Hertz has 615k cars. If only 10% of those rentals result in a fuel overcharge of 5 gallons it would be a substantial sum of money. If the overcharge occurs when a car is returned empty when it should have been returned full, Hertz charge $9.99 per gallon of fuel. I don't know what they charge if you buy the non-existent fuel at the get go.
