Crossover owners Nissan Murano second generation (Z51 body) are often faced with the question: how objective are the gasoline consumption figures declared by the manufacturer? In practice, the situation looks more complicated, since actual consumption depends on many variables, from the condition of the engine to the quality of the road surface. This car, equipped with a powerful V6 engine, requires careful attention to the fuel system.
If you are planning to purchase or already operate this crossover, understanding the real numbers will help you correctly calculate your maintenance budget. Owners note that the difference between the passport data and what the on-board computer shows can be significant. This is especially noticeable in dense city traffic, where the weight of the car and frequent stops play a key role.
Official norms and real statistics
Manufacturer Nissan indicates in the technical documentation rather optimistic figures for a 3.5 liter engine. In the combined cycle, the stated figure is about 10–11 liters per 100 kilometers. However, these data were obtained under ideal laboratory conditions, which are rarely found on our roads. It is important to understand that the aerodynamics of a crossover and its weight affect fuel efficiency.
In real life, especially when driving around the city during rush hours, the numbers increase significantly. Most owners Nissan Murano Z51 Flow rates are recorded in the range of 14–16 liters. On the highway, with a calm driving style, you can meet 9–10 liters, but if you exceed the speed of 120 km/h, consumption increases sharply due to air resistance.
- 🏙️ Urban cycle: 14–17 liters per 100 km
- 🛣️ Highway cycle: 8.5–10.5 liters per 100 km
- 🔄 Combined cycle: 11.5–13.5 liters per 100 km
Impact of driving style on consumption
Engine VQ35DE, installed on the model Murano Z51, very responsive to the gas pedal. An aggressive driving style with sudden starts and stops can increase fuel consumption by 30-40% compared to a smooth ride. The electronic control unit adapts to your habits, but the physics of the process remains unchanged: the more energy spent on acceleration, the more gasoline is burned in the cylinders.
You should pay attention to the operation of the accelerator pedal. Smooth pressing allows the engine to operate in more economical modes. Additionally, using the function Overdrive on the gearbox helps maintain low revs at high speeds, which significantly saves fuel on long trips.
⚠️ Attention! Driving at low rpm for long periods of time with a high load (driving uphill) can be as costly as aggressive acceleration due to the need for forced downshifts.
The engine control system has its own characteristics that must be taken into account. If you are used to constantly “pumping up the gas,” the computer may not have time to adjust the mixture towards leaner, which leads to overconsumption.
- 🚀 Sharp starts increase consumption up to 20 liters per 100 km
- 🐢 Smooth ride reduces consumption to 12 liters
- 🛑 Frequent stops and traffic jams are the main enemy of savings
- 12-13 liters
- 14-15 liters
- 16-17 liters
- More than 18 liters
Technical condition and its role
Condition of technical components Nissan Murano directly affects the efficiency of fuel combustion. Clogged fuel injectors, worn spark plugs or a dirty air filter can cause a significant increase in consumption. Regular maintenance is not just a requirement from the dealer, but a way to protect your budget.
Particular attention should be paid to the state of the system CVT (variator). If the transmission fluid has not been changed for a long time or has signs of overheating, the transmission may not work efficiently, preventing the engine from reaching optimal operating conditions. This causes the engine to run at higher speeds unnecessarily.
| element | Impact on consumption | Recommended frequency |
|---|---|---|
| Spark plugs | High (up to 10%) | Every 30,000–40,000 km |
| Air filter | Average (3–5%) | Every 15,000–20,000 km |
| Fuel injectors | High (up to 15%) | Cleaning every 60,000 km |
| Oxygen sensor (Lambda) | Critical (up to 20%) | Diagnostics in case of errors |
| Tire pressure | Average (2–4%) | Monthly check |
Low tire pressure is also a common cause of overspending. The area of the contact patch with the road increases, which creates additional rolling resistance. Check your pressure before going on a long trip, especially if you are carrying passengers or luggage.
- ✅ Optimal pressure: 2.2–2.4 atmospheres
- ❌ Reduced pressure: increase in flow rate by 5–10%
- 🔧 Regular diagnostics of sensors: mandatory
☑️ Pre-trip checklist
Influence of fuel and refueling quality
For engine VQ35DE The manufacturer recommends using gasoline with an octane rating of at least 95. Using fuel with a lower octane rating can lead to detonation, which the control system tries to compensate for by enriching the mixture. This directly leads to increased consumption and reduced engine life.
The quality of fuel at different gas stations can vary significantly. Even the declared AI-95 sometimes does not meet the standards, which affects the operation of catalysts and lambda probes. Murano Z51 owners often note that switching to trusted gas stations reduces consumption by 0.5–1 liter without changing driving style. Saving on refueling can result in costly repairs to the exhaust system.
⚠️ Attention! Constant use of low-quality fuel can lead to failure of expensive lambda probes and catalytic converters, which will require significant financial investments.
If you notice a sharp jump in consumption, it is worth analyzing which gas station you last refueled at. Sometimes it is enough to change the network station for the situation to return to normal. It is also not recommended to mix fuel from different manufacturers in one tank.
What to do if low-quality fuel is filled?
If you notice a loss of power and increased consumption immediately after refueling, it is recommended to drain the fuel or add special additives to clean the system. As a last resort, contact the service for diagnostics.
Seasonal factors and climatic conditions
Fuel consumption in winter Nissan Murano Z51 naturally increases. This is due to the need to warm up the engine, operate the heater, turn on heated seats and mirrors, as well as the use of winter tires, which have greater rolling resistance. In severe frosts (below -20°C), consumption can increase by 15–20% compared to the summer period.
In hot summer weather there are also nuances. The operation of the air conditioner creates additional load on the engine. If you drive with the windows open at high speed, aerodynamics deteriorate, which also increases consumption. The best option is to use the air conditioner at medium speed, and at low speed, open the windows.
You need to take into account that warming up the engine in winter should not be excessive. Modern engines Nissan ready to move within 2-3 minutes after starting. Prolonged warm-up at idle speed is a pure waste of fuel without benefit to the engine.
- ❄️ Winter period: +2–4 liters to normal
- 🌡️ Air conditioner operation: +0.5–1.5 liters
- 🛣️ Traffic jams with the engine running: significant overrun
Use the Eco Mode function with caution in winter. It makes the gas pedal less sensitive, which can make it difficult to drive on slippery roads when you need to make quick maneuvers.
Methods for reducing fuel consumption
There are a number of proven methods that will help you reduce your gasoline consumption by Murano Z51. First, optimize your driving style: avoid sudden acceleration, keep your distance so you don’t have to brake as often. Secondly, regular maintenance, which we talked about earlier, is the foundation of savings.
It is also worth paying attention to aerodynamics. Remove the roof rails or box when not in constant use. Excess weight on the roof significantly increases air resistance and, as a result, fuel consumption. Remove unnecessary items from the interior and trunk, as every kilogram of weight requires energy to accelerate.
Use the function Stop/Start (if it is available in your configuration) to prevent the engine from idling in traffic jams. This allows you to save up to 5–10% of fuel in the urban cycle. However, in very dense traffic jams with frequent stops, this system may not work correctly, so sometimes it is better to disable it manually.
- 🚫 Remove excess cargo from the trunk
- 🏗️ Remove the roof rack if it is missing
- 🌬️ Keep your windows closed on the highway
The main secret to saving money is not so much technical tricks as it is the smoothness and predictability of your driving.
Features of operation of the CVT variator
CVT Jatco on Murano Z51 has its own characteristics that affect consumption. Unlike classic automatic machines, it strives to maintain optimal engine speed at any speed. However, when you press the gas hard, it can simulate a gear change, accelerating the engine to high speeds, which increases fuel consumption.
To save fuel, it is recommended to use the mode Manual or fixed gears when driving uphill or downhill. This will avoid unnecessary changes in the gear ratio and keep the engine in the high consumption zone. It is also important to monitor the temperature of the CVT, especially in hot weather or when towing.
If you notice that the variator is operating abnormally (vibrations, jerking, kicking), this may be a sign of problems with the valve body or pump. A faulty transmission often means that the engine cannot reach an economical operating mode. Timely oil changes in the variator are critical to its durability and efficiency.
How to properly use the Manual mode on a CVT?
Place the selector in M mode. Use "+" and "-" on the steering wheel or selector to artificially limit the gear. This is useful when overtaking or driving uphill.
Frequently asked questions from owners
Below are answers to the most frequently asked questions regarding fuel consumption. Nissan Murano Z51. If you are experiencing abnormally high consumption, check to see if your situation applies to any of the following.
Why does the on-board computer show such low consumption, but in reality the tank empties faster?
The on-board computer often calculates the average consumption based on the distance traveled and the amount of fuel that was previously filled. If you recently refueled and started driving intensively, the numbers may not be updated in time. The error may also be due to incorrect operation of the fuel level sensor in the tank.
Does oil quality affect fuel consumption?
Yes, the quality and viscosity of motor oil affect the friction inside the engine. Using oil that is too thick, especially in hot climates, or too thin in cold weather, can increase mechanical losses and fuel consumption. It is recommended to use oils with tolerances API SN or higher and viscosity 5W-30 or 5W-40.
What to do if consumption increases sharply after replacing spark plugs?
If consumption increases after replacing the spark plugs, the new spark plugs may have a different glow number or gap that is not suitable for your engine. The cause may also be improper installation or damage to the ignition wires. Check that the spark plugs comply with the manufacturer's recommendations.
Is it normal if the consumption is 18 liters in winter?
For Murano Z51 in severe winter conditions (temperatures below -25°C, short trips, warm-ups), a consumption of 17–19 liters is considered acceptable. However, if you drive mainly on the highway and the consumption is the same, it is worth checking the cooling system and sensors.
Is it possible to reduce consumption by installing gas (LPG)?
Installing LPG (gas equipment) really reduces the cost of mileage, but can slightly increase fuel consumption in liters due to the characteristics of gas combustion. In addition, on a 3.5-liter V6 engine, installing LPG requires careful adjustment so as not to lose power and not harm the ignition system.
