Car hire fuel “rip offs” in Spain have come under fire from Which? The watchdog organisation has teamed up with Spanish consumer group OCU to demand companies charge fair prices in line with those available at local garages – and stop requiring customers to pay for a full tank when they drive off – and failing to refund them for unused fuel when they return the car. Six out of 10 Which? Members said this so called “full-empty” policy was the only option available to them and 72% thought they had paid prices higher than those at local garages. Which? says that in many cases travellers hit by this practice are unable to use a tankful. Someone hiring a Fiat 500 in Mallorca, for example, would need to make the round trip from Palma airport to Puerto Pollenca nearly seven times. It commends Alamo, Enterpriseand AutoReisen for operating a full-full policy, where customers are asked to return the car full so they don’t pay for unused fuel.
