How Big Are Car Gas Tanks? (With Examples)

Last updated on September 5th, 2023 at 12:00 pm

One of the most important factors to consider when buying an automotive vehicle is the gas tank capacity. With a big gas tank, we can avoid frequent fuel stops. However, a big gas tank doesn’t always equate to fuel efficiency and good fuel mileage. 

Large cars with big gas tanks can decrease fuel efficiency. For example, a large gas tank weighs more, especially when fully loaded. As a result, the car needs more energy to function, leading to more fuel consumption and engine activity.

So, how big are car gas tanks? A car gas tank’s size and capacity vary per vehicle type, size, trim level, and model. Usually, large cars or trucks can accommodate more significant amounts of fuel.

What Is The Average Car Gas Tank Capacity Per Type?

A car gas tank capacity ranges between 12 to more than 30 gallons. Some larger car types, like large SUVs and pickup trucks, can hold up to 33.5 gallons of fuel or more.

Let’s explore the gas tank capacity for every car type alongside some examples:

  1. Sedan

How Do I Find My Car Gas Tank Size?

To find your car’s gas tank capacity, check your owner’s manual. For Ford owner’s manuals, you may find details of your car tank in the Capacities and Specifications section. 

One trick in finding your car tank details quickly is checking your manual’s index. Look up similar keywords like fuel tank, gas tank capacity, fuel tank size, and other related words and go directly to the corresponding pages. 

You can also look up your car model and specifications on the manufacturer’s website. Similarly, check out the car’s labels, as they may contain crucial information like your car tank capacity. 

While running empty is risky, and we strongly recommend against it, it’s also one way to determine your car’s gas tank capacity. 

Is a Large Gas Tank Better? 

Bigger doesn’t always mean better, and the same principle applies to gas tanks and fuel consumption. While big gas tank sizes can mean high fuel capacity and fewer trips to the gas stations, you can’t save on fuel by buying a car with a large tank.

That said, it’s essential to note the importance of your car’s fuel efficiency. Fuel efficiency refers to the energy your vehicle converts from fuel needed for performance. Therefore, increased fuel efficiency is preferred. It allows owners to cut back on fuel costs and carbon emissions. 

What Is the Disadvantage of a Large Gas Tank?

Some cars with large gas tanks may compromise on fuel efficiency, which means that despite having an extensive fuel reservoir, your car could be consuming lots of fuel to function. 

This phenomenon happens because cars with big fuel tanks tend to be heavier. According to Natural Resources Canada, when a vehicle is heavier, they have greater inertia and rolling resistance.

In effect, it burns more fuel and requires more engine power. The agency suggests purchasing a lighter vehicle with a more fuel-efficient engine. In fact, a  Massachusetts Institute of Technology study states that a 35-percent reduction in vehicle weight allows vehicle owners to save up to 20% on fuel consumption.

Meanwhile, according to the United States Environmental Protection Agency, a 10% change in the weight of a vehicle affects the fuel economy by up to 6%.

Cars With Big Gas Tanks

Here are some car models known for their large gas tank capacity:

  1. Ford Expedition EL: up to 33.5 gallons
  2. 2022 Toyota Tundra SR5: up to 32.2 gallons
  3. Ford F-250: 48 gallons
  4. Ram 2500: 50 gallons

Conclusion

Car gas tank capacities vary based on the car model, trim level, size, and type. 

Bigger cars, like SUVs and trucks, usually possess gas tanks with bigger capacities. 

Examples of vehicles with big fuel tank capacity are the 2022 Toyota Tundra SR5, Ford Expedition EL, and Ram 2500.
