Frequently asked questions
How do I calculate gas cost for a road trip?
Divide your total miles by your car's MPG to get gallons needed, then multiply by the gas price per gallon. Example: 600 miles ÷ 32 MPG = 18.75 gallons × $3.50 = $65.63. Don't forget to multiply by 2 for a round trip.
How do I find my car's actual MPG?
The most accurate way: fill up your tank completely, reset your trip odometer, drive normally until nearly empty, then fill up again. Divide the miles driven by the gallons it took to refill. You can also check the EPA fuel economy rating for your vehicle at fueleconomy.gov — but real-world driving often differs from EPA estimates by 10–20%.
How can I save money on gas for a road trip?
Key strategies: maintain proper tire pressure, remove excess weight from your vehicle, use cruise control on highways, avoid idling, plan your route to avoid traffic, use gas price apps to find cheaper fuel along your route, and avoid premium fuel if your car only requires regular.
Is driving cheaper than flying for a road trip?
For solo travelers, flying is often cheaper for longer distances. For 2 or more people sharing a car, driving often wins because you split the gas cost. Other factors include travel time, bag fees, flexibility, and whether you need a rental car at the destination.
