Many luxury crossover owners such as Nissan Murano second generation (Z50 body), are often faced with the question of how autonomous their car is on long trips. Knowing the exact displacement of the fuel tank allows you to intelligently plan your routes, especially if you are traveling through sparsely populated regions or highways with rare gas stations. For this model, it is important to understand the difference between the passport data and real capabilities, which depend on many factors, including the condition of the engine and driving style.
Manufacturer Nissan designed the Z50's body design to be large enough to provide a balance between the car's weight and range. However, static figures from technical documentation do not always reflect the dynamics of real operating conditions. In this article we will look in detail at what tank volume installed at the factory, how modifications affect it, and what you need to know to maximize fuel efficiency.
Official fuel system specifications
During the production of a crossover Nissan Murano For the Z50, which was produced from 2002 to 2007, engineers provided a standard fuel tank volume of 80 liters. This figure is fixed for all modifications with a 3.5 liter V6 petrol engine (VQ35DE model range). This volume allows the car to cover significant distances without the need for frequent stops at gas stations, which is especially important for family trips.
It is important to note that technical documentation often indicates the full volume, not the useful volume. This means that when filling up to a full tank, you may end up with slightly less liters if the system already had residual pressure or if you refueled in cold temperatures. Fuel system Designed with safety in mind, it features special valves and level sensors to prevent overfilling and provide accurate readings on the instrument panel.
For owners Murano For the Z50, it is critical to understand that the reserve volume at which the Check Fuel light or low fuel light comes on is typically around 10-12 quarts. This leaves you with a range of approximately 100-120 kilometers depending on the driving mode, which gives you time to find the nearest gas station without the risk of stopping the engine on the highway.
Actual range and factors affecting autonomy
Knowing that tank volume is 80 liters, many owners try to calculate the ideal range by simply multiplying this volume by the average fuel consumption indicated in the passport. However, reality often makes its own adjustments. The VQ35DE engine is a powerful and voracious unit, especially in the urban cycle, where consumption can reach 15-18 liters per 100 kilometers and more.
Many variables influence actual autonomy. In winter, when using the stove and warming up the engine, fuel consumption increases. It is also worth considering the state of the car’s aerodynamics: if you have installed mud flaps, roof rack or high light transmission tint, air resistance will increase, which will reduce mileage per tank.
Driving style plays a decisive role. An aggressive driving style with sudden acceleration and braking can increase consumption by 20-30%. At the same time, smooth driving and maintaining a constant speed on the highway allow you to get closer to the passport data and significantly increase the distance that can be covered without refueling.
- 🛣️ Urban cycle: real consumption is 15–19 liters per 100 km, which gives a range of about 420–500 km.
- 🛣️ Suburban cycle: at a speed of 90–110 km/h, consumption drops to 10–12 liters, allowing you to travel 650–750 km.
- 🛣️ Mixed mode: the most likely consumption rate is 13–15 liters, providing a range of 530–600 km.
⚠️ Warning: Do not attempt to operate a vehicle with the low fuel light constantly on. This can lead to overheating of the fuel pump, which is cooled by gasoline, and its premature failure.
- Aggressive (sport mode)
- Calm (economy)
- Mixed (city + highway)
- Depends on the situation
Features of the design and location of the tank
Structurally, the fuel tank is Nissan Murano The Z50 is made from high-strength plastic, which reduces the overall weight of the vehicle and increases corrosion resistance compared to metal counterparts. It is located under the vehicle's underbody, between the rear wheels, which ensures optimal weight distribution and shock protection when driving over rough terrain.
Access to the tank filler is through a hatch located on the right side of the vehicle (passenger's side). This is a standard solution for right-hand drive versions and many left-hand drive models produced for the Japanese domestic market or export. The fuel filler cap has a secure lock that locks when the vehicle's central locking is closed, preventing unauthorized access.
The tank ventilation system includes an adsorber that traps fuel vapors and prevents their release into the atmosphere. When servicing your car, it is important to monitor the condition of the ventilation system valves, since their clogging can lead to difficulties when refueling or even to deformation of the tank due to pressure differences.
⚠️ Attention: When replacing the fuel filter or servicing the fuel supply system, be sure to relieve pressure in the line by turning off the fuel pump fuse and allowing the engine to run until it stops.
☑️ Checking the fuel system
The influence of modifications and configurations on displacement
The question is whether it changes tank volume depending on the configuration, is often a concern for buyers of used cars. For the Z50 body, the manufacturer did not provide different tank sizes for different versions (SE, SL, LE). All crossovers of this generation are equipped with a single tank with a capacity of 80 liters, regardless of the type of drive (front-wheel drive or all-wheel drive) and year of manufacture.
However, there are nuances associated with sales markets. For example, versions for the US or European markets may have minor differences in the design of the fuel system, but the displacement remains unchanged. Some owners try to install additional tanks, but this requires serious modifications to the bottom and safety system, which is not recommended without special skills.
When buying used Nissan Murano It is worth paying attention to the condition of the tank itself. After many years of use, the plastic may become brittle and the fasteners may become loose. The presence of leaks or the smell of gasoline in the cabin is an alarming signal that requires immediate contact to a service center.
- 🚗 Front-wheel drive: standard tank volume is 80 liters, the supply system is simplified.
- 🚗 All-Wheel Drive: tank volume 80 liters, components for torque distribution have been added.
- 🚗 Restyled versions: technically identical to pre-restyling, the volume has not changed.
⚠️ Attention: Do not try to modify the fuel system yourself by installing additional tanks. This compromises the structural integrity of the vehicle and can lead to a fire in an accident.
Why can't you overfill the tank?
If overfilled, gasoline may enter the ventilation system and adsorber, which will lead to clogging and costly repairs. Fuel may also leak through the valve while driving due to expansion when heated.
Recommendations for operation and maintenance
To ensure long fuel system life and accurate measurement fuel consumption It is necessary to use fuel of the appropriate octane number. For the VQ35DE engine, it is recommended to use AI-95 or AI-98 gasoline. Using low octane fuel can cause detonation, reduced power and engine damage.
Regular replacement of the fuel filter is a mandatory procedure. By car Nissan Murano The Z50 filter is often built into the fuel pump and cannot be replaced separately without removing the tank. However, there are external coarse filters that should be changed every 30-40 thousand kilometers to extend the life of the main filter.
Monitor the fuel level sensor readings. Sometimes the needle may “stick” or show incorrect data due to wear on the float. In such cases, it is recommended to carry out computer diagnostics and, if necessary, replace the fuel level sensor, which is assembled with the fuel pump.
If you plan to park your car for a long time (more than a month), it is recommended to fill the tank full and add a fuel stabilizer to prevent gasoline oxidation and sediment formation in the system.
| Parameter | Meaning | Unit of measurement |
|---|---|---|
| Total tank volume | 80 | liters |
| Reserve volume | 10-12 | liters |
| Recommended fuel | AI-95 / AI-98 | octane number |
| Consumption in the city (real) | 15-19 | l/100 km |
| Consumption on the highway (real) | 10-12 | l/100 km |
Diagnosing problems with the fuel system
If you notice that the actual range is significantly less than expected, or the fuel level sensor shows incorrect data, you need to carry out diagnostics. One common problem is wear on the fuel pump brushes, which leads to overheating and reduced performance.
It is also worth checking the operation of the adsorber. If the canister valve is stuck open, you may smell gasoline in the car or outside, and notice increased fuel consumption. If stuck in the closed position, the tank may begin to be “sucked” inward, which will make it difficult to open the filler cap.
For accurate diagnostics, it is recommended to use an OBDII scanner, which will allow you to read errors associated with the engine management system and fuel system. Errors such as “low fuel flow” or “level sensor malfunction” will help a specialist quickly localize the problem.
- 🔍 Checking the pressure in the fuel rail: the norm is 3.0–3.5 bar.
- 🔍 Adsorber diagnostics: checking the purge valve for jams.
- 🔍 Visual inspection of the wiring: checking the integrity of the fuel pump and level sensor wires.
Regular diagnostics of the fuel system and the use of high-quality fuel are the key to long engine operation and accurate level sensor readings.
