Is my Citroen Picasso supposed to be so slow?

I've bought a Citroen Picasso 1.6HDI for taxi driving. I've been driving it for a week now and noticed that it seems to lack power when accelerating. I had it loaded with four passengers and luggage and it struggled, especially on hills. Is there possibly something wrong with it, or is this car underpowered? It's 04 reg and has done 90,000 miles. I can't get it to go much above 70mph.

First take out the air filter and see if it goes properly then, if it does, junk the old air filter and fit a new one. If it doesn't you could have a turbo problem or a DPF problem. The turbo might not be functioning, or the DPF might be blocked. DPFs with the 1.6HDI 110 only last 80k - 120k anyway.

Please can you tell me how often should I get the oil and oil filter changed on my 2003 Peugeot 206 SW? Should I get the air filter done at the same time?
