Nissan Cefiro: fuel tank capacity by generation (A31, A32, A33)

Car Nissan Cefiro - a legendary business class model, produced from 1988 to 2003. During this time, there were three generations (A31, A32, A33), each of which had its own design features, including the capacity of the fuel tank. Owners and potential buyers are often interested in: How many liters does the Cefiro tank hold? The answer depends on the modification, year of manufacture and market - Japanese, European and American versions could differ.

In this article we will look at exact tank volumes for all generations Nissan Cefiro, we will explain how to correctly measure the fuel level, and warn against common mistakes when refueling. You will also learn why the actual capacity may differ from the rated capacity, and how this affects the power reserve. If you are planning a long trip or just want to understand the technical nuances, read on.

Nissan Cefiro tank volume by generation (official data)

Manufacturer Nissan indicated different fuel tank capacities depending on generation and market. Below is a summary list passport details for basic modifications:

Generation	Years of manufacture	Tank volume (liters)	Notes
Nissan Cefiro A31	1988–1994	65–70	Depends on the configuration. Japanese versions often had 65 liters, export ones - up to 70 liters.
Nissan Cefiro A32	1994–1998	70	Standard for most markets. There are modifications with a 72 liter tank (rare).
Nissan Cefiro A33	1998–2003	70–75	Basic version - 70 l. All-wheel drive and some export models could have 75 hp.

It is important to consider that real capacity may be 5–10% less than the nameplate due to the design of the tank (for example, due to internal partitions or a level sensor). In addition, in some countries the manufacturer underestimated official figures to reduce taxes. For example, in Japan Cefiro A31 often specified with a 65 liter tank, although it physically held up to 68–70 liters.

To accurately determine the tank capacity of your model, check sticker on the gas tank flap or technical documentation. If the documentation is lost, you can rely on the VIN code - the dealer or service center will use it to tell you the exact specifications.

Why can the actual volume of the tank differ from the rated volume?

Many owners Nissan Cefiro are faced with a situation where, when refueling “under the neck,” the tank holds less fuel than indicated in the technical specifications. There are several reasons:

• 🔧 Tank design: internal partitions (to prevent splashes) reduce the usable volume. For example, in Cefiro A32 ~65 liters out of 70 liters are actually available.
• ⚖️ Level sensor inaccuracies: The dashboard may display an “empty tank” when in fact there are 5-8 liters left.
• 🌡️ Temperature expansion: When refueling in hot weather, the fuel expands and after cooling the level drops.
• 🔄 Residues in the fuel system: after draining the gasoline, 1–2 liters remain in the lines, which are not taken into account.

Critical nuance: in tanks Nissan Cefiro A33 with an all-wheel drive (4WD) system, an additional compartment for the fuel pump was often installed, which reduced the useful volume by 3–5 liters. If you refuel “before shooting” the pistol, keep in mind that there may be a “dead” supply of fuel in the tank that is inaccessible to the pump.

To check the actual capacity, carry out an experiment: completely fill the tank on a column with liters fixed, then drain the fuel into a canister and measure the volume. The difference between the filled and drained amount will show the “hidden” reserve.

How to properly refuel Nissan Cefiro: tips and warnings

Improper refueling can lead to fuel overflow, damage to the canister, or even fire. Follow these rules:

1. Do not refuel “before shooting” the gun at old gas stations - the automation may work with a delay, and gasoline will pour onto the body.
2. Use fuel with an octane rating of at least 92 (for Cefiro A31/A32) or 95 (for A33). AI-90 gasoline is not recommended - this will lead to detonation and accelerated engine wear.
3. Refuel at trusted gas stations - low-quality fuel clogs fuel filters, especially in models with an injection system.
4. Don't leave the tank empty for too long - this leads to corrosion of the internal walls and failure of the fuel pump.

⚠️ Attention: B Nissan Cefiro A33 with engine VQ25DD (2.5 l) when refueling to capacity, the gasoline vapor recovery system (EVAP) may be triggered, which leads to an error P0440 or P0446. To avoid this, leave 5-7% free space in the tank.

If you often drive long distances, fill up to 80-90% of the full volume - this will reduce the load on the fuel pump and reduce the risk of overfilling when gasoline heats up. To control consumption, use the on-board computer (if available) or mobile applications like Fuelio or Car diary.

Nissan Cefiro range: how long can you drive on one tank?

Power reserve depends on tank volume, engine type And driving style. Below is an approximate table for different modifications for a mixed cycle (city/highway 50/50):

Model	Engine	Tank volume (l)	Consumption (l/100 km)	Cruising range (km)
Cefiro A31	2.0 RB20E	65	9.5–11	590–680
Cefiro A32	2.5 VQ25DE	70	10–12	580–700
Cefiro A33	3.0 VQ30DD	75	11–13	570–680

On the highway at a speed of 90–110 km/h, consumption is reduced by 15–20%, which increases the range to 700–800 km. In a city with frequent traffic jams, the actual mileage on one tank can be reduced to 450–500 km. Also keep in mind that:

• 🔋 When the air conditioner is turned on, consumption increases by 0.5–1 l/100 km.
• 🚗 Overloading a car (more than 500 kg) increases fuel consumption by 10–15%.
• ⛽ Using AI-98 gasoline instead of AI-95 does not increase power, but can reduce consumption by 2-3%.

⚠️ Attention: B Nissan Cefiro A33 with automatic transmission (RE4F04A) with sharp accelerations, fuel consumption increases to 15–18 l/100 km. To save money, use the mode Overdrive (O/D) and avoid aggressive driving.

If you need to maximize your range, refuel at reputable gas stations (for example, Lukoil, Gazpromneft, Shell) and monitor the tire pressure - a decrease of 0.2 atm increases consumption by 1–1.5%.

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

On most versions Nissan Cefiro A32/A33 To reset the average flow, hold the button RESET (on the dashboard) for 3 seconds. If the button is missing, the reset is done through the on-board computer menu (instructions are in the manual).

Common problems with the fuel system and their solutions

Owners Nissan Cefiro encounter several common problems related to the fuel tank and gasoline supply system:

1. Fuel level sensor malfunction — the arrow on the instrument panel “jumps” or shows incorrect values. Solution: replacing the sensor (part number for A32 — 25080-4M000) or cleaning contacts.
2. Fuel filter clogged - the engine stalls while driving or is difficult to start. Solution: filter replacement (recommended every 30–40 thousand km).
3. Tank corrosion — rust inside leads to particles entering the fuel system. Solution: tank flushing or replacement (for Cefiro A31 tanks are often installed Nissan Laurel as an analogue).
4. Leaking fuel lines — the smell of gasoline in the cabin or under the hood. Solution: replacement of hoses (original art. 16401-4M000 for A32).

If after refueling the engine starts to run intermittently, check:

• 🔍 Fuel quality — try draining the gasoline and refueling at another gas station.
• 🔧 Mass air flow sensor (MAF) - a malfunction leads to a rich mixture.
• ⚡ Spark plugs — carbon deposits or wear increase fuel consumption.

Use a scanner for diagnostics ELM327 or contact a service center with equipment to check the fuel system (for example, a pressure gauge to measure rail pressure).

Tank modifications: can the volume be increased?

Some owners Nissan Cefiro want to increase their range by installing a larger tank. Technically this is possible, but there are some nuances:

• 🔧 Replacement with a tank from another model: for example, from Nissan Maxima (A32) or Laurel (C33). The volume can increase to 80–85 liters, but modifications to the fastenings and fuel lines will be required.
• ⚠️ Installing an additional tank: possible, but changes need to be registered with the traffic police. A popular option is a 20–30 liter tank in the trunk (for example, from UAZ).
• 📏 Making a custom tank: expensive, but allows you to adjust the shape to the body. It is important to use a material that is resistant to corrosion (aluminum or stainless steel).

Before modification please note:

⚠️ Attention: An increase in tank volume by more than 20% of the factory volume requires changes to the vehicle title. Without this, the car will not pass inspection. The fuel level sensor may also need to be reconfigured.

If you need more range without major modifications, consider installation of gas cylinder equipment (GBO). For Cefiro A33 with engine VQ30DD 4th generation gas equipment is suitable, which allows you to save up to 30% on fuel. The downside is the loss of trunk space and the need for regular system maintenance.

FAQ: Frequently asked questions about the tank volume of the Nissan Cefiro

How many liters of tank does a Nissan Cefiro A32 with a 2.5 engine have?

Official volume - 70 liters. However, ~65–68 liters are actually available for refilling due to the tank design and reserve.

Is it possible to fill 92nd gasoline in the Cefiro A33?

Manufacturer recommends AI-95 for engines VQ25DD And VQ30DD. Using 92-octane gasoline can lead to detonation and accelerated valve wear. As a last resort, short-term use of 92 is allowed, but not as a permanent fuel.

Why does the reserve light come on after 100 km of fill-up?

Most likely faulty fuel level sensor or the fuel pump strainer is clogged. There may also be an error in the on-board computer readings. Check the sensor (part no. for A32 — 25080-4M000) and clean the tank of deposits.

What is the range of the Cefiro A31 with a 2.0 engine on the highway?

At a speed of 90–100 km/h and a consumption of ~7.5–8.5 l/100 km, the power reserve is 750–850 km (with 65 l tank). In the city this figure drops to 500–600 km.

Is it possible to install a tank from a Nissan Maxima on a Cefiro A32?

Yes, the tanks are from Maxima A32 (1995–1999) are suitable for fastenings and have volume 70–72 l. However, it may be necessary to replace the fuel lines and modify the level sensor.
