Crossover Nissan Murano with 3.5 liter engine VQ35DE - one of the most popular in the line of the Japanese brand, combining power, comfort and off-road capabilities. However, owners are often faced with the question: what kind of real fuel consumption this car? Official data from the manufacturer and reviews from drivers may differ significantly - especially when it comes to the urban cycle or aggressive driving style.

In this article we will look at exact consumption figures for Murano 3.5 (models Z51 and Z52) under different conditions, we will analyze the factors influencing gasoline consumption and give practical advice on how to reduce engine appetite without losing dynamics. We’ll also reveal the myths about “miracle additives” and figure out whether it’s worth switching to 95-grade gasoline instead of 92-grade gasoline.

Official data vs real consumption: where is the truth?

The manufacturer declares for Nissan Murano 3.5 (with automatic transmission) the following fuel consumption indicators:

  • 🏙️ Urban cycle: 12.5–13.8 l/100 km
  • 🛣️ Country cycle: 8.5–9.2 l/100 km
  • 🔄 Mixed cycle: 10.2–11.0 l/100 km

But owners on forums and reviews often report numbers on 15–25% higher. Why is this happening? The fact is that factory tests are carried out under ideal conditions: on a flat road, at optimal temperature, with minimal load and with fresh oil. In reality, consumption is affected by:

  • 🚦 Frequent acceleration and braking (especially in traffic jams)
  • 🧊 Cold climate and long engine warm-up
  • 🔧 Condition of the air filter, spark plugs and fuel system
  • 🎒 Car load (roof rack, trailer)
  • 🛞 Tire pressure and rubber type
📊 What is your actual fuel consumption for the Nissan Murano 3.5?
  • Up to 12 l/100 km
  • 12–14 l/100 km
  • 14–16 l/100 km
  • More than 16 l/100 km

Based on independent tests (including ADAC And Consumer Reports), average consumption Murano 3.5 in a mixed cycle is 11.5–13.5 l/100 km. However, in winter these numbers can increase to 15–17 l/100 km - especially if the car is equipped with all-wheel drive ATTESA E-TS and is operated in mode 4WD Lock.

Factors affecting fuel consumption: what can be corrected?

Some causes of increased consumption cannot be eliminated (for example, climatic conditions), but most depend on technical condition of the car And driving style. Let's look at the key points:

1. Condition of the engine and systems

  • 🔥 Clogged air filter increases consumption by 5–10%. It needs to be changed every 15–20 thousand km (or more often when driving on dusty roads).
  • ⚡ Faulty spark plugs lead to misfires and excessive fuel consumption. For VQ35DE candles recommended NGK PLFR5A-11 or Denso FK16HR11.
  • 🛢️ Dirty injectors disrupt fuel atomization. Cleaning with ultrasound or special additives (for example, Liqui Moly Injection Reiniger) can reduce consumption by 1–2 l/100 km.

2. Transmission and chassis

  • 🔄 Worn clutch (for manual transmission) or faulty automatic transmission (RE5R05A) can increase consumption by 10–15%.
  • 🛞 Low tire pressure increases rolling resistance. Optimal pressure for Murano 3.5: 2.2–2.4 bar (check once a month!).
  • 🔧 Unadjusted wheel alignment angles lead to uneven tire wear and increased consumption.

3. Driving style and load

Aggressive acceleration, braking and driving at high speeds (higher 3000 rpm) increase consumption by 20–30%. Optimal mode for VQ35DE — 1800–2500 rpm at speed 80–100 km/h.

⚠️ Attention: Using the mode Sport on automatic transmission increases consumption by 10–15% due to later gear changes and higher speeds.

Comparison of consumption by generation: Z51 vs Z52

Nissan Murano 3.5 produced in two generations: Z51 (2003–2007) And Z52 (2008–2014). Despite the same engine size, their fuel consumption is different due to changes in the transmission and aerodynamics.

Parameter Murano Z51 (2003–2007) Murano Z52 (2008–2014)
Engine VQ35DE (245 hp) VQ35DE (265 hp)
Transmission Automatic transmission RE5R05A (5 tbsp.) Automatic transmission RE5R05A (5 tbsp.) or CVT JF011E (since 2011)
Consumption in the city (l/100 km) 13.0–15.0 12.5–14.5 (automatic transmission) / 12.0–14.0 (CVT)
Consumption on the highway (l/100 km) 9.0–10.5 8.5–9.5 (automatic transmission) / 8.0–9.0 (CVT)
Notes More “gluttonous” due to outdated ECU firmware Better aerodynamics and optimized software

Models with variator (CVT) turned out to be more economical than a classic automatic transmission 0.5–1.0 l/100 km, but only during quiet driving. In the "gas to the floor" mode, the variator loses in dynamics and can even exceed the consumption of the automatic transmission.

💡

If you have Murano Z51 with a mileage of more than 150 thousand km, check the condition of the catalysts - their clogging can increase consumption by up to 18–20 l/100 km!

How to reduce fuel consumption: practical tips

Even without deep tuning you can reduce your appetite Nissan Murano 3.5 on 10–15%. Here are proven methods:

1. Optimizing your driving style

  • 🚗 Use cruise control on the highway - this reduces fuel consumption 5–7% due to smooth speed maintenance.
  • 🛑 Avoid long warm-up at idle. Enough 30–60 seconds in summer and 1–2 minutes in winter, after which you can start driving at low speeds.
  • 🔄 Switch to a higher gear as early as possible (for manual transmission) or avoid the mode Sport (for automatic transmission/CVT).

2. Maintenance

  • 🛠️ Regularly (every 10 thousand km) check tire pressure - lack of everything 0.3 bar increases consumption by 1–1.5 l/100 km.
  • 🔧 Change engine oil every 7–8 thousand km (even if the manufacturer recommends 15 thousand). For VQ35DE optimal oil 5W-30 or 5W-40 with permission API SN.
  • 🔥 Clean throttle valve every 30–40 thousand km — its contamination leads to unstable engine operation and excessive consumption.

3. Fuel and additives

Many owners argue: 92 or 95 gasoline better for Murano 3.5? According to the passport, the engine is designed for AI-92, but the transition to AI-95 can give:

  • ⛽ Slight reduction in consumption (on 0.3–0.5 l/100 km) due to the better octane number.
  • 🔥 More smooth engine operation, especially at high speeds.
  • ⚠️ But! If the engine is not adapted for the 95th (there is no firmware for Euro 4/5), the effect will be minimal.
⚠️ Attention: Additives type "Suprotek" or "EDIAL" can give a temporary effect (reducing consumption for 0.5–1 l/100 km), but do not replace high-quality maintenance. Some additives (especially those with aggressive solvents) can damage the fuel system!
💡

The most effective way to reduce consumption is a combination of a smooth ride, timely maintenance and high-quality fuel. No “miracle cure” can replace these three factors.

Frequent mistakes by owners leading to excessive fuel consumption

Many drivers Nissan Murano 3.5 Without knowing it, they take actions that increase gasoline consumption. Let's look at the top 5 mistakes:

1. Ignoring the "Check Engine" signal

Even if the car "drives normally", a lit light may indicate:

  • 🔧 Misfires (consumption +10–15%)
  • 🛢️ Faulty oxygen sensor (flow +5–20%)
  • 🔥 Problems with the catalyst (consumption +20–30%)

You can carry out diagnostics yourself using a scanner. ELM327 (cost ~1500 rub.) or contact a service station.

2. Use of non-standard wheels

Installation of wheels and tires with parameters different from those recommended (235/65 R18 or 235/55 R20), increases rolling resistance. For example, tires 245/50 R20 can add up to 0.5–1 l/100 km.

3. Constant driving with all-wheel drive on

Mode 4WD Lock or AWD Auto useful off-road, but in the city it increases fuel consumption 10–15%. Use 2WD on dry asphalt!

4. Vehicle overload

Every 100 kg additional weight (luggage, trailer) increase consumption by 0.5–0.8 l/100 km. Remove the roof rack when not in use.

5. Neglect of wheel alignment

Incorrect wheel alignment angles not only eat up rubber, but also increase driving resistance, adding 0.5–1 l/100 km.

What to do if consumption suddenly increases by 20–30%?

If fuel consumption increases sharply (for example, from 12 to 16 l/100 km), check:

1. **Fuel leaks** (the smell of gasoline under the hood or under the car).

2. **Fuel pump malfunction** (roar from the gas tank, jerking during acceleration).

3. **Air leak** in the manifold (crackling or hissing under the hood).

4. **Clogged catalyst** (power loss, black smoke from the exhaust).

In such cases, urgent diagnosis is required!

Owner reviews: real consumption figures

To give an objective picture, we analyzed reviews from owners Nissan Murano 3.5 on the forums (Drive2, Nissan-Club, Auto.ru). Here are typical indicators:

Driving conditions Minimum consumption (l/100 km) Average consumption (l/100 km) Maximum consumption (l/100 km)
City (traffic) 13.0 14.5–16.0 18.0–20.0 (winter)
Route (90–110 km/h) 8.0 8.5–9.5 10.5 (with trailer)
Mixed cycle 10.5 11.5–13.0 14.0–15.0
Off-road (sand, mud) 15.0 16.0–18.0 20.0+

Interesting observations from the owners:

  • 🔋 After replacement battery to a more powerful one (for example, Bosch S5 95Ah) some noted a decrease in consumption 0.3–0.5 l/100 km due to the stable operation of electronics.
  • 🛠️ Cleaning throttle valve and adaptation ETCS (electronic throttle) often gives an effect in –0.5 l/100 km.
  • ❄️ In the cold (–20°C) consumption can reach 20 l/100 km due to prolonged heating and thick oil.

FAQ: Answers to frequently asked questions about fuel consumption

❓ Why is my consumption 18 l/100 km, although everyone is talking about 12–14?

Probable reasons:

  • 🔧 Clogged injectors or air filter.
  • 🛢️ Faulty spark plugs or high-voltage wires.
  • 🚗 Aggressive driving style with frequent accelerations up to 4000+ rpm.
  • 🔥 Winter operation with long-term heating.
  • 🛞 Non-standard wheels or low tire pressure.

Check first oxygen sensor And catalysts — their malfunction most often leads to such overspending.

❓ Is it worth switching to gas (LPG) for Murano 3.5?

Installing HBO on VQ35DE possible, but has some caveats:

  • ✅ Pros: savings up to 40% on fuel (at a gas price of ~25 rubles/liter vs 50 rubles/liter for 95-grade gasoline).
  • ❌ Cons:
    • Power reduction by 5–10%.
    • Risk valve overheating (the engine is not designed for gas).
    • Difficulties with registration of HBO at the traffic police department.
    • Expensive maintenance (replacement of gearbox and filters every 15–20 thousand km).

Conclusion: HBO will pay off only if the mileage is from 30 thousand km/year. For rare use, it is better to stay on gasoline.

❓ What kind of gasoline should I use: 92 or 95?

Officially Nissan Murano 3.5 designed for AI-92, but:

  • 🔥 On 95 gasoline the engine runs smoother, especially at high speeds.
  • ⛽ Consumption may decrease by 0.2–0.5 l/100 km, but only if the engine is adapted (firmware for Euro-4/5).
  • ⚠️ On older engines (before 2008) with a low compression ratio (10.3:1) there is almost no difference.

Recommendation: if there is no detonation on the 92, you can stay on it. If you hear “ringing” when accelerating, go to 95th.

❓ Do additives help reduce consumption?

Effect of additives (Liqui Moly, Wynn's, Hi-Gear) is temporary and depends on the condition of the engine:

  • ✅ They can help if:
    • The injectors or intake tract are dirty.
    • The engine has mileage up to 150 thousand km.
  • ❌ They won’t help if:
    • The problem is mechanical (worn rings, valves).
    • Catalysts are clogged.
    • Cheap additives with abrasives are used.

Better to spend money on ultrasonic cleaning of injectors (cost ~3000 rub.) or replacement of consumables.

❓ Is it possible to reduce consumption by chip tuning?

Chip tuning for VQ35DE can:

  • ✅ Increase power by 10–15 hp and torque.
  • ✅ Optimize fuel consumption on the highway (reduce by 0.3–0.7 l/100 km).
  • ❌ But! In the city, consumption may increase due to sharper throttle settings.

Firmware cost: 15–25 thousand rubles.. Justified only for lovers of dynamic driving.
