Common practice among car rental companies in the U.S. is to deliver the rental vehicle with a full tank of fuel to the renter. At the time of making the reservation the customer will have the option of selecting a rental plan that already includes the first tank of fuel; therefore, the customer will be allowed to return the vehicle with any amount of fuel at no additional cost. Upon delivery of the rental vehicle the client will also have the option to either prepay for the first tank of fuel, and not have to worry about refueling before return, or to refuel at a gas station of choice before returning the vehicle. If none of the three options is selected, the rental car company will charge the renter for the cost of the missing fuel plus a refueling service charge.
