All of the brands I have dealt with in the past say a quart in a thousand miles is within normal oil usage range. The design of this motor further compounds the issue and if you drive hard then oil usage will increase.
My 05 OBK 2.5XT uses quite a bit more than 1qt per 1000 miles but I haven't cared that much because it is not that expensive to add some here or there, especially when compared to a new bottom end. I also drive my vehicle pretty hard sometimes.
When I bought my car it had 114xxx miles (now 150xxx) worth of previous owners with probable extended/forgotton oil change intervals, low oil/no oil, or crap oil/filter combinations under its belt. The bottom line is it needs the oil and I love the car so in goes the oil. I just run an oil that suits my needs and wont break the bank.
Sorry for the long post.
