Hi there, I have just bought a 2009 X3 2.0 D and I am only getting 23 - 27mpg I am extremely surprised at this as K used to get 35-40mpg driving locally in my Audi A5 3.0 TDi I believe I should be getting 40-45mpg. Previous owner has fitted 19" wheels so not sure if this may be contributing, but i'm fairly sure they can't be the complete problem Any ideas please or I think I am going to have to sell it which would be a shame as I like driving it!

I have bought a 2009 X3 2.0 D and the first tank I got less than 23mpg the 2nd tank 27mpg. The previous owner put 19" wheels on it, somebody suggested that was why? I can't believe that would cause such a massively low mpg, any suggestions please?
