As if gas prices did not put enough of a strain on us during this past summer, rental car customers who decided not to prepay for fuel & don’t return their vehicles with a full tank, paid almost double the current cost of gas. A USA Today survey found that major rental car companies at 10 airports across the country charged gas at prices ranging from $6 to over $8 per gallon to refuel. At $8 per gallon, having the car rental company fill up a midsize car can add more than $145 to your final bill.
Many car rental companies do give an option to pre-pay gas when you pick up your vehicle which will save you money, but the most affordable solution is to fill up before returning the car.
