Unless it is doubling as their SN 5w30 for US vehicles also?
The Cruze diesel uses dexos2, and all GM cars sold in Europe (both gas/petrol and diesel) use dexos2 rather than dexos1.
Yep, Dexos2 is fairly similar to the Euro ACEA C3 spec. In Oz all the Dexos2 oils are also C3 oils.
The ACEA C3 is sort of a mid-SAPS, mid-TBN version of a ACEA A3/B4 oil.
In Oz the iTi 1.4 L turbo petrol engines on the Cruze are known to chew up oil, so GM-Australia say to use a high HTHS Dexos2 oil (>= 3.5 cP) rather that the lower HTHS Dexos1 oil. I personally would use an A3/B4 oil myself, but nobody asked me. Oh well....
