Is that mpg measured on the trip computer? If so, then you really need to check the actual usage by brimming it, driving for a few hundred miles then brimming it again.

as above - verify the actual MPG brim-to-brim and ensure it's not just the DIS playing tricks, as it so often does.

Also, not sure if this applies in staffs but we've had a significant drop in average temps recently from 22+ to just above 10, that alone can cause a drop in MPG.

I hate winter for a variety of reasons, MPG killing being one of them.
