I have one major caveat to what is being said, that I personally follow. Although some automatic transmissions, especially of older generations were good with multi-vehicle fluids, I believe that it is imperative to stick with exactly what it was designed for and no multi or universal fluids. I would apply this to CVT's and possibly DCT's too.
Manufacturers deny warranty all the time for wrong or universal transmission fluids. Then the company that did the exchange and or the manufacturer of the multivehicle transmission fluid might step up and cover the costs, while persuing the car manufacturer in court. Valvoline with it's Maxlife transmission fluid seems to have it's share of problems. This link below has a pdf that is really interesting about this. Also includes manuals of different car manufacturers like GM and Subaru and it's requirements for specific fluids. Subaru is clear to only use their engine oil with their new turbos.

Why won't you be running the Mobil 1 ESP (5W-30)? I thought this oil was a Dexos2 equivalent?
 
after calling a few dealers around here, I found one that claims to be using this oil for cruze diesels. Mobil Super™ 3000 Formula G 5W-30
I was pretty set on Mobil 1 ESP 5W30, but this looks very interesting. If the dealers are able to order this, this just might be the oil to use and just pay the difference on. It also looks to be dexos2 approved. Nice find!
 
PlasticPlant, Where are you located? You may be close to the dealer I called. You on the IL side?
I'm near Gurnee on the IL side. I was comparing the two and it does look like the ESP is the "better" oil, but not by much. Like I said, if the dealer can order this and they would allow us to just pay the difference this just might be the oil to go with (assuming it's a full synthetic).
 
I am impressed that a dealer in the US would even think of using something like this! Must be some good SA and/or parts people at that dealership. How much per quart? Is there a GM part number or something I can tell my dealer to look up?
Yes, a GM Part number would be great!
