Nissan Murano 3.5 petrol: real fuel consumption and how to reduce it

Nissan Murano with engine 3.5 VQ35DE is one of the most popular crossovers in its class, combining power, comfort and reliability. However, owners are often concerned with the question: which real fuel consumption this car? Official data from the manufacturer often differs from practice, and factors such as driving style, quality of gasoline and technical condition of the car can seriously affect the appetite of the engine.

In this article we will look at fuel consumption standards for Murano different generations (Z50, Z51, Z52), analyze reviews from owners, identify typical causes overspending by 20–30% and give practical advice on how to reduce gasoline consumption without compromising dynamics. We will pay special attention to the nuances of operation in Russian conditions - from the choice of fuel to the characteristics of winter driving.

Official data vs real consumption: what Nissan promises

The manufacturer declares the following fuel consumption figures for Nissan Murano 3.5 (automatic, all-wheel drive):

• 🏙️ City cycle: 12.5–13.8 l/100 km (depending on generation)
• 🛣️ Country cycle: 8.0–8.5 l/100 km
• 🔄 Mixed cycle: 9.5–10.5 l/100 km

However, according to reviews from owners on forums (for example, Drive2 or MuranoClub), real figures are often higher by 15–25%. Thus, in city traffic the consumption often reaches 15–17 l/100 km, and on the highway - 9–11 l/100 km. Why is this happening?

⚠️ Attention: Official consumption tests are carried out under ideal laboratory conditions (temperature +20°C, flat road, minimum load). In reality, the indicators are affected by traffic jams, short trips, the air conditioner on, and even tire pressure.

Generation	Year of manufacture	Official expenditure (mixed)	Real consumption (according to reviews)
Z50 (1st)	2003–2007	10.2 l/100 km	11.5–13.0 l/100 km
Z51 (2nd)	2008–2014	9.8 l/100 km	10.5–12.5 l/100 km
Z52 (3rd)	2015–2021	9.5 l/100 km	10.0–12.0 l/100 km

I wonder what Murano third generation (Z52) despite more modern technologies (for example, the system Eco Mode) does not always show the best results. The point is the increased weight of the body and more stringent environmental standards, which force the engine to operate in less economical modes.

5 main reasons for excessive fuel consumption

If your Murano started to “eat” gasoline beyond the norm, first check these factors:

• 🔧 Clogged injectors or throttle valve. Over time, carbon deposits form on them, disrupting mixture formation. Symptoms: jerky acceleration, unstable idle.
• 🛞 Low tire pressure. Every fall on 0.1 bar increases consumption by 1–1,5%. For Murano optimal pressure: 2.2–2.4 bar (see sticker on the door pillar).
• 🔥 Faulty spark plugs. Worn spark plugs lead to misfires and increased fuel consumption. 5–10%. They need to be changed every 30–40 thousand km.
• 🛢️ Bad fuel. Gasoline with lower octane number AI-95 causes detonation, and the engine VQ35DE automatically adjusts the ignition timing, which leads to overspending.
• 🌡️ Winter operation. It takes up to 1–1.5 liters of fuel per day (at −20°C). Thick oil and heated seats/windows are also affected.

⚠️ Attention: If consumption suddenly increases by 20% or more, check mass air flow sensor (MAF) And lambda probes. Their malfunction leads to a rich mixture and an increase in engine appetite.

How to reduce fuel consumption: 7 working methods

Save gas on Murano 3.5 possible without compromising comfort. Here are proven methods:

1. Use Eco Mode. In the third generation (Z52), this mode responds more softly to the gas pedal and shifts gears earlier, which saves up to 8–10% in the city.
2. Keep an eye on the speed. Optimal range for VQ35DE — 2000–2500 rpm. Accelerate smoothly, avoiding pedal to the metal.
3. Turn off all-wheel drive. On dry asphalt you can drive in 2WD (if there is such an option), this reduces the cost of 3–5%.
4. Change your oil on time. Use synthetics with viscosity 5W-30 or 5W-40 (For example, Mobil 1 ESP or Motul 8100 X-Clean). Dirty oil increases friction and stress on the engine.

Another effective technique is route planning. Avoid traffic jams and short trips (less than 5 km) when the engine does not have time to warm up to operating temperature. For example, three trips of 3 km will consume more fuel than one trip of 10 km.

Comparison with competitors: who is more economical?

How Murano 3.5 does it compare to its analogues? For objectivity, let’s take crossovers with similar engines (3.5–3.6 l, V6) and all-wheel drive:

Model	Engine	Power	Flow (mixed)
Nissan Murano (Z52)	3.5 VQ35DE	260 hp	10.0–12.0 l/100 km
Toyota Highlander	3.5 2GR-FKS	299 hp	10.5–12.5 l/100 km
Honda Pilot	3.5 J35	280 hp	11.0–13.0 l/100 km
Hyundai Santa Fe (3.5 GDI)	3.5 Lambda II	290 hp	11.5–13.5 l/100 km

Murano turns out to be one of the most economical in its class, second only to Toyota Highlander with the system D-4S (direct injection). However, the difference in consumption is often offset by reliability: VQ35DE engine known for its resource (up to 300–400 thousand km with proper maintenance), while Hyundai/Kia with GDI more often suffer from carbon deposits on the valves.

Why is Murano more economical than Santa Fe?

Engine VQ35DE has a more optimal compression ratio (10.3:1 versus 11.5:1 for Hyundai), which reduces the risk of detonation on low-octane fuel. In addition, the variator Nissan (in Z51/Z52) is better adapted for smooth acceleration without jerking, which has a positive effect on fuel consumption.

Winter consumption: how not to go broke on gasoline

In the cold season, fuel consumption is Murano 3.5 can grow by 20–30%. Main reasons:

• ❄️ Long warm-up. Automatic start by timer or alarm “eats” up to 0.5–0.7 l/hour.
• 🔋 Low battery. The generator operates with increased load, increasing consumption by 1–2 l/100 km.
• 🛣️ Snow porridge and ice. Motion resistance increases, and the directional stability system (ESP) more often interferes with management.

To save money, follow these tips:

1. Use preheater (For example, Webasto or Eberspächer). It will reduce warm-up time and reduce fuel consumption 10–15%.
2. Fuel up winter fuel (with antifreeze additives). Gasoline with octane number AI-98 burns more efficiently in the cold.
3. Check condition of the candles. In winter, carbon deposits form on them faster, which impairs the ignition of the mixture.

⚠️ Attention: Do not use cheap anti-gels for gasoline - they can damage the fuel system. It is better to choose proven brands, for example, Liqui Moly Fuel Protect.

Owner reviews: real numbers and life hacks

Owners on forums Murano 3.5 share their experience. Here are some typical examples:

• 👨‍🔧 Alexey, Moscow (Z51, 2010): "In summer, consumption on the highway is 8.5 l/100 km (cruise at 110 km/h). In winter in the city it reaches 16 l. Only preheating saves."
• 👩‍🔧 Maria, Ekaterinburg (Z52, 2017): “After cleaning the throttle and replacing the air filter, the consumption dropped from 14 to 11.5 liters. I recommend checking the throttle position sensor!”
• 👨‍💼 Igor, St. Petersburg (Z50, 2005): “On 92nd gasoline, consumption is 1–1.5 liters higher, but the engine runs softer. On 95th, detonation knocks are sometimes heard.”

General trend: owners Murano the second generation (Z51) note more stable consumption than the first (Z50) or third (Z52). This is due to the optimal combination of weight, power and transmission. Many also advise disable the Start/Stop system (if any), since frequent engine starts in traffic jams only increase consumption.

FAQ: Frequently asked questions about fuel consumption

❓ Which gasoline is better to fill: AI-92, 95 or 98?

Manufacturer recommends AI-95. On AI-92 detonation is possible, especially in hot weather, and AI-98 provides an increase in power (up to 5%), but insignificant savings (0.3–0.5 l/100 km). Optimal choice - 95th from proven gas stations (For example, Lukoil Ecto or Gazpromneft G-Drive).

❓ Why did consumption increase sharply after changing the oil?

The oil may have been filled with unsuitable viscosity (For example, 10W-40 instead of 5W-30). Also check if the oil is fake - low-quality products increase friction. If consumption has not returned to normal after 500 km, flush the engine and change the oil again.

❓ Does tinting affect fuel consumption?

Indirectly - yes. Dark tint makes you use it more often air conditioning or heated seats, which increases the load on the generator. It is estimated that the difference can reach 0.5–1 l/100 km in hot weather.

❓ Is it worth installing HBO on Murano 3.5?

Technically possible, but not recommended. Engine VQ35DE not adapted for gas, which leads to:

• 🔥 Increased wear of valves (there is no lubrication system, like specialized gas engines).
• 📉 Loss of power by 10–15%.
• 💰 Expensive installation (from 80 thousand rubles) and the risk of losing the warranty.

Savings on fuel (gas is 30–40% cheaper than gasoline) are often offset by maintenance costs.

❓ What consumption is considered normal for a Murano with a mileage of 200+ thousand km?

For engine VQ35DE with a mileage of more than 200 thousand km, the following consumption is considered normal:

• 🏙️ City: 13–15 l/100 km (if there are no serious malfunctions).
• 🛣️ Route: 9–10 l/100 km.

If the numbers are higher by 2–3 l, check compression in cylinders, condition of catalysts And variator operation (for Z51/Z52).
