Ours uses about 8 quarts in between oil changes (every 3,500 miles). I call it Extremely excessive oil consumption :) Does not drip any oil nor does it smoke, just drinks it.

Since purchase of car, engine uses large amount of oil. Must check oil stick to make sure engine has enough. This problem should have been recalled to be fixed a long time ago. Shame on Cadillac DTS 2000 model.

common problem. I'm told that adding new oil between oil changes actually helps prolong engine life as the oil doesn't get as dirty as it would normally get between changes.

I had 3 of 4 window regulators go out within a month of purchase (used). Beautiful car, but it also guzzled oil like it was going out of style. I read the posts and have done the following: every now and then I stomp it real good for a brief run to clean out the carbon. I use Chevron Techron additive every few tanks and switched from cheaper gas to Chevron (with Techron. I have no stock in Chevron, but for weeks now the car hasn't used a drop of oil (thank goodness!). Keeping an eye on it and haven't taken any real freeway trips, but around town, no oil usage. Each car may be different, but I am happier now.

I just recently purchased this car and it had 76,000 plus miles and I noticed the check the oil dipstick warning came on and it was approx. a quart low. I have since added another quart at 78,000 miles. I will drive another 112 miles today and if it need oil again I'll return it back to the dealer for a refund.

My 99 DeVille uses about a quart every 2000 miles. Was using allot more but during a recent head gasket repair I had all the gaskets and seals changed including the oil pan, timing chain, and valve covers. I am going to look into this "ring wiper" issue.
