Vauxhall Agila Fuel Tank Capacity: Size, Range and Fuel Guide

If you are trying to find the Vauxhall Agila fuel tank capacity, the answer depends mainly on which generation of the Agila you own.

The first-generation Vauxhall Agila (Agila A) has a fuel tank capacity of approximately 41 litres, while the second-generation Vauxhall Agila (Agila B) uses a larger 45-litre fuel tank. Official Vauxhall documentation confirms a 41-litre tank for earlier models and a 45-litre tank for the later generation.

That difference may seem small, but combined with the improved fuel economy of later Agila models, it can noticeably affect how far we can travel between fuel stops.

Let's look at the Vauxhall Agila fuel tank size in more detail, including the different engines, realistic driving range, fuel economy and how much fuel we may actually need when filling the car.

What Is the Vauxhall Agila Fuel Tank Capacity?

The Vauxhall Agila fuel tank capacity ranges from 41 to 45 litres depending on the generation.

Earlier Agila models have the smaller 41-litre tank, while the redesigned model introduced for the 2008 model year increased capacity to 45 litres.

Vauxhall's documentation for the earlier Agila lists a 41-litre fuel tank, equivalent to roughly 9 UK gallons.

For the later Agila, official specifications list:

Fuel tank capacity: 45 litres (9.9 UK gallons).

This capacity applies across several petrol and diesel versions of the second-generation car.

Vauxhall Agila Fuel Tank Capacity by Generation

Understanding which generation we have is the easiest way to identify the correct tank capacity.

Vauxhall Agila A Fuel Tank Capacity

The first-generation Agila was the compact, tall-bodied city car closely related to the Suzuki Wagon R+.

Its fuel tank capacity is:

41 litres

That works out at approximately:

9.0 UK gallons or around 10.8 US gallons.

Official Vauxhall documentation for the earlier model specifically states a fuel tank capacity of 41 litres.

A 2004 Vauxhall specification brochure also gives the same 41-litre figure.

Therefore, if we own an Agila from the early-to-mid 2000s, 41 litres is generally the figure we should expect.

Vauxhall Agila B Fuel Tank Capacity

The second-generation Agila arrived with a substantially more modern design and was closely related to the Suzuki Splash.

Its tank is slightly larger:

45 litres

That's approximately:

9.9 UK gallons or about 11.9 US gallons.

Vauxhall's 2009 owner's manual lists a nominal 45-litre tank capacity for the K10B, K12B and D13A engines.

That means the capacity is essentially the same whether we're looking at many of the 1.0-litre petrol, 1.2-litre petrol or 1.3-litre diesel versions.

Vauxhall Agila 1.0 Fuel Tank Capacity

We need to pay attention to the generation when searching for the Vauxhall Agila 1.0 fuel tank capacity, because both generations were available with small petrol engines.

An older Agila 1.0 generally has a:

41-litre fuel tank.

For example, technical data for the original 1.0 12V Agila confirms a capacity of 41 litres.

The later Agila 1.0 ecoFLEX has the larger:

45-litre fuel tank.

Specifications for the second-generation 1.0 ecoFLEX also confirm the 45-litre figure.

So we shouldn't assume that all Agila 1.0 models have the same tank.

Vauxhall Agila 1.2 Fuel Tank Capacity

The same distinction applies to the popular 1.2-litre petrol engine.

Early Agila 1.2 models generally use the:

41-litre tank.

Second-generation 1.2 models use the:

45-litre tank.

For example, specifications for the later 1.2i 16V model list a 45-litre capacity.

The 1.2-litre automatic also has a 45-litre tank.

Therefore, whether we have a manual or automatic second-generation 1.2, the nominal tank size should normally remain the same.

Vauxhall Agila 1.3 Diesel Fuel Tank Capacity

Some second-generation Agila models were available with a small diesel engine.

The 1.3 diesel uses a:

45-litre fuel tank.

Vauxhall's owner's manual groups the D13A diesel together with the K10B and K12B petrol engines and lists a nominal tank capacity of 45 litres for all three.

Because diesel versions can return strong fuel economy, the diesel Agila can potentially travel considerably farther on one tank than the petrol versions under suitable driving conditions.

How Many Gallons Does a Vauxhall Agila Hold?

UK drivers will often see fuel economy expressed in miles per gallon even though fuel is sold by the litre.

For the Vauxhall Agila, the approximate figures are:

The distinction between UK and US gallons is important.

An Imperial or UK gallon is larger than a US gallon, so we should never compare UK MPG figures directly with US fuel economy figures without converting them.

How Far Can a Vauxhall Agila Travel on a Full Tank?

The Vauxhall Agila range on a full tank varies considerably depending on the engine, transmission and driving conditions.

With a 41- or 45-litre tank and the Agila's relatively economical engines, roughly 350 to 500 miles per tank can be achievable under suitable conditions.

However, we shouldn't treat this as a guaranteed figure.

City driving, cold starts, short journeys and heavy traffic tend to reduce range. Long motorway journeys at sensible speeds normally improve it.

Vauxhall Agila 1.0 Range on a Full Tank

The later 1.0 ecoFLEX is one of the most economical Agila versions.

Official specifications for one 1.0 ecoFLEX variant quote combined fuel economy of around 58.9 mpg UK, with a 45-litre tank.

In perfect laboratory-style conditions, that combination suggests a theoretical range approaching 580 miles.

Real-world driving will generally deliver less because we rarely use every drop in the tank and actual fuel consumption changes according to traffic, temperature, tyre pressures and driving style.

For practical planning, leaving a safety margin is much wiser than trying to achieve the theoretical maximum.

Vauxhall Agila 1.2 Range on a Full Tank

Later manual 1.2-litre Agila models can also be impressively economical.

One 1.2 manual specification quotes approximately 55.4 mpg combined, together with the 45-litre tank.

Automatic models typically use more fuel.

For example, one later 1.2 automatic specification quotes around 49.6 mpg combined, while retaining the same 45-litre capacity.

Consequently, two Agilas with identical tank sizes can have noticeably different ranges simply because one uses a manual gearbox and the other an automatic.

Why Can't I Put 45 Litres Into an Empty Agila?

One of the most common misunderstandings regarding fuel tank capacity is expecting to put the manufacturer's full advertised capacity into the car every time the warning light appears.

If your Agila has a 45-litre tank and you can only add 35 or 40 litres at the filling station, that does not automatically mean anything is wrong.

The low-fuel warning normally comes on while some petrol remains in the tank.

Furthermore, the quoted capacity is a nominal specification. The amount we can actually add depends on how much fuel was already present, the position of the vehicle and when the fuel pump nozzle automatically shuts off.

For this reason, trying to force exactly 45 litres into the tank is unnecessary.

Is the Vauxhall Agila Fuel Tank Really 45 Litres?

Yes, for the second-generation Agila.

Multiple Vauxhall specifications list 45 litres (9.9 gallons) as the fuel tank capacity.

Specifications for individual 1.0 and 1.2 versions also consistently show the same 45-litre figure.

The 41-litre figure found online generally refers to the earlier first-generation Agila rather than the later model.

Where Is the Fuel Tank on a Vauxhall Agila?

The fuel tank sits underneath the rear portion of the vehicle.

From the driver's perspective, however, all we normally need to access is the external fuel filler flap and cap.

On older Agilas, the procedure can involve unlocking the filler cap using the ignition key. Vauxhall's earlier quick-reference documentation describes locking the filler cap with the ignition key after refuelling.

If the filler cap becomes difficult to remove, we should avoid forcing it excessively, particularly on an older vehicle where plastic components, seals and locking mechanisms may have deteriorated.

What Fuel Does a Vauxhall Agila Use?

Most Vauxhall Agilas on UK roads use either petrol or, on certain versions, diesel.

The earlier owner's information specifically instructs drivers of petrol models to use unleaded fuel.

The exact recommended octane rating can depend on the engine and model year, so the safest source is the vehicle's fuel flap label or owner's manual.

We should never put diesel into a petrol Agila or petrol into a diesel Agila.

If the wrong fuel has been added, avoiding starting the engine can significantly reduce the potential complications. Professional assistance should then be sought before operating the vehicle.

How Much Does It Cost to Fill a Vauxhall Agila?

The answer depends entirely on the current price of fuel.

The calculation is simple:

Tank capacity × fuel price per litre = approximate cost of a completely full tank.

For example, an Agila B can hold up to approximately 45 litres.

In reality, a normal fill-up will usually cost less than the theoretical cost of 45 litres because some fuel will still be inside the tank when we arrive at the petrol station.

The older Agila's 41-litre tank will naturally cost slightly less to fill from completely empty.

Does the Fuel Warning Light Mean the Tank Is Empty?

No.

A low-fuel warning means we should refuel soon, not that the fuel tank contains absolutely nothing.

Manufacturers deliberately leave some usable fuel remaining when the warning appears.

Exactly how far an Agila can travel after the warning light comes on is difficult to guarantee because fuel consumption can change dramatically.

Instead of thinking in terms of a fixed number of miles, it is safer to treat the warning light as our signal to find a petrol station.

How to Improve Vauxhall Agila Fuel Range

The Agila was designed as an economical small car, but our driving habits still have a significant influence on how far one tank lasts.

Useful ways to reduce fuel consumption include:

• keeping the tyres at the recommended pressure;
• accelerating smoothly;
• avoiding unnecessary heavy braking;
• removing unnecessary weight from the car;
• avoiding excessive idling;
• keeping the engine properly serviced;
• reducing unnecessary high-speed driving;
• using the correct engine oil specification;
• checking for dragging brakes or poorly aligned wheels;
• combining short journeys where practical.

Even relatively small improvements in MPG can add up over an entire 41- or 45-litre tank.

Does Air Conditioning Reduce Agila Fuel Range?

It can.

The air-conditioning compressor requires energy from the engine, which can slightly increase fuel consumption.

The difference is usually more noticeable during slow urban driving than during steady motorway cruising.

That doesn't mean we should avoid air conditioning altogether. Comfort, visibility and demisting can be more important than saving a very small amount of fuel.

However, constantly running maximum air conditioning when it isn't needed may slightly reduce the distance we achieve from a tank.

Does Driving Speed Affect Fuel Tank Range?

Absolutely.

Fuel tank capacity remains fixed, but range changes according to how quickly the engine consumes that fuel.

A Vauxhall Agila driven gently at moderate speeds can return much better fuel economy than the same car driven aggressively.

At motorway speeds, aerodynamic resistance rises significantly as speed increases.

The Agila's tall body is particularly relevant here. It was designed primarily as a practical compact city car rather than an aerodynamic long-distance motorway vehicle.

Consequently, maintaining very high speeds can reduce MPG more noticeably than we might expect.

Why Is My Vauxhall Agila Using More Fuel Than Expected?

Higher fuel consumption doesn't necessarily indicate a serious mechanical problem.

Traffic, frequent cold starts and winter temperatures can all affect MPG.

However, a sudden or substantial change is worth investigating.

Potential factors include underinflated tyres, worn spark plugs, a dirty air filter, faulty sensors, binding brakes, wheel-alignment issues or an engine-management problem.

If the car also displays an engine warning light or runs poorly, diagnostic testing may help identify the cause.

Fuel Tank Capacity vs Usable Capacity

When manufacturers state a fuel tank capacity such as 45 litres, they are quoting the nominal total capacity.

Drivers should not assume that every litre is practically usable under every condition.

Fuel can move inside the tank during cornering, braking or driving on steep inclines. Fuel-pump systems are also designed to keep the pump supplied reliably rather than allowing us to extract the very last drop.

This is another reason why deliberately driving until the engine runs out of fuel isn't recommended.

Should We Always Fill the Agila Fuel Tank Completely?

Not necessarily.

Filling the tank completely is convenient when we want maximum driving range or want to minimise visits to the petrol station.

Adding a smaller amount can also be perfectly acceptable.

A full tank does add some weight to the car, but for normal everyday driving the difference in fuel economy is relatively minor.

Convenience is usually the more important consideration.

If we're planning a long journey, starting with a full tank is often worthwhile.

Vauxhall Agila Fuel Tank Capacity Compared With Similar Cars

A capacity of 41 to 45 litres is quite reasonable for a compact city car of the Agila's era.

Small cars do not require enormous tanks because their relatively economical engines allow respectable driving ranges from comparatively modest quantities of fuel.

The later Agila's 45-litre tank is especially useful because its efficient 1.0 and 1.2 petrol engines can potentially deliver a substantial range between fill-ups.

This combination helped make the Agila practical not only for urban trips but also for longer journeys.

Is the Vauxhall Agila Economical to Run?

In general, fuel economy was one of the Agila's strengths.

Second-generation 1.0 ecoFLEX models were officially rated at around the high-50s to approximately 60 mpg combined depending on version, while several 1.2 manuals were rated in the mid-50s.

Actual MPG depends heavily on vehicle condition and usage, particularly now that surviving Agilas may be many years old.

A well-maintained example used for mixed driving can still make sense as an inexpensive small car.

Vauxhall Agila Fuel Tank Specifications at a Glance

The most important distinction is straightforward.

The original Vauxhall Agila has a 41-litre fuel tank, while the second-generation Vauxhall Agila has a 45-litre tank.

For most people searching for the capacity of a 2008-onward Agila, therefore, 45 litres is the figure to remember.

The different engines in the later generation generally use the same nominal tank size, meaning driving range depends more on fuel economy than tank capacity.
