Formula
Fuel needed = distance / MPG. Trip fuel cost = fuel needed x fuel price per gallon.
Example
A 300 mile trip at 30 MPG uses about 10 gallons. At 3.50 per gallon, the fuel cost is about 35.
Common mistake
Real trips can use more fuel because of traffic, hills, weather, tire pressure, cargo weight and detours.
