Crossover operation Nissan Murano the second generation, known with the Z51 index, requires careful attention to the power units, especially the lubrication system. The VQ35DE and VQ35HR engines installed on this model are distinguished by their high power and complex design, which makes the quality of oil filtration a critical factor in the longevity of the engine. Neglecting replacement deadlines or using low-quality consumables can lead to expensive repairs.
Many owners are faced with a dilemma: install only original components or trust proven analogues. In the conditions of the modern spare parts market, where counterfeits are found everywhere, the correct choice of filter becomes not just a technical decision, but a matter of the safety of your car. We will analyze in detail all aspects related to oil filter for this model.
Design features of the Murano Z51 lubrication system
Engine lubrication system VQ35, characteristic of Nissan Murano Z51, designed to withstand high loads and temperature conditions. Unlike simple in-line engines, it is important to ensure stable oil pressure in all channels, including the system of phase regulators and hydraulic compensators. Oil filter in this chain it plays the role of the main cleaner, retaining metal shavings, wear products and carbon deposits.
A design feature is that the filter is located in a hard-to-reach place, often blocked by other units or subframe elements. This requires the master not only to know the design, but also to have a specific tool for dismantling it. Check valve in the filter must work flawlessly so that when the engine is stopped, the oil does not drain completely into the sump, providing instant lubrication the next time it is started.
It is important to note that the throughput of an element directly affects the operation VVT systems (changes in valve timing). A clogged or ineffective filter creates excess flow resistance, which can lead to phase errors and reduced draft. Therefore, regularly checking the condition of the filter is a mandatory procedure during any maintenance.
⚠️ Attention: Using a filter with an incorrect bypass valve setting can lead to oil starvation of the turbocharger (if installed) or phase regulators during sudden engine braking.
Original filter versus high-quality analogues
When selecting consumables for Nissan Murano Z51 many car owners prefer the original part with the article number 15208-65F0A. The original filter undergoes strict factory certification, guaranteeing compliance with all the manufacturer’s technical requirements for the filter element area and valve opening pressure. This is by far the safest option, but also the most expensive.
However, there are proven alternatives on the market that are not inferior in quality to the original, and sometimes even surpass it. Brands like Toyota (since it is a sister brand with similar quality requirements), Mahle, Champion or Knecht offer products that are often produced in the same factories as the original, but under a different brand. The main thing is to make sure that the part is genuine, since a fake can be more dangerous than no filter at all.
When purchasing an analogue, pay attention to the tightness of the sealing ring and the quality of the thread. Cheap Chinese copies often have defects that lead to oil leakage immediately after replacement. Sealing rubber must be soft, elastic and free from burrs or deformation. Never skimp on this element, as a loss of pressure in the lubrication system can kill the engine in a matter of minutes.

Criteria for choosing the right filter
To choose the perfect element for your crossover, you need to consider several technical parameters. First of all, this thread size and body height. For Nissan Murano For Z51, it is critical that all dimensions be met, otherwise the filter may not screw in or seal the connection. It is also worth paying attention to the material of the filter paper - it must withstand high temperatures and the aggressive chemical environment of the oil.
The key parameter is the opening pressure of the bypass valve. If it is too high, then during a cold start or the filter is clogged, the oil will bypass the cleaning, polluting the engine. If it is too low, the filter may deform under pressure. Bypass valve is the heart of the filter, and its calibration must be perfect.
Don't forget about the quality of the O-ring. It must be made of heat-resistant rubber that can withstand heat up to 120-150 degrees without loss of elasticity. In cheap models, the rubber often hardens or, conversely, softens and begins to flow. Sealant must be installed level, without distortion, to ensure tightness.
| Parameter | Original (Nissan) | Analogue (Mahle) | Budget (not recommended) |
|---|---|---|---|
| Valve opening pressure | 1.0 - 1.2 bar | 1.0 - 1.2 bar | 0.6 - 0.8 bar (unstable) |
| Filtration area | ~1200 cm² | ~1250 cm² | ~800 cm² |
| Seal quality | High | High | Low (risk of leakage) |
| Service life | 10-15 thousand km | 10-15 thousand km | 5-7 thousand km (risk of blockage) |
Why can't I use a filter from another model?
Different engines have different oil pressure and different flow rates. A filter from a less powerful motor may not be able to cope with the load, while a filter from a more powerful one may have a valve with incorrect opening force, which will lead to oil starvation or rupture of the housing.
Step-by-step instructions for replacing the filter
The process of replacing the oil filter Nissan Murano The Z51 requires some preparation and caution. First, you need to warm up the engine to operating temperature so that the oil becomes thinner and drains better. Then turn off the engine, place the car on a level surface and, if possible, lift it on a lift or use reliable supports. Drain plug and the filter are located in the lower part of the engine compartment.
Before starting work, be sure to prepare a container for used oil and clean rags. Unscrew the pan drain plug, let the oil drain completely, and then move on to the filter. Use a special puller if the filter is stuck, but try not to damage its housing to prevent rupture and leakage of residual oil onto the generator or belt. Puller should fit tightly around the body to avoid slipping.
Clean the seat on the engine of old oil and dirt. Apply some fresh oil to the new filter O-ring to ensure a seal and make removal easier in the future. Tighten the filter by hand until it touches the seal, and then turn it another half or three-quarter turn as indicated on the housing. Puff using a key can lead to deformation of the seal and leaks.
☑️ Preparation for replacement
⚠️ Attention: Never use a torque wrench to tighten the oil filter unless the manufacturer has specified the exact torque. Excessive force may strip the threads or damage the filter housing, resulting in an accident while driving.
Typical maintenance errors
One of the most common mistakes is using old O-rings. Some craftsmen or the owners themselves forget to remove the old rubber band from the filter housing before installing a new one. As a result, two rings are installed, which leads to a violation of the tightness and severe oil leakage. Double ring - this is a guarantee that after some time the oil level will drop sharply.
Another mistake is over-tightening the filter. Many people believe that "the tighter the better" and use the wrench with more force. This leads to deformation of the housing, especially if the filter is plastic, and makes its subsequent removal difficult. In the worst case, the threads in the motor housing can be stripped, which will require complex repairs. Hand tightening is the gold standard for most passenger cars.
Sometimes owners ignore checking the condition of the oil after changing it. If after the first trip you notice smudges on the new filter or the color of the oil has changed, you must immediately stop and check the tightness. Control inspection after 500-1000 kilometers it will help identify hidden problems. Also, do not forget about replacing the oil filter at the same time as changing the oil, otherwise the new filter will quickly become contaminated with old oil.
- 🚫 Never leave the old o-ring on the new filter.
- 🚫 Do not use a gas wrench to tighten unless there is a special puller.
- 🚫 Do not neglect checking the oil level a week after changing.
Before replacing the filter, take a photograph of its location and the condition of the supply pipes to avoid assembly errors and not damage the fragile elements of the crankcase ventilation system.
Replacement intervals and expert recommendations
The manufacturer recommends changing the oil filter every 10-15 thousand kilometers or once a year, whichever comes first. However for Nissan Murano For a Z51, especially one used in a city with traffic jams, it is worth reducing this interval to 7-8 thousand kilometers. Urban cycle with frequent starts and stops creates increased stress on the engine and oil.
If you frequently drive off-road or in dusty conditions, the replacement interval should also be shortened. Dust and dirt can clog the filter element more quickly, reducing its effectiveness. In such cases, it is recommended to use filters with increased dirt holding capacity. Oil quality also plays a role: synthetic oils allow you to increase the interval, but only if you use a high-quality filter.
Experts advise replacing the filter at every oil change, even if the mileage is short. This ensures that the lubrication system operates optimally. Regular maintenance is the key to ensuring that the engine VQ35 will last hundreds of thousands of kilometers without major repairs. Prevention always cheaper than engine repair.
Reducing the oil and filter change intervals in urban use is the best way to extend the life of the VQ35 engine, which is sensitive to lubricant quality.
Signs of a filter malfunction
You can understand that the filter has become unusable based on several signs. The most obvious is a decrease in oil pressure, which is indicated on the dashboard or through the diagnostic scanner. If the oil pressure light comes on when the engine is idling, this is a serious signal. Low pressure may mean that the filter is clogged and does not allow oil to pass through, or the valve does not open.
It is also worth paying attention to extraneous sounds in the engine. Knocks from hydraulic compensators or phase regulators may indicate insufficient lubrication due to a clogged filter. Noisy engine on a cold one, which does not go away after warming up, is a reason to immediately check the condition of the filter and oil. Ignoring these symptoms can lead to scoring in the cylinders.
An external inspection of the filter can also give a clue. If traces of oil are visible on the housing, it means the seal is broken or the filter is cracked. If the filter is swollen, this indicates that the bypass valve cannot cope with the pressure. Bloating of the body - This is an emergency situation that requires immediate engine shutdown. Never continue driving when the oil pressure light comes on, even if it happens for a short time.
