HBO for Nissan Murano: a complete guide to selection, installation and maintenance

Nissan Murano is one of the most popular premium crossovers on the Russian market, combining comfort, power and cross-country ability. However, with rising gasoline prices, many owners are thinking about alternative fuels. Installation of gas equipment (GBO) on Murano allows you to reduce fuel costs by 30-50%, but requires a competent approach: from choosing the generation of gas equipment to professional installation and configuration.

In this article we will analyze all aspects of installing gas equipment on Nissan Murano different generations (Z50, Z51, Z52), including technical nuances, compatibility with engines VQ35DE And QR25DE, as well as real reviews from owners. You will learn which equipment is best to choose for a 3.5-liter V6 or 2.5-liter inline engine, how much installation costs, and how to avoid common operating mistakes.

Which LPG is suitable for Nissan Murano: comparison of generations

The choice of HBO generation depends on the year of manufacture Murano, engine type and budget. Currently there are three options:

• 🔹 HBO 2nd generation - an outdated system with a mechanical metering device, suitable only for carburetor or monoinjection engines. Not relevant for Murano, since all models are equipped with distributed injection.
• 🔹 HBO 4th generation - the most common solution for injection engines. Suitable for Murano Z50 (2003–2007) And Z51 (2008–2014) with motors VQ35DE And QR25DE. Provides a smooth transition from gasoline to gas and back.
• 🔹 HBO 5th and 6th generations — modern systems with liquid phase gas supply (LPG Direct). Optimal for Murano Z52 (2015–present), as they are compatible with direct injection systems and turbo engines. 30-50% more expensive, but more economical and reliable.

For most owners Murano with engine VQ35DE (3.5 l) the optimal choice would be HBO 4th generation from trusted brands: Lovato, BRC, Stag or Digitronic. These systems have proven themselves well on V-shaped engines due to precise calibration of injectors and stable operation under high loads.

But for Murano with motor QR25DE (2.5 l) better to consider HBO 5th generation, as it minimizes power loss and is better adapted to work with variable valve phasing systems (VVT).

Compatibility of LPG with Nissan Murano engines: VQ35DE vs QR25DE

Engines Nissan Murano have fundamental differences in design, which directly affects the selection and configuration of gas equipment. Let's look at the key features:

Parameter	VQ35DE (3.5 L, V6)	QR25DE (2.5 l, R4)
Recommended generation of HBO	4th or 5th	5th or 6th
Loss of power on gas	5–8%	8–12%
Installation Features	Requires 6 injectors, complex routing of lines	More compact, but sensitive to gas quality
Average gas consumption (l/100 km)	12–14	10–12

VQ35DE — a more “gas-resistant” motor due to its robust design and larger displacement. However, his the main disadvantage is the high temperature of the exhaust gases, which requires the installation of a high-quality gearbox with good cooling (for example, Tomasetto Alaska). It is also important to consider that Murano Z50 (until 2007) the ignition system may need to be modified for stable operation on gas.

With motor QR25DE the situation is different: it is more economical, but sensitive to detonation. It is critical to set it up correctly here. ignition timing and use gas with an octane rating of at least 105. Otherwise, the risk of “knuckle knock” increases, especially when driving uphill or with a full load.

⚠️ Attention: On Murano Z51 (2008–2014) with engine VQ35DE When installing a 4th generation gas system, ECU firmware is required to adjust the fuel maps. Without this, “failures” during acceleration and increased gas consumption are possible.

The cost of installing LPG on a Nissan Murano: analysis of prices and configurations

The price of installing HBO at Murano depends on equipment generation, engine type and region. Below is the current price list for 2026 for Moscow and the regions (including work and materials):

• 💰 HBO 4th generation (kit + installation): 65 000–90 000 ₽. Includes reducer, nozzles, cylinder (50–60 l), lines and settings. Suitable for Murano Z50/Z51 with VQ35DE.
• 💰 HBO 5th generation (LPG Direct): 110 000–150 000 ₽. More expensive due to the liquid phase of gas supply, but pays off faster due to fuel savings. Optimal for Murano Z52.
• 💰 Cylinder: toroidal (into the spare tire niche) - 12 000–18 000 ₽, cylindrical (in the trunk) - 8 000–12 000 ₽.
• 💰 Additional work: ECU firmware - 5 000–10 000 ₽, installation of ignition timing variator - 3 000–7 000 ₽.

Average payback period for gas equipment Murano — 1.5–2 years with a mileage of 20,000 km/year. For example, if you drive 1,500 km per month, and the cost difference between gasoline and gas is 20 RUB/liter, the savings will be about 6,000 ₽/month.

It is important to consider that Murano Z52 (since 2015) with the system Direct Injection installation of 4th generation gas equipment is impossible - only 5th or 6th. This is due to the peculiarities of fuel injection directly into the cylinders.

Step-by-step instructions for installing LPG on a Nissan Murano

Installing LPG is a labor-intensive process and requires a professional approach. Below is the sequence of actions for Murano Z51 with engine VQ35DE and 4th generation HBO:

1. Removing the bumper and protection — necessary for laying gas lines and installing a filling device.
2. Installation of the cylinder — the toroidal cylinder is mounted in the spare wheel niche, the cylindrical cylinder is mounted in the trunk with attachment to the body.
3. Gearbox installation — installed under the hood next to the radiator for efficient cooling.
4. Laying highways — gas pipes must be protected from mechanical damage and laid taking into account temperature expansion.
5. Installation of injectors - for VQ35DE 6 pieces are required that cut into the manifold.
6. Connecting electronics — the LPG control unit is connected to the engine ECU via CAN bus or analog signals.
7. Setup and calibration — carried out using diagnostic equipment with adjustment of fuel maps.

Sealing all connections (with soap solution)

Operation of the petrol/gas switch

No errors in the ECU (via scanner)

Gas level in the cylinder (must correspond to the filled volume)

Smooth transition between fuels when driving-->

Pay special attention setting gas pressure in the gearbox. For Murano with VQ35DE optimal value - 1.0–1.2 bar in summer and 1.3–1.5 bar in winter. Incorrect calibration leads to “floating” idle speed or detonation.

⚠️ Attention: After installing the HBO, be sure to register the changes with the traffic police. To do this, you will need a diagnostic card with a mark indicating that the equipment meets the standards. EURO-5 and a technical inspection report.

Operating Nissan Murano on gas: tips and common mistakes

Switching to gas requires changes in driving habits and regular maintenance. Here are key tips for owners Murano:

• ⚙️ Refuel only at proven gas stations — low-quality gas with sulfur or water impurities leads to clogging of injectors and corrosion of the gearbox. Optimal networks: Gazpromneft, Rosneft, Lukoil.
• ⚙️ Warm up the engine before switching to gas - the minimum coolant temperature should be 40–50°C. On a cold engine, gas burns worse, which increases consumption.
• ⚙️ Change filters every 10,000 km - this applies to both the fine gas filter and the vapor phase filter (if any). A clogged filter leads to a drop in power and errors P0300 (misfire).
• ⚙️ Monitor the oil level — gas burns with fewer additives, so the oil loses its properties faster. It is recommended to shorten the replacement interval to 7,000–8,000 km.

One of the most common mistakes is ignoring switching to gasoline at high loads. For example, when overtaking or driving uphill Murano on gas it can become “dull” due to insufficient return. In such cases, it is better to temporarily switch to gasoline by pressing the fuel switch button.

What to do if Murano does not switch to gas?

If after installing LPG the car does not switch to gas, check:

1. Pressure in the cylinder (the multivalve may be empty or faulty).

2. Temperature of the gearbox (should be warm).

3. Presence of errors in the ECU (for example, P0171 - lean mixture).

4. State of the fuse of the HBO control unit (usually 10–15 A).

If the problem is not solved, diagnostics are required at a service station with reading of the gas computer logs.

Another important point - winter operation. At temperatures below –15°C It is recommended to drive the first 5–10 km on gasoline to warm up the gearbox and avoid freezing of the lines. Some owners install gearbox heating from the engine cooling system, which solves the problem.

Owner reviews: pros and cons of LPG on Murano

To form an objective opinion, we analyzed reviews from owners Nissan Murano with HBO on forums Drive2, MuranoClub And GasForum. Here are the key takeaways:

Pros	Cons
Save on fuel up to 50% (at a gas price of 25–30 ₽/liter)	Power loss of 5–10% (especially noticeable on QR25DE)
Increased engine life due to cleaner gas combustion	Additional maintenance costs (filter replacement, leak testing)
Less wear on spark plugs and catalyst	Difficulties with passing inspection due to incorrect registration of gas equipment
Payback in 1.5–2 years with a mileage of 20,000 km/year	Risk of dry starting in winter with a faulty gearbox

Many owners Murano Z51 with VQ35DE note that after installing the 4th generation HBO (BRC Sequent) gas consumption was 12–13 l/100 km against 14–15 l gasoline. At the same time, the acceleration dynamics practically did not change if configured correctly ignition timing.

Among the negative reviews, the most common complaints are about:

• 🔧 Starting problems in winter — can be solved by installing a heated reducer or using winter gas with a high propane content.
• 🔧 Errors appear P0300 (misfire) - usually associated with low gas quality or worn-out spark plugs.
• 🔧 Reducing trunk space - relevant for cylindrical cylinders (toroidal cylinders occupy the spare tire niche).

FAQ: Frequently asked questions about LPG on Nissan Murano

Is it possible to install HBO on a Murano with a CVT?

Yes, CVT Jatco JF011E, installed on Murano, has no restrictions on compatibility with HBO. However, it is important to keep an eye on transmission overheating when driving for a long time on gas under load (for example, uphill). In such cases, it is recommended to temporarily switch to gasoline.

Which cylinder is better to choose: toroidal or cylindrical?

For Murano optimal toroidal balloon (volume 50–60 l), since it fits in the spare wheel niche and does not take up space in the trunk. A cylindrical tank (80-100L) is suitable if you need a long range, but it reduces the usable volume of the trunk by 30-40%.

How much does it cost to re-register an HBO at the traffic police?

The cost of registering gas equipment in 2026 is 1 500–2 500 ₽ (state duty for making changes to the PTS). Additionally, you will need to pay for a diagnostic card (1 000–1 500 ₽) and, if necessary, examination (3 000–5 000 ₽).

Is it possible to drive on gas in winter without problems?

Yes, but subject to the rules:

• Use winter gas (with increased propane content).
• Install gearbox heating (cost ~5,000 ₽).
• For the first 5–10 km after a cold start, drive on gasoline.
• Check the tightness of the lines - in winter the risk of freezing is higher.

At temperatures below –20°C There may be problems with starting, but they can be solved by warming up the engine.

Which LPG is best for Murano Z52 (2015+)?

For Murano Z52 only suitable for direct injection system HBO 5th or 6th generation (For example, Lovato LPG Direct or BRC Xeno). These systems inject liquid gas directly into the cylinders, eliminating power loss and being compatible with Euro-6.
