I use zerex g05 in my other cummins. Of course it gets changedI think Dex-Cool is fine if your car came from the factory with it. Otherwise no.
I avoid the universal coolants and use a coolant designed for my engine although I am fine with a brand like Xerex.
Of course skip Dollar Tree brand oils and coolants.
