    Re: oil

    the slippery kind that's meant to go in my engine

    ...

    don't use aircraft engine oil, motorcycle oil, train engine oil or tractor oil ... use car oil

    but seriously, stick to what it says in your owners manual and don't worry about it

    you're very close to starting a war

    Re: oil

    Realize that the engine temp of this motor is higher then most - Mobil 1 - is pure junk, brakes down very quickly (them and Pennzoil have patents that say their synthetic oil is only a 50- 50 blend not pure) and doesn't maintain protection - I'm not sure how effective the Cadillac oil % rate is - I also have this system on my 08 Z06 and always change oil at 3000 to 3500 miles or 50% - it's timing - I use different fuild products - researched them for many months and have used them for many years!

    You can use whatever you like it's your car and your $$$

    Here's what I have in my 2011 CTS V Wagon and in my 2008 Z06 - Redline 5 - 30w in motor / Royal Purple 75 - 90 in rear end / ATE Blue and ATE 200 Brake fluids ( same fuilds just different color - making it easier when you bleed the system) / Trans fuild is actually the GM auto tranny fuild - seems to be the best for the auto - if you have a stick I use Royal Purple in my Z06.

    Re: oil

    Unless you are tracking the car or something else pretty extreme, the car has a 100,000 mile powertrain warranty if you use any oil that meets the owner's manual spec. While many people have their favorites and strong feelings one way or another, the fact is that you'd be hard pressed to be able to tell the difference between one oil and another under most circumstances in terms of how the car feels or drives. And the warranty is good regardless of the brand or flavor as long as it meets the designated spec.

    Or as Chris noted, use car oil and you'll be good. Don't overthink your oil - there's a lot of other places these cars can use extra attention before you fret over the oil.

    Any dexos 1 oil. Mobile 1 is what I have because it is easy to find. I've heard penzoil platinum is the best walmart oil. An ester based oil like redline or motul should be the best though.

    Re: oil

    Since Cadillac changes the oil for FREE and I am leasing the car, AC Delco Synthetic Blend 5w30 Dexos 1 motor oil is what the dealer changes it with.

    If I planned on keeping the car, I would only run Amsoil 0w30 or 5w30 Signature Series. My second choice would be Mobil 1 5w30.

    Re: oil

    Mobil 1 5w30. My shop uses the same. 5k miles is a good number for a synth. but track/spirited use will obviously require more regular attention.

    Re: oil

    This is usually a religious war. I'm an electrical not a mechanical engineer, so if GM loads the car with Mobil 1 from the factory I figure that they have pretty thoroughly tested it since they warrant the engine for 100k. Who am I to think that I know better? Are there better oils - maybe - in fact probably. But the real question is how good is good enough. My MR-2 and Taco have used Mobil 1 since new. The MR-2 has 182k. The Taco 232k. Neither use oil. Seems like Mobil 1 has provided good enough protection.

    Re: oil

    Dogbreath,

    2011 and up CTS-Vs are no longer factory filled with Mobil 1. They come from the factory with AC Delco Synthetic Blend Dexos 1 approved 5w30 motor oil.

    2009 and 2010 CTS-Vs did come factory filled with Mobil 1 5w30.

    Motul 5-30 during the winter; 5-40 during spring-summer fall FTW (Its free )

    Gonna change the rear diff to Royal Purple to see if it helps the Diff overheat issue

    Re: oil

    I do what the owner's manual says because I don't track my car. The only deviation is that I change the oil when the DIC indicates 20%. That works out to 6000-7000 miles.
