I wanted to update the forum on my oil consumption problem. Remember also that I am in Canada not the US and so as Sarah has pointed out to me, I need to look to GM Canada for resolution. The last time I posted my Cadillac dealer took the car for 3 days in December 2011 and replaced "LT CAMSHAFT COV RPL" and the workorder quoted "Part number 12641261.
Well flash forward to a few weeks ago when I had put on about 2900 kilometers and checked the dipstick and it was almost dry. No oil was in the hashed section of the dipstick. I immediately took the car into the Cadillac dealer. They started me on an oil consumption monitoring routine where I have to take the car into them (no appointment required) every 1000 kilometers. They will measure and record how much oil is needed.
Well today my car was at 920 km, so I dropped by the dealer. He added half a litre of oil, and recorded the numbers on my oil consumption chart. The mechanic also confirmed that GM Canada also sees more than 0.946 litres of oil per 3200 kilometers as excessive oil consumption. So I have to have at least one and perhaps two more 1000 kilometer "readings" before a decision is made. My vehicle is a 2005 CTS with 99,700 kilometers on it (about 62k miles). I asked what the remedy would be, and the tech said there were a number of possibles including dismantling the engine to gauge the piston clearances, or possible replacing the entire engine.

Insist on a new engine. If they do not concur, then go see a lawyer and advise them you'll sue. That will get their attention.

Just wondering how things are going now that you are using Castrol GTx. Is the oil not being consumed as much? How did you go about transitioning from synthetic to conventional oil?
Also, would like to know if anyone else has tried this.
Note: I have a 2007 2.6 V6 and have received a 10 year warranty from GM on the timing chain, also did the recall which consisted of re-calibrating the oil change intervals system.
I am experiencing similar problems with going through 1.3 quarts every 2000 miles.

You should check with your dealer before switching types of oil. I am in Canada and my dealer told me that if I did not continue to use synthetic it would void my warranty, so I will continue to use synthetic (even though it costs about $17 per litre and my oil changes cost around $150)

If you live near the U.S. border, buy the synthetic oil in the U.S . and bring it to the dealership when you have the oil changed. It will save you some $. Four U.S. quarts of Mobil 1 costs about $35 U.S. at Walmart.

Same issue here...
My wife and I have a 2009 CTS4 with the base V6 engine. We bought the car new in August 2009. It currently has approximately 24,000 miles on it. It has been about 6,000 miles since the last oil change (always synthetic). While driving the car Wednesday, it felt like it had a problem with the transmission or torque converter. It felt like the trans was slipping and there was a decent amount of noise. The next day I called Cadillac they said to bring it in. We stopped driving the car and brought it in today. Since it was coming up for an oil change IMO (OLM said 49% remaining), I agreed to have them do an oil change while the car was there. This afternoon we got a call that the engine was 3.5 - 4 quarts low on oil. Note that the previous oil changes did not indicate abnormal consumption (at least it was not noted to me). The noise was assigned to the timing chain and the timing chain will be replaced. I was told that actually low oil sometimes voids the warranty but that the dealer will fix the timing chain. Nothing else has been noted yet as an issue. I'm concerned about several things now. Mainly that the dealer is fixing the timing chain but also voiding the warranty for the engine. Although I'm not having issues with the dealer yet, I can almost smell it coming. My wife and I sold 2 BMW's and picked up two GM cars during the recession - mainly to support the American economy. I really hope not to regret this decision. Has anyone here had issues with the warranty being voided after bringing the car into the dealership with low oil?
Thanks in advance for any feedback.

The warranty was expired on my 2005 CTS, although I did call Cadillac and GM only to be told there is nothing we can (Will) do for you. I ended up purchasing a rebuilt 3.6.
Dump the Caddy NOW! I will never by another GM! I actually love the looks of the new Camaro....but despise the customer service or lack of customer service.
Read all the comments in this thread, it will help you understand why CTS owners are so upset!

Get rid of the car that is the best thing to do , while it still has warranty on it I have a 2004 CTS and I have had my timing chains and heads replaced the differential has had issues and the front wiring harness replaced and it uses 1 quart every 1000 miles, it appears the issues are still there 5 years later. I have bought 2 Toyotas one has 40k and the other 100k and neither have required any repairs so far I would get rid of the cady but as you will find out it has very low resale. Good luck. I think more Canadians and Americans at home are employed by foreign car manufacturers then GM so I would not be to concerned about saving jobs in NA.
