Car burning alot of oil

What might the problem be if my car is constantly out of oil and there is no oil leak? I took it to a repair shop that said there wasn't a leak, but I had an oil change about 3 weeks ago and now it is bone dry. I can put oil in myself and a week later it is dry again. I have a 2002 Cadillac Deville DHS with 66,896 miles and a v6 engine. Please assist.

They dont make a v6 for devilles all are north stars v8. You need to take it to the dealer and let them soak the cylinders with a chemical to free up piston rings may have to do this a couple times. They are stuck
