Hi i have a 2000 w reg Kia Shuma 1.5, i got it about 5 months ago and the fuel economy wasn't all that great! but over the past few weeks the fuel consumption has gone way way down even though the fuel price at the garage i go to has stayed the same. i put £10 a time in now and i used to get about 50/55 miles from it, now i only get max of 30 miles from £10 at £1.36 per ltr

i have had a look around online but cant find anything that would suggest such a rise in fuel consumption

many thanks Darren
