Selecting the correct amount of lubricant for your Nissan Murano first generation (Z51 body) is a critical maintenance step. Many owners mistakenly believe that it is enough to simply add fluid to the maximum on the dipstick, but the exact factory standards specified in the technical documentation ensure optimal operation of the lubrication system under load.
The VQ series engines installed on this model are characterized by high operating temperatures and specific viscosity requirements. An incorrect volume can lead to oil starvation during sudden maneuvers or, conversely, to increased pressure and destruction of the seals. In this article we will analyze the technical nuances that are relevant for 3.5-liter engines.
Understanding how many liters of fluid your car requires will help you avoid mistakes when replacing it yourself. Drivers often do not take into account the volume remaining in the oil filter and system channels, which leads to incorrect level readings after warming up.
Technical characteristics of VQ35DE series motors
Under the hood of the crossover Nissan Murano Z51 the most common gasoline engine VQ35DE. This is a 6-cylinder unit with a volume of 3.5 liters, which is famous for its power and dynamics. For its correct operation, it is necessary to comply with strict lubrication regulations, since the system has a complex channel design.
The manufacturer provides basic numbers, but they may vary depending on the year of manufacture and the presence of certain modifications to the intake manifold. The standard filling volume when replacing with a filter is about 4.8β5.0 liters. This value is the starting point for any service.
It is important to take into account that when the engine is completely disassembled (overhaul), the volume increases, since all internal cavities are washed. In such cases, up to 5.5 liters of liquid may be required. However, for scheduled maintenance it is enough to focus on standard indicators without exceeding them.
- Motor VQ35DE requires oil with a viscosity of 5W-30 or 10W-30
- The lubrication system includes an oil cooler, increasing the overall volume
- Oil pressure is monitored by a sensor connected to the dashboard
β οΈ Attention: Insufficient engine oil volume Nissan Murano can lead to scoring in the cylinders due to overheating of the piston group, since the engine cooling system is closely connected with the lubricant circulation.
Some owners wonder if the type of transmission affects the amount of oil in the engine. The answer is no, but
Precise filling volumes for different conditions
When buying oil, you should always take a container with a small reserve. A standard 4-liter canister will not cover the needs of the motor, so the optimal solution would be to purchase one 5-liter canister or a 4+1-liter combination. This will allow you to accurately bring the level to normal.
There is a nuance regarding warming up the engine before checking the level. Cold oil takes longer to drain into the sump than hot oil, so checking βcoldβ may show an overestimated level. The correct technique involves warming up to operating temperature, stopping the engine and waiting 5-10 minutes.
If you are planning a trip in difficult climate conditions, the volume may require adjustments towards minimum tolerances to avoid foaming of the liquid under extreme loads. However, as a rule, factory standards are universal for most regions.
| Parameter | Meaning | Note |
|---|---|---|
| Basic volume (with filter) | 4.8 l | Standard replacement |
| Volume without filter | 4.4 l | When changing only the oil |
| Recommended viscosity | 5W-30 | For temperate climates |
| Recommended viscosity | 10W-30 | For hot climates |
| Oil cooler capacity | ~0.4 l | Included in the total volume |
Please note that the table shows average values. The actual volume may differ by 100-200 ml depending on the condition of the tray and the history of previous repairs. Always check the dipstick level after filling.

- 5 liters
- 6 liters
- By liters in bottles
Algorithm for correct replacement of lubricant
The replacement process requires care and consistency. First, you need to warm up the engine to operating temperature so that the oil becomes more fluid and completely drains from the system. Then the drain plug located on the oil pan is unscrewed.
Pay special attention to the condition of the drain plug and gasket. The metal or copper washer will deform over time and may leak oil. It is recommended to change it every time the lubricant is changed to avoid future leaks.
After draining the old oil, the oil filter must be replaced. On the engine VQ35DE the filter is located in a hard-to-reach place, often requiring the removal of protective elements or the use of special keys. Do not overtighten the new filter, just screw it in by hand until it stops.
βοΈ Preparing for an oil change
New oil should be poured through the neck using a funnel. Take your time, pour gradually, controlling the volume. First fill in 4.5 liters, then run the engine for a couple of minutes to allow the oil to flow through the system and fill the filter.
After stopping the engine, wait 10 minutes and check the level with a dipstick. If the level is below the mark MAX, add the remaining amount. If it is higher, drain off the excess, since overfilling is no less dangerous than underfilling.
- Use only original filter Nissan or high-quality analogues
- Do not mix oils of different manufacturers and specifications
- Check the condition of the oil filler cap gasket
β οΈ Attention: Never start the engine immediately after filling the oil without first checking the level with a dipstick, as this may lead to water hammer in the system or oil release through the ventilation.
Influence of climate on the choice of volume and viscosity
Climatic conditions play an important role in the choice of oil. For regions with severe winters, where temperatures drop below -25Β°C, it is recommended to use oil marked 0W-30 or 5W-40. This will ensure rapid pumping through the channels during a cold start.
In hot climates where the air temperature exceeds +30Β°C, the viscosity of the oil may increase, which requires the use of compounds 10W-40. However, the standard 5W-30 remains the most versatile choice for most operating conditions Nissan Murano.
The volume of oil does not change, but its behavior in the system changes. Thick oil in hot weather can create increased resistance, which increases the load on the oil pump. Liquid oil in the cold may not have time to create the necessary pressure.
How does volume change when the engine overheats?
If there is severe overheating, some of the oil may evaporate through the crankcase ventilation system. In this case, the volume decreases and refilling is required. It is also possible that the oil can be diluted by fuel if the injectors are faulty, which visually increases the volume but reduces the quality of the lubricant.
It is important to note that the crankcase ventilation (PCV) system on the engine VQ35DE sensitive to oil condition. Contaminated oil can clog the valve, causing excess pressure and squeezing out the seals.
Common maintenance mistakes
One of the most common mistakes is ignoring the filter volume recommendation. Some technicians simply change the oil, leaving the old filter, which leads to mixing of old and new oil in the filter volume, reducing the effectiveness of the replacement.
Another mistake is using an incorrectly specified oil. Nissan engines require specification API SN or newer. Using outdated standards can result in rapid oil oxidation and sludge formation.
Some owners try to save money by adding cheap oils to expensive ones. This is strictly prohibited, as different additive packages may react, causing coagulation and sedimentation, which will clog the oil passages.
Another mistake is incorrect installation of the drain plug. If the threads are broken, the pallet will need to be repaired, which entails significant financial costs and time.
Before unscrewing the drain plug, be sure to place a container under the engine. Hot oil can burn your hands, so wear gloves and eye protection.
Specifics of oil level diagnostics on Z51
Checking the oil level at Nissan Murano has its own characteristics. The dipstick is located at the rear of the engine, closer to the passenger compartment, which sometimes makes access difficult. For convenience, it is recommended to use an extended probe or a flashlight.
Level indication should only be done on a flat surface. If the machine is parked on a slope, the readings will be incorrect. This can lead to the mistaken decision to add oil that is not actually needed.
Modern monitoring systems may not show the exact level, so a mechanical dipstick remains the most reliable tool. Visually assessing the color of the oil is also important: black oil doesn't always mean it's bad, but the presence of metal shavings is a warning sign.
- Check the level at hot engine 5-10 minutes after stopping
- Clean the probe before each measurement for accuracy.
- Make sure there is no emulsion (white foam) on the dipstick
If the oil level drops quickly between changes, it may indicate a leak or waste. Engine oil waste VQ35DE often associated with wear on the oil rings or the turbine (if installed).
Final recommendations and conclusion
Maintaining the correct amount of engine oil Nissan Murano Z51 is the key to the durability and reliability of your car. Regular replacement using quality materials and exact quantities will prevent costly repairs in the future.
Remember that the VQ35DE engine requires quality maintenance. Saving on oil or filter can result in serious problems. Use only trusted brands and follow the manufacturer's instructions.
Check the oil level regularly before long trips. This is a simple procedure that can save your engine from catastrophic consequences down the road. Taking care of the technical condition of your car always pays off.
Accurate adherence to the oil volume of 4.8 liters when changing with a filter and the use of high-quality 5W-30 oil are the main factors for the long life of the VQ35DE engine.
How many liters of oil are needed for a complete oil change with filter?
For a complete oil change with filter replacement in the VQ35DE engine, you need to purchase 5 liters of oil. The standard refill volume is 4.8 liters, so a 5-liter canister will provide the necessary reserve for topping up and checking the level.
Is it possible to mix oils of different brands?
Mixing oils of different brands, especially those with different API standards or viscosity, is strictly not recommended. This can lead to deposits, additive degradation and poor lubricity, which will damage the engine.
How often should you change the oil in your Nissan Murano Z51?
The recommended oil change interval is 10,000 km or once a year, whichever comes first. When operating in difficult conditions (city traffic, dust, short trips), the interval should be reduced to 7,000 km.
What should I do if the oil level is above the MAX mark?
If the oil level is above the MAX mark, you must drain the excess through the drain hole or use a medical syringe with a tube through the neck. Overfilling the oil can lead to foaming, loss of pressure and damage to the seals.
Which oil filter is better to choose?
The best choice is the original Nissan oil filter (code 15208-65F0A or equivalent). High-quality analogues from the Mann, Mahle or Purflux brands are also suitable, which provide effective filtration and withstand operating pressure.
