The fuel tank is one of the key elements of the car, on which the range and comfort of long trips directly depend. Owners Nissan Qashqai 2019 models are often interested in the exact tank volume in order to correctly plan routes and avoid unpleasant situations on the highway. In this article we will analyze not only the official technical characteristics, but also practical nuances that are important to consider during operation.

The 2019 model, belonging to the second generation (J11), received several engine modifications, which affects fuel consumption and, accordingly, the actual range. We will analyze the data for different configurations, compare them with competitors and give recommendations for optimal refueling. We will pay special attention to the questions that most often arise among owners: why the tank is sometimes “underfilled,” how to correctly measure the remaining fuel, and what to do if the level indicator shows inaccurate data.

Official fuel tank capacity: manufacturer data

According to technical documentation Nissan, fuel tank volume Qashqai 2019 is 55 liters for all modifications, regardless of engine or drive type. This figure has remained unchanged since the 2017 restyling and applies to:

  • 🔹 Gasoline versions: 1.2 DIG-T (115 hp), 1.3 DIG-T (140/160 hp), 1.6 (114 hp)
  • 🔹 Diesel versions: 1.5 dCi (115 hp), 1.6 dCi (130 hp)
  • 🔹 All-wheel drive (4WD) and front-wheel drive (2WD) configuration

It's important to note that the actual filling volume may differ from the rated volume by 2-5 liters downward. This is due to the design of the tank and the fuel level control system, which reserves part of the volume for the safe operation of the fuel pump. Manufacturer indicates full volume, but in practice it is rarely possible to tuck it “under the neck”.

For comparison: the main competitors Qashqai — Toyota RAV4 (55 l), Hyundai Tucson (62 l) and Kia Sportage (62 l) - tank volumes are either comparable or slightly larger. It does Nissan Slightly less durable on long trips, but compensated for by the more economical engines in the range.

Real power reserve: how to calculate and what affects it

Tank volume is only half the information. It is much more important to understand how many kilometers you can travel on one tank. For Qashqai 2019 actual range varies depending on:

  • 🔧 Engine type: diesel versions are 20-30% more economical than gasoline ones
  • 🛣️ Operating conditions: Urban cycle reduces range by 15-20% compared to highway
  • 👨‍🔧 Driving style: Aggressive acceleration increases fuel consumption by 10-15%
  • 🌡️ Seasons: in winter, fuel consumption increases by 5-10% due to heating and use of the stove

Here are approximate data for popular modifications (calculation is based on the mixed WLTP cycle):

Engine Consumption (l/100 km) Cruising range (km) Notes
1.2 DIG-T (115 hp) 5.8 ~950 Optimal for the city, but weak for overtaking on the highway
1.3 DIG-T (140 hp) 6.0 ~915 The best balance of power and efficiency
1.5 dCi (115 hp) 4.5 ~1220 Leader in efficiency, but sensitive to fuel quality
1.6 dCi (130 hp) 4.8 ~1145 Ideal for long trips

These figures are indicative only. For an accurate calculation, use the on-board computer Qashqai, which takes into account individual operating characteristics. To reset statistics and get current data, go to the menu Trip A/B → Reset on the instrument panel.

💡

If you are planning a long trip, refuel before the first shooting of the pistol - this way you are guaranteed to fill 50-52 liters instead of 45-48 during an “automatic” stop.

Why the tank is “underfilled”: common reasons

Many owners Nissan Qashqai are faced with a situation where at a gas station the tank holds less fuel than expected. For example, with an almost empty tank, it is possible to fill only 40-45 liters instead of the stated 55. Reasons for this phenomenon:

  1. Tank design: the reserve compartment (about 5-7 liters) is not available for refueling - it is needed for the operation of the fuel pump.
  2. Sensor inaccuracy: The dashboard may show "empty tank" when in fact there are 3-5 liters left.
  3. Automatic filling nozzle: triggered at the first puff of air, which occurs before it is completely filled.
  4. Vehicle lean angle: When ascending or descending, fuel is redistributed, which affects the sensor readings.

To check the actual fuel remaining, use the "dry tank" method:

Drive until the reserve light comes on (usually with 7-9 liters remaining)

Fill exactly 10 liters from the canister

Drive until the next light comes on and record the distance traveled.

Divide the mileage by 10 - get the real consumption per 1 liter -->

If the difference between the nominal and actual volume exceeds 10 liters, this is a reason to check the tightness of the tank or the functionality of the fuel level sensor. At service centers Nissan Diagnostics of this system will cost 1500-2000 rubles.

What to do if the fuel level sensor is lying?

The most common problem is oxidation of the sensor contacts or its float. In 80% of cases, cleaning or replacing the sensor helps (article number for Qashqai 2019: 17205-4M51A). If the problem is in the electrical circuit, the engine control unit (ECU) will need to be diagnosed.

How to increase your power reserve: practical tips

If the standard tank volume is not enough for you, there are several ways to increase your range without radical modifications:

  • 🛢️ Use fuel additives: additives type Liqui Moly Fuel Protect or Wynn's Diesel System Cleaner improve fuel combustion by 3-5%, which gives +20-30 km of reserve.
  • 🚗 Reduce vehicle weight: Removing unnecessary items from the trunk (for example, 50 kg of cargo) saves up to 0.3 l/100 km.
  • 🛣️ Optimize your route: Avoid traffic jams and short trips - a cold engine consumes 20% more fuel.
  • 🔧 Check your tire pressure: a decrease of 0.2 bar increases the flow rate by 1%. Optimal values for Qashqai: 2.2 bar front and 2.0 rear.

For extreme cases (for example, traveling to remote regions), you can set additional fuel tank. For Qashqai fit models from Longacre or ATS volume of 20-30 liters, which are attached to the trunk. Please note that such a tank requires certification and registration with the traffic police.

Another option - gas cylinder equipment (GBO). Installation of the 4th generation will cost 40-60 thousand rubles, but will pay for itself in 30-40 thousand kilometers. Average gas consumption per Qashqai 1.6 is 7.5 l/100 km, which is 30-40% cheaper than gasoline. The main disadvantage is the loss of space in the trunk (a 50-liter cylinder takes up ~30% of the volume).

💡

The most effective way to save fuel is to maintain a speed of 90-100 km/h on the highway. At this speed, aerodynamic drag is minimal, and the engine operates in optimal mode.

Frequently asked questions about the fuel system Nissan Qashqai 2019

In this section we have collected answers to the most popular questions asked by owners:

⚠️ Attention: If after refueling the knocking sound in the fuel pump or jerks during acceleration, check the fuel quality immediately. In 2019 Nissan recalled the parties Qashqai with defective fuel lines (R1904 campaign), which could crack when using low-quality gasoline.

Is it possible to fill in 92nd gasoline instead of 95th?

Manufacturer recommends AI-95 for all petrol versions. Usage AI-92 allowed in extreme cases, but is fraught with:

  • 🔥 Increased detonation (especially on engines DIG-T)
  • 📉 Power reduction by 5-7%
  • 🛠️ Accelerated wear of the catalyst

If you had to refuel with 92, try not to load the engine (speeds up to 3000 rpm) and dilute the fuel with 95 as soon as possible.

How often should the fuel system be cleaned?

For Qashqai 2019 recommended interval:

  • 🔹 Fuel filter: every 40,000 km (or every 2 years)
  • 🔹 Injectors: flushing every 60,000 km
  • 🔹 Throttle valve: cleaning every 30,000 km

The cost of comprehensive cleaning at the service starts from 3,000 rubles. Suitable products for self-washing BG 44K or Wynn's Injector Cleaner.

Comparison with previous generations and competitors

Tank volume Nissan Qashqai remained unchanged since 2014 (first generation restyling), but other parameters affecting the power reserve changed:

Generation Years Tank volume (l) Average consumption (l/100 km) Cruising range (km)
J10 (1st) 2007-2013 65 7.2 ~900
J11 (2nd, before restyling) 2014-2017 55 6.5 ~845
J11 (2nd, restyling) 2017-2021 55 5.8 ~950
J12 (3rd) 2021-present 55 5.5 ~1000

As can be seen from the table, despite the reduction in tank volume in the second generation, the range has increased due to more economical engines. Among the competitors in 2019 Qashqai occupies middle positions:

  • 🥇 Leaders in tank volume: Toyota RAV4 Hybrid (55 l + electric motor), Skoda Kodiaq (60 l)
  • 🥈 Comparable Models: Mazda CX-5 (56 l), Volkswagen Tiguan (58 l)
  • 🥉 Outsiders: Hyundai Kona (50 l), Kia Seltos (50 l)

Advantage Nissan - in an optimal combination of tank volume and vehicle weight (1300-1500 kg), which has a positive effect on dynamics and handling. For example, Kodiaq with a 60 liter tank it weighs 200-300 kg more, which increases fuel consumption.

Fuel System Maintenance

To ensure that the fuel tank and fuel supply system last a long time, follow the recommendations of the manufacturer and experts:

⚠️ Attention: Never exploit Qashqai with a constantly burning fuel reserve light. This leads to overheating of the fuel pump (article 17040-4M50A, price ~12,000 rubles) and its premature failure. It is optimal to refuel with 1/4 tank remaining.

Basic maintenance procedures for the fuel system:

  1. Replacing the fuel filter:
    • 🔧 For petrol versions: every 60,000 km (the filter is built into the pump, replacement only when assembled)
    • 🛢️ For diesel versions: every 20,000 km (separate filter, article number 16400-JD00B)
  • Cleaning injectors:

    It is carried out using ultrasound or liquid method. Cost - from 2500 rubles. for one nozzle. Signs of contamination: uneven engine operation, increased fuel consumption.

  • Leak test:

    Pay special attention to the fuel line connections and the tank cap. Loss of tightness leads to evaporation of fuel (up to 5 liters per month in hot weather).

    • You can use a scanner to diagnose the fuel system yourself. ELM327 (cost ~1500 rub.) and program Torque Pro. Fuel system related error codes start with P017 (lean mixture) and P018 (problems with the fuel temperature sensor).

    If you plan to park for a long time (more than 3 months), fill the tank to capacity - this will reduce the formation of condensation. Add fuel stabilizer (STP Fuel Stabilizer) at the rate of 1 bottle per 50 liters.

    FAQ: Answers to popular questions

    How many liters does the tank actually hold when filling “to full”?

    When refueling a pistol “before the first shooting,” the tank usually holds 48-52 liters. To fill closer to the passport 55 liters, refuel at low speed (first stage of the pistol) and wait for the second or third “shooting”. Some gas stations (for example, Gazprom Neft) allow you to top up after stopping the gun.

    Is it possible to drive with an almost empty tank?

    Not recommended. In addition to the risk of being left without fuel, this leads to:

    • 🔥 Overheating of the fuel pump (cooled by gasoline)
    • 🧹 Filter clogging with sediment from the bottom of the tank
    • 🛠️ Accelerated corrosion of tank walls (due to condensation)

    It is optimal to maintain the fuel level above 1/4 tank.

    How to reset the on-board computer fuel consumption readings?

    To reset statistics to Qashqai 2019:

    1. Click the button TRIP on the steering column switch
    2. Select Trip A or Trip B (long press)
    3. Hold the button for 3 seconds until the message appears RESET

    To completely reset all data (including average consumption), disconnect the battery for 10 minutes.

    What fuel should I put in diesel versions?

    For engines 1.5 dCi And 1.6 dCi standard fuel recommended EN 590 with a cetane number of at least 51. In winter (below -10°C) use arctic diesel fuel or add antigel (Liqui Moly Diesel Fliess-Fit).

    It is strictly forbidden to mix gasoline with diesel - this leads to failure of the injection system (repair from 80,000 rubles).

    What to do if after refueling the car starts to drive worse?

    Most likely, you refueled with low-quality fuel. Required:

    1. Drain the fuel (at a service center or yourself through a hose)
    2. Rinse the tank with a special liquid (Wynn's Petrol System Cleaner)
    3. Replace the fuel filter
    4. Refuel with quality fuel at a proven gas station

    If the problem persists, run diagnostics for errors. P0300 (misfire) or P0171 (lean mixture).
