* Vehicle: Different cars, trucks, and SUVs have different sized fuel tanks and different fuel efficiencies. A small, fuel-efficient car will go much farther than a large truck.
* Driving style: Aggressive acceleration and braking, high speeds, and idling will significantly reduce your gas mileage.
* Terrain: Driving uphill, in stop-and-go traffic, or on rough roads reduces fuel economy.
* Road conditions: Headwinds and even tire pressure can impact your mileage.
* Vehicle condition: Properly maintained vehicles generally get better gas mileage.
There's no single answer to your question. To find out how many miles *your* car can go on one tank, you'll need to check your owner's manual for the fuel tank capacity and the EPA estimated fuel economy (miles per gallon). Then, multiply the fuel tank capacity (in gallons) by the MPG rating. Keep in mind that this is an *estimate*, and real-world driving will likely result in a lower number. The best way to know for sure is to fill your tank completely, drive until it's nearly empty, and then calculate your actual mileage.
