How do you work it out? I'm hiring a car at Christmas, don't want to put too much fuel in.If you keep a note of the miles you've done its not.difficult to make a reasonable guess about how much juice you've supped. Even easier if the car has an OBC which records fuel.consumption.
In our case, it's Asda so cheap fuel and about a mile away.That would depend on how close the petrol station is.
+1Our local car hire place sends you out with a full tank and expects it back with a full tank. Nice and easy that,
Did you find yourself tempted to try siphoning it out to give it away?
