Im from England, born and bred.
My Duratec Mondeo 2.5l V6 usually gets around 280 - 300 miles (if Im very lucky) from a full tank (61 Litres - approx 15 gall). Combined average is around 23MPG. Theres nothing you can do fellas!
When you feel down about it, just think of me paying the equivalent of $6.50 a gallon!!!!!!!!!!!!!!! We are the highest taxed country in the world. England sucks!!!!!!!!!!!!!!!
