My dCi 130 is only up to 6000 miles, so I'm still hoping that it'll loosen up a bit. It seems to be getting a little bit more life into it (or I'm just getting used to the turbo lag, having only had normally aspirated petrol engined cars before) but fuel economy doesn't seem to be improving.

If I don't bother to reset the trip counter and drive normally (which for me means using most of the useful rev range, and foot to the floor every now and again) it tends to average out at around 35-38mpg. That's mostly motorway miles, mind you - I'm sure it'd be a lot worse around town.

On a free-flowing motorway, with cruise set to 80, it'll generally return about 42mpg in 6th gear. Considering that my 1995 2.0 petrol Laguna would manage around 38mpg in similar conditions, I think that's pretty poor for a diesel. On the other hand, it's better than the very low 30's that my previous 2.0 IDE would do.
