Question 1

How do I calculate my actual fuel efficiency?

Accepted Answer

Fill your tank, note the odometer reading. At the next fill-up, divide the miles driven by gallons added. Repeat for several fill-ups to get an accurate average.

Question 2

Is driving cheaper than flying?

Accepted Answer

For solo travelers, flying is usually cheaper for distances over 300 miles. But for families or groups, driving wins due to cost sharing. Don't forget to factor in time and fatigue.

Question 3

How can I save on trip costs?

Accepted Answer

Drive at economic speed (55-65 mph), maintain tire pressure, avoid aggressive acceleration, remove excess cargo, and use apps to find the cheapest gas stations.

Question 4

Should I add costs other than fuel?

Accepted Answer

Yes, for a complete estimate add: toll fees, parking, vehicle depreciation (about $0.10-0.20/mile), and extra maintenance for long trips.
