Economy and actual fuel consumption
The main argument in favor of the diesel version is low fuel consumption. Unlike gasoline counterparts, which can consume up to 15-18 liters per 100 kilometers in the city, diesel Nissan Murano shows much more modest figures. On the highway during quiet driving, consumption can drop to 7-8 liters, which is an excellent indicator for a car of this class and weight.
In the urban cycle the situation is a little different, but it still remains advantageous. Actual consumption varies from 9 to 11 liters depending on driving style and road congestion. Such savings become especially noticeable at high mileage, allowing the owner to significantly reduce the cost of operating the car in the long term.
However, it is worth considering that fuel economy directly depends on the quality of service and driving style. Sudden starts and constant driving at high speeds neutralize the advantages of a diesel engine. In addition, the Brake Energy Recovery system helps further reduce fuel consumption, but it only works effectively if the sensors are working properly.
- 🌍 Environmentally friendly: compliance with Euro-4 and Euro-5 standards reduces restrictions on entry into the centers of large cities.
- 💰 Savings: with a mileage of more than 20,000 km per year, the payback of diesel becomes obvious compared to gasoline.
- 🚀 Traction: High torque allows you to tow trailers and overcome difficult terrain without overheating the engine.
Don't forget about the cost of the fuel itself. Diesel fuel is often cheaper than gasoline, which, combined with lower consumption, provides a double benefit. However, in some regions the price of diesel may be comparable to premium gasoline, which is worth taking into account when calculating.
⚠️ Attention: Do not try to save on fuel quality by refueling at questionable gas stations. The presence of water or mechanical impurities in a diesel engine can instantly damage the expensive common rail injectors.

Typical problems and weaknesses
Despite its overall reliability, diesel Nissan Murano has a number of characteristic weaknesses that a potential buyer needs to be aware of. One of the most common problems is failure turbocharger during prolonged operation at high speeds without proper cooling. Difficulties also often arise with the exhaust gas recirculation system. EGR, which is prone to coking.
Problems with the fuel injection system can manifest as unstable engine idling or loss of power. This is often due to worn injectors or a faulty fuel injection pump. In such cases, professional diagnostics and, possibly, replacement of damaged elements are required. Ignoring the symptoms may result in fuel entering the oil system, which can result in water hammer.
Another weak point is the particulate filter. DPF. When used primarily in urban mode, the filter quickly becomes clogged because it does not have time to go through the regeneration process. This leads to loss of power and increased fuel consumption. In some cases, forced cleaning or even removal of the filter is required, which, however, may lead to problems with environmental certification.
- 🛠️ Turbine: requires regular oil changes and warming up before stopping after a long trip.
- 🔋 Glow plugs: fail at low temperatures, making it difficult to cold start the engine.
- 🚫 EGR valve: requires periodic cleaning of carbon deposits to prevent sensor errors.
Owners also face electrical problems. Pressure, temperature and throttle position sensors may give incorrect readings, causing the engine to go into limp mode. Regular computer diagnostics help identify such problems at an early stage.
Consequences of ignoring problems with the particulate filter
If the DPF is not regenerated or cleaned in time, the filter may become completely clogged. This will result in loss of power, increased fuel consumption and, in the worst case, turbocharger failure due to excess pressure in the exhaust system. Repairs in this case will cost much more.
Features of maintenance and routine maintenance
Compliance with maintenance regulations is the key to a long life of a diesel engine. Nissan Murano. For this engine, it is critical to use only oils recommended by the manufacturer with approval 5W-30 or 5W-40 ACEA C3 class. Saving on oil can lead to rapid wear of the turbine and coking of the channels.
The fuel filter should be replaced more often than specified in the standard regulations, especially if you operate the car in conditions of low fuel quality. It is recommended to change the filter every 15,000 - 20,000 km. It is also worth paying attention to the condition of the fuel lines and connections to avoid leaks.
The cooling system requires special attention. Antifreeze should be replaced at least once every two years, and the fluid level should be checked before each long trip. An overheated diesel engine can cause the cylinder head to warp and the gasket to burn out, which is a serious and costly failure.
☑️ Checklist before buying a diesel Murano
It is also important to monitor the condition of the timing belt or chain (depending on the modification). Although the chain lasts longer, stretching it can lead to poor valve timing. In the case of a belt drive, replacement must be carried out strictly according to regulations, usually every 90,000 - 100,000 km.
⚠️ Attention: It is strictly prohibited to use fuel additives of dubious origin. Many of them can corrode injection system seals or disrupt sensors, leading to failure of expensive components.
Comparison with gasoline analogues
Choosing between diesel and petrol Nissan Murano often depends on operating conditions. Gasoline engines VQ35DE and VQ35HR offer a higher top speed and better dynamics at high speeds, but at the same time consume significantly more fuel. They are also less demanding on fuel quality and easier to maintain in terms of the injection system.
The diesel version wins in efficiency and traction at low speeds. This makes it an ideal choice for those who frequently drive on the highway, tow trailers, or live in harsh climates where high torque is important. However, diesel requires more careful maintenance and more expensive consumables.
The cost of maintaining a petrol variant is usually lower in the short term, but over longer mileage diesel becomes a better deal. It is also worth considering the cost of liquidity during resale: diesel crossovers are often in high demand in the secondary market due to their efficiency.
