Fuel tank capacity varies by car type, from compact to SUV
The fuel tank capacity of a car varies depending on the make and model of the vehicle. The average car's fuel tank capacity typically ranges from 38 to 76 litres (10 to 20 gallons), but this can differ based on the type of car, from compact city cars to SUVs and trucks. Compact cars have the smallest fuel tanks of all vehicles, with the 2022 Nissan Versa, for example, offering a 10.8-gallon fuel tank capacity. Larger sedans will have bigger fuel tanks, with the 2022 Toyota Avalon offering a 13.2-gallon capacity, and the 2022 Dodge Charger an 18.5-gallon capacity.
SUVs, which are larger vehicles, tend to have bigger fuel tanks. The Toyota Land Cruiser 300, for instance, has a fuel tank capacity of approximately 93 litres, while the Audi Q7 has a capacity of around 85 litres. The 2022 Chevrolet Suburban holds 28 gallons of gas, and the 2022 Nissan Kicks only holds 10.8 gallons. Some SUVs have smaller capacities, while others rival modern trucks in terms of fuel capacity.
The number of cylinders in a car's engine also affects fuel tank capacity. Two-cylinder cars usually have smaller fuel tank capacities, ranging from 40 to 45 litres. Four-cylinder cars commonly have fuel tank capacities between 52 and 56 litres. Six-cylinder cars typically have fuel tank capacities ranging from 56 to 60 litres. Finally, eight-cylinder cars often have larger fuel tank capacities, ranging from 60 to 114 litres.
Fuel tank capacity is a crucial factor in determining a car's range and refuelling frequency, and it can impact the driver's experience on the road. A full tank of fuel will generally allow a car to travel further than a half-empty one, although fuel efficiency varies across different vehicles.

A larger fuel tank means less frequent refuelling
The fuel tank capacity of a car is crucial as it dictates its range and refuelling frequency. The size of a car's fuel tank varies, with the average tank holding between 38 and 76 litres (10 to 20 gallons) of fuel, or between 45 and 65 litres according to another source. This enables most cars to cover approximately 483 to 644 kilometres (300 to 400 miles) on a full tank, depending on driving conditions and fuel economy.
In contrast, compact cars tend to have smaller fuel tanks to keep the overall vehicle size to a minimum. For instance, the 2022 Nissan Versa has a 10.8-gallon fuel tank, while the Maruti Suzuki S-Presso has a capacity of just 27 litres.
The frequency of refuelling also depends on driving habits and fuel economy. Keeping the tank at least a quarter full can help prevent efficiency-lowering complications such as fuel pump overheating. Refuelling during colder times of the day may also improve fuel economy, although the difference is said to be negligible due to the underground and insulated nature of fuel storage tanks.
Additionally, maintaining proper tyre inflation, avoiding heavy cargo, minimising idling, driving on paved roads, and practising gentle acceleration and braking can all positively impact a vehicle's fuel economy, reducing the need for frequent refuelling.

The average car's fuel tank capacity is 38-76 litres
The fuel tank capacity of a car is an important factor that dictates its range and refuelling frequency, and it directly impacts the driver's experience on the road. The average car's fuel tank capacity typically ranges from 38 to 76 litres (10 to 20 gallons), with variations based on the make and model. This capacity allows most cars to cover approximately 483 to 644 kilometres (300 to 400 miles) on a full tank, depending on driving conditions and fuel economy.
The fuel tank size varies widely among different car types, from compact city cars to SUVs and trucks. Compact cars tend to have smaller fuel tanks, with some as low as 8.7 gallons, while larger vehicles like SUVs and trucks can have larger capacities. The number of cylinders in an engine is also a factor, with two-cylinder cars typically having smaller fuel tank capacities ranging from 40 to 45 litres, while eight-cylinder cars can have capacities ranging from 60 to 114 litres.
The fuel economy of a car is another consideration when discussing fuel tank capacity. Some studies have shown that a full tank can provide better fuel economy than a half-full one due to the density and weight of the fuel. Additionally, having a full tank can reduce the time spent at each fuelling station. However, it's important to note that knowing your miles per gallon (mpg) is often considered more crucial than knowing your tank capacity, as mpg helps anticipate fuel costs and understand your vehicle's efficiency.
While the average car's fuel tank capacity falls within a certain range, there are outliers with significantly larger or smaller capacities. For example, the 2022 Nissan Kicks has a capacity of only 10.8 gallons, while the 2022 Chevrolet Suburban can hold up to 28 gallons. Similarly, the Maruti Suzuki S-Presso has a capacity of just 27 litres, while the Toyota Land Cruiser 300 boasts a capacity of approximately 93 litres.

A full tank improves fuel economy and reduces time at the pump
Fuel tank capacity is an important factor in a car's performance, influencing travel distances and refuelling frequency. The average car's fuel tank capacity typically ranges from 38 to 76 litres (10 to 20 gallons), with some vehicles holding as little as 27 litres and others boasting capacities of up to 114 litres.
A full tank of fuel can improve fuel economy and reduce time spent at the pump. While some argue that a full tank adds weight, reducing efficiency, studies have shown that a full tank can lead to better fuel economy. The difference in weight from a full tank is relatively minor, about 5% of the overall car weight, and filling up completely can help drivers save time and mileage by reducing the frequency of visits to the petrol station.
Additionally, a full tank means you can drive much further before needing to refuel, which is especially beneficial for long-distance trips or driving in areas where petrol stations are scarce. This can also be a safety measure, as spending less time at the pump may reduce the risk of fuelling in unsafe neighbourhoods.
However, it is important to note that other factors, such as proper maintenance, driving style, tyre pressure, and vehicle aerodynamics, also play a significant role in maximising fuel economy. For example, long-distance driving can improve fuel economy, as the engine spends more time running at its engineered temperature. Additionally, removing unnecessary weight from the vehicle, such as spare wheels and accessories, can help improve efficiency by reducing mass.

The fuel tank location is usually below the rear seats
The placement of a car's fuel tank depends on several factors, including the vehicle's design, engineering, and underbody packaging of its components. While there are no regulations specifying the location of the fuel tank, safety requirements dictate that it should be on the widest part of the car, away from the fuel lines, exhaust, and electrical wiring.
Historically, mounting fuel tanks at the rear of the car was a common practice, especially in the early 20th century. Cars like the 1924 Buick, 1926 Buick, and the 1929 Roadster Buckboard featured rear-mounted fuel tanks. This design continued well into the 1970s, with cars relying on vacuum tanks to deliver fuel to the carburetor. However, with the advent of newer technologies, such as the fuel pump, and increasing safety concerns, the placement of fuel tanks began to evolve.
Today, the fuel tank location is usually below the rear seats in many vehicles. This placement provides several advantages, including creating more room in the trunk or rear of the vehicle. For example, the Honda Fit has its fuel tank located under the front seat, allowing for a flat-folding rear seat design. Additionally, this location is considered safe, as modern fuel tanks are made of plastic and are challenging to puncture in the event of a collision.
It's worth noting that the fuel tank capacity can vary significantly among different car types, from compact city cars to SUVs and trucks. The average car's fuel tank capacity typically ranges from 38 to 76 litres (10 to 20 gallons), while larger vehicles like trucks and SUVs tend to have bigger fuel tanks.
