world. However, it is important to understand that in different regions and depending on the year the batch was produced, the markings on the label itself may change slightly, although the product code itself remains the same.
In addition to the main packaging, there are alternative packaging options, which may also have different codes. For example, liquid is supplied in 4-liter cans or large barrels, but it is liter containers that are most in demand when topping up or partially replacing. The label must always clearly indicate compliance with the standard JATCO JF011E and specifications NS-2. The absence of these designations is the first sign that this is not the original.
- 🔍 Main article 1l:
KLE520000431— check its presence in the receipt upon purchase. - 🔍 Additional code:
KE90299944— found on old batches of packaging. - 🔍 Liquid color: original NS2 has a characteristic greenish tint, which does not fade over time.
⚠️ Warning: Many fakes try to imitate the code KLE520000431, but they use low-quality plastic canisters. Pay attention to the quality of the print and the absence of burrs on the cover. If the price is suspiciously low, it is almost certainly a counterfeit and will destroy your CVT.
Differences between NS1, NS2 and NS3 standards
The most common mistake when choosing transmission fluid is confusion between generations of standards Nissan. NS1 is an outdated red liquid that was used in the very first CVTs. NS2 became standard for most cars produced in 2007–2014. A NS3 is a modern fluid with a reduced coefficient of friction designed for new CVT models. Mixing them or replacing one with the other is strictly prohibited.
If the instructions for your car indicate the use NS2, and you will pour it in NS3, this will lead to belt slippage and rapid wear of the pulleys. Conversely, using NS2 in a box designed for NS3, will cause increased friction and overheating. Therefore, searching for the right article number - this is not just a formality, but a matter of operational safety.
Here are the main differences to help you navigate:
- 🛢️Color: NS1 - red, NS2 - green, NS3 - blue.
- ⚙️ Application: NS2 suitable for boxes JF011E, JF015E; NS3 for JF016E, JF017E.
- 🚫 Incompatibility: It is strictly forbidden to mix liquids of different generations, even in small quantities.

How to check the authenticity of a product by article number
The spare parts market is oversaturated with counterfeit products, especially in the segment of consumables for Japanese cars. In order not to buy a fake under the guise of an original one Nissan NS2 1 liter, you need to know several signs of authenticity. Start by checking the packaging: the canister should be made of high-quality plastic that does not have any foreign odor. The lid should fit tightly, and the protective membrane under it should be intact and even.
Pay special attention to the barcode and hologram. The original packaging often contains a holographic sticker that changes color when tilted. Also check article number on the sticker with the one listed in the catalogue. If you order oil through an online store, request a photo report before shipping. This will allow you to visually assess the quality of the print and the absence of typos in the names.
⚠️ Attention: Counterfeit products often have a thicker consistency and have a strong chemical smell. Original NS2 It has fluidity similar to water and a specific smell of fresh lubricant. If the liquid looks cloudy or has sediment, do not use it under any circumstances.
Below is a table with the main differences between the original packaging and common counterfeits:
| Sign | Original | Fake |
|---|---|---|
| Label font | Clear, smooth, no blurry edges | Sometimes blurry, with unevenness |
| Batch code | Embossed or laser printed | Printed with regular ink, finger erasable |
| Liquid color | Transparent light green | Cloudy, dark green or with sediment |
| Plastic quality | Dense, does not sag when pressed | Soft, easy to deform |
What to do if you have already bought a fake?
If you suspect that you have filled in counterfeit oil, you need to completely replace the transmission fluid as soon as possible. Flush the system with a special flush or several oil change cycles to remove any remaining bad product. Ignoring this problem can lead to a seized torque converter and breakdown of the entire transmission, the cost of repairing which can be up to 50% of the price of the car.
Replacement procedure and required volume
When replacing transmission fluid in a CVT, it is important to know the exact volume of the system. For most cars with transmission RE0F10A (JF011E) the total volume is about 7.5-8 liters, but with a partial replacement only 3-4 liters go through the drain hole. That is why buying several 1 liter canisters or one large 4 liter canister is the most economical solution. However, for a complete replacement with flushing you will need at least 5-6 liters of high-quality Nissan NS2.
The replacement procedure requires certain skills and equipment. You will need a lift, a drain pan, a funnel, and a new CVT filter. Do not attempt this job without preparation, as incorrectly checking the fluid level may result in overfilling or underfilling, which is critical to CVT performance. The level is checked with the engine running and the gearbox warm.
☑️ Preparing to change the oil in the variator
It is important to observe the temperature regime for checking the level. The fluid must be warmed up to operating temperature (usually 40–60°C), after which the engine must idle. Shift gears from P to D and back, holding each position for 3-5 seconds. Only after this can you check the level using the dipstick or control hole. If the level is below the mark LOW, add fluid, if higher HOT - drain off the excess.
Before starting work, be sure to remove the engine and crankcase protection to ensure free access to the drain plug and variator pan. Clean the area around the plug of any dirt before unscrewing it to prevent particles from getting inside the box when replacing the filter.
Features of operation and replacement intervals
Many manufacturers claim that CVTs are “maintenance-free,” but this is a myth that can cost you a lot of money. Actual oil change interval Nissan NS2 is no more than 40–50 thousand kilometers, especially if you operate the car in difficult conditions: traffic jams, towing a trailer, frequent off-road trips. Under such conditions, the oil loses its properties much faster and its color changes from green to dark brown or black.
Ignoring timely replacement leads to the accumulation of metal shavings and friction wear products. These particles clog the valve body, which causes jerking, kicking and loss of traction. Regular replacement article number KLE520000431 - this is not a whim, but a necessity to extend the life of an expensive unit. It is also recommended to change the coarse and fine filters every second oil change.
- 📅 Standard interval: 40,000 – 50,000 km.
- ⚠️ Difficult conditions: 30,000 – 35,000 km (city cycle, traffic jams).
- 🔧 Mandatory actions: Replace the filter and pan gasket with each fluid change.
Timely replacement of the original Nissan NS2 fluid is the most effective way to extend the life of the CVT and avoid costly valve body repairs. Do not skimp on consumables, as the cost of repairing the box is many times higher than the price of oil.
Alternative Manufacturers and Compatibility
Although the original liquid Nissan NS2 is the best choice; there are also high-quality analogues from third-party manufacturers on the market. However, when choosing an analogue, you need to be extremely careful and look for products that have official approval of the standard JATCO JF011E. Some brands such as Liqui Moly, Motul or Idemitsu, produce liquids compatible with the requirements Nissan, but their price can be comparable to the original.
It is important to understand that not all oils marked “for CVT” meet the standard NS2. Some manufacturers use their own specifications, which may differ in viscosity and additive package. Using the wrong fluid can lead to unstable operation of the box and increased wear. Therefore, if you decide to buy an analogue, be sure to consult a specialist or study the technical documentation.
If you still decide to use an analogue, pay attention to the following points:
- ✅ Availability of official approval of JATCO JF011E on the package.
- ✅ Matches the color of the original (green).
- ✅ Manufacturer's reputation and availability of quality certificates.
Is it possible to mix original and analogue?
Mixing the original Nissan NS2 fluid with a high-quality analogue is allowed only in extreme cases, for example, during an emergency top-up on the road. However, for a complete replacement, it is recommended to use only one type of fluid to avoid unpredictable additive reactions. It is best to drain the mixed liquid and refill with the clean original.
Frequently asked questions from owners
What is the real shelf life of the Nissan NS2?
Original liquid Nissan NS2 has a shelf life of about 5 years from the production date indicated on the label. After this period, the additives may lose their properties, and it is recommended to dispose of the oil. Canisters should be stored in a dry place, protected from direct sunlight and temperature changes.
Is it possible to add NS2 to old oil?
It is not recommended to add new fluid to old, dirty oil. This can lead to dilution of wear debris and deterioration of lubricant properties. It is best to carry out a complete replacement or at least a partial replacement followed by flushing the system.
Where can I find the original part number on the Nissan website?
