That's definitely the worst consumption I've heard of. How many miles on the car?

57000

Did this come on suddenly?

No. It's came on a few times in the last 6 month

That would be considered excessive for sure.

No. It's came on a few times in the last 6 month

So, it's been drinking oil at that rate for at least 6 months?

Yep. Its not burning or leaking it

Let me ask a stupid question.

How many quarts are you putting in when you change your oil?

6 quarts

Ok, just making sure. When I first bought my car(back in 07) I argued with a guy at a parts store for 10min about how many quarts the car took. He was insistent that it was 4.

Mine was pretty bad when I first bought it. 1000-1500 after I bought it there wasn't any oil on the dipstick. Changed it with synthetic and tuned out DOD, and not a issue anymore.

Are you still under a warranty? There is an updated oil consumption TSB. If you follow the recommendations of the TSB you should be able to remedy this.

And if your not under warranty you could try a tune with dod delete.
