How it works and what it leaves out
- Gas used = distance ÷ fuel economy. Cost = gas used × price per gallon.
- The default price is EIA's weekly average for regular gasoline in the area you pick, including taxes. Stations near you may charge more or less; type your own price if you know it.
- Real fuel economy depends on speed, traffic, weather and load, so treat the result as an estimate.
- It covers fuel only: no tolls, parking, insurance, maintenance or wear on the car.
