• 🔹 KE902-90033 — 20 liter barrel, intended for professional service stations.

⚠️ Attention: A fake is often disguised as an article KE902-90031, but differs in the quality of the plastic canister and the absence of a protective hologram on the lid. Always check the integrity of the seal before purchasing.

Differences between NS-2 and other specifications and analogues

One of the most common mistakes when choosing oil is confusion between specifications NS-2 and NS-3. These fluids have different physical properties and are not interchangeable without flushing the system. Liquid NS-2 has a higher viscosity at low temperatures and a specific friction coefficient calculated for older generations of Jatco JF011E variators.

Usage NS-3 in a box requiring NS-2, will lead to premature wear of the clutches and possible failure of the valve body. On the contrary, fill NS-2 into a unit that requires NS-3, can cause overheating and loss of elasticity of the O-rings. Therefore, the article is not just a set of numbers, but a guarantee of compatibility.

There are also high-quality analogs from third-party manufacturers that claim to meet the specification NS-2. However, original oil manufacturers Nissan We strongly recommend using only their products, since the composition of the additives is a trade secret and is definitely not reproduced by competitors. Cheap analogues may contain a low-quality base that quickly loses its properties.

• 🚫 Prohibited mix NS-2 and NS-3 without completely flushing the system.
• 🔍 Check production date on the canister; the oil has a limited shelf life.
• 💡 Use only proven analogues with official certificates of conformity.

⚠️ Attention: Some dishonest sellers may offer a “universal” fluid suitable for all types of variators. In reality, such a product often does not meet strict standards Nissan and can reduce transmission life.

Compatibility table and refill volume

To correctly select the amount of fluid, you need to know the exact volume of your car’s system. Various models Nissan require different amounts of oil, which depends on the generation of the variator and the design features of the pan. Below is a table with data for the most popular models using article number NS-2.

Car model	Engine	Filling volume (liters)	CVT type
Nissan Almera G15	1.6 (HR16DE)	4.1 - 4.3	Jatco JF015E
Nissan Teana J32	2.5 / 3.5	5.0 - 5.5	Jatco JF010E
Nissan X-Trail T31	2.0 / 2.5	4.0 - 4.5	Jatco JF011E
Nissan Qashqai J10	2.0	4.0 - 4.5	Jatco JF011E
Nissan Note E11	1.6	3.5 - 3.8	Jatco JF015E

Please note that the quantities indicated are approximate and may vary slightly depending on operating conditions and the degree of wear of the unit. With a complete replacement with flushing, the consumption may increase. Always buy fluid with a reserve so that you can adjust the level after warming up.

To accurately determine the level, you must use a dipstick or test hole, following the manufacturer's instructions. Overfilling or underfilling can lead to oil foaming and loss of pressure in the hydraulic system. Level control must be carried out with the engine running and the oil warmed up to operating temperature.

⚠️ Attention: If the oil level is below normal, this may cause air to be trapped in the pump and cause it to fail. If the level is higher, foaming and overheating of the variator is possible.

How to recognize a fake by article number and packaging

The spare parts market is oversaturated with counterfeit products, and counterfeits of original oil Nissan - not uncommon. Attackers often copy articles, but the quality of the packaging and the liquid itself leaves much to be desired. The first sign of a fake is fuzzy printing on the label, blurry fonts and the absence of security elements.

The original canister has a special lid protection that must be intact. At the bottom of the canister there must be a production date and batch number stamped on the plastic, not glued on. If you see that the date is printed with paint and is easily erased, this is a fake. Also check the seams of the canister - the original ones are smooth and neat.

The most reliable way to verify authenticity is to use the authentication system on the official website Nissan or through the dealer's mobile application. Enter article number KE902-90031 and batch serial number. If the system gives an error or indicates that the product has already been activated, you cannot purchase it.

• 🔍 Check plastic quality: the original canister does not have the smell of cheap plastic.
• 🏷️ Inspect label: no typos and correct spelling of the brand.
• 📱 Scan QR code, if present on the packaging of the new sample.

What to do if you bought a fake?

If you accidentally fill in counterfeit oil, immediately stop operating the vehicle and carry out a complete fluid change and flush the system. Contact an authorized dealer to diagnose the condition of the variator in order to exclude hidden damage to the clutches and valve body.

Level checking and replacement procedure

Fluid replacement Nissan NS-2 requires adherence to certain technology to avoid mistakes. The process begins with warming up the transmission to operating temperature (usually around 50-60 degrees Celsius). Only under such conditions can the volume of a liquid be accurately estimated, since it expands when heated.

After warming up, you need to start the engine, move the variator selector to position P or N and check the level through the inspection hole. If the level is low, add liquid in batches, waiting a couple of minutes between fills. It is important not to overdo it, as too much oil will cause it to foam and overheat.

When completely replacing, it is recommended to use the method of displacing the old fluid with a new one, as this allows you to update up to 80-90% of the oil volume. A simple replacement through the drain hole renews only about 40-50% of the fluid, since a significant part remains in the torque converter and radiator.

1. Прогрейте двигатель до рабочей температуры.
2. Переведите селектор в положение P или N.
3. Открутите контрольную пробку.
4. Дождитесь, пока масло не потечет тонкой струйкой.
5. Закрутите пробку и проверьте уровень при работающем двигателе.
