I use Amsoil 0W-30 in my CTS for 3 yrs and I have it in my 2008 GMC. Been using it for many years. I change oil once a year which had been about how long the OCM lasts, between 7000-10000 miles. So far I have not used 1 drop of oil. I also changed the differential to Amsoil and the trans fluid.

Btw - I started using Amsoil back in 1975.....

One other oil may work well for you. Pennzoil Platinum Synthetic. And this is coming from an Amsoil guy, me. Running it in my 07 nowl Autozone had a BOGO deal and I jumped on it. Bitog has had a numer of reports on this oil and it is doing very well.
Good luck.

As long as the GM specs in your owner's manual are followed you're good. Mobel 1, Royal Purple, AMSOIL, Pennzoil and several other synthetic brands all meet the GM Specs for my engine. The one that goes on Sale is the winner! Condums are optional..

lol true, the 1 on sale is the winner...lol
i wait for a good synthetic to go on sale and buy enough for 2 changes..then i dont have to worry about being late or missing a sale.

My garage current has 2 five quarts of 10W30 containers for the truck and SUV and I have a case of 24 quarts 5W30 for the Caddy and Tbird, all synthetic. Every time I change I start looking for sales. Oh and BTW, don't get your oil from an automotive parts store as the prices are wacked. I get mine from Wally Mart and eBay (when I can find it free shipping) and save $8.00 to $10.00 a change. I've been also thinking about doing the 5 gallon container but I'm not too sure I can left it anymore.

Usually when something goes on sales its because its been sitting on the shelf for a while. Seems to me some waste a lot of time shopping for deals. You end up spending a dime to save a nickel. Or you end up buying some other crap you would have never bought had you not gone to WM to buy the oil on sale.

I buy a a case a yr and done with it. Every fall I order a case of Amsoil SSO 0W-30 and 2 oil filters (08 GMC & 05 CTS), 3-5 days later the UPS guys drops it off and I can forget about it for another year.

I've only run M1 in my CTS & I don't have any complaints, but it was just the opposite in my Camaro. It drank M1 like I drink Captain & Coke (as fast as I can get it until it's all gone) so I switched to Amsoil & was ABSOLUTELY AMAZED with the difference!!! There was almost no clatter at start up, it ran quieter when it was hot and used at least 75% less oil between changes. I don't have any issues with the M1 in the CTS though, so I'm sticking with it for now. I also don't try to race every Cobra I come across with my CTS!!

Now what are these condom thingys ya'll are talkin about??? I live by the tried and true method of "Pull & Pray!" (have I ever mentioned I have a son??)

was using mobile 1 in my bimmer with a bit of an oil burning problem and then switched to royal purple and the oil consumption problem completely went away. there was also a video on youtube someplace showing how RP will actually reverse engine wear
