Fuel tank volume largely depends on its structure. Different vehicle models have their own design.
What determines the volume of the fuel tank?
The volume indicators must be such that the car’s mileage can be 600 kilometers. It is usually installed from below the rear seat opposite the rear axle. It is in this place, according to all calculations, that there is the lowest probability of deformation if an impact suddenly occurs.
Plastic or metal can be used to make the tank. Moreover, today plastic tanks are more often used - not least because they take up less space when installed and can be of any desired shape. Thus, the driver receives a fuel tank with the required maximum volumes. To avoid any leakage, the walls of the tanks are made multi-layered. These indicators can also be affected by:
- body type;
- system design;
- general configuration;
- system responsible for injection;
- climate control option;
- propulsion device.
The dimensions of the car also affect the volume: usually large cars have large fuel tanks.
Fuel system
Sometimes the structure and, accordingly, the volumes of the tank turn out to be different even when using the same model as an example. To enable the tank to be refilled, it has a filler neck. In fact, this part turns out to be the only one noticeable from the outside. Most often it is located on top of the rear wing.
The presented part is connected to a pipeline tank, and the cross-section is made in such a way that it ensures the ability to flow fifty liters/minute. The neck can be closed using a cap placed on the thread. Everything is hidden by a hatch that opens using a special drive (which can be powered electrically or mechanically). Sometimes the hatch can be opened manually.
Fuel enters the power system through an intake connected to the outlet of the fuel wire. The remainder is drained back through the fuel drain line. You can close the intake with a mesh that is specially made to clean out fuel. This device, installed on a diesel car, is equipped with a special heating system. Sometimes car owners use a standard intake instead of a heated one. They can also access heating attachments.
A fuel pump that runs on electricity is usually placed in the gas tank; it is this pump that must pressurize the fuel. The fuel level is controlled by a sensor that is connected to a pumping device.
The components of the sensor are a potentiometer as well as a sensor. As soon as the fuel volume changes, the potentiometer readings change. As a result, there is a change in voltage followed by a change in the needle. With a complex design, a pair of sensors are installed in the tank at once, operating in parallel.
In order for the engine to receive the required amount of fuel, constant pressure must be maintained inside the tank. To do this, the vehicle has a ventilation system - thanks to it, the vacuum that appears when fuel is produced is neutralized. A special valve is needed to remove excess air that ends up inside during refueling and prevents the pressure from rising.
Tank care
Regardless of the volume of the tank, it should be properly cared for. This is especially true for cars with high mileage. Unfortunately, due to the poor quality of the fuel, impurities end up in the tank along with hydrocarbons, which settle on its walls. When they accumulate, they peel off and contaminate the filter responsible for rough cleaning. As a result, fuel simply does not pass through the intake.
Solving this problem, however, is not difficult. Needs cleaning. It will also help increase the volume of the fuel tank. Usually the insides of the tank are washed with special chemicals.
Fuel tank design
As mentioned above, you can determine the volume of the fuel tank by first finding out what it is made of: plastic material or metal. Metal tanks are usually made from stamped sheets:
- if they run on gasoline or diesel, aluminum is used;
- if work is carried out on gas, steel is used.
Of course, metal tanks are distinguished by high strength and wear resistance - however, in terms of volume they are usually inferior to plastic ones. In addition, there are limitations associated with forms.
But tanks made of plastic can be made in various configurations and, accordingly, have different volumes. In addition, these products are famous for their resistance to scratches, corrosion, and have good density.
Leaks in them are impossible, since the walls are made in several layers. The inner part is treated with a protective fluorine layer. Also, differences between fuel tanks may be due to:
- ICE type;
- Body;
- Design features;
- Fuel supply system.
What are the tank sizes?
As already indicated, different models and, especially, car brands may have their own volumes. For example, Ford fuel tank capacity equals approximately 50-55 liters, depending on the model and type of fuel used. As a rule, this is enough to move freely over long distances and not have to refuel every day.
Inside the tank, by the way, there is a sensor that monitors the fuel level. Pumping devices are also located in some models (for example, Ford Focus). When they are installed on diesel-powered vehicles, the operating principle is special: fuel is pumped and supplied directly to the system.
Finally, all Fords have a fuel line - both forward and reverse. When repairing a tank, fuel material is removed through the neck where fuel is poured.
- Toyota fuel tank capacity can range from 45 liters (Toyota Tercel) to 98 liters (Toyota Sequoia). If we talk about the most popular models, on average these figures are 50-70 liters.
- KIA fuel tank capacity equals, on average, 55 liters, although, of course, there are models with smaller and larger figures. Moreover, the newer the model (this can be seen in the example of the Kia Sportage), the smaller the fuel tanks become.
- GAS fuel tank volume is about 70 liters. Naturally, such a container can fit enough fuel material.
- Nissan fuel tank capacity ranges from 50 liters (Nissan 200SX) to 106 liters (Titan, Armada, QX56 and so on). As for the most popular models, like the Nissan Maxima or Nissan Frontier, their volume figures are 60-65 liters.
- VAZ fuel tank volume- at least for many models of this car brand - is 39 liters. The container itself is made up of two parts, for stamping which lead sheets are used. A filter in the form of a mesh is also mounted in such tanks - it helps to carry out primary filtration of fuel. So that gasoline can be drained, there is a drain plug and getting there is as easy as pie: remove the rubber plug that covers the hole at the bottom of the trunk.
- Renault fuel tank capacity equals 50 liters if it is a Duster model (in this case plastic tanks are used) and 50 liters for a Logan model. By the way, in terms of fuel consumption, these cars are considered quite economical: for example, on city roads Renault can consume about 10 liters, on the highway - only 5.7 liters. If the road surface is mixed, approximately 7.2 liters are consumed.
- Hyundai fuel tank capacity, as with other cars, depends on the specific model. Typically this range varies from 45 liters (Hyundai Accent) to 79.9 liters (Sorento or Sedona). The Sonata model, popular among car enthusiasts, has a tank of 65 liters.
- UAZ fuel tank volume ranges from 56 liters (for example, model 390945) to 87 liters (Patriot model). The UAZ Bukhanka has a fuel tank reaching 56 liters, but the popular UAZ Hunter has a tank with a capacity of 78 liters.
- Kamaz fuel tank volume, of course, exceeds the indicators listed above, since we are talking about a truck. The approximate range ranges from 175 liters (models 55102 and 5511) to 500 liters (model 65117). Typically, Kamaz truck models have fuel tanks with a volume of 350 liters.
Knowing working volume of the fuel tank, you can roughly understand how long and how far the car can travel without having to refuel again. A lot also depends on the configuration of the fuel tank, what fuel is used and, finally, what type of engine.
Maximum capacity of fuel tanks limited by a special international agreement relating to dangerous goods transport. When devices exceed the volume limits specified in this agreement, they automatically begin to be considered dangerous goods (problems may arise when crossing the border). Moreover, this is considered “dangerous cargo”, regardless of how much fuel is contained inside.
The following table summarizes the fuel tank capacity of some car brands:
| Ford | 50-55 liters |
| Toyota | 45-88 liters |
| KIA | from 55 liters |
| GAS | 70 liters |
| NISSAN | 50-106 liters |
| VAZ | from 39 liters |
| Reno | 50 liters |
| Hyundai | 45-79.9 liters |
| UAZ | 56-87 liters |
| Kamaz | 175-500 liters |
Of course, drivers most often do not allow the gasoline light to come on in the car, which warns of low fuel level in the tank. This warning indicates that it is time to refuel the vehicle. But should we immediately go to the gas station and refuel the car as soon as possible? How much longer do we have before our car runs out of petrol or diesel? Here is a detailed table for many car models that details how much fuel is left in the tank after a low petrol or diesel warning appears on the dashboard.
The table published below provides approximate values for a particular car model. Please note that the data is provided for cars manufactured up to 2015 inclusive. Also keep in mind that some values in the table may differ slightly from actual values.
But on average, the following values are obtained: passenger cars, after the fuel level light in the tank comes on, can still travel about 50 kilometers, while SUVs and crossovers, which usually have an increased volume of fuel tanks, can drive with the fuel light on approximately another 150 kilometers.
Does this mean that car owners may not rush to the gas station when they see a low fuel warning on their dashboard? Of course not. Especially if you are in an unfamiliar area and have no idea how far the next one will be.
That is, despite the fact that in any car the fuel tank has a certain reserve of fuel, after the warning lamp appears, indicating a low fuel level in the tank, you should refuel your car as soon as possible and next time do not allow this warning to appear again. Always keep the fuel level in the tank until the fuel light appears on the dashboard.
Is it dangerous to drive with low fuel in the tank?
Many people do not know, but in addition to the risk of being left without fuel if the warning about low fuel level is ignored, there are a number of problems that any car owner who often drives on an empty tank may encounter.
For example, frequent trips on an empty tank can prematurely damage the catalyst in the exhaust system, which will have to be repaired or purchased a new one, which is associated with huge financial expenses.
Frequent trips with low fuel levels in the tank can damage the fuel pump. The fact is that the fuel that we fill at gas stations is actually not clean (especially in Russia) and it contains various fractions of pollution that settle at the bottom of the tank. When the fuel level is low, we risk that such sediment may enter the fuel system through the fuel pump. Especially, . It is at this moment that sediment particles from the tank can enter the fuel pump. At a normal fuel level, such a risk of contamination of the fuel system is minimal.
So if you don’t want to ruin your car, then refuel your car regularly and on time, without bringing the fuel level to low levels, which lead to the appearance of a burning lamp on the dashboard.
Is the range shown on the car's on-board computer accurate?
Many car owners often rely on the vehicle's on-board computer, which shows you the possible range. Therefore, some drivers bring the car to a low fuel level, relying on the on-board computer indicator, believing that the indicated range is true.
Also, many drivers, when a warning about low fuel level appears, immediately look at the on-board computer readings in order to find out how much longer the car can travel on the fuel remaining in the tank (power reserve).
But unfortunately, the range isn't accurate because it's only based on the average of your past driving on the road.
The fact is that the car’s electronics will not be able to show you the true range, since it cannot take into account in real time your current driving conditions that affect the consumption of gasoline or diesel fuel.
For example, if you were driving on the highway before a light appeared on the dashboard warning you about the low fuel level in the car tank, and now you are stuck in a traffic jam, then the range displayed on the on-board computer is actually incorrect, since this indicator is calculated using driving on the highway, where fuel consumption is actually much less than in heavy traffic in the city.
So don't expect to be able to drive very far when there is a low fuel warning.
So how much fuel is left in the tank from the moment the fuel light appears on the dashboard and how many kilometers can you still drive before the fuel is completely used up?
If the first question can still be answered quite simply, then how much further distance can you drive on an empty tank after the fuel light on the car’s dashboard comes on, it’s very difficult to say unequivocally, since it depends on the actual fuel consumption of your car at a certain moment time.
And consumption depends on many factors, ranging from your driving style and weather conditions, as well as the tires installed on the car and the road surface.
We have already disclosed in detail information about the power reserve on an empty tank. .
This same article complements the previous one and also expands useful information for car enthusiasts.
Here is a detailed table by car model that shows you in detail how much fuel is left in the tank in your car after the low fuel warning light appears on the dashboard. Also from the table you will find out what distance on average you can travel after a warning about an empty tank.

Yes, sometimes we may find ourselves in a situation where we cannot refuel our car in time. In this case, sooner or later a warning will appear on the tidy that gasoline or diesel will soon run out.
We advise you not to ignore this warning from your vehicle's electronics. But there is no need to panic. You still have time to find a gas station to fill up your car. Thanks to this table, you can find out approximately how much fuel you have in the tank, as well as what the vehicle's range is after the lamp appears indicating low fuel level in the tank.
Each car has its own. There is no specific standard for the volume parameter that all car manufacturers adhere to. Let's figure out what the capacities of different types of fuel tanks are, determine the features and design of these elements.
How do manufacturers calculate
It is believed that a car should have enough fuel so that it can travel 500 kilometers at one filling station. This is an unspoken rule that many automakers adhere to. Consequently, the fuel tank capacity will be different for vehicles with high and low fuel consumption.
On average, a fuel tank holds 55-70 liters of gasoline, however, due to the reduced fuel consumption of small engines, there is a tendency for the fuel tank capacity to decrease. This is logical, because a passenger car with a small engine displacement needs much less fuel to travel 500 km. In addition, the efficiency of the fuel itself increases due to an increase in octane number and the use of various additives, which also implies savings and a reduction in tank capacity. A large jeep with a voracious engine will “eat” much more gasoline, therefore, its fuel tank should be larger.
When it comes to diesel, the fuel tank of diesel-powered cars is often smaller compared to gasoline-powered cars. This is logical, since the efficiency of diesel fuel is higher than the efficiency of gasoline. Therefore, a car with a 40-liter tank completely filled with diesel fuel will travel the same distance as a car with a full 50-liter tank. But this is too rough a comparison.
Fuel tanks of passenger cars
To roughly understand the numbers, you need to refer to the technical parameters of the cars. The new Lada Vesta from the Russian concern AvtoVAZ is equipped with a tank with a capacity of 55 liters. This is a fairly high figure, and its closest competitors - Kia Rio and Hyundai Solaris - are equipped with 43-liter tanks. The fuel consumption of these cars is approximately the same, which means that the Lada will travel a longer distance when fully refueled, which is one of the advantages.
The larger Volkswagen Tiguan is equipped with a tank with a capacity of 58-64 liters (depending on the specific modification), and such huge cars as the Toyota Land Cruiser, with high fuel consumption, have 93-liter tanks.
As for sizes, this is much more complicated. Some manufacturers make rectangular tanks, the size of which can be approximately 60x40x20 cm. There are tanks with completely different sizes, and some manufacturers adapt these fuel containers so that they fit into the design. Their size cannot be described by three or four parameters.
Truck tank capacities
As for trucks, the KamAZ vehicle is popular, the fuel tank of which, depending on the model, can have a different volume. The minimum capacity is 125 liters. However, due to high fuel consumption, KamAZ is not able to travel a long distance (and even with a load) on such a tank, so the manufacturer has provided other tanks that are used on this vehicle. Thus, the KamAZ fuel tank can have a capacity from 125 to 600 liters in increments of 50 or 40 liters.
There may also be non-standard modifications of 700 liter tanks. The fact is that not only the manufacturing plant produces fuel containers, third-party manufacturers can also do this. In general, there is little chance of finding products from the KamAZ plant on the market; tanks from third-party manufacturers are most often found.
The second popular truck is GAZelle. Despite the fact that this vehicle is a truck, the GAZelle’s fuel tank holds only 60 liters of gasoline. And this is very inconvenient, given that the car’s fuel consumption is quite high. Consequently, when driving long distances you have to take extra fuel cans with you.
Some owners of these cars replace the old, small tank with a new one. Third-party manufacturers produce fuel tanks for GAZelle with a capacity of up to 150 liters.
All this allows us to conclude that the fuel tank is a changing, not a constant quantity, and it is different for different cars. Even two identical models can use completely different fuel containers with different capacities.
Huge trucks like SCANIA 113 even have tanks of 450-500 liters. The XF can have an 870-litre fuel capacity, while the heavy-duty F90 comes with a 1,260-litre tank. This is simply an incredibly large capacity, and the small 45-liter tanks of passenger cars look simply ridiculous in comparison.
Fuel tank design
Now that we understand how many liters of gasoline a fuel tank can hold, we can talk about its design. On passenger cars it is placed in the rear of the body, under the passenger seats. At the same time, it is covered with a durable metal plate to avoid deformation during a collision, and is also insulated from overheating using special heat-insulating gaskets.
Material
Tanks can be made of metal, aluminum, plastic. Aluminum tanks are used to store diesel and gasoline fuel, steel tanks are used for gas. As for plastic tanks, they have become very popular recently due to their ease of production and molding. Due to the ability of plastic to quickly acquire the desired shape, manufacturers create tanks of various design complexities. In addition, this material does not corrode and protects well from leaks thanks to the use of various technologies (coating the internal surface with fluorine is one of them).
Fuel filler neck
The tank is filled through the neck, which is most often located above the rear fender on the right or left side. Experts explain that the ideal location for the fuel tank neck from a safety point of view is the left side, since when refueling this reduces the chances of starting before the nozzle is removed from the tank. This way the driver has better control over the process.
The neck is connected to the tank through a pipeline, and it is located under a special fuel tank neck cap. This cover on older cars opens from the outside (that is, any passerby can open it), but on modern cars the cover opens from the passenger compartment. The most commonly used method is a mechanical opening method using a cable.
Fuel line
Gasoline or diesel fuel is supplied to the engine power system through the fuel output line. A fuel pump is also used for this, which pumps gasoline from the tank into the engine power system. The fuel that is not consumed by the engine is returned to the tank. So gasoline constantly circulates through the fuel line: part of it is spent on engine operation, and the second is returned back.
Level control sensor
This sensor is found in all tanks and is part of the fuel pump. If the gasoline level decreases, the float moves lower. This entails a change in the resistance of the potentiometer associated with the float. As a result, the voltage in the electrical network drops, and the arrow on the dashboard displays the change. This way the driver sees how much gasoline is left in the tank.
Ventilation
One of the important systems is ventilation. The fact is that the pressure in the tank must always be maintained equal to atmospheric pressure, and ventilation is responsible for this. Modern machines are equipped with a closed tank ventilation system, which prevents a drop or increase in pressure inside it. If the pressure inside the container decreases, it may become deformed, and an increase in pressure may generally tear the tank into pieces. Considering that there is fuel inside, a lot of attention is paid to implementing an effective ventilation system.
When fuel leaves the tank, the pressure in it drops, resulting in a vacuum. Thanks to the ventilation system, this effect is eliminated: a safety valve allows air inside. This valve is located at the neck cap and can only allow air to flow in one direction.
When refueling, excess air enters the tank, which causes the formation of gasoline vapors. These excesses are displaced by the ventilation system through a special pipeline. Also, gasoline vapors can form at elevated temperatures, which also leads to an increase in pressure. And only the ventilation system saves the tank from completely breaking into pieces.
Conclusion
The fuel tank of a car is a rather complex structure. Despite the apparent simplicity of the device, many different processes occur in the tank (evaporation, fuel oxidation), which must be taken into account when developing these containers. But if you compare the design of the tank with a motor or at least with a power system, it will seem primitive.
Now you know how the fuel tank works, how big it is in cars and trucks, and why it's so small in small cars. Against the backdrop of all this, the tendency to reduce tank capacity in modern
Using an online calculator, you can correctly calculate the volume of a container such as a cylinder, barrel, tank, or the volume of liquid in any other horizontal cylindrical container.
Let's determine the amount of liquid in an incomplete cylindrical tank
All parameters are indicated in millimeters
L— Height of the barrel.
H— Liquid level.
D— Tank diameter.
Our online program will calculate the amount of liquid in the container, determine the surface area, free and total cubic capacity.
The determination of the main parameters of the cubic capacity of tanks (for example, a regular barrel or tank) should be made based on the geometric method for calculating the capacity of the cylinders. In contrast to methods for calibrating a container, where the volume is calculated in the form of real measurements of the amount of liquid using a measuring ruler (according to the readings of the meter rod).
V=S*L – formula for calculating the volume of a cylindrical tank, where:
L is body length.
S is the cross-sectional area of the tank.
According to the results obtained, capacity calibration tables are created, which are also called calibration tables, which allow you to determine the weight of the liquid in the tank by specific gravity and volume. These parameters will depend on the filling level of the tank, which can be measured using a meter rod.
Our online calculator allows you to calculate the capacity of horizontal and vertical containers using a geometric formula. You can find out the useful capacity of the tank more accurately if you correctly determine all the main parameters that are listed above and are involved in the calculation.
How to correctly define master data
Determining the lengthL
Using a regular tape measure, you can measure the length L of a cylindrical tank with a non-flat bottom. To do this, you need to measure the distance between the intersecting lines of the bottom with the cylindrical body of the container. In the case of a horizontal tank with a flat bottom, then in order to determine the size L, it is enough to measure the length of the tank along the outside (from one edge of the tank to the other), and subtract the bottom thickness from the result obtained.
Determine the diameter D
The easiest way is to determine the diameter D of a cylindrical barrel. To do this, it is enough to use a tape measure to measure the distance between any two extreme points of the lid or edge.
If it is difficult to correctly calculate the diameter of the container, then in this case you can use the measurement of the circumference. To do this, use a regular tape measure to circle the entire tank around the circumference. To correctly calculate the circumference, two measurements are taken in each section of the tank. To do this, the surface being measured must be clean. Having found out the average circumference of our container - Lcr, we proceed to determining the diameter using the following formula:
This method is the simplest, since often measuring the diameter of a tank is accompanied by a number of difficulties associated with the accumulation of various types of equipment on the surface.
Important! It is best to measure the diameter in three different sections of the container, and then calculate the average value. Since often, these data can differ significantly.
Averaged values after three measurements allow us to minimize the error in calculating the volume of a cylindrical tank. As a rule, used storage tanks undergo deformation during operation, may lose strength, and decrease in size, which leads to a decrease in the amount of liquid inside.
Determining the levelH
To determine the liquid level, in our case it is H, we need a meter rod. Using this measuring element, which is lowered to the bottom of the container, we can accurately determine the parameter H. But these calculations will be correct for tanks with a flat bottom.
As a result of calculating the online calculator, we get:
- Free volume in liters;
- Amount of liquid in liters;
- Volume of liquid in liters;
- Total tank area in m²;
- Bottom area in m²;
- Lateral surface area in m².
" It seems that the fuel tank is filled more than its nominal capacity!!!" "This has never happened!!!"
Every driver has most likely gone through such an experience. Especially when refueling a car to a full tank, some drivers sometimes doubt the required amount of fuel. Especially when the amount of remaining fuel and filled fuel exceeds the fuel tank capacity officially specified by the car manufacturers. However, if such a difference is only 5-10 liters, this is natural. Because the tank was originally designed to be larger than the rated fuel tank capacity stated in the owner's manual.
Therefore, when the above situation occurs, there is no need to get lost, you just need tocheck the actual difference from the nominal capacity.
1. Official fuel tank capacity (nominal capacity)
① The "rated capacity" of passenger cars is designed for vehicles to drive about *600 km at a speed of 80-100 km/h on highways. The rated capacity is designed taking into account fuel efficiency and vehicle body weight, so it varies depending on the vehicle model and engine size.
*About 600 km is based on the driving distance, provided that the driver drives the car for 5-6 hours a day at a speed of 100 km without physical fatigue (based on 1 refueling per day).
② Why can the car drive another 50-60 km even when the fuel indicator light is on?
The indicator light was developedwith reserve capacity so that the driver can get to the next service area (refueling) (average distance between service areas is about 50-60 km) on the highway, about 10% of the fuel tank capacity.
2. Why is the actual capacity greater than the rated capacity?
If nominalSince the capacity of the fuel tank is 65ℓ, its actual capacity is about 75ℓ. Because when manufacturing the fuel tank, the car manufacturer took into account the free capacity, 10-15% of the nominal capacity. The reason for this is the following:
①It is designed to prevent the release of volatile organic compounds ( VOC ) in case of an increase in volume caused by an increase in air temperature. If the fuel tank is filled to full, there is a danger that due to the increase in internal temperature and therefore internal pressure, fuel may leak out.
②Also, reserve space is left in the tank to prevent fuel leakage when the car is parked on an inclined place with a full tank. This is called "reserve capacity for expansion"
(Note)¹ Maintaining filling volume LPG vehicle fuel tanks (85%)
If you increase the LPG temperature
in a liquid state, its volume increases. Therefore, when filling LPG into a container, it is regulated to ensure that the temperature of the container is maintained below 40℃ and the LPG in liquid state is filled to 85% of the container's volume (90% in the case of a tank tank)
