Crossover operation Nissan Murano requires special attention to the power unit, especially when it comes to choosing lubricants. Many owners are faced with a dilemma: follow strictly factory recommendations or trust the experience of service centers using alternative brands. Incorrect choice of lubricant can lead to accelerated wear hydraulic compensators and loss of power.
Owners Nissan Murano different generations (Z50, Z51, Z52) often wonder about acceptable viscosities. The VQ series engines installed on these models have high speeds and specific requirements for oil fluidity. Using the wrong fluid may interfere with the operation of the variable valve timing system. VVT.
Factory recommendations and manufacturer specifications
Manufacturing plant Nissan clearly regulates the parameters of oils suitable for VQ35DE and VQ35HR engines. The main criterion is compliance with the specification ILSAC GF-5 or newer GF-6. API SN or SP approval is also required. These standards guarantee protection against carbon deposits and deposits in high temperature areas.
For most regions of Russia and CIS countries, the optimal viscosity is 5W-30. This indicator ensures easy starting in winter and reliable film at operating temperatures. In very hot climates, some owners switch to 5W-40, however, this may reduce the cooling efficiency of the piston group.
- ✅ 5W-30 — the optimal choice for year-round use in temperate climates.
- 🔧 0W-20 — allowed for new engines (with low mileage) in order to save fuel.
- ⚠️ 10W-40 — suitable only for engines with high mileage (more than 200 thousand km).
⚠️ Attention: Using oils with a viscosity higher than 40 (for example, 15W-50) without good reason can lead to engine overheating and failure of the variable valve timing system.
Please note that on modern models Nissan Murano (Z52) with VR30DDTT (turbo) engines the requirements are stricter. This is where it is critical to use low ash oils to avoid clogging complex exhaust cleaning systems.

Original oil versus analogues: what to choose?
Original oil Nissan Motor Oil often positioned as the best choice, but its quality varies depending on the region of supply and the manufacturing plant. Many car owners note that the original fluid quickly loses its properties during aggressive driving. At the same time, analogues from world brands often surpass standard products in terms of cleaning properties.
When choosing an analogue, you need to look not only at the brand, but also at the specific product line. For example, synthetic oils Full Synthetic provide better protection under high loads. It is important to check the presence of certificates of conformity on the packaging, since the market is oversaturated with counterfeits.
- 🏆 Liqui Moly — German quality, excellent detergent additives, popular among owners of VQ engines.
- 💎 Motul — ester oils provide maximum protection at extreme temperatures.
- ⚙️ Castrol — good fluidity and stability during long-term operation.
Always check the batch code and hologram on the canister. Genuine Nissan oil often has a unique marking, which can be checked on the manufacturer's website in your area.
You shouldn’t chase the “most expensive” oil if your crossover’s engine is in excellent condition. The main thing is compliance with tolerances. Overpaying for a brand does not always guarantee a better result compared to a high-quality analogue in the mid-price segment.
Production technologies: mineral water, semi-synthetic or synthetic?
For engines Nissan Murano It is strictly not recommended to use mineral oils. Modern VQ series motors have very tight gaps and complex lubrication system channels. The mineral base oxidizes too quickly and forms sludge that clogs the oil receiver mesh.
Semi-synthetics can be considered as a temporary solution for used engines, but synthetics remain the uncontested leader. Hydrocracking and PAO-synthetics provide stable viscosity and corrosion protection. It is synthetic oils that allow you to extend replacement intervals without risking the health of the engine.
Particular attention should be paid to the additive package. High-quality oil must contain dispersants that prevent combustion products from settling on the cylinder walls. This is critical for turbocharged versions Murano, where the temperature in the turbine reaches extreme values.
| Oil type | Temperature range | Recommendation for Murano |
|---|---|---|
| Mineral | -10°C to +30°C | Not recommended |
| Semi-synthetics | -25°C to +40°C | Acceptable for older engines |
| Synthetic 5W-30 | -35°C to +45°C | Optimal choice |
| Synthetic 0W-20 | -40°C to +35°C | For new engines and savings |
The correct procedure for changing the oil yourself
Changing the oil in Nissan Murano - a procedure that can be performed independently, having a basic set of tools. The process requires access to the underbody of the car and removal of the crankcase protection.
Before starting work, prepare a drainage container with a volume of at least 5 liters. Unscrew the drain plug, being careful as the oil may be very hot. Replace after complete drainage. oil filter - this is a prerequisite for extending the life of the motor.
☑️ Preparing for an oil change
Install the new filter after lubricating the rubber o-ring with fresh oil. Tighten the drain plug with the tightening torque specified in the instructions (usually about 40 Nm). Fill in new oil through the filler neck, checking the level with the dipstick.
How to check the oil level on a hot engine?|On VQ35 engines, the oil level is checked on a cold engine or after it has cooled down. If you check it while it’s hot, the readings will be inaccurate due to the expansion of the oil and its presence in the hydraulics of the phase regulators.-->
After filling, start the engine and let it run for 2-3 minutes. Check for leaks under the car. Then turn off the engine, wait 5 minutes and check the level again. It should be between the marks Min and Max.
Frequent mistakes made by owners during maintenance
One of the most common mistakes is ignoring the condition of the oil filter. Cheap filters without a backflow valve can cause a “dry” engine start, which is detrimental to camshafts. Always use original filters or proven analogues (for example, Blue Print or Meyle).
Another mistake is mixing different brands of oils. Even if they have the same viscosity, the additive packages may not be compatible. This leads to sedimentation and loss of lubricating properties. If you change brand, it is advisable to flush the system with special flushing oil.
- ❌ Pour oil “by eye” without checking with a dipstick.
- ❌ Use solvent-based washes before each replacement.
- ❌ Ignore the color and smell of old oil (black oil is the norm, but the smell of burning is a bad sign).
⚠️ Attention
Min and Max.If you notice metal shavings in the old oil or on the drain plug magnet, this is a sign of serious wear on the engine's internal components. Diagnosis required.
Replacement intervals and quality control
Factory regulations for Nissan Murano prescribes oil changes every 15,000 km or once a year. However, in real operating conditions (urban mode, traffic jams, short trips), the interval should be reduced to 7,000 - 8,000 km. This is due to the fact that in traffic jams the engine idles, but the oil heats up and oxidizes.
Monitor the oil level weekly, especially in winter. Oil consumption of up to 0.5 liters per 1000 km is considered acceptable for engines with high mileage, but for new cars this may indicate a defect. A consumption of less than 200-300 ml per 10,000 km is considered normal for a working VQ35 engine.
Use quality canisters and store any remaining oil for refilling. Keep 1 liter of oil at home, the same brand you use in your car. This will save you in case of a sharp increase in oil consumption before a long trip.
FAQ: Frequently asked questions from owners
What oil is best for a turbocharged Murano Z52?
For the VR30DDTT (turbo) engine, it is recommended to use synthetic oil with a viscosity of 5W-30 or 0W-30 with API SP approval. This will protect the turbocharger from high temperature coking.
Is it possible to mix oils from different manufacturers?
Strongly not recommended. Even with the same viscosity, different additive packages can react, forming a deposit. Mixing is permissible only in an emergency to get to the place of replacement.
Do I need to flush the engine before changing the oil?
If you change your oil regularly and use a quality product, flushes are not necessary. They can damage seals in older engines. Flushing is required only when switching from mineral oil to synthetic oil on engines with high mileage.
How often should the oil filter be changed?
The oil filter must be replaced at every oil change. This is critical to ensure clean oil circulation and protect the phase control hydraulics.
What is the oil volume in the VQ35DE engine?
The oil volume in the VQ35DE engine (with filter replacement) is approximately 4.8 - 5.0 liters. For a complete replacement, it is recommended to purchase a 5-liter canister or two 4-liter canisters (depending on the model year).
