BBC NEWS | UK | England | London | Drivers begin chip fat fuel rally

Cars powered only by chip fat and cooking oil are setting off on a two-week rally from London to Greece.
Competitors must not use conventional petrol or diesel, so are relying on waste cooking oil from restaurants and bars they come across on the way.
We should do that here! Sydney to Perth anyone?
