#1 of 158 Which is ok for 6cyl. cts--Synthectic or real oil?
Apr 15, 2007 (12:08 pm)
I use regular oil not synthectic. Do I still go by the computer to change oil? 2006 cts.

the GMOL indicator was designed to work with the factory installed oil......did it come with dino or synth?...you can actually use the GMOL to monitor your oil change intervals....just dont exceed intervals shown in your owners manual....I use full synth in my 04 Malibu Maxx LT..watch the GMOL..and change at 7500 miles of %25 remaining on the GMOL..whichever I reach first......91K on my Maxx and no problems at all
#3 of 158 2004 CTS oil dipstick reading
Sep 05, 2007 (9:08 am)
Stupid question I know.
I have a 2004 CTS 3.6L V6 when I check the oil level I get a low reading below the 3 bubbles on the stick. I have no blue smoke to indicate Iím burning oil. And no oil leaks that I can see. Anyone else have this problem when checking their oil? Even after adding oil it's still below the 3 bubbles. Something else I should check?
Is there a low oil level sensor on the 2004?
Thanks in advance

I'm pretty sure the 3.6L VVT on the CTS is synthetic only.
#5 of 158 Shudder at about 42 mph
Sep 28, 2007 (10:53 am)
Anybody ever had a mild shudder develop under light throttle, in 4th gear (automatic) at about 1600 rpm and about 42mph? It only does it in this narrow range. Our 2005 CTS with the 3.6L V6 has started to do this pretty consistently. It has 24,000 miles. Possibly the rear axle issue? Never had any problems with the car in 2-1/2 years.

Is the 95 STS antenna mast available without changing the whole unit?
#7 of 158 oil life monitor
Nov 12, 2007 (4:55 pm)
Took my 2004 Cadillac cts to the dealer today.
To make a long story short..
The Cadillac dealer service department told me today. The oil life monitor is a bad tool to use when deciding oil changing intervals. I had my oil changed 5000 miles ago. Oil life monitor indicated oil life 69%. I figured I could go at lest another 3500 miles before the next oil change. Not according to the dealer service advisor and an technician they advised me 3500miles regardless, the oil life monitor goes by the engines rpm and temperature and is only ruff yes I quote a ruff guide. I asked what the hell the oil life monitor is doing on GM vehicles and why GM is telling me different story. They had no answer, I said Amazing and left!
Any of you on this forum been told this about the olm? I contacted GM, They stand behind the olm and suggested I continue to use the olm to service the vehicle. Yes I used the recommended Mobil 1 5W30 synthetic. And I will not return to this dealership again. Thank you in advanced.

I think your dealership is simply trying to get more $$ from you by bringing it back in more often than required......The OLM is standard in most GM cars today....look at the owners manual.....it doesnt give you a standard oil change interval any more...but references the OLM system....I use mine as my oil change interval..usually taking it down to 25%....using Mobil 1...in my 04 Malibu and 06 Solstice..getting about 7500 miles between changes.......3K changes are a personal choice...but a waste IMHO.....
I would go to another dealership.....

I agree 100% I thought the same thing.
#10 of 158 2005 Cadillac CTS- Engine problem
Nov 13, 2007 (7:48 am)
About two weeks ago my CTS started making this knocking noise when I would turn it on, after a few seconds it would go away. Then last week when my husband was driving it the knocking noise turned into a rattle (metal on metal) noise, while we were stopped and moving- the faster we were going the faster the rattle. We did not make it more than a mile until the check engine light came on and we parked it and had it towed to the cadillac dealer. The oil had just been changed a week prior to the noise starting (synthetic), and another oil change had been performed about 3 months after buying it. The car is used with 30k on it when bought and now, 10 months later 43k. The dealership wants proof of two oil changes since bought which we gave them, and $4600 to tear apart/ put back together the engine to see if it is a manufactory defect or poor maintence. If it turns out to be a engine defect then the warranty will come into play, if not we are SOL. The service department is telling me they have never seen this before and that these engines run perfect with the correct maintence. They cannot tell me what is exactly wrong with the car but are pointing the finger at me and saying that there was not enough oil to lubricate the engine and in turn my engine blew. They are telling me there is metal in the oil, and that it is sludge. You should also know the oil indicator was taken out when a after market nav was put into the car, but they say that it should only have needed two oil changes since being bought. I am curious to know if anyone else has been in this situation or thinks that it is a manufactory defect or not. I am having a hard time risking $4600....
