Owners of crossovers with powerful naturally aspirated engines often encounter unexpected numbers on the on-board computer. Nissan Murano third generation with a 3.5 liter engine (model VR35DE) is a car that combines dynamics and comfort, but requires a serious approach to the issue of refueling. Many buyers are wondering how the fuel consumption declared by the manufacturer corresponds to real operating conditions in Russian cities and on country roads.
Understanding how it works fuel injection system and how does it affect transmission geometry CVT will help you avoid financial surprises. In this article, we will analyze not only dry numbers, but also the factors that cause the gasoline tank needle to drop faster than expected. You'll find out why aerodynamics plays a role even at low speeds and how engine settings affect the bottom line.
Stated figures versus actual operating conditions
The manufacturer in the technical documentation indicates average values obtained under ideal laboratory conditions. For Nissan Murano with a 3.5 liter engine, factory figures usually range from 9 to 11 liters per 100 km on the highway and about 14-15 liters in the combined cycle. However, these numbers rarely match what you'll see at a gas station in real life.
In city traffic jams, where the engine is idling or under frequent acceleration, fuel consumption increases sharply. Atmospheric engine large volume requires a lot of fuel to maintain torque when starting from a standstill. If you live in Moscow or St. Petersburg, be prepared for the fact that the actual consumption will be significantly higher than the passport one.
Many drivers notice that with an aggressive driving style, the numbers can reach critical values. This is due to the fact that the electronic control unit (ECU) enriches the mixture to quickly gain speed. It is important to understand that transmission characteristics CVTs also affect this process, as the CVT strives to maintain optimal speed, which sometimes leads to increased consumption when the gas pedal is pressed hard.
Factors influencing fuel consumption in the city
City cycle is the most difficult mode for any car with a large engine. Traveling short distances, when the engine does not have time to warm up to operating temperature, is a major factor in excessive consumption. Cold engine consumes more fuel as the control system supplies a richer mixture for stable operation.
The second critical factor is the traffic jam. In start-stop mode with air conditioning and electrical appliances running, fuel consumption can exceed 18-20 liters per 100 km. This is normal for a crossover weighing more than two tons with a 3.5-liter engine. The engine runs, but the car does not move, burning gasoline in vain.
- 🚦 Frequent stops at traffic lights increase the engine idling time.
- ❄️ The operation of the air conditioner and heater in winter or summer creates additional load on the engine.
- 🎒 Extra weight in the trunk and on the roof of the car requires more energy to accelerate.
Particular attention should be paid to the quality of the fuel and the condition of the filters. A dirty air filter disrupts the balance of the fuel-air mixture, which leads to a decrease in efficiency and increased consumption. Regular diagnostics ignition systems also helps maintain engine efficiency at the proper level.
⚠️ Warning: Do not ignore the Check Engine light. Even a minor error in the engine management system can lead to excessive fuel consumption of up to 15-20% without visible external symptoms of failure.

Fuel consumption on the highway and the influence of speed
Out of town Nissan Murano reveals its potential for efficiency, but only if a certain speed limit is observed. When driving at a speed of 90-100 km/h, the engine operates in the optimal speed range, and fuel consumption can drop to 8-9 liters per 100 km. The CVT effectively keeps the engine in the zone of minimum specific consumption.
However, as soon as you exceed the speed of 110-120 km/h, consumption begins to increase exponentially. This is due to an increase in aerodynamic drag. The crossover does not have the best aerodynamics, and at high speeds the engine is forced to work harder, burning more gasoline to overcome air resistance.
Long-term driving on the highway also depends on the condition of the tires and their pressure. Underinflated tires increase rolling resistance, which inevitably affects fuel efficiency. Check tire pressure before a long trip - this is an easy way to save a few liters of fuel.
It is important to note that using cruise control on a flat section of the highway helps stabilize speed and avoid unnecessary throttle changes. This is especially true for cars with a variator that can “float” in speed in the absence of clear control from the driver.
Maintenance and its role in savings
Proper maintenance is the key to stable fuel consumption. The 3.5 liter engine is sensitive to the condition of the spark plugs and coils. Misfires or unstable operation of one of the cylinders immediately leads to a loss of power and increased fuel consumption. It is recommended to change spark plugs every 40-50 thousand kilometers.
Oil in the engine and variator also plays an important role. Using oil with the wrong viscosity increases internal friction in the components, causing the engine to work harder. For Nissan Murano The manufacturer recommends certain specifications, compliance with which is critical to durability and economy.
☑️ Vehicle condition monitoring
The cooling system and thermostat must work properly. If the engine does not reach operating temperature or, conversely, overheats, the electronics adjust the mixture in a non-optimal manner. Thermostat with a stuck valve can cause constant increased fuel consumption.
- ⛽ Use only fuel recommended by the manufacturer (AI-95 or AI-98).
- 🛠️ Check the condition of the injectors and oxygen sensors at every maintenance.
- 🔧 Keep the throttle body clean to avoid an unstable idle.
Comparison with other modifications and competitors
Comparing Nissan Murano 3.5 compared to other crossovers in the class, it can be noted that it is not a leader in efficiency, but it is not an outsider either. Competitors with smaller turbocharged engines may show better numbers in the city, but lose in dynamics and smoothness on the highway.
The naturally aspirated V6 delivers linear thrust and reliability that often outweighs the disadvantages of increased consumption. The table below shows a comparison of actual fuel consumption figures for various power units under similar operating conditions.
| Engine model | Volume (l) | City (l/100km) | Route (l/100km) |
|---|---|---|---|
| Nissan Murano (V6) | 3.5 | 15-18 | 9-11 |
| Toyota Highlander (V6) | 3.5 | 14-16 | 8-10 |
| Chevrolet Traverse (V6) | 3.6 | 16-19 | 9-12 |
| Nissan Murano (Turbo 4cyl) | 2.0 | 12-14 | 7-9 |
As can be seen from the data, the difference between 3.5 and 2.0 liters is significant, especially in the urban cycle. However, for those who value performance and overtaking power, the V6 remains the preferred choice. Engine power at 249 hp allows you to feel confident on the road, which justifies the increased appetite for many owners.
Why can a variator increase consumption?
CVTs sometimes operate in a "floating" rev mode if the transmission settings are not optimized for driving style, which can lead to inefficient fuel use during sharp maneuvers.
⚠️ Attention: If fuel consumption suddenly increases by 3-4 liters without changing your driving style, check the mass air flow sensor (MAF) and lambda probes, as their incorrect operation is a common cause of excessive consumption.
Before a long trip to the highway, it is recommended to carry out an “aerodynamic cleaning”: remove the roof rack and remove unnecessary objects from the interior to reduce weight and air resistance.
Ways to optimize fuel consumption
There are a number of proven methods that can reduce fuel consumption without major intervention in the design of the car. First of all, this is a change in driving style. Smooth pressing of the gas pedal and early engine braking can save up to 10-15% of fuel.
Using Eco mode, if available on your trim, also helps optimize throttle and CVT performance. The system limits sudden acceleration and changes gear shifting patterns, making driving smoother and more economical.
Do not forget about loading the car correctly. Excess weight in the trunk is extra energy that the engine must spend accelerating. If you do not plan to transport cargo, clear the luggage compartment of unnecessary items. Vehicle weight directly affects inertia and flow.
A smooth driving style and timely maintenance are two main factors that help reduce the actual fuel consumption of the Nissan Murano 3.5 to the lowest possible values.
FAQ: Frequently asked questions about fuel consumption
What is the minimum fuel consumption you can expect from the Murano 3.5 in the city?
Under ideal conditions, with no traffic jams and quiet driving, the minimum consumption can be about 13-14 liters per 100 km. However, in reality, the average value in the city is often in the range of 15-17 liters.
Does using winter tires affect fuel consumption?
Yes, winter tires, especially studded ones, have greater rolling resistance, which can increase fuel consumption by 0.5-1.5 liters compared to summer tires. Also, the heavy rim with spikes adds unsprung weight.
Do I need to warm up the engine before driving to save fuel?
Prolonged warm-up at idle speed (more than 2-3 minutes) is not recommended and only increases consumption. It is optimal to start the engine, wait 30-60 seconds for the speed to stabilize and start driving in quiet mode while the engine warms up.
Is it possible to reduce consumption by using AI-98 fuel?
The use of AI-98 can slightly improve dynamics and reduce detonation, but it does not provide a significant reduction in fuel consumption. The engine ECU adapts to the quality of the fuel, and the difference in consumption will be minimal or unnoticeable.
Why does the on-board computer show one consumption, but in practice it turns out to be different?
The on-board computer often calculates fuel consumption "in flight", without taking into account the time spent idling or refueling before the tank is full. For accurate data, it is better to use the “until the tank is full” method - fill the tank full, reset the mileage counter and fill it again after a certain mileage.
To summarize, we can say that Nissan Murano The 3.5 is a car that requires a conscious approach to fuel consumption. Real consumption in the urban cycle rarely falls below 15 liters, and this should be taken into account when planning your budget for car maintenance. However, this crossover's comfort, performance and reliability make it one of the most popular choices in its class, despite its high running costs.
Proper maintenance, careful driving and the use of quality materials will help you maintain optimal performance. Remember that each car is individual, and your personal figures may differ from the market average depending on operating conditions and the condition of a particular vehicle.
