Here is a link to the latest GM dexos oil lists. The last update was done as of 2/10/13.

What I find interesting is the inclusion of Castrol products, and of 5w-20. Still no Valvoline/Ashland products.
My recommendation is to stick with a 5w-30 dexos1 oil, especially if your Cruze is a LT/Eco/LTZ with the 1.4T.
