How many gallons of gas does a car hold?

A standard car holds up to 15 gallons of gas, but it really depends on the make and model of the vehicle. For example, a 2019 Honda Civic has a fuel tank capacity of 12.4 gallons. On the other hand, some larger cars, like the 2019 Ford Explorer, have a fuel tank capacity of 20.9 gallons. But it's not just about the size of the car--it also has to do with how fuel efficient it is. A car that gets better gas mileage will obviously need less fuel to travel the same distance as a car with worse gas mileage.
