2002 Deville bought is used with 46,000 miles after driving it 1,500 miles I noticed it used 3 quarts of oil. Everyone I ask says it is excessive and I agree I can not get this taken care of on my own and I owe too much money on the car to get rid of it. Cadillac should fix this problem I have talked to other individuals and they had the same problem with one car having blown the engine. He now drives a Toyota avalon.
