Oil filter Nissan Murano Z50: selection, replacement and nuances

Crossover owners Nissan Murano second generation, known in the Z50 body, are often faced with the need to choose the right consumables for the engine. This car, equipped with reliable VQ series engines, requires special attention to the lubrication system, since the life of the expensive unit directly depends on the quality of the filter. Ignoring replacement dates or installing a low-quality product can lead to oil starvation and failure of the crankshaft liners.

Choosing the right part isn't just about buying a box labeled "for Nissan." It is necessary to take into account the design features of the VQ35DE or VQ35HR motor, which were installed on Murano between 2003 and 2008. A wise choice will ensure stable oil pressure, clean lubricant and smooth engine operation even under high loads in city traffic or on the highway.

Design features of filtration on Murano Z50

Lubrication system for VQ series engines installed on Nissan Murano, has its own unique characteristics that dictate the requirements for the filter element. Unlike many other Japanese cars, it uses a filter with high operating pressure and a specific thread. The standard element must withstand the pressure drops that occur during a cold start, when the oil viscosity is at its maximum.

The key element is check valve, preventing oil from draining from the filter into the crankcase after stopping the engine. If this mechanism does not work correctly, the next time you start it you will hear a characteristic hum from the turbine or hydraulic compensators due to a short-term loss of pressure. Also critical bypass valve, which opens when the filter element is clogged, allowing dirty oil to pass through, but preventing it from entering the oil channels.

The original filter from the manufacturer often has a metal housing with high quality welding and a reliable gasket. However, many owners choose analogues, which offer comparable performance at a lower price.

Original spare parts and best alternatives

When choosing consumables for Nissan Murano Z50, most car owners are inclined to buy the original product with catalog number 15208-65F0A. This filter has passed all factory tests and is guaranteed to meet the requirements of Nissan engineers. His productivity tested over hundreds of thousands of kilometers, making it a safe choice for those who don't want to experiment with brands.

However, the auto parts market offers many worthy replacements, which often surpass the original in the quality of the filter cloth. Among the popular brands it is worth highlighting Tenneco (Delphi), which is the actual manufacturer of original Nissan filters, as well as Cosmo and JS Asakashi. These companies use modern synthetic materials that provide a high degree of purification.

• ✅ Nissan (original) - standard quality, but high price and risk of fakes.
• ✅ Tenneco / Delphi — direct supplier, identical design, excellent price.
• ✅ JS Asakashi - Japanese brand with excellent filter material.
• ✅ Cosmo - a reliable option with good throughput.

You should avoid cheap Chinese analogues of unknown origin, which often have a poor-quality gasket or a weak check valve. Installing such a filter may result in oil pump will run idle, pumping air instead of lubricant. The most critical mistake is using a filter with an incorrectly selected bypass valve, which, if heavily contaminated, instantly damages the engine.

Replacement intervals and diagnostics

Standard maintenance schedule for Nissan Murano The Z50 requires oil filter replacement every 10,000 kilometers or once a year. However, in Russian realities, taking into account the quality of fuel and dust on the roads, it is better to reduce this interval to 7,000 - 8,000 kilometers. Frequent replacement is the cheapest way to extend the life of your engine.

At each oil change, it is necessary to visually inspect the old filter. If the body shows signs of corrosion, cracks or damaged threads, this is a signal that it is necessary to check the condition of the engine or the quality of the previous replacement. It is also worth paying attention to the color and consistency of the old oil - the presence of metal shavings or emulsion requires in-depth diagnostics.

The table below shows the main parameters that you should pay attention to when choosing and checking a filter:

Parameter	Value for Murano Z50	Comment
Thread size	M20x1.5	Standard thread for VQ motors
Height	88-92 mm	Affects the amount of retained oil
Case diameter	70-75 mm	Important for placement in the engine compartment
Valve opening pressure	0.8 - 1.2 bar	Critical for protection against oil starvation
Filter type	Drain (Spin-on)	Replaced entirely together with the housing

⚠️ Attention: If you operate the car in taxi mode or often stand in traffic jams, the replacement interval should be reduced to 5,000 kilometers. Engine operation at low speeds and high temperatures significantly accelerates oil aging and filter contamination.

Step-by-step instructions for replacing the filter

The process of replacing the filter Nissan Murano Z50 does not require complex specialized equipment, but has its own access nuances. The filter is located at the bottom of the engine, on the front passenger side, and is often hidden under a plastic fender liner or protective shield. First, you need to warm up the engine to operating temperature so that the oil becomes less viscous and flows into the sump faster.

Before starting work, make sure that you have all the necessary tools and consumables. You will need a wrench to remove the filter (oil puller), a container to drain the used oil, a new gasket (if it comes separately) and, of course, the filter itself. Be sure to have a rag ready to clean the area around the filter neck to prevent dirt from getting into the engine.

First you need to drain the old oil from the pan by unscrewing the drain plug. Then, using a puller, carefully unscrew the old filter. Be careful as there may be a lot of hot oil left inside. If the filter is stuck, do not try to pierce it with a screwdriver from the inside, so as not to damage the seat on the cylinder block.

Clean the seating surface on the engine from any old gasket residue and dirt. Apply a thin layer of fresh oil to the rubber gasket of the new filter - this will ensure a tight seal and ease of unscrewing next time. Screw the new filter in by hand until it touches the gasket, then tighten it an additional 3/4 turn. Using a wrench for final tightening is not recommended as this may damage the gasket.

⚠️ Attention: Do not tighten the filter too much! The rubber gasket should compress under oil pressure and not be crushed by the metal housing. Over-tightening often results in stripped threads or deformation of the housing the next time it is replaced.

Nuances of oil selection and compatibility

The quality of the filter is closely related to the type of oil used. For engines Nissan Murano Z50 manufacturer recommends using synthetic oils with a viscosity 5W-30 or 5W-40 depending on the climate zone. The use of incompatible oils can lead to rapid clogging of the filter element or its destruction under the influence of aggressive additives.

Particular attention should be paid to oil tolerance. For VQ series motors, having a standard is critical API SN or ILSAC GF-5 (and higher). These standards guarantee the presence of additives that protect against carbon deposits and wear. Cheap mineral oils or oils with outdated approvals can negate the effectiveness of even the most expensive filter.

• ❌ Do not use Oils with a viscosity of 10W-60 are too thick for cold starts and stress the oil pump.
• ❌ Avoid mixtures of mineral and synthetic oils without clear instructions from the manufacturer.
• ❌ Do not use additives that change the viscosity of the oil, as they can clog the pores of the filter element.

If you are planning to switch from one brand of oil to another, it is advisable to flush the system or simply shorten the first change interval after changing the brand. This will remove any remaining old oil and additives that may react with the new components. The filter in this case acts as a trap for the formed sediments.

Can the filter be used with a different threaded connection?

No, using a filter with a different thread (such as from other Nissan brands) will result in a leak-proof installation. Even if the thread appears to be correct, the thread pitch may be different, causing the thread to leak or break on the first tightening.

Common maintenance mistakes

Many owners Nissan Murano make mistakes that reduce engine life. One of the most common is installing the filter without first lubricating the gasket. When dry, the rubber ring may twist or break when tightened, resulting in oil leakage immediately after starting the engine.

Another mistake is ignoring the condition of the drain plug O-ring. If you change the filter but forget to replace the copper ring on the pan plug, oil may begin to leak through the threads. This creates the appearance of a leak in the filter itself or the valve cover gasket, misleading the technician.

It is also worth noting the problem with low-quality tools. Using cheap pullers can tear off the ribs on the filter housing, making it impossible to unscrew it the next time. In this case, you have to drill out the housing or use special tools to remove jammed filters, which greatly complicates the procedure.

⚠️ Attention: Never leave the old gasket on the engine when installing a new filter. If it remains on the block and you put on a new one, the oil will come out under enormous pressure, since the double thickness of the gasket will not allow creating a tight connection.

Conclusion and final recommendations

Selecting and replacing the oil filter with Nissan Murano Z50 is a procedure that requires attention to detail and adherence to regulations. The use of high-quality consumables and proper performance of work guarantee long and trouble-free operation of the VQ engine. Do not skimp on filters, as the cost of replacement is not comparable to repairing an engine with oil starvation.

Remember that regular maintenance is the key to the reliability of your car. Check the oil level before every long trip and monitor the condition of the filters. Even the most expensive filter will not save you if the oil was not changed on time or low-quality fuel was used.

Following all recommendations will allow you to enjoy comfort and dynamics Murano for many years. If you doubt your abilities when replacing, it is better to entrust this work to professionals at a specialized service that has experience working with Japanese crossovers.
