Fuel capacity varies by car make and model
The fuel capacity of a car varies depending on its make and model. The average car's fuel tank capacity typically ranges from 38 to 76 litres (10 to 20 gallons), with some cars holding as little as 26 litres and others as much as 114 litres.
For example, the 2022 Hyundai Elantra has a capacity of 12.4 gallons, while a Mazda3 has a 13.2-gallon tank. The 2022 Honda Civic is rated the same as the Elantra, and the Nissan Versa has an even smaller capacity of 10.8 gallons. Larger sedans tend to have bigger fuel tanks than compact cars, with the 2022 Toyota Avalon offering a 13.2-gallon fuel capacity.
The number of cylinders in a car also affects fuel tank capacity. Two-cylinder cars usually have smaller fuel tanks, typically ranging from 40 to 45 litres. Examples include the Smart Fortwo, Fiat 500, and Chevrolet Spark. Four-cylinder cars commonly have fuel tank capacities between 52 and 56 litres. Six-cylinder cars typically have fuel capacities ranging from 56 to 60 litres, with examples including the Ford Mustang, BMW 3 Series, and Audi A6. Eight-cylinder cars often have larger fuel tank capacities, ranging from 60 to 114 litres. Vehicles in this category include the Ford F-150, Dodge Charger, and Toyota Tundra.
SUVs and trucks tend to have larger fuel tanks to accommodate their higher fuel consumption rates. The Toyota Land Cruiser 300, an SUV, has one of the largest fuel tank capacities at approximately 93 litres. The Audi Q7, another SUV, has a fuel tank capacity of around 85 litres.
It's important to note that the fuel tank capacity is usually indicated in the owner's manual, under the "Specifications" or "Capacities" sections, and can also be found on the manufacturer's website or by contacting the dealership.

How far can a car go when the fuel light turns on?
The average car's fuel tank capacity typically ranges from 38 to 76 litres (10 to 20 gallons), with some sources stating a more conservative range of 45 to 65 litres. This equates to approximately 483 to 644 kilometres (300 to 400 miles) on a full tank, depending on driving conditions and fuel efficiency.
When the fuel light turns on, it usually means there are about two to four gallons left in the tank, or 10% to 15% of its capacity. While there is no concrete answer for how far you can drive, it is estimated to be safe to travel about 20 to 30 miles in a smaller vehicle or up to 50 miles in a larger vehicle. This is supported by a test conducted by YouTuber AutoVlog, who managed 21.6 miles after the fuel gauge on their 4V Ford Fusion reached zero.
However, it is important to note that driving with extremely low fuel can be dangerous for both you and your vehicle. It can damage your engine, air filter, and fuel pump, as well as cause your engine to misfire and even lead to accidents. Additionally, the type of car, driving style, weather conditions, and road conditions can all impact how far you can go when the fuel light turns on. For example, cold weather significantly reduces a vehicle's fuel economy. Therefore, while it may be tempting to push your tank to the limit, it is often not worth the risk.

How to calculate the cost of a full tank
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 enables most cars to cover approximately 483 to 644 kilometres (300 to 400 miles) on a full tank, depending on driving conditions and fuel efficiency.
To calculate the cost of a full tank of gas, you will need to know the number of gallons your car can hold, the number of miles you will be driving, and the price of gas.
Firstly, you can calculate the number of gallons your car can hold by filling up your tank and resetting your odometer. Drive until your tank is empty, or about to be empty, and note the number of miles it took. Then, refill your tank and note the number of gallons it took to fill. Divide the miles driven by the gallons it took to refill, and repeat the process a few times to get an average miles per gallon (MPG).
Once you have your MPG, you can calculate the cost of a full tank of gas for a specific journey. To do this, divide the number of miles you will be driving by your MPG, then multiply the number of gallons needed by the price of gas. This will give you the cost of fuel for your trip.
It is worth noting that gas prices vary across different locations, so be sure to check the price of gas in the area you are travelling to. Additionally, there are ways to reduce fuel consumption and, therefore, the cost of a full tank of gas. For example, removing unnecessary items from your car to make it lighter, keeping windows closed at high speeds, and ensuring your car is properly maintained can all help to reduce fuel consumption.

How to check the capacity of your car's fuel tank
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 enables most cars to cover approximately 483 to 644 kilometres (300 to 400 miles) on a full tank, depending on driving conditions and fuel efficiency.
- Read online resources: Several websites give different specifications of a vehicle; go and check those websites to know the fuel tank capacity of any car.
- Calculate manually: First, determine the dimensions of the tank, like height, length, and breadth for rectangular tanks, and measure the diameter and height for cylindrical tanks. Then, for rectangular tanks, use the formula: volume = length x width x height. For cylindrical tanks, use the formula: volume = πr²h (π = 3.14).
- Fill up the tank: If you are still unsure about the fuel tank capacity of your car, then take it to a fuel pump and get the tank filled. Then you can check the total capacity on the meter of the pump.
- Check the fuel tank cap: Read the writings on the fuel chamber’s cap to find out the capacity of your car. If it reads 60L, it means that a gasoline tank can contain 60 litres of fuel.
- Contact the manufacturer: Contact the local dealership or refer to the car manual to know the fuel tank capacity. You can also check the social media page of the manufacturing brand, where they may have posted about the features of the car.
It is important to know the fuel tank capacity of your car to understand its capabilities and plan your journeys effectively. Additionally, knowing the capacity can help you avoid damaging the engine by ensuring that you refuel when the tank is still at least 1/4 full.

The benefits of keeping your tank full
The fuel tank capacity of an average car typically ranges from 38 to 76 litres (10 to 20 gallons), with variations based on the make and model. This capacity enables most cars to cover approximately 483 to 644 kilometres (300 to 400 miles) on a full tank. Keeping your tank full has several benefits, and here are some of them:
Avoid Engine Damage
Firstly, keeping your tank at least a quarter full at all times can prevent engine damage. Driving with a near-empty tank can cause the engine to draw sediment from the bottom of the tank, which can lead to engine parts overheating and increased friction. This can result in costly repairs.
Safety
Secondly, a full tank can provide peace of mind and enhance safety. Running out of gas can leave you stranded in unsafe locations or dangerous situations, such as being stuck in an accident or traffic jam without a means to keep your vehicle running.
Convenience
Additionally, maintaining a full tank reduces the frequency of refuelling stops. While it may not save time in the long run, it decreases the time spent at each fuelling station. This is especially beneficial in unfavourable areas or during winter, when pumping gas can be more dangerous or challenging.
Fuel Economy
Some studies suggest that a full tank may improve fuel economy. Although the relationship between fuel economy and tank capacity is debated, a full tank allows you to drive much further than a half-empty one, reducing the need for frequent visits to the gas station.
Prevent Fuel Issues in Winter
In cold climates, keeping the tank more than half full during winter is advisable. This helps minimise condensation and avoid issues with freezing fuel lines, as you cannot control the ethanol content or how your vehicle's engine responds to it.
