The average fuel efficiency for a car is around 25 miles per gallon. This means that you will need approximately 20 gallons of gas to make the trip.
The average price for gas in the United States is around $3.50 per gallon. This means that you can expect to spend around $70 on gas for the trip from DC to Charlotte.
However, gas prices can vary significantly from state to state and even from gas station to gas station. It's always a good idea to check current gas prices before you make your trip.
Here are some tips for saving money on gas:
- Drive at a steady speed. Rapid acceleration and deceleration can waste gas.
- Avoid idling. If you're going to be stopped for more than a minute, turn off your engine.
- Keep your tires properly inflated. Underinflated tires can reduce fuel efficiency.
- Use cruise control on the highway. This will help you maintain a steady speed and save gas.
- Compare gas prices before you fill up. You can use a gas price comparison app or website to find the best prices in your area.
