Complete guide to fuel consumption of Nissan Murano Z51: 3.5 Engine and CVT

Crossover owners Nissan Murano third generation (Z51 body) people often wonder about the real efficiency of the power plant. Equipped with a 3.5 liter naturally aspirated petrol engine and a continuously variable CVT transmission, the car strikes a balance between power and a comfortable ride. However, the appetite of such a motor can vary greatly depending on operating conditions and technical condition.

Many buyers rely on official passport data, which often looks optimistic. In reality fuel consumption depends on many factors: from the quality of the road surface to driving style. Understanding these nuances will help you avoid unpleasant surprises at the gas station and properly plan your budget for car maintenance.

In this article we will look at what numbers are the norm for Nissan Murano Z51, how the CVT affects gasoline consumption and what exactly can be done to reduce costs. We'll analyze real owner reviews and technical features of the VQ35DE engine to give you the full picture.

Official norms versus actual exploitation

The manufacturer indicates average values ​​that are achieved under ideal laboratory conditions. For the modification with a 3.5-liter engine and a CVT, the manufacturer declares consumption in the combined cycle of about 10.5–11 liters per 100 kilometers. However, in real life, these numbers rarely coincide with the readings of the on-board computer.

In the city, especially during rush hours, when you often have to stand in traffic jams, fuel consumption inevitably increases. The engine has to run at idle speed or in frequent acceleration mode, which is not provided for in the test cycle. In addition, climatic conditions, such as cold winters or overheating of the engine in summer with the air conditioning on, also make significant adjustments to the numbers.

On the track the situation looks more optimistic, but there are some nuances here too. At speeds above 110–120 km/h, the aerodynamic drag of the crossover increases sharply, forcing the engine to work under increased load. In such conditions, even the economical operating mode of the variator will not be able to keep consumption within the stated 8–9 liters.

⚠️ Attention: You should not completely trust the performance of the on-board computer if you have not reset its settings after a recent oil change or ECU firmware update. Data may be overestimated or underestimated by 10-15% depending on the calculation algorithm.

• 📉 Urban cycle: actual consumption is 13–16 liters per 100 km.
• 🛣️ Highway cycle: at a speed of 90–100 km/h, consumption remains at 9–10 liters.
• ⚖️ Mixed cycle: on average, owners record 12–13 liters per 100 km.

Factors affecting the appetite of the VQ35DE motor

VQ35DE series engine installed on Nissan Murano Z51, is a reliable and technologically advanced unit, but it does not forgive neglect of maintenance. The main factor determining efficiency, is the state of the ignition and fuel supply system. Worn spark plugs or dirty injectors can increase consumption by 1-2 liters without obvious signs of malfunction.

Particular attention should be paid to the variator control system. The CVT continuously variable transmission only works effectively when the temperature is correct. If the oil in the CVT is old or out of specification, transmission efficiency drops, forcing the engine to work harder. This directly affects fuel consumption.

Driving style plays a critical role in determining the final figure at the gas station. Sharp presses on the gas pedal force the variator to simulate downshifting, spinning the engine to high speeds. Smooth acceleration, on the contrary, allows the system to maintain the minimum required speed, saving fuel.

In addition, the technical condition of the chassis should not be ignored. Stuck calipers or incorrectly adjusted wheel alignment create additional rolling resistance. As a result engine 3.5 spends more energy to overcome these forces, which is instantly reflected in consumption indicators.

• 🔧 Condition of spark plugs: replacement every 40-50 thousand km is mandatory.
• 🌡️ Oil temperature: warming up the engine in winter increases consumption at the start.
• 🚗 Tire pressure: low pressure increases consumption by 5-10%.

Effect of CVT on fuel consumption

The Xtr CVT continuously variable transmission has been designed to optimize engine operation in the most efficient zone. Unlike classic automatic transmissions, the variator allows the engine to operate at optimal speed regardless of the current speed of the car. This should theoretically provide maximum efficiency when driving smoothly.

However, the operation of the variator has its own characteristics that may surprise the driver. When you press the gas sharply, a “rubber band” effect occurs - the engine speed increases sharply, but the speed increases more slowly. At this moment fuel consumption can be critically high, since the ECU supplies the maximum amount of mixture to create force.

To minimize consumption, it is important to understand the logic of the box. In highway driving mode, the variator strives to keep the speed at the lowest possible level. If you feel that the engine is too loud at high speeds, you may need to adjust the gas pedal or check the condition of the variator belt.

⚠️ Attention: Ignoring signals about overheating of the variator or using low-quality CVT fluid can lead to a loss of transmission efficiency and, as a result, to a significant increase in fuel consumption in the future.

There is also a gear shift mode that simulates fixed gears, which is available on some versions. Using this mode on mountainous sections or when overtaking allows you to avoid “floating” revs, which sometimes helps reduce fuel consumption in difficult conditions, although on a flat road this is not always effective.

Seasonal variations and climatic conditions

In winter fuel consumption at Nissan Murano with a 3.5 liter engine naturally increases. This is due to the need to warm up the engine and interior, as well as the use of a heated seat and steering wheel system. In severe frosts, the engine runs on a rich mixture for stable operation, which increases fuel consumption.

Winter tires also play a role. Heavier studded tires or wider winter tires create more rolling resistance. In addition, frequent driving on snowy roads or using snow chains requires more power from the engine, which directly affects the numbers on the display.

In summer, when the air conditioning is turned on, the load on the engine also increases. The air conditioning compressor takes a significant part of the power, especially in start and acceleration modes. In hot weather, when the engine is running at maximum efficiency for cooling, fuel consumption may grow by 0.5–1 liter.

How to properly warm up your Murano in winter?

Despite the fact that modern engines do not require long-term warm-up in place, it is recommended to let the engine run for 2-3 minutes before starting to drive so that the oil is distributed throughout the components. Movement in the first 5-10 minutes should be smooth, without high speeds.

In the off-season, when the roads are often wet, rolling resistance also increases. Drivers should consider these factors when planning long trips and always have extra fuel, especially if you are traveling in unfamiliar areas.

Practical recommendations for reducing consumption

There are a number of proven methods to reduce fuel consumption without compromising the vehicle's dynamics. You should start by checking the technical condition: regularly replacing the air filter, using high-quality fuel additives and timely changing the oil in the engine and variator.

Driving style is a key factor. Avoid sudden starts and braking. Plan your trip in advance to minimize time spent in traffic jams and use the inertia of the car when approaching traffic lights. Smooth control of the gas pedal allows the variator to operate in the most economical mode.

Reducing the load on the vehicle also produces tangible results. Remove unnecessary heavy objects from the trunk and do not use the roof rack unless necessary. Aerodynamics of the crossover Nissan Murano good enough, but additional elements significantly increase air resistance.

Using the correct octane gasoline is also important. Although the 3.5 liter engine is often adapted for 95 gasoline, using 98 or 100 gasoline in some cases can improve combustion and dynamics, but the economic effect will depend on the specific refueling and the quality of the fuel.

Mixed cycle	Miscellaneous	12.0 – 13.5	Monthly average

⚠️ Attention: Fuel consumption above 17 liters in the city during quiet driving indicates a malfunction of the sensors or a problem with the variator and requires immediate diagnosis.

Diagnosis and elimination of causes of high flow

If you notice that fuel consumption exceeds the norm even during quiet driving, it is necessary to carry out diagnostics. The first step is to check the sensors: oxygen sensor (lambda probe), mass air flow sensor (MAF) and throttle position sensor. A malfunction of any of them can lead to incorrect operation of the engine control system.

It is also worth paying attention to the crankcase ventilation system. A clogged PCV valve can lead to increased crankcase pressure and malfunction of the injection system. In such cases, the engine begins to consume more fuel to compensate for the imbalance.

Checking the condition of the spark plugs and ignition coils is mandatory. Misfires lead to incomplete combustion of fuel and loss of power, which forces the driver to press the gas harder, increasing consumption. If the mileage exceeds 100 thousand km, replacement of spark plugs must be carried out without fail.

How to check the lambda probe?

To check the lambda probe, you must use a diagnostic scanner, which will show the sensor voltage in real time. If the voltage does not change or is in the same range, the sensor is faulty and requires replacement.

In some cases, the problem may be hidden in the CVT control system. Errors in transmission adaptation can lead to incorrect shifts and increased consumption. Flashing the software or resetting adaptations often solves this problem.

• 🔍 Diagnostics: scanning for errors via OBDII scanner.
• ⛽ Fuel quality: change the gas station to a proven network.
• 🛠️ Adaptation: reset the variator and throttle settings.

FAQ: Frequently asked questions from owners

Below are answers to the most frequently asked questions regarding fuel consumption. Nissan Murano Z51 with 3.5 engine and CVT.

Is it normal that consumption in the city is 16 liters?

Yes, this is quite normal in winter or during heavy traffic. The 3.5 liter engine has a significant volume, and in conditions of frequent stops its appetite increases. In summer, with quiet driving, this figure should drop to 13–14 liters.

How does the quality of gasoline affect consumption?

Fuel quality directly affects combustion efficiency. The use of low-quality gasoline can lead to detonation, incorrect operation of sensors and, as a result, an increase in fuel consumption by 1–2 liters. It is recommended to refuel at trusted gas stations.

Is it possible to reduce consumption by updating the variator?

There are custom firmwares that change the variator map for an earlier transition to economy mode. However, this may affect the dynamics and resource of the box. Official updates from the dealer are aimed at improving performance, not artificially lowering consumption.

Does wheel size affect fuel consumption?

Yes, installing wheels of larger diameter and width increases rolling resistance and the mass of unsprung elements. This leads to an increase in fuel consumption by 0.5–1 liter per 100 km. It is recommended to stick to standard tire and wheel sizes.

What to do if consumption increases sharply?

First of all, check the tire pressure, condition of the air filter and spark plugs. If these parameters are normal, it is necessary to conduct computer diagnostics to identify errors in the operation of engine or variator sensors.
