Modern Japanese cars require special attention to the engine lubrication system, especially when it comes to the brand Nissan. Owners of popular models such as Qashqai, X-Trail or Teana, are often faced with the dilemma of choosing lubricants. The manufacturer strongly recommends using original products, and one of the key solutions in the line is Nissan Genuine Oil NS-2 engine oil.
This specific product was developed by the concern's engineers specifically to work with gasoline engines equipped with a CVTCS variable valve timing system. The wrong choice of viscosity or standard can lead to reduced power, increased fuel consumption and even failure of expensive engine components. Therefore, understanding the composition and characteristics of NS-2 oil becomes critical for the long-term operation of your vehicle.
Characteristics and purpose of the original oil
Oil NS-2 is a synthetic product with a viscosity of 5W-30 that meets strict environmental standards. Its main task is to provide reliable protection of rubbing pairs at low temperatures and maintain a stable oil film under high loads. The formula includes special additive packages that prevent the formation of deposits and soot in fuel combustion zones.
Particular attention should be paid to compatibility with engine management systems. The product is designed so as not to interfere with the operation of electronic sensors and variable valve timing systems. Usage original oil NS-2 guarantees that the VVT-i valve will operate smoothly, without delays and knocks characteristic of low-quality analogues. It is this property that makes it the preferred choice for HR and MR series engines.
- 🔧 Perfect compatibility with engines Nissan HR16DE and MR20DE.
- 🛡️ High oxidation resistance with long replacement intervals.
- ❄️ Excellent starting properties at temperatures down to -35°C.
Technical differences and model compatibility
Many owners mistakenly believe that any oil with a viscosity of 5W-30 will suit their car. However Nissan NS-2 specification implies the presence of a unique additive package adapted to the requirements of the manufacturer. This is especially important for models with a CVT, where compatibility requirements for engine fluids and oils may be cross-functional.
For cars Nissan Qashqai and Teana With gasoline engines, the use of the recommended product is a prerequisite for maintaining the warranty. If you use third party brands, make sure they are API SN or ILSAC GF-5 approved, but the original always remains the standard of quality. The table below shows the main parameters of the product for clarity.
| Parameter | Meaning | Comment |
|---|---|---|
| Viscosity (SAE) | 5W-30 | Universal all-season viscosity |
| Base type | Synthetics | Fully synthetic base |
| Quality standard | API SN / ILSAC GF-5 | High level of protection and cleanliness |
| Density at 15°C | 0.85 g/cm³ | Typical for synthetic oils |
| Flash point | 220°C | High thermal stability |
⚠️ Attention: The use of oils with a viscosity of 5W-40 or 10W-40 in modern engines Nissan can lead to increased fuel consumption and difficult starting in winter, since hydraulic pushers and phase shifters are designed for a more liquid medium.

Replacement process and necessary tools
Oil change NS-2 - a procedure that you can perform yourself if you have a minimum set of tools and a lift or pit. It is important not only to drain the old fluid, but also to prepare the system to receive the new one. It is necessary to pre-warm the engine to operating temperature so that the oil becomes more fluid and comes out with the maximum amount of wear products.
Before starting work, be sure to check the condition of the drain plug and gasket. If the threads are stripped or the gasket is deformed, leaks may result. Also, do not forget to prepare a new oil filter, since using an old filter will negate the effect of changing fresh oil. To access the drain hole, it is often necessary to remove the crankcase protection.
☑️ Preparing for an oil change
The sequence of actions is strictly regulated: draining the waste, replacing the filter, pouring new oil through the neck. After filling, you need to start the engine and let it idle for about 3-5 minutes. This will help the oil pump prime the system and check for leaks. After stopping the engine, you need to wait 5-10 minutes and check the level with a dipstick.
⚠️ Attention: Never pour oil above the MAX mark on the dipstick. Excessive pressure in the crankcase can push out the crankshaft and camshaft seals, leading to costly repairs.
What to do if you overfilled the oil?
If the level exceeds the maximum mark, it is necessary to pump out the excess with a syringe through the neck or through the hole in the oil pressure sensor. Ignoring overfilling can lead to oil foaming and loss of its lubricating properties, which can lead to engine seizure.
Signs of the need for urgent replacement
Although the manufacturer sets scheduled replacement intervals, actual operation may make adjustments. In a city with constant traffic jams, an interval of 10,000 km may be too long. Oil NS-2 loses its properties faster when operating in “start-stop” mode, when the engine does not have time to warm up, but operates under load.
The need for unscheduled replacement can be determined by several indirect signs. This is a change in the color of the oil on the dipstick (it becomes black and cloudy), the appearance of extraneous noise in the engine, or the smell of burnt oil in the cabin. Also pay attention to the behavior of the car: a decrease in acceleration dynamics and an increase in fuel consumption may indicate degradation of lubricating properties.
- 🛢️ Change in color and smell of oil on the dipstick.
- 🔊 The appearance of hydraulic compensators knocking when cold.
- 📉 Increased fuel consumption for no apparent reason.
Always store the remaining oil after an oil change in a clean, labeled container. This will be useful for topping up if necessary or for checking quality at the stand in case of a dispute with the service.
Original or analogue: what to choose?
The auto parts market is overflowing with offers of analogues, which are positioned as an equivalent replacement for the original product. However NS-2 specification is a proprietary development Nissan, and finding an exact analogue is extremely difficult. Many brands offer oils with a viscosity of 5W-30, but their additive package may differ, which affects the operation of the VVT system.
If you decide to save money and buy an analogue, choose only proven global brands that have official approvals API SN Plus or ILSAC GF-6. But remember that skimping on oil can lead to higher engine repair costs in the future. Original oil Nissan is guaranteed to meet all the requirements of the manufacturer's engineers.
It is worth noting that counterfeits of the original oil are common. When purchasing, pay attention to the integrity of the packaging, the quality of label printing and the presence of protective holograms. Purchasing from large chain stores or official dealers reduces the risk of purchasing counterfeit goods. The original oil always has a unique article number and barcode, which can be checked on the manufacturer’s website.
⚠️ Attention: Cheap analogues of unknown brands often contain a low-quality base, which quickly oxidizes and loses viscosity, which leads to increased wear of engine parts after 3-4 thousand kilometers.
Choosing the original NS-2 oil is an investment in the long life of the engine, while dubious analogues can lead to unpredictable consequences.
Owner Frequently Asked Questions (FAQ)
Can NS-2 oil be mixed with other brands?
In an emergency situation, when the oil level is critically low, adding a small amount of another high-quality oil is acceptable. However, after this, it is recommended to carry out a complete oil and filter change as soon as possible to avoid chemical reactions between different additive packages.
How often do you need to change NS-2 oil in the city?
When operating in urban environments with frequent traffic jams and short trips, the optimal replacement interval is 7,000 - 8,000 km. This will ensure that the protective properties of the oil are maintained and the engine clean.
Is NS-2 oil suitable for Nissan diesel engines?
No, NS-2 oil is designed specifically for gasoline engines. For diesel engines Nissan (YD, M9T series) oils with NS-1 specification or ACEA C3/C4 standards, which contain less ash, must be used.
What happens if you fill in oil with a viscosity of 5W-40?
The engine will start and run, but there may be problems with the operation of the phase shifters when cold, increased fuel consumption and deterioration in dynamics. The manufacturer does not recommend deviating from the specified viscosity of 5W-30.
Where is the best place to buy original oil?
It is recommended to buy oil from authorized dealers Nissan or in large specialized stores that work with direct deliveries. Avoid buying from markets or dubious online stores without reviews.
