From what has been in this thread, Mobil 1, Royal Purple, and Motul (among plenty of others) all have some oils on this list (but check to be sure the one you are using is on the list).
Of course, if you are tuned, or modded and don't worry about the warranty, by all means, find what you like.

In simple terms the "Dexos" standard is a set of minimum specs that GM set for worldwide use. In order to display the "Dexos1" seal on their oil an oil mfg must pay GM a royalty fee to put the label on their oil container. Amsoil Signature Series oil meets or exceeds the Dexos1 standard they just choose not to pay the royalty to GM. Here are several interesting reads for your education: http://www.amsoil.lube-direct.com/20...amsoil-has-it/ http://www.gm-trucks.com/forums/topi...onsumer-alert/ http://www.bobistheoilguy.com/forums...Number=2031364
