I own a 2002 deville and my expeiance with oil consumption has been a nightmare. I have 40000 mi. on my caddy and have been using 3 quarts plus in less than 3000 miles. I could write 8 pages of stuff to you all but here is the end results. 2002 and several other caddy's had a test engine installed. No you wont see any oil on your floor nor will you see an blue oil trail out of your exhast unless you floor it. My caddy is at the dealer as I speak getting new pistons and rings. I went through a 3000 mile oil consumption test and finally caddilac said to bring it in. there is a bulletin on this vehicle but not a recall. I might add that I am also out of warrentee and caddilac is installing this for free and gave me a loaner. Do not back down when you are messing with your dealer about this! In my eyes caddilac has owned responsibility and there needs to be a recall for us! besides the stress that I have went through I feel caddy is doing right.
