On average, a typical passenger car in the United States consumes around 500 gallons of gasoline per year. This is based on an average fuel efficiency of 25 miles per gallon (mpg) and an average annual mileage of 12,500 miles.
However, fuel consumption can vary significantly from car to car and from driver to driver. For example, a car that gets 30 mpg will use less fuel than a car that gets 20 mpg, and a driver who travels mostly in city traffic will use more fuel than a driver who travels mostly on highways.
To estimate how much fuel your car will use in a year, you can use the following formula:
```
Fuel consumption (gallons) = (Annual mileage / MPG)
```
For example, if your car gets 25 mpg and you drive 15,000 miles per year, your car will use approximately 600 gallons of gasoline in a year.
It's important to note that this is just an estimate, and your actual fuel consumption may vary.
