Nissan 5W40 A3/B4 engine oil: how to choose and not make a mistake

When it comes to choosing engine oil for Nissan, owners are often faced with a dilemma: what is better - original oil from the manufacturer or analogues with suitable specifications? This issue is especially relevant for oils with a viscosity 5W40 and tolerances A3/B4, which are recommended for most modern brand engines. But why exactly these parameters? And how not to make a mistake when buying so as not to harm the engine?

In this article we will analyze in detail what the designations mean 5W40 And A3/B4what models Nissan require such oil, and we will also analyze the best options from leading manufacturers - from Nissan Motor Oil to Mobil, Castrol And Liqui Moly. In addition, you will learn how to recognize a fake, what mistakes are most often made when replacing, and why saving on oil can result in expensive repairs.

What do the designations 5W40 and A3/B4 mean?

Marking 5W40 on a canister of oil indicates its viscosity-temperature properties. Digit 5 before the letter W (from English Winter - winter) denotes the minimum temperature at which the oil remains fluid. In this case it is -30°C (subtract 35 from the number in front of W). Second digit 40, shows the viscosity at engine operating temperature (100°C). This oil is suitable for most climatic zones of Russia, including regions with cold winters.

Tolerances A3/B4 are quality standards established Association of European Automotive Manufacturers (ACEA). They guarantee that the oil:

• 🔧 Suitable for gasoline and diesel engines (including turbocharged ones).
• 🛡️ Provides high protection against wear and deposits.
• 🔥 Works stably at high temperatures and loads.
• 🔄 Has an extended replacement interval (up to 20-30 thousand km depending on operating conditions).

It is important to understand that A3/B4 - this is not just “good oil”, but a specific set of requirements for its properties. For example, it must withstand higher loads than oils approved A1/B1, which are designed for economical engines with short replacement intervals.

Which Nissan models require 5W40 A3/B4 oil?

Manufacturer Nissan recommends oils with a viscosity 5W40 and tolerances A3/B4 for most modern models equipped with gasoline and diesel engines. This is especially true for cars with turbocharging or direct fuel injection, where the oil requirements are higher.

Here are the key models for which this oil is the best choice:

Model Nissan	Engine	Year of manufacture	Notes
Qashqai (J11)	HR16DE, MR20DD, R9M (diesel)	2014–present time	Diesel requires approval C3 or C4 in addition to A3/B4.
X-Trail (T32)	MR20DD, M9R (diesel)	2014–2022	For hybrid versions, an oil with approval is recommended SN via API.
Juke (F15)	HR16DE, MR16DDT (turbo)	2014–2019	For turbo engines, the replacement interval is reduced to 10–15 thousand km.
Navara (NP300)	YD25DDTi (diesel)	2015–present time	An oil with increased oxidation resistance is required.
Almera (N18)	HR16DE, K4M	2019–present time	Suitable oil with energy-saving properties (A5/B5 also acceptable).

For accurate oil selection, always check your car's manual. For example, for Nissan GT-R Approved oil required A3/B4, but with viscosity 10W60 due to extreme loads. But for Nissan Leaf (electric car) engine oil is not needed at all - it uses transmission fluid for the gearbox.

Original Nissan 5W40 oil vs analogues: which is better?

Manufacturer Nissan offers its own line of branded oils Nissan Motor Oil. For example, Nissan Strong Save X 5W40 - this is a synthetic oil with tolerances A3/B4, SN (API) and C3 (for diesel engines). Its advantages:

• ✅ Guaranteed compatibility with Nissan engines.
• ✅ Optimized additive package for wear protection.
• ✅ Passes strict quality control at Nissan factories.

However, original oil is not always available or may be more expensive than analogues. Among the alternatives are:

• 🔹 Mobil 1 ESP Formula 5W40 — suitable for gasoline and diesel engines, including turbocharged ones. Has approvals VW 502.00/505.00, which confirms the high quality.
• 🔹 Castrol Edge Professional A3/B4 5W40 - Recommended for sports and powerful engines. It is stable at high temperatures.
• 🔹 Liqui Moly Top Tec 4200 5W40 - universal oil with approvals MB 229.5 And BMW LL-04, fits most Nissan.
• 🔹 Motul 8100 X-cess 5W40 — synthetic oil with improved cleaning properties, ideal for urban use.

⚠️ Attention: If you choose an analogue, make sure that the tolerances are indicated on the canister A3/B4 And SN (or higher) via API. Oils with approval A1/B1 or ILSAC GF-5 are not suitable for most Nissan engines as they do not provide sufficient protection under high loads.

To check the authenticity of the oil, pay attention to:

• 📦 The quality of the canister (the original ones have straight seams, clear printing, holograms).
• 🔖 Availability of protective stickers or QR codes for verification on the manufacturer’s website.
• 💧 Oil consistency (counterfeits often have a strong odor or uneven color).

How often do you change 5W40 oil in Nissan?

Official recommendations Nissan state that the oil change interval is 15,000 km or 1 year (whichever comes first). However, this period is relevant only for ideal operating conditions:

• 🌡️ Moderate climate (without extreme frost or heat).
• 🛣️ Mostly country roads (no traffic jams).
• 🚗 Calm driving style (no sudden acceleration).

In reality, most cars are operated in more severe conditions, so the replacement interval should be reduced:

Operating conditions	Recommended replacement interval
City mode (traffic jams, short trips)	8,000–10,000 km
Aggressive driving (frequent acceleration, high revs)	7,000–9,000 km
Extreme temperatures (heat above +35°C or frost below -25°C)	7,000–10,000 km
Turbocharged engine	10,000–12,000 km

⚠️ Attention: If you use oil with approval A3/B4 in a diesel engine Nissan (For example, X-Trail with motor M9R), be sure to check the oil level every 2,000–3,000 km. Diesels are more prone to oil burns, especially when driving frequently over short distances.

How do you know when it's time to change the oil?

• 🔍 Darkening of the oil (a normal process, but if it becomes black and thick, replace it urgently).
• 💨 The appearance of a burning smell or metal shavings in the oil.
• 📉 Drop in oil level between changes (more than 1 liter per 10,000 km).
• 🔊 Increased engine noise (knocking of hydraulic compensators, increased vibration).

Drain the old oil on a warm engine (temperature ~60°C)|Replace the oil filter (original or high-quality analogue)|Rinse the engine if the oil is heavily contaminated|Check the level of new oil 5-10 minutes after filling|Reset the maintenance counter (if any)-->

Step-by-step instructions for changing the oil in Nissan

Changing the oil in Nissan - a procedure that can be performed independently if you have a minimum set of tools and an inspection hole (or lift). Let's look at the process using an example Nissan Qashqai J11 with engine HR16DE:

Required materials and tools:

• 🛢️ 4–5 liters of oil 5W40 A3/B4 (see the manual for the exact volume).
• 🔧 Oil filter (original number: 15208-9M50A for Qashqai).
• 🔩 14 mm wrench for drain plug.
• 🔧 Oil filter puller (if it is too tight).
• 🧻 Rags, gloves, container for draining waste (minimum 5 l).

Step by step process:

1. Warm up the engine to operating temperature (about 60°C) so that the oil becomes less viscous and drains better. Don't overheat — hot oil can burn!

2. Raise the car on a lift or drive it into a viewing hole. Make sure the car is level.

3. Unscrew the drain plug (it is located on the oil pan) and drain the oil into a prepared container. Let the oil drain completely (10–15 minutes).

4. Replace the oil filter. Before installing a new filter, lubricate the rubber O-ring with fresh oil. Tighten the filter by hand, without using tools!

5. Install a new sealing washer on the drain plug (copper or aluminum, included with the filter or purchased separately). Tighten the plug to a torque of 30–40 Nm.

6. Fill in new oil through the oil filler neck. For HR16DE about 4.3 liters will be required. Check the level using the dipstick.

7. Start the engine and let it idle for 1-2 minutes. Check for oil leaks from under the filter or plug.

8. Stop the engine, wait 5-10 minutes and check the oil level again. Top up if necessary.

If you are changing the oil for the first time, pay attention to the color and consistency of the drained oil. For example, if metal particles are visible in the oil, this may indicate increased engine wear. In this case, it is worth contacting for diagnostics.

What should I do if the pressure light comes on after changing the oil?

If, after changing the oil, the pressure lamp on the instrument panel comes on and does not go out 2-3 seconds after starting the engine, the following reasons are possible:

1. **Low oil level** - check with dipstick and add if necessary.

2. **Faulty oil filter** - it may be installed incorrectly or defective. Try replacing it.

3. **Clogged oil channels** - if the oil has not been changed for a long time, carbon deposits could form. In this case, engine flushing is required.

4. **Faulty oil pressure sensor** - check its functionality with a multimeter.

If the lamp flashes or stays on, do not operate the car - this can lead to serious engine damage.

Top 5 mistakes when choosing and changing oil in Nissan

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

1. Ignoring manufacturer's approvals. For example, filling oil 5W30 A1/B1 instead of 5W40 A3/B4. This oil cannot withstand high loads, which leads to accelerated wear of the turbine or piston rings.

2. Saving on oil filter. Cheap filters may not retain dirt particles, which leads to clogged oil passages. Original filters Nissan or high-quality analogues (for example, Mann, Bosch) are inexpensive, but extend the life of the engine.

3. Incomplete drainage of old oil. If you do not allow the oil to drain completely or do not flush the engine when switching to another type of oil, waste residues will mix with the new oil, worsening its properties.

4. Exceeding the replacement interval. Even if you drive little, oil ages over time. For example, if you only drove 5,000 km in a year, the oil still needs to be changed.

5. Unnecessary use of flushing fluids. Aggressive flushing can damage seals and oil seals, especially in older engines. If the oil has been changed regularly, flushing is not necessary.

⚠️ Attention: If you decide to switch from one type of oil to another (for example, from 5W30 on 5W40), be sure to flush the engine special oil for flushing (not five-minute liquid!). This will help avoid additive conflicts.

Reviews from Nissan owners about 5W40 A3/B4 oil

To form an objective opinion, we analyzed reviews from owners Nissan Qashqai, X-Trail And Jukewho use oil 5W40 A3/B4. Here's what they note:

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

Is it possible to mix 5W40 A3/B4 oil with another oil?

Mix oils of different manufacturers or viscosities not recommended, as this may lead to additive conflicts and loss of properties. In emergency cases (for example, if you need to add oil on the road), you can mix 5W40 A3/B4 with oil of the same manufacturer with similar tolerances. After this, be sure to perform a complete oil and filter change.

Is 5W40 A3/B4 oil suitable for Nissan with mileage over 200,000 km?

For engines with high mileage, it is better to use oil with a higher viscosity (for example, 5W50 or 10W40), as the gaps between the parts increase. However, if the engine is in good condition and does not consume oil, 5W40 A3/B4 you can continue to use. The main thing is to reduce the replacement interval to 7,000–10,000 km.

What is the difference between A3/B4 oil and A5/B5 oil?

The main difference is in energy-saving properties. Oils A5/B5 have a lower high temperature viscosity (e.g. 5W30), which reduces friction and improves fuel efficiency. However they don't fit for engines where required A3/B4, as they do not provide sufficient protection under high loads. For most Nissan with turbocharging or diesel engines A3/B4 preferable.

Is it necessary to flush the engine when switching to 5W40 A3/B4 oil?

If you are switching from the same type of oil (eg. 5W30 A3/B4 on 5W40 A3/B4), washing is not necessary. It is enough to reduce the first replacement interval to 5,000–7,000 km. If the previous oil was of poor quality or of unknown origin, it is better to flush special flushing oil (not “five minutes”!).

Which oil is better for Nissan GT-R: 5W40 A3/B4 or 10W60?

For Nissan GT-R The manufacturer recommends an oil with a viscosity 10W60 and admission A3/B4, since the engine VR38DETT works in extreme conditions. Oil 5W40 does not provide sufficient protection at high temperatures and loads typical for this vehicle. Usage 5W40 can lead to overheating and accelerated wear of turbines.
