Report: Excessive Engine Oil Consumption
Cadillac DeVille Problem
Model Years Affected: 1996, 1997, 1998, 1999, 2000, 2001, 2002, 2003
Average Mileage: 95,007 mi (34,000 mi - 170,000 mi)
Vehicles equipped with the 4.6L engine may develop excessive oil consumption. Please be advised that under optimum driving conditions, using one quart of oil every 2000 miles is acceptable. This Cadillac standard applies to vehicles with less that 50,000 miles. Our technicians tell us that if you experience excessive oil consumption it may be caused by built up on the piston rings which restricts movement, preventing them from wiping all the oil from the cylinder walls. Oil left behind is then burned during the combustion process. There is a special ring cleaning procedure which can help this situation. The GM service bulletin number is #02-06-01-009C.

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.

RookieI 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.

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.

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.
