In the world of SUVs with a name Nissan Patrol There are many legends associated with it, but it is the petrol versions of the car that are of particular interest to collectors and lovers of powerful cars. Unlike diesel counterparts, which are renowned for their efficiency, petrol engines offer a completely different driving experience - smooth, powerful and impressive at high speeds.
Choice in favor gasoline engine often driven by the desire to achieve maximum dynamics without the need for frequent repairs of turbochargers or a complex fuel injection system. However, this power comes at the cost of increased fuel consumption and maintenance specifics, which must be carefully studied before purchasing.
History of the development of gasoline engines for Patrol
The evolution of power units for the legendary SUV began with simple inline sixes, which were installed on the first generations of the model. These motors were distinguished by their incredible simplicity of design and ability to operate in the harshest conditions without critical breakdowns. Over time, engineers moved on to more complex designs, introducing multi-link suspensions and improving the cooling system.
A special place in history is occupied by the transition to V-shaped configurations, which made it possible to significantly increase volume and power without significantly increasing the dimensions of the unit itself. Nissan Patrol The Y61 and Y62 were the first models to be massively equipped with powerful gasoline V8s, which became the standard for the heavy-duty SUV class. This decision allowed the car to feel confident not only off-road, but also on the track.
Modern versions are equipped with direct injection systems and variable valve timing, which makes them more environmentally friendly, but also more demanding on fuel quality. It is important to understand that old naturally aspirated engines and new turbocharged versions require fundamentally different approaches to maintenance.
Characteristics of VK45DE and VK56DE engines
The VK engine series was a real breakthrough for the brand, providing high power and smooth operation. VK45DE, installed on the Y61 and early Y62 models, is a 4.5-liter V8 that is capable of producing up to 300 horsepower. This provides the car with excellent acceleration dynamics, even with a full load and trailer.
Later version VK56DE increased the working volume to 5.6 liters, which made it possible to increase power to 400 hp. and torque up to 560 Nm. Such torque accessible from low revs, which is critical for overcoming difficult off-road conditions without using a reduction gear. The cylinder block is made of aluminum alloy, which reduces weight, but requires careful handling when overheating.
The multipoint fuel injection system and double cam cylinder head (DOHC) ensure efficient mixture formation. However, it should be borne in mind that these engines are equipped with a complex control system that is sensitive to the quality of gasoline. Using fuel with an octane rating below 95 may cause detonation and damage to the piston group.
⚠️ Attention: When operating the VK56DE engine in hot climates, it is necessary to regularly check the condition of the radiator and intercooler, as overheating can lead to deformation of the cylinder head and costly repairs.

Operation and actual fuel consumption
The most important disadvantage atmospheric gasoline in a heavy SUV is an appetite. In the city Nissan Patrol with a V8 engine it can consume from 20 to 25 liters per 100 kilometers. During active off-road driving with all-wheel drive and downshift engaged, this figure can increase to 30 liters or more.
On the highway at a stable speed of about 100 km/h, consumption drops to 16-18 liters, which is still significantly higher than that of diesel analogues. However, owners often note that the comfort and lack of vibrations completely compensate for frequent trips to the gas station. For long journeys, it is recommended to install an additional fuel tank.
In addition, the gasoline engine has the advantage of faster warm-up and no need for long warm-up before driving, which is especially important in winter. Cooling system Patrol designed to effectively dissipate heat even under high loads, but regular checking of the antifreeze level is mandatory.

Reliability and typical problems
Despite the complex design, VK series gasoline engines are considered one of the most reliable in their class. The main problems are not with the cylinder block itself, but with the attachments and the cooling system. Often, owners are faced with failure of water pumps, which require replacement every 100,000 kilometers.
Another common problem is contamination of the throttle body and injectors, which leads to unstable idling. Cooling system also requires attention: plastic pipes become brittle over time and can crack, causing antifreeze to leak. Regular diagnosis allows you to avoid serious consequences.
In the case of engines equipped with a direct injection system, carbon deposits may be observed on the intake valves. This requires periodic cleaning or the use of special additives. If you plan to use the car for a long time, you should pay attention to the quality of the spark plugs, which are changed more often in V8 engines than in in-line six-cylinder engines.
☑️ Check before purchase
⚠️ Attention: If you hear knocking from hydraulic compensators or valves during a cold start, do not ignore it. In Nissan gasoline engines, this may indicate worn camshafts or problems with the oil pump.
Maintenance and replacement of technical fluids
To maintain performance Nissan Patrol With a gasoline engine, you must strictly follow the maintenance regulations. An oil change should be done every 10,000 kilometers, but experienced owners recommend doing this more often - every 7,000 kilometers, especially if the car is used in difficult conditions.
Use only original oil or high-quality analogues with approval API SN/SP and viscosity 5W-30 or 5W-40. Do not forget also about replacing the fuel filter, which is located in the tank in gasoline models and has a limited resource. A clogged filter can cause a drop in fuel pressure and stall the engine.
The cooling system requires replacing antifreeze every 40,000 kilometers. Use only special fluids recommended by the manufacturer, as mixing different types of refrigerants can cause corrosion within the system. Also regularly check the condition of the attachment belts, although on many versions they are replaced by a timing chain, which does not require replacement during its entire service life.
Features of changing oil in the VK56DE engine
When changing the oil in the VK56DE engine, it is important not to forget to replace the filter, which has a specific shape and fastening. It is also worth checking the condition of the oil filter cap gasket, as it often leaks after several oil changes.
- 🛢️ Oil sump volume: 6.3 liters (with filter replacement)
- ⏱️ Replacement interval: every 10,000 km (or 7,000 km for severe conditions)
- 🔧 Oil type: Semi-synthetic or synthetic 5W-30/5W-40
Before changing the oil, warm up the engine to operating temperature so that the old oil drains faster and more completely, taking with it more wear products.
Comparison with diesel analogues
Choice between petrol and diesel engine for Nissan Patrol often becomes a dilemma for buyers. Diesel versions equipped with a motor TD27 or YD25, are significantly more economical and have enormous torque at low revs. However, they are inferior to their gasoline counterparts in terms of smoothness and maximum speed.
The gasoline engine is quieter and smoother, which makes long trips more comfortable. The absence of a turbine and a complex injection system makes the gasoline unit more maintainable in field conditions. Turbine repair A diesel engine can be very expensive, while a gasoline engine only requires regular maintenance.
The table below compares the main characteristics of gasoline and diesel options for clarity:
| Parameter | Gasoline VK56DE | Diesel YD25 |
|---|---|---|
| Power (hp) | 400 | 190 |
| Torque (Nm) | 560 | 450 |
| Fuel consumption (city) | 22-25 l | 12-14 l |
| Engine life | High (during service) | Very tall |
Modifications and tuning
Gasoline engine Nissan Patrol has great potential for tuning. Thanks to the durable cylinder block and reliable connecting rods, the engine can withstand the installation of turbocharging. Compressor kits allow you to increase power to 500-600 hp, turning a heavy SUV into a real racing car.
However, even without major modifications, you can improve the performance by installing a sports exhaust and programmatically reflashing the control unit. This will make the gas pedal more responsive and remove some of the restriction at high revs.
For those who do not want to risk reliability, there are simple improvements: installing zero-resistance air filters and modifying the intake manifold. These measures give a power increase of about 10-15 hp, which is already noticeable when overtaking on the highway. The main thing is not to exceed the permissible engine load without professional analysis.
The VK56DE petrol engine strikes a balance between power and reliability, but requires careful maintenance and quality fuel for long service life.
⚠️ Attention: Installing a turbine on a naturally aspirated engine without replacing the piston group can lead to destruction of the engine at the first serious increase in boost pressure.
