let me see... 52 weeks in a year.. with 650 miles a week.. thats...33800 miles a year... minus 9 public holidays and 25 days leave should leave me with 29380 miles a year.
@130miles per 11 litres or £9.12 of petrol (.829 ppl) works out at 2486 litres or
£2060.894 a year.
So 546.84 ukGallons is
53.7 miles a gallon over the year.
woo hoo.. math...
