    Works out at about 33.5mpg. Sounds low but depends on many things.

    DPF regens?

    Lead boots?

    Heavy use of aircon?

    Carrying lots of stuff in the boot, or full load of passengers?

    Heading into a strong headwind or up a lot of gradients?

    Were you 'pressing on' at 80-90mph?

    How long have you had the car and how long has it been giving alleged poor mpg?

    How does it compare to previous cars?

      That's about 32.8 mpg. How hard are you driving it. That's at £1.32 lt.

        Have you checked the tyre pressures? That seems to make a lot of difference
