I get about this in my manual on my 50 mile round trip commute. Mostly dual carriageway.

If you are reading form the IPK display, ignore it until you do a brim to brim calculation. They are notoriously inaccurate.
If you did this using brim to brim calculations, and you had some town driving also, it is an auto, then I would be expecting 37 - 45 depending on temps, driving conditions, journey etc. Check the coolant temp using the OBD display.

This is using "brim to brim" method, which is the way I've always done it as I learnt a long time ago that the digital readouts are not very accurate when I got my Saab 93 back in 2001. |

my manual varies between 32mpg to 48mpg depending on my right foot on a 90 mile run up the M6, thats the top end of the M6 so very little traffic

Hi Spencer. If I was only getting that on a journey of that sort, I would be looking for a diesel leak, cold /warm weather. Is it down on power generally? I would be looking for Maf faults, or perhaps you use the loud pedal all the time?
