Crossover owners Nissan Murano with a 3.5-liter engine are often faced with questions about real gasoline consumption figures. The numbers on the label declared by the manufacturer may differ significantly from what the on-board computer shows in real operating conditions. This is due to many factors, ranging from driving style to the technical condition of the vehicle’s components.
Understanding exactly how the VQ35DE powertrain works will help you predict your fuel costs more accurately and avoid unpleasant surprises at the pump. Real consumption depends not only on traffic jams, but also on the quality of maintenance of the transmission and ignition system. We will look at all the nuances that affect the efficiency of this powerful Japanese crossover.
Features of the VQ35DE engine and its effect on appetite
Engine series VQ from Nissan deservedly considered one of the best in the world, but its characteristic feature has always been high performance at the expense of absolute efficiency. Engine 3.5 l (VQ35DE or its modification VQ35DE V6) is capable of developing impressive power, which inevitably affects the amount of fuel burned.
During sharp accelerations and active driving, the injection system supplies a rich mixture to cool the combustion chamber and prevent detonation. This means that even with a slight increase in speed, fuel consumption can increase sharply. It is important to understand that technical specifications This engine is focused on dynamics, not fuel efficiency.
In urban environments, where it is often necessary to start and accelerate, the engine operates in the most voracious mode. If you prefer a quiet ride, fuel consumption will be closer to average. However, for those who like to "throw" the numbers can be significantly higher.
- 🚗 The VQ35DE engine has high torque, available at low speeds.
- ⛽ The injection injection system reacts to each press of the gas pedal by changing the composition of the mixture.
- ⚙️ The absence of a cylinder shutdown system (in most modifications) maintains a constant high appetite.
Real consumption figures in different driving modes
Owner statistics show that fuel consumption Nissan Murano 3.5 in the city it rarely drops below 14 liters per 100 kilometers. In winter, when warming up and using the stove, this figure easily reaches 17-18 liters. In summer, in conditions of heavy traffic with constant traffic jams, the numbers can vary from 15 to 16.5 liters.
On a suburban highway, when driving at a stable speed of about 90 km/h, the car demonstrates the best results. In this mode, consumption can be 9-10 liters per 100 km. However, if you exceed the speed to 120 km/h and above, the aerodynamic drag will increase and fuel consumption will rise again to 11-12 liters.
The combined cycle is usually around 12-13 liters per 100 km, but these are idealized figures. In reality, if your trip combines city traffic jams and country trips, focus on the average value of 14 liters.
| Riding mode | Speed (km/h) | Consumption (l/100 km) | Note |
|---|---|---|---|
| City (summer) | 0-60 | 14.0 - 15.5 | Average traffic |
| City (winter) | 0-60 | 16.5 - 18.0 | Warming up, stove |
| Route | 90-100 | 9.5 - 10.5 | Uniform stroke |
| Track (high speed) | 120-140 | 11.5 - 12.5 | Aerodynamic drag |
⚠️ Attention: On-board computer readings may underestimate actual consumption by 10-15% due to the peculiarities of calibration of fuel consumption sensors. Always check the numbers using the “full tank” method.
- 12-13 l
- 14-15 l
- 16-17 l
- More than 18 l
Factors critically affecting gasoline consumption
Many owners wonder why their crossover eats more than its neighbor. One of the main reasons is the condition of the ignition and fuel system. Spark plugs that have not been replaced in a long time may misfire, resulting in incomplete fuel combustion and loss of power.
Automatic transmission CVT also plays an important role. If the transmission fluid (CVT fluid) is old or contaminated, the torque converter may not operate efficiently, creating additional slip losses. Regularly changing the oil in the variator is the key not only to durability, but also to reduced consumption.
The air filter is another element that is often ignored. A clogged filter restricts air flow, and the engine control unit is forced to adjust the mixture, which leads to excessive consumption. Check the condition of the filters at each scheduled oil change.
- 🔥 Old spark plugs increase consumption by up to 5-7% due to unstable combustion.
- 🌡️ Operating an air conditioner in hot weather can add another 0.5-1.0 liter per 100 km to your consumption.
- 🚛 Tire pressure below normal increases rolling resistance and engine appetite.
⚠️ Attention: Using poor quality fuel with an octane rating below 95 (or 98 for some versions) can cause detonation and serious damage to the VQ35DE engine.
How to reduce fuel consumption without losing dynamics
There are several proven ways to optimize fuel consumption without sacrificing comfort and safety. First of all, pay attention to your driving style. Smooth acceleration and early engine braking allow you to save a significant amount of gasoline in the city.
Try using coasting mode. In modern models Nissan Murano When the gas pedal is released and the gear is engaged, the fuel supply can be completely shut off (fuel dump mode). This works when you're driving downhill or slowing down before a turn.
Don't forget about aerodynamics. Removable roof racks, when not in use, create additional air resistance and increase fuel consumption on the highway by 1-2 liters. Take them off for long journeys.
☑️ Checklist for reducing consumption
What is Eco mode on Nissan Murano?
When you turn on Eco mode, the throttle valve opens less forcefully even when you press the gas pedal hard. This softens acceleration, but can increase consumption in traffic jams as the engine operates at lower speeds, where efficiency may be lower under hard acceleration.
Influence of time of year and climatic conditions
Winter is a real testing ground for the engine and its efficiency. During the cold season, the air density is higher, and the engine runs on a richer mixture to warm up faster. In addition, the use of heated seats, mirrors and windshield defogger creates additional load on the generator and engine.
The oil in the engine and gearbox becomes more viscous in winter, which increases mechanical losses. This is especially true for CVTs CVT, which require a longer warm-up before starting to move. If you start immediately after starting a cold engine, the consumption will be maximum.
In summer, on the contrary, the main enemy of efficiency is air conditioning. If you use the climate control at full power, the engine must work harder. Try ventilating the interior before turning on the air conditioning to quickly reduce the temperature inside.
- ❄️ Winter consumption can be 20-30% higher than summer due to warming up and air density.
- 🌡️ Using “winter” operating modes of the engine and gearbox helps to adapt to the cold.
- 🔋 The battery at low temperatures requires more energy to start, which also affects consumption.
⚠️ Attention: In severe frosts, it is not recommended to warm up the car at idle for a long time, as this is ineffective and increases consumption. It is better to start driving immediately after the speed stabilizes, but without sudden loads.
To reduce consumption in winter, use an engine preheater or an oil heater. This will reduce the engine idling time when the cabin warms up.
Maintenance for economical driving
Regular maintenance is the foundation of economical operation. The engine control unit (ECU) constantly adapts to the vehicle's condition. If the oxygen sensors (lambda probes) are dirty or do not work correctly, the ECU will not be able to accurately determine the composition of the mixture, which will lead to excessive consumption.
Checking the crankcase ventilation system is also important. A clogged PCV valve can lead to increased crankcase pressure and improper engine operation. This often goes unnoticed by owners until serious problems arise.
For engines 3.5 l It is critically important to monitor the condition of the timing belt (if it is included in the design) or chain. The chain tensioner and guides wear out over time, which can cause variable valve timing and loss of power, forcing the driver to press harder on the gas.
Scheduled replacement of spark plugs and cleaning of the throttle body every 30-40 thousand kilometers is a prerequisite for maintaining low fuel consumption on the VQ35DE engine.
Comparison with competitors and conclusions
Comparing Nissan Murano Compared to other crossovers in the class, it can be noted that its fuel consumption is in the average range. For example, some German competitors with turbocharged engines may show lower consumption in the city, but are inferior in dynamics on the highway. Asian analogues often have similar performance, but differ in transmission design.
Main advantage Murano — это плавность хода и комфорт, которые обеспечиваются именно атмосферным двигателем и вариатором. Платой за это является несколько повышенный расход по сравнению с современными турбомоторами меньшего объема. However, the reliability and service life of the VQ35DE engine often outweigh this disadvantage.
Если вы рассматриваете покупку подержанного экземпляра, обязательно обратите внимание на историю обслуживания. Двигатель, который обслуживался вовремя, будет потреблять меньше топлива, чем аналогичный агрегат с пробегом, но без сервисной книжки.
Why does the consumption on the on-board computer differ from the real one?
Бортовой компьютер рассчитывает расход исходя из длительности впрыска и оборотов двигателя. Он не учитывает потери при холостом ходе в пробках или при прогреве, когда двигатель работает, но автомобиль не движется. Реальный расход считается по методу «залить полный бак, проехать, залить полный бак».
Frequently asked questions (FAQ)
What gasoline is better to fill in Nissan Murano 3.5?
It is recommended to use gasoline with an octane rating of at least 95. For some versions, especially with tuning or in hot climates, the manufacturer allows the use of AI-98 to prevent detonation and increase power.
Why did fuel consumption increase sharply after changing the oil?
This may be due to using oil of the wrong viscosity or quality. It is also possible that during replacement, a sensor was accidentally damaged or the system's seal was broken. Check the oil level and condition of the spark plugs.
Does wheel and tire size affect fuel consumption?
Yes, installing larger diameter wheels and wider tires increases unsprung weight and rolling resistance. This will inevitably lead to an increase in fuel consumption by 1-2 liters per 100 km.
Is it possible to reduce consumption by flashing the ECU?
Reflashing (chip tuning) is most often aimed at increasing power, which leads to the opposite effect - an increase in consumption. There are “eco-firmwares”, but they significantly reduce the dynamics, which makes driving a heavy crossover uncomfortable.
