Two problems related to engine burning oil have been reported for the 1999 Cadillac Deville. The most recently reported issues are listed below.
Excessive oil consumption. Starting from 26 Jun. 1999 ,the day after purchase, till 20 Mar. 2000 the dealer worked on finding and correcting engine oil leaks. With the next oil change, after correction of the oil leaks , on 12 Jul. 2000 the oil level was down one quart. At this time I requested an oil consumption test which was completed(3k miles later) on 5 Sep. 2000 and again was one quart low. At this time I was informed that they would now have to do a formal consumption test(3k miles more) to submit to g. M. Should the oil level again be a quart low the dealer advised me that it would be with-in acceptable limits in accordance with the latest g. M. Bulletin,which was not available for me to see. I subsequently called g. M. At 1 800 458 8006 and they informed me that they could not make any commet on this "technical" problem and that I would have to work it out with the dealer. . Would I be way off base thinking that the dealer more or less already stated he is not going to do anything about this????? thanks for your ear.
High oil consumption. Refer;odi # 730667,secound 3k mile oil consumption test compeleted and again over a qt. Used. Dealer would/could not take any action because manufactures bulletin (id># 502869 guide#76-60-04a )states 1 qt. Consumption in 2k is normal,also; in a e-mail response to this cosumption question mr. Jack anderson (g. M. Spokesmen) stated "oil consumption of two quuarts per 3000 miles is not adnormal". I am not questioning g. M. Is why was this information on the window sticker right next to the fuel economy and annual fuel cost. Also,if it can burn two qts. Of oil when new how many qts. Will it be burning at 50k miles. Is this in keeping with the high standards of air quality the epa is trying to maintain? thanks for your time. Ra.
