Choosing the right engine oil for a Japanese brand car is a critically important task that directly affects the life of the power unit. In the line of lubricants Nissan a special place is occupied by a product with viscosity 5W-40, which has become a kind of βgold standardβ for most of the companyβs gasoline and diesel engines. This universal viscosity allows the engine to start confidently in winter at temperatures down to -30Β°C, while maintaining the necessary protective film in the heat.
Many owners Qashqai, X-Trail and Teana wondering why this particular parameter is recommended by the manufacturer. The secret lies in the balance between fluidity at cold start and stability of kinematic viscosity at operating temperatures. Usage Nissan 5W-40 ensures optimal operation of hydraulic compensators, reduces wear on the piston group and maintains the cleanliness of the internal channels of the lubrication system.
Technical characteristics and physical and chemical properties
Engine oil with index 5W-40 belongs to the category of all-season synthetic or semi-synthetic fluids. The first number β5β indicates low-temperature viscosity, which guarantees pumpability of the oil at subzero temperatures. The second number β40β characterizes high-temperature viscosity, which determines the ability of the oil to maintain protective properties when the engine heats up to 100Β°C and above.
Original oil Nissan is developed taking into account the specific operation of Japanese engines, which often have narrow oil channels and high speeds. The key parameter here is viscosity index, which for a quality 5W-40 product usually exceeds 160 units. This means that when heated, the oil does not become too liquid, and when cooled, it does not thicken to the state of paraffin.
The product contains additive packages responsible for detergent, dispersant and antioxidant properties. They prevent the formation of sludge and carbon deposits on valves and pistons. Particular attention is paid to corrosion protection, as modern engines Nissan often work under conditions of short trips, when condensate does not have time to evaporate from the crankcase.
Compatible with various engine models
Viscosity 5W-40 is the most universal for a wide range of models Nissan. It is ideal for naturally aspirated engines of 1.6, 1.8, 2.0 and 2.5 liters, as well as turbocharged versions. However, you should carefully choose if your car is equipped with specific systems, for example, CVTCS variable valve timing system or direct fuel injection.
For diesel engines such as YD or M9R series, installation 5W-40 is often a mandatory recommendation, especially in regions with harsh climates. Oil must meet standards ACEA C3 or API SN/CFto avoid damaging the diesel particulate filter (DPF) and catalyst. The wrong choice of additives can lead to rapid clogging of the exhaust system filter elements.
Among the models where use Nissan 5W-40 confirmed by factory instructions, we can highlight:
- β Nissan Qashqai with HR16DE and MR20DE engines
- β Nissan X-Trail all generations, including hybrid versions
- β Nissan Teana with motors VQ25DE and VQ35DE
- β Nissan Pathfinder and Patrol (for diesel versions)
- β Nissan Note and Almera (petrol versions)
Original oil vs analogues
The question of choosing between the original product Nissan Motor Oil and high-quality analogues from global manufacturers (Motul, Shell, Mobil) remains debatable. The original oil is produced at partner factories (often Idemitsu or Shell) and undergoes strict certification for specific requirements Nissan. This ensures compatibility with seals and gasket materials.
Analogues may offer a wider selection of base oils and additive packages, but they risk not passing the specific tests that engineers conducted Nissan. For example, some third-party oils may have aggressive detergent properties, which over time will lead to seal leakage on older engines with mileage of more than 150,000 km.
If you decide to use an analogue, make sure it meets the specifications API SN or ACEA A3/B4. It is also important to check the availability of manufacturerβs approvals indicated on the canister. Ignoring these requirements may void your engine warranty at the dealership.
β οΈ Attention: Buying original oil Nissan in markets or in unverified stores carries a high risk of purchasing a counterfeit. The counterfeit often has the wrong density and does not contain the necessary additives, which can lead to a major overhaul of the engine after only 5-10 thousand kilometers.

Replacement procedure and service intervals
Timely oil changes are the key to a long engine life. For most models Nissan with an engine running on 5W-40, the recommended interval is 10,000 β 15,000 km or once a year, whichever comes first. However, in city conditions with frequent traffic jams and cold starts, this interval should be reduced to 7,000 - 8,000 km.
Before starting work, you need to prepare the following tools: a new oil filter, a drain plug with a gasket (or sealant), a funnel and a waste container. The engine must be warmed up to operating temperature so that the oil drains faster and carries more suspended particles with it.
The replacement sequence is as follows:
- π οΈ Raise the car on a lift or overpass, ensure secure fixation.
- π οΈ Unscrew the drain plug and drain the old oil into the prepared container.
- π οΈ Replace the oil filter by first lubricating the rubber sealing ring with new oil.
- π οΈ Screw the plug with a new seal and fill in fresh oil Nissan 5W-40 through the neck.
- π οΈ Check the level with a dipstick and run the engine for a couple of minutes to check for leaks.
βοΈ Preparing for an oil change
Features of oil change in diesel engines
In Nissan diesel engines, the oil volume may be 0.5-1.0 liters larger compared to gasoline counterparts. Be sure to use a filter with the correct bypass valve, as diesel engines have higher system pressure. When replacing, it is also recommended to check the condition of the timing belt, since access to it is often blocked by the oil pan.
Oil consumption and typical problems
Oil consumption rate for engines Nissan it is considered up to 300-500 ml per 1000 km, especially during the break-in period or during active driving. However, if you notice that the level 5W-40 falls much faster, this may indicate problems. Owners often encounter oil burns on HR16DE series engines due to stuck piston rings.
Another common cause of high consumption is worn valve seals or oil seals. In this case, oil enters the combustion chamber, leaving a black deposit on the spark plugs. Using thicker oil, e.g. 10W-40, may temporarily reduce consumption, but will not completely solve the problem and may complicate cold starts in winter.
It is also worth paying attention to the crankcase ventilation (PCV) system. If the valve diaphragm is destroyed, excess pressure forces oil through the seals and through the ventilation system into the intake manifold. Regularly checking the condition of this system will help avoid unnecessary expenses on oil.
| Engine model | System volume (l) | Recommended oil | Replacement interval |
|---|---|---|---|
| HR16DE (1.6 l) | 4.9 | Nissan 5W-40 SN | 10,000 km |
| MR20DE (2.0 l) | 4.8 | Nissan 5W-40 SN | 10,000 km |
| VQ25DE (2.5 l) | 5.0 | Nissan 5W-40 SN | 10,000 km |
| YD25DDTi (2.5 l diesel) | 6.5 | Nissan 5W-40 C3 | 10,000 km |
Always keep 1-2 liters of oil in the trunk Nissan 5W-40 for topping up. A sharp drop in oil level on the road can lead to oil starvation and seizures in the engine, especially in hot weather.
Storage and operating conditions
Even the best quality oil Nissan 5W-40 may lose its properties if stored improperly. Canisters should be kept in a dry, cool room, protected from direct sunlight. The storage temperature should not fall below -20Β°C, as this may lead to separation of the additives in the lubricant.
The shelf life of motor oil is usually 3-5 years from the date of manufacture. Always check the release date on the canister before purchasing. If the oil has been sitting on a store shelf for more than 3 years, it is better not to use it, as the additive package could begin to deteriorate, even if the plastic of the canister is intact.
When operating a vehicle in extreme conditions (dusty roads, extreme heat or constant city driving in traffic jams), it is recommended to shorten the replacement interval and use oils with improved thermal stability. In such modes 5W-40 works at the limit of its capabilities, and its protective properties are depleted faster.
β οΈ Attention: Never mix oils from different manufacturers or different specifications. Even if both products have viscosity 5W-40, their chemical composition of additives may be incompatible, which will lead to sedimentation and loss of lubricating properties.
Regular oil changes Nissan 5W-40 At regular intervals, this is the cheapest way to extend the life of your engine and avoid costly repairs in the future.
Frequently asked questions and answers
Can I use 5W-40 oil in a Nissan engine if 5W-30 is recommended?
Usage 5W-40 instead of 5W-30 acceptable, especially if the car has a high mileage (more than 100,000 km) or is operated in a hot climate. Thicker oil better compensates for gap wear, but may slightly increase fuel consumption. However, for new engines and hybrid systems, it is better to follow the manufacturer's recommendations.
How to distinguish original Nissan oil from a fake?
Original oil Nissan has clear markings, the font on the canister is not blurred, and the label is glued evenly. The lid usually has a protective ring that should break off when opened. You can also check the QR code or hologram if they are present on the package. Buy oil only from authorized dealers or large chain stores.
How much oil is needed for a complete change in Nissan Qashqai 1.6?
For HR16DE engine (1.6 l) in Nissan Qashqai Approximately 4.9 liters of oil are required when changing with a filter. It is recommended to buy a 4-liter canister and another 1-liter canister, since the exact volume may vary depending on the condition of the engine and the completeness of draining the old fluid.
Does fuel type affect the choice of 5W-40 oil?
Yes, the type of fuel makes a difference. For diesel engines it is necessary to use oil with low ash content (Low SAPS) to ACEA C3 or C4 specification to avoid clogging of the diesel particulate filter. Gasoline engines can use oil with a higher detergent content (ACEA A3/B4).
Is it possible to add another oil if there is no original one?
In an emergency, you can add oil from a different brand if it has the same viscosity (5W-40) and similar approvals (API SN/ACEA A3/B4). However, after arriving at the service center, it is necessary to completely change the oil and filter as soon as possible in order to avoid chemical reactions between different additive packages.
Selecting quality oil Nissan 5W-40 and following proper replacement procedures is an investment in the reliability of your vehicle for years to come.
