"Full-to-empty has become the latest and sneakiest device used by hire-car firms to boost revenues," said Miles Brignall, the Guardian's consumer champion. "Several firms now do it, knowing it is impossible to return a car with no fuel. It particularly hits those who don't use the car much during the week, and have to return it half full."

Let us know if you've been wrongly charged by a car hire company or feel you have been treated unfairly. Let's stamp out these underhand practices once and for all.
