NS1 Nissan oil: technical features, analogues and replacement tips

Motor oil NS1 is an original lubricating fluid developed by the company Nissan specifically for their engines. It meets the manufacturer's strict internal standards and is optimized to operate in a variety of climate conditions. However, there are many questions surrounding this oil: how does it differ from universal analogues, how to choose the right replacement, and what to look for when purchasing?

In this article we will look at unique chemical additives in NS1 that are not found in most universal oils, let's look at official approvals and those technical nuances that even dealers are silent about. You will also learn what mistakes when changing oil can reduce engine life by 30%, and how to avoid them.

What is NS1 oil and for which Nissan engines is it intended?

Oil NS1 is a synthetic motor oil with a viscosity 5W-30 or 0W-20 (depending on modification), developed by engineers Nissan together with the company Idemitsu Kosan. It is certified according to standards API SN And ILSAC GF-5, but has a number of unique additives adapted to the specifics of Japanese engines.

Officially recommended for the following models:

• 🚗 Nissan Qashqai (J10, J11) with motors HR16DE, MR20DD, M9R
• 🚙 Nissan X-Trail (T31, T32) with motors QR25DE, MR20DD
• 🚘 Nissan Juke (F15) with turbocharged MR16DDT and atmospheric HR16DE engines
• 🚛 Nissan Navara (D40) with diesel YD25DDTi (modification only 5W-30)

Oil Feature NS1 — increased resistance to oxidation at high temperatures (up to 150°C), which is critical for turbocharged engines. In addition, it contains molybdenum additives that reduce friction in pairs piston-cylinder by 12% compared to analogues.

⚠️ Attention: Oil NS1 0W-20 not suitable for diesel engines Nissan and engines with mileage of more than 150,000 km. In these cases, viscosity is required 5W-30 or specialized oils NS2/NS3.

Official NS1 oil specifications and approvals

The manufacturer declares the following standards for oil NS1:

Parameter	NS1 5W-30	NS1 0W-20
Viscosity grade (SAE)	5W-30	0W-20
API standard	SN	SN
ILSAC approval	GF-5	GF-5
Pour point, °C	-39	-45

Important: Oil NS1 tested on engines Nissan with variable valve timing control system (CVTC). It is compatible with catalytic converters and exhaust gas recirculation systems (EGR).

For models with hybrid powertrains (for example, Nissan Pathfinder Hybrid) oil with approval is required Nissan KLAM-009, which is also part of the line NS1, but has a modified additive package.

Top 5 analogues of NS1 oil: what can be filled instead of the original

Original oil NS1 is more expensive than many analogues, so owners often look for alternatives. Based on the results of laboratory tests and reviews from car owners, the best substitutes are:

1. Idemitsu Zepro Eco Medalist 0W-20 - actually the same product as NS1, but under a different brand. Contains identical molybdenum additives and is approved Nissan KLAM-009.
2. Mobil 1 ESP 5W-30 - suitable for diesel and gasoline engines Nissan with particulate filters. Superior NS1 by shear resistance (index HTHS 3.5 mPa s).
3. Castrol Edge Professional LL 5W-30 - recommended for turbocharged engines MR16DDT And MR20DD. Has improved cleaning properties.
4. Liqui Moly Top Tec 4200 5W-30 — optimal for engines with a mileage of more than 100,000 km due to the increased content of antioxidant additives.
5. Motul Specific Dexos2 5W-30 - universal option for Nissan And Renault with 共同平台. Complies with standard GM Dexos2, which guarantees compatibility with modern exhaust aftertreatment systems.

When choosing an analogue, be sure to check for approval Nissan KLAM-009 or KLAM-010 on the label. Without this, the risk of premature timing chain wear increases by 40%.

Why can't NS1 be mixed with other oils?

When mixing oils with different additive packages (for example, NS1 and semi-synthetics), a reaction occurs between molybdenum and calcium additives, which leads to the formation of sludge. This can clog the oil channels and cause the engine to starve of oil after just 5,000 km.

How to distinguish fake NS1 oil: 7 key signs

Counterfeit oils NS1 common in the market, especially in online stores. According to Nissan Russia, up to 25% of the “original” oil sold is counterfeit. Here's how to recognize it:

• 🔍 Packaging: The original canister has an embossed logo Nissan with microtext "Genuine Oil". Counterfeits are often smooth or with blurred embossing.
• 🏷️ Label: At the bottom of the original canister there is a QR code that leads to the website nissan-russia.ru. For fakes, the QR code is either missing or leads to third-party resources.
• 📦 Cover: On the original, the lid has push-pull protection (press and turn). Counterfeits are often equipped with a regular screw cap.
• 💧 Color and consistency: Original oil NS1 has a golden hue and does not become cloudy when shaken. Counterfeits are often darker and foamy.
• 📝 Documents: The original comes with a certificate of conformity with a hologram. Its absence is a sure sign of a fake.

The most reliable way to check is to buy from authorized dealers Nissan or in trusted stores such as Exist.ru or Autodoc. Original oil price NS1 5W-30 (4 l) starts from 3,200 rubles. If you are offered it for less than 2,500 rubles, it is 100% fake.

⚠️ Attention: Using counterfeit oil NS1 leads to accelerated wear of the turbine (2-3 times faster) and the formation of varnish deposits on the pistons. The first signs are increased oil consumption (more than 500 ml per 1,000 km) and knocking of hydraulic compensators.

NS1 oil change instructions: step-by-step algorithm

Changing the engine oil Nissan using NS1 has several nuances that are not indicated in standard manuals. Here are the detailed instructions:

Drain the old oil (be sure to use a warm engine!)

Replace the oil filter (article for Qashqai J11: 15208-9M00A)

Flush the engine with a special liquid (if another oil was used)

Fill in new oil to the “MAX” mark on the dipstick (volume for MR20DD - 4.4 l)

Check the level 5 minutes after filling -->

Process Features:

1. Warming up the engine: Before draining the oil, let the engine idle for 5-7 minutes. This will allow you to drain up to 95% of the waste (versus 70% with a cold drain).
2. Replacing the filter: On engines HR16DE And MR20DD The oil filter is located vertically. When removing it, use a special cup wrench (size 74 mm x 14 edges).
3. Flushing: If you are switching from another oil to NS1, be sure to use flushing fluid Liqui Moly Oil-Schlamm-Spulung (article 1998). It removes the remains of old additives.
4. Level control: After replacement, run the engine for 30 seconds, then check the level. It should be between the "MIN" and "MAX" marks. Overfilling more than 5 mm above "MAX" results in oil foaming.

For engines with a timing chain drive (e.g. MR20DD) it is recommended to reduce the replacement interval to 7,500 km if the car is operated in an urban cycle with frequent traffic jams. This is due to increased carbon deposits on the chain, which accelerates its stretching.

Common mistakes when using NS1 oil and their consequences

Even experienced car owners make mistakes that reduce engine life. Here are the most common:

• ⏳ Exceeding the replacement interval: Oil NS1 loses its properties after 10,000 km (or 1 year), even if the car has been little used. Ignoring this rule leads to jamming of the hydraulic compensators and wear of the camshafts.
• 🔄 Mixing with other oils: Topping up NS1 oils from another brand (even with the same specifications) cause an additive conflict. The consequence is the formation of an emulsion in the oil channels.
• 🌡️ Ignoring Viscosity: Use 0W-20 instead of 5W-30 in hot climates (for example, in the Krasnodar region) leads to a loss of oil pressure at temperatures above +35°C.
• 🔧 Incorrect filter tightening: An overtightened filter deforms the sealing ring, which leads to leaks. Standard tightening torque - 18 Nm.

One of the most dangerous mistakes is using oil NS1 0W-20 in engines with mileage of more than 200,000 km. Due to the increased gaps in the friction pairs, such oil does not provide sufficient protection, which leads to “oil starvation” and rotation of the liners.

Reviews from Nissan owners about NS1 oil: pros and cons

Analysis of reviews on forums (Drive2.ru, Nissan-Club.ru) shows that opinions about the oil NS1 are separated. Here are the key observations:

Pros:

• ✅ Reducing oil consumption due to waste (from 1 l/10,000 km to 300–400 ml/10,000 km).
• ✅ Quieter engine operation when cold (especially noticeable in HR16DE).
• ✅ Improved throttle response due to reduced friction.

Cons:

• ❌ High price (30–40% more expensive than analogues).
• ❌ Difficulties with purchasing in the regions (frequent fakes).
• ❌ Some owners note accelerated blackening of the oil (after 3,000 km), which is associated with active detergent additives.

Interesting fact: On the forum Nissan Juke Club conducted an independent test in which they compared NS1 And Idemitsu Zepro Eco Medalist. The results showed that the difference in engine protection is no more than 3%, but the price differs by almost 2 times. This makes you think about the advisability of buying the original.

FAQ: Answers to popular questions about NS1 oil

Can NS1 be used in engines of other brands (eg Renault or Mitsubishi)?

Theoretically, it is possible if the engine meets the standards API SN And ILSAC GF-5. However NS1 optimized for the system CVTC from Nissan, therefore in engines Renault (For example, K4M) it can cause faster aging of the seals. For Mitsubishi It is better to use oils with approval Mitsubishi Oil Standard.

How often should you change NS1 oil when driving on gas?

When operating on gas (LPG), oil change interval NS1 should be reduced by 30%. That is, instead of 10,000 km - 7,000 km. This is because the gas burns at a higher temperature, accelerating the oxidation of the oil. In addition, it is recommended to use the modification 5W-30, since it better retains viscosity under high loads.

Which is better: NS1 or NS2?

Oil NS2 (viscosity 5W-40) is intended for engines with a mileage of more than 150,000 km or operated in difficult conditions (towing, off-road). It has a high ash content (1.1% against 0.8% at NS1), which better protects worn parts, but can clog the particulate filter faster. For new engines NS1 preferable.

Is it possible to pour NS1 into a gearbox?

No, NS1 - This is exclusively motor oil. For gearboxes Nissan (for example, CVTs JF016E) requires special fluid Nissan CVT Fluid NS-2 or NS-3. Using engine oil in a gearbox will lead to failure of clutches and bearings after just 5,000 km.

Why did fuel consumption increase after replacing it with NS1?

This is a temporary phenomenon due to the fact that NS1 has a lower viscosity at cold start (HTHS 2.6 mPa s) than many semi-synthetic oils. During the first 200–300 km, the engine “gets used” to the new lubricant, which can increase fuel consumption by 0.3–0.5 l/100 km. After adaptation, the indicators will return to normal.
