Renter is responsible for putting the vehicle's fuel to the same level or better in fuel as when received. Penalty fees will apply should the vehicle be returned with less fuel than when given to customer. Penalty fees can run as much as $40 administrative fee and $6.50 per gallon or higher. Please avoid these unnecessary fees by returning the vehicle with the appropriate amount of fuel.
