Gas is not reimbursable if mileage is being claimed. Also, a gas reimbursement would be limited to the calculated mileage amount in the event the gas cost is more than the mileage calculation. When renting a vehicle, it is recommended to use the travel card for the gas purchases. Most rental car vendors require the car to be returned with the same level of gas as it was at the time of pickup. If not, they will charge an inflated amount per gallon to fill up the car or return it to the level it was at the time of pickup. So, to save money it is recommended that the gas be purchased by the traveler prior to returning the vehicle.
