Compare annual fuel cost of a diesel and a gasoline vehicle.
Each vehicle's yearly cost is its fuel burn times its fuel price. Diesel usually prices higher per gallon but often sips less per mile. Lower diesel consumption can offset a higher pump price, so only a full annual comparison shows which drivetrain truly saves money.
