Hello. I am wanting to buy a Focus ST, can afford the car and the insurance but I was just wondering what it was like for consuming petrol? I do about 1000 miles a month with about two thirds of this being motorway driving. Could anyone give me an idea of roughly how many times Im going to have to fill the tank a month, I know you are meant to get 30 mpg combined but I was just wondering if it was in reality a bit higher or lower than this. Any help is appreciated.
