Nissan 5W40 A3/B4 oil: how to choose the right one and not harm the engine

Choosing motor oil for cars Nissan - a task that requires attention to detail. Especially when it comes to specifications 5W40 A3/B4, which are often recommended for modern gasoline and diesel engines from the Japanese manufacturer. But why exactly this viscosity class and tolerances? ACEA A3/B4? The fact is that such oils optimally combine protection during cold starts (thanks to the index 5W) and stability at high temperatures (designation 40), which is critical for turbocharged and forced engines Nissan.

However, not everything is so simple: under the brand Nissan original oil for sale KE900-90142 (5W40 A3/B4), but there are dozens of analogues on the market from Mobil, Castrol, Liqui Moly and others. How not to make a mistake with your choice? In this article we will look at:

• 🔧 What do A3/B4 specifications mean? and why they are important for engines Nissan.
• 🚗 What Nissan models require 5W40 A3/B4 oil (spoiler: this is not only Qashqai And X-Trail).
• ⚠️ Common mistakes when purchasing oils that reduce engine life.
• 📊 Comparison of original oil and analogues by price, properties and reviews.

What are A3/B4 specifications and why are they critical for Nissan?

Tolerances ACEA A3/B4 is a European standard that defines the minimum requirements for motor oils for gasoline (A3) and diesel (B4) engines. For Nissan These specifications are relevant for several reasons:

Firstly, A3 guarantees high oil stability over long drain intervals and protection against wear under high load conditions - this is important for turbocharged engines, for example, MR20DDT (installed on Qashqai J11 And X-Trail T32). Secondly, B4 implies compatibility with diesel engines equipped with a direct injection system Common Rail, which are sensitive to the quality of the lubricant. That's why oil 5W40 A3/B4 often becomes a universal solution for crossovers and sedans Nissan, operated in Russia.

But there is a nuance: Nissan not always strictly tied to ACEA. In some manuals (for example, for Navara NP300) you can find a reference to the standard API SN/CF. This is not a contradiction, but an addition: API SN is responsible for compatibility with modern gasoline engines, and CF - for diesels. However A3/B4 covers both of these requirements, so oil with this marking is suitable for most models.

Which Nissan models require 5W40 A3/B4 oil: complete list

Manufacturer recommends oil 5W40 A3/B4 for a wide range of models, but most often it is mentioned in the service books of the following cars:

• 🚙 Nissan Qashqai (J10, J11) with motors MR20DE, MR20DDT, M9R (diesel).
• 🚙 Nissan X-Trail (T31, T32) - especially for versions with turbodiesel R9M.
• 🚙 Nissan Juke (F15) with motors HR16DE And MR16DDT.
• 🚙 Nissan Pathfinder (R51, R52) - for gasoline VQ35DE and diesel V9X.
• 🚙 Nissan Navara (NP300, D40) - wear protection under high loads is critical here.

Important: for hybrid models (e.g. Nissan Ariya) or electric cars (Leaf) oil 5W40 A3/B4 not applicable - they either have separate requirements for transmission fluids, or do not require lubrication at all.

If your model is not listed, check the section "Maintenance" in the service book or use the online catalog official website of Nissan Russia. For example, for Nissan Almera G15 (motor H4M) is often recommended 5W30, not 5W40 - This is a typical mistake of owners.

Why is 5W40 not suitable for Almera G15?

In the engine H4M (1.6 L) uses narrower oil passages and thicker oil 5W40 at low temperatures it can create excessive resistance, which will lead to oil starvation in the first seconds after startup. Nissan recommends 5W30 with permission ILSAC GF-5 for this model.

Original Nissan 5W40 A3/B4 oil: items and features

Official oil from Nissan supplied under article number KE900-90142 (5 l canister) and KE900-90140 (1 l). This is a synthetic oil produced by Eni (Italy) upon request Nissan. Its key features:

• 🛡️ Increased oxidation resistance - important for turbocharged engines, where the oil heats up to 120–140°C.
• 🔥 Low ash content (mid SAPS), which extends the life of particulate filters (DPF) in diesel engines.
• ❄️ Pour point -42°C, which is relevant for Russian winters.

However, the original oil has two disadvantages: firstly, price (from 3,500 rubles per 5 liters in 2026), secondly, fakes. According to NISSAN MOTOR RUS, up to 30% of canisters on the market are counterfeit. How to distinguish the original?

Sign	Original	Fake
Cover	Screws tightly and is tamper evident	Easy movement, often without a seal
Label	Glossy, with clear font and hologram	Matte, blurry letters, no hologram
Level sensor	Transparent plastic with clear scale	Cloudy plastic, scale erased
Smell	Neutral, without harsh impurities	Strong chemical or gasoline smell

⚠️ Attention: If the canister is not marked KE900-90142 or inscription "Nissan Motor Oil" with a brand logo is 100% fake. Also, original oil is never sold in 4 liter plastic bottles.

Top 5 analogues of Nissan 5W40 A3/B4 oil: what to choose instead of the original

If the original oil is not available or you are looking for a more budget option, consider proven analogues with approval A3/B4. We analyzed owner reviews Nissan on Drive2 And Auto.ru, as well as data from independent tests (for example, from ADAC) to make a rating:

1. Castrol Edge 5W40 A3/B4 (article 15669A) is the leader in viscosity stability at high temperatures. Suitable for Qashqai with motor MR20DDT.
2. Mobil 1 ESP 5W40 (article 152621) - low ash oil for diesel engines with DPF. Ideal for X-Trail with R9M.
3. Liqui Moly Top Tec 4200 5W40 (article 3701) - German quality, but more expensive than analogues. Recommended for Pathfinder with mileage >100 thousand km.
4. Motul X-Clean 5W40 (article number 104777) is a universal choice for gasoline and diesel engines. Popular among owners Navara.
5. Total Quartz INEO ECS 5W40 (article 183978) - a budget option with good cleaning properties. Suitable for Juke.

Important: even among analogues there are nuances. For example, Mobil 1 ESP 5W40 has a low ash content (Low SAPS), which is good for diesel engines with a particulate filter, but may be excessive for simple gasoline engines. A Liqui Moly Top Tec 4200 contains a reinforced package of anti-wear additives, which is important for used engines.

🔹 Compliance with A3/B4 tolerance (indicated on the label)

🔹 Availability of API SN/CF or ILSAC GF-5 certificates

🔹 No cloudiness or sediment in the canister

🔹 Production date (oil older than 2 years loses its properties)-->

Oil change intervals 5W40 A3/B4: when to change ahead of schedule

Official regulations Nissan for oil 5W40 A3/B4 — every 15,000 km or once a year. However, these figures are relevant for “ideal” conditions: European roads, high-quality fuel, moderate climate. In Russia, real intervals are reduced:

• 🏙️ Urban cycle (constant traffic jams, short trips) - 10,000 km.
• ❄️ Operation at -30°C and below — 12,000 km (oil loses fluidity faster).
• 🛣️ Frequent off-road trips (For example, Navara in rural areas) - 10,000–12,000 km.
• ⛽ Using low quality fuel — 8,000–10,000 km (oil additives work faster to neutralize sulfur).

Critical error: ignoring the condition of the oil based on external signs. If a thick black liquid with metal particles is visible on the dipstick, a replacement must be made immediately, even if the mileage has not reached the specified value.

How to check the condition of the oil without laboratory analysis?

• 🔍 Color: fresh oil is amber, after 5,000 km it darkens, but remains transparent. If it is black and opaque, the additives have worked.
• 👃 Smell: a burnt smell indicates overheating, a sour smell indicates antifreeze.
• 🧲 Magnetic test: drop oil on the magnet - if a lot of metal shavings stick, the motor will wear out faster.

Typical mistakes when choosing and replacing 5W40 A3/B4 oil

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

1. Ignoring Tolerances. For example, buying oil 5W40 API SN without A3/B4. Consequences: accelerated wear of the turbine (if there is one) and the formation of deposits on the piston rings.
2. Mixing oils of different brands. Even if both oils 5W40 A3/B4, additives may react. Exception: topping up up to 10% original oil in case of leakage.
3. Neglecting to replace the oil filter. Filter Nissan (article 15208-65F0E) is designed for 15,000 km, but if it is not changed, it becomes clogged and the bypass valve opens - the oil bypasses the filtration.
4. Overfilling or underfilling oil. The optimal level is between the marks MIN And MAX on the dipstick. Overfilling by 0.5 liters increases the pressure in the system and the risk of squeezing out the seals.

⚠️ Attention: If after changing the oil to 5W40 A3/B4 There is a knocking sound from the hydraulic compensators, this is not always an oil defect. More often the reason is contaminated oil channels - the engine needs to be flushed with a special liquid (for example, Liqui Moly Pro-Line).

Another mistake is to believe myths. For example, that “synthetics 5W40 suitable for all engines Nissan" Actually for Almera N16 (motor QG18DE) manufacturer recommends 10W40, and for GT-R - special oil Nismo with viscosity 10W60.

FAQ: Frequently asked questions about Nissan 5W40 A3/B4 oil

Is it possible to use 5W40 A3/B4 oil in a Nissan with a mileage of more than 200 thousand km?

Yes, but with reservations. For engines with high mileage, it is better to choose oil with increased viscosity at operating temperature (For example, Liqui Moly Hochleistungs 5W40), since the gaps in the friction pairs increase. It is also recommended to reduce the replacement interval to 8,000–10,000 km and use a flush before replacement.

What is the difference between Nissan 5W40 A3/B4 and Nissan 5W30?

The main difference is viscosity at high temperatures. Oil 5W40 thicker at +100°C, which is better for turbocharged and diesel engines, and 5W30 thinner and more fuel efficient, but less protective under extreme loads. For most models Nissan (except Almera G15 And Note) is preferable 5W40 A3/B4.

Is it possible to fill 5W40 A3/B4 oil into a Nissan gearbox?

No! 5W40 A3/B4 - This is motor oil. For manual transmission and automatic transmission Nissan special transmission fluids are used: Matic Fluid D (article KE908-99932) for CVTs, MT-XZ (article KE916-99931) for mechanical boxes. Mixing oils leads to failure of clutches and bearings.

Which oil filter is suitable for 5W40 A3/B4 oil?

For most models Nissan (Qashqai, X-Trail, Juke) original filter fits 15208-65F0E. For Navara NP300 — 15208-ED00A. Among the analogues we recommend:

• 🔧 Mann W712/94 — high quality filter element.
• 🔧 Framm PH7317 - a budget option with good reviews.
• 🔧 Mahle OC507D — optimal for diesel engines.

What to do if the Check Engine light comes on after changing the oil?

The reasons may be different:

1. Poor quality oil - counterfeit or non-compliance with specifications. Solution: drain and replace with a proven brand.
2. Not adding enough oil - level below MIN. Solution: top up to normal.
3. Dirty oil filter - if the filter was installed without replacement. Solution: replace the filter.
4. Oil pressure sensor failure. Solution: check the error with a scanner (for example, ELM327) and reset it.

If Check Engine flashes - stop the engine immediately and call a tow truck! This may indicate oil starvation.
