Oil Change Spec. for 2.0 LTZ Manual

Hey Guys,
My name is Dharam Kapadia i am new to this forum and I am from India.
The only variant available in india is the 2.0 Diesel engine of Chevy Cruze.
Further I would request you to please create a sub category for 2.0 Diesel Engines.

I have done 45K KMS / 28K Miles and its due for an Oil change. I gave my car in the chevy work shop and they only have one option which i am not convinced with.
If anyone has a good knowledge of Diesel engine or if anyone have a diesel cruze please share some option on oil change.

I researched a little and came across dexos2 5W30.

Please list a few more if you guys can.


Thanks & Regards

Dharam Kapadia
