Estimating Gas Needed for the Trip

To estimate how much gas you'll need, you should know your vehicle's fuel efficiency and the total miles you'll drive.

Most cars average between 25 and 30 miles per gallon (mpg). Here's how to calculate your gas needs:

• Divide the total miles (330) by your car's mpg. For example, 330 ÷ 30 mpg = 11 gallons.

• If your car gets 25 mpg, 330 ÷ 25 = 13.2 gallons.

• Consider extra miles for detours or local driving once you arrive.

So, expect to use between 11 and 14 gallons of gas for a one-way trip.

Current Gas Prices and Total Fuel Cost

Gas prices vary by region and time, but as of 2026, the average price per gallon in the Southeast U.S. is around $3.50.

Using this average, here’s an estimate of your fuel cost:

• At 11 gallons: 11 × $3.50 = $38.50

• At 14 gallons: 14 × $3.50 = $49.00

Keep in mind prices can be higher near cities or tourist areas. Checking apps like GasBuddy before your trip can help you find cheaper stations along the way.
