This is especially true for models Nissan Qashqai with a turbocharged unit, where the exhaust gas temperature is much higher.
There is a myth that oil 5W40 too thick for new engines, but practice shows the opposite. It creates a durable oil film that prevents dry starts and wear of CPG parts. However, if your car has high mileage and high oil consumption, it may be worth considering more viscous options or checking the technical condition of the engine.
Real experience of owners: pros and cons of use
Analysis of forums and owner reviews Nissan Teana and X-Trail allows us to highlight a number of obvious advantages. Users often praise the stability of the oil pressure in the system even when the engine overheats in traffic jams. This indicates that viscosity 5W40 Doesn't sag too much under load. In addition, many note the quietness of the engine after replacing it with the original product.
However, there are also negative reviews associated with the period between replacements. Some car owners complain that by 7-8 thousand kilometers the oil begins to lose its properties faster than expected. This may be due to both operating conditions (frequent short trips, traffic jams) and the quality of the product itself in a particular batch. It is important to monitor the oil level and condition visually.
- ✅ Stable oil pressure in the system under high loads
- ✅ Good cleaning properties for turbocharged engines
- ❌ Rapid loss of protective properties under extreme conditions
- ❌ High cost of the original canister compared to analogues
Interestingly, engine owners VQ25 and VQ35 It is often noted that oil Nissan 5W40 better suited for their powertrains than the thinner 5W30.

|---|---|---|---|---|
| Nissan Genuine Oil | 5W-40 | Synthetics | API SN, ACEA A3/B4 | High |
| Shell Helix Ultra | 5W-40 | Fully synthetic | API SN, ACEA A3/B4 | Average |
| Mobil 1 FS | 5W-40 | Fully synthetic | API SN, ACEA A3/B4 | High |
| Idemitsu Zepro | 5W-40 | Synthetics | API SN, ILSAC GF-5 | Average |
⚠️ Attention: When purchasing oil from third-party sites, always check the integrity of the packaging and the presence of holograms. A counterfeit can lead to a major overhaul of the engine due to the lack of necessary additives.
What do experts say about Nissan 5W40 oil base?
Many experts believe that the original Nissan oil is produced at Idemitsu or Shell factories, but has its own unique additive package that distinguishes it from the standard products of these brands. This explains why oil can work better on Nissan engines than on analogues of other brands.
Features of operation in different climatic zones
Climate plays a decisive role in the choice of engine oil. For regions with harsh winters, where temperatures drop below -25°C, oil Nissan 5W40 demonstrates excellent results, providing easy starting. However, in extreme heat, when the engine is running under constant load, the thickness of the oil helps maintain compression and pressure in the system.
Car owners in the southern regions often note that oil does not require frequent topping up in the summer. This is due to the fact that viscosity 5W40 has a high viscosity index, which allows the oil not to become too liquid when heated. At the same time, for northern regions it is important to ensure that the oil does not thicken too much during critical frosts.
There is an opinion that for urban conditions with frequent traffic jams it is better to use oil with a lower viscosity, but this is not always true for engines VQ and MR. These engines are prone to overheating in traffic jams, and thicker oil 5W40 helps to better remove heat from the piston rings and cylinder walls. Therefore, the choice should depend on the specific model and driving style.
☑️ Checking the condition of the oil before changing
Technical nuances of replacement and service intervals
Proper oil changes are the key to long engine life. For cars Nissan It is recommended to use the original filter and drain plug gasket.
