Divide your total trip distance by your vehicle's MPG to get gallons needed, then multiply by the price per gallon. For example, a 400-mile trip at 25 MPG with gas at $3.50/gal costs 400/25 x $3.50 = $56.
What is the average fuel efficiency of a car?
The average fuel efficiency for new cars in the US is about 25-30 MPG. Hybrid vehicles average 45-55 MPG, while SUVs and trucks typically get 18-25 MPG.
