Owners Cars - "The good thing about this company is that they give you a full tank of fuel and you return it with a full tank of fuel. "
This not quite uptodate ( just came back having hired a car from them last week )
The late 2011/2012 policy is (also on website )
Our prices do not include fuel.For rentals of 4 or more days, cars are supplied with ½ tank of fuel to travel and cars have to be returned empty; there is no refund for unused fuel. Remember that the amount is added to the price indicated during booking when the car is picked up. The price will depend on the type of fuel and tank capacity on each car model.For rentals of 4 or less days, the car can be returned with the same amount of fuel as it had when it was picked up"
-so you don't know what you actually paid litre wise
GIven the petrol price increase the bigger firms are operating a similar policy to the above
