Fluids for new GM L31

I kinda had a feeling it didn't come from Chevy and I don't think it can hurt.

I run Castrol GTX 10w30 year round here in Oklahoma, does just fine. I also ditch dexcool any chance I get, don’t care what anyone says, that coolant is nasty so I always switch to the older green coolant. I have had several dexcool issues on more than one GM vehicle.
