engine oil usage

Hi, I have now done 10000 miles in my new van (180) I've now put in a total of 4 litres of oil!!! My dealer says it's normal to use 1 litre per 1000 miles!!! (Oil ain't cheap anymore!) Is this right? I also have a very annoying vibration that I think is coming from the small box compartment on...

silly question , but I can’t Sean to find out what is the correct oil to put in the engine, could somebody please advise me as I need to put some in now?

Has anyone else had an oil warning light come on? Just had the oil warning light come on and done a check. The oil is right at the bottom of the stick. Anyone else used much? It's a 204ps with 6,000 miles.
