I've had the 2013 DS5 2.0hdi 163 for roughly 18 months
I'm running the 18" wheels (this matters because using the 16" wheels can lower fuel consumption considerably).
My most common use case is driving around town, with the weekly short motorway trip to facilitate DPF regeneration.
Overall mileage is at 41mpg.

According to my experience, it is easy to do well over 60mpg in the motorway.
In town, hard to do much better than 38mpg for my commute.
I've started trying shell vpower to see if it made any noticeable difference, and it kind of did as some engine stuttering in specific conditions is almost gone.
Fuel consumption seems slightly better but not really relevant.
