Nissan NS-2 oil: technical features, analogues and selection rules

Original motor oil Nissan NS-2 is a product designed specifically for modern alliance engines Renault-Nissan-Mitsubishi. It meets the strict requirements of the manufacturer and provides optimal protection of powertrain parts under high load conditions. However, there is a lot of controversy surrounding this oil: some owners praise it for its stability and efficiency, others are looking for analogues, considering the price too high.

In this article we will analyze in detail oil composition and specifications NS-2, compare it with popular analogues (including Mobil 1 ESP 5W-30 And Liqui Moly Special Tec AA 5W-30), and also give practical recommendations for replacement. We will pay special attention to the issue of compatibility with turbocharged engines and hybrid systems - this is critical for owners Nissan Qashqai J11, X-Trail T32 And Ariya.

Technical characteristics of Nissan NS-2 oil

Oil Nissan NS-2 belongs to the category semi-synthetic oils with viscosity 5W-30 and meets standards API SN And ACEA C2. Its key feature is its low sulfur, phosphorus and sulfate ash content (Low SAPS), making it compatible with exhaust aftertreatment systems (including particulate filters DPF and catalysts TWC).

The manufacturer declares the following parameters:

• 🔹 Viscosity at 100°C: 10.5–11.5 mm²/s
• 🔹 Viscosity index: 165–175
• 🔹 Pour point: –42°C
• 🔹 Base Number (TBN): 8.0–9.5 mg KOH/g

Important: oil NS-2 certified for use in engines with Start-Stop and turbocharging, but is not suitable for engines with mileage over 200 thousand km due to reduced high-temperature viscosity (HTHS ≤ 2.9 mPa s).

Compatible with Nissan and Renault models

Manufacturer recommends NS-2 for most petrol and diesel engines Nissan And Renault, released after 2010. However, there are nuances:

⚠️ Attention: For engines Nissan VR38DETT (for example, in GT-R R35) and VQ37VHR (370Z) oil NS-2 doesn't fit - requires specialized oil with viscosity 10W-60 and admission Nissan KE900-99932.

Advantages and disadvantages of NS-2 oil

According to reviews from owners and independent tests, Nissan NS-2 there are both strengths and weaknesses. Let's look at them in detail.

Pros:

• ✅ Economical: reduces fuel consumption by 2–3% due to low viscosity.
• ✅ Environmental Compatibility: doesn't score DPF and catalysts.
• ✅ Stability at low temperatures: Confident starting down to –30°C.
• ✅ Manufacturer Approved: maintains the warranty on the new car.

Cons:

• ❌ Price: 1.5–2 times more expensive than analogues (from RUB 3,500 per 5 l).
• ❌ Rapid aging: with a mileage of >15 thousand km, it loses its cleaning properties.
• ❌ Not suitable for hot climates: at +40°C a pressure drop is possible.

The best analogues of Nissan NS-2 oil

If the original oil is not available or its price seems too high, you can consider certified analogues. The main thing is that they comply with the tolerance Nissan KE900-99931 (for gasoline engines) or KE900-99930 (for diesel engines).

Top 5 proven analogues:

1. Mobil 1 ESP 5W-30 - the best choice for turbocharged engines, superior NS-2 on thermo-oxidative stability.
2. Liqui Moly Special Tec AA 5W-30 - ideal for Qashqai And X-Trail with the system Start-Stop.
3. Castrol Edge Professional A5 5W-30 - recommended for Renault with engines Energy TCe.
4. Total Quartz INEO ECS 5W-30 - a budget option with good cleaning properties.
5. Motul Specific DEXOS2 5W-30 - suitable for hybrids (eg Nissan Note e-Power).

⚠️ Attention: When switching from NS-2 to analog necessarily flush the system with oil of the same brand (for example, Liqui Moly Oil-Schlamm-Spulung). Mixing oils with different base stocks can cause sludge!

☑️ Checking the oil before changing

Make sure the engine is warmed up to 60–80°CUse the original filter (eg 15208-9M50A for Qashqai)Check the oil level 5 minutes after fillingReset the service interval in the on-board computer (Menu → Settings → Maintenance)

Instructions for changing NS-2 oil

Changing the engine oil Nissan using NS-2 does not require special skills, but there are several critical points. Let's look at the process using an example Nissan Qashqai J11 with engine HR12DDT.

Required tools and materials:

• 🔧 New oil Nissan NS-2 (4.5 l for HR12DDT, 5.4 l for MR20DD).
• 🔧 Oil filter (original - 15208-9M50A or equivalent Mann W712/94).
• 🔧 Filter puller (for example, 64 mm for Qashqai).
• 🔧 Key on 14 mm for the drain plug.
• 🔧 Flushing oil (optional if switching from another brand).

Step by step process:

1. Warm up the engine to operating temperature (60–80°C) so that the oil becomes less viscous.
2. Raise the car on a lift or use a jack (install jack stands!).
3. Drain the old oil through the plug in the pan (draining time - at least 15 minutes).
4. Replace the oil filter. Before installing the new filter, lubricate the rubber seal with fresh oil.
5. Screw the drain plug with a new sealing ring (tightening torque - 35–40 Nm).
6. Fill in new oil through the neck, checking the level with the dipstick. The optimal level is between the marks MIN And MAX.
7. Run the engine for 1–2 minutes, then check the level and absence of leaks.

What happens if you overfill the oil?

Exceeding the oil level by more than 5 mm above the mark MAX leads to increased pressure in the system, which can damage the crankshaft and camshaft seals. In turbocharged engines (HR12DDT, MR16DDT) this is also fraught with oil getting into the intercooler and subsequent smoking.

Common mistakes when using NS-2 oil

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

1. Ignoring replacement intervals

The manufacturer recommends replacement every 15,000 km or once a year, but in urban conditions (frequent traffic jams, short trips) the interval should be reduced to 10,000 km. Oil NS-2 quickly loses alkaline additives with frequent engine starts.

2. Mixing with other oils

Adding another brand of oil (for example, Shell Helix Ultra) may lead to precipitation. If you had to add another oil, necessarily Flush the system the next time you replace it.

3. Using non-original filters

Cheap filters (for example, without a check valve) can lead to oil starvation at startup. Original filters Nissan They have a reinforced housing and an increased area of the filter element.

4. Neglecting to check the level

Engines Nissan with timing chain drive (HR16DE, MR20DD) are sensitive to oil starvation. Check the level every 1,000 km!

💡

If after changing the oil to NS-2 The engine has become noisier, check the level - perhaps the oil has not had time to drain into the sump. Stop the engine for 10 minutes and repeat the test.

Owner reviews: real experience of use

To form an objective opinion about the oil Nissan NS-2, we analyzed reviews from owners on forums (including Drive2, Nissan-Club.ru And Renault-Drive>). Here are the key takeaways:

💡

Most negative reviews are related to non-compliance with replacement intervals or the use of oil in inappropriate conditions (high loads, extreme temperatures).

FAQ: Frequently asked questions about Nissan NS-2 oil

Is it possible to use NS-2 in an engine with a mileage of 180 thousand km?

No. For engines with a mileage of over 150 thousand km, an oil with a viscosity of 5W-40 and increased base number (for example, Liqui Moly Leichtlauf High Tech 5W-40). NS-2 has low high temperature viscosity (HTHS 2.9), which can lead to accelerated bearing wear.

Is NS-2 suitable for Nissan Almera G15 (K4M)?

Yes, but only for 2013 and newer models. For Almera Classic (until 2012) with engine QG16DE better to use oil 5W-40 with permission API SL.

Can NS-2 be mixed with Mobil 1 ESP 5W-30?

In emergency cases - yes, but not more than 1 liter. Both oils have a similar base (Low SAPS), but different additive packages. Perform a complete replacement with flushing as soon as possible.

Which oil filter is best for NS-2?

Optimal options:

• Original: 15208-9M50A (for Qashqai, X-Trail).
• Analogues: Mann W712/94, Bosch 0 451 103 336, Framm PH7318.

Avoid filters without a check valve - they can cause oil starvation at startup.

What should I do if the Check Engine light comes on after replacing the NS-2?

Probable reasons:

1. Incorrect oil level (check dipstick).
2. Poor quality filter (replace with original).
3. Oil getting into the crankcase ventilation system (valve diagnostics required PCV).

If the error does not clear, read the fault code (for example, via ELM327).
