Owners of crossovers with powerful gasoline engines are often faced with the question: how power-hungry will their car be in real conditions? For model Nissan Murano third generation with a 3.5-liter engine, this issue is especially acute, since the figures declared by the manufacturer often diverge from what the speedometer and meter at the gas station show. Many drivers buy this car for the sake of dynamics and comfort, but forget that they have to pay for it at every gas station.
If you are considering purchasing Murano with mileage or already own it, it is important to understand that fuel consumption - this is not a fixed value. It depends on many variables: from driving style to the condition of the transmission and the quality of the road surface. In this article, we will analyze the real numbers shown by the owners and find out how you can slightly reduce the appetite of this powerful machine.
Stated performance versus actual use
The factory data indicated in the technical documentation always looks optimistic. For Nissan Murano with a 3.5-liter V6 engine (modification VQ35DE), the manufacturer promises performance that can only be achieved on ideal testing grounds with a strictly regulated driving cycle. The combined cycle shows a figure of about 9-10 liters per 100 kilometers, which sounds very attractive for such a heavy crossover.
However, in an urban environment, where there is constant acceleration, traffic jams and idling, the numbers change dramatically. Real fuel consumption in the city for Nissan Murano 3.5 rarely drops below 14-15 liters, and in the summer with the air conditioning running it can reach 17-18 liters. This is the price for powerful gasoline engine and a heavy body structure that requires considerable effort to accelerate.
It is interesting to note that the behavior of the car on the highway is different from urban conditions. When driving uniformly at a speed of 90-100 km/h, the engine operates in optimal mode and consumption decreases. But as soon as the speed exceeds 130 km/h, the aerodynamic drag increases sharply, and fuel consumption begins to increase again, often reaching 12-13 liters per 100 km.
Factors influencing the crossover's appetite
Why are two the same? Nissan Murano Can people with the same mileage consume different amounts of fuel? The answer lies in the individual operating conditions and technical condition of the components. Driving style plays a key role: aggressive acceleration with the gas pedal pressed forces the injection system to deliver the maximum amount of mixture, which instantly increases consumption.
The condition of the transmission is also critical. Automatic transmission CVT (stepless variator) in Murano tuned to be smooth, but if it requires maintenance or has problems with the torque converter, torque transmission efficiency drops. This forces the engine to work harder even at moderate speeds, increasing fuel consumption for no apparent reason.
- 🔧 Technical condition: clogged fuel injectors or old spark plugs can increase consumption by 10-15%.
- 🌡️ Weather conditions: in winter, consumption is always higher due to engine warming, stove operation and the use of winter tires.
- 🚗 Tire pressure: Insufficient tire pressure increases rolling resistance, causing the engine to spend more energy moving.
Don't forget about the quality of the fuel. Using low octane or contaminated gasoline may cause the engine control system to malfunction. The ECU (electronic control unit) tries to compensate for detonation or a lean mixture by adjusting the ignition timing, which ultimately leads to overshoot.
⚠️ Attention: Ignoring the signals from oxygen sensors can lead to the injection system supplying too rich a mixture, which will not only increase consumption, but will also quickly damage the catalyst, which is not being repaired. Nissan Murano is very expensive.
Comparative table of consumption in different modes
To clearly show the difference between stated and actual performance, we collected data from actual owner reports. These numbers will help you get a good idea of how much gas you'll have to buy. Note that even within a single mode, the spread can be significant.
| Operating mode | Claimed consumption (l/100km) | Real average consumption (l/100km) | Maximum consumption (traffic jams/winter) |
|---|---|---|---|
| Urban cycle | 11.5 - 12.0 | 15.0 - 16.5 | 18.0 - 19.5 |
| Route (90-100 km/h) | 7.5 - 8.0 | 9.5 - 10.5 | 11.0 - 12.0 |
| Mixed cycle | 9.0 - 9.5 | 12.5 - 13.5 | 15.0 - 16.0 |
| Dynamic ride | - | 17.0 - 19.0 | 20.0+ |
As can be seen from the table, the difference between the passport data and reality is from 3 to 5 liters per 100 km, depending on conditions. This is a significant amount, which adds up to a round figure over a year of operation. In metropolitan traffic jams, the fuel consumption of a Nissan Murano 3.5 can exceed 20 liters per 100 kilometers when parked for a long time with the engine running.
- Up to 14 liters
- 14-16 liters
- 16-18 liters
- More than 18 liters
Seasonal variations and climate influences
The winter period becomes a real test for owners Nissan Murano. In the cold season, the engine takes longer to warm up, and the transmission fluid becomes more viscous, which increases the resistance inside the variator. In addition, the use of a preheater or prolonged warming up in cold weather directly affects average fuel consumption per month.
Owners often note that at air temperatures below -15°C, fuel consumption in the city increases by 10-15% compared to the summer. This is due not only to warm-ups, but also to the fact that in winter, electrical appliances are used more often: heated seats, mirrors, steering wheel and windshield, which creates additional load on the generator and engine.
- 🧊 Winter tires: softer compound and aggressive tread increase rolling resistance.
- ⛽ Fuel quality: in winter, additives are often added to gasoline, which can change its density and combustion.
- 🌬️ Aerodynamics: open windows in the heat or using a roof rack in winter also affect performance.
In summer the situation improves slightly, but turning on the air conditioner again returns the numbers to the high consumption zone. The air conditioning compressor takes a significant portion of engine power, especially at low speeds and in traffic jams, forcing the engine to work harder.
To minimize winter fuel consumption, use high-quality motor oil with low viscosity (for example, 0W-30 or 5W-30) so that the engine reaches operating temperature faster and reduces friction in transmission components.
How to reduce fuel consumption without losing dynamics
You can reduce the appetite of a powerful crossover, but this will require changing some habits and monitoring the technical condition of the car. The main secret of saving is smooth driving. Avoid sudden starts and braking, try to keep your distance and anticipate the situation on the road so as not to use the brakes again.
It is important to monitor tire pressure. Underinflated wheels create enormous resistance, especially on heavy vehicles. Nissan Murano. Check your blood pressure regularly, especially before a long trip. The optimal pressure recommended by the factory is usually indicated on a sticker in the driver's door opening or in the owner's manual.
☑️ Checklist for reducing fuel consumption
It is also worth paying attention to aerodynamics. Remove roof rails and boxes when not in use. The extra load on the roof sharply worsens the streamlining, and at high speeds the engine is forced to spend more energy to overcome air resistance. This is especially true for Murano, which has a high windage.
⚠️ Attention: Do not try to save on oil or fuel by buying the cheapest analogues. Cheap, high-viscosity oil increases engine friction, and low-quality gasoline disrupts the combustion process, which in the long run will lead to even higher consumption and costly repairs.
Driving smoothly and maintaining correct tire pressure can reduce fuel consumption by 10-15% without compromising the safety and comfort of your ride.
Features of CVT variator operation and consumption
Transmission Nissan Murano is a continuously variable transmission (CVT), which has its own operating characteristics that affect fuel consumption. Unlike classic automatic transmissions, the CVT tends to keep the engine in the optimal speed zone, which should theoretically save fuel. However, in practice this only works during quiet driving.
When you press the gas pedal sharply, the variator simulates gear shifting, raising the speed to maximum. At this moment fuel consumption increases sharply as the engine runs at high speeds without any real need. Many owners notice that in “Sport” mode or with aggressive driving, consumption increases by 2-3 liters.
To save fuel, it is recommended to use the mode Eco (if it is included in the package). In this mode, the electronics changes the gas pedal map, making it less sensitive, and forces the CVT to keep the speed lower. This makes for a smoother ride, but may feel sluggish to those accustomed to performance.
What is Eco mode in Nissan Murano?
In Eco mode, the engine management system limits power, makes the accelerator less responsive and shifts the CVT to earlier gear ratios, which helps save fuel but reduces acceleration dynamics.
It is also worth remembering the thermal mode of the variator. If you frequently skid or drive off-road, the CVT overheats and its performance decreases. Under these conditions, fuel consumption may be higher than normal as the cooling system and hydraulic pumps consume additional energy.
Diagnosis of high flow problems
If you notice that your Nissan Murano began to consume significantly more fuel than usual, it is necessary to carry out diagnostics. First check oxygen sensors (lambda probes). A faulty sensor can send incorrect data to the ECU, causing it to richen the mixture unnecessarily.
The second important component is the ignition system. Spark plugs on a V6 engine require replacement every 100,000 km, but if they are dirty or have a broken insulator, the spark will be weak. This leads to incomplete combustion of fuel, which simply flies into the exhaust pipe without doing any useful work.
- 🔍 Injector diagnostics: clogged injectors spray fuel unevenly, which impairs combustion.
- 🔧 Replacing the air filter: a clogged filter restricts the air supply, disrupting the fuel-air mixture.
- ⚙️ Checking the throttle: carbon deposits on the throttle can interfere with the operation of the idle speed control system.
Sometimes the problem may be with the fuel pump itself or the fuel pressure regulator. If the rail pressure is below normal, the engine will run unstable and consume more fuel to maintain power. In such cases, it is recommended to contact a specialized service to check the pressure.
When diagnosing increased fuel consumption, be sure to check the condition of the fuel filter and mass air flow sensor (MAF), since their contamination is one of the most common causes of excessive consumption on V6 engines.
Frequently asked questions from owners
Below are answers to the most popular questions that owners have. Nissan Murano 3.5 regarding fuel consumption. These answers will help you better understand the behavior of your car and avoid common operating mistakes.
What is the minimum fuel consumption that can be achieved on the highway?
With a quiet ride at a speed of 90-100 km/h and no headwind, you can achieve a consumption of about 9.5-10.0 liters per 100 km. Exceeding the speed to 120 km/h and above sharply increases consumption due to aerodynamic drag.
Does the type of fuel (AI-92 or AI-95) affect consumption?
The VQ35DE engine is designed for AI-95. The use of AI-92 can lead to detonation and the operation of the protection system, which enriches the mixture. This increases consumption and can damage the engine. It is recommended to use only recommended fuel.
How often do you need to change spark plugs to save fuel?
The original spark plugs on this engine last up to 100,000 km, but to maintain optimal fuel consumption it is recommended to check their condition every 50,000 km. The gap and condition of the electrodes directly affect the quality of combustion.
Does air conditioning affect fuel consumption in traffic jams?
Yes, significantly. In traffic jams, when the speed is low and the engine load is high, the air conditioning compressor takes up to 10-15% of the power, which can increase consumption by 1-2 liters per 100 km. In hot weather, it is better not to turn off the air conditioner completely, but to use the AUTO mode.
Why does fuel consumption increase in winter?
In winter, consumption increases due to prolonged engine warm-up, the use of a cabin heater, the operation of heaters and more viscous oil. Also, winter tires with high rolling resistance are often used in winter. The normal increase in consumption in cold weather is 10-20%.
Understanding the factors that affect your fuel consumption Nissan Murano, will help you plan your travel budget and respond to technical problems in a timely manner. Despite the high appetite of this powerful crossover, proper operation and care of the car will make its maintenance more comfortable for the wallet.
