Crossover owners Nissan Murano second generation (Z51 body) are often faced with a dilemma when choosing consumables for the power plant. This car is equipped with powerful V6 engines that require a special approach to maintenance in order to maintain dynamics and efficiency over many years of operation. The wrong choice of lubricant can lead to accelerated wear of the cylinder-piston group and costly overhauls.
The manufacturer clearly regulates the requirements for the viscosity and chemical composition of the liquid. However, the market offers hundreds of options, from cheap fakes to premium synthetic compounds. To your Nissan Murano Z51 has remained a reliable companion, it is necessary to understand the difference between mineral, semi-synthetic and fully synthetic oils, as well as know the current specifications of the manufacturer.
Factory specifications and viscosity requirements
Engineers Nissan Motor Co. When developing the VQ series engines (VQ35DE and VQ35HR), operation over a wide temperature range was taken into account. For the Japanese climate and most regions of Russia, the optimal choice is an oil with a viscosity 5W-30. It is this index that provides the necessary balance between fluidity during a cold start and a protective film at engine operating temperatures.
In severe winters, when the temperature drops below -25Β°C, the use of lubricant is allowed 5W-20 or even 0W-20, if this is confirmed by the current manual. However, for summer or hot climates, it is strictly not recommended to reduce the viscosity below the standard, since the thin film may not withstand high loads under heavy operating conditions.
Compliance with API and ILSAC specifications is key. For motors Nissan Murano Z51 clearance is a prerequisite API SN or later (SP) and ILSAC GF-5 (or GF-6). These standards ensure deposit control, high temperature stability and compatibility with modern emission control systems.
Types of oils and their effect on engine life
There are three main types of motor oils that can be found on store shelves: mineral, semi-synthetic and synthetic. For a modern crossover with a V6 engine, mineral oils are completely excluded from the list of acceptable ones. Their molecular structure is not able to provide the necessary protection at high speeds and temperatures characteristic of engine operation. VQ35.
Semi-synthetics (SAE 10W-40) can only be considered if the car's mileage exceeds 200,000 km and there is noticeable oil loss. In other cases, the use of semi-synthetic compounds will lead to rapid oxidation and loss of protective properties. Fully synthetic oil is the only right choice for Nissan Murano.
Synthetics have a stable molecular structure that does not break down when exposed to high temperatures. This is critical for CVVT engines where the oil pump operates under high pressure. Unstable lubrication can lead to jamming of hydraulic tensioners and improper operation of camshafts.
- βοΈ Full synthetics ensure instant pumping through the channels during a cold start.
- π‘οΈ A high viscosity index protects camshaft bearings from wear in hot weather.
- π§Ή Modern additives effectively clean the engine of soot and sludge.
It is important to understand that a brand does not always guarantee quality. Even an expensive brand may be a counterfeit or the chemical composition may not be suitable for a particular model. Always check for official certification on the canister.
β οΈ Attention: Using oils with ACEA A3/B4 approval without confirming compatibility with Japanese engines can lead to clogging of the oil channels with fine particles of additives, since Japanese engines have narrower channel capacities.
Filling volume and replacement intervals
Accurate knowledge of the oil volume is necessary for the correct replacement procedure. Engine VQ35DE (early versions of Z51) requires 4.8 liters lubricant when replacing along with the filter. Later versions with engine VQ35HR They have similar parameters, but you should always check the level on the dipstick after refueling.
The oil change interval depends on operating conditions. Under ideal conditions, with quiet driving and short trips, the manufacturer recommends changing the oil every 10,000 km or once a year. However, in the conditions of Russian megacities with traffic jams, dusty roads and low temperatures, the interval should be reduced to 7,000 β 8,000 km.
Frequent oil changes prolong the life of the engine and maintain its power. Old oil loses its cleaning properties, combustion products and metal shavings accumulate in it. This creates an abrasive environment that acts like sandpaper inside the motor.
- Every 5000 km
- Every 7000-8000 km
- Every 10,000 km
- According to dealer regulations (15,000 km)
The best oil brands for Nissan Murano Z51
There are many manufacturers in the market whose products meet the specifications Nissan. You should focus on large international brands that have their own factories and strict quality control. The market leaders for Japanese cars are traditionally Mobil 1, Shell Helix, Liqui Moly and Idemitsu.
Original oil Nissan Genuine Oil often produced by major partners such as Idemitsu or ExxonMobil. If you buy a canister with a logo Nissan, make sure the label shows the correct viscosity index and tolerance. Often, the original packaging hides high-quality, time-tested synthetics.
Company Liqui Moly offers great options such as Molygen New Generation 5W-30, which contain special molybdenum additives to reduce friction. This is especially true for high mileage engines. Products Shell Helix Ultra has also proven itself to be a reliable solution thanks to PurePlus technology.
| Brand | Oil model | Viscosity | API clearance |
|---|---|---|---|
| Nissan Genuine | Motor Oil | 5W-30 | SN/GF-5 |
| Mobil 1 | Extended Performance | 5W-30 | SN/SP |
| Idemitsu | Zepro Touring | 5W-30 | SN/GF-5 |
| Liqui Moly | Molygen NG | 5W-30 | SN/GF-5 |
β οΈ Attention: Avoid buying oils in spontaneous markets or in dubious online stores without a guarantee. A fake can cost you engine repairs, since the canister may contain ordinary waste fluid with added dyes.
Before purchasing oil, check the production date on the canister. Synthetic oil has a shelf life of about 5 years, but it is better to use a product that was released no more than 2-3 years ago to ensure that the additives are active.
Replacement procedure and filter selection
The oil change process includes draining the used fluid, replacing the oil filter and adding new lubricant. It is important to allow the oil to drain completely, for which it is recommended to warm up the engine to operating temperature before starting work. This will reduce the viscosity and allow more contaminants to drain out.
Replacing the oil filter is mandatory at every oil change. The filter traps wear products and dirt. If you put a new filter in old oil or leave an old filter with new oil, the efficiency of the lubrication system will sharply decrease. For Nissan Murano Z51 original filters with article number are suitable 15208-65F0A or high-quality analogues from Mann-Filter, Oil Filter.
When adding new oil, use a funnel to avoid spilling fluid on a hot engine. After refueling, you need to start the engine and check if the oil pressure light on the dashboard comes on. Let the engine run for 2-3 minutes, then turn off and check the level on the dipstick.
βοΈ Oil change instructions
What to do if you overfilled the oil?|If the oil level exceeds the MAX mark on the dipstick, it is dangerous. Excess oil can cause the crankshaft to foam, causing loss of pressure and seal failure. In this case, it is necessary to drain the excess through the drain plug or with a syringe through the dipstick hole.-->
Don't forget to check the condition of the drain plug gasket. The metal washer tends to become deformed after several uses. If the gasket is damaged, leaks may occur, which will lead to low oil levels along the way.
Common maintenance mistakes
Many owners make common mistakes that shorten the life of the engine. One of the most common is saving on oil and filters. Cheap analogues often do not have the necessary additives to protect against corrosion and wear, which is critical for aluminum engine cylinder blocks VQ.
Another mistake is ignoring mileage. Oil degrades not only with time, but also with the number of engine hours. In traffic jams, the engine runs for a long time, but the car does not travel much. In such conditions, the replacement interval should be calculated based on engine hours, and not on the odometer.
It is also not recommended to mix oils of different brands or types. Even if both oils have the same viscosity, their additive package may be incompatible, which will lead to sedimentation and loss of protective properties. Never mix synthetics and semi-synthetics unless absolutely necessary..
- π« Do not use oils with a viscosity of 10W-50 or higher without consulting an engineer.
- π« Do not over-tighten the drain plug to avoid stripping the thread.
- π« Donβt ignore the color of the oil on the dipstick
black color is a sign of contamination, milky color is a sign of antifreeze.
β οΈ Attention: If you find emulsion (white foam) on the dipstick, stop using the vehicle immediately. This is a sure sign that coolant has gotten into the engine oil, which can lead to water hammer or bearing corrosion.
Owner Frequently Asked Questions (FAQ)
Is it possible to use 0W-20 oil in Nissan Murano Z51?
Yes, modern engines allow the use of 0W-20 oil, especially to save fuel. However, for older versions of VQ35DE engines with high mileage, it is recommended to stick to 5W-30 viscosity to ensure sufficient oil film thickness.
How often does the gearbox oil need to be changed?
Although the manufacturer claims a βmaintenance-freeβ CVT gearbox, experts recommend changing the oil in the CVT every 60,000 km. This will extend the life of the belt and torque converter, preventing costly repairs.
Do I need to flush the engine before changing the oil?
If you use high-quality synthetic oil and observe the change intervals, flushing is not required. Flushing oils can attack rubber seals and flush away deposits that block oil passages. It is better to use high-quality oils with detergent properties.
What is the oil volume in the VQ35HR engine?
The VQ35HR engine oil system capacity is approximately 4.8 liters when replaced with a filter. Always add 5 liters so you have room for refilling, but don't overfill.
Following the recommendations for choosing and changing oil is the key to long and trouble-free operation of your Nissan Murano.
