S40 (New) Engine 2.0D : Fuel consumption issue,300 mile tank range

Firstly, let me say that this is in the WRONG message prefix, but there is no category for 1.6 engine (diesel too).
Problem: assuming 10 gallon tank capacity, then im getting 30 M.P.G, from my 06 reg volvo s40 1.6 SE. It is fair to say that it does spend some time in traffic,but probably less than a quarter of its running time. You dont expect fuel economy like this from a diesel, and im seriously, seriously p*ssed off, especially after reading the OFFICIAL fuel economy figures Volvo are lying (ERR SORRY I MEANT ADVERTISING!!) about.

I'm really, genuinely surpised at such a low figure, and if its not too much trouble, would anyone else with the same car mail me to sort out some similar fuel consumption tests (Full to empty) Hell, I'd be so glad of the cooperation I'd even pay you to do it,lol.

Here endeth the lesson, but to recap ,any comments or people with the 1.6 diesel, I would be happy to hear from you, all (or am i the sole muppet to buy a 1.6 diesel on this site, or probably any other, the world, or anywhere else

Thank you one and or all depending on how many people read this post.
