The question is how many liters does the gas tank hold? Nissan Terrano, occurs among owners of this crossover in a variety of situations: from planning long trips to diagnosing fuel system faults. Despite its apparent simplicity, the topic has many nuances - from differences between generations R50, R51 And R20 to the specifics of measuring the remaining fuel in the tank. In this article we have collected current data from official Nissan sources, as well as practical observations from car owners, which will help to avoid errors during refueling and operation.

Many drivers encounter discrepancies between the rated values and the actual volume of fuel being filled. For example, why is it that when the tank is “empty” it is sometimes possible to fill 5-7 liters more than indicated in the instructions? Or why does the on-board computer show 10 liters remaining, but the gas station shows 50? The answers to these questions lie in the design of the fuel system, the characteristics of the sensors, and even the climatic conditions. Next, let's look at everything in order.

Official data: gas tank volume by generation

Manufacturer Nissan indicates the volume of the fuel tank in the technical documentation for each modification Terrano. However, these figures often raise questions among car owners, since they do not take into account the “reserve” volume and features of the shape of the tank. Below is a table with official data for all generations produced in the Russian and European markets.

Generation Years of manufacture Tank volume (liters) Fuel type Notes
R20 (1st generation) 1986–2006 60 Gasoline AI-92/95 For European and Japanese markets. In some modifications - 65 liters.
R50 (2nd generation, Renault-Nissan) 2014–2020 50 Gasoline AI-95, Diesel For petrol versions. Diesel models - 55 l.
R51 (R50 facelift) 2020–2023 50 (petrol) / 55 (diesel) Gasoline AI-95, Diesel No changes compared to R50. In some countries - 52 l.
R50/R51 (special versions) 2016–2023 58 Gasoline AI-95 For markets in the Middle East and Africa (larger tank).

It is important to understand that these values are nominal volume, which does not take into account:

  • 🔹 Reserve volume (usually 5-7 liters, inaccessible for draining through the standard neck).
  • 🔹 Tank shape: in Terrano R50/R51 it has a complex geometry with “pockets” where fuel can remain even when the reserve light is on.
  • 🔹 Sensor error: On an inclined surface (for example, on a hill), the readings may be distorted by ±3-5 liters.
⚠️ Attention: If, when filling “to full,” the tank holds 10+ liters more than the rated volume, this may indicate a malfunction of the ventilation valve or deformation of the tank. In this case, diagnostics at a service station is required.

Why does the actual filling volume differ from the rated volume?

One of the most frequently asked questions from owners Nissan Terrano: “Why does an empty tank hold 55 liters, if according to the passport it holds 50?” There are several reasons, and not all of them are related to malfunctions.

Firstly, the manufacturer indicates usable volume — the amount of fuel that can be poured through the standard filler neck without the risk of overflow. However, in reality:

  • 🛢️ "Reserve" after the light comes on, it is ~5-7 liters (depending on the generation).
  • 🛢️ Tank geometry allows you to fill an additional 3-5 liters after the first shooting of the pistol at a gas station (if you add it slowly).
  • 🛢️ Temperature expansion: When refueling in hot weather, the fuel expands, and after cooling, its level drops.

Secondly, at stations with high filling rates, automatic nozzles may turn off before the tank is completely filled. In such cases it helps manual topping (but without fanaticism - overfilling can damage the adsorber!).

📊 How often do you refuel your Terrano “to full”?
  • Whenever the light comes on
  • Only before long trips
  • Every second refueling
  • Never, I pour a fixed amount

How to correctly measure the remaining fuel?

Many drivers Terrano are faced with the fact that the on-board computer shows the remaining fuel inaccurately. This is especially noticeable on R50/R51, where the fuel level sensor has a nonlinear characteristic. To avoid mistakes, follow these guidelines:

  1. 📏 Use the fuel dipstick (if there is access to the tank). On Terrano R20 it's easier than on newer models.
  2. 📏 Reset BC readings after each refueling "until full". To do this:
1. Заправьтесь до первого отстрела пистолета.

2. Заведите автомобиль.


3. Нажмите и удерживайте кнопку сброса суточного пробега (на приборной панели) в течение 5 секунд.

On Terrano R50/R51 with the system NissanConnect you can use an alternative method:

  • 🔧 Go to Settings → Fuel → Sensor Calibration.
  • 🔧 Select an option "Reset after refueling".
⚠️ Attention: If, after resetting, the BC shows a consumption of more than 15 l/100 km on the highway (at a speed of 90-110 km/h), this may indicate a fuel leak or a malfunction of the injectors. Check the tightness of the fuel lines!

Features of the gas tank in diesel versions of Terrano

Diesel modifications Nissan Terrano R50/R51 equipped with a tank capacity 55 liters (versus 50 for gasoline ones). This is due to:

  • 🔋 High specific consumption diesel fuel (on average 10-15% higher than gasoline analogues).
  • 🔋 Fuel system design: The diesel tank has additional sections for settling water and paraffin deposits.
  • 🔋 Range requirements: Diesel versions are often used for towing or off-road use.

Diesel owners Terrano it's important to remember winter fuel:

  • 🌡️ At temperatures below –15°C it is recommended to use arctic diesel fuel or add antigel.
  • 🌡️ There should always be at least ¼ volume - this reduces the risk of condensation and corrosion.
What to do if the diesel engine is frozen?

If there is fuel in the tank Terrano thickened, do not try to start the car “forcibly” - this may damage the fuel injection pump. Optimal algorithm:

1. Tow the car to a warm box.

2. Add a defroster to the tank (for example, LIQUI MOLY Diesel Fliess-Fit).

3. Warm up the tank with a hair dryer (do not direct the flow at the level sensor!).

4. After thawing, drain the sediment through the plug at the bottom of the tank.

Common gas tank problems and their solutions

Owners Nissan Terrano Often encounter problems related to the fuel system. Here are the most common ones and how to eliminate them:

Problem Reason Solution
Reserve light comes on too early Faulty level sensor or float Replacing the sensor (article number for R50: 25060-JM00A)
When refueling, fuel "splashes" back Ventilation valve clogged Cleaning or replacing the valve (located under the rear right fender)
Extraneous noise (gurgling) from the tank Air pockets or damage to the fuel pump Pump diagnostics (for R51 - art. 17040-JM01A)
Fuel leak under the car Crack in the tank or damage to the fuel line Visual inspection, replacement of damaged elements

Particular attention should be paid tank corrosion - the problem is relevant for Terrano R20 over 15 years old. Signs:

  • 🔍 Rusty leaks under the tank.
  • 🔍 The smell of gasoline in the cabin (through the ventilation ducts).
  • 🔍 Pressure drop in the system (error P0455 on diagnostics).
⚠️ Attention: If on Terrano R50/R51 An error appeared after refueling P0420 (low catalyst efficiency), this may be due to poor quality fuel. Do not ignore it - long-term driving with this error leads to failure of the lambda probes (replacement cost - from 8,000 rubles per piece).
💡

When refueling at unfamiliar gas stations, always check the receipts: if the octane number of the fuel is lower than stated (for example, AI-92 was filled instead of AI-95), this can lead to detonation and damage to the piston group. B Terrano R51 with engine HR16DE It is especially critical to use fuel not lower than AI-95.

Modifications with an enlarged gas tank: myth or reality?

On owner forums Nissan Terrano Methods to increase the volume of the fuel tank are periodically discussed. Let's look at what is real and what is not.

Option 1: Installing a tank from another model

  • ✅ From Nissan X-Trail T31 (60 l) - theoretically possible, but requires modification of fastenings and fuel lines. The cost of work exceeds 20,000 rubles.
  • ❌ From Patrol Y61 (95 l) - incompatible in size and ventilation system.

Option 2: Additional tank

  • ✅ Installation external tank (for example, from Toyota Land Cruiser 70) in the trunk. Legal only for off-road modifications.
  • ⚠️ Requires re-registration with the traffic police as a design change.

Option 3: Fuel cans

  • ✅ The easiest and most legal way. For Terrano canisters fit 20 l with the system Jerry Can (for example, from RotopaX).
  • ⚠️ You can store no more than 60 liters of fuel in the cabin (according to traffic regulations).
💡

Any modifications to the fuel system Nissan Terrano require approval from the traffic police. Unauthorized changes may result in refusal of technical inspection or cancellation of insurance in case of an accident.

FAQ: Answers to popular questions

How many liters can be filled into the Terrano R50 after the reserve light comes on?

On average - 7-9 liters. However, this depends on your driving style and the grade of the road. For example, when driving uphill, the remaining fuel may “collect” in one corner of the tank, and the sensor will show a false reserve ahead of time. For accuracy, use the test refueling method: after the light comes on, refuel until full and write down the number of liters.

Is it possible to drive with an almost empty tank?

Not recommended. B Terrano R50/R51 The fuel pump is cooled by gasoline, and at a level below 10 liters it runs dry, which reduces its service life. In addition, mechanical impurities accumulate in the sediment at the bottom of the tank, which can clog the filter. It is optimal to maintain a level not lower than ¼ tank.

Why does the volume of refueled fuel decrease in cold weather?

This is due to thermal compression of fuel. Gasoline at –20°C decreases in volume by ~1.5% compared to +20°C. For example, if in summer the tank holds 50 liters, in winter it could be 49-49.5 liters. Diesel is compressed even more - up to 2-3%. Also, in cold weather, gas stations can use the “winter” setting of the guns, which limits the filling speed.

What kind of gas should I put in the 2020 Terrano R51?

For petrol versions Terrano R51 with engines HR16DE And MR20DD manufacturer recommends AI-95. The use of AI-92 is allowed only in emergency cases and is fraught with:

  • 🔥 Increased detonation (especially when towing).
  • 🔥 Early wear of the catalyst.
  • 🔥 Power loss up to 5-7%.

For diesel versions (K9K) - only DT EURO-5 with a cetane number of at least 51.

Where is the fuel pump fuse located in Terrano R50?

Pump fuse (15A) is located in interior mounting block (under the dash on the driver's side). To access:

  1. Open the driver's door.
  2. Remove the fuse box cover (press the latch in the upper left corner).
  3. Look for a fuse marked F30 (for models up to 2018) or F27 (after 2018).

Also check the pump relay (R12), if fuel is not supplied when the ignition is turned on.
