Engine using oil

Hi
I own a Feb 09 2.5i liberty has done nearly 60000kms mostly traveling between towns in rural NSW.
Owned the car since new and it seems to be getting worse as I noticed it was using oil around the 30000kms mark if not a bit earlier. It had its last service in August at about 52500kms and I checked the oil a month ago and noticed that it dropped to below halfway mark so took it the local subaru dealer also who I bought it off. they said as long as it stays between the high and low mark its fine and they put me on a monitoring program where i would come back in a month and get it checked.
Today I took it back again as it has been just over a month and the car has done about 1700kms since this time last month. Dealer checked the oil and saw that it had dropped to nearly the low line but the more we left it to cool down the lower it got and after about 15 mins of cooling down it dropped to below the low mark. Head service advisor said that the engine takes about 1 litre of oil and will use that same amount every 10000kms also a subaru standard apparently. So it was filled with 750ml of oil which brought to around the 3/4 mark.
Just wondering what anybody elses thoughts on this situation is or if anybody else is or has been through this.
Thanks in advance
