Owners Nissan X-Trail T31 (model years 2007–2013) are often faced with the question: how many liters actually fit into the fuel tank of their car? Official manufacturer data does not always coincide with real indicators, and the difference can reach 5–7 liters. This is especially important for those who plan long trips or want to optimize fuel costs.
In this article we will analyze not only the tank's specifications X-Trail T31, but also real reviews from owners, features of filling under the neck, as well as nuances associated with different types of engines (QR25DE, MR20DE, diesel M9R). You will learn why sometimes it is possible to fill the tank with more fuel than indicated in the documentation, and how this affects the mileage without refueling.
We will also analyze how the tank capacity changes depending on the configuration (for example, with all-wheel drive 4WD or front 2WD), and give practical tips on saving fuel. If you have ever wondered why sometimes 58 or 63 liters fit into the tank at a gas station, here you will find the answer.
Official data: how many liters of tank does the Nissan X-Trail T31 have according to the passport
According to technical documentation Nissan, fuel tank volume for X-Trail T31 (body T31, 2007–2013) is:
- 📄 60 liters - for petrol versions with engines
QR25DE(2.5 l) andMR20DE(2.0 l). - ⛽ 65 liters — for diesel modifications with a motor
M9R(2.0 dCi).
However, these figures often cause controversy among owners. The point is that passport volume indicated taking into account nominal capacity, that is, to the level of the neck, and not until all the internal cavities of the tank are completely filled. In practice, it is often possible to fill a gasoline tank with up to 63–65 liters, and in a diesel engine - up to 68–70 liters.
The difference is explained by the design of the tank: it has a complex shape with stiffening ribs and internal partitions that do not allow fuel to move freely. When refueling to capacity, fuel fills all these cavities, which gives additional liters.
- Gasoline 2.0 (MR20DE)
- Gasoline 2.5 (QR25DE)
- Diesel 2.0 (M9R)
- Other
Real tests: how many liters does the tank hold in practice?
To understand how much fuel actually fits in the tank X-Trail T31, we analyzed reviews from owners on forums (including Drive2, X-Trail Club And Nissan Club Russia). Here's what we found out:
| Engine | Passport volume (l) | Actual volume when filling “before shooting” (l) | Maximum difference (l) |
|---|---|---|---|
MR20DE (2.0 petrol) |
60 | 62–64 | +4 |
QR25DE (2.5 petrol) |
60 | 63–65 | +5 |
M9R (2.0 dCi diesel) |
65 | 68–70 | +5 |
Interestingly, for diesel versions the difference between the rated and actual volume is smaller in percentage terms, but in liters it is the same as for gasoline ones. This is due to the fact that the diesel tank initially has a larger reserve volume.
It is important to consider that refueling "before shooting" (when the gun automatically turns off) does not always mean the tank is completely full. Sometimes after shooting you can add another 1-2 liters, but this risks fuel overflowing through the drainage system, especially in hot weather.
⚠️ Attention: If you regularly refuel "under the neck", monitor the condition adsorber And tank ventilation valve. Overfilling fuel can lead to premature wear.
What determines the actual tank capacity: 5 key factors
The volume of fuel that can be filled into the tank X-Trail T31, depends not only on its design, but also on external conditions. Here are the main factors:
- 🌡️ Ambient temperature. In hot weather, fuel expands and its actual volume increases. For example, at +30°C, 1–1.5 liters less can enter the tank than at +10°C.
- 🔄 Vehicle position. If the machine is parked on a slope (nose up or nose down), the fuel will not be distributed evenly and the level sensor may show inaccurate readings.
- 🛢️ Type of fuel gun.
- 🔧 Condition of the tank ventilation system. clogged ventilation valve or adsorber can create excess pressure, causing fuel to flow more slowly.
- 📉 Remaining fuel before refueling. If there is less than 5 liters left in the tank, the level sensor may be lying and the actual volume of fuel filled will be higher.
It is also worth considering that X-Trail T31 with all-wheel drive (4WD) tank may have a slightly different shape due to the location of the driveshaft. However, the difference usually does not exceed 0.5–1 liter.
If you want to accurately measure the capacity of your tank, fill up "before shooting", then add fuel from the can until it comes out of the neck. The difference will be the real reserve.
How to refuel correctly: tips for maximum mileage
To use the full potential of the fuel tank Nissan X-Trail T31, follow these guidelines:
- Refuel at proven gas stations. Poor quality fuel can lead to the formation of deposits in the tank, which over time reduces its actual volume.
- Do not wait until the reserve light comes on. It is optimal to refuel when there are about 10 liters left. This reduces the risk of sediment entering the fuel system.
- Use fuel with an octane rating of at least 95. For
QR25DEAndMR20DEthis will help avoid detonation and improve efficiency. - Check tire pressure. Flat tires increase fuel consumption by 5–7%, which reduces mileage on one tank.
If you are planning a long trip, keep in mind that actual power reserve depends not only on the volume of the tank, but also on the driving style. For example, when driving on a highway at a speed of 90–110 km/h X-Trail T31 with motor QR25DE can drive to 700–750 km on one tank, while in the urban cycle this figure drops to 450–500 km.

Frequent problems with the X-Trail T31 fuel tank and their solutions
Owners Nissan X-Trail T31 Sometimes they encounter problems related to the fuel system. Here are the most common ones and how to eliminate them:
- ⚡ Incorrect fuel level sensor readings. Most often this is due to oxidation of contacts or wear of the float. Solution: Remove the rear seat, get to the sensor and clean the contacts or replace it.
- 🔥 The smell of gasoline in the cabin. The reason is leaky fuel line connections or cracks in the tank. Solution: inspect the tank on a lift and, if necessary, replace the seals.
- 🛑 Difficulties with refueling (the gun turns off too early). strong> The culprit is clogged ventilation valve or adsorber. Solution: clean the ventilation system or replace the valve.
If you notice that your tank is holding less fuel than before, this could be a sign of deposits or corrosion inside. In such cases, it is recommended to rinse the tank with special compounds (for example, Liqui Moly Tank Reiniger) or contact service.
⚠️ Attention: If after refueling the indicator lights up on the dashboard Check Engine, this may indicate fuel getting into the ventilation system or a malfunction pressure sensor in the tank. In this case, it is better to conduct a diagnosis.
Comparison with competitors: who wins in terms of range?
For objectivity, let’s compare the tank capacity Nissan X-Trail T31 with the main competitors in the class:
| Model | Tank volume (l) | Average consumption (l/100 km) | Cruising range (km) |
|---|---|---|---|
| Nissan X-Trail T31 (2.5 petrol) | 60 (65 real) | 9.5 | 650–700 |
| Toyota RAV4 (2.5 petrol) | 60 | 8.7 | 690 |
| Honda CR-V (2.4 petrol) | 58 | 9.2 | 630 |
| Mitsubishi Outlander (2.4 petrol) | 60 | 9.8 | 610 |
As can be seen from the table, X-Trail T31 It is not much inferior to its competitors in terms of range, and in real conditions, thanks to the possibility of refueling "under the neck", it can even be ahead of them. However Toyota RAV4 benefits from a more economical engine.
Interestingly, the diesel version X-Trail T31 power reserve can reach 900–1000 km, which makes it one of the most “long-range” in the class. For example, Volkswagen Tiguan with a 2.0 TDI diesel engine it has a 64-liter tank, but due to higher consumption (6.5 l/100 km) it is inferior Nissan in mileage at one gas station.
The diesel version of the X-Trail T31 with the M9R engine is the best choice for long trips thanks to its 65-liter tank and low fuel consumption (5.5–6 l/100 km).
FAQ: Answers to frequently asked questions about the Nissan X-Trail T31 tank
Is it possible to fill 92-grade gasoline instead of 95-grade gasoline in the X-Trail T31?
Officially, the manufacturer recommends using fuel with an octane rating of at least 95. However, many owners refuel 92nd no visible problems. Risks: increased engine wear, detonation at high loads, increased fuel consumption by 3–5%. If you decide on the 92nd, monitor the condition of the spark plugs and listen to the engine for any extraneous sounds.
Why does the reserve light come on after refueling "to full" 50 km later?
This is a big problem X-Trail T31associated with a malfunction fuel level sensor or its float. Also the reason may be fuel filter clogged, due to which the fuel pump cannot pump fuel from the far corners of the tank. Solution: diagnostics of the sensor or replacement of the fuel module.
How many liters are left in the tank when the reserve light comes on?
On average, when the light comes on, there is still 7–9 liters. However, this indicator may vary depending on the angle of the vehicle and the health of the sensor. It is not recommended to operate the car “on light bulbs” for more than 50–70 km, as this may lead to sediment getting into the fuel system.
Is it possible to install a larger tank?
Theoretically it is possible, but in practice this requires serious modifications: replacing fuel lines, reconfiguring the fuel level sensor and making changes to the PTS. In addition, an enlarged tank may interfere with elements of the suspension or exhaust system. Most owners prefer to install additional fuel tank (for example, in the trunk) or use cans.
Why does less fuel fit into the tank in winter?
This is due to the physical property of the fuel: at low temperatures it contracts and its density increases. For example, at –20°C, 1–1.5 liters less can enter the tank than at +20°C. Also in winter, gas stations often use “winter” fuel with additives that slightly change its volume.
