Frequently Asked Questions

How do I calculate my car's MPG?

Fill your tank, reset your trip odometer, and drive normally. At your next fill-up, divide the miles driven by the gallons needed to refill. For example, 300 miles driven on 12 gallons equals 25 MPG.

What is good gas mileage?

Good gas mileage varies by vehicle type. Compact cars should get 30-40 MPG, midsize sedans 25-35 MPG, SUVs 20-30 MPG, and trucks 15-25 MPG. Hybrids typically achieve 40-60 MPG in combined driving.

How much should I budget for a road trip?

Budget $100-150 per person per day for a moderate road trip, including gas, lodging, food, and entertainment. A family of four on a 5-day trip covering 1,000 miles might spend $800-1,200. Costs vary significantly based on route, accommodation choices, and dining preferences.

Is a road trip cheaper than flying?

For solo travelers, flying is often cheaper for distances over 500 miles. For families or groups of 3+, road trips are usually more economical because you split one set of costs. Factor in baggage fees, rental cars, and the value of your time when comparing.
