Hi Guys,

I hope that someone may be able to help me out.

I have an X5 E70 X5 xDrive30d SE 2009. I used to get 280 - 300 miles per tank full. My car then went into the local dealership for attention to the power steering (new hose required).
Now I only get 250 - 260 miles per tank full.
Could it be the fuel that I am using - Shell (Same Garage) or Could it be something else ?
Has anyone got any suggestions for me ?

Regards
Sanjiv
