For a diesel Cruze, I would run any name brand, full synthetic, 5W-30 oil with the ACEA C3 spec., and sleep easy at night.
If I wanted more I would look for the DEXOS 2 or MB229.51 spec. I would probably go the MB as it is easier to find and a great standard.
The only DEXOS 2 oil I have seen around here is the valvoline SynPower MST 5W-40. It's rated C3, BMW LL04, MB 2295.51 and DEXOS 2. It's a little heavy, but that wouldn't bother me too much once the car was out of warranty.
Still I would probably go for the SynPower XL-III 5W-30 which is rated ACEA C3, BMW LL-04 and MB229.51.
We also have a Castrol Edge Diesel 5W-30 which is ACEA C3 and BMW LL-04.
I'm sure there are more options, but that is what is stocked at my local store. If I had to buy one today, I would go the SynPower XL-III 5W-30.
