Travel Deal of the Day (December 31, 2007)

With fuel over $3/gallon, it can be quite expensive to fill a rental car’s fuel tank. Hertz has an offer for free gas to lower the total cost of a car rental and to help deal with the high cost of fuel.

The Deal:
Get a free tank of gas when renting a Hertz car for at least three days. The offer applies for cars picked up by January 18, 2008. The deal applies even for the most reasonably priced "economy" class cars.

How:
Go to the Hertz Free Gas Deal.

The Inside Scoop:
The value of this coupon varies based on how "empty" your fuel tank is when you return the car. If you return the car on "empty" and the car holds around 15 to 18 gallons, this coupon is probably worth around $50, which is an excellent discount for a three day rental.
