Id agree with the petrol comment plus they warm up quicker and you don't have to worry about residuals as such!
Doing 9k per year at £1.25/l (Derv / Super Unleaded):
Diesel @ 55mpg = 164 Gals/Year = 744l = £930
Petrol @ 35mpg = 257 Gals/Year = 1169l = £1461
£44/Month Difference. And you'd have to visit a petrol station 7 more times a year
